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.

NEAL CONAN, HOST:

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.

Go Fish (Somewhere Else): Warming Oceans Are Altering Catches

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.

Road Crew In Belize Destroys Ancient Pyramid

What's left of the Nohmul pyramid after a construction crew virtually destroyed the 2,300-year-old Mayan structure.

A construction crew in search of gravel to use as road filler used its backhoes to level one of Belize's largest Mayan pyramids.

"It's a feeling of incredible disbelief because of the ignorance and the insensitivity ... they were using this for road fill," Jaime Awe, the head of the Belize Institute of Archaeology, said of the destruction at the 2,300-year-old Nohmul pyramid, located in the Orange Walk/Corozal area.

"It's like being punched in the stomach. It's just so horrendous," Awe said Monday of the destruction thought to have occurred last week.
