Sorghum, a short-day tropical plant, has been adapted for temperate grain production, in particular through the selection of variants at the MATURITY loci (Ma1–Ma6) that reduce photoperiod sensitivity. Ma3 encodes phytochrome B (phyB), a red/far-red photochromic biliprotein photoreceptor. The multi-domain gene product, comprising 1178 amino acids, autocatalytically binds the phytochromobilin chromophore to form the photoactive holophytochrome (Sb.phyB). This study describes the development of an efficient heterologous overproduction system which allows the production of large quantities of various holoprotein constructs, along with purification and crystallization procedures. Crystals of the Pr (red-light-absorbing) forms of NPGP, PGP and PG (residues 1–655, 114–655 and 114–458, respectively), each C-terminally tagged with His6, were successfully produced. While NPGP crystals did not diffract, those of PGP and PG diffracted to 6 and 2.1 Å resolution, respectively. Moving the tag to the N-terminus and replacing phytochromobilin with phycocyanobilin as the ligand produced PG crystals that diffracted to 1.8 Å resolution. These results demonstrate that the diffraction quality of challenging protein crystals can be improved by removing flexible regions, shifting fusion tags and altering small-molecule ligands.

Combined 100 ms resolved grazing-incidence small/wide-angle X-ray scattering and optical interferometry reveal that the additive diiodooctane can significantly double the solvent evaporation rate, thereby effectively suppressing the rapid spinodal decomposition process in the early stage of spin-coasting, favouring slow phase segregation kinetics with nucleation and growth.

This study proposes an operation optimization framework for impurity-free recycling of spent lithium-ion batteries. Using a hybrid population balance equation integrated with a data-driven condition classifier, the study firstly identifies the optimal batch and semi-batch operation conditions that significantly reduce the operation time with 100% purity of product; detailed guidelines are given for industrial applications.

The crystal structure of the co-crystal salt solvate 1,10-phenanthrolinium violurate violuric acid penta­hydrate features a tri-periodic hydrogen-bonded network with the violurate and violuric acid residues each assembled into tapes and the phenanthrolinium cations residing in channels.

Calculations and measurements of polarization-dependent soft X-ray scattering intensity are presented during a magnetic hysteresis cycle. It is confirmed that the dependence of the intensity on the magnetic moment can be linear, quadratic or a combination of both, depending on the polarization of the incident X-ray beam and the direction of the magnetic moment. With a linearly polarized beam, the scattered intensity will have a purely quadratic dependence on the magnetic moment when the magnetic moment is parallel to the scattering plane. However, with the magnetic moment perpendicular to the scattering plane, there is also a linear component. This means that, when measuring the hysteresis with linear polarization during a hysteresis cycle, the intensity will be an even function of the applied field when the change in the magnetic moment (and field) is confined within the scattering plane but becomes more complicated when the magnetic moment is out of the scattering plane. Furthermore, with circular polarization, the dependence of the scattered intensity on the moment is a combination of linear and quadratic. With the moment parallel to the scattering plane, the linear component changes with the helicity of the incident beam. Surprisingly, in stark contrast to absorption studies, even when the magnetic moment is perpendicular to the scattering plane there is still a dependence on the moment with a linear component. This linear component is completely independent of the helicity of the beam, meaning that the hysteresis loops will not be inverted with helicity.

Improving the scalability of tissue imaging throughput with bright, coherent X-rays requires identifying and mitigating artifacts resulting from the interactions between X-rays and matter. At synchrotron sources, long-term imaging of soft tissues in solution can result in gas bubble formation or cavitation, which dramatically compromises image quality and integrity of the samples. By combining in-line phase-contrast imaging with gas chromatography in real time, we were able to track the onset and evolution of high-energy X-ray-induced gas bubbles in ethanol-embedded soft tissue samples for tens of minutes (two to three times the typical scan times). We demonstrate quantitatively that vacuum degassing of the sample during preparation can significantly delay bubble formation, offering up to a twofold improvement in dose tolerance, depending on the tissue type. However, once nucleated, bubble growth is faster in degassed than undegassed samples, indicating their distinct metastable states at bubble onset. Gas chromatography analysis shows increased solvent vaporization concurrent with bubble formation, yet the quantities of dissolved gasses remain unchanged. By coupling features extracted from the radiographs with computational analysis of bubble characteristics, we uncover dose-controlled kinetics and nucleation site-specific growth. These hallmark signatures provide quantitative constraints on the driving mechanisms of bubble formation and growth. Overall, the observations highlight bubble formation as a critical yet often overlooked hurdle in upscaling X-ray imaging for biological tissues and soft materials and we offer an empirical foundation for their understanding and imaging protocol optimization. More importantly, our approaches establish a top-down scheme to decipher the complex, multiscale radiation–matter interactions in these applications.

