Structure–property relationship of a complex photoluminescent arylacetylide-gold(I) compound. I: a pressure-induced phase transformation caught in the act

A pressure-induced triclinic-to-monoclinic phase transition has been caught `in the act' over a wider series of high-pressure synchrotron diffraction experiments conducted on a large, photoluminescent organo-gold(I) compound. Here, we describe the mechanism of this single-crystal-to-single-crystal phase transition, the onset of which occurs at ∼0.6 GPa, and we report a high-quality structure of the new monoclinic phase, refined using aspherical atomic scattering factors. Our case illustrates how conducting a fast series of diffraction experiments, enabled by modern equipment at synchrotron facilities, can lead to overestimation of the actual pressure of a phase transition due to slow transformation kinetics.

Structural characterization of TIR-domain signalosomes through a combination of structural biology approaches

The TIR (Toll/interleukin-1 receptor) domain represents a vital structural element shared by proteins with roles in immunity signalling pathways across phyla (from humans and plants to bacteria). Decades of research have finally led to identifying the key features of the molecular basis of signalling by these domains, including the formation of open-ended (filamentous) assemblies (responsible for the signalling by cooperative assembly formation mechanism, SCAF) and enzymatic activities involving the cleavage of nucleotides. We present a historical perspective of the research that led to this understanding, highlighting the roles that different structural methods played in this process: X-ray crystallography (including serial crystallography), microED (micro-crystal electron diffraction), NMR (nuclear magnetic resonance) spectroscopy and cryo-EM (cryogenic electron microscopy) involving helical reconstruction and single-particle analysis. This perspective emphasizes the complementarity of different structural approaches.

Solvent organization in the ultrahigh-resolution crystal structure of crambin at room temperature

Ultrahigh-resolution structures provide unprecedented details about protein dynamics, hydrogen bonding and solvent networks. The reported 0.70 Å, room-temperature crystal structure of crambin is the highest-resolution ambient-temperature structure of a protein achieved to date. Sufficient data were collected to enable unrestrained refinement of the protein and associated solvent networks using SHELXL. Dynamic solvent networks resulting from alternative side-chain conformations and shifts in water positions are revealed, demonstrating that polypeptide flexibility and formation of clathrate-type structures at hydro­phobic surfaces are the key features endowing crambin crystals with extraordinary diffraction power.

High-throughput nanoscale crystallization of di­hydro­pyridine active pharmaceutical ingredients

Single-crystal X-ray diffraction analysis of small molecule active pharmaceutical ingredients is a key technique in the confirmation of molecular connectivity, including absolute stereochemistry, as well as the solid-state form. However, accessing single crystals suitable for X-ray diffraction analysis of an active pharmaceutical ingredient can be experimentally laborious, especially considering the potential for multiple solid-state forms (solvates, hydrates and polymorphs). In recent years, methods for the exploration of experimental crystallization space of small molecules have undergone a `step-change', resulting in new high-throughput techniques becoming available. Here, the application of high-throughput encapsulated nanodroplet crystallization to a series of six di­hydro­pyridines, calcium channel blockers used in the treatment of hypertension related diseases, is described. This approach allowed 288 individual crystallization experiments to be performed in parallel on each molecule, resulting in rapid access to crystals and subsequent crystal structures for all six di­hydro­pyridines, as well as revealing a new solvate polymorph of nifedipine (1,4-dioxane solvate) and the first known solvate of nimodipine (DMSO solvate). This work further demonstrates the power of modern high-throughput crystallization methods in the exploration of the solid-state landscape of active pharmaceutical ingredients to facilitate crystal form discovery and structural analysis by single-crystal X-ray diffraction.

Attractive and repulsive forces in a crystal of [Rb(18-crown-6)][SbCl6] under high pressure

The compression behavior of [Rb(18-crown-6)][SbCl6] crystal under pressure up to 2.16 (3) GPa was investigated in a diamond anvil cell (DAC) using a mixture of pentane–iso­pentane (1:4) as the pressure-transmitting fluid. The compound crystallizes in trigonal space group R3 and no phase transition was observed in the indicated pressure range. The low value of pressure bulk modulus [9.1 (5) GPa] found in this crystal is a characteristic of soft materials with predominant dispersive and electrostatic interaction forces. The nonlinear relationship between unit-cell parameters under high pressure is attributed to the influence of reduced intermolecular H⋯Cl contacts under pressure over 0.73 GPa. It also explains the high compression efficiency of [Rb(18-crown-6)][SbCl6] crystals at relatively low pressures, resulting in a significant shift of the Rb atom to the center of the crown ether cavity. At pressures above 0.9 GPa, steric repulsion forces begin to play a remarkable role, since an increasing number of interatomic H⋯Cl and H⋯H contacts become shorter than the sum of their van der Waals (vdW) radii. Below 0.9 GPa, both unit-cell parameter dependences (P–a and P–c) exhibit hysteresis upon pressure release, demonstrating their influence on the disordered model of Rb atoms. The void reduction under pressure also demonstrates two linear sections with the inflection point at 0.9 GPa. Compression of the crystal is accompanied by a significant decrease in the volume of the voids, leading to the rapid approach of Rb atoms to the center of the crown ether cavity. For the Rb atom to penetrate into the center of the crown ether cavity in [Rb(18-crown-6)][SbCl6], it is necessary to apply a pressure of about 2.5 GPa to disrupt the balance of atomic forces in the crystal. This sample serves as a compression model demonstrating the influence of both attractive and repulsive forces on the change in unit-cell parameters under pressure.

Crystal structure solution and high-temperature thermal expansion in NaZr2(PO4)3-type materials

The NaZr2P3O12 family of materials have shown low and tailorable thermal expansion properties. In this study, SrZr4P6O24 (SrO·4ZrO2·3P2O5), CaZr4P6O24 (CaO·4ZrO2·3P2O5), MgZr4P6O24 (MgO·4ZrO2·3P2O5), NaTi2P3O12 [½(Na2O·4TiO2·3P2O5)], NaZr2P3O12 [½(Na2O·4ZrO2·3P2O5)], and related solid solutions were synthesized using the organic–inorganic steric entrapment method. The samples were characterized by in-situ high-temperature X-ray diffraction from 25 to 1500°C at the Advanced Photon Source and National Synchrotron Light Source II. The average linear thermal expansion of SrZr4P6O24 and CaZr4P6O24 was between −1 × 10−6 per °C and 6 × 10−6 per °C from 25 to 1500°C. The crystal structures of the high-temperature polymorphs of CaZr4P6O24 and SrZr4P6O24 with R3c symmetry were solved by Fourier difference mapping and Rietveld refinement. This polymorph is present above ∼1250°C. This work measured thermal expansion coefficients to 1500°C for all samples and investigated the differences in thermal expansion mechanisms between polymorphs and between compositions.

Crystal structures of two new high-pressure oxynitrides with composition SnGe4N4O4, from single-crystal electron diffraction

SnGe4N4O4 was synthesized at high pressure (16 and 20 GPa) and high temperature (1200 and 1500°C) in a large-volume press. Powder X-ray diffraction experiments using synchrotron radiation indicate that the derived samples are mixtures of known and unknown phases. However, the powder X-ray diffraction patterns are not sufficient for structural characterization. Transmission electron microscopy studies reveal crystals of several hundreds of nanometres in size with different chemical composition. Among them, crystals of a previously unknown phase with stoichiometry SnGe4N4O4 were detected and investigated using automated diffraction tomography (ADT), a three-dimensional electron diffraction method. Via ADT, the crystal structure could be determined from single nanocrystals in space group P63mc, exhibiting a nolanite-type structure. This was confirmed by density functional theory calculations and atomic resolution scanning transmission electron microscopy images. In one of the syntheses runs a rhombohedral 6R polytype of SnGe4N4O4 could be found together with the nolanite-type SnGe4N4O4. The structure of this polymorph was solved as well using ADT.

New insights into the magnetism and magnetic structure of LuCrO3 perovskite

A polycrystalline sample LuCrO3 has been characterized by neutron powder diffraction (NPD) and magnetization measurements. Its crystal structure has been Rietveld refined from NPD data in space group Pnma; this perovskite contains strongly tilted CrO6 octahedra with extremely bent Cr—O—Cr superexchange angles of ∼142°. The NPD data show that below Néel temperature (TN ≃ 131 K), the magnetic structure can be defined as an A-type antiferromagnetic arrangement of Cr3+ magnetic moments, aligned along the b axis, with a canting along the c axis. A noticeable magneto­strictive effect is observed in the unit-cell parameters and volume upon cooling down across TN. The AC magnetic susceptibility indicates the onset of magnetic ordering below 112.6 K; the magnetization isotherms below TN show a nonlinear behaviour that is associated with the described canting of the Cr3+ magnetic moments. From the Curie–Weiss law, the effective moment of the Cr3+ sublattice is found to be μeff = 3.55 μB (calculated 3.7 μB) while the ΘCW parameter yields a value of −155 K, indicating antiferromagnetic interactions. There is a conspicuous increase of TN upon the application of external pressure, which must be due to shortening of the Cr—O bond length under compression that increases the orbital overlap integral.

High-resolution crystal structure of the double nitrate hydrate [La(NO3)6]2[Ni(H2O)6]3·6H2O

This study introduces bis­[hexa­kis­(nitrato-κ2O,O')lanthanum(III)] tris­[hexa­aqua­nickel(II)] hexa­hydrate, [La(NO3)6]2[Ni(H2O)6]3·6H2O, with a structure refined in the hexa­gonal space group Roverline{3}. The salt com­prises [La(NO3)6]3− icosa­hedra and [Ni(H2O)6]2+ octa­hedra, thus forming an intricate network of inter­penetrating honeycomb lattices arranged in layers. This arrangement is stabilized through strong hydrogen bonds. Two successive layers are connected via the second [Ni(H2O)6]2+ octa­hedra, forming sheets which are stacked perpendicular to the c axis and held in the crystal by van der Waals forces. The synthesis of [La(NO3)6]2[Ni(H2O)6]3·6H2O involves dissolving lanthanum(III) and nickel(II) oxides in nitric acid, followed by slow evaporation, yielding green hexa­gonal plate-like crystals.

