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...
Researchers have discovered the charred remains of a flatbread that hunter-gatherers baked 14,400 years ago. It is the oldest direct evidence of bread found to date, predating the advent of agriculture by at least 4,000 years. The findings suggest that...
Researchers have detected Salmonella Paratyphi C, which causes enteric fever, in a 800-year-old human skeleton from Trondheim, Norway. This suggests the potentially lethal disease, more common in hot countries, was present in medieval Europe. Now scientists are speculating that the...
