The results of the seventh blind test of crystal structure prediction are presented, focusing on structure generation methods.

The results of the seventh blind test of crystal structure prediction are presented, focusing on structure ranking methods.

Accurate modeling of conformational energies is key to the crystal structure prediction of conformational polymorphs. Focusing on molecules XXXI and XXXII from the seventh blind test of crystal structure prediction, this study employs various electronic structure methods up to the level of domain-local pair natural orbital coupled cluster singles and doubles with perturbative triples [DLPNO-CCSD(T1)] to benchmark the conformational energies and to assess their impact on the crystal energy landscapes. Molecule XXXI proves to be a relatively straightforward case, with the conformational energies from generalized gradient approximation (GGA) functional B86bPBE-XDM changing only modestly when using more advanced density functionals such as PBE0-D4, ωB97M-V, and revDSD-PBEP86-D4, dispersion-corrected second-order Møller–Plesset perturbation theory (SCS-MP2D), or DLPNO-CCSD(T1). In contrast, the conformational energies of molecule XXXII prove difficult to determine reliably, and variations in the computed conformational energies appreciably impact the crystal energy landscape. Even high-level methods such as revDSD-PBEP86-D4 and SCS-MP2D exhibit significant disagreements with the DLPNO-CCSD(T1) benchmarks for molecule XXXII, highlighting the difficulty of predicting conformational energies for complex, drug-like molecules. The best-converged predicted crystal energy landscape obtained here for molecule XXXII disagrees significantly with what has been inferred about the solid-form landscape experimentally. The identified limitations of the calculations are probably insufficient to account for the discrepancies between theory and experiment on molecule XXXII, and further investigation of the experimental solid-form landscape would be valuable. Finally, assessment of several semi-empirical methods finds r2SCAN-3c to be the most promising, with conformational energy accuracy intermediate between the GGA and hybrid functionals and a low computational cost.

The seventh blind test of crystal structure prediction (CSP) methods substantially increased the level of complexity of the target compounds relative to the previous tests organized by the Cambridge Crystallographic Data Centre. In this work, the performance of density-functional methods is assessed using numerical atomic orbitals and the exchange-hole dipole moment dispersion correction (XDM) for the energy-ranking phase of the seventh blind test. Overall, excellent performance was seen for the two rigid molecules (XXVII, XXVIII) and for the organic salt (XXXIII). However, for the agrochemical (XXXI) and pharmaceutical (XXXII) targets, the experimental polymorphs were ranked fairly high in energy amongst the provided candidate structures and inclusion of thermal free-energy corrections from the lattice vibrations was found to be essential for compound XXXI. Based on these results, it is proposed that the importance of vibrational free-energy corrections increases with the number of rotatable bonds.

A seventh blind test of crystal structure prediction has been organized by the Cambridge Crystallographic Data Centre. The results are presented in two parts, with this second part focusing on methods for ranking crystal structures in order of stability. The exercise involved standardized sets of structures seeded from a range of structure generation methods. Participants from 22 groups applied several periodic DFT-D methods, machine learned potentials, force fields derived from empirical data or quantum chemical calculations, and various combinations of the above. In addition, one non-energy-based scoring function was used. Results showed that periodic DFT-D methods overall agreed with experimental data within expected error margins, while one machine learned model, applying system-specific AIMnet potentials, agreed with experiment in many cases demonstrating promise as an efficient alternative to DFT-based methods. For target XXXII, a consensus was reached across periodic DFT methods, with consistently high predicted energies of experimental forms relative to the global minimum (above 4 kJ mol−1 at both low and ambient temperatures) suggesting a more stable polymorph is likely not yet observed. The calculation of free energies at ambient temperatures offered improvement of predictions only in some cases (for targets XXVII and XXXI). Several avenues for future research have been suggested, highlighting the need for greater efficiency considering the vast amounts of resources utilized in many cases.

A seventh blind test of crystal structure prediction was organized by the Cambridge Crystallographic Data Centre featuring seven target systems of varying complexity: a silicon and iodine-containing molecule, a copper coordination complex, a near-rigid molecule, a cocrystal, a polymorphic small agrochemical, a highly flexible polymorphic drug candidate, and a polymorphic morpholine salt. In this first of two parts focusing on structure generation methods, many crystal structure prediction (CSP) methods performed well for the small but flexible agrochemical compound, successfully reproducing the experimentally observed crystal structures, while few groups were successful for the systems of higher complexity. A powder X-ray diffraction (PXRD) assisted exercise demonstrated the use of CSP in successfully determining a crystal structure from a low-quality PXRD pattern. The use of CSP in the prediction of likely cocrystal stoichiometry was also explored, demonstrating multiple possible approaches. Crystallographic disorder emerged as an important theme throughout the test as both a challenge for analysis and a major achievement where two groups blindly predicted the existence of disorder for the first time. Additionally, large-scale comparisons of the sets of predicted crystal structures also showed that some methods yield sets that largely contain the same crystal structures.