(U)SAXS characterization of porous microstructure of chert: insights into organic matter preservation

This study characterizes the microstructure and mineralogy of 132 (ODP sample), 1000 and 1880 million-year-old chert samples. By using ultra-small-angle X-ray scattering (USAXS), wide-angle X-ray scattering and other techniques, the preservation of organic matter (OM) in these samples is studied. The scarce microstructural data reported on chert contrast with many studies addressing porosity evolution in other sedimentary rocks. The aim of this work is to solve the distribution of OM and silica in chert by characterizing samples before and after combustion to pinpoint the OM distribution inside the porous silica matrix. The samples are predominantly composed of alpha quartz and show increasing crystallite sizes up to 33 ± 5 nm (1σ standard deviation or SD). In older samples, low water abundances (∼0.03%) suggest progressive dehydration. (U)SAXS data reveal a porous matrix that evolves over geological time, including, from younger to older samples, (1) a decreasing pore volume down to 1%, (2) greater pore sizes hosting OM, (3) decreasing specific surface area values from younger (9.3 ± 0.1 m2 g−1) to older samples (0.63 ± 0.07 m2 g−1, 1σ SD) and (4) a lower background intensity correlated to decreasing hydrogen abundances. The pore-volume distributions (PVDs) show that pores ranging from 4 to 100 nm accumulate the greater volume fraction of OM. Raman data show aromatic organic clusters up to 20 nm in older samples. Raman and PVD data suggest that OM is located mostly in mesopores. Observed structural changes, silica–OM interactions and the hydro­phobicity of the OM could explain the OM preservation in chert.

Time-resolved high-energy X-ray diffraction studies of ultrathin Ni ferrite films on MgO(001)

Time-resolved high-energy X-ray diffraction was used during growth of ultrathin NixFe3−xO4 films with varying Ni content (0 ≤ x ≤ 1.5) deposited on MgO(001) substrates by reactive molecular beam epitaxy, providing an insight into the growth dynamics of these films. In order to obtain structural information, reciprocal-space maps were recorded and the temporal evolution of the Bragg peaks specific to the octahedral and tetrahedral lattice sites of the inverse spinel structure of NixFe3−xO4 was observed during growth of the films. A time delay, corresponding to a coverage of 1.2–1.8 nm, between the appearance of the Bragg reflections originating from octahedral sites and reflections originating exclusively from tetrahedral sites indicates that the ferrite films grow in two stages. In the initial growth phase, a rock salt interface layer is formed. Afterwards, a structural transition occurs and the films grow in an inverse spinel structure. The thickness of the initial rock salt phase was found to increase with Ni content and to be responsible for atypical strain in the thin films. Films with Ni contents x > 1 do not show a structural transition. These films remain in a (deficient) rock salt structure consisting of a mixed Ni–Fe oxide and do not form a spinel structure at all. They show an increased number of NiO clusters as detected by X-ray photoelectron spectroscopy of the valence band, accompanied by a significant roughening of the films.

Texture measurements on quartz single crystals to validate coordinate systems for neutron time-of-flight texture analysis

In crystallographic texture analysis, ensuring that sample directions are preserved from experiment to the resulting orientation distribution is crucial to obtain physical meaning from diffraction data. This work details a procedure to ensure instrument and sample coordinates are consistent when analyzing diffraction data with a Rietveld refinement using the texture analysis software MAUD. A quartz crystal is measured on the HIPPO diffractometer at Los Alamos National Laboratory for this purpose. The methods described here can be applied to any diffraction instrument measuring orientation distributions in polycrystalline materials.

Unlocking the surface chemistry of ionic minerals: a high-throughput pipeline for modeling realistic interfaces

A systematic procedure is introduced for modeling charge-neutral non-polar surfaces of ionic minerals containing polyatomic anions. By integrating distance- and charge-based clustering to identify chemical species within the mineral bulk, our pipeline, PolyCleaver, renders a variety of theoretically viable surface terminations. As a demonstrative example, this approach was applied to forsterite (Mg2SiO4), unveiling a rich interface landscape based on interactions with formaldehyde, a relevant multifaceted molecule, and more particularly in prebiotic chemistry. This high-throughput method, going beyond techniques traditionally applied in the modeling of minerals, offers new insights into the potential catalytic properties of diverse surfaces, enabling a broader exploration of synthetic pathways in complex mineral systems.

Upgrade of crystallography beamline BL19U1 at the Shanghai Synchrotron Radiation Facility

BL19U1, an energy-tunable protein complex crystallography beamline at the Shanghai Synchrotron Radiation Facility, has emerged as one of the most productive MX beamlines since opening to the public in July 2015. As of October 2023, it has contributed to over 2000 protein structures deposited in the Protein Data Bank (PDB), resulting in the publication of more than 1000 scientific papers. In response to increasing interest in structure-based drug design utilizing X-ray crystallography for fragment library screening, enhancements have been implemented in both hardware and data collection systems on the beamline to optimize efficiency. Hardware upgrades include the transition from MD2 to MD2S for the diffractometer, alongside the installation of a humidity controller featuring a rapid nozzle exchanger. This allows users to opt for either low-temperature or room-temperature data collection modes. The control system has been upgraded from Blu-Ice to MXCuBE3, which supports website-mode data collection, providing enhanced compatibility and easy expansion with new features. An automated data processing pipeline has also been developed to offer users real-time feedback on data quality.

Novel high-efficiency 2D position-sensitive ZnS:Ag/6LiF scintillator detector for neutron diffraction

Scintillator-based ZnS:Ag/6LiF neutron detectors have been under development at ISIS for more than three decades. Continuous research and development aim to improve detector capabilities, achieve better performance and meet the increasingly demanding requirements set by neutron instruments. As part of this program, a high-efficiency 2D position-sensitive scintillator detector with wavelength-shifting fibres has been developed for neutron-diffraction applications. The detector consists of a double scintillator-fibre layer to improve detection efficiency. Each layer is made up of two orthogonal fibre planes placed between two ZnS:Ag/6LiF scintillator screens. Thin reflective foils are attached to the front and back scintillators of each layer to minimize light cross-talk between layers. The detector has an active area of 192 × 192 mm with a square pixel size of 3 × 3 mm. As part of the development process of the double-layer detector, a single-layer detector was built, together with a prototype detector in which the two layers of the detector could be read out separately. Efficiency calculations and measurements of all three detectors are discussed. The novel double-layer detector has been installed and tested on the SXD diffractometer at ISIS. The detector performance is compared with the current scintillator detectors employed on SXD by studying reference crystal samples. More than a factor of 3 improvement in efficiency is achieved with the double-layer wavelength-shifting-fibre detector. Software routines for further optimizations in spatial resolution and uniformity of response have been implemented and tested for 2D detectors. The methods and results are discussed in this manuscript.

Synthesis and in-depth structure determination of a novel metastable high-pressure CrTe3 phase

This study reports the synthesis and crystal structure determination of a novel CrTe3 phase using various experimental and theoretical methods. The average stoichiometry and local phase separation of this quenched high-pressure phase were characterized by ex situ synchrotron powder X-ray diffraction and total scattering. Several structural models were obtained using simulated annealing, but all suffered from an imperfect Rietveld refinement, especially at higher diffraction angles. Finally, a novel stoichiometrically correct crystal structure model was proposed on the basis of electron diffraction data and refined against powder diffraction data using the Rietveld method. Scanning electron microscopy–energy-dispersive X-ray spectrometry (EDX) measurements verified the targeted 1:3 (Cr:Te) average stoichiometry for the starting compound and for the quenched high-pressure phase within experimental errors. Scanning transmission electron microscopy (STEM)–EDX was used to examine minute variations of the Cr-to-Te ratio at the nanoscale. Precession electron diffraction (PED) experiments were applied for the nanoscale structure analysis of the quenched high-pressure phase. The proposed monoclinic model from PED experiments provided an improved fit to the X-ray patterns, especially after introducing atomic anisotropic displacement parameters and partial occupancy of Cr atoms. Atomic resolution STEM and simulations were conducted to identify variations in the Cr-atom site-occupancy factor. No significant variations were observed experimentally for several zone axes. The magnetic properties of the novel CrTe3 phase were investigated through temperature- and field-dependent magnetization measurements. In order to understand these properties, auxiliary theoretical investigations have been performed by first-principles electronic structure calculations and Monte Carlo simulations. The obtained results allow the observed magnetization behavior to be interpreted as the consequence of competition between the applied magnetic field and the Cr–Cr exchange interactions, leading to a decrease of the magnetization towards T = 0 K typical for antiferromagnetic systems, as well as a field-induced enhanced magnetization around the critical temperature due to the high magnetic susceptibility in this region.

Demonstration of neutron time-of-flight diffraction with an event-mode imaging detector

Neutron diffraction beamlines have traditionally relied on deploying large detector arrays of 3He tubes or neutron-sensitive scintillators coupled with photomultipliers to efficiently probe crystallographic and microstructure information of a given material. Given the large upfront cost of custom-made data acquisition systems and the recent scarcity of 3He, new diffraction beamlines or upgrades to existing ones demand innovative approaches. This paper introduces a novel Timepix3-based event-mode imaging neutron diffraction detector system as well as first results of a silicon powder diffraction measurement made at the HIPPO neutron powder diffractometer at the Los Alamos Neutron Science Center. Notably, these initial measurements were conducted simultaneously with the 3He array on HIPPO, enabling direct comparison. Data reduction for this type of data was implemented in the MAUD code, enabling Rietveld analysis. Results from the Timepix3-based setup and HIPPO were benchmarked against McStas simulations, showing good agreement for peak resolution. With further development, systems such as the one presented here may substantially reduce the cost of detector systems for new neutron instrumentation as well as for upgrades of existing beamlines.

