Extreme heat and extreme cold are both associated with increased risks of death from ischemic and hemorrhagic stroke, according to a new study. The researchers found that the link between extreme temperatures and stroke mortality was stronger in low-income countries than in high-income countries.

In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials.

Maize can grow successfully in very different local conditions. An international study has now demonstrated the important role of the plant root system. The researchers analyzed more than 9,000 varieties in the study and were able to show that their roots varied considerably -- depending on how dry the location is where each variety was cultivated. They were also able to identify an important gene that plays a role in the plant's ability to adapt. This gene could be the key to developing varieties of maize that cope better with climate change.

Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.

A new study has found that residents living in the downstream communities that border the Merrimack River are at a substantially increased risk of developing acute gastrointestinal illnesses (AGI) in the four days following large-volume combined sewer overflows (CSOs).

To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay.

Scientists report a family of tin-based catalysts that efficiently converts CO2 into ethanol, acetic acid and formic acid. These liquid hydrocarbons are among the most produced chemicals in the U.S and are found in many commercial products.

Urban greening projects should consider historical development patterns and past discriminatory practices to avoid exacerbating the unequal distribution of environmental benefits, says an urban and regional planning professor.

Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.

Replacing diesel school buses with electric school buses may yield up to $247,600 in climate and health benefits per individual bus, according to a new study. The researchers found that these benefits -- including fewer greenhouse gas emissions and reduced rates of adult mortality and childhood asthma -- and their associated savings are strongest in large cities and among fleets of old (2005 and before) buses.

Glaciologists show evidence of warm ocean water intruding kilometers beneath grounded ice at Thwaites Glacier in West Antarctica. The findings suggest that existing climate models are underestimating the impact of ocean and ice interactions in future sea level rise projections.

A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.

Findings indicate that soil stored under refrigerated or air-dried conditions can still retain the needed information for understanding microbial community composition and structure for many years.

Researchers have conducted a worldwide analysis of voluntary carbon offset programs and identified trends into which types of carbon reduction technologies are selected and prioritized. Their findings provide important insights for policymakers to improve the effectiveness and credibility of the carbon offset market.
