Translesion synthesis polymerases (TLSPs) are non-essential error-prone enzymes that ensure cell survival by facilitating DNA replication in the presence of DNA damage. In addition to their role in bypassing lesions, TLSPs have been implicated in meiotic double strand break repair in several systems. Here we examine the joint contribution of four TLS polymerases to meiotic progression in the fission yeast S. pombe. We observed the dramatic loss of spore viability in fission yeast lacking all four TLSPs which is accompanied by disruptions in chromosome segregation during meiosis I and II. Rec8 cohesin dynamics are altered in the absence of the TLSPs. These data suggest that the TLSPs contribute to multiple aspects of meiotic chromosome dynamics.

The Hope Diamond’s red glow has long been considered a unique property of that stone. Most blue diamonds produce a bluish-white phosphorescence if exposed to ultraviolet light. The few other diamonds known to emit red phosphorescence were commonly assumed to have been from the even larger original stone from which the Hope was cut.

The development of antiviral strategies requires a clear understanding of the principles that control the protein arrangements in viral shells. Considered here are those capsids that violate the paradigmatic Caspar and Klug (CK) model, and it is shown that the important structural features of such anomalous shells from the Picobirnaviridae, Flaviviridae and Leviviridae families can be revealed by models in the form of spherical icosahedral packings of equivalent rhombic structural units (SUs). These SUs are composed of protein dimers forming the investigated capsids which, as shown here, are based on the rhombic triacontahedron (RT) geometry. How to modify the original CK approach in order to make it compatible with the considered rhombic tessellations of a sphere is also discussed. Analogies between capsids self-assembled from dimers and trimers are demonstrated. This analysis reveals the principles controlling the localization of receptor proteins (which recognize the host cell) on the capsid surface.

Smokers who are exposed to radon appear to be at even greater risk for lung cancer, because the effects of smoking and radon are more powerful when the two factors are combined, says a new report by a committee of the National Research Council.

Increased research is the key to developing more widely applicable detection systems to find pipe bombs before they explode and to help catch the perpetrators when a bomb has gone off, says a new report from a committee of the National Research Council.

In response to alarming evidence of high rates of depression and suicide among U.S. health care workers, the National Academy of Medicine is launching a wide-ranging “action collaborative” of multiple organizations to promote clinician well-being and resilience.

A new report from the National Academies of Sciences, Engineering, and Medicine offers detailed recommendations to guide federal statistical agencies in creating a new entity that would enable them to combine data from multiple sources in order to provide more relevant, timely, and detailed statistics – for example, on the unemployment rate or the rate of violent crime.

The global production, trade and use of goods and services has a significant impact on the environment — and rates of consumption are rising. A new study combines two assessment methods to quantify the impact of European trade on the environment. It finds that, overall, the EU was a net importer of environmental impact from 2000 to 2010, that machinery, equipment and vehicles contributed most to the EU’s export impacts and that the EU’s trade balance (import impact minus export impact) is increasing over time. The two assessment methods complement one another well and could form the basis for future country or region-wide studies, suggest the researchers, by enabling a detailed analysis of individual steps within a product’s trade flow, while also providing a larger picture of the overall process.

As the development of nanomaterials increases, a recent study recommends combining life cycle analysis and risk assessment to improve our understanding of the potential environmental and human health impacts of products containing nanomaterials.

New research has recommended using both ecological and carbon footprints to assess the impact of environmental policies and strategies at a regional level. The combination can provide an evidence-based means of evaluating policies to help achieve environmental targets.

Higher public awareness of sustainable fishing practices, led by environmental NGOs, may have helped reduce the incidence of mislabelled fish in the UK, compared to Ireland, according to a recent study which assessed levels of fish fraudulently sold as ‘cod’ in these two countries.

A set of guidelines has been developed to reduce soil erosion by planting vegetation in desertification hotspots.Farmers and policymakers can use the guidelines to identify the most suitable places to plant vegetation in the channels where water and sediment move through the landscape.

A global cropland percentage map and a global field size map have been created for the first time to guide scientists and policymakers interested in global agricultural modelling and assessment. Both maps are for the baseline year 2005 and combined multiple data sets from global, regional and national levels to achieve a high level of accuracy and 1 km2 resolution.