Mix and measure II: joint high-energy laboratory powder diffraction and microtomography for cement hydration studies

Portland cements (PCs) and cement blends are multiphase materials of different fineness, and quantitatively analysing their hydration pathways is very challenging. The dissolution (hydration) of the initial crystalline and amorphous phases must be determined, as well as the formation of labile (such as ettringite), reactive (such as portlandite) and amorphous (such as calcium silicate hydrate gel) components. The microstructural changes with hydration time must also be mapped out. To address this robustly and accurately, an innovative approach is being developed based on in situ measurements of pastes without any sample conditioning. Data are sequentially acquired by Mo Kα1 laboratory X-ray powder diffraction (LXRPD) and microtomography (µCT), where the same volume is scanned with time to reduce variability. Wide capillaries (2 mm in diameter) are key to avoid artefacts, e.g. self-desiccation, and to have excellent particle averaging. This methodology is tested in three cement paste samples: (i) a commercial PC 52.5 R, (ii) a blend of 80 wt% of this PC and 20 wt% quartz, to simulate an addition of supplementary cementitious materials, and (iii) a blend of 80 wt% PC and 20 wt% limestone, to simulate a limestone Portland cement. LXRPD data are acquired at 3 h and 1, 3, 7 and 28 days, and µCT data are collected at 12 h and 1, 3, 7 and 28 days. Later age data can also be easily acquired. In this methodology, the amounts of the crystalline phases are directly obtained from Rietveld analysis and the amorphous phase contents are obtained from mass-balance calculations. From the µCT study, and within the attained spatial resolution, three components (porosity, hydrated products and unhydrated cement particles) are determined. The analyses quantitatively demonstrate the filler effect of quartz and limestone in the hydration of alite and the calcium aluminate phases. Further hydration details are discussed.

Quality assessment of the wide-angle detection option planned at the high-intensity/extended Q-range SANS diffractometer KWS-2 combining experiments and McStas simulations

For a reliable characterization of materials and systems featuring multiple structural levels, a broad length scale from a few ångström to hundreds of nanometres must be analyzed and an extended Q range must be covered in X-ray and neutron scattering experiments. For certain samples or effects, it is advantageous to perform such characterization with a single instrument. Neutrons offer the unique advantage of contrast variation and matching by D-labeling, which is of great value in the characterization of natural or synthetic polymers. Some time-of-flight small-angle neutron scattering (TOF-SANS) instruments at neutron spallation sources can cover an extended Q range by using a broad wavelength band and a multitude of detectors. The detectors are arranged to cover a wide range of scattering angles with a resolution that allows both large-scale morphology and crystalline structure to be resolved simultaneously. However, for such analyses, the SANS instruments at steady-state sources operating in conventional monochromatic pinhole mode rely on additional wide-angle neutron scattering (WANS) detectors. The resolution must be tuned via a system of choppers and a TOF data acquisition option to reliably measure the atomic to mesoscale structures. The KWS-2 SANS diffractometer at Jülich Centre for Neutron Science allows the exploration of a wide Q range using conventional pinhole and lens focusing modes and an adjustable resolution Δλ/λ between 2 and 20%. This is achieved through the use of a versatile mechanical velocity selector combined with a variable slit opening and rotation frequency chopper. The installation of WANS detectors planned on the instrument required a detailed analysis of the quality of the data measured over a wide angular range with variable resolution. This article presents an assessment of the WANS performance by comparison with a McStas [Willendrup, Farhi & Lefmann (2004). Physica B, 350, E735–E737] simulation of ideal experimental conditions at the instrument.

Revealing nanoscale sorption mechanisms of gases in a highly porous silica aerogel

Geological formations provide a promising environment for the long-term and short-term storage of gases, including carbon dioxide, hydrogen and hydro­carbons, controlled by the rock-specific small-scale pore structure. This study investigates the nanoscale structure and gas uptake in a highly porous silica aerogel (a synthetic proxy for natural rocks) using transmission electron microscopy, X-ray diffraction, and small-angle and ultra-small-angle neutron scattering with a tracer of deuterated methane (CD4) at pressures up to 1000 bar. The results show that the adsorption of CD4 in the porous silica matrix is scale dependent. The pore space of the silica aerogel is fully accessible to the invading gas, which quickly equilibrates with the external pressure and shows no condensation on the sub-nanometre scale. In the 2.5–50 nm pore size region a classical two-phase adsorption behaviour is observed. The structure of the aerogel returns to its original state after the CD4 pressure has been released.

The promise of GaAs 200 in small-angle neutron scattering for higher resolution

The Q resolution in Bonse–Hart double-crystal diffractometers is determined for a given Bragg angle by the value of the crystallographic structure factor. To date, the reflections Si 220 or Si 111 have been used exclusively in neutron scattering, which provide resolutions for triple-bounce crystals of about 2 × 10−5 Å−1 (FWHM). The Darwin width of the GaAs 200 reflection is about a factor of 10 smaller, offering the possibility of a Q resolution of 2 × 10−6 Å−1 provided crystals of sufficient quality are available. This article reports a feasibility study with single-bounce GaAs 200, yielding a Q resolution of 4.6 × 10−6 Å−1, six times superior in comparison with a Si 220 setup.

Multidimensional Rietveld refinement of high-pressure neutron diffraction data of PbNCN

High-pressure neutron powder diffraction data from PbNCN were collected on the high-pressure diffraction beamline SNAP located at the Spallation Neutron Source (SNS) of Oak Ridge National Laboratory (Tennessee, USA). The diffraction data were analyzed using the novel method of multidimensional (two dimensions for now, potentially more in the future) Rietveld refinement and, for comparison, employing the conventional Rietveld method. To achieve two-dimensional analysis, a detailed description of the SNAP instrument characteristics was created, serving as an instrument parameter file, and then yielding both cell and spatial parameters as refined under pressure for the first time for solid-state cyanamides/carbodi­imides. The bulk modulus B0 = 25.1 (15) GPa and its derivative B'0 = 11.1 (8) were extracted for PbNCN following the Vinet equation of state. Surprisingly, an internal transition was observed beyond 2.0 (2) GPa, resulting from switching the bond multiplicities (and bending direction) of the NCN2− complex anion. The results were corroborated using electronic structure calculation from first principles, highlighting both local structural and chemical bonding details.

VMXm – A sub-micron focus macromolecular crystallography beamline at Diamond Light Source

VMXm joins the suite of operational macromolecular crystallography beamlines at Diamond Light Source. It has been designed to optimize rotation data collections from protein crystals less than 10 µm and down to below 1 µm in size. The beamline has a fully focused beam of 0.3 × 2.3 µm (vertical × horizontal) with a tuneable energy range (6–28 keV) and high flux (1.6 × 1012 photons s−1 at 12.5 keV). The crystals are housed within a vacuum chamber to minimize background scatter from air. Crystals are plunge-cooled on cryo-electron microscopy grids, allowing much of the liquid surrounding the crystals to be removed. These factors improve the signal-to-noise during data collection and the lifetime of the microcrystals can be prolonged by exploiting photoelectron escape. A novel in vacuo sample environment has been designed which also houses a scanning electron microscope to aid with sample visualization. This combination of features at VMXm allows measurements at the physical limits of X-ray crystallography on biomacromolecules to be explored and exploited.

Upgraded front ends for SLS 2.0 with next-generation high-power diaphragms and slits

The upgrade of the Swiss Light Source, called SLS 2.0, necessitates comprehensive updates to all 18 user front ends. This upgrade is driven by the increased power of the synchrotron beam, reduced floor space, changing source points, new safety regulations and enhanced beam properties, including a brightness increase by up to a factor of 40. While some existing front-end components are being thoroughly refurbished and upgraded for safety reasons, other components, especially those designed to tailor the new synchrotron beam, are being completely rebuilt. These new designs feature innovative and enhanced cooling systems to manage the high-power load and meet new requirements such as mechanical stability and compact footprints.

Correlative X-ray micro-nanotomography with scanning electron microscopy at the Advanced Light Source

Geological samples are inherently multi-scale. Understanding their bulk physical and chemical properties requires characterization down to the nano-scale. A powerful technique to study the three-dimensional microstructure is X-ray tomography, but it lacks information about the chemistry of samples. To develop a methodology for measuring the multi-scale 3D microstructure of geological samples, correlative X-ray micro- and nanotomography were performed on two rocks followed by scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS) analysis. The study was performed in five steps: (i) micro X-ray tomography was performed on rock sample cores, (ii) samples for nanotomography were prepared using laser milling, (iii) nanotomography was performed on the milled sub-samples, (iv) samples were mounted and polished for SEM analysis and (v) SEM imaging and compositional mapping was performed on micro and nanotomography samples for complimentary information. Correlative study performed on samples of serpentine and basalt revealed multiscale 3D structures involving both solid mineral phases and pore networks. Significant differences in the volume fraction of pores and mineral phases were also observed dependent on the imaging spatial resolution employed. This highlights the necessity for the application of such a multiscale approach for the characterization of complex aggregates such as rocks. Information acquired from the chemical mapping of different phases was also helpful in segmentation of phases that did not exhibit significant contrast in X-ray imaging. Adoption of the protocol used in this study can be broadly applied to 3D imaging studies being performed at the Advanced Light Source and other user facilities.

Mitigation of DMM-induced stripe patterns in synchrotron X-ray radiography through dynamic tilting

In synchrotron X-ray radiography, achieving high image resolution and an optimal signal-to-noise ratio (SNR) is crucial for the subsequent accurate image analysis. Traditional methods often struggle to balance these two parameters, especially in situ applications where rapid data acquisition is essential to capture specific dynamic processes. For quantitative image data analysis, using monochromatic X-rays is essential. A double multilayer monochromator (DMM) is successfully used for this aim at the BAMline, BESSY II (Helmholtz Zentrum Berlin, Germany). However, such DMMs are prone to producing an unstable horizontal stripe pattern. Such an unstable pattern renders proper signal normalization difficult and thereby causes a reduction of the SNR. We introduce a novel approach to enhance SNR while preserving resolution: dynamic tilting of the DMM. By adjusting the orientation of the DMM during the acquisition of radiographic projections, we optimize the X-ray imaging quality, thereby enhancing the SNR. The corresponding shift of the projection during this movement is corrected in post-processing. The latter correction allows a good resolution to be preserved. This dynamic tilting technique enables the homogenization of the beam profile and thereby effectively reduces noise while maintaining high resolution. We demonstrate that data captured using this proposed technique can be seamlessly integrated into the existing radiographic data workflow, as it does not need hardware modifications to classical X-ray imaging beamline setups. This facilitates further image analysis and processing using established methods.

