Neanderthals May Have Sailed to Crete
Neanderthals, or even older Homo erectus (“Upright Man”) might have sailed around the Mediterranean, stopping at islands such as Crete and Cyprus, new evidence suggests. The evidence suggests that these hominid species had considerable seafaring and cognitive skills. “They had to have had boats of some sort; unlikely they swam,” said Alan Simmons, lead author…
Ancient Microbes Found in Buried Antarctic Lake
Beneath the icy surface of a buried Antarctic lake, in super-salty water devoid of light and oxygen that is also cold enough to freeze seawater, researchers have now discovered that a diverse community of bacteria has survived for millennia. The findings, detailed online in the journal Proceedings of the National Academy of Sciences, shed light…
Early Human ‘Lucy’ Swung From the Trees
Despite the ability to walk upright, early relatives of humanity represented by the famed “Lucy” fossil likely spent much of their time in trees, remaining very active climbers, researchers say. Humans are unique among living primates in that walking bipedally — on two feet — is humans’ chief mode of locomotion. This upright posture freed…

The Border Between Primordial Plasma and Ordinary Matter
Scientists taking advantage of the versatility and new capabilities of the Relativistic Heavy Ion Collider (RHIC), an atom smasher at the U.S. Department of Energy’s Brookhaven National Laboratory, have observed first glimpses of a possible boundary separating ordinary nuclear matter, composed of protons and neutrons, from the seething soup of their constituent quarks and gluons…
At the End of the Earth, Seeking Clues to the Universe
The same conditions that make the Atacama, Earth’s driest desert, so inhospitable make it beguiling for astronomy. In northern Chile, it is far from big cities, with little light pollution. Its arid climate prevents radio signals from being absorbed by water droplets. The altitude, as high as the Himalaya base camps for climbers preparing to…