Synchrotron light sources require X-ray optics with extremely demanding accuracy for the surface profile, with less than 100 nrad slope errors and sub-nanometre height errors. Such errors are challenging to achieve for aspheres using traditional polishing methods. However, post-polishing error correction can be performed using techniques such as ion beam figuring (IBF) to improve optics to the desired quality. This work presents a brief overview of the history of IBF, introduces some of the challenges for obtaining such demanding figure errors, and highlights the work done at several in-house IBF facilities at synchrotron light sources worldwide to obtain state-of-the-art optical quality.

Ion beam figuring (IBF) is a powerful technique for figure correction of X-ray mirrors to a high accuracy. Here, recent technical advancements in the IBF instrument developed at Diamond Light Source are presented and experimental results for figuring of X-ray mirrors are given. The IBF system is equipped with a stable DC gridded ion source (120 mm diameter), a four-axis motion stage to manipulate the optic, a Faraday cup to monitor the ion-beam current, and a camera for alignment. A novel laser speckle angular measurement instrument also provides on-board metrology. To demonstrate the IBF system's capabilities, two silicon X-ray mirrors were processed. For 1D correction, a height error of 0.08 nm r.m.s. and a slope error of 44 nrad r.m.s. were achieved. For 2D correction over a 67 mm × 17 mm clear aperture, a height error of 0.8 nm r.m.s. and a slope error of 230 nrad r.m.s. were obtained. For the 1D case, this optical quality is comparable with the highest-grade, commercially available, X-ray optics.

The validation of structural models obtained by macromolecular X-ray crystallography against experimental diffraction data, whether before deposition into the PDB or after, is typically carried out exclusively against the merged data that are eventually archived along with the atomic coordinates. It is shown here that the availability of unmerged reflection data enables valuable additional analyses to be performed that yield improvements in the final models, and tools are presented to implement them, together with examples of the results to which they give access. The first example is the automatic identification and removal of image ranges affected by loss of crystal centering or by excessive decay of the diffraction pattern as a result of radiation damage. The second example is the `reflection-auditing' process, whereby individual merged data items showing especially poor agreement with model predictions during refinement are investigated thanks to the specific metadata (such as image number and detector position) that are available for the corresponding unmerged data, potentially revealing previously undiagnosed instrumental, experimental or processing problems. The third example is the calculation of so-called F(early) − F(late) maps from carefully selected subsets of unmerged amplitude data, which can not only highlight the location and extent of radiation damage but can also provide guidance towards suitable fine-grained parametrizations to model the localized effects of such damage.

In the search for new active pharmaceutical ingredients, the precise control of the chemistry of cocrystals becomes essential. One crucial step within this chemistry is proton migration between cocrystal coformers to form a salt, usually anticipated by the empirical ΔpKa rule. Due to the effective role it plays in modifying intermolecular distances and interactions, pressure adds a new dimension to the ΔpKa rule. Still, this variable has been scarcely applied to induce proton-transfer reactions within these systems. In our study, high-pressure X-ray diffraction and Raman spectroscopy experiments, supported by DFT calculations, reveal modifications to the protonation states of the 4,4'-bi­pyridine (BIPY) and malonic acid (MA) cocrystal (BIPYMA) that allow the conversion of the cocrystal phase into ionic salt polymorphs. On compression, neutral BIPYMA and monoprotonated (BIPYH+MA−) species coexist up to 3.1 GPa, where a phase transition to a structure of P21/c symmetry occurs, induced by a double proton-transfer reaction forming BIPYH22+MA2−. The low-pressure C2/c phase is recovered at 2.4 GPa on decompression, leading to a 0.7 GPa hysteresis pressure range. This is one of a few studies on proton transfer in multicomponent crystals that shows how susceptible the interconversion between differently charged species is to even slight pressure changes, and how the proton transfer can be a triggering factor leading to changes in the crystal symmetry. These new data, coupled with information from previous reports on proton-transfer reactions between coformers, extend the applicability of the ΔpKa rule incorporating the pressure required to induce salt formation.

