The structures of five ammonium salt forms of mono­sulfonated azo dyes, derivatives of 4-(2-phenyldiazen-1-yl)benzenesulfonate, with the general formula [NH4][O3S(C6H4)NN(C6H3)RR']·XH2O [R = OH, NH2 or N(C2H4OH)2; R' = H or OH] are presented. All form simple layered structures with alternating hydro­phobic (organic) and hydro­philic (cation, solvent and polar groups) layers. To assess for isostructural behaviour of the ammonium cation with M+ ions, the packing of these structures is compared with literature examples. To aid this comparison, the corresponding structures of four potassium salt forms of the mono­sulfonated azo dyes are also presented herein. Of the five ammonium salts it is found that three have isostructural equivalents. In two cases this equivalent is a potassium salt form and in one case it is a rubidium salt form. The isostructurality of ion packing and of unit-cell symmetry and dimensions tolerates cases where the ammonium ions form somewhat different inter­action types with coformer species than do the potassium or rubidium ions. No sodium salt forms are found to be isostructural with any ammonium equivalent. However, similarities in the anion packing within a single hydro­phobic layer are found for a group that consists of the ammonium and rubidium salt forms of one azo anion species and the sodium and silver salt forms of a different azo species.

Cryo-electron tomography (cryo-ET) enables molecular-resolution 3D imaging of complex biological specimens such as viral particles, cellular sections and, in some cases, whole cells. This enables the structural characterization of molecules in their near-native environments, without the need for purification or separation, thereby preserving biological information such as conformational states and spatial relationships between different molecular species. Subtomogram averaging is an image-processing workflow that allows users to leverage cryo-ET data to identify and localize target molecules, determine high-resolution structures of repeating molecular species and classify different conformational states. Here, STOPGAP, an open-source package for subtomogram averaging that is designed to provide users with fine control over each of these steps, is described. In providing detailed descriptions of the image-processing algorithms that STOPGAP uses, this manuscript is also intended to serve as a technical resource to users as well as for further community-driven software development.

Molecular structures can be determined in vitro and in situ with cryo-electron microscopy (cryo-EM). Specimen preparation is a major obstacle in cryo-EM. Typical sample preparation is orders of magnitude slower than biological processes. Time-resolved cryo-EM (TR-cryo-EM) can capture short-lived states. Here, Cryo-EM sample preparation with light-activated molecules (C-SPAM) is presented, an open-source, photochemistry-coupled device for TR-cryo-EM that enables millisecond resolution and tunable timescales across broad biological applications.

X-ray free-electron laser (XFEL) light sources have enabled the rapid growth of time-resolved structural experiments, which provide crucial information on the function of macromolecules and their mechanisms. Here, the aim was to commission the SwissMX fixed-target sample-delivery system at the SwissFEL Cristallina experimental station using the PSI-developed micro-structured polymer (MISP) chip for pump–probe time-resolved experiments. To characterize the system, crystals of the light-sensitive protein light–oxygen–voltage domain 1 (LOV1) from Chlamydomonas reinhardtii were used. Using different experimental settings, the accidental illumination, referred to as light contamination, of crystals mounted in wells adjacent to those illuminated by the pump laser was examined. It was crucial to control the light scattering from and through the solid supports otherwise significant contamination occurred. However, the results here show that the opaque MISP chips are suitable for defined pump–probe studies of a light-sensitive protein. The experiment also probed the sub-millisecond structural dynamics of LOV1 and indicated that at Δt = 10 µs a covalent thio­ether bond is established between reactive Cys57 and its flavin mononucleotide cofactor. This experiment validates the crystals to be suitable for in-depth follow-up studies of this still poorly understood signal-transduction mechanism. Importantly, the fixed-target delivery system also permitted a tenfold reduction in protein sample consumption compared with the more common high-viscosity extrusion-based delivery system. This development creates the prospect of an increase in XFEL project throughput for the field.

A significant part of the present and future of optoelectronic devices lies on thin multilayer heterostructures. Their optical properties depend strongly on strain, being essential to the knowledge of the stress level to optimize the growth process. Here the structural and microstructural characteristics of sub-micron a-ZnO epilayers (12 to 770 nm) grown on r-sapphire by metal–organic chemical vapour deposition are studied. Morphological and structural studies have been made using scanning electron microscopy and high-resolution X-ray diffraction. Plastic unit-cell distortion and corresponding strain have been determined as a function of film thickness. A critical thickness has been observed as separating the non-elastic/elastic states with an experimental value of 150–200 nm. This behaviour has been confirmed from ultraviolet photoelectron spectroscopy, X-ray photoelectron spectroscopy and high-resolution transmission electron microscopy measurements. An equation that gives the balance of strains is proposed as an interesting method to experimentally determine this critical thickness. It is concluded that in the thinnest films an elongation of the Zn—O bond takes place and that the plastic strained ZnO films relax through nucleation of misfit dislocations, which is a consequence of three-dimensional surface morphology.

The structures of fourteen halochalcogenyl­phospho­nium tetra­halogen­ido­aurates(III), phosphane chalcogenide derivatives with general formula [R13–nR2nPEX][AuX4] (R1 = t-butyl; R2 = isopropyl; n = 0 to 3; E = S or Se; X = Cl or Br) are presented. The eight possible chlorido derivatives are: 17a, n = 3, E = S; 18a, n = 2, E = S; 19a, n = 1, E = S; 20a, n = 0, E = S; 21a, n = 3, E = Se; 22a, n = 2, E = Se; 23a, n = 1, E = Se; and 24a, n = 0, E = Se, and the corresponding bromido derivatives are 17b–24b in the same order. Structures were obtained for all compounds except for the tri-t-butyl derivatives 24a and 24b. Isotypy is observed for 18a/18b/22a/22b, 19a/23a, 17b/21b and 19b/23b. In eleven of the compounds, X⋯X contacts (mostly very short) are observed between the cation and anion, whereby the E—X⋯X groups are approximately linear and the X⋯X—Au angles approximately 90°. The exceptions are 17a, 19a and 23a, which instead display short E⋯X contacts. Bond lengths in the cations correspond to single bonds P—E and E—X. For each group with constant E and X, the P—E—X bond-angle values increase monotonically with the steric bulk of the alkyl groups. The packing is analysed in terms of E⋯X, X⋯X (some between anions alone), H⋯X and H⋯Au contacts. Even for isotypic compounds, some significant differences can be discerned.

Bis(2-methyl­pyridine)­gold(I) di­bromido­aurate(I), [Au(C6H7N)2][AuBr2], (1), crystallizes in space group C2/c with Z = 4. Both gold atoms lie on twofold axes and are connected by an aurophilic contact. A second aurophilic contact leads to infinite chains of alternating cations and anions parallel to the b axis, and the residues are further connected by a short H⋯Au contact and a borderline Br⋯Br contact. Bis(3-methyl­pyridine)­gold(I) di­bromido­aurate(I), [Au(C6H7N)2][AuBr2], (2), crystallizes in space group C2/m with Z = 2. Both gold atoms lie on special positions with symmetry 2/m and are connected by an aurophilic contact; all other atoms except for one methyl hydrogen lie in mirror planes. The extended structure is closely analogous to that of 1, although the structures are formally not isotypic. Bis(3,5-di­methyl­pyridine)­gold(I) di­chlor­ido­aurate(I), [Au(C7H9N)2][AuCl2], (3) crystallizes in space group Poverline{1} with Z = 2. The cation lies on a general position, and there are two independent anions in which the gold atoms lie on inversion centres. The cation and one anion associate via three short H⋯Cl contacts to form a ribbon structure parallel to the b axis; aurophilic contacts link adjacent ribbons. Bis(3,5-di­methyl­pyridine)­gold(I) di­bromido­aurate(I), [Au(C7H9N)2][AuBr2], (4) is isotypic to 3. Attempts to make similar compounds involving 2-bromo­pyridine led instead to 2-bromopyridinium di­bromido­aurate(I)–2-bromo­pyridine (1/1), (C5H5BrN)[AuBr2]·C5H4BrN, (5), which crystallizes in space group Poverline{1} with Z = 2; all atoms lie on general positions. The 2-bromo­pyridinium cation is linked to the 2-bromo­pyridine mol­ecule by an N—H⋯N hydrogen bond. Two formula units aggregate to form inversion-symmetric dimers involving Br⋯Br, Au⋯Br and H⋯Br contacts.