X-ray ghost imaging with a specially developed beam splitter

X-ray ghost imaging with a crystal beam splitter has advantages in highly efficient imaging due to the simultaneous acquisition of signals from both the object beam and reference beam. However, beam splitting with a large field of view, uniform distribution and high correlation has been a great challenge up to now. Therefore, a dedicated beam splitter has been developed by optimizing the optical layout of a synchrotron radiation beamline and the fabrication process of a Laue crystal. A large field of view, consistent size, uniform intensity distribution and high correlation were obtained simultaneously for the two split beams. Modulated by a piece of copper foam upstream of the splitter, a correlation of 92% between the speckle fields of the object and reference beam and a Glauber function of 1.25 were achieved. Taking advantage of synthetic aperture X-ray ghost imaging (SAXGI), a circuit board of size 880 × 330 pixels was successfully imaged with high fidelity. In addition, even though 16 measurements corresponding to a sampling rate of 1% in SAXGI were used for image reconstruction, the skeleton structure of the circuit board can still be determined. In conclusion, the specially developed beam splitter is applicable for the efficient implementation of X-ray ghost imaging.

High-transmission spectrometer for rapid resonant inelastic soft X-ray scattering (rRIXS) maps

The design and first results of a high-transmission soft X-ray spectrometer operated at the X-SPEC double-undulator beamline of the KIT Light Source are presented. As a unique feature, particular emphasis was placed on optimizing the spectrometer transmission by maximizing the solid angle and the efficiencies of spectrometer gratings and detector. A CMOS detector, optimized for soft X-rays, allows for quantum efficiencies of 90% or above over the full energy range of the spectrometer, while simultaneously offering short readout times. Combining an optimized control system at the X-SPEC beamline with continuous energy scans (as opposed to step scans), the high transmission of the spectrometer, and the fast readout of the CMOS camera, enable the collection of entire rapid resonant inelastic soft X-ray scattering maps in less than 1 min. Series of spectra at a fixed energy can be taken with a frequency of up to 5 Hz. Furthermore, the use of higher-order reflections allows a very wide energy range (45 to 2000 eV) to be covered with only two blazed gratings, while keeping the efficiency high and the resolving power E/ΔE above 1500 and 3000 with low- and high-energy gratings, respectively.

October Report Highlights Big Gains in Crypto Mining Efficiency and Expansion

Source: Streetwise Reports 11/06/2024

Terawulf Inc. (WULF:NASDAQ) has reported its October 2024 production and operations. Read more about the companys mining efficiency gains, expansion plans, and high-performance computing initiatives.

Terawulf Inc. (WULF:NASDAQ) has reported its October 2024 production and operations. The report included significant advancements in self-mining with an operational capacity reaching 8.1 exahash per second (EH/s). This marks a 62% increase from the prior year. The company mined a total of 150 bitcoins during the month, averaging approximately 4.8 bitcoins per day, at a power cost of US$36,789 per bitcoin mined or about US$0.048 per kWh (kilowatt-hour). To improve efficiency, TeraWulf continued its miner refresh program at its Lake Mariner facility, replacing older models with upgraded S19 XP miners following its sale of interest in the Nautilus Cryptomine facility, which enabled additional hardware acquisitions.

Focusing on high-performance computing (HPC) infrastructure, TeraWulf's aim is to establish 72.5 MW HPC hosting capacity at Lake Mariner by Q2 2025. October's operational hash rate averaged 6.8 EH/s, with adjustments made for demand response events and performance optimization measures to enhance profitability. Construction on the company's 20 MW HPC hosting facility, CB-1, remains on schedule for Q1 2025, and a larger 50 MW HPC facility, CB-2, is expected by Q2 2025. The recent sale of TeraWulf's equity interest in Nautilus and new financing through convertible notes are anticipated to support these growth initiatives.

Sean Farrell, Senior Vice President of Operations at TeraWulf, explained in the press release, "October marked another productive month, with TeraWulf mining 150 bitcoin and sustaining an average daily production of around 5 bitcoin . . . In line with our previously outlined plans, we are accelerating the transition to more efficient mining hardware by replacing older miners at Lake Mariner with S19 XP models. We are also working closely with Bitmain's warranty department on a recovery plan to repair and replace 1.5 EH of mining equipment with a target completion by the end of the year. Furthermore, we have established a dedicated Business Development and Performance Optimization team focused on integrating advanced IT and software solutions to improve our operational hash rate and overall efficiency. Building 5, which has been designed to handle higher heat exhaust of the latest generation miners, remains on track to be operational in Q1 2025."

Why Crypto Mining?

The cryptocurrency mining sector has seen recent momentum, bolstered by the U.S. election results and the evolving landscape for Bitcoin. As Benzinga reported on November 6, bitcoin mining stocks experienced notable gains following the U.S. presidential election, which led to Bitcoin reaching record highs. The outcome was anticipated to benefit U.S.-focused mining companies as pro-crypto policies, including a preference for domestic bitcoin production, gained prominence. Benzinga noted that Trump had previously expressed support for more bitcoin mining within the U.S., a stance that influenced broader market optimism in the days following his election.

On November 4, Yahoo! Finance highlighted the growing trend among Bitcoin miners to integrate artificial intelligence (AI) to power a "new industrial revolution." As described by Rob Nelson, who emphasized the impact of cryptocurrency mining as a vehicle for both economic and technological change. This trend has driven miners to secure deals within the AI sector, given the synergies in computational power required for both cryptocurrency and AI initiatives. Nelson projected that this cross-industry expansion could have far-reaching effects, creating value for both miners and AI-focused enterprises.

Additionally, a November 6 report from Time explored the significance of the recent Presidential election outcome for the crypto industry's future regulatory environment. According to Time, Trump's support for the industry included ambitions to boost the country's bitcoin mining footprint, which aligned with crypto PACs' efforts to secure pro-crypto candidates. The article reported that these advocacy groups saw the election as an opportunity to reshape crypto regulation and encourage growth in U.S.-based bitcoin mining.

TeraWulf's Catalysts

TeraWulf's recent initiatives set a foundation for further growth and operational efficiency. According to the company's investor presentation, the sale of its 25% equity interest in the Nautilus facility enhances liquidity. This enables TeraWulf to reinvest in its flagship Lake Mariner site for both HPC and AI expansion.

The transaction also reduces exposure to the expiring Nautilus 2¢ power contract by 2027, positioning the company to benefit from projected power price increases at Lake Mariner. This strategic realignment is anticipated to improve fleet efficiency, with an upgraded mining fleet targeting 13 EH/s by Q1 2025, supported by the deployment of next-gen S21 Pro miners.

What Experts Are Saying...

On November 5, 2024, Roth MKM analyst Darren Aftahi assigned TeraWulf a "Buy" rating and set a price target of US$7.50. Roth highlighted optimism around the company's expansion and potential in high-performance computing (HPC) and bitcoin mining. Roth noted that TeraWulf's planned 72.5 MW of HPC capacity by Q2 2025 could generate annualized revenue of approximately US$90 million, with over US$60 million in profit. [OWNERSHIP_CHART-11184]

The report highlighted the completion of TeraWulf's initial 2.5 MW HPC project and its upcoming 20 MW facility, which remains on track for Q1 2025. Roth analysts pointed to the operational progress at TeraWulf's Lake Mariner facility, emphasizing the company's improvements in mining efficiency with new S19 XP models, which brought its machine efficiency to 22 J/TH.

In-Flight Internet Services Co. Beats Expectations in Q3/24

Source: Scott Searle 11/08/2024

In line-to-better than expected financial results are good enough pre-launch of the satellite broadband solution, expected in Q4/24, noted a Roth MKM report.

Gogo Inc. (GOGO:NASDAQ) reported its Q3/24 financial results, and they slightly exceeded expectations, reported Scott Searle, managing director at Roth MKM, in a Nov. 5 research note.

The company provides in-flight connectivity services to business aviation markets through its North American terrestrial air-to-ground network.

137% Potential Return

Roth maintained its target price of US$15.50 per share on Gogo, noted Searle.

"We believe this provides a reasonable 12-plus-month target given the expected impact from two major new product cycles as we enter 2025," he wrote, referring to Galileo, the company's global inflight broadband service, and its 5G product line.

In comparison, the company's share price at the time of the report was about US$6.55 per share. From this price, the return to target reflects 137% upside.

Gogo remains a Buy.

Quarter's Highlights

Searle reported that Gogo's Q3/24 service revenue was a beat. At US$81.9 million (US$81.9M), it was slightly higher than that in Q2/24 and driven by modestly better-than-expected aircraft online, Searle reported. This revenue exceeded Roth's estimate by about US$300,000.

Also of note, Galileo is on track to launch in Q4/24, and Gogo continues to grow its portfolio of supplemental type certificates and partners around the world.

A Look Ahead

Gogo's outlook for 2024 of US$400-410M encompasses consensus' estimate, noted Searle. The company, though, has "pulled long-term guidance ahead of the Satcom Direct [acquisition] closing."

Roth expects Galileo and 5G will lead recovery, expected in late 2025.

In other news, noted Searle, Gogo Chairman and Chief Executive Officer Oakleigh Thorne will present at Roth's NYC Tech Event on Nov. 20.

Simon Pegg fights 'beige' life in 'Hector and the Search for Happiness'

British actor Simon Pegg has had the chance to take on some pretty fun roles. He’s battled zombies in Shaun of the Dead. He’s taken on the role of Scotty in the J.J. Abrams reboot of "Star Trek." And he plays an Impossible Missions Force technician alongside Tom Cruise in the Mission Impossible film series.

In his latest film release, Pegg plays Hector, a psychiatrist who decides his life is just too “beige,” so he sets out into the world to find out what makes people truly happy.

Pegg joins Take Two to talk about what Hector’s journey brings him in “Hector and the Search for Happiness.”

“Hector and the Search for Happiness” opens in the U.S. September 19th.

Interview Highlights:
 

On prepping to play the psychiatrist, Hector:

“Rosamund Pike and I…had dinner with a psychiatrist prior to starting shooting just to see, sort of, how he felt about dealing with people who have problems which aren’t necessarily, real problems, you know; which are what people call first world problems on Twitter.”

Why Hector sets out on his journey:

"I think Hector, at the beginning of the film, has a life that is very satisfactory; and to that degree, he’s unhappy…And, you know, what he learns is, you need more than that emotionally in your life to truly be happy. You know, if everything’s kind of just beige, you’re never going to be happy. You need to know misery, you need to know fear, and you need to know abandonment."

A little perspective:

"It was a very interesting thing to be shooting in Johannesburg, and to get out into…the townships…and see societies which contend with just abject poverty, and hardship everyday; but seeing so many smiles, and so many people genuinely joyful. And then get into the interior of Johannesburg, where there’s a lot of white people living in, sort of, gated communities, terrified...And see less smiles. It’s a very odd thing. And very, in keeping with the message of the film, which is, avoiding unhappiness is not the root to happiness.”

