Cloning, Stem Cells Long Mired In Legislative Gridlock

After President Obama overturned Bush-era policy restricting federal funding of embryonic stem cell research in 2009, Nebraska Right to Life led a protest of the research outside the University of Nebraska regents' meeting.

The news that U.S. scientists have successfully cloned a human embryo seems almost certain to rekindle a political fight that has raged, on and off, since the announcement of the creation of Dolly the sheep in 1997.

Water Trapped For 1.5 Billion Years Could Hold Ancient Life

This map, from the United States Geological Survey, shows the age of bedrock in different regions of North America. Scientists found ancient water in bedrock north of Lake Superior. This region, colored red, was formed more than 2.5 billion years ago.

Scientists have discovered water that has been trapped in rock for more than a billion years. The water might contain microbes that evolved independently from the surface world, and it's a finding that gives new hope to the search for life on other planets.

The water samples came from holes drilled by gold miners near the small town of Timmins, Ontario, about 350 miles north of Toronto. Deep in the Canadian bedrock, miners drill holes and collect samples. Sometimes they hit pay dirt; sometimes they hit water, which seeps out from tiny crevices in the rock.

NASA Says Kepler's Planet-Searching Days May Be Numbered

Kepler-22b, the discovery of which was announced in December 2011, is one of many planets that bear the space telescope's name.

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.

Dam Removal Ushers In New Life In Washington State

AUDIE CORNISH, HOST:

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.

How Scientists Cloned Human Embryos

Human embryos grow in a petri dish two days after scientists in Oregon cloned them from a donor's skin cell.

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.
