Water Trapped For 1.5 Billion Years Could Hold Ancient Life

Scientists have discovered water that was sealed in Canadian bedrock for nearly half of Earth's history. It may contain the descendants of ancient microbes. The discovery could give scientists new insights into early life on Earth and inform the search for life on other planets.

Cloning, Stem Cells Long Mired In Legislative Gridlock

The news that scientists have successfully cloned a human embryo seems almost certain to rekindle a political fight that has raged, on and off, since the creation of Dolly the sheep. It's a fight that has, over the past decade and a half, produced a lot of heat and light and not a lot of policy.

Dam Removal Ushers In New Life In Washington State

New life is coming to Washington State's Olympic Peninsula. Two dams along the Elwha River are being removed, bringing a rush of sediment downstream and exposing hundreds of acres of once-submerged land. The dams were built in the early 1900s to power nearby timber mills. But they blocked salmon migration and their power is no longer needed, so they're coming out. This story originated as part of the public media collaboration, EarthFix.

How Researchers Cloned Human Embryos

After decades of trying, scientists say they've finally figured out how to make personalized embryonic stem cells. One day, these designer cells may help treat an array of diseases. A jolt of caffeine and and a little electric shock helped to do the trick.

Analyzing The Language Of Suicide Notes To Help Save Lives

About a third of people who attempt suicide leave a note. John Pestian and others at Cincinnati Children's Hospital are merging psychology and computer analysis to see if such notes can help diagnose suicidal tendencies in the living.

Scientists Clone Human Embryos To Make Stem Cells

The achievement is a long-sought step toward harnessing the potential power of such cells to treat diseases. But the discovery raises ethical concerns because it brings researchers closer to cloning humans.
