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.

Researchers have used a unique microscopic technique to examine the dynamics of pollen tubes in the Arabidopsis plant. They were able to observe the mechanism of one-to-one pollen tube guidance, a process that ensures successful pollination of plants. This process is influenced by multi-step repelling and attracting signals. The results are important for the cultivation of crops, especially under unfavorable environmental conditions.

In human populations, it is relatively easy to calculate demographic trends and make projections of the future if data on basic processes such as births and immigration is known. The data, given by individuals, can be also death and emigration, which subtract. In the wild, on the other hand, understanding the processes that determine wildlife demographic patterns is a highly complex challenge for the scientific community. Although a wide range of methods are now available to estimate births and deaths in wildlife, quantifying emigration and immigration has historically been difficult or impossible in many populations of interest, particularly in the case of threatened species.

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.

A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.

The release of captive bred animals carefully selected for their genes can make a significant contribution to the successful recovery of the dwindling wild population and avert the prospect of extinction. Despite revealing extremely low levels of genetic diversity in the wild leopard population in Oman, the research team discovered higher levels of genetic diversity in captive leopards across the region. This important genetic resource has the potential for a major role in successful recovery of the Arabian leopard.

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.

Extreme heat events were associated with increased asthma hospital visits, according to new research.

The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the Brazilian merganser.

A team delves into the spatiotemporal patterns of water volume and total organic carbon concentration of agricultural reservoirs.

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.

A new study reports that the U.S. Drought Monitor's weekly maps of nationwide drought conditions -- which help direct emergency federal aid -- have captured the steady march of climate change, but the Drought Monitor has itself failed to adapt to that reality. Areas of the country are spending more and more time in severe drought conditions the Drought Monitor still considers to be rare occurrences. The consequences could be that swaths of the country -- particularly in the West -- may not receive aid in keeping with the enhanced risk of drought as periodic emergencies become persistent new realities.

Scientists have found that the record-low levels of sea ice around Antarctica in 2023 were extremely unlikely to happen without the influence of climate change. This low was a one-in-a-2000-year event without climate change and four times more likely under its effects.
