A mysterious basin off the coast of India could be the largest, multi-ringed impact crater the world has ever seen. And if a new study is right, it may have been responsible for killing the dinosaurs off 65 million years ago. http://www.physorg.com/news174827113.html Space & Earth Thu, 15 Oct 2009 12:06:03 EST news174827113 Those lyin', cheatin' green consumers. Just being around green products can make us behave more altruistically, a new study to be published in a forthcoming issue of Psychological Science has found. http://www.physorg.com/news174140623.html Medicine & Health Wed, 07 Oct 2009 13:40:01 EST news174140623 The asteroid impact that many researchers claim was the cause of the dinosaur die-off was bad news for marine life at the time as well. But new research shows that microalgae - one of the primary producers in the ocean - bounced back from the global extinction in about 100 years or less. http://www.physorg.com/news173713660.html Space & Earth Fri, 02 Oct 2009 15:10:01 EST news173713660 Human activities have meant invasive species have been able to populate parts of the world to which they are not native and alter biodiversity there over thousands of years. Now, an international team of scientists has studied the impact of the black rat on bird populations on Mediterranean islands. Despite the rat's environmental impact, only the tiny European storm petrel has been affected over time by its enforced cohabitation with the rat. http://www.physorg.com/news173696887.html Biology Fri, 02 Oct 2009 10:20:14 EST news173696887 An Australian town pulled all bottled water from its shelves Saturday and replaced it with refillable bottles in what is believed to be a world-first ban. http://www.physorg.com/news173168696.html Space & Earth Sat, 26 Sep 2009 08:10:01 EST news173168696 (PhysOrg.com) -- Sustaining a second concussion shortly after a first one can lead to serious problems for young athletes, making it extremely important for players to be correctly diagnosed after being hit in the head. http://www.physorg.com/news172857276.html Medicine & Health Tue, 22 Sep 2009 17:10:02 EST news172857276 Molecules vital to life have been detected in outer space and isolated in meteorites and comets. Some of this material that rained down on Earth may have jump-started biology. If so, these space seeds also may have planted a particular molecular orientation, or "handedness," that spread to the world's first creatures. New research is studying how this handedness could arise in space. http://www.physorg.com/news172502439.html Space & Earth Fri, 18 Sep 2009 14:30:01 EST news172502439 (PhysOrg.com) -- NASA's first-ever moon temperature-mapping effort has returned its first data. http://www.physorg.com/news172424963.html Space & Earth Thu, 17 Sep 2009 16:51:32 EST news172424963 (PhysOrg.com) -- NASA reported Thursday that its Lunar Reconnaissance Orbiter, or LRO, has successfully completed its testing and calibration phase and entered its mapping orbit of the moon. http://www.physorg.com/news172417835.html Space & Earth Thu, 17 Sep 2009 15:20:01 EST news172417835 Scientists from the Universities of Exeter and Plymouth are today calling for urgent research to understand the impact of renewable energy developments on marine life.

But the unintended costs to the environment and human health have been substantial. Nitrogen runoff from farms has contaminated surface and groundwater and helped create massive `dead zones` in coastal areas, such as the Gulf of Mexico. And ammonia from fertilized cropland has become a major source of air pollution, while emissions of nitrous oxide form a potent greenhouse gas. http://www.physorg.com/news164918496.html Space & Earth Mon, 22 Jun 2009 20:20:01 EST news164918496 US startup Hara on Monday made a public debut with a service that shows businesses, organizations and governments how to profit from being Earth friendly. http://www.physorg.com/news163056957.html Technology Mon, 01 Jun 2009 06:36:35 EST news163056957 (PhysOrg.com) -- Since the early 1990s astronomers have discovered more than 300 planets orbiting stars other than our sun, nearly all of them gas giants like Jupiter.