Light–oxygen–voltage (LOV) domains are small photosensory flavoprotein modules that allow the conversion of external stimuli (sunlight) into intra­cellular signals responsible for various cell behaviors (e.g. phototropism and chloro­plast relocation). This ability relies on the light-induced formation of a covalent thio­ether adduct between a flavin chromophore and a reactive cysteine from the protein environment, which triggers a cascade of structural changes that result in the activation of a serine/threonine (Ser/Thr) kinase. Recent developments in time-resolved crystallography may allow the activation cascade of the LOV domain to be observed in real time, which has been elusive. In this study, we report a robust protocol for the production and stable delivery of microcrystals of the LOV domain of phototropin Phot-1 from Chlamydomonas reinhardtii (CrPhotLOV1) with a high-viscosity injector for time-resolved serial synchrotron crystallography (TR-SSX). The detailed process covers all aspects, from sample optimization to data collection, which may serve as a guide for soluble protein preparation for TR-SSX. In addition, we show that the crystals obtained preserve the photoreactivity using infrared spectroscopy. Furthermore, the results of the TR-SSX experiment provide high-resolution insights into structural alterations of CrPhotLOV1 from Δt = 2.5 ms up to Δt = 95 ms post-photoactivation, including resolving the geometry of the thio­ether adduct and the C-terminal region implicated in the signal transduction process.

The structures of three multicomponent crystals formed with imidazole-based drugs, namely metronidazole, ketoconazole and miconazole, in conjunction with tri­thio­cyanuric acid are characterized. Each of the obtained adducts represents a different category of crystalline molecular forms: a cocrystal, a salt and a cocrystal of salt. The structural analysis revealed that in all cases, the N—H⋯N hydrogen bond is responsible for the formation of acid–base pairs, regardless of whether proton transfer occurs or not, and these molecular pairs are combined to form unique supramolecular motifs by centrosymmetric N—H⋯S interactions between acid molecules. The complex intermolecular forces acting in characteristic patterns are discussed from the geometric and energetic perspectives, involving Hirshfeld surface analysis, pairwise energy estimation, and natural bond orbital calculations.

A new mononuclear complex, penta­aqua­(cucurbit[6]uril-κ2O,O')(nitrato-κ2O,O')praseodymium(III) dinitrate 9.56-hydrate, [Pr(NO3)(CB6)(H2O)5](NO3)2·9.56H2O (1), was obtained as outcome of the hydro­thermal reaction between the macrocyclic ligand cucurbit[6]uril (CB6, C36H36N24O12) with a tenfold excess of Pr(NO3)3·6H2O. Complex 1 crystallizes in the P21/n space group with two crystallographically independent but chemically identical [Pr(CB6)(NO3)(H2O)5]2+ complex cations, four nitrate counter-anions and 19.12 inter­stitial water mol­ecules per asymmetric unit. The nona­coordinated PrIII in 1 are located in the PrO9 coordination environment formed by two carbonyl O atoms from bidentate cucurbit[6]uril units, two oxygen atoms from the bidentate nitrate anion and five water mol­ecules. Considering the differences in Pr—O bond distances and O—Pr—O angles in the coordination spheres, the coordination polyhedrons of the two PrIII atoms can be described as distorted spherical capped square anti­prismatic and muffin polyhedral.

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.

Polymer-derived ceramics (PDCs) remain at the forefront of research for a variety of applications including ultra-high-temperature ceramics, energy storage and functional coatings. Despite their wide use, questions remain about the complex structural transition from polymer to ceramic and how local structure influences the final microstructure and resulting properties. This is further complicated when nanofillers are introduced to tailor structural and functional properties, as nanoparticle surfaces can interact with the matrix and influence the resulting structure. The inclusion of crystalline nanofiller produces a mixed crystalline–amorphous composite, which poses characterization challenges. With this study, we aim to address these challenges with a local-scale structural study that probes changes in a polysiloxane matrix with incorporated copper nanofiller. Composites were processed at three unique temperatures to capture mixing, pyrolysis and initial crystallization stages for the pre-ceramic polymer. We observed the evolution of the nanofiller with electron microscopy and applied synchrotron X-ray diffraction with differential pair distribution function (d-PDF) analysis to monitor changes in the matrix's local structure and interactions with the nanofiller. The application of the d-PDF to PDC materials is novel and informs future studies to understand interfacial interactions between nanofiller and matrix throughout PDC processing.