The compounds 2',3',4',6'-tetra-O-acetyl-β-d-gluco­pyranosyl N'-cyano-N-phenyl­carbamimido­thio­ate (C22H25N3O9S, 5a), 2',3',4',6'-tetra-O-acetyl-β-d-galacto­pyranosyl N'-cyano-N-phenyl­carbamimido­thio­ate, (C22H25N3O9S, 5b), 2',3',4',6'-tetra-O-acetyl-β-d-galacto­pyranosyl N'-cyano-N-methyl­carbamimido­thio­ate (C17H23N3O9S, 5c), and 2',3',4',6'-tetra-O-acetyl-β-d-galacto­pyranosyl N'-cyano-N-p-tolyl­carbamimido­thio­ate (C23H27N3O9S, 5d) all crystallize in P212121 with Z = 4. For all four structures, the configuration across the central (formal) C=N(CN) double bond of the carbamimido­thio­ate group is Z. The torsion angles C5—O1—C1—S (standard sugar numbering) are all close to 180°, confirming the β position of the substituent. Compound 5b involves an intra­molecular hydrogen bond N—H⋯O1; in 5c this contact is the weaker branch of a three-centre inter­action, whereas in 5a and 5d the H⋯O distances are much longer and do not represent significant inter­actions. The C—N bond lengths at the central carbon atom of the carbamimido­thio­ate group are almost equal. All C—O—C=O torsion angles of the acetyl groups correspond to a synperiplanar geometry, but otherwise all four mol­ecules display a high degree of conformational flexibility, with many widely differing torsion angles for equivalent groups. In the crystal packing, 5a, 5c and 5d form layer structures involving the classical hydrogen bond N—H⋯Ncyano and a variety of ‘weak’ hydrogen bonds C—H⋯O or C—H⋯S. The packing of 5b is almost featureless and involves a large number of borderline ‘weak’ hydrogen bonds. In an appendix, a potted history of wavelength preferences for structure determination is presented and it is recommended that, even for small organic crystals in non-centrosymmetric space groups, the use of Mo radiation should be considered.

In the title complex, [U(C10H7N3O3)O2(CH3OH)]n, the UVI cation has a typical penta­gonal–bipyramidal environment with the equatorial plane defined by one N and two O atoms of one doubly deprotonated 2-[5-(2-hy­droxy­phen­yl)-1H-1,2,4-triazol-3-yl]acetic acid ligand, a carboxyl­ate O atom of the symmetry-related ligand and the O atom of the methanol mol­ecule [U—N/Oeq 2.256 (4)–2.504 (5) Å]. The axial positions are occupied by two oxide O atoms. The equatorial atoms are almost coplanar, with the largest deviation from the mean plane being 0.121 Å for one of the O atoms. The benzene and triazole rings of the tetra­dentate chelating–bridging ligand are twisted by approximately 21.6 (2)° with respect to each other. The carboxyl­ate group of the ligand bridges two uranyl cations, forming a neutral zigzag chain reinforced by a strong O—H⋯O hydrogen bond. In the crystal, adjacent chains are linked into two-dimensional sheets parallel to the ac plane by C/N—H⋯N/O hydrogen bonding and π–π inter­actions. Further weak C—H⋯O contacts consolidate the three-dimensional supra­molecular architecture. In the solid state, the compound shows a broad medium intensity LMCT transition centred around 463 nm, which is responsible for its red colour.

A new uranium metal–organic complex salt, [U(C10H9O2)2O2(C2H6O)], with benzoyl acetone, namely, bis­(benzoyl­acetonato)(ethanol)dioxidouranium(VI), was synthesized. The compound has monoclinic P21/n symmetry. The geometry of the seven-coordinate U atom is penta­gonal bipyramidal, with the uranyl oxygen atoms in apical positions. In the complex, the ligands bind to the metal through oxygen atoms. Additional weak O—H⋯O contacts between the cations and anions consolidate the three-dimensional arrangement of the structure. On the Hirshfeld surface, the largest contributions come from the short contacts such as van der Waals forces, including H⋯H, O⋯H and C⋯H. Inter­actions including C⋯C and O⋯C contacts were also observed; however, their contribution to the overall cohesion of the crystal structure is minor. A packing analysis was performed to check the strength of the crystal packing.

BioXTAS RAW is a free open-source program for reduction, analysis and modelling of biological small-angle scattering data. Here, the new developments in RAW version 2 are described. These include improved data reduction using pyFAI; updated automated Guinier fitting and Dmax finding algorithms; automated series (e.g. size-exclusion chromatography coupled small-angle X-ray scattering or SEC-SAXS) buffer- and sample-region finding algorithms; linear and integral baseline correction for series; deconvolution of series data using regularized alternating least squares (REGALS); creation of electron-density reconstructions using electron density via solution scattering (DENSS); a comparison window showing residuals, ratios and statistical comparisons between profiles; and generation of PDF reports with summary plots and tables for all analysis. Furthermore, there is now a RAW API, which can be used without the graphical user interface (GUI), providing full access to all of the functionality found in the GUI. In addition to these new capabilities, RAW has undergone significant technical updates, such as adding Python 3 compatibility, and has entirely new documentation available both online and in the program.

An implementation of Slater-type spherical scattering factors for X-ray and electron diffraction for elements in the range Z = 1–103 is presented within the software Olex2. Both high- and low-angle Fourier behaviour of atomic electron density and electrostatic potential can thus be addressed, in contrast to the limited flexibility of the four Gaussian plus constant descriptions which are currently the most widely used method for calculating atomic scattering factors during refinement. The implementation presented here accommodates the increasing complexity of the electronic structure of heavier elements by using complete atomic wavefunctions without any interpolation between precalculated tables or intermediate fitting functions. Atomic wavefunctions for singly charged ions are implemented and made accessible, and these show drastic changes in electron diffraction scattering factors compared with the neutral atom. A comparison between the two different spherical models of neutral atoms is presented as an example for four different kinds of X-ray and two electron diffraction structures, and comparisons of refinement results using the existing diffraction data are discussed. A systematic but slight improvement in R values and residual densities can be observed when using the new scattering factors, and this is discussed relative to effects on the atomic displacement parameters and atomic positions, which are prominent near the heavier elements in a structure.

A multi-slit very small angle neutron scattering (MS-VSANS) instrument has been finally accepted at the China Spallation Neutron Source (CSNS). It is the first spallation neutron source based VSANS instrument. MS-VSANS has a good signal-to-noise ratio and can cover a wide scattering vector magnitude range from 0.00028 to 1.4 Å−1. In its primary flight path, a combined curved multichannel beam bender and sections of rotary exchange drums are installed to minimize the background downstream of the instrument. An exchangeable multi-slit beam focusing system is integrated into the primary flight path, enabling access to a minimum scattering vector magnitude of 0.00028 Å−1. MS-VSANS has three modes, namely conventional SANS, polarizing SANS and VSANS modes. In the SANS mode, three motorized high-efficiency 3He tube detectors inside the detector tank cover scattering angles from 0.12 to 35° simultaneously. In the polarizing SANS mode, a double-V cavity provides highly polarized neutrons and a high-efficiency 3He polarization analyser allows full polarization analysis. In the VSANS mode, an innovative high-resolution gas electron multiplier detector covers scattering angles from 0.016 to 0.447°. The absolute scattering intensities of a selection of standard samples are obtained using the direct-beam technique; the effectiveness of this method is verified by testing the standard samples and comparing the results with those from a benchmark instrument. The MS-VSANS instrument is designed to be flexible and versatile and all the design goals have been achieved.

With the emergence of ultrafast X-ray sources, interest in following fast processes in small molecules and macromolecules has increased. Most of the current research into ultrafast structural dynamics of macromolecules uses X-ray free-electron lasers. In parallel, small-scale laboratory-based laser-driven ultrafast X-ray sources are emerging. Continuous development of these sources is underway, and as a result many exciting applications are being reported. However, because of their low flux, such sources are not commonly used to study the structural dynamics of macromolecules. This article examines the feasibility of time-resolved powder diffraction of macromolecular microcrystals using a laboratory-scale laser-driven ultrafast X-ray source.