The bulk solvent is a major component of biomacromolecular crystals that contributes significantly to the observed diffraction intensities. Accurate modelling of the bulk solvent has been recognized as important for many crystallographic calculations. Owing to its simplicity and modelling power, the flat (mask-based) bulk-solvent model is used by most modern crystallographic software packages to account for disordered solvent. In this model, the bulk-solvent contribution is defined by a binary mask and a scale (scattering) function. The mask is calculated on a regular grid using the atomic model coordinates and their chemical types. The grid step and two radii, solvent and shrinkage, are the three parameters that govern the mask calculation. They are highly correlated and their choice is a compromise between the computer time needed to calculate the mask and the accuracy of the mask. It is demonstrated here that this choice can be optimized using a unique value of 0.6 Å for the grid step irrespective of the data resolution, and the radii values adjusted correspondingly. The improved values were tested on a large sample of Protein Data Bank entries derived from X-ray diffraction data and are now used in the computational crystallography toolbox (CCTBX) and in Phenix as the default choice.

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.

TEMPUS is a new detector system being developed for photon science. It is based on the Timepix4 chip and, thus, it can be operated in two distinct modes: a photon-counting mode, which allows for conventional full-frame readout at rates up to 40 kfps; and an event-driven time-stamping mode, which allows excellent time resolution in the nanosecond regime in measurements with moderate X-ray flux. In this paper, the initial prototype, a single-chip device, is introduced, and the readout system described. Moreover, and in order to evaluate its capabilities, some tests were performed at PETRA III and ESRF for which results are also presented.

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

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

High-energy X-ray diffraction methods can non-destructively map the 3D microstructure and associated attributes of metallic polycrystalline engineering materials in their bulk form. These methods are often combined with external stimuli such as thermo-mechanical loading to take snapshots of the evolving microstructure and attributes over time. However, the extreme data volumes and the high costs of traditional data acquisition and reduction approaches pose a barrier to quickly extracting actionable insights and improving the temporal resolution of these snapshots. This article presents a fully automated technique capable of rapidly detecting the onset of plasticity in high-energy X-ray microscopy data. The technique is computationally faster by at least 50 times than the traditional approaches and works for data sets that are up to nine times sparser than a full data set. This new technique leverages self-supervised image representation learning and clustering to transform massive data sets into compact, semantic-rich representations of visually salient characteristics (e.g. peak shapes). These characteristics can rapidly indicate anomalous events, such as changes in diffraction peak shapes. It is anticipated that this technique will provide just-in-time actionable information to drive smarter experiments that effectively deploy multi-modal X-ray diffraction methods spanning many decades of length scales.

A new study shows that graphene sheets can block the signals mosquitoes use to identify a blood meal, potentially enabling a new chemical-free approach to mosquito bite prevention. Researchers showed that multilayer graphene can provide a twofold defense against mosquito bites. The ultra-thin yet strong material acts as a barrier that mosquitoes are unable to bite through. At the same time, experiments showed that graphene also blocks chemical signals mosquitoes use to sense that a blood meal is near, blunting their urge to bite in the first place. The findings suggest that clothing with a graphene lining could be an effective mosquito barrier.

A majority of Americans believes ensuring access to voting is more important than rooting out fraud, the latest NPR/PBS NewsHour/Marist survey finds.

At the same time, there was broad agreement that people should have to show identification when they go to the polls.

Two-thirds of Americans also believe democracy is "under threat," but likely for very different reasons.

"For Democrats, Jan. 6 undoubtedly looms large," said Lee Miringoff, director of the Marist Institute for Public Opinion, referring to the violence and insurrection at the Capitol, "while, for Republicans, it's more likely about Trump and his claims of a rigged election."

Voting access vs. fraud

By a 56%-41% margin, survey respondents said making sure that everyone who wants to vote can do so is a bigger concern than making sure that no one who is ineligible votes.

But there were wide differences by political party and by race.

Among Democrats, almost 9 in 10 said access was more important, but almost three-quarters of Republicans said it was making sure no one votes who isn't eligible.

By race, a slim majority of whites said ensuring everyone who wants to vote can was most important, but almost two-thirds of nonwhites said so.

Photo ID is popular

Nearly 8 in 10 Americans said they believe voters should be required to show government-issued photo identification whenever they vote.

Majorities of Democrats, Republicans, independents, whites and nonwhites all said so. Democrats were far lower, though, with 57% believing photo ID should be required.

Biden holding steady

President Biden gets a 50% job approval rating, largely unchanged from last month. There is a sharp partisan divide with 9 in 10 Democrats approving, and more than 8 in 10 Republicans disapproving.

Biden continues to get his highest ratings when it comes to his handling of the coronavirus pandemic, and his economic approval is holding steady. But Americans have less confidence in his handling of foreign policy, especially immigration. His approval on immigration ticked up slightly from March when it was last measured in the poll.

By a 50%-43% margin, respondents said Biden had strengthened America's role on the world stage.

Americans are split about whether the country is headed in the right direction or not — 49% said it wasn't, 47% said it was. It's an improvement, however, from right after the Jan. 6 insurrection when three-quarters said the country was on the wrong track.

The tone has gotten worse in Washington since Biden was elected, 41% said, but that's better than the two-thirds who said so consistently during the Trump years.