Energy-dispersive Laue diffraction (EDLD) is a powerful method to obtain position-resolved texture information in inhomogeneous biological samples without the need for sample rotation. This study employs EDLD texture scanning to investigate the impact of two salivary peptides, statherin (STN) and histatin-1 (HTN) 21 N-terminal peptides (STN21 and HTN21), on the crystallographic structure of dental enamel. These proteins are known to play crucial roles in dental caries progression. Three healthy incisors were randomly assigned to three groups: artificially demineralized, demineralized after HTN21 peptide pre-treatment and demineralized after STN21 peptide pre-treatment. To understand the micro-scale structure of the enamel, each specimen was scanned from the enamel surface to a depth of 250 µm using microbeam EDLD. Via the use of a white beam and a pixelated detector, where each pixel functions as a spectrometer, pole figures were obtained in a single exposure at each measurement point. The results revealed distinct orientations of hydroxyapatite crystallites and notable texture variation in the peptide-treated demineralized samples compared with the demineralized control. Specifically, the peptide-treated demineralized samples exhibited up to three orientation populations, in contrast to the demineralized control which displayed only a single orientation population. The texture index of the demineralized control (2.00 ± 0.21) was found to be lower than that of either the STN21 (2.32 ± 0.20) or the HTN21 (2.90 ± 0.46) treated samples. Hence, texture scanning with EDLD gives new insights into dental enamel crystallite orientation and links the present understanding of enamel demineralization to the underlying crystalline texture. For the first time, the feasibility of EDLD texture measurements for quantitative texture evaluation in demineralized dental enamel samples is demonstrated.

Zilch, a fintech company operating an ad-subsidised payments...

The National Bank of Cambodia (NBC) has announced the launch of the Bakong Tourists App with Mastercard, with the institution aiming to optimise digital payments for tourists visiting Cambodia. 

The pandemic has taken a massive toll on people's mental health. But a new report by the U.S. Centers for Disease Control and Prevention confirms what many of us are seeing and feeling in our own lives: The impact has been particularly devastating for parents and unpaid caregivers of adults.

Two-thirds of survey respondents who identified as unpaid caregivers said they experienced mental health challenges during the pandemic, such as symptoms of anxiety or depression, or suicidal thoughts.

Only one-third of people with no caregiving responsibilities reported the same symptoms.

Of the more than 10,000 survey respondents, more than 40% identified as being unpaid caregivers.

"What is striking here is just how widespread unpaid caregiving responsibilities are in the population and how much of a burden and a toll these responsibilities" are having, says Shantha Rajaratnam, a co-author of the study and a psychologist at the Turner Institute of Brain and Mental Health at Monash University in Australia.

The study also found that people who care for both children under 18 and adults — many of them part of the sandwich generation — are faring the worst, with 85% of this group experiencing adverse mental health symptoms.

"It's an extremely important study," says psychologist Dolores Gallagher-Thompson, professor emeritus at Stanford University who has researched family caregivers and their challenges.

The study is the first to document the problems caregivers have experienced during COVID-19, she notes, and underscores "the importance of paying attention to caregiver issues, caregiver mental health" and the need for education and resources to better support them.

The contrast between caregivers and others is stark

The study, part of ongoing research by The COVID-19 Outbreak Public Evaluation (COPE) Initiative, is based on surveys conducted in December 2020 and February-March 2021.

More than half of those who identified as caregivers said they had experienced symptoms of anxiety or depression, or of disorders like PTSD related to the stress and trauma of COVID-19.

A significant number of caregivers said they had contemplated suicide. Nearly 40% reported having passive suicidal thoughts, meaning "wishing that they had gone to bed and didn't wake up," says study co-author Mark Czeisler, a graduate student at Monash University and a research trainee at Brigham and Women's Hospital in Boston.

And more than 30% had seriously considered taking their own life — about five times the number of noncaregivers, the study found.

Across the board, mental health impacts have been more severe for people who care for both children and adults. Half of this group said it had seriously considered suicide in the past month.

The pandemic worsened the challenges caregivers face

Even before the pandemic, being an unpaid caregiver was stressful and associated with a higher risk of mental health issues, says Gallagher-Thompson. The COVID-19 pandemic has made things even harder.

For instance, the pandemic has taken away many formal and informal sources of support for caregivers.

