Many biologists are now routinely seeking to determine the three-dimensional structures of their proteins of choice, illustrating the importance of this knowledge, but also of the simplification and streamlining of structure-determination processes. Despite the fact that most software packages offer simple pipelines, for the non-expert navigating the outputs and understanding the key aspects can be daunting. Here, the structure determination of the type IV pili (TFP) protein PilA1 from Clostridioides difficile is used to illustrate the different steps involved, the key decision criteria and important considerations when using the most common pipelines and software. Molecular-replacement pipelines within CCP4i2 are presented to illustrate the more commonly used processes. Previous knowledge of the biology and structure of TFP pilins, particularly the presence of a long, N-terminal α-helix required for pilus formation, allowed informed decisions to be made during the structure-determination strategy. The PilA1 structure was finally successfully determined using ARCIMBOLDO and the ab initio MR strategy used is described.

It takes a Tlingit artist up to 2,000 hours, or 83 days, to weave just one ceremonial robe. Not surprisingly, this art form is practiced by a dedicated few including Tlingit artists Teri Rofkar and Shelly Laws of Alaska. In their presentation for the Smithsonian Spotlight series hosted by the Arctic Studies Center at the Anchorage Museum, Rofkar and Laws discuss the methods and cultural significance of robes, spruce root baskets and more.

A new report from the National Research Council recommends best practices that law enforcement agencies and courts should follow to improve the likelihood that eyewitness identifications used in criminal cases will be accurate.

A new report from the National Academies of Sciences, Engineering, and Medicine identifies six promising practices to improve health care for individuals with social risk factors for poor health care outcomes, such as people who are in a low socio-economic position, reside in disadvantaged neighborhoods, identify as a racial or ethnic minority, or possess limited health literacy.

Bullying is a serious public health problem, with significant short- and long-term psychological consequences for both the targets and perpetrators of such behavior, and requires a commitment to developing preventive and interventional policies and practices that could make a tangible difference in the lives of many children, says a new report from the National Academies of Sciences, Engineering, and Medicine.

A number of strategies used by the police to proactively prevent crimes have proved to be successful at crime reduction, at least in the short term, and most strategies do not harm communities’ attitudes toward police, finds a new report by the National Academies of Sciences, Engineering, and Medicine.

The changes in brain structure and connectivity that occur between the ages of 10 and 25 present adolescents with unique opportunities for positive, life-shaping development, and for recovering from past adversity, says a new report from the National Academies of Sciences, Engineering, and Medicine.

U.S. colleges and universities should take a more intentional, inclusive, and evidence-based approach to mentoring students in STEMM (science, technology, engineering, mathematics, and medicine) – a shift that could engage and help retain a broader group of students in these fields, says a new report from the National Academies of Sciences, Engineering, and Medicine.

The 1.3 million nursing home residents in the U.S. make up less than 0.5 percent of the nation’s population, but represent approximately 15 percent of COVID-19 related deaths to date.

A new assessment tool has been developed to evaluate the sustainability initiatives of government departments. On its first application, in the UK???s Department of Work and Pensions, it identified a good mix of practice alongside areas for improvement. The authors suggest that this method could be used elsewhere to assess how well an organisation is embedding the principles of sustainable development into all aspects of its business.

Building Information Modelling (BIM) can enhance the design of a building, reduce costs and save energy. However, little research has been carried out on its impact on sustainable practices. A US survey illustrates that many practitioners do not see sustainability as a primary application, suggesting that more effort is needed to encourage the integration of ‘green’ design and construction into BIM.

Phosphorus is a major pollutant of surface waters, contributing to poor water quality. A recent study investigated best management practices to reduce the over-application of phosphorus and minimise phosphorus losses from agriculture in four regions across Europe and North America.

The costs and benefits of sustainable land management have been collated in a new review. Data from a global archive was analysed for the costs of sustainable practices and technologies and for land users’ perceptions of cost–benefit ratios. Most respondents had a positive view of the short-term cost-benefit ratio, and a strongly positive view of the long term. Low upfront costs, long-term planning and security of land tenure were identified as important factors to facilitate these practices.

Risk analysis and technology assessment (RATA) involves assessing the possible human, environmental and societal risks of a novel technology at various stages of the development process. However, best practices for RATA’s successful incorporation into large-scale research programmes are still in development. In a recent study, researchers present a case study of their efforts to bring RATA into practice within a large Dutch nanotechnology consortium. By outlining the procedures and products they developed and reflecting on their experiences, the researchers provide valuable insights for the future integration of RATA in technology development projects. The findings are relevant to stakeholders with an interest in supporting the design of key enabling technologies, including governmental agencies and industrial partners.

