Economist Vladislav Inozemtsev writes about the change in the leadership of the Federal Chamber of Lawyers “At the end of last week ... at a meeting of the Council of the Federal Chamber of Lawyers of Russia, its long-term president, Yuri Pilipenko, who has held this post since 2015, was not re-elected for another term. (It is noteworthy that on the morning of December 15, he, being a president of the Chamber, sent a letter to the head of the Council of Bars and Law Societies of Europe, James MacGuill, expressing concern about the situation with the protection of the legal rights of Russians in European countries).” Inozemtsev notes that Pilipenko is a “highly experienced lawyer” who, as it would seem, “talentedly led a professional organization of lawyers, skillfully resolving any sensitive issues in the interaction between the legal community and the authorities, and at the same time demonstrating a willingness to independently make important decisions for the legal workers without waiting for the initiatives of the Ministry of Justice and the Kremlin.”

Monoclinic ferroelectric phases are prevalent in various functional materials, most notably mixed-ion perovskite oxides. These phases can manifest as regularly ordered long-range crystallographic structures or as macroscopic averages of the self-assembled tetragonal/rhombohedral nanodomains. The structural and physical properties of monoclinic ferroelectric phases play a pivotal role when exploring the interplay between ferroelectricity, ferroelasticity, giant piezoelectricity and multiferroicity in crystals, ceramics and epitaxial thin films. However, the complex nature of this subject presents challenges, particularly in deciphering the microstructures of monoclinic domains. In Paper I [Biran & Gorfman (2024). Acta Cryst. A80, 112–128] the geometrical principles governing the connection of domain microstructures formed by pairing MAB type monoclinic domains were elucidated. Specifically, a catalog was established of `permissible domain walls', where `permissible', as originally introduced by Fousek & Janovec [J. Appl. Phys. (1969), 40, 135–142], denotes a mismatch-free connection between two monoclinic domains along the corresponding domain wall. The present article continues the prior work by elaborating on the formalisms of permissible domain walls to describe domain microstructures formed by pairing the MC type monoclinic domains. Similarly to Paper I, 84 permissible domain walls are presented for MC type domains. Each permissible domain wall is characterized by Miller indices, the transformation matrix between the crystallographic basis vectors of the domains and, crucially, the expected separation of Bragg peaks diffracted from the matched pair of domains. All these parameters are provided in an analytical form for easy and intuitive interpretation of the results. Additionally, 2D illustrations are provided for selected instances of permissible domain walls. The findings can prove valuable for various domain-related calculations, investigations involving X-ray diffraction for domain analysis and the description of domain-related physical properties.

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.

The influence of the crystal synthesis method on the crystallographic structure of caffeine–citric acid co­crystals was analyzed thanks to the synthesis of a new polymorphic form of the cocrystal. In order to com­pare the new form to the already known forms, the crystal structure of the new cocrystal (C8H10N4O2·C6H8O7) was solved by powder X-ray diffraction thanks to synchrotron experiments. The structure determination was performed using `GALLOP', a recently developed hybrid approach based on a local optimization with a particle swarm optimizer, particularly powerful when applied to the structure resolution of materials of pharmaceutical inter­est, com­pared to classical Monte-Carlo simulated annealing. The final structure was obtained through Rietveld refinement, and first-principles density functional theory (DFT) calculations were used to locate the H atoms. The symmetry is triclinic with the space group Poverline{1} and contains one mol­ecule of caffeine and one mol­ecule of citric acid per asymmetric unit. The crystallographic structure of this cocrystal involves different hydrogen-bond associations com­pared to the already known structures. The analysis of these hydrogen bonds indicates that the cocrystal obtained here is less stable than the co­crystals already identified in the literature. This analysis is confirmed by the determination of the melting point of this cocrystal, which is lower than that of the previously known co­crystals.

Single-particle cryo-electron microscopy has become a widely adopted method in structural biology due to many recent technological advances in microscopes, detectors and image processing. Before being able to inspect a biological sample in an electron microscope, it needs to be deposited in a thin layer on a grid and rapidly frozen. The VitroJet was designed with this aim, as well as avoiding the delicate manual handling and transfer steps that occur during the conventional grid-preparation process. Since its creation, numerous technical developments have resulted in a device that is now widely utilized in multiple laboratories worldwide. It features plasma treatment, low-volume sample deposition through pin printing, optical ice-thickness measurement and cryofixation of pre-clipped Autogrids through jet vitrification. This paper presents recent technical improvements to the VitroJet and the benefits that it brings to the cryo-EM workflow. A wide variety of applications are shown: membrane proteins, nucleosomes, fatty-acid synthase, Tobacco mosaic virus, lipid nanoparticles, tick-borne encephalitis viruses and bacteriophages. These case studies illustrate the advancement of the VitroJet into an instrument that enables accurate control and reproducibility, demonstrating its suitability for time-efficient cryo-EM structure determination.