This article demonstrates the feasibility of obtaining accurate pair distribution functions of thin amorphous films down to 80 nm, using modern laboratory-based X-ray sources. The pair distribution functions are obtained using a single diffraction scan without the requirement of additional scans of the substrate or of the air. By using a crystalline substrate combined with an oblique scattering geometry, most of the Bragg scattering of the substrate is avoided, rendering the substrate Compton scattering the primary contribution. By utilizing a discriminating energy filter, available in the latest generation of modern detectors, it is demonstrated that the Compton intensity can further be reduced to negligible levels at higher wavevector values. Scattering from the sample holder and the air is minimized by the systematic selection of pixels in the detector image based on the projected detection footprint of the sample and the use of a 3D-printed sample holder. Finally, X-ray optical effects in the absorption factors and the ratios between the Compton intensity of the substrate and film are taken into account by using a theoretical tool that simulates the electric field inside the film and the substrate, which aids in planning both the sample design and the measurement protocol.

The first Federation of European Biochemical Societies Advanced Course on macromolecular crystallization was launched in the Czech Republic in October 2004. Over the past two decades, the course has developed into a distinguished event, attracting students, early career postdoctoral researchers and lecturers. The course topics include protein purification, characterization and crystallization, covering the latest advances in the field of structural biology. The many hands-on practical exercises enable a close interaction between students and teachers and offer the opportunity for students to crystallize their own proteins. The course has a broad and lasting impact on the scientific community as participants return to their home laboratories and act as nuclei by communicating and implementing their newly acquired knowledge and skills.

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.

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.

X-ray multi-projection imaging (XMPI) is an emerging experimental technique for the acquisition of rotation-free, time-resolved, volumetric information on stochastic processes. The technique is developed for high-brilliance light-source facilities, aiming to address known limitations of state-of-the-art imaging methods in the acquisition of 4D sample information, linked to their need for sample rotation. XMPI relies on a beam-splitting scheme, that illuminates a sample from multiple, angularly spaced viewpoints, and employs fast, indirect, X-ray imaging detectors for the collection of the data. This approach enables studies of previously inaccessible phenomena of industrial and societal relevance such as fractures in solids, propagation of shock waves, laser-based 3D printing, or even fast processes in the biological domain. In this work, we discuss in detail the beam-splitting scheme of XMPI. More specifically, we explore the relevant properties of X-ray splitter optics for their use in XMPI schemes, both at synchrotron insertion devices and XFEL facilities. Furthermore, we describe two distinct XMPI schemes, designed to faciliate large samples and complex sample environments. Finally, we present experimental proof of the feasibility of MHz-rate XMPI at the European XFEL. This detailed overview aims to state the challenges and the potential of XMPI and act as a stepping stone for future development of the technique.

Father's Day is coming quick! But before you run to Walgreen's Sunday morning to find they are sold out of touching cards for the father figure in your life, let us help you curate a fun day out with dad.

Thinking about significant-figure holidays, there seems to be more of a method for planning Mother's Day surprises. You get the breakfast-in-bed together quietly for mom or grandma or aunt, etc., wake her up early on a Sunday, she quickly scrambles to hide the fact that she decided to sleep pantsless, then you present her with some poorly made waffles and juice which she will inevitably spill on her white sheets.

But what about your father-figure? A card? Yes. Maybe a golf ball? Okay. A mug you Amazon Prime'd to him in a last-ditch effort that says "Captain Dad?" Don't do that. It might be weird to ask the men in our life, "What the hell do you want?" under the veil of Father's Day, so to spare you we've compiled some ideas.

Idea #1: Take your father to get pampered! Spa days are are not gender-specific and when was the last time someone even looked at your dad's feet? Hollywood salon Hammer & Nails focuses on men's cuticle care. Treat your dad to a MANi-pedi, and he'll also enjoy a glass of bourbon, a personal flatscreen TV with noise-cancelling headphones, all while relaxing in an over-sized leather chair. Although Hammer & Nails targets men, women are also welcome. 8257 Melrose Ave, Los Angeles, CA 90046.

Idea #2: Take in a tasting. Greenbar Distillery is LA's first spirit distillery since the Prohibition was repealed in 1933. They boast the "World's largest portfolio of organic spirits." Take a tour, pose with their gigantic copper stills and whiskey barrels, sign up for a class, or just taste some of their 16 spirits and five bitters. Their tours are reserved for Saturday so consider this a pregame to your other Father's Day plans. 2459 E 8th St, Los Angeles, California, 90021.

Idea #3: Younger kids? Let's play! Sunday, the Autry Museum of the American West is opening a new exhibit about the history of play. Experience the next generation of toys and games, but also see how they differ across generations and cultures. The exhibit is very interactive and the museum is in beautiful Griffith Park, so there are plenty of hiking trails, picnic spots, or viewpoints to snap some pictures with your man/men.  234 Museum Drive, Los Angeles, CA 90065 .

Idea #4: The Abbey's annual Father's Day Brunch. For the past six years, The Abbey in West Hollywood has hosted a brunch in celebration of LGBT families or those considering starting one. There will be a breakfast buffet from 9am-1pm and attendees can get more info about fostering opportunities. $18 per person. 692 N Robertson Blvd, West Hollywood, CA 90069 .

Much love to all the dads, uncles, grandpas, friends, and men nurturing other people!

Dakota Gold Corp. (DC:NYSE American) announced drill results from the first 17 holes of its ongoing infill drilling program to expand the maiden resource at its Richmond Hill Gold Project in the historic Homestake District of South Dakota.

An updated S-K 1300 resource estimate is planned for Q1 2025 and a S-K 1300 Initial Assessment with cashflow analysis is planned for Q2 2025, the company said in a release. The expanded resource is expected to include an additional 88 new drill holes totaling 17,000 meters.

"The highlight of this morning's release was (hole) RH24C-099, which was drilled in the Twin Tunnels Zone and returned 1.15 g/t Au (grams per tonne gold) over 51.7 meters from 132.9 meters," wrote Canaccord Genuity Capital Markets Analyst Peter Bell in an updated research note on Monday. "The results this morning were consistent with the current resource at Richmond Hill, with many cases reporting higher-than-average grades."

Bell said the firm was encouraged by the results, "which we believe provide support for expansion in future resource estimates. With infill and step out drilling at Richmond Hill being just one of three ongoing drill programs currently underway at Dakota, underscoring the company's emphasis on exploration and expansion."

Drilling Is 'Adding Ounces'

The maiden S-K 1300 resource, announced in April, outlined an Indicated Resource of 51.83 million tonnes (Mt) at 0.80 g/t Au for 1.33 million ounces (Moz) and Inferred Resource of 58.06 Mt at 0.61 g/t Au for 1.13 Moz., the company said.

The initial infill drill results release released Monday encountered further gold mineralization from the central portion of the Richmond Hill resource area consistent with results reported in the maiden resource, Dakota said. The drilling was conducted in areas where the original resource block model contained gaps to support the company's belief that the initial resource could be significantly expanded with additional infill drilling.

Highlights of the results include:

• Hole RH24C-077: 0.76 g/t Au over 24.4 meters
• Hole RH24C-083: 0.70 g/t Au over 13.8 meters
• Hole RH24C-085: 1.10 g/t Au over 17.9 meters
• Hole RH24C-088A: 0.96 g/t Au over 41.5 meters
• Hole RH24C-099: 1.15 g/t Au over 51.7 meters

Dakota said the resource remained open in all directions and could be improved with more drilling, metallurgical work, and incorporation of silver into the resource.

"We are very pleased to see that initial results from our infill drill program are adding ounces to our current S-K 1300 resource," said Dakota Vice President of Exploration James Berry. "The results to date show grades and widths consistent with drill holes in the original block model and support an expansion of gold mineralization, including shallow oxide mineralization. We look forward to continuing our infill program on the other zones identified in our Initial assessment for follow-up drilling."

'Vastly Unexplored' District

The historic Homestake Mine produced 41 Moz Au and 9 Moz silver (Ag) over 126 years. The company has 48,000 acres of holdings surrounding the original mine, which was first discovered in 1876 and consolidated by George Hearst.

