A new study investigated the mortality and mental health correlates of the iconic Bulletin of the Atomic Scientists' Doomsday Clock.
US bird populations continue alarming decline
The 2025 U. S. State of the Birds Report, produced by a coalition of leading science and conservation organizations, reveals continued widespread declines in American bird populations across all mainland and marine habitats, with 229 species requiring urgent conservation action.
Blind to the burn: Misconceptions about skin cancer risk in the US
Experiencing five or more severe sunburns between the ages of 15 and 20 increases the risk of melanoma by 80% and nonmelanoma skin cancer by 68%. This study is among the few to examine the relationship between perceived cancer risk, concern about being diagnosed, confidence in health, sunburn history, and...
No need to wing it: Bat activity in winter analyzed
Winter in the South can bring about a sharp change in conditions that impact forests and their many inhabitants. However, new research finds that, despite these seasonal shifts, forest management efforts are supporting healthy bat populations.
Mosquito pain receptors are less sensitive during extreme heat
Hotter temperatures may render natural insect repellents less effective against mosquitoes, according to a new study.
Cells ‘speed date’ to find their neighbors when forming tissues
In developing hearts, cells shuffle around, bumping into each other to find their place, and the stakes are high: pairing with the wrong cell could mean the difference between a beating heart and one that falters. A study demonstrates how heart cells go about this 'matchmaking' process. The researchers model...
Gene related to human kidney disease linked to touch in sea anemones
A new article expands our understanding of sensory neurons in the tentacles of sea anemones, linking them to kidney disease in humans through a common gene.
Cities that conducted greenhouse gas emissions inventories moved needle toward reduction
Researchers gathered emissions data from hundreds of US cities that either conducted a greenhouse gas emissions inventory, or reported they employed sustainability staff. The cities that conducted an inventory showed a statistically significant reduction in emissions between 2010 and 2015, while those with sustainability staff did not. Little research had...
Scientists create a type of catalog, the ‘colocatome,’ of non-cancerous cells’ influence on cancer
Scientists are using artificial intelligence to better capture how healthy cells surrounding tumors influence cancer cell behavior and how those interactions can inform treatments.
Medical infusion bags can release microplastics
Microplastics have been found almost everywhere that scientists have looked for them. Now these bits of plastic -- from 1 to 62 micrometers long -- have been found in the filtered solutions used for medical intravenous (IV) infusions. The researchers estimate that thousands of plastic particles could be delivered directly...
