Long-term exposure to arsenic in water may increase cardiovascular risk and especially heart disease risk even at exposure levels below the federal regulatory limit, according to new research. A study describes exposure-response relationships at concentrations below the current regulatory limit and substantiates that prolonged exposure to arsenic in water contributes...

A new method that research teams can use to measure and compare different forms of proteins and protein complexes helped reveal a previously unseen molecular signature of how algal genomes are controlled during the cell cycle.

Healthy coral reefs echo with a chorus of grunts and purrs from fish feeding, looking for mates, or defending their territories, underscored by the persistent crackling of snapping shrimp. Larval corals use these sounds as cues to decide where to choose a home. The researchers found that now a second...

Scientists modeled the number of 'outdoor days' -- with comfortable temperatures for outside activities -- that U.S. regions will experience as climate warms. States in the Southeast will lose a significant number of outdoor days, while the Northwest should see a slight increase.

Twenty-two new species of gall wasps have been identified and named, thanks to new research. The study nearly doubles the number of known species in this genus of wasps.

Changing precipitation patterns in the Neotropics, one of Earth's most biodiverse regions, could threaten two-thirds of the area's bird species by the year 2100 if climate change goes unchecked, according to research. This would represent a dramatic loss, as the region is home to 30% of all bird species globally.

Biologists are working to save one of the most endangered white shark populations on the planet. The research team located signs of the remaining white sharks in the Sicilian Channel.

In the race for solutions to unlock untapped sources, engineers have developed new technology enabling direct lithium extraction from extreme environments like the desert.