Areas surrounding "super-giant deposits" like Homestake are believed to contain significant additional gold resources, wrote John Newell wrote.

Areas surrounding "super-giant deposits" like Homestake are believed to contain significant additional gold resources, wrote John Newell of John Newell & Associates this week for a Streetwise Reports piece on the legacy of the famous mine.

"Super-giant deposits are characterized by clusters of geologically similar deposits within several hundred square kilometers, defining profoundly mineralized regions," Newell wrote. "It is believed that at least twice that amount of gold exists in the neighborhood of these super giants. If that is true, then there are at least 100 Moz of gold left to be found in this vastly underexplored precious metal district of South Dakota."

This proximity to a super-giant "suggests a high potential for similar deposits," Newell wrote. "Being in the shadow of many old mines increases the probability of finding significant mineral resources."

The Catalyst: Gold Continues Bull Market

After hitting a record high of US$2,790.15 per ounce on Thursday, spot gold was up 0.1% to US$2,737.35 on Monday afternoon, according to Reuters.

Investors were keeping a close on Tuesday's presidential election in the U.S. and the Federal Reserve's meeting later this week, Anjana Anil reported.

"A Reuters/Ipsos poll conducted last month found worries that the U.S. could see a repeat of the unrest that followed Trump's 2020 election defeat, when his false claim that his loss was the result of fraud prompted hundreds to storm the U.S. Capitol," Anil wrote.

Gold's rise has "resulted in big returns for the investors who bought in earlier this year," Angelica Leicht reported for CBS News last month. "For example, the investors who purchased gold in March when it hit US$2,160 per ounce have seen their gold values increase by nearly 27% in the time since. That's a huge uptick in value in a matter of months, especially on an asset that's known more for long-term growth."

Recently polled London Bullion Market Association members indicated they believe the gold price could reach US$2,940/oz during 2025, reported Stockhead on Oct. 28.

"Combined with expectations of lower global interest rates, this further enhances gold's attractiveness as an investment," the article noted.[OWNERSHIP_CHART-7442]

As for gold equities, the S&P/TSX Venture Composite Index (SPCDNX) confirmed a multidecade bull run for junior, intermediate, and senior mining stocks when it closed above 1,000 recently, Stewart Thomson with 321Gold wrote. The index is a key indicator of the health of the general gold, silver, and mining stocks market.

Perhaps the only respite pandemic closures brought to my family — which includes two kids under age 6 — was freedom from the constant misery of dripping noses, sneezes and coughs. And statistics suggest we weren't the only ones who had fewer colds last year: With daycares and in-person schools closed and widespread use of masks and hand sanitizer in most communities, cases of many seasonal respiratory infections went down, and flu cases dropped off a cliff.

That reprieve might be ending. Social mixing has been starting up again in much of the U.S. and so have cases of garden-variety sniffles. The Centers for Disease Control and Prevention just warned physicians that RSV, a unpleasant respiratory virus, is surging right now in southern states. And it's not just happening in the U.S. — researchers in the U.K. and Hong Kong found that rhinovirus outbreaks spiked there, too, when COVID-19 lockdowns ended.

My family is at the vanguard of this trend. Right after Washington D.C. lifted its mask mandate a few weeks ago, both my kids got runny noses and coughs, and as soon as they tested negative for COVID-19, my pandemic fears were replaced by a familiar dread. I had visions of sleepless, cough-filled nights, dirty tissues everywhere, and — in short order — my own miserable cold.

"If someone in your house is sick, you're not only breathing in their sick air, you're touching those contaminated surfaces. You're having closer contact, you're having longer exposures," says Seema Lakdawala, a researcher at the University of Pittsburgh School of Medicine, who studies how influenza viruses transmit between people. It can start to feel inevitable that the whole family will get sick.

Take heart, my fellow parents-of-adorable-little-germ-machines! Lakdawala says many strategies we all picked up to fight COVID-19 can also stop the spread of many routine respiratory viruses. In fact, they may be even more effective against run-of-the-mill germs, since, unlike the viruses behind most colds, SARS-CoV2 was new to the human immune system.

Those strategies start with everyone keeping their children home from school, camp and playdates when they're sick and keeping up with any and all vaccinations against childhood illnesses. Beyond that, specialists in infectious disease transmission I consulted offer five more tips for keeping my family and yours healthier this summer.

Tip #1: Hang on to those masks

In pre-pandemic times, it might have seemed like a weird move to put on a mask during storytime with your drippy-nosed kid, but Dr. Tina Tan says that's her top tip. She's a professor of pediatrics at the Feinberg School of Medicine at Northwestern University and a pediatric infectious disease physician at Lurie Children's Hospital in Chicago.

When it comes to influenza, a rhinovirus, or any of the other respiratory bugs constantly circulating, "once these viruses touch your mucous membranes, whether it's your eyes, your nose or your mouth, you do have a chance of contracting it," says Tan. Masks help stop infectious particles and virus-filled droplets from getting into your body.

"You don't need a N95," Tan says. A light-weight surgical mask or homemade cloth mask can work as long as it has two or more layers. The mask-wearing also doesn't have to be constant. "If you're going to be face to face with them — they're sitting in your lap, you're reading to them, you're feeding them, etc. — then I would say wear a mask," Tan advises.

Even better, if it's not too uncomfortable for your sick child, have them wear a mask, Lakdawala says. "If your kids are old enough to wear a mask, that would probably be the best strategy, because then you're reducing the amount of virus-laden aerosols in the environment."

How long should you stay masked-up?

For most respiratory viruses, "the infectious period is probably similar to that of COVID," says Dr. Jennifer Shu, a pediatrician in Atlanta and medical editor of the American Academy of Pediatrics' site HealthyChildren.org. It might technically start a few days before symptoms begin and last for up to two weeks, but your sniffly kids are likely most contagious during those first runny-nosed days Shu says. "You could have kids over [age] 2 wear a mask for the first three or four days of symptoms," she suggests.

And if you can't bring yourself to wear a mask or put one on your child inside your own home to fight a cold, don't worry. Lakdawala has a few more ideas.

Tip #2: Air it out, space it out

When Lakdawala's 5- and 8-year-old kids get sick, "I open the windows, I turn on the fans, I get a lot more air circulation going on in the house," she says — that is, weather and allergies permitting, of course.

"A lot of these viruses tend to circulate more during the colder weather, so where you live is going to determine how much you can open your windows," Tan points out. But certainly, she says, "the better the ventilation, the less likely the viruses are going to get transmitted from one person to another."

What about buying HEPA filter air purifiers, or changing the filter in your heating and air conditioning system? "I would not suggest going out to purchase extra HEPA filters just for this purpose," says Dr. Ibukun Kalu, a pediatric infectious disease physician at Duke University. For hospitals that are treating very contagious and serious pathogens like tuberculosis or SARS-CoV2, those upgrades may be important, she says. "But for all of the other routine viruses, it's routine ventilation."

Kalu says you might also want to think strategically about creating some social distance — when it's possible — like strategically having the parent who tends not to get as sick provide the one-on-one care for the sick kid.

Obviously, you can't isolate a sick child in a room by themselves until they recover, but Lakdawala says not getting too close or for too long can help. When her kids are sick, "I do try to just not snuggle them — keep them a little bit at a distance."

Tip #3: Don't try to be a HAZMAT team

There's good news on the house-cleaning front. "Most of these viruses don't live on surfaces for very long periods of time," says Tan.

The research on exactly how long cold-causing rhinoviruses can survive on surfaces — and how likely they are to remain infectious — isn't definitive. As Dr. Donald Goldmann of Boston Children's Hospital poetically put it in The Pediatric Infectious Disease Journal a couple decades ago, "Despite many years of study, from the plains of Salisbury, to the hills of Virginia, to the collegiate environment of Madison, WI, the precise routes rhinovirus takes to inflict the misery of the common cold on a susceptible population remain controversial." That's still true today, doctors say.

There's some evidence that contaminated surfaces are not very important in the spread of colds. In one little study from the 1980s, a dozen healthy men played poker with cards and chips that "were literally gummy" from the secretions of eight other men who had been infected with a rhinovirus as part of the study. Even after 12 hours of poker, none of the healthy volunteers caught colds.

