New technologies can improve agricultural sustainability in developing countries, but only with the engagement of local farmers and the social and economic networks they depend on, say Stanford University researchers. Their findings are published in the May 23 online edition of the Proceedings of the National Academy of Sciences (PNAS). http://phys.org/news226228419.html Space & Earth Thu, 02 Jun 2011 10:13:58 EST news226228419 Can you bring something back from the dead? Scientists in Sweden say that if it's at the bottom of the sea and oxygenation is present, you can. Oxygenation gives ecosystems the boost they need to come to life and helps nature deal with eutrophication, the bloom of phytoplankton in water. http://phys.org/news224847579.html Space & Earth Tue, 17 May 2011 10:39:54 EST news224847579 (PhysOrg.com) -- The Spacecraft Assembly Facility of NASA's Jet Propulsion Laboratory in Pasadena, Calif., was constructed in 1961 to support NASA's Ranger and Mariner missions to the moon, Venus and Mars. http://phys.org/news224496540.html Space & Earth Fri, 13 May 2011 09:09:31 EST news224496540 The Mid-latitude Airborne Cirrus Properties Experiment (MACPEX) is a NASA field campaign that is investigating cirrus cloud properties and the processes that affect their impact on solar radiation.
