NASA catalogs thousands of asteroids near Earth
Thu,8 Dec 2011 05:03 AM PST
Reuters -  SAN FRANCISCO (Reuters) - About 1,000 asteroids big enough to cause catastrophic damage if they hit Earth are orbiting relatively nearby, a NASA survey shows. In a project known as Spaceguard, the U.S. space agency was ordered by Congress in 1998 to find 90 percent of objects near Earth that are 1 km (0.62 of a mile) in diameter or larger. The survey is now complete, with 93 percent of the objects accounted for, astronomer Amy Mainzer of NASA's Jet Propulsion Laboratory in Pasadena, California, said at the American Geophysical Union conference in San Francisco on Tuesday. ...

Top-grade stem cells seen boosting research trials
Wed,7 Dec 2011 05:14 AM PST
Reuters -  LONDON (Reuters) - British scientists have made the first human embryonic stem cells of a high enough grade to use in patients and deposited them in a public stem cell bank for development in human trials by drug companies and researchers by 2014. A team from King's College London said on Monday they were submitting two clinical-grade stem cell lines to the UK Stem Cell Bank (UKSBC), which will test and validate them before offering them to researchers. This could speed the path towards new stem-cell treatments for conditions like blindness, severe injury or heart disease. ...

"Big Three" polluters oppose binding climate deal
Tue,6 Dec 2011 11:22 AM PST
Reuters -  DURBAN, South Africa (Reuters) - The world's three biggest polluters China, the United States and India refused to move toward a new legal commitment to curb their carbon emissions Tuesday, increasing the risk that climate talks will fail to clinch a meaningful deal this week. The European Union is leading efforts to keep alive the Kyoto Protocol, the world's only legal pact to tackle climate change, with a conditional promise to sign a global deal that would force big emitters to change their ways. But with the planet's biggest polluters digging in their heels, U.N. ...
