Being able to visualize biology at the molecular level is essential for our understanding of the world. A structural biology approach reveals the molecular basis of disease processes and can guide the design of new drugs as well as aid in the optimization of existing medicines. However, due to the lack of a synchrotron light source, adequate infrastructure, skilled persons and incentives for scientists in addition to limited financial support, the majority of countries across the African continent do not conduct structural biology research. Nevertheless, with technological advances such as robotic protein crystallization and remote data collection capabilities offered by many synchrotron light sources, X-ray crystallography is now potentially accessible to Africa-based scientists. This leap in technology led to the establishment in 2017 of BioStruct-Africa, a non-profit organization (Swedish corporate ID: 802509-6689) whose core aim is capacity building for African students and researchers in the field of structural biology with a focus on prevalent diseases in the African continent. The team is mainly composed of, but not limited to, a group of structural biologists from the African diaspora. The members of BioStruct-Africa have taken up the mantle to serve as a catalyst in order to facilitate the information and technology transfer to those with the greatest desire and need within Africa. BioStruct-Africa achieves this by organizing workshops onsite at our partner universities and institutions based in Africa, followed by post-hoc online mentoring of participants to ensure sustainable capacity building. The workshops provide a theoretical background on protein crystallography, hands-on practical experience in protein crystallization, crystal harvesting and cryo-cooling, live remote data collection on a synchrotron beamline, but most importantly the links to drive further collaboration through research. Capacity building for Africa-based researchers in structural biology is crucial to win the fight against the neglected tropical diseases, e.g. ascariasis, hookworm, trichuriasis, lymphatic filariasis, active trachoma, loiasis, yellow fever, leprosy, rabies, sleeping sickness, onchocerciasis, schistosomiasis, etc., that constitute significant health, social and economic burdens to the continent. BioStruct-Africa aims to build local and national expertise that will have direct benefits for healthcare within the continent.

X-ray absorption linear dichroism of rutile TiO2 at the Ti K-edge provides information about the electronic states involved in the pre-edge transitions. Here, linear dichroism with high energy resolution is analyzed in combination with ab initio finite difference method calculations and spherical tensor analysis. It provides an assignment of the three pre-edge peaks beyond the octahedral crystal field splitting approximation and estimates the spatial extension of the corresponding final states. It is then discussed for the first time the X-ray absorption (XAS) of pentacoordinated titanium atoms due to oxygen vacancies and it is found that, similarly to anatase TiO2, rutile is expected to exhibit a transition on the low-energy side of peak A3. Its apparent absence in the experiment is related to the degree of p–d orbital mixing which is small in rutile due to its centrosymmetric point group. A recent XAS linear dichroism study on anatase TiO2 single crystals has shown that peak A2 has an intrinsic origin and is due to a quadrupolar transition to the 3d energy levels. In rutile, due to its centrosymmetric point group, the corresponding peak A2 has a small dipole moment explaining the weak transition. The results are confronted with recent picosecond X-ray absorption spectroscopy on rutile TiO2 nanoparticles.

The isostructural title compounds, poly[piperazin-1-ium [di-μ-bromido-caesium]], {(C4H11N2)[CsBr2]}n, and poly[piperazin-1-ium [di-μ-bromido-rubidium]], {(C4H11N2)[RbBr2]}n, contain singly-protonated piperazin-1-ium cations and unusual ABr6 (A = Cs or Rb) trigonal prisms. The prisms are linked into a distinctive `curtain wall' arrangement propagating in the (010) plane by face and edge sharing. In each case, a network of N—H⋯N, N—H⋯Br and N—H⋯(Br,Br) hydrogen bonds consolidates the structure.

The title hydrated mol­ecular salt (systematic name: tetra-n-butyl­ammonium 2,6-dioxo-1,2,3,6-tetra­hydro­pyrimidine-4-carboxyl­ate monohydrate), C16H36N+·C5H3N2O4−·H2O, crystallizes with N—H⋯O and O—H⋯O hydrogen-bonded double-stranded anti­parallel ribbons consisting of the hydro­philic orotate monoanions and water mol­ecules, separated by the bulky hydro­phobic cations. The hydro­phobic and hydro­philic regions of the structure are joined by weaker non-classical C—H⋯O hydrogen bonds. An accurate structure analysis conducted at T = 100 K is compared to a lower-resolution less accurate determination using data measured at T = 295 K. The results of both analyses are evaluated using a knowledge-based approach, and it is found that the less accurate room-temperature structure analysis provides geometric data that are similar to those derived from the accurate low-temperature analysis, with both sets of results consistent with previously analyzed structures. A minor disorder of one methyl group in the cation at low temperature was found to be slightly more complex at room temperature; while still involving a minor fraction of the structure, the disorder at room temperature was found to require a non-routine treatment, which is described in detail.

Washing your car with a garden hose can use up to 120 gallons of water. Most corner conveyor belt operations use less, but all that water can add up, as we told you in August.