On his favorite emotion to convey as an actor – happiness, sadness, or anger:

“It’s a weird thing, I think, acting, sometimes. I sometimes almost resent it because you go through this sort of Pavlovian trauma sometimes because you have to recreate certain things that are sometimes a bit stressful.”

“Happiness is always a nice one because it’s fun to laugh on screen or to recreate moments of joy or euphoria, cause you do get a buzz from it, you know, you get this…vicarious, sort of, happiness in yourself. But that works as well for having to replicate sadness, or fear, or anger, or love even. “

“Your body thinks, ‘Oh, are we doing this now? Are we in love with someone here? Are we scared of something [laughs]?’ And you have to constantly intellectualize and remind your hormones that you’re actually – ‘No. This is fake, okay. You’re actually not about to die.’”

High-Grade Uranium Discovery Confirms Potential at Northern Saskatchewan Projects

Source: Streetwise Reports 10/18/2024

Aero Energy Ltd. (AERO:TSXV; AAUGF:OTC; UU3:FRA) has announced significant advancements at its Murmac and Sun Dog uranium projects in Northern Saskatchewan. Read how this and a CA$2.5-million non-brokered private placement aim the company towards further exploration.

Aero Energy Ltd. (AERO:TSXV; AAUGF:OTC; UU3:FRA) has announced significant advancements at its Murmac and Sun Dog uranium projects in Northern Saskatchewan, with the first drill program revealing high-grade uranium potential. Situated near Uranium City on the Athabasca Basin's northern margin, the projects aim to capitalize on basement-hosted uranium deposits similar to high-grade discoveries in the region.

The initial drill campaign completed 16 holes, targeting 12 key areas, with 12 holes yielding anomalous radioactivity. A major highlight is the new high-grade uranium discovery in drill hole M24-017, which intersected 8.4 meters of mineralization at 0.3% U3O8, including assays peaking at 13.8% U3O8 at just 64 meters below surface. The results confirm Aero's exploration model, which focuses on basement-hosted deposits within graphitic structures, a common feature in Athabasca Basin uranium deposits like Arrow and Triple R.

"From the launch of the company in January, we took a very diligent yet aggressive approach to discovery," stated Galen McNamara, CEO of Aero Energy. "The combination of historical data and the results from the first drill program serve as evidence that basement-hosted mineralization akin to the large deposits beneath and adjacent to the Athabasca Basin is present in the area."

The Murmac project spans 25,607 acres and holds a production legacy of approximately 70 million pounds of U3O8. Similarly, the 48,443-acre Sun Dog property hosts the historic Gunnar uranium mine, which once held the title of the world's largest uranium producer. Past exploration focused on fault-hosted mineralization, missing the basement-hosted uranium potential that Aero's recent findings have validated.

Recent exploration efforts included a VTEM Plus survey, flown over 3,350 kilometers, identifying graphite-rich rocks that support Aero's exploration thesis. Additionally, two new occurrences of strong radioactivity were identified at surface-level scout locations: Target A15 showed 60,793 counts per second, and Target P4 displayed 13,533 counts per second. Summer 2024 drilling included 1,550 meters at Murmac and 1,600 meters at Sun Dog, highlighting shallow, high-grade potential in both areas.

In parallel, Aero Energy has announced a CA$2.5 million non-brokered private placement to support further exploration. The proceeds from flow-through units will fund work programs across Murmac, Sun Dog, and the Strike property, with the remaining funds allocated to general working capital.

Why Uranium?

The uranium sector has recently experienced strong growth, largely driven by increasing global demand and efforts to diversify from Russian supply chains. On September 30, The New York Times discussed the resurgence in Western uranium production, highlighting that "uranium mines are ramping up across the West, spurred by rising demand for electricity and federal efforts to cut Russia out of the supply chain." Aero Energy's recent discoveries and forthcoming winter drilling plans at Murmac and Sun Dog reflect this trend, with CEO Galen McNamara remarking, "The combination of historical data and the results from the first drill program serve as evidence that basement-hosted mineralization . . . is present in the area," suggesting strong potential for the Canadian uranium market to contribute to non-Russian nuclear fuel supplies.

Jeff Clark of The Gold Advisor highlighted his continued confidence in the company by stating, "I remain overweight the stock."

On October 9, Reuters reported that demand from U.S. buyers has been on the rise, as "a strong rise in demand from its U.S. customers" pushed Orano's recent plans to expand uranium enrichment in the United States and France. This shift underscores Aero Energy's recent investments in Northern Saskatchewan, where the company has identified high-grade uranium mineralization in both the Murmac and Sun Dog projects, aiming to meet future supply demands with a focus on basement-hosted deposits.

As Forbes reported on October 11, the uranium market experienced renewed momentum after Russian President Vladimir Putin hinted at the possibility of a ban on uranium exports to Western nations. This suggestion "jolted the uranium market," which had been declining after peaking earlier in the year. The price of uranium rebounded to US$83.50 per pound, reflecting rising concerns about potential supply disruptions. Citi analysts noted that “Russia supplies close to 12% of U3O8, 25% of UF6, and 35% of EUP to international markets,” underscoring the challenges that Western nations, particularly the U.S. and Europe, could face in replacing these critical materials. This market dynamic positions uranium companies operating outside of Russia, like those in the Athabasca Basin, to benefit from supply gaps and heightened demand.

MSN reported on October 13 that the UK's nuclear power capacity is set to decrease dramatically in the coming years, with the planned closure of four out of five remaining nuclear plants by 2028. This reduction in capacity is expected to increase pressure on global uranium supplies as demand for nuclear energy continues to rise amid efforts to meet climate goals. The ongoing shift toward low-carbon energy sources, coupled with the planned closures, could create further supply constraints and drive demand for uranium from alternative sources.

Aero's Catalysts

According to the company's October 2024 investor presentation, the ongoing development at Murmac and Sun Dog highlights Aero Energy's strategy to enhance shareholder value by targeting high-grade uranium deposits in underexplored regions. Aero has leveraged recent technology investments, including VTEM Plus aerial surveys, which identified graphite-rich formations favorable for uranium. The exploration efforts build on the CA$7.6 million previously invested by project partners Fortune Bay and Standard Uranium, which has contributed to refining the drill targets. As Aero works with its partners to maximize the impact of this winter's drilling program, the company's strategic location on the north rim of the Athabasca Basin positions it well to expand these discoveries and attract continued investor interest.

The recently announced CA$2.5 million private placement will further strengthen Aero's financial capacity to carry out its targeted drill campaigns and exploration work.

Analyzing Aero

Jeff Clark of The Gold Advisor, in his October 17 update, noted that Aero Energy has "identified more than 70 kilometers of strike to test for high-grade basement-hosted uranium," emphasizing the company's significant exploration potential in a region known for some of the world's richest uranium deposits.

Clark further commented on Aero Energy's recent results, underscoring the importance of drill hole M24-017, which intersected 8.4 meters of uranium mineralization, grading 0.3% U3O8, with assays reaching as high as 13.8% U3O8. He stated, "While not a discovery hole, per se, this hole underscores the company's thesis that these two projects are prospective for the same type of uranium mineralization as Arrow and Triple R." This observation reinforces Aero Energy's exploration model, which targets basement-hosted uranium deposits similar to those found at other significant Athabasca Basin discoveries. [OWNERSHIP_CHART-11173]

Additionally, Clark expressed optimism regarding Aero Energy's current valuation and future prospects, recommending it as a strong buy at current levels. He highlighted his continued confidence in the company by stating, "I remain overweight the stock," suggesting that Aero Energy presents a compelling opportunity for speculative investors in the uranium exploration space.

The recently announced CA$2.5 million private placement was also acknowledged by Clark as a necessary step to fund further exploration activities. While he expressed some caution about potential dilution, he affirmed his overall support for the financing, noting that "its projects are very much worthy of follow-up."

Ownership and Share Structure

According to Refinitiv, management and insiders own 3.11% of Aero Energy. Of those, CEO Galen McNamara has the most at 2.97%. Institutions owns 4.79% with MMCAP Asset Management holding 3.89%. The rest is retail.

Aero has 92.3 million free float shares and a market cap of CA$4.5 million. The 52 week range is CA$0.040–$0.26.

Off-Ramp began eleven years ago, just as digital technology was beginning to overtake radio. No more cassette tape or mini-discs; host John and producer Queena Kim thought they could take on all of Los Angeles with two digital audio recorders and a different approach to public radio.

Short-handed as they were, John and Queena had to adopt slash-and-burn tactics to get each show produced on time. The majority of interviews were conducted in the field; at the homes, workplaces, and favorite hang-outs of their subjects (instead of waiting for guests to come to the station) and many of the stories were edited as simple two-way interviews with life in Southern California picked up as ambient, background noise. After all, a show called Off-Ramp had better be ready to brave some LA traffic.

At this juncture, John feels free to say what he has always wanted to, but hasn't for fear of self-aggrandizement: "I think we were trendsetters. I think Marketplace and NPR heard the stuff we were doing, and started doing stuff like it." Once again, Kim chalks it up to being in the right place at the right time technologically, and the two person team's willingness to break out of the old-school, public radio way writing a story: with a very clear sonic difference between studio narration and field audio.

Of course, it wasn't just Marantz recorders and minimal rewriting that gave Off-Ramp its flavor. There was a whole lot of weird spewing up out of Los Angeles during the show's formative years and Kim's tenure (2006-2010). She recalls covering a ten-theremin orchestra at Disney Hall, and the excitement of working on a show that let her (and the listeners, vicariously) do things she always wanted to do. "It was almost like having a free pass to the city."

In order to capture what was new and exciting, John and Queena both agree that it was absolutely vital to abandon the reporter's instinct for safely packaging the story ahead of time. John cites his editor at Minnesota Public Radio's philosophy, Mike Edgerly; "Go find what the story is, go out and explore and figure out what the story is. Don't figure it out at your desk first." The collaboration between John's ideas and Kim's sense of logistics formed a dialectic relationship, valuing the "third, better idea" over either of their original perspectives. In light of that, John says Queena Kim was the perfect person with whom to start Off-Ramp.

