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 ...
In a sticky sting operation, researchers may have nabbed the last toxic members of a honey-tainting ring in New Zealand.
Cloaked in sugars, two forms of tutin — a potent neurotoxin that can cause delirium and seizures — have been found lurking in poisoned honey, researchers report online May 21 in the Journal of...
The creature emerged from the murky depths of Florida’s Crystal River just a couple of feet below where I was floating. I froze and felt my eyes widen. I wanted to shout “manatee!” but knew that would scare the animal. And that was the last thing I wanted to do.
Before I even dipped a toe in the water, I had been drilled about the rules of passive observation. “You have to be really...

Warming waters will boost the destructiveness of future typhoons, new research predicts.
Studying 60 years of typhoon activity in the western Pacific Ocean, researchers spotted a clear trend: A typhoon’s ultimate intensity largely depends on the temperature of deep seawater churned upward as the storm passes overhead. Projecting their finding into the future, the researchers...
There are some 3 million shipwrecks scattered across the ocean floor, UNESCO has estimated, and most of them are still waiting to be found. One of those ships, which sank off the French coast in 1843, carried a treasure trove of science — most of the papers and research...
