Research News
May 18, 2013 — Atmospheric scientist Ira Leifer installed special air sensors on a camper, then drove from Florida to California, measuring methane levels all along the way. More than 6,000 readings later, he found some noticeable spikes, especially around petrochemical plants and urban areas like Los Angeles.
May 17, 2013 — Scientists reported this week in the journal Cell that they had used somatic cell nuclear transfer techniques to create a source of embryonic stem cells from the skin cells of a patient. George Daley, director of the stem cell transplantation program at Boston Children's Hospital, and Josephine Johnston of the Hastings Center discuss the research.
May 16, 2013 — The results are preliminary, and alpha parents seeking an edge for their children shouldn't risk electrocution. Still, the findings are provocative and may lead researchers down a new road.

May 16, 2013 — Scientists in Oregon have achieved something that has eluded researchers for years. They have created stem cells that are tailored to individual patients, made from cloned embryos. That would open the door to treating many diseases, including Alzheimer's, Parkinson's, diabetes, spinal cord injuries and many others. But researchers face ethical dilemmas.
May 16, 2013 — 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.
May 15, 2013 — 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.

May 15, 2013 — Fish are moving away from the equator and toward the poles to maintain their preferred water temperature. That means, for example, that fishermen are seeing swordfish normally found in the Mediterranean swimming near Denmark. But in the tropics, there are no fish to replace the ones that are leaving.
May 15, 2013 — 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.
May 14, 2013 — By the end of the century, ocean levels could rise by 2 or 3 feet. That's enough to flood the colonists' first settlement at Jamestown, Va. And it's putting pressure on archaeologists to get as many artifacts out of the ground as quickly as possible — before it's too late.
May 13, 2013 — The appeal of owning your own property — and all the private goods that came with it — may have convinced nomadic humans to settle down and take up farming. So says a new study that tried to puzzle out why early farmers bothered with agriculture.
