The birds left one to two full days before we humans had seen any sign of it. When they began their travels, there was no change discernible in wind speed or direction, in barometric pressure or temperature. The birds had somehow known a very violent storm was coming, which might have killed them with its…

Every cell in your body reads the same genome, the DNA-encoded instruction set that builds proteins. But your cells couldn’t be more different. Neurons send electrical messages, liver cells break down chemicals, muscle cells move the body. How do cells employ the same basic set of genetic instructions to carry out their own specialized tasks?…

Discovery of hydrogen-rich waters hints at unexplored microbial ecosystems.

There are places on comet 67P/Churyumov-Gerasimenko where cauliflowerlike textures appear in the dusty crust, like goose bumps under the skin. Scientists using theRosetta spacecraft—which arrived at 67P in August and became the first mission to orbit and land on a comet—now think they may have discovered the source of these patterns on cliff faces and…

Can mechanical forces alone be manipulated to create stem-like cells?

Although a water app isn’t close yet, researchers at Corning and elsewhere recently discovered that they could use Gorilla Glass, the toughened glass made by Corning that’s commonly used on smartphone screens, to make extremely sensitive chemical and biological sensors. It could detect, say, traces of sarin gas in the air or specific pathogens in…

Long periods without sunshine can play a role in a surprising variety of physical and mental disorders

Un equipo de investigadores de instituciones norteamericanas, liderado por un español, ha encontrado 53 compuestos con actividad potencial frente al virus del ébola. Las moléculas proceden de otros fármacos que ya han demostrado ser seguros contra otras dolencias en humanos. Los autores del trabajo creen que este método podría acelerar el hallazgo de tratamientos contra…
