So much ice is piling up in the vast expanses of East Antarctica that, overall, it counterbalances the losses seen at glaciers thinning elsewhere on the frozen continent. It will take decades for Antarctic melting to overtake the mass gains and begin contributing substantially to sea-level rise, a new study argues.

Karolinska Institutuak jakinarazi duenez, aurten hiru ikertzaileren artean banatuko dute Fisiologia edo Medikuntzako Nobel saria; erdia William C. Campbell eta Satoshi Ōmura jasoko dute, bizkarroiek eragindako gaitzen aurka asmatutako botikarengatik, eta beste erdia Youyou Tuk, malariaren aurkako terapia asmatzeagatik.

Passionate advocates of organic farming and foods resemble members of a religious cult, one founded on a “back to Nature” mentality. They are not so fundamentalist, however, that they do not make concessions to reality. For example, organic standards arbitrarily define which pesticides are acceptable but allow “deviations” if based on “need.” Synthetic chemical pesticides…

Brand-new babies aren’t capable of much beyond eating (around the clock), pooping (usually all over their cutest onesies) and sleeping (though certainly not at night). But what’s going on inside those tiny heads is nothing short of amazing.

An ancient landslide on an island volcano is providing a worrisome lesson about tsunamis, thanks to some geologic sleuthing. According to a new study in the Cape Verde archipelago, a landslide triggered a tsunami powerful enough to push massive boulders on a neighboring island onto a high plateau. The scientists warn that although such events…

There is no known physics theory that is true at every scale—there may never be.