Outside the laboratory, living organisms are never subject to single stressors at set doses. In the real world, they face an intricate array of physical, chemical and biological environmental stressors that vary in space and time. The problem of assessing these complex risks for human health and the environment is a great challenge for scientists and regulators alike. For example, even if Maximum Permissible Concentrations (MPCs) for individual contaminants are not exceeded in water, in combination they can still be potentially hazardous to wildlife. This thematic issue reports on scientific research which can help us overcome some of the challenges associated with assessing the combination effects of chemicals.

New research in Spain has explored solutions to reducing traffic noise, and suggests that the best option is to combine global measures, such as speed restrictions, and local measures, such as noise screens.

A new study has assessed the annoyance caused by a combination of noises typically found on an industrial site. The results could help improve total noise annoyance prediction models. For example, it was found that ‘broadband’ noises, which consist of a wide range of frequencies, lead to more annoyance if they are combined with a specific additional set of low frequency noises, which can lead to an overall identical noise level.

Assessment (ERA), each with different goals. The researchers find that overlaps between the three assessments could be combined to create a more comprehensive form of ERA, usable by regulators and environmental decision makers.

Annual maps of forest cover in Indonesia reveal that, between 2000 and 2008, almost 10 per cent of forest cover on the islands was lost. Around one fifth of this loss occurred in regions where logging is restricted or prohibited. The new maps will help Indonesia meet the objectives of the UN REDD+ programme, which aims to reduce deforestation and forest degradation.

New research in Australia has investigated the impact of labelling groceries with their level of CO2 emissions. A convenience store that introduced these labels found that the share of green (low CO2 emissions) purchases increased by 5 per cent. If these products were also low priced, the share of green purchases from the store increased by 20 per cent.

Administrative sanctions against environmental crime, such as fines, are generally easier and cheaper to implement than criminal punishment methods, such as prison sentences. This study explored enforcement methods for environmental crime in four Western European areas: Flanders (Belgium), Germany, the Netherlands and the UK. Based on their findings, the authors say it is most cost-effective — and may increase deterrence — to use both forms of enforcement.

Water shortages are an urgent issue in many areas of the world and it is likely that the construction of desalination plants will increase to meet the rising demand for fresh water. A new study has evaluated a combined process to manage both the brine by-product from desalination plants and capture carbon dioxide.

Pioneering methods used in the Netherlands combine remediation of brownfield sites with the use of groundwater for heat cold storage (HCS, or ATES: Aquifer Thermal Energy Storage) to achieve both low-cost remediation and sustainable use of energy.

Domestic water saving is important — not only to address water scarcity and drought, but also to save energy and tackle climate change. Water-management strategies are needed to prevent these shortages, and include incentives to change consumers’ behaviour concerning water use. This study examines the design of a behaviour-change system and a linked incentive model to stimulate a sustainable change in water-consumption behaviour.

The new features will allow admins to disable the use of a Personal Meeting ID (PMI) for scheduling or starting an instant meeting. As per the company, disabling the use of PMIs reduces that risk altogether and doesn’t leave PMI security up to individual users.

A new study has combined two research methods to assess the risk of pesticide contamination within a river basin and identify locations of risk. Six groups of pesticides were identified in a French river basin and one specific area was labelled as 'high risk' due to intense agriculture.

Surface water is considered to be of good ecological quality if the Maximum Permissible Concentrations (MPCs) of contaminants in the water are not exceeded. However, new research suggests that even when each individual contaminant does not exceed its MPC, water quality may be compromised by the combined effects of contaminants.

How does the law protect the environment? The responsibility for the legal protection of the environment rests largely with public authorities such as the police, local authorities or specialised regulatory agencies. However, more recently, attention has been focused on the enforcement of environmental law — how it should most effectively be implemented, how best to ensure compliance, and how best to deal with breaches of environmental law where they occur. This Thematic Issue presents recent research into the value of emerging networks of enforcement bodies, the need to exploit new technologies and strategies, the use of appropriate sanctions and the added value of a compliance assurance conceptual framework.
