The Cascades frog used to occupy alpine zones from California to the Canadian border, but its range is shrinking as global temperatures increase and snowpack declines. Scientists are hiking deep into the mountains of the Northwest to study the tiny frog, which makes a call that has been described as a "chuckling" sound.
Scientists have known that dolphins recognize each other by the sound of each animal's signature whistle. But new research shows that dolphins remember and respond to these whistles for an incredibly long time — even after they've been separated from each other.
Late summer tends to be a slow month for news. But at All Things Considered, we put on a two hour program, no matter what. So — without a trace of irony — one of our science correspondents offered to help fill some holes in the show with a series of stories about holes. In this edition: Black holes.
A special committee that includes two members of the Lacks family will review scientists' applications for access to the genetic sequence of cells derived from a tumor that killed Henrietta Lacks. The cells are among the most widely used in research.
A small, square sticker called the Kite Patch promises to keep mosquitoes away by sending out chemicals that block the bug's ability to sense humans. The inventors say it could be a game changer in the way we prevent mosquito-borne illnesses like West Nile virus.
Chinese scientists offer the first clear evidence that the H7N9 bird flu virus can be transmitted from human to human. A father, who became sick in March, passed the virus to his daughter. But the risk of transmission is quite low, and the virus still doesn't appear to pose a global threat.
The federal government's top climate scientists announced Tuesday that 2012 was really hot — among the top 10 hottest years on record and the hottest ever in the U.S., with rising sea levels, less Arctic sea ice and warmer oceans. And the American Geophysical Union called humanity "the major influence" on global climate change.
New pumping and irrigation systems made it easy for farmers to extract billions of gallons of water from the High Plains Aquifer. But now, parts of the aquifer are dried out, prompting a debate over how to preserve what once seemed to be an almost inexhaustible resource.
A new study published in The Journal of the American Medical Association says the rising number of suicides in the military cannot be blamed on deployments to Iraq and Afghanistan. But other studies say there is a link and many researchers caution that the factors leading to suicide are complex and unique for each individual, so they question whether the findings should guide treatment.
