New research shows that pathogens that incubate at higher temperatures are more infectious. Yet the computer models that predict the spread of epidemics from climate change—such as crop blights or disease outbreaks—may not be taking into account this important...
Researchers have developed a technique that offers new insight into “cellular memory.” The cells in our body divide constantly throughout life. But how do cells remember whether to develop into a skin, liver, or intestinal cell? It’s a question that...
In the 19th century, the “rain follows the plow” myth was a justification for settling the Great Plains. The cultivation of semi-arid to arid land was said to increase rainfall by moistening the soil and humidifying the atmosphere. Subsequent research...
Even if we achieve the carbon emissions reductions that the Paris Agreement calls for, there is the risk of the planet entering “hothouse Earth” conditions. A “hothouse Earth” climate will in the long term stabilize at a global average of...
Scientists are officially debunking the myth that megalodon sharks still exist. The whale-eating monsters became extinct about 2.6 million years ago. “I was drawn to the study of Carcharocles megalodon’s extinction because it is fundamental to know when species became...
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...
