August 1, 2013 All told, the scientist has discovered 131 new species of animals in his career, and some are so scary-looking, he's named them after demons. It's a task that's taken more than 30 years of crawling through rain forests to accomplish, and Longino says he's still only scratched the surface.
July 24, 2013 Deep-sea natural gas reservoirs sometimes contain oil, but experts say it's highly unlikely Tuesday's accident in the Gulf of Mexico would leak anything like the BP spill. And there are signs suggesting the only thing crews have to deal with is leaking gas.
July 21, 2013 Fire is a natural part of the western landscape, and a push over the last century to eliminate fires has threatened the habitats that some plants and animals need. In a Montana valley, fire scientists are trying to show that they can actually save wilderness by burning it.
July 18, 2013 Over the past decade, fires in the American West have grown in intensity and size. "We're on a growth trajectory that is very scary," says one fire tracker. "And if we think it's expensive and dangerous now, we're just now seeing the very beginnings of how big this problem is going to be very soon."
July 16, 2013 A fossilized tyrannosaur tooth found lodged between bones in a hadrosaur's tail is giving paleobiologists pretty firm clues about the tyrant king's meal plan. And Hollywood may have been right all along — T. Rex definitely knew how to kill.
July 11, 2013 Pumping industrial wastewater into storage wells deep underground can prime nearby faults for an earthquake. And studies show that a large quake — even one on the other side of the planet — can also push faults over the edge and set off a swarm of mini-earthquakes.
July 10, 2013 The chicken-size sage grouse is as much a part of America's Western range as antelopes and cowboys. The birds nest beneath sagebrush, and as it disappears, so do the grouse. Biologists hope to protect the bird without starting a 21st century range war.
July 2, 2013 Nuclear bomb tests in the 1950s and '60s pumped a lot of radiocarbon into the atmosphere. It went everywhere, including into plants that elephants eat. By measuring the levels of this carbon in elephant tusks, scientists can tell when an elephant died — and whether the ivory is being traded illegally.
May 31, 2013 As humans have cut into Brazil's forests, the toucan population has taken a dive. The trees, in turn, have changed, too: Without large-billed birds to eat fruit with big seeds, only trees with small seeds thrive. Eventually, one scientist says, "the impacts on the forest could be quite dramatic."
May 14, 2013 By the end of the century, ocean levels could rise by 2 or 3 feet. That's enough to flood the colonists' first settlement at Jamestown, Va. And it's putting pressure on archaeologists to get as many artifacts out of the ground as quickly as possible — before it's too late.
May 1, 2013 The winter of 1609-1610 has been called the "starving time" for the hundreds of men and women who settled the English colony of Jamestown, Va. They ate their horses, their pets — and, apparently, at least one person. Scientists say human bones recovered from the site provide the first hard evidence that the colonists may have resorted to cannibalism.