That’s why the group LA Waterkeeper is challenging motorists to drive dirty and pledge to skip car washes for 60 days. 

"Water conservation is the easiest and most affordable way to quickly reduce water demand and also extend supplies into next year," says Liz Crosson, the group's executive director. 

This summer Ventura County’s water agency asked people to skip washing their rides for a month; some people got detailing and car washes as a reward. Crosson’s group is hoping bragging rights will be enough of an incentive. (Though there are some as-yet-undisclosed prizes.)

People who live in LA are really excited and interested by the cars that they drive," Crosson says. "And frankly, you can have a dirty car and you can have a sticker and have an excuse for having a dirty car so it saves your image too."

The campaign’s just kicking off this weekend (at the Abbott-Kinney festival), but Crosson’s already optimistic for success. Early adopters of the pledge are hundreds of people from the online site Reddit and the general manager for the Los Angeles Department of Water and Power.

The Supreme Court's second day of arguments by phone was devoted to a new version of a case it decided seven years ago involving federal money to fight AIDS around the world.; Credit: Andrew Harnik/AP

The Supreme Court kicked off a second day of telephone arguments Tuesday with a case that mingles sex, the HIV/AIDS epidemic and free speech.

At issue is whether the government can require private nonprofits to denounce prostitution in order to qualify for U.S foreign aid grants aimed at fighting the worldwide AIDS epidemic. This is the second time the court has faced this issue, but this time it comes with a twist.

In 2003, Congress, at the urging of President George W. Bush, enacted a major foreign aid program to fight the HIV/AIDS pandemic and prevent new infections worldwide. In appropriating the money, Congress included a provision requiring any private organization that received funding through the program to adopt an explicit policy denouncing prostitution and sex trafficking.

In 2013, the Supreme Court struck down that provision, declaring it unconstitutional because it compelled U.S. nonprofits to adopt an explicit policy as a condition for receiving grant money. By a 6-2 vote, the high court said such a requirement interfered with the free speech rights of private U.S. organizations engaged in the fight against AIDS.

The case was back Tuesday, but this time, the question was whether foreign organizations closely affiliated with those same U.S. nonprofits can be required to adopt the policy denouncing prostitution.

Defending the provision was Assistant to the Solicitor General Christopher Michel. He argued that foreign affiliates of U.S. organizations like Save The Children, CARE and WorldVision are separate legal entities from their parent U.S. organizations, and that as foreign entities, they have no rights under the U.S. Constitution.

Chief Justice John Roberts, who wrote the 2013 decision, seemed unpersuaded.

"Is it reasonable to insist on formal corporate ties in this context?" he asked. "It's undisputed that to be effective in many of the foreign countries involved here, you have to operate through a foreign entity."

Michel responded that if the U.S. nonprofits "make the choice to operate through a foreign entity because they decide that is more convenient or more effective, they have to accept the bitter with the sweet."

Roberts still seemed doubtful, noting that the U.S. nonprofits and their foreign affiliates "have the same name, the same logo, the same brand. And I wonder if it makes more sense to think of the foreign entity as simply another channel for the domestic entity's speech."

Representing the nonprofits was lawyer David Bowker. He maintained that for all practical purposes, there is no difference between the U.S. nonprofits and their foreign affiliates, so making the affiliate adopt an anti-prostitution message effectively puts words in the mouth of the U.S. nonprofit.

Questioned by Justice Clarence Thomas, Bowker said that the harm suffered by the U.S. nongovernmental organizations is that their foreign affiliates must either lose their funding by refusing to comply with the anti-prostitution policy or undermine their mission by denouncing the very people they need to work with — namely prostitutes. And if the foreign affiliates make the pledge needed to get funding, he said, the U.S. parent organizations have to disavow their own affiliates' anti-prostitution pledge, thus harming the entire anti-AIDS fight.

"It's a Catch-22 for these U.S. organizations," said Bowker.

Justice Stephen Breyer followed up: "So why don't you simply write a grant to get all the money yourself and then you give it to CARE India? Why doesn't that work?"

Because, replied Bowker, under the statute, CARE USA, in subcontracting a grant to CARE India, would be required to impose the anti-prostitution pledge on its own affiliate on behalf of the government.

Justice Samuel Alito, who signed on to the court's 2013 decision, said he had more concerns in this case — mainly "that it will force Congress to either withhold foreign aid entirely or allow foreign aid to be used in ways that are contrary to the interests of the people of this country."

Justice Brett Kavanaugh followed up: "Suppose the U.S. government wants to fund foreign NGOs that support peace in the Middle East but only if the NGOs explicitly recognize Israel as a legitimate state. Are you saying the U.S. can't impose that kind of speech restriction on foreign NGOs that are affiliated with U.S. organizations?"

Bowker said that kind of a restriction would likely be acceptable because the aid in that case would be tied to the U.S. relationship with Israel.