Shu's take home advice? Be methodical in your cleaning of often-touched surfaces (kitchen table, countertops and the like) with soap and water when everybody's healthy, and maybe add bleach wipes or other disinfectant when someone in your household has a cold. But don't panic.

Tan agrees. "Wipe down frequently-touched surfaces multiple times a day," she says. "But you don't have to go crazy and, like, scour everything down with bleach."

You also don't need to do a lot of extra laundry in hopes of eliminating germs on clothes, towels, dishtowels and the like — that can be exhausting and futile. Instead, just try to encourage kids who are sick to use their own towel — and do what you can to give towels a chance to dry out between uses. "Having some common sense and doing laundry every few days — washing your towels every few days and washing your sheets every couple of weeks — is probably good enough," Shu says. "You don't need to go overboard for run-of-the-mill viruses."

Don't fret that there are germs everywhere and you can't touch anything, says Lakdawala. "If I touch something, that -- in itself — is not infecting me," she notes. Instead, it's getting a certain amount of virus on our hands and then touching our own nose, eyes or mouth that can infect us. "If I just go wash my hands, that risk is gone," Lakdawala says.

You can also skip wearing gloves around the house. "People think that they are safe when they're wearing the gloves — and then they touch their face with their gloves [on]" and infect themselves, she says.

Instead, just make it a habit to wash your hands frequently.

Tip #4: Seriously, just wash your hands

"The same handwashing guidelines for COVID also apply for common respiratory illnesses," Shu says. That is: regular soap with warm water, lathered for about 20 seconds.

"The reason why 20 seconds is recommended is because some studies show that washing your hands shorter than that doesn't really get rid of germs." She warns that there hasn't been a whole lot of research on this, and 20 seconds is not a magic number. "But it is thought that anywhere from 15 to 30 seconds is probably good enough to get rid of most of the germs," she says. (Note: No need to drive your family crazy singing the birthday song twice — y'all have options.)

"Wash your hands before you eat, after you eat, after you go to the bathroom ... if you're changing your child's diaper, et cetera.," says Tan. "And if you're going to use hand sanitizer, it has to be at least 60% alcohol."

"Your hands are probably the most important source of transmission outside of someone really coughing or sneezing in your face," Kalu adds.

Tip #5: Don't give up, but do keep perspective

So, what if your beloved child does cough or sneeze in your face? Should you then forget all this stuff and just give in to the inevitable?

Don't give up, says Lakdawala. "Just because you got one large exposure in your mouth and in close range, it doesn't mean that that was sufficient to initiate an infection," she says. Whether you get sick from that germy onslaught is going to depend on a lot of things — the particular virus, whether the sneeze landed in your mouth or nose, whether you've been exposed to some version of that virus before and more.

One tiny positive side effect of the coronavirus pandemic for Lakdawala has been a broader public understanding of "dose-response" in viral transmission. "Just because somebody breathed on you once doesn't necessarily mean that that's what's going to get you infected," she says.

Consider practicing the swiss cheese model of transmission control, Shu says. "Every layer of protection helps — if you find that wearing a face shield is too much, but you do everything else, you're still going to limit your exposure," she says. Just do what works for you and your family.

It's something that many of us reckon with: the sense that we're not quite as sharp as we once were.

I recently turned 42. Having lost my grandfather to Alzheimer's, and with my mom suffering from a similar neurodegenerative disease, I'm very aware of what pathologies might lurk beneath my cranium.

In the absence of a cure for Alzheimer's and other forms of dementia, the most important interventions for upholding brain function are preventive — those that help maintain our most marvelous, mysterious organ.

Based on the science, I take fish oil and broil salmon. I exercise. I try to challenge my cortex to the unfamiliar.

As I wrote my recent book, A History of the Human Brain, which recounts the evolutionary tale of how our brain got here, I began to realize that so many of the same influences that shaped our brain evolution in the first place reflect the very measures we use to preserve our cognitive function today.

Being social, and highly communicative. Exploring creative pursuits. Eating a varied, omnivorous diet low in processed foods. Being physically active.

These traits and behaviors help retrace our past, and, I believe, were instrumental in why we remain on the planet today.

And they all were, at least in part, enabled by our brain.

Social smart alecks finish first

The human saga is riddled with extinctions.

By "human," I don't just mean Homo sapiens, the species we belong to, but any member of the genus Homo. We've gotten used to being the only human species on Earth, but in our not so distant past — probably a few hundred thousand years ago – there were at least nine of us running around.

There was Homo habilis, or the "handy man." And Homo erectus, the first "pitcher." The Denisovans roamed Asia, while the more well-known Neanderthals spread throughout Europe.

But with the exception of Homo sapiens, they're all gone. And there's a good chance it was our fault.

Humans were never the fastest lot on the African plains, and far from the strongest. Cheetahs, leopards and lions held those distinctions. In our lineage, natural selection instead favored wits and wiliness.

Plenty of us became cat food, but those with a slight cognitive edge — especially Homo sapiens — lived on. In our ilk, smarts overcame strength and speed in enabling survival.

Ecology, climate, location and just sheer luck would've played important roles in who persisted or perished as well, as they do for most living beings. But the evolutionary pressure for more complex mental abilities would lead to a massive expansion in our brain's size and neurocircuitry that is surely the paramount reason we dominate the planet like no other species ever has.

Much of this "success," if you can call it that, was due to our social lives.

Primates are communal creatures. Our close monkey and ape cousins are incredibly interactive, grooming each other for hours a day to maintain bonds and relationships. Throw in a few hoots and hollers and you have a pretty complex community of communicating simians.

An active social life is now a known preserver of brain function.

Research shows that social isolation worsens cognitive decline (not to mention mental health, as many of us experienced this past year). Larger social networks and regular social activities are associated with mental preservation and slowed dementia progression.

Entwined in this new social life was an evolutionary pressure that favored innovation. Our eventual ability to generate completely novel thoughts and ideas, and to share those ideas, came to define our genus.

As we hunted and foraged together, and honed stones into hand axes, there was a collective creativity at work that gave us better weapons and tools that enabled more effective food sourcing, and, later, butchering and fire. Effectively sharing these innovations with our peers allowed information to spread faster than ever before - a seed for the larger communities and civilizations to come.

Challenging ourselves to new pursuits and mastering new skills can not only impress peers and ingratiate us to our group, but literally help preserve our brain. New hobbies. New conversations. Learning the banjo. Even playing certain video games and simply driving a new route home from work each day, as neuroscientist David Eagleman does, can keep our function high.

Whether it's honing ancient stone or taking up Sudoku, any pursuit novel and mentally challenging may help keep the neural circuits firing.

We really are what we eat

All the while, as we hunted and crafted in new and communal ways, we had to eat. And we did so with an uniquely adventurous palette.

Homo sapiens is among the most omnivorous species on the planet. Within reason we eat just about anything. Whether it's leaves, meat, fungus, or fruit, we don't discriminate. At some point, one of us even thought it might be a good idea to try the glistening, grey blobs that are oysters - and shellfish are, it turns out, among the healthiest foods for our brain.

The varied human diet is an integral part of our story. As was the near constant physicality required to source it.

On multiple occasions over the past 1 to 2 million years climate changes dried out the African landscape, forcing our ancestors out of the lush forest onto the dangerous, wide-open grasslands. As evolution pressured us to create and commune to help us survive, a diverse diet also supported our eventual global takeover.

Our arboreal past left us forever craving the dangling fruits of the forest, a supreme source of high-calorie sugars that ensured survival. Back then we didn't live long enough to suffer from Type 2 diabetes: if you encountered sweets, you ate them. And today we're stuck with a taste for cookies and candy that, given our longer lifespans, can take its toll on the body and brain.

But humans were just as amenable to dining on the bulbs, rhizomes and tubers of the savanna, especially once fire came along. We eventually became adept scavengers of meat and marrow, the spoils left behind by the big cats, who preferred more nutritive organ meat.

As our whittling improved we developed spears, and learned to trap and hunt the beasts of the plains ourselves. There is also evidence that we learned to access shellfish beds along the African coast and incorporate brain-healthy seafood into our diet.

