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…

La flora bacteriana del pelo de la zona vaginal es diferente en cada persona, según un estudio pionero

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…

Bakterioek beharrezkoa dute burdina bizitzeko. Eta, horregatik, bakterioen aurkako defentsa-mekanismo bat da burdina eskuragarri ez uztea. Hori eraginkorra da bakterioek burdin hori eskuratzeko mekanismoren bat lortzen duten arte. Bada, burdinagatiko borroka horretan gutxienez 40 milioi urte daramatzate primateek eta bakterioek,Science aldizkarian argitaratu berri den lan baten arabera.

The footage captures a neuron firing, letting researchers watch the signal flowing through an entire cell for the first time. Seeing these cells at work may let researchers track and measure brain activity, including firing patterns of cells affected by disorders like epilepsy or multiple sclerosis.