Maya more warlike than previously thought

Full Text:

The Maya of Central America are thought to have been a kinder, gentler civilization, especially compared to the Aztecs of Mexico. At the peak of Mayan culture some 1,500 years ago, warfare seemed ritualistic, designed to extort ransom for captive royalty or to subjugate rival dynasties, with limited impact on the surrounding population. Only later, archeologists thought, did increasing drought and climate change lead to total warfare -- cities and dynasties were wiped off the map in so-called termination events -- and the collapse of the lowland Maya civilization around 1,000 A.D. (or C.E., current era). New evidence unearthed by National Science Foundation-funded researchers call all this into question, suggesting that the Maya engaged in scorched-earth military campaigns -- a strategy that aims to destroy anything of use, including cropland -- even at the height of their civilization, a time of prosperity and artistic sophistication. The finding also indicates that this increase in warfare, possibly associated with climate change and resource scarcity, was not the cause of the disintegration of the lowland Maya civilization.

Virtual 'UniverseMachine' sheds light on galaxy evolution

Full Text:

How do galaxies such as our Milky Way come into existence? How do they grow and change over time? The science behind galaxy formation has long been a puzzle, but a University of Arizona-led team of scientists is one step closer to finding answers, thanks to supercomputer simulations. Observing real galaxies in space can only provide snapshots in time, so researchers who study how galaxies evolve over billions of years need to use computer simulations. Traditionally, astronomers have used simulations to invent theories of galaxy formation and test them, but they have had to proceed one galaxy at a time. Peter Behroozi of the university's Steward Observatory and colleagues overcame this hurdle by generating millions of different universes on a supercomputer, each according to different physical theories for how galaxies form. The findings challenge fundamental ideas about the role dark matter plays in galaxy formation, the evolution of galaxies over time and the birth of stars. The study is the first to create self-consistent universes that are exact replicas of the real ones -- computer simulations that each represent a sizeable chunk of the actual cosmos, containing 12 million galaxies and spanning the time from 400 million years after the Big Bang to the present day. The results from the "UniverseMachine," as the authors call their approach, have helped resolve the long-standing paradox of why galaxies cease to form new stars even when they retain plenty of hydrogen gas, the raw material from which stars are forged. The research is partially funded by NSF's Division of Physics through grants to UC Santa Barbara's Kavli Institute for Theoretical Physics and the Aspen Center for Physics.

Silver Co. Releases High-Grade Results From Golden Triangle Drilling

Source: Streetwise Reports 11/05/2024

Dolly Varden Silver Corp. (DV:TSX.V; DOLLF:OTCQX) releases new results from its 2024 drilling program at its Kitsault Valley project in British Columbia's Golden Triangle. One analyst says the company is an "attractive target" for large precious metal producers.

Dolly Varden Silver Corp. (DV:TSX.V; DOLLF:OTCQX) released results from five drill holes from its completed 2024 drilling program at its Kitsault Valley project in British Columbia's Golden Triangle.

In total, the program drilled 69 holes for 31,726 meters — 41 holes totaling more than 15,000 meters at the Dolly Varden area and 28 holes totaling more than 16,000 meters at Homestake Ridge.

Highlights of Monday's release include one hole from the Homestake Silver Deposit that found 12.23 grams per tonne gold (g/t Au) and 84 g/t silver (Ag) over 34.93 meters with high-grade breccia veins that included 166 g/t Au and 675 g/t Ag over 0.97 meters.

"The identification of a gold-rich, wide and high-grade area within the Homestake Silver Deposit is highly encouraging," said Chief Executive Officer Shawn Khunkhun. "Our geological team is encouraged by overlapping mineralizing phases of silver and gold-rich veins and breccias; the deposit remains open for expansion."

Technical Analyst Clive Maund, writing on Sunday, called Dolly Varden "one of the best pure silver companies around."

The stock's "breakout at end of last month/early this month was on big volume means it was genuine," Maund wrote.

The stock is at a "classic buy spot, although we should remain aware that it could zigzag a little lower over the short-term, but that said it looks like a strong buy here."

Highlights From Results

Highlights from the Homestake Silver Deposit include:

  • Hole HR24-432: Mineralized envelope including veins: 8.85 g/t Au and 5 g/t Ag over 48.23 meters, including an internal zone of stronger breccia vein intervals grading 29.24 g/t Au and 16 g/t Ag over 13.94 meters, including one breccia vein grading 701 g/t Au and 184 g/t Ag over 0.54 meters.
  • Hole HR24-435: Mineralized envelope including veins: 4.64 g/t Au and 38 g/t Ag over 100.80 meters, including an internal interval of stronger breccia vein mineralization grading 12.23 g/t Au and 84 g/t Ag over 34.93 meters. High-grade breccia veins include 166 g/t Au and 675 g/t Ag over 0.97 meters.
  • Hole HR24-442: Vein breccia zone: 4.58 g/t Au over 9.95 meters, including 14.96 g/t Au over 1.69 meters.

"Results from the five holes in this release suggest that the plunge of mineralization at Homestake Silver has a similar orientation as the Homestake Main Deposit, located 300 meters to the northwest," the company said in a release. "The average grades within these core areas are higher, on a precious metal silver equivalent basis, than the average grade of the silver deposits at the Dolly Varden property further south, due to the increased gold content at the Homestake Ridge Deposits."

Technical Analyst Clive Maund, writing on Sunday, called Dolly Varden "one of the best pure silver companies around."

Drill holes HR24-442 and HR24-445 are step-outs and encountered the mineralized and altered structural corridor of Homestake Silver, the company said. Drill hole HR24-442 intersected a mineralized vein breccia stockwork zone grading 4.58 g/t Au over 9.95 meters, including individual breccias with stronger pyrite mineralization grading 14.96 g/t Au over 1.69 meters.

The Homestake Ridge deposits are interpreted as structurally controlled, multi-phase epithermal vein stockwork and vein breccia system hosted in Jurassic Hazelton volcanic rocks, Dolly Varden noted. Mineralization consists of pyrite plus galena and sphalerite with visible gold in a breccia matrix within a silica breccia vein system.

"The northwest orientation of the main Homestake structural trend appears to have numerous subparallel internal structures that are interpreted to form the controls for higher grade gold and silver shoots within a broader mineralized envelope at the Homestake Silver deposit," the company said. "The main structural corridor dips steeply to the northeast at Homestake Main and rolls to vertical or steeply southwest at Homestake Silver."

Analyst's Response: 'Boom'

Jeff Valks, Senior Analyst for The Gold Advisor newsletter, reacted to the results with the word "BOOM."

"Dolly Varden Silver reports more high-grade drill results from its 2024 exploration program at the Homestake Silver Deposit in British Columbia's Golden Triangle," he wrote on Monday. "Results from five drill holes have confirmed significant gold and silver mineralization in an area targeted within the plunge of a previously undrilled high-grade zone, signaling potential expansion opportunities."

Jeff Valks, Senior Analyst for The Gold Advisor newsletter, reacted to the results with the word "BOOM."

We look forward to the remaining results." Vaks wrote. "In the meantime, the stock is flat as I write but is up over 35% year-to-date. It's not too late to buy, it's down from its recent spike, and as (editor) Jeff (Clark) has said, this is a core holding for the silver bull market. Use a stink bid if you're looking for shares. Both Jeff and I hold long positions."

Analyst Marcus Giannini of Haywood Capital Markets noted in a recent research note that Dolly Varden continues to "push the margins of known high-grade mineralization" at the project.

Gianini gave the stock a Buy rating with a CA$2.40 per share target price. "We continue to view Dolly's high-grade endowment as an increasingly attractive target for larger North American-focused precious metal producers," he noted.

The Catalyst: Analysts Point to Patience

While it has chased the record highs gold has been setting this year, silver recently broke through US$35 per ounce, reflecting a year-to-date gain of about 47%. It has since settled but held to the "crucial US$32.50 level," according to Christopher Lewis of FX Empire on Monday.

"Keep in mind that this is a market that is extraordinarily volatile and, of course, will continue to be noisy over the next couple of days as we get election results in the United States," Lewis wrote. "And of course, we also get the Federal Reserve interest rate decision on Thursday, both of which could cause chaos."

Lewis said he thinks the "least likely path is lower."

"I still favor an upside move, but I recognize that we are definitely in a little bit of a holding pattern," he wrote. "Having said that, if we do see momentum to the upside, then there's really not a whole lot here that could keep this market from trying to challenge the (US$)35 level again, obviously, a large round psychologically significant figure, but we'll just have to wait and see how that plays out."

The most conductive element in nature, silver is used to coat electrical contacts in computers, phones, cars, and appliances. It's also an important element in solar technology.

Mordor Intelligence noted that the white metal is expected to register a compound annual growth rate (CAGR) of more than 5% between 2024 and 2029.

Newsletter editor Brien Lundin encouraged investors not to get discouraged, as any price drop-off is temporary, he said. He expects the silver price to soar when the U.S. Federal Reserve doubles down on its efforts to get interest rates much lower, he wrote on Oct. 23. [OWNERSHIP_CHART-5439]

Based on silver's charts, Ron Struthers of Struthers Resource Stock Report also predicted a major run-up in the silver price.

"Back in April or early May, I highlighted the breakout from a cup and handle formation and [that] that would lead to a major upside move. This is now confirmed," he wrote on Oct. 23.

Ownership and Share Structure

According to the company's latest corporate presentation, 50% of its stock is held by institutional investors, including Fidelity Management & Research Company LLC, Sprott Asset Management LP, U.S. Global Investors Inc., and Delbrook.

About 41% is with strategic investors, including 17% with Fury Gold Mines, 14% with Hecla, and Eric Sprott owns 10% himself.

Drill Program Targets High-Grade Gold Veins in British Columbia

Source: Streetwise Reports 11/06/2024

Independence Group NL (IGO:ASX) has begun a comprehensive diamond drill program at its fully-owned 3Ts Project, located in British Columbia.Read more about the 25 planned drill holes aimed at unlocking high-grade intercepts and the promising exploration targets at the 3Ts Project.