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.

A few real case examples are presented on how to report magnetic structures, with precise step-by-step explanations, following the guidelines of the IUCr Commission on Magnetic Structures [Perez-Mato et al. (2024). Acta Cryst. B80, 219–234]. Four examples have been chosen, illustrating different types of single-k magnetic orders, from the basic case to more complex ones, including odd-harmonics, and one multi-k order. In addition to acquainting researchers with the process of communicating commensurate magnetic structures, these examples also aim to clarify important concepts, which are used throughout the guidelines, such as the transformation to a standard setting of a magnetic space group.

Controlling the shape and size dispersivity and crystallinity of nanoparticles (NPs) has been a challenge in identifying these parameters' role in the physical and chemical properties of NPs. The need for reliable quantitative tools for analyzing the dispersivity and crystallinity of NPs is a considerable problem in optimizing scalable synthesis routes capable of controlling NP properties. The most common tools are electron microscopy (EM) and X-ray scattering techniques. However, each technique has different susceptibility to these parameters, implying that more than one technique is necessary to characterize NP systems with maximum reliability. Wide-angle X-ray scattering (WAXS) is mandatory to access information on crystallinity. In contrast, EM or small-angle X-ray scattering (SAXS) is required to access information on whole NP sizes. EM provides average values on relatively small ensembles in contrast to the bulk values accessed by X-ray techniques. Besides the fact that the SAXS and WAXS techniques have different susceptibilities to size distributions, SAXS is easily affected by NP–NP interaction distances. Because of all the variables involved, there have yet to be proposed methodologies for cross-analyzing data from two techniques that can provide reliable quantitative results of dispersivity and crystallinity. In this work, a SAXS/WAXS-based methodology is proposed for simultaneously quantifying size distribution and degree of crystallinity of NPs. The most reliable easy-to-access size result for each technique is demonstrated by computer simulation. Strategies on how to compare these results and how to identify NP–NP interaction effects underneath the SAXS intensity curve are presented. Experimental results are shown for cubic-like CeO2 NPs. WAXS size results from two analytical procedures are compared, line-profile fitting of individual diffraction peaks in opposition to whole pattern fitting. The impact of shape dispersivity is also evaluated. Extension of the proposed methodology for cross-analyzing EM and WAXS data is possible.

Structural modelling of operando pair distribution function (PDF) data of complex functional materials can be highly challenging. To aid the understanding of complex operando PDF data, this article demonstrates a toolbox for PDF analysis. The tools include denoising using principal component analysis together with the structureMining, similarityMapping and nmfMapping apps available through the online service `PDF in the cloud' (PDFitc, https://pdfitc.org/). The toolbox is used for both ex situ and operando PDF data for 3 nm TiO2-bronze nanocrystals, which function as the active electrode material in a Li-ion battery. The tools enable structural modelling of the ex situ and operando PDF data, revealing two pristine TiO2 phases (bronze and anatase) and two lithiated LixTiO2 phases (lithiated versions of bronze and anatase), and the phase evolution during galvanostatic cycling is characterized.

The same artificial intelligence technique typically used in facial recognition systems could help improve prediction of hailstorms and their severity, according to a new, National Science Foundation-funded study. Instead of zeroing in on the features of an individual face, scientists trained a deep learning model called a convolutional neural network to recognize features of individual storms that affect the formation of hail and how large the hailstones will be, both of which are notoriously difficult to predict. The promising results highlight the importance of taking into account a storm's entire structure, something that's been challenging to do with existing hail-forecasting techniques.

According to the National Institute For Early Childhood Research, nearly half of all three-year-olds and a third of all four-year-olds in the United States were not enrolled in preschool in 2019. That's in large part because many parents can't afford it. Imagine a future where we changed that. A future where every American child had access to two years of preschool during a critical period of their mental development. How would their lives change? How would society change? If President Biden gets his way, and Congress agrees to spend $200 billion on his proposal for universal preschool, then we may begin to find out.

But it turns out, we kind of already know. In fact, a new study from the National Bureau of Economic Research gives us a glimpse of what that world could look like. It adds to a burgeoning amount of high-quality research that shows just how valuable preschool is — and maybe not for the reasons you might think.

An Accidental Experiment

The story begins back in the mid-to-late 1990s. The Mayor of Boston, Thomas Menino, wanted to improve the city's schools. One of his big goals was to provide universal, full-day kindergarten for Boston's kids. But the budget was tight, and following a task force's recommendations, he and local lawmakers decided to move resources from preschool (for four-year-olds) to kindergarten (for five-year-olds) in order to achieve it.

