A new study suggests that two sets of dynamics initiate and perpetuate the kinds of leaps of faith firefighters and others in high-risk occupations routinely take: supporting and sustaining. The findings convey what goes into a person’s ability to make critical...
Homo sapiens were able to thrive because they could generalize across different kinds of environments, but then also rapidly specialize upon encountering specifically challenging environments, say researchers. They call this new ecological role the “general specialist.” The Homo sapiens that migrated...
A new predictive model that examines spore-forming bacteria and when they’ll emerge may make the “sell-by” and “best-by” dates on milk cartons more meaningful and accurate, according to research. “Putting dates on milk cartons is a big issue, because consumers...
Astronomy students sorted through 101 clouds of gas to find those that may be in the first phases of forming massive stars. “There’s still a pretty open question in astronomy when it comes to massive star formation,” says Jenny Calahan,...
Scientists have deduced that the Andromeda galaxy, our closest large galactic neighbor, shredded and cannibalized a massive galaxy two billion years ago. Even though it was mostly shredded, this massive galaxy left behind a rich trail of evidence: an almost...
Observations made with ESO’s Very Large Telescope have for the first time revealed the effects predicted by Einstein’s general relativity on the motion of a star passing through the extreme gravitational field near the supermassive black hole in the...
Biologists warn that federal plans to build a wall along the US-Mexico border could severely threaten some of the unique species that live there—and even push some to extinction in the US. Borderlands are synonymous with desolation, but the Mexico-US...
Despite overall lower levels of harmful emissions from power plants and vehicles throughout the year, winter air pollution in the Eastern United States remains high. A new study explains why. Summer used to be the poster child for haze-containing particles...
Dogs not only go out of their way to comfort their upset owner, but will overcome obstacles to do it quickly, experiments show. In the journal Learning & Behavior, researchers show that dogs with strong bonds to their owners hurried...
Projected temperature increases through 2050 could lead to an additional 21,000 suicides in the United States and Mexico, new research finds. By comparing historical temperature and suicide data, researchers found a strong correlation between warm weather and increased suicides. They...