Independence Gold Corp. (IGO:TSX.V; IEGCF:OTCMKTS) has begun a comprehensive diamond drill program at its fully-owned 3Ts Project, located in British Columbia. Positioned 16 km from Artemis Gold Inc.'s Blackwater Project, the 3Ts Project covers 8,840 hectares within a prolific epithermal quartz-carbonate vein district on the Nechako Plateau. The program will consist of approximately 25 drill holes, totaling a minimum of 7,500 meters. The targets are the Ted-Mint and Tommy Vein Systems, with a primary emphasis on unexplored depth zones to identify high-grade intercepts for mineral resource expansion.

The 3Ts Project encompasses multiple identified veins, with strike lengths from 50 to over 1,100 meters and true widths of up to 25 meters. Additional exploration will be directed at the Ian, Johnny, and Larry Veins, focusing on mineralization both along strike and at depth. The Ootsa and Balrog targets, identified through geophysical and geological data collected during the summer 2024 exploration program, are also set to undergo further investigation.

President and CEO Randy Turner stated in the press release, "We look forward to building on the success of recent drill programs at 3Ts. With a larger and more extensive drill program planned, including deeper holes to test the major vein systems below the microdiorite sill and further testing of the newly discovered Ootsa and Balrog targets, we anticipate a very busy and exciting year ahead."

Upon hearing this news, Jeff Clark of The Gold Advisor wrote, "And they're off! This is the THIRD drill program this year at 3Ts, an aggressive schedule that, as investors, we're very happy to see."

He noted that these results will help expand the current resource. He continued, "Remember, management just raised a whopping US$6.65 million, more than double the initial goal, due to strong investor interest. They thus have the financial firepower to conduct all this drilling before winter sets in. The stock isn't reacting to the news, but this isn't something that would normally have a big impact on it. It's cooled from its recent spike so offers a very attractive entry point if you don't have the shares you want. This is an overweight position for me, and it's my belief we'll see more spikes just like the one we witnessed. More news and potential catalysts ahead. This is definitely one to own for the gold bull market."

Looking Into Gold

On October 29, Kitco reported that gold prices approached US$2,800. This reflects a substantial 35% increase for the year. According to the report, this growth resulted from multiple factors, including geopolitical conflicts, Federal Reserve interest rate normalization, strong central bank demand, and political uncertainties surrounding the upcoming presidential election. Analysts described these elements as a "perfect storm," which significantly bolstered investor sentiment and reinforced gold's appeal as a hedge against economic instability.

"This is definitely one to own for the gold bull market," Jeff Clark of The Gold Advisor Wrote.

LiveMint, on October 30, noted the strong performance of precious metals, emphasizing that silver had outpaced gold over the past year. Ankit Gohel from LiveMint mentioned, "Gold has delivered a substantial return of over 33.5% since Dhanteras last year," but highlighted that silver had achieved an even more impressive rally of over 40.5%. Despite this, gold continued to attract attention, with Chintan Mehta, CEO of Abans Holdings, emphasizing gold's role as a safe haven during times of uncertainty. He said, "Gold stands out in times of uncertainty . . . It's a complete safe-haven unlike silver, which always has that industrial component attached to it, adding an extra layer of risk."

In a November 4 article, Egon von Greyerz of Matterhorn Asset Management provided a historical perspective on gold's consistent role in preserving wealth. Von Greyerz discussed how gold had risen 78 times since 1971, when the dollar lost its gold backing, emphasizing that "gold held in the investor's name in safe vaults and jurisdictions outside the financial system is the ultimate form of wealth preservation." He argued that gold's ascent had only just begun, driven by the devaluation of fiat currencies and ongoing global debt expansion.

Independence Catalysts

According to the company's September 2024 investor presentation, the 3Ts Project remains a high-priority asset with substantial growth potential. The updated NI 43-101 compliant resource estimate for the Tommy, Ted, and Mint veins, totaling 522,330 ounces of gold and 13.83 million ounces of silver, is expected to expand with new discoveries and continued drilling. Recent metallurgical testing has returned gold recoveries of up to 97.9%, and the strategic location near Artemis Gold's Blackwater Mine adds further credibility to the project's prospects. [OWNERSHIP_CHART-7643]

The fall 2024 drill program, with a budget of CA$4.5 million, will test high-grade zones and underexplored targets, building on over 63,000 meters of historical drilling. Additionally, new targets such as the Balrog and Ootsa anomalies present significant exploration upside, underscoring the project's potential for resource expansion and discovery.

Ownership and Share Structure

According to Refinitiv, about 4.38% of the company is held by insiders and management.

7.97% is with strategic investor Newmont Corp.

The rest is retail.

Its market cap is CA$29.28 million with 167.8 million shares outstanding. It trades in a 52-week range of CA$0.34 and CA$0.12.

CDC Extends Eviction Moratorium Through July

Pam Fessler | NPR

The Centers for Disease Control and Prevention has extended a moratorium on evictions until the end of July. The ban had been set to expire next week, raising concerns that there could be a flood of evictions with some seven million tenants currently behind on their rent.

The Biden administration says the extension is for "one final month" and will allow time for it to take other steps to stabilize housing for those facing eviction and foreclosure. The White House says it is encouraging state and local courts to adopt anti-eviction diversion programs to help delinquent tenants stay housed and avoid legal action.

The federal government will also try to speed up distribution of tens of billions of dollars in emergency rental assistance that's available but has yet to be spent. In addition, a moratorium on foreclosures involving federally backed mortgages has been extended for "a final month," until July 31.

In announcing the extension of the eviction moratorium, the CDC said that the COVID-19 "pandemic has presented a historic threat to the nation's public health. Keeping people in their homes and out of crowded or congregate settings — like homeless shelters — by preventing evictions is a key step in helping to stop the spread of COVID-19."

The CDC first issued the moratorium last September. It was extended once already in March, until June 30.

But landlords have been pushing back, arguing that they've taken a huge financial hit over the past year, losing billions of dollars a month in rent. Several business groups have sued the CDC and won, though court decisions to lift the moratorium have been stayed pending appeal.

The Alabama Association of Realtors, which brought one of the cases, argued that the CDC exceeded its authority in issuing the ban. The group is seeking relief from the U.S. Supreme Court, but the justices have yet to respond.

In its petition, the Realtors association called the CDC's "continued insistence that public-health concerns necessitate that landlords continue to provide free housing for tenants who have received vaccines (or passed up the chance to get them)...sheer doublespeak."

Housing advocates have argued that the moratorium is still very much needed. They note that $46 billion in emergency rental assistance approved by Congress has been slow getting into the hands of those it was intended to help. The money is supposed to cover rent that tenants currently owe.

The National Low Income Housing Coalition reports that in some states, less than five percent of the funds have been distributed so far. The group pushed the administration to extend the ban to give states and localities more time to get the money out.

Despite the moratorium, thousands of renters have still faced the threat of eviction because of loopholes in the law. Many are the lowest income tenants and disproportionately people of color. A new study by the Eviction Lab at Princeton University has found that communities with the lowest vaccination rates tend to have the highest eviction filings, raising additional health concerns.

"Allowing the moratorium to expire before vaccination rates increase in marginalized communities could lead to increased spread of, and deaths from, COVID-19," a group of more than 40 House lawmakers wrote in a letter this week to President Biden and CDC Director Rochelle Walensky, urging them to extend the moratorium.

He Inherited A Devastating Disease. A CRISPR Gene-Editing Breakthrough Stopped It

Patrick Doherty volunteered for a new medical intervention of gene-editor infusions for the treatment of genetically-based diseases.; Credit: /Patrick Doherty

Rob Stein | NPR

Patrick Doherty had always been very active. He trekked the Himalayas and hiked trails in Spain.

But about a year and a half ago, he noticed pins and needles in his fingers and toes. His feet got cold. And then he started getting out of breath any time he walked his dog up the hills of County Donegal in Ireland where he lives.

"I noticed on some of the larger hill climbs I was getting a bit breathless," says Doherty, 65. "So I realized something was wrong."

Doherty found out he had a rare, but devastating inherited disease — known as transthyretin amyloidosis — that had killed his father. A misshapen protein was building up in his body, destroying important tissues, such as nerves in his hands and feet and his heart.

Doherty had watched others get crippled and die difficult deaths from amyloidosis.

"It's terrible prognosis," Doherty says. "This is a condition that deteriorates very rapidly. It's just dreadful."

So Doherty was thrilled when he found out that doctors were testing a new way to try to treat amyloidosis. The approach used a revolutionary gene-editing technique called CRISPR, which allows scientists to make very precise changes in DNA.

"I thought: Fantastic. I jumped at the opportunity," Doherty says.

On Saturday, researchers reported the first data indicating that the experimental treatment worked, causing levels of the destructive protein to plummet in Doherty's body and the bodies of five other patients treated with the approach.

"I feel fantastic," Doherty says. "It's just phenomenal."

The advance is being hailed not just for amyloidosis patients but also as a proof-of-concept that CRISPR could be used to treat many other, much more common diseases. It's a new way of using the innovative technology.

"This is a major milestone for patients," says Jennifer Doudna of the University of California, Berkeley, who shared a Nobel Prize for her work helping develop CRISPR.

"While these are early data, they show us that we can overcome one of the biggest challenges with applying CRISPR clinically so far, which is being able to deliver it systemically and get it to the right place," Doudna says.

CRISPR has already been shown to help patients suffering from the devastating blood disorders sickle cell disease and beta thalassemia. And doctors are trying to use it to treat cancer and to restore vision to people blinded by a rare genetic disorder.

But those experiments involve taking cells out of the body, editing them in the lab, and infusing them back in or injecting CRISPR directly into cells that need fixing.

The study Doherty volunteered for is the first in which doctors are simply infusing the gene-editor directly into patients and letting it find its own way to the right gene in the right cells. In this case, it's cells in the liver making the destructive protein.

"This is the first example in which CRISPR-Cas9 is injected directly into the bloodstream — in other words systemic administration — where we use it as a way to reach a tissue that's far away from the site of injection and very specifically use it to edit disease-causing genes," says John Leonard, the CEO of Intellia Therapeutics, which is sponsoring the study.

Doctors infused billions of microscopic structures known as nanoparticles carrying genetic instructions for the CRISPR gene-editor into four patients in London and two in New Zealand. The nanoparticles were absorbed by their livers, where they unleashed armies of CRISPR gene-editors. The CRISPR editor honed in on the target gene in the liver and sliced it, disabling production of the destructive protein.

Within weeks, the levels of protein causing the disease plummeted. Researchers reported at the Peripheral Nerve Society Annual Meeting and in a paper published in The New England Journal of Medicine.