The result was an even more limited number of slots for city-funded preschool, and the city officials had to figure out how to fairly divvy up those slots. They resorted to a lottery system, randomly selecting kids who would get in.

Fast forward two decades later, and the economists Christopher R. Walters, Guthrie Gray-Lobe, and Parag A. Pathak saw this as a golden opportunity to see how preschool can affect people's lives. The fact that Boston's school administrators randomized who got admitted meant there were two virtually identical groups of kids with only one difference: one group got an extra year of education by going to preschool. That gave the researchers the opportunity to compare and contrast the two groups of kids and credibly see how kids' lives changed as a result of getting into preschool.

Four thousand four-year-olds took part in Boston's preschool lottery between 1997 and 2003. Walters, Gray-Lobe, and Pathak acquired data on them from the Boston school system. And then they were able to get additional data from other sources that gave them insight into ways that the childrens' lives might have benefited from an additional year of preschool education. These kids are now all twentysomethings — a fact that should make you feel old.

Consistent with other studies that find preschool has a huge effect on kids, Walters, Gray-Lobe, and Pathak find that the kids lucky enough to get accepted into preschools in Boston saw meaningful changes to their lives. These kids were less likely to get suspended from school, less likely to skip class, and less likely to get in trouble and be placed in a juvenile detention facility. They were more likely to take the SATs and prepare for college.

The most eye-popping effects the researchers find are on high school graduation and college enrollment rates. The kids who got accepted into preschool ended up having a high-school graduation rate of 70% — six percentage points higher than the kids who were denied preschool, who saw a graduation rate of only 64%. And 54% of the preschoolers ended up going to college after they graduated — eight percentage points higher than their counterparts who didn't go to preschool. These effects were bigger for boys than for girls. And they're all the more remarkable because the researchers only looked at the effects of a single year of preschool, as opposed to two years of preschool (as President Biden is now proposing for the nation's youth). Moreover, in many cases, the classes were only half-day.

Intriguingly, while attending preschool at age four had clear effects on these kids' entire lives, it did not improve their performance on standardized tests. These findings fit into a large body of research that suggests the true value of preschool is helping little ones to develop "non-cognitive skills," like emotional and social intelligence, grit, and respect for the rules.

"The combination of findings — that we don't see an impact on test scores, but we do see an impact on these behavioral outcomes and the likelihood of attending college — is consistent with this idea that there's some kind of behavioral or socio-emotional, non-cognitive impact from preschool," says Christopher Walters, an economist at UC Berkeley who co-authored the study.

In other words, there's growing evidence that preschool can permanently improve kids lives — but it's not necessarily because it makes them smarter. It seems more related to making them more disciplined and motivated, which is just as important (or perhaps even more important) for their future livelihoods as how well they perform on reading or math tests.

The Bigger Picture

This latest study isn't the first to show the outsized effects of providing a preschool education. The Nobel Prize-winning economist James Heckman has spent many years studying the results of small, randomized experiments with preschool in the 1960s and 1970s. The most famous such experiment was The Perry Preschool Project, which was conducted in Ypsilanti, Michigan. The program provided two years of high-quality preschool for disadvantaged three- and four-year-olds.

Heckman and his colleagues found that the Perry Preschool had seismic effects on the kids who participated. They were much less likely to get arrested, go on welfare, or be unemployed as adults. They earned significantly more. In a recent study, Heckman and his team found that even the kids of the kids who went to the Perry preschool had significantly better outcomes in life.

All in all, Heckman and his team estimate that every dollar the Perry Preschool project invested in kids had a return on investment of 7-10 percent per year, through increased economic gains for the kids and decreased public spending on them through other social programs when they got older. That's a substantial return, equal to or greater than the average annual return from the stock market, and much greater than most other things our government spends money on.

Other preschool programs studied by Heckman and his colleagues have had even greater benefits. In the 1970s, a couple of programs in North Carolina experimented with high-quality childcare centers for kids. The centers offered kids aged zero to five education, medical checkups, and nutritious food. Heckman and his team found these centers delivered a 13 percent annual return on investment to the public for every dollar they invested. The program helped Heckman develop what's known as "the Heckman Curve," which asserts that the government gets more bang for the buck the earlier it provides resources to educate people. Educating toddlers, Heckman says, is much more powerful than educating high-schoolers, college students, or adults in, for example, job-training programs.

As astounding as Heckman's findings about preschool have been, naysayers have long questioned whether such effects could be replicated with larger scale programs, like the one President Biden is now proposing. This new study out of Boston, which looks at a large-scale program conducted across the entire city, is another brick in the growing edifice of evidence that shows preschool is a worthy investment, not just for kids, but for society overall.