Studying the health effects of the modern diet is tricky. Dietary studies are notoriously dubious, and often involve countless lifestyle variables that are hard to untangle.

Take blueberries. Multiple studies have linked their consumption with improved brain health. But, presumably, the berry-prone among us are also more likely to eat healthy all around, exercise, and make it to level 5 on their meditation app.

Which is why so many researchers, nutritionists, and nutritional psychiatrists now focus on dietary patterns, like those akin to Mediterranean culinary customs, rather than specific ingredients. Adhering to a Mediterranean diet is linked with preserved cognition; and multiple randomized-controlled trials suggest doing so can lower depression risk.

A similar diversity in our ancestral diet helped early humans endure an ever-shifting climate and times of scarcity. We evolved to subsist and thrive on a wide range of foods, in part because our clever brains allowed us access to them. In turn, a similarly-varied diet (minus submitting to our innate sugar craving of course) is among the best strategies to maintain brain health.

All of our hunting, and foraging, and running away from predators would have required intense physical exertion. This was certainly not unique to humans, but we can't ignore the fact that regular exercise is another effective means of preserving brain health.

Being active improves performance on mental tasks, and may help us better form memories. Long before the Peletons sold out, our brains relied on both mental and physical activity.

But overwhelmingly the evidence points to embracing a collection of lifestyle factors to keep our brain healthy, none of which existed in a Darwinian vacuum.

Finding food was as social an endeavor as it was mental and physical. Our creative brains harnessed information; gossiping, innovating, and cooking our spoils around the campfire.

Researchers are beginning to piece together the complex pathology behind the inevitable decline of the human brain, and despite a parade of failed clinical trials in dementia, there should be promising treatments ahead.

Until then, in thinking about preserving the conscious experience of our world and relationships — and living our longest, happiest lives — look to our past.

The U.S. Supreme Court ends its spring term today with two final decisions expected to come down, one involving a pivotal voting rights case out of Arizona and the other involving so-called “dark money” and campaign finance. 

Today on AirTalk, we’ll get a summary of the arguments that each side in the two cases will be making, and we’ll look back on the Spring 2021 term overall, as the nine justices will break until the fall.

We know that President Biden won the 2020 election (regardless of what former President Donald Trump and his allies say). We just haven't had a great picture of how Biden won.

That is until Wednesday, when we got the clearest data yet on how different groups voted, and crucially, how those votes shifted from 2016. The Pew Research Center just released its validated voters' report, considered a more accurate measure of the electorate than exit polls, which have the potential for significant inaccuracies.

The new Pew data shows that shifts among suburban voters, white men and independents helped Biden win in November, even while white women and Hispanics swung toward Trump from 2016 to 2020.

To compile the data, Pew matches up survey respondents with state voter records. Those voter files do not say how a person voted, but they do allow researchers to be sure that a person voted, period. That helps with accuracy, eliminating the possibility of survey respondents overreporting their voting activity. In addition, the Pew study uses large samples of Americans — more than 11,000 people in 2020.

It's a numbers-packed report, but there are some big takeaways about what happened in 2020 (and what it might tell us about 2022 and beyond):

Suburban voters (especially white suburban voters) swung toward Biden

Suburban voters appear to have been a major factor helping Biden win. While Pew found Trump winning the suburbs by 2 points in 2016, Biden won them by 11 points in 2020, a 13-point overall swing. Considering that the suburbs accounted for just over half of all voters, it was a big demographic win for Biden.

That said, Trump gained in both rural and urban areas. He won 65% of rural voters, a 6-point jump from 2016. And while cities were still majority-Democratic, his support there jumped by 9 points, to 33%.

Men (especially white men) swung toward Biden

In 2020, men were nearly evenly split, with 48% choosing Biden to Trump's 50%. That gap shrank considerably from 2016, when Trump won men by 11 points. In addition, this group that swung away from Trump grew as a share of the electorate from 2016 — signaling that in a year with high turnout, men's turnout grew more.

White men were a big part of the swing toward Biden. In 2016, Trump won white men by 30 points. In 2020, he won them again, but by a substantially slimmer 17 points.

In addition, Biden made significant gains among married men and college-educated men. All of these groups overlap, but they help paint a more detailed portrait of the type of men who might have shifted or newly participated in 2020.

However, we can't know from this data what exactly was behind these shifts among men — for example, exactly what share of men might have sat on the sidelines in 2016, as opposed to 2020.

Women (especially white women) swung toward Trump

The idea that a majority of white women voted for Trump quickly became one of the 2016 election's most-cited statistics, as many Hillary Clinton supporters — particularly women — were outraged to see other women support Trump.

While that statistic was repeated over and over, Pew's data ultimately said this wasn't true — they found that in 2016, white women were split 47% to 45%, slightly in Trump's favor but not a majority.

This year, however, it appears that Trump did win a majority of white women. Pew found that 53% of white women chose Trump this year, up by 6 points from 2016.

This support contributed to an overall shift in women's numbers — while Clinton won women of all races by 15 points in 2016, Biden won them by 11 points in 2020. Combined with men's shifts described above, it shrank 2016's historic gender gap.

Notably, the swing in white women's margin (5 points altogether) was significantly smaller than white men's swing toward Biden (13 points altogether).

Hispanic voters swung toward Trump

Trump won 38% of Hispanic voters in 2020, according to Pew, up from 28% in 2016.

That 38% would put Trump near George W. Bush's 40% from 2004 — a recent high-water mark for Republicans with Hispanic voters. That share fell off substantially after 2004, leading some Republican pollsters and strategists to wonder how the party could regain that ground. Trump in 2016 intensified those fears, with his nativist rhetoric and hard-line immigration policies.

There are some important nuances to these Hispanic numbers. Perhaps most notably, there is a sizable education gap. Biden won college-educated Hispanic voters by 39 points, but the Democrat won those with some college education or less by 14 points.

That gap mirrors the education gap regularly seen in the broader voting population.

Unfortunately, Pew's sample sizes from 2016 weren't big enough to break down Hispanic voters by gender that year, so it's impossible to see if this group's gender gap widened.

Nonwhite voters leaned heavily toward Biden

Unlike white and Hispanic voters, Black voters didn't shift significantly from 2016. They remained Democratic stalwarts, with 92% choosing Biden — barely changed from four years earlier.

Nearly three-quarters of Asian voters also voted for Biden, along with 6 in 10 Hispanic voters and 56% of voters who chose "other" as their race. (Those groups' sample sizes also weren't big enough in 2016 to draw a comparison over time.)

2018 trends stuck around ... but diminished

In many of these cases where there were substantial shifts in how different groups voted, they weren't surprising, given how voters in the last midterms voted. For example, white men voted more for Democrats in 2018 than they did in 2016, as did suburban voters.

What it means for 2022

The data signals that Democrats' strength with Hispanic voters has eroded, but that the party succeeded in making further inroads in the suburbs, including among suburban whites.

It suggests that these groups, already major focuses for both parties, will continue to be so in 2022, with Republicans trying to cement their gains among Hispanics (and regain suburban voters), while Democrats do Hispanic outreach and try to hold onto the suburbs.

However, it's hard to project much into the future about what voters will do based on the past two elections because of their unique turnout numbers.

"It's hard to interpret here, because 2018 was such a high turnout midterm election, and then our last data point, 2014, was a historically low turnout midterm election," said Ruth Igielnik, senior researcher at Pew Research Center.

Normal is not easily defined.

The past 15 months, though, have certainly been anything but.

Americans are starting to believe a "sense of normal" is approaching fairly soon, however, according to a new NPR/PBS NewsHour/Marist survey. The poll also found that with the coronavirus receding in this country, mask-wearing is declining and Americans are going out more. But they remain cautious about being in large crowds.

As the country continues to open up, more focus turns to the economy, which cratered during the beginning of the pandemic last year. And Americans are split by race, gender and politics on whether President Biden's ambitious policies are helping or not.

Race, gender, party divides on Biden and the economy

Three months ago, in a similar survey, 49% of adults said the president's policies were strengthening the economy, while 44% said they were weakening it.