Kavanaugh moved on to another question, noting, "The government says your position would unleash foreign affiliates of U.S. corporations to pump money" into U.S. election campaigns, something that is explicitly barred under current law.

Bowker replied that U.S. campaign laws, as ruled on by the Supreme Court in prior cases, allow the ban on foreign contributions because they do not come from U.S. entities at all.

A decision in the case is expected some time this summer. While the court usually concludes its work by the end of June, it is expected that this term will extend into July because the arguments in this and nine other cases were postponed for more than a month because of the coronavirus.

Effective ‘knowledge exchange’ - the process of producing, sharing, understanding and using knowledge - is vital to good environmental management. New research has uncovered five principles for this process which could help researchers, decision makers and other parties work together to better manage environmental change.

A research update on climate change has indicated that many global risks are now assessed as stronger than predicted by the 2007 IPCC Fourth Assessment Report (AR4). The risk of large sea-level rise, extreme weather events and ocean acidification are all thought to be underestimated by the AR4.

Ever since the 1950s discovery of the solar wind - the constant flow of charged particles from the sun - there's been a stark disconnect between this outpouring and the sun itself. As it approaches Earth, the solar wind is gusty and turbulent. But near the sun where it originates, this wind is structured in distinct rays, much like a child's simple drawing of the sun. The details of the transition from defined rays in the corona, the sun's upper atmosphere, to the solar wind have been, until now, a mystery.

The only way to establish a long-lasting and effective strategy for forest management is through collaboration between ‘conventional’ scientists and local experts, according to new research.

Understanding the social context of Swedish forestry is key to understanding how the sector could be persuaded to move beyond ‘business-as-usual’ practices, to prepare for future climate risks, argues a new study. Using an approach that provides insights for future behavioural change more widely, the researchers explore the influences on forest managers’ behaviour, and highlight certification schemes as one important driver of actions which make forests better adapted to climate change. Knowledge on climate change risks and actions in itself is not enough to change behaviour, the study finds. For many environmentalists it may seem ‘logical’ for forestry to adapt now to future climate change: it epitomises an industry where actions taken today will determine long-term development, given that trees will not be harvested until 70–90 years after planting. However, the sector has taken limited actions to adapt, despite an abundance of available information on the impacts of climate change — such as storms, drought and changes in insect population.

Outputs of conservation planning research are likely to be translated into action more quickly and successfully if a transdisciplinary approach is adopted, according to a recent study. The researchers have applied a transdisciplinary framework 'pyramid of knowledge' to aid in understanding the process of converting research into action, which may also be applicable to other academic disciplines.

Agricultural land use presents a number of environmental challenges, which the European Commission is committed to addressing through a range of agri-environmental policies. A new study points to the importance of aligning agri-environmental policies with farmers’ needs and operations. Using the case of land clearing in Finland, the research underlines the importance of incorporating input from grassroots stakeholders into policy design.

Research assessments should focus more on engagement processes and less on impacts and outcomes, a new study suggests. The authors examined researchers’ intended impacts and motivational factors, and stated that a change in research evaluation methods, together with better direction from university managers, could help incentivise knowledge exchange and engagement between departments and non-academic entities.

AI-based recognition systems, and smart security video networks have led to a paradigm shift in the architecture of security video systems.

While the cloud was seen as a good technology to adopt until some time ago, it has now become a must in order to navigate through these challenging times. Companies that are 100 percent on the cloud have been able to transition far more rapidly than others, making them more agile than their peers.

While workloads are increasingly moving from traditional to cloud data centers - both private and public, hybridization has allowed mission-critical workloads to stay on-premise. Multi-cloud adoption is also being driven by the evolution of new orchestration and management services that are helping to define and run cloud processes and create competitive solutions.

While Edge data centers will be providing an array of services independently, a more centralized data center can be backing them up with cloud services and analytics.

A recent analysis highlights the difference between the academic concept and the practical concept of ecosystem services. It suggests that academic science aims to discover and apply general and timeless concepts to measure ecosystem services, whereas in practice, stakeholders' valuations of ecosystem services vary with place and time.

New research has explored how well different governance systems can achieve desirable conservation outcomes. Results confirmed the importance of adaptive management, which relies on regular monitoring to enable 'learning through doing' to refine actions, and suggested that leadership using expert knowledge was also significant in successful governance.

Depositing dredged material on the seabed can significantly reduce the functioning of marine habitats, diminishing the amount of food available for fish and other animals further up the food chain, new research suggests. The author of the study calls for inclusion of this effect into environmental impact assessments of dredging.

Hedgerows are vital habitats in intensively managed landscapes, providing food and shelter for wildlife. How hedgerows are managed affects their structure, with dense, woody hedges being the most valuable for conservation. A recent study has found an alternative method of hedging that is cheaper than traditional hedge laying but offers the same benefits of dense new growth and berry provision for wildlife. Use of this method could double the length of hedgerows being rejuvenated in England, the authors estimate.
