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.

Analyzing The Language Of Suicide Notes To Help Save Lives

Originally published on Thu May 16, 2013 1:20 pm

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

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 Clone Human Embryos To Make Stem Cells

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.

People often ask me how I got interested in science. I wish I could answer that I had a mentor when I was a child, that a biologist or a physicist visited my school when I was in third grade and transformed my life. But that's not what happened to me and, sadly, not what happens to the vast majority of children.

Road Crew In Belize Destroys Ancient Pyramid

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.

India, China Could Soon Demand More Oil Than U.S. And Europe

From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.

MELISSA BLOCK, HOST:

And I'm Melissa Block.

For years, we've understood the global oil landscape in fairly simple terms: Saudi Arabia and other Middle Eastern countries were the big producers of oil, the United States and its allies were the big oil buyers. But a report today from the International Energy Agency shows a different picture. Turns out the U.S. has become a star oil producer, as NPR's Tom Gjelten reports.

'Ice Shove' Damages Some Manitoba Homes Beyond Repair

AUDIE CORNISH, HOST:

In northern lakefront vacation spots such as Ochre Beach, Manitoba and Lake Mille Lacs, Minnesota, ice happens even in May. But what happened this past weekend was like something out of a science fiction movie.

MELISSA BLOCK, HOST:

This is the sound from a video recorded as constant strong winds pushed huge sheets of ice off a lake and onto the shore. Fingers of ice creeped farther inland and farther. It's as if the ice is alive.

With Rising Seas, America's Birthplace Could Disappear

By the end of the century, the birthplace of America may be underwater.

The first successful English colony in America was at Jamestown, Va., a swampy island in the Chesapeake Bay. The colony endured for almost a century, and remnants of the place still exist. You can go there and see the ruins. You can walk where Capt. John Smith and Pocahontas walked. But Jamestown is now threatened by rising sea levels that scientists say could submerge the island by century's end.