Now, that's declined a net of 6 points, as 44% of respondents in the new poll say Biden's policies have strengthened the economy and 45% say the opposite. The percentage who were unsure also jumped 4 points. It's all a little bit of a warning sign for Biden, as he pushes for two large — and expensive — spending packages.

There are significant splits by race and gender:

• Just 39% of whites said Biden's policies have strengthened the economy, but 52% of people of color say they have.
• 54% of independent men say his policies have weakened the economy, while 56% of independent women say they've strengthened it. 
• 45% of white male college grads say Biden has strengthened the economy, but a significantly higher 64% of white women with college degrees said so.

Inflation vs. wages by party

A quarter of Americans rank inflation as the U.S. economy's top concern. That's followed by wages, unemployment, housing costs, labor shortages, gas prices and interest rates.

But there's a sharp political divide on the question. Republicans and independents rank inflation as their top concern, while for Democrats, it was wages. Just 4% of Republicans said wages were their top concern.

Return to "normal"

Americans are growing increasingly optimistic about when life will return to a "sense of normal," as the survey labels it.

In April, three-quarters of Americans said they believe it will take six months or more. Now, it's just half. About a quarter (27%) say it will be less than six months, up from 15% two months ago.

People are also growing more comfortable doing certain things, saying they're:

• dining out at restaurants (78%) and 
• visiting unvaccinated friends and family (75%).

But they are not as comfortable doing others:

• almost 7-in-10 are not going out to bars; 
• about two-thirds are not attending live concerts or sporting events (65%);
• and a majority have also not resumed going to in-person religious services (54%).

COVID-19 vaccines and going back to work

While half say they are concerned about another coronavirus surge, almost 9-in-10 U.S. adults with jobs say they are at least somewhat comfortable returning to work.

Notably, a majority (57%) of those with jobs do not believe employers should require COVID-19 vaccines as a condition to return to in-person work.

More than a quarter of Americans say they will not get vaccinated. The most resistant to getting vaccinated continue to be supporters of former President Donald Trump. Half of them say they won't get the shot, the highest of any group surveyed. Trump has touted the vaccine and got it himself.

Since Centers for Disease Control and Prevention guidelines came out, noting that Americans who have been vaccinated can largely set masks aside, there's been a double-digit decline in those saying they wear a mask even when it's not required.

There's also been a double-digit increase in those saying they generally do not wear a mask. In May, 49% said they wore masks even when it was not required. Now, that's just 36%.

One-in-five said they generally do not wear masks. Two months ago, it was less than one-in-10.

Affordability, not coronavirus, limiting vacations

Speaking of getting back to normal, a majority of Americans say they plan to take a vacation this summer.

But of the significant minority (45%) who say they aren't taking one, almost three times as many cited affordability (35%) as the main reason for not going, as opposed to concerns about COVID-19 (12%).

Methodology: The poll of 1,115 U.S. adults was conducted using live telephone interviewers from June 22 through June 29. Survey questions were available in English or Spanish. The full sample has a margin of error of plus or minus 3.7 percentage points, with larger margins of error for smaller group subsets.

Needle pricks not your thing? A team of National Science Foundation-funded scientists is developing wearable skin sensors that can detect what's in your sweat. They hope that one day, monitoring perspiration could bypass the need for more invasive procedures like blood draws, and provide real-time updates on health problems such as dehydration or fatigue. In a new paper, the team describes a new sensor design that can be rapidly manufactured using a "roll-to-roll" processing technique that essentially prints the sensors onto a sheet of plastic like words on a newspaper. They used the sensors to monitor the sweat rate, and the electrolytes and metabolites in sweat, from volunteers who were exercising, and others who were experiencing chemically induced perspiration. The new sensors contain a spiraling microscopic tube, or microfluidic, that wicks sweat from the skin. By tracking how fast the sweat moves through the microfluidic, the sensors can report how much a person is sweating, or their sweat rate. The microfluidics are also outfitted with chemical sensors that can detect concentrations of electrolytes like potassium and sodium, and metabolites like glucose.

Live-event spaces, like the Sound Nightclub in Los Angeles, have been waiting months for emergency relief.; Credit: Mario Tama/Getty Images

Owners of live-music venues, theaters, museums and other businesses covered under the Shuttered Venue Operators Grant, or SVOG, can expect to see money by the end of May. This is according to an update from the Small Business Administration, which has been handling the SVOG program's bumpy rollout.

An SBA spokesperson said in an email that since the portal to apply for these grants opened a week ago, 10,300 applications have been submitted (another 12,000 have been started but not completed). The vast majority of those applications were from "Live venue operators or promoters," followed by performing arts organizations and then movie theaters.

The SBA has been reviewing applications and said in a statement that "applicants will receive notice of awards this month," with disbursement by the end of May if the applicant responds in a "timely manner to the notice of award."

The SVOG program is a $16 billion emergency relief program that then-President Donald Trump signed into law in late December 2020. It was a bipartisan effort to get aid money to struggling music venues and other arts and live-event spaces that have been hit hard by the coronavirus struggles. But for an emergency relief program, it has taken months to get money in the hands of business owners holding off landlords, insurance companies and other creditors. Those owners spent early 2021 waiting on an official announcement of when they could apply for the grant money while compiling any documents and paperwork they thought they might need. Then once the application site was up and running, it crashed and was closed.

Even as large festivals roll out throughout the U.S. and bands announce tours for later in the year, many small live-event spaces are still at risk of closing. The National Independent Venue Association, one of the most vocal groups lobbying for support for live-music venues, has long stated that 90% of its members would be forced to close without any aid — which would hurt nearby bars, restaurants and shops, not to mention the large apparatus that is the live touring-arts industry.

#FreeBritney activists protest outside the Los Angeles Superior Court during one of Britney Spears' hearings this April.; Credit: Matt Winkelmeyer/Getty Images

Pop star Britney Spears hasn't been in charge of her personal life or her finances for 13 years — that's how long she has been in a court-dictated legal arrangement called a conservatorship.

But on Wednesday, the artist will be speaking directly, albeit from a remote location, to a Los Angeles Superior Court judge about her situation. What exactly she intends to say in her appearance and what her goals might be are anyone's guess.

Before then, here's a quick look at what conservatorships are and why they exist, the specifics of Spears' arrangements, the #FreeBritney movement and what Spears and others have said publicly — and privately — about her conservatorship.

What is a conservatorship, and why does one get put in place?

Typically, legal and financial conservatorships are arranged for people who are unable to make their own decisions in their own best self-interest, such as in the case of an elderly person or someone with some kind of cognitive impairment.

Why does Britney Spears have one?

The exact reasons that the 39-year-old Spears is under a conservatorship have not been publicly disclosed. She lost her autonomy 13 years ago, in 2008, after apparently suffering a mental health crisis.

During the time that Spears has lived under this arrangement, though, she has released four albums (two of which, 2008's Circus and 2011's Femme Fatale, achieved platinum sales); appeared as a judge on both The X Factor and American Idol; and had a four-year residency in Las Vegas that reportedly grossed close to $138 million. Those accomplishments don't exactly line up with the typical profile of someone unable to look after themselves.

What does Spears' conservatorship cover?

Essentially, it controls all the major aspects of Spears' life, including decisions regarding her financial, medical and personal well-being. The conservators also oversee visitation arrangements with her two teenage sons, who are under the full custody of her ex-husband, Kevin Federline.

According to Forbes, Spears' current net worth is around $60 million.

Who controls Spears' conservatorship?

Up until recently, both the financial and personal arms of the conservatorship were controlled by Spears' father, Jamie Spears.

In 2020, her lawyer, Samuel D. Ingham III, stated in a filing that Spears "strongly opposed" her father as conservator and that she refused to perform if he remained in charge of her career. Spears asked the court for her father to be suspended from his role as conservator. (He had temporarily stepped away in 2019 for health reasons.)

In February, Los Angeles Superior Court Judge Brenda Penny overruled an objection from Jamie Spears to having a third party help look after his daughter's financial affairs. A wealth-management company, Bessemer Trust, is now a co-conservator for the financial side of Spears' situation. But Jamie Spears is still the main conservator for all other aspects of Spears' arrangement.

Why is Spears planning to talk to the court now?

