The planet-hunting career of NASA's Kepler spacecraft might be near its end.
Astronomers said Wednesday that a reaction wheel that keeps the orbiting telescope pointed at tiny, distant patches of sky to look for Earth-like planets has failed. If they can't fix it, Kepler will be relegated to a less prestigious mission, directing its gaze much closer to home in a search for so-called "near-Earth objects," i.e., meteors and asteroids.
The competition for your ears — and dollars — just got a little tougher. On Wednesday, Google launched a paid music subscription service that will put it in direct competition with other streaming services like Spotify and Pandora. The announcement may just be the beginning for Google.
Two dams that block the migration of salmon are coming down in the largest dam removal in U.S. history. The dam sits on the Elwha River in the northwest corner of Washington state. They were built in the early 1900s to power nearby timber mills, but their power is no longer needed. From member station KUOW in Seattle, Ashley Ahearn reports that the removal is releasing a lot of debris but also creating new life.
Scientists in Oregon have achieved something that many thought might be impossible.
They said Wednesday that they have cloned human embryos and then harvested the embryo's stem cells.
The discovery, if it holds up, means scientists would be able to make personalized stem cells, with their genetic code almost perfectly matched to that of a patient.
Every 14 minutes, someone in this country commits suicide, and research on ways to reduce that grim statistic appears to be on a plateau. In other words, psychologists don't have much in the way of new ideas - at least, right now - except maybe for what's described as groundbreaking work on the notes that those who kill themselves sometimes leave behind. A team of researchers at the Cincinnati Children's Hospital use computers to break down the language in these messages of despair, in the hope that they can better identify those at risk.

Crew members unload a catch of sockeye salmon at Craig, Alaska, in 2005. Researchers say fish are being found in new areas because of changing ocean temperatures.
Climate change is gradually altering the fish that end up on ice in seafood counters around the world, according to a new study.
"The composition of the [global] fish catch includes more and more fish from the warmer areas, and cold-water fish are getting more rare, because the temperatures are increasing," says Daniel Pauly at the University of British Columbia, a co-author of the study.
Scientists say they have, for the first time, cloned human embryos capable of producing embryonic stem cells.
The accomplishment is a long-sought step toward harnessing the potential power of embryonic stem cells to treat many human diseases. But the work also raises a host of ethical concerns.
It turns out that the desire to speak with Apple CEO Tim Cook, along with $610,000, will buy you a cup of coffee. That's the winning bid offered in a charity auction for up to an hour of Cook's time.
As we reported last month, the chance to grab coffee with Cook at Apple's headquarters zoomed past the suggested value of $50,000 set at the Charitybuzz auction site, rising to more than $600,000 in just three days.