That was the case for Dr. Nicole Christian-Brathwaite. She's a Boston-based child psychiatrist and lives with her husband, her mother, her husband's father and two sons, who are 4 and 6.

Before the pandemic, her father-in-law, who has dementia, went to a day program for seniors with cognitive decline. Her mother, a survivor of breast and lung cancers, went to physical therapy twice a week, doctor appointments and met with friends.

When the pandemic hit, they lost those services and social support — at the same time Christian-Brathwaite and her husband began working from home while taking care of their sons and parents.

Life at home became much more complicated. Her sons developed behavioral problems with the transitions and stresses of the pandemic. Her mother struggled with chronic pain, and was hospitalized during the pandemic. And there were days when her father-in-law was confused, disoriented or aggressive.

"Many days I was walking around on edge waiting for something to happen because our entire setup was so very fragile and vulnerable," says Christian-Brathwaite. "It's been exhausting."

And her mental health has suffered. "I certainly was dealing with insomnia," she says. "I was short tempered. I was more irritable. I didn't have the same tolerance for things."

More support needed to help caregivers cope

The new study highlights the extent to which unpaid caregivers have struggled during the pandemic, says Gallagher-Thompson.

"There are some serious issues here that shouldn't be ignored," she says.

And yet caregivers are often ignored by the health system, which is set up to focus only on patients.

"Family members are rarely asked, 'How does this affect you? What is difficult? How can we help you? How can we support you in being able to carry out your role, your tasks, your responsibilities?'" Gallagher-Thompson says.

As the new study shows, support can make a big difference — respondents who could rely on others for help with caregiving had a lower incidence of mental health symptoms.

So it's important to educate and support caregivers. For example, physicians can start by screening their patients' caregivers for mental health symptoms and provide more resources to those who need it, says Gallagher-Thompson.

Christian-Brathwaite hopes the new study will help physicians recognize that family caregivers are just as important to consider while treating patients.

"We really need to take a step back and look at the village that's around them because our patients can't be successful without having the support from family," she says.

For the last month, Frank Galaviz has wondered when running water will return to his town.

The 77-year-old resident of Teviston — a small rural community in Central California — has been forced to depend on stored and bottled water after the pump in the town's only functioning well broke down in early June. Since then, residents have had to travel to neighboring towns to shower or depend on the town's water storage tanks for their daily needs.

Temperatures continue to reach into triple digits as a brutal heat wave sweeps across the West Coast. The ongoing drought only exacerbates the problem, Galaviz says.

"[My wife and I] have lived through many challenges," he says. "We both have survived cancer, but we will not be able to survive without water. This is a problem that is not going away."

Teviston sits between the cities of Fresno and Bakersfield in the San Joaquin Valley and is home to mostly Latino farmworkers. Normal days in town are usually slow-paced and idyllic, Galaviz says, with many residents commuting to the nearby towns and cities on business. Now, they leave to find more water.

This is not the first time Galaviz or his neighbors have struggled with a broken well. He says two other wells had broken down in previous years and had not been repaired. A new, more modern well is in the works, but Galaviz estimates its completion is still a few years off.

The community continues waiting for repair parts to arrive in hopes it will fix the current well's pump, he added, a process that could take a few weeks.

"It is not normal to not be able to flush toilets," he says. "It's not normal to not be able to take a shower."

Residents have managed to come up with a temporary fix, using their water storage tanks to offer relief.

"We were able to get some of the water pressure back," Galaviz said. "We put a submersible pump into one of our old wells and we're forcing water from the storage tanks through that system. But it's not a permanent fix."

Rural Latino communities in California have been particularly vulnerable to drought conditions, according to a report from the state Legislative Analyst's Office.

"Having no water equals bad health," state Sen. Melissa Hurtado, who serves California's 14th District, tells Weekend Edition. Hurtado says her bill, SB 559, would allot $785 million to fund and repair water supply infrastructure. One of the waterways posed for fixing is the Friant-Kern canal, which supplies Teviston and the towns around it. Over the years, the canal has become subject to subsidence — a condition that has caused some parts of the canal to sink and means it can't deliver as much water.

"SB 559 would help fix the canal so that the basin and the communities that rely on water here would be able to have more access to it," Hurtado says.

Galaviz has spent the last few weeks knocking on doors to check in on neighbors and trying to organize help.

"I have a neighbor whose daughter has medical problems. She needs drinking water, pure water," he says. "It hurts to see people suffering."