"It really is exciting," says Dr. Julian Gillmore, who is leading the study at the University College London, Royal Free Hospital.

"This has the potential to completely revolutionize the outcome for these patients who have lived with this disease in their family for many generations. It's decimated some families that I've been looking after. So this is amazing," Gillmore says.

The patients will have to be followed longer, and more patients will have to be treated, to make sure the treatment's safe, and determine how much it's helping, Gillmore stresses. But the approach could help those struck by amyloidosis that isn't inherited, which is a far more common version of the disease, he says.

Moreover, the promising results potentially open the door for using the same approach to treatment of many other, more common diseases for which taking cells out of the body or directly injecting CRISPR isn't realistic, including heart disease, muscular dystrophy and brain diseases such as Alzheimer's.

"This is really opening a new era as we think about gene-editing where we can begin to think about accessing all kinds of different tissue in the body via systemic administration," Leonard says.

Other scientists who are not involved in the research agree.

"This is a wonderful day for the future of gene-editing as a medicine,"
agree Fyodor Urnov, a professor of genetics at the University of California, Berkeley. "We as a species are watching this remarkable new show called: our gene-edited future."

Doherty says he started feeling better within weeks of the treatment and has continued to improve in the weeks since then.

"I definitely feel better," he told NPR. "I'm speaking to you from upstairs in our house. I climbed stairs to get up here. I would have been feeling breathless. I'm thrilled."

A Hospital Charged More Than $700 For Each Push Of Medicine Through Her IV

; Credit: /Rose Wong for NPR/KHN

Rae Ellen Bichell | NPR

Claire Lang-Ree was in a lab coat taking a college chemistry class remotely in the kitchen of her Colorado Springs, Colo., home, when a profound pain twisted into her lower abdomen. She called her mom, Jen Lang-Ree, a nurse practitioner who worried it was appendicitis and found a nearby hospital in the family's health insurance network.

After a long wait in the emergency room of Penrose Hospital, Claire received morphine and an anti-nausea medication delivered through an IV. She also underwent a CT scan of her abdomen and a series of tests.

Hospital staffers ruled out appendicitis and surmised Claire was suffering from a ruptured ovarian cyst, which can be a harmless part of the menstrual cycle but can also be problematic and painful. After a few days — and a chemistry exam taken through gritted teeth — the pain went away.

Then the bill came.

Patient: Claire Lang-Ree, a 21-year-old Stanford University student who was living in Colorado for a few months while taking classes remotely. She's insured by Anthem Blue Cross through her mom's work as a pediatric nurse practitioner in Northern California.

Total Bill: $18,735.93, including two $722.50 fees for a nurse to "push" drugs into her IV, a process that takes seconds. Anthem's negotiated charges were $6,999 for the total treatment. Anthem paid $5,578.30, and the Lang-Rees owed $1,270.45 to the hospital, plus additional bills for radiologists and other care. (Claire also anted up a $150 copay at the ER.)

Service Provider: Penrose Hospital in Colorado Springs, part of the regional health care network Centura Health.

What Gives: As hospitals disaggregate charges for services once included in an ER visit, a hospitalization or a surgical procedure, there has been a proliferation of newfangled fees to increase billing. In the health field, this is called "unbundling." It's analogous to the airlines now charging extra for each checked bag or for an exit row seat. Over time, in the medical industry, this has led to separate fees for ever-smaller components of care. A charge to put medicine into a patient's IV line — a "push fee" — is one of them.

Though the biggest charge on Claire's bill, $9,885.73, was for a CT scan, in many ways Claire and her mom found the push fees most galling. (Note to readers: Scans are frequently many times more expensive when ordered in an ER than in other settings.)

"That was so ridiculous," says Claire, who adds she had previously taken the anti-nausea drug they gave her; it's available in tablet form for the price of a cup of coffee, no IV necessary. "It works really well. Why wasn't that an option?"

In Colorado, the average charge for the code corresponding to Claire's first IV push has nearly tripled since 2014, and the dollars hospitals actually get for the procedure has doubled. In Colorado Springs specifically, the cost for IV pushes rose even more sharply than it did statewide.

A typical nurse in Colorado Springs makes about $35 an hour. At that rate, it would take nearly 21 hours to earn the amount of money Penrose charged for a push of plunger that likely took seconds or at most minutes.

The hospital's charge for just one "IV push" was more than Claire's portion of the monthly rent in the home she shared with roommates. In the end, Anthem did not pay the push fees in its negotiated payment. But claims data shows that in 2020 Penrose typically received upward of $1,000 for the first IV push. And patients who didn't have an insurer to dismiss such charges would be stuck with them. Colorado hospitals on average received $723 for the same code, according to the claims database.

"It's insane the variation that we see in prices, and there's no rhyme or reason," says Cari Frank with the Center for Improving Value in Health Care, a Colorado nonprofit that runs a statewide health care claims database. "It's just that they've been able to negotiate those prices with the insurance company and the insurance company has decided to pay it."

To put the total cost in context, Penrose initially charged more money for Claire's visit than the typical Colorado hospital would have charged for helping someone give birth, according to data published by the Colorado Division of Insurance.

Even with the negotiated rate, "it was only $1,000 less than an average payment for having a baby," Frank says.

In an email statement, Centura said it "conducted a thorough review and determined all charges were accurate" and went on to explain that "an Emergency Room (ER) must be prepared for anything and everything that comes through the doors," requiring highly trained staff, plus equipment and supplies. "All of this adds up to large operating costs and can translate into patient responsibility."

As researchers have found, little stands in the way of hospitals charging through the roof, especially in a place like an emergency room, where a patient has few choices. A report from National Nurses United found that hospital markups have more than doubled since 1999, according to data from the United States Bureau of Labor Statistics. In an email, Anthem called the trend of increasing hospital prices "alarming" and "unsustainable."

But Ge Bai, an associate professor of accounting and health policy at Johns Hopkins University, says when patients see big bills it isn't only the hospital's doing — a lot depends on the insurer, too. For one, the negotiated price depends on the negotiating power of the payer, in this case, Anthem.

"Most insurance companies don't have comparable negotiating or bargaining power with the hospital," said Bai. Prices in a state like Michigan, where Bai said the UAW union covers a big proportion of Michigan patients, will look very different from those in Colorado.

Also, insurers are not the wallet defenders patients might assume them to be.

"In many cases, insurance companies don't negotiate as aggressively as they can, because they earn profit from the percentage of the claims," she says. The more expensive the actual payment is, the more money they get to extract.

Though Anthem negotiated away the push fees, it paid the hospital 30% more than the average Level IV emergency department visit in Colorado that year, and it paid quadruple what Medicare would allow for her CT scan.

Resolution: Claire and her mom decided to fight the bill, writing letters to the hospital and searching for information on what the procedures should have cost. The cost of the IV pushes and CT scan infuriated them — the hospital wanted more than double for a CT than what top-rated hospitals typically charged in 2019.

But the threat of collections wore them out and ultimately they paid their assigned share of the bill — $1,420.45, which was mostly coinsurance.

"Eventually it got to the point where I was like, 'I don't really want to go to collections, because this might ruin my credit score,'" says Claire, who didn't want to graduate from college with dinged credit.

Bai and Frank say the state of Maryland can provide a useful benchmark for medical bills, since it sets the prices that hospitals can charge for each procedure. Data provided by the Maryland Health Care Commission shows that Anthem and Claire paid seven times what she likely would have paid for the CT scan there, and nearly 10 times what they likely would have paid for the emergency department Level IV visit. In Maryland, intravenous pushes typically cost about $200 apiece in 2019. A typical Maryland hospital would have received only about $1,350 from a visit like Claire's, and the Lang-Rees would have been on the hook for about $270.

Claire's pain has come back a few times, but never as bad as that night in Colorado. She has avoided reentering an emergency room since then. After visiting multiple specialists back home in California, she learned she might have had a condition called ovarian torsion.

The Takeaway: Even at an in-network facility and with good insurance, patients can get hurt financially by visiting the ER. A few helpful documents can help guide the way to fighting such charges. The first is an itemized bill.

"I just think it's wrong in the U.S. to charge so much," says Jen Lang-Ree. "It's just a little side passion of mine to look at those and make sure I'm not being scammed."

Bai, of Johns Hopkins, suggests asking for an itemized explanation of benefits from the insurance company, too. That will show what the hospital actually received for each procedure.

Find out if the hospital massively overcharged. The Medicare price lookup tool can be useful for getting a benchmark. And publicly available data on health claims in Colorado and at least 17 other states can help, too.

Vincent Plymell with the Colorado Division of Insurance encourages patients to reach out if something on a bill looks sketchy. "Even if it's not a plan we regulate," he wrote in an email, departments such as his "can always arm the consumer with info."

Finally, make scrutinizing such charges fun. Claire and Jen made bill-fighting their mother-daughter hobby for the winter. They recommend pretzel chips and cocktails to boost the mood.

New Book Details Full History Of Black Baseball Players’ Fight For Integration

Copy of the book “Beyond Baseball’s Color Barrier: The Story of African Americans in Major League Baseball, Past, Present, and Future” (Rowman & Littlefield, May 2021)

AirTalk

Most of us are familiar with the story of Jackie Robinson, the first Black player to play baseball in the Major Leagues, and while Jackie’s story is arguably the biggest chapter in the story of how baseball was integrated, there’s plenty more to the story that happened both before and after Jackie broke into the Majors. Author, sports historian and Santa Barbara City College Director of Athletics Rocco Constantino dives into this rich history in his new book “Beyond Baseball’s Color Barrier: The Story of African Americans in Major League Baseball, Past, Present, and Future” where he explores the contributions of major figures like Hank Aaron, Willie Mays and Satchel Paige as well as the lesser known ones of players like Vida Blue, Mudcat Grant and Dwight Gooden.

Today on AirTalk, Constantino joins Larry Mantle to explore the history of Black players in baseball, their fight for recognition and integration into the Major Leagues and the issues of race that persisted well beyond Jackie Robinson breaking baseball’s color barrier.

Guest:

Rocco Constantino, author of “Beyond Baseball’s Color Barrier: The Story of African Americans in Major League Baseball, Past, Present, and Future” (Rowman & Littlefield, May 2021); he is a sports historian and the director of athletics at Santa Barbara City College