Methodology: The poll of 1,115 U.S. adults was conducted using live telephone interviewers from June 22-29. 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.

The pandemic has once again felled Burning Man. Some burners still plan to gather for informal events on the dusty Black Rock Desert Playa this summer.; Credit: Bernard Friel/Education Images/Universal Images Group via Getty Images

And so it goes: Burning Man 2021 is canceled. It's the second year in a row, the popular arts festival won't be held in Nevada's Black Rock Desert due to the pandemic.

"We have decided to set our sights on Black Rock City 2022," event officials announced in a blog post on Tuesday. In a frequently-asked-questions section, organizers added: "We've heard from many who don't feel ready to come to Black Rock City. While we're confident in our ability to get a permit and to safeguard public health, we know that co-creating Black Rock City in 2021 would put tremendous strain on our community while we are still ironing out uncertainty."

Many would-be attendees praised the decision in comments on the Burning Man website and on social media as a safe one; others are anxiously anticipating a bigger and better 2022 Burn.

But the cancellation has put many people in the event's host community at ease.

Wary of a trend of rising coronavirus cases in some parts of the region, Washoe County's district health officer Kevin Dick said "the right call was made," in order to lower the risk of spreading infection.

"The event draws thousands of people from all over the world," Dick said in an email. "We are seeing large outbreaks of COVID-19 occurring in a number of countries, areas where very contagious COVID-19 variants of concern are prevalent and where low rates of vaccination are occurring."

The head of a local Paiute tribe is also feeling less burdened knowing there won't be the annual pilgrimage. The main highway to get to the Black Rock Desert playa, which normally draws tens of thousands of people to the summer event, cuts through tribal lands.

"For us it is a sigh of relief," said Janet Davis, chairwoman of the Pyramid Lake Paiute Tribe.

Although the event — which brings in about $63 million to the state annually — gives the tribal community a welcome financial boost, Davis said.

"We don't know who's vaccinated and who's not," she said. "We've been trying to keep our reservation safe and that happening was too soon for us to open."

As with last year, the organization will offer virtual programming during Burn Week, from Aug. 29 through Sept. 7, an experience they say drew 165,000 participants in 2020.

In response to a request for more details on the reasons for the cancellation, Burning Man organizers declined to comment further. Earlier this month, though, CEO Marian Goodell said the organization was "weighing the gravity" of implementing a vaccination requirement that she said challenged "radical inclusion," one of the group's 10 principles.

Still, for many burners, the news won't extinguish their plans to trek to the desert in droves. Just like last year, revelers are preparing to hold unofficial gatherings on public land in place of the annual event.

Last summer, those events — the so-called "rogue" and "free" burns or, unmistakably, "Not Burning Man" — drew an estimated 3,000 people to Black Rock Desert during the time Burning Man is normally held, according to the Bureau of Land Management, the federal agency that approves the organization's permits each year.

Kevin Jervis, one such attendee who now lives in Gerlach — a tiny desert town near the event site — welcomed this year's cancellation.

He called it "more of a relief than anything. ... A lot of us liked it better the way it happened last year."

During the informal festivities, Jervis spent a few days between the playa and its outskirts. He said he and his fellow burners felt like it represented the festival's freewheeling roots.

"I've had friends that have been going since '94 and they said it was a lot more like it used to be. We didn't have to go by regulations," he said. "We could have guns, dogs ... it was a lot freer."

Even before the pandemic, burners increasingly saw an annual gathering under siege.

Event-goers who adhere to Burning Man's counterculture beginnings say the festival's explosion in popularity in the past decade has welcomed a host of bad actors who trash the desert and surrounding communities and disregard the event's founding principles, including "decommodification" and the eco-friendly philosophy of "leave no trace."

Some of those perceived threats come from festival officials themselves, he said. A ticket to the main event alone cost over $400 in 2019 — a financial hurdle critics say goes against another tenet long espoused, that "everyone is invited."

"People that have never been before came out last year because they either couldn't get a ticket other years or they were just kind of curious. Or they didn't have the money to go to the actual Burn," said Jervis.

As for the Pyramid Lake Paiute community, with the reservation largely closed during that period last year, Davis said, "we really didn't see the impact" from a public health standpoint.

"You're not talking about 65 — 75,000 people." While there was more traffic, she said, "they moseyed on through and moseyed on out."

In the years leading up to the pandemic, BLM had been cracking down on the event's growth. Were the festival to return this year, Burning Man organizers said they would have had to meet a population cap of 69,000, down from its 80,000 limit for previous events.

Jervis says he won't miss what he describes as organizers' leniency toward "elites" who set up VIP areas at their camps and hire out to construct their art creations instead of making their own.

"A lot of people have gotten sick of what Burning Man's kind of become," he said.

Even if this year was a go, he said, burners would still be setting up their own Burning Man-adjacent happenings.

Following the announcement of the event's cancellation, people are taking to Facebook groups to reminisce about last year's unsanctioned burns and discuss preparations for their own this summer.

"So it seems that as of today there isn't going to be an official [Burning Man Ceremony] this year," James Zapata wrote. "So who's joining me in the dust?"
