It's one of the greatest and longest-running mysteries surrounding, quite literally, our sun -- why is its outer atmosphere hotter than its fiery surface? University of Michigan researchers believe they have the answer, and hope to prove it with...
Human-generated greenhouse gases and atmospheric particles were affecting global drought risk as far back as the early 20th century, according to a study from NASA's Goddard Institute for Space Studies (GISS) in New York City. The study, published in...
Evolution is a rich and dynamic process. Species respond to pressures in a variety of ways, most of which reduce to finding food, avoiding becoming someone else's food and attracting a mate. To solve that last one the...
Researchers have discovered a gene that drives color differences within a species of bumble bees. This discovery helps to explain the highly diverse color patterns among bumble bee species as well as how mimicry -- individuals in an...
Researchers from the Centre for Research in Agricultural Genomics (CRAG) and La Salle-Ramon Llull University, both in Barcelona, Spain, have developed a software that, through image processing and machine learning, allows researchers to semi-automate the analysis of root...
Big brains can help an animal mount quick, flexible behavioral responses to frequent or unexpected environmental changes. But some birds just don't need 'em. A global study comparing 2,062 birds finds that, in highly variable environments, birds tend to...
It was the most serious release of radioactive material since Fukushima 2011, but the public took little notice of it: In September 2017, a slightly radioactive cloud moved across Europe. Now, a study has been published, analyzing more...
University of Maryland researchers analyzed an evolutionary tree reconstructed from the DNA of a majority of known bat species and found four bat lineages that exhibit extreme longevity. They also identified, for the first time, two life history...
One of the last remaining megaherbivores, forest elephants shape their environment by serving as seed dispersers and forest bulldozers as they eat over a hundred species of fruit, trample bushes, knock over trees and create trails and clearings....
Differences in numbers of vertebrae are most extreme in mammals which do not rely on running and leaping, such as those adapted to suspensory locomotion like apes and sloths, a team of anthropologists has concluded in a study...
