Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically cooled the planet, and contributed to the mass extinction that […]

Scientists found a gene variant that affects cholesterol levels also could increase the risk of contracting typhoid fever. A common cholesterol-lowering drug could protect animal models against Salmonella Typhi, the culprit behind the potentially deadly infection. The findings give insight into the mechanisms that govern human susceptibility to infectious disease […]
Scientists are working toward a better understand whether cyanobacteria can be grown for biofuels on a large scale.
The most ideal place to view a solar eclipse is not always on the ground — the best seats in the house might belong to the people who are midair as the moon passes in front of the sun and covers a circular patch of Earth in darkness. There are […]
The 2017 total solar eclipse that is passing across the United States today could be a once-in-a-lifetime opportunity for a lot of people to see the moon completely block out the sun, but it’s best if they don’t commemorate the event by taking a selfie. According to retina expert Dr. […]
Scientists studying microbes from some of the saltiest lakes in Antarctica have discovered a new way the microbes can share DNA that could help them grow and survive. The research, based on 18 months of water sampling in remote Antarctic locations, could throw light on the evolutionary history of viruses. […]
Advanced technologies has been used to illuminate the connectivity pattern of chandelier cells, a distinctive kind of inhibitory cell type in the mammalian brain. Scientists reveal for the first time how this candelabra-shaped cell interacts in a highly selective way with hundreds of excitatory cells in its neighborhood, receiving information […]
A longstanding obstacle to the market for bovine embryos is about to be removed. Researchers have described a hitherto unknown mechanism of lipid accumulation in oocytes that limits the success of in vitro production of bovine embryos.