Adapting to climate change in coastal cities needs further development of the resilience approach as well as identifying how it can be practically used in local actions, according to a new study. The researchers present resilience as a flexible, practical way of dealing with climate change's impacts, such as coastal flooding, which can be easily built into adaptation measures.

To solve the problem of food waste we need to radically rethink how our food is produced and consumed, researchers argue in a recent study. They propose a new framework that considers how to reduce wastage throughout the supply chain. Preventing excess levels of food production and consumption in the first place is its most important step.

Food packaging waste is currently under scrutiny. In the context of its Circular Economy Action Plan, the EU is addressing this through, among others, its Product Environmental Footprint (PEF) initiative , which aims to enhance the reliability of environmental claims — both in a business-to-consumer and in a business-to-business context. The initiative aims, therefore, to boost the market of green and circular products. However, a review of the methods available for assessing the environmental sustainability of packaging now highlights the difficulty of clearly characterising packaging's environmental impact. The study suggests a new, fully quantifiable framework that could help to standardise assessment methods and bring 'environmental footprint labelling' to fruition.

Many workplaces have developed mobility policies to reduce the number of staff commuting to work using single occupant vehicles (SOVs). A new study from Belgium reveals how companies can influence their employees' choice of transport to work and looks at the best ways to promote alternative means of commuting.

Bats can adapt to certain changes in habitat that threaten their preferred roosting sites. A new study from Poland shows that bats will widen their criteria for selecting roosting sites if forest management practices limit their preferred sites. However, experts recommend that small patches of old growth forest suitable for bat roosting are maintained as the bats in this study did not adapt to young woodland.

Two ‘best practice’ case studies of brownfield regeneration in Germany and the UK have been analysed by researchers. Liverpool's and Cologne's two flagship waterfront developments were chosen in order to provide insights for other redevelopment projects. The assessment demonstrates that, if correctly managed, brownfield sites can help stimulate economic development in poor areas.

Landfill taxes and ‘enhanced waste management’ practices have been introduced to reduce the amount of waste that goes to landfill and to convert waste into useful products. This study investigated the interplay of these two policy options in Belgium, generating findings that could help Europe move towards a resource-efficient, circular economy.

A study into how agriculture can help humanity meet the United Nations’ Sustainable Development Goals finds that research in Europe on agricultural land systems largely omits key priorities from policy and practice. The researchers identify 32 variables that researchers, policymakers and practitioners collectively prioritise when it comes to European agricultural systems, and suggest that future research includes these in order to more comprehensively analyse trade-offs and identify opportunities for sustainable progress.

In the face of substantial evidence that modern land use management practices have increased runoff at the local scale, a new study reveals changes in local land use management practices can reduce the risk of local flooding. However, there is little evidence so far that these local increases in runoff culminate in large-scale flooding effects. To address this lack of evidence, the researchers present a model that maps the downstream rate of flow back to its source areas.

Worsening soil erosion in north-western Europe may be the result of a switch from traditional dairy farming to cash crops. However, even if all dairy farming ceased, reductions in runoff of up to 76% could be achieved if best agricultural practices are employed, at a cost of approximately €45 per hectare for the first three years, new research from the Austreberthe watershed in France suggests.

Soil erosion in Italy could be reduced by 43% if Good Agricultural and Environmental Conditions (GAEC) were fully adopted, a recent study has found. Reducing soil erosion would also increase soil organic carbon stocks, particularly on cultivated sloping land.

Halogenated nitrogenous disinfection by-products (N-DBPs) in water increase bacterial resistance to antibiotics, new research shows. The study found that a strain of bacteria which can cause disease in humans, Pseudomonas aeruginosa, increased its resistance to a range of different antibiotics by an average of 5.5 times after the bacteria were exposed to chemicals which form as by-products of common water treatment procedures. The results highlight the risks to public health which these currently unregulated by-products may cause.

Different management practices using pesticides affect the diversity, number and ecological traits of ground spiders in apple orchards, a new study finds. Because spiders are viewed as good indicators of the quality of an entire ecosystem, the results reveal that organic orchard management may be better for local management and landscape characteristics when compared to those with pesticide use.

Copper (Cu) is frequently used in agricultural practices, particularly in fungicides, used extensively in the management of permanent crops, such as vineyards, olive groves, and fruit orchards — all crops of significant economic importance to the EU. An investigation into the factors influencing Cu distribution in the topsoils of 25 EU Member States has identified that, in conjunction with other factors such as topsoil properties, land cover, and climate, such agricultural management practices play a role in influencing Cu concentration. The analysis used 21 682 soil samples from the EU-funded Land Use and Coverage Area frame Survey (LUCAS)¹ and found that vineyards, olive groves, and orchards had the highest mean soil Cu concentrations of all land use categories. The findings highlight the major impact of land use and agricultural practices on soil Cu concentrations and emphasise a need for more sustainable land management practices.