Back in April, Spears' legal team asked Penny to allow her to speak to the court directly about the conservatorship, and they agreed that June 23 would be the date for this to happen. At the time, Ingham did not disclose why Spears wants to speak or what she intends to say.

Has Spears ever asked for the conservatorship to end?

Up until now, Spears has never voiced a desire for the conservatorship to be removed completely — at least not publicly. In a court filing, she has stated that the conservatorship "rescued her from a collapse, exploitation by predatory individuals and financial ruin" and allowed her to "regain her position as a world class entertainer."

But on Tuesday afternoon, The New York Times reported that it had obtained confidential court records that purport to show that Spears has opposed the conservatorship privately for years. The Times quoted a 2016 report from a court investigator assigned to Spears' case, in which the investigator wrote that Spears told her that the conservatorship had "become an oppressive and controlling tool against her" and that she wanted the arrangement to end quickly.

According to the Times, Spears told the court in 2019 that the conservatorship had forced her into a stay at a mental health facility, as well as into making public performances against her will. The article further reported that the conservatorship had dictated Spears' friendships, her dating life and her spending habits, even preventing her from refinishing kitchen cabinets according to her taste.

As early as 2014, the article states, Spears wanted to consider removing her father from his prime role in the conservatorship, citing his reportedly heavy drinking.

Does Spears herself support the #FreeBritney movement?

Certain Spears fans have organized themselves into a grassroots movement — #FreeBritney — to help Spears regain autonomy over her life. The dynamics between Spears and her dedicated #FreeBritney fans are murky, as are her various declarations on social media.

In a court filing last September, her lawyer, Ingham, wrote: "At this point in her life when she is trying to regain some measure of personal autonomy, Britney welcomes and appreciates the informed support of her many fans."

On the other hand, Spears to date has never publicly asked to be released from the conservatorship and regain her autonomy — which is the main goal of #FreeBritney.

A very sympathetic New York Times television documentary, Framing Britney Spears, debuted on FX in February. The project reckons with the way the media, comedians and the music industry itself characterized Spears during her ascent to global fame and during her later, very public struggles — and it also profiles some #FreeBritney activists.

After it aired, Spears wrote on Instagram: "My life has always been very speculated [sic] ... watched ... and judged really my whole life !!! ... I didn't watch the documentary but from what I did see of it I was embarrassed by the light they put me in ... I cried for two weeks and well .... I still cry sometimes !!!!"

Some #FreeBritney supporters don't believe Spears writes her own Instagram messages, leaving them to speculate about the pop star's true feelings. But Spears reportedly told TMZ in April that she writes her own captions.

What's next for Britney Spears?

Unclear. In an Instagram video posted last week, a visibly jittery Spears professed to be answering fans' most burning questions, including her shoe size and her favorite business trip (answer: "a trip to Italy [to] Donatella Versace. ... She fined [sic] and dined us").

The last question Spears put forward to herself was a crucial one: Would she ever return to the stage again?

"I have no idea," she said. "I'm having fun right now. I'm in transition in my life, and I'm enjoying myself."

Part 4 of TED Radio Hour episode An SOS From The Ocean

Legendary oceanographer Sylvia Earle has been exploring and working to protect our oceans for more than half a century. Her message has stayed the same: we're taking our oceans for granted.

About Sylvia Earle

Sylvia Earle is an oceanographer, explorer, and author. She is the president of Mission Blue, an organization that aims to establish marine protected areas around the world. She is also a National Geographic Explorer.

Earle has led more than 50 expeditions and clocked more than 7,000 hours underwater. She was captain of the first all-female team to live underwater in 1970--one of many extended underwater stays. In 1979, she walked untethered on the sea floor at a lower depth than any other woman before or since. In the 1980s, she started the companies Deep Ocean Engineering and Deep Ocean Technologies with engineer Graham Hawkes to design undersea vehicles that allow scientists to work at previously inaccessible depths. In the early 1990s, she served as Chief Scientist of the National Oceanographic and Atmospheric Administration. In 2009, she became the recipient of the million dollar TED Prize to continue her work to protect oceans.

Earle received an associate degree from St. Petersburg Jr. College, has a Bachelor of Science and Master of Science degree from Florida State University, and a Doctorate of Psychology from Duke University.

Traffic on Interstate 95 was diverted for hours after a group of armed men fled from police near Wakefield, Mass. on Saturday. Massachusetts state police say 11 suspects have been taken into custody.; Credit: Michael Dwyer/AP

Eleven people were taken into custody Saturday after an hours-long standoff with police early Saturday outside Boston.

While police engaged in negotiation, members of the group engaged the public on social media, saying their group was called "Rise of the Moors."

The heavily armed men were said to be driving from Rhode Island to Maine for "training."

The incident started around 1:30 a.m., when state police noticed two cars stopped at the side of I-95 near Wakefield, Mass., apparently out of fuel. As troopers stopped to assist, they noticed that some individuals near the cars had "military-style" gear, and were carrying long guns and pistols, Massachusetts State Police Col. Christopher Mason told reporters.

"You can imagine 11 armed individuals standing with long guns slung on an interstate highway at 2 in the morning certainly raises concerns and is not consistent with the firearms laws that we have in Massachusetts," Mason said.

Police requested backup, and thus began a standoff that lasted several hours. The men refused to lower their weapons, saying that they "don't recognize our laws," police said. Some of the armed men fled into a nearby wooded area, police said, and a portion of I-95 was closed for several hours.

The standoff was broadcast on social media

Around 4 a.m., a man whom the Boston Globe identified as Jamhal Talib Abdullah Bey said he was broadcasting live from I-95 and said that he told police they had nothing to fear.

"I reassured them that we are not sovereign citizens," a man who appeared to be Bey said in a live-streamed video. "I reassured them that we are not Black identity extremists. I reassured them that we are not anti-police. I reassured them that we are not anti-government. I reassured them that these men here will not be pointing guns at them. I reassured them that we are trying to come to a peaceful resolution."

"We're going to our private land to train, which is our Second Amendment right," he said, showing a vehicle he said contained camping equipment.

As police tactical teams brought in armored vehicles to surround the area, and negotiators interacted with the men, they ultimately surrendered. Middlesex County District Attorney Marian Ryan told reporters the suspects were expected to appear in court on Tuesday morning.

State police "don't have any knowledge about this particular specific group" but as state police "it is not unusual for us to encounter people that have sovereign citizen ideologies — I'm not saying that this group does — but we have had those encounters before in the past," Mason said at a Saturday morning press briefing.

"We train to those encounters," Mason continued. "We very much understand the philosophy that underlies that mindset. And we train our officers, actually, at the academy, on these interactions and how to de-escalate those situations, and how to engage with people that have that philosophy and mindset and resolve those situations in a peaceful manner."

The group calls itself "Rise of the Moors"

The same man appearing to be Bey said in a later video: "They keep portraying us as being anti-government, but we're not anti-government at all."

The group's website lists Bey as a leader of the "Rhode Island State Republic and Providence Plantations." According to the site, Bey served in the military for four years, some or all of that time in the Marines, after which he began studying "Moorish Science."

That website, "Rise of the Moors," explains that Moors are not "sovereign citizens" because "sovereignty does not stand alone," but can rather be considered synonymous with "nationality."

"The record show that the Moors are the organic or original sovereigns of this land — America," the FAQ says. "When we declare our nationality as Moorish Americans we are taking back the position as the aboriginal people of the land, to which the sovereign power is vested in."

Bey's group may be associated with the Moorish sovereign citizen movement, which the Southern Poverty Law Center characterizes as an offshoot of the antigovernment sovereign citizens movement. Moorish sovereigns "have come into conflict with federal and state authorities over their refusal to obey laws and government regulations," SPLC writes.

"The Moorish Sovereign movement is a rapidly growing group of people who believe that they belong to a sovereign nation that has a treaty with the US but otherwise operates outside of the federal and state laws," JJ MacNab, a fellow at George Washington University's Program on Extremism, explained on Twitter.

"They rely on an alternative history that borrows from Moorish Science Temple, Black Hebrew Israelism, Nation of Islam, UFO theories, phony Native American tribes, and the pseudo-legal arguments crafted by white supremacist 'patriot' groups in the 1970s," MacNab said.
