Neandertals knew how to accessorize. Eight 130,000-year-old eagle talons unearthed in Croatia show signs of being strung together and worn as a necklace or bracelet, as Bruce Bower reported in “Cache of eagle claws...
As any physicist will tell you, chemistry is really all about physics. But while physical understanding of atoms and their quantum nature has progressed by leaps and bounds in the last century, not all of those insights have produced radical changes in chemistry. A mix of...
After my second daughter was born, I was prepared to wait three or four days for my breast milk to come in, as I had with my first. But just as everyone had warned, things were completely different the second time around. Just half a day later, my body was already churning out the good stuff.
“She’s already got a milk mustache!” one of the nurses told me as she weighed my newborn. That...
When researchers operating the Large Hadron Collider, or LHC, outside Geneva discovered the Higgs boson, it ended a decades-long effort to fill the final gap in physicists’ catalog of matter’s particles and forces. Now comes the hard part. Physicists know that their catalog is only a start; there’s far more to the universe that needs to be explained. But the LHC’s first round of results...
Chimpanzees not only understand what it means for food to be cooked but prefer roasted over raw grub. Mental skills needed for cooking may have thus existed 7 million years ago or more, in the last common ancestor of apes and humans, researchers propose June 3 in Proceedings of the Royal Society B....
A crippling virus has slipped its bonds in Africa and Asia and is invading whole new continents faster than people canlearn to pronounce its name. In one decade, chikungunya (chihk-uhn-GUHN-yuh) fever has gone from an obscure tropical ailment to an international threat, causing more than 3 million infections worldwide. The virus has established itself in Latin America and may now have the...
Update your maps: Two new islands have popped up in the strip of ocean between Africa and the Arabian Peninsula.
Witnessing the birth of a volcanic island is incredibly rare, but thanks to satellite images, researchers from the King Abdullah University of Science and Technology in Thuwal, Saudi Arabia, retraced the formation of two islands in the Red Sea.
The new islands, called...
The ultimate telescope upgrade lies about 3.5 billion light-years away in the constellation Sculptor.
Abell 2744 (below) is a galaxy cluster whose tremendous mass — equivalent to 2 quadrillion suns — turns it into a gravitational lens that bends and magnifies light from distant objects. This effect allows astronomers to peer farther into space than any telescope can do alone. By studying...
Humans and dogs aren't the only ones that can pass along yawns. They appear to be contagious among parakeets, too.
Videos taken in 2012 of budgie flocks suggested that yawns and stretches spread among the birds. A new study now shows that when one ...
