(PhysOrg.com) -- Roughly 15,000 years ago, at the end of the last ice age, North America's vast assemblage of large animals -- including such iconic creatures as mammoths, mastodons, camels, horses, ground sloths and giant beavers -- began their precipitous slide to extinction. http://www.physorg.com/news177864298.html Space & Earth Thu, 19 Nov 2009 14:45:49 EST news177864298 (PhysOrg.com) -- Snakes coil up when they sense danger. Some snakes curl up in order to spring into action and strike. Snakes may also coil to preserve body heat, and this warming behavior could affect our understanding of ancient climates. http://www.physorg.com/news168536616.html Other Sciences Mon, 03 Aug 2009 16:44:48 EST news168536616 Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years. http://www.physorg.com/news164303941.html Space & Earth Mon, 15 Jun 2009 18:00:01 EST news164303941 (AP) -- Scientists at one of Utah's major new dinosaur quarries have found 60 to 70 new bones this spring, including what appears to be a 20-foot-long neck bone discovered this week. http://www.physorg.com/news163395992.html Other Sciences Fri, 05 Jun 2009 04:46:57 EST news163395992 Researchers at the California Institute of Technology (Caltech) and their colleagues have found evidence of ancient climate change on Mars caused by regular variation in the planet's tilt, or obliquity. On Earth, similar "astronomical forcing" of climate drives ice-age cycles. http://www.physorg.com/news147623815.html Space & Earth Thu, 04 Dec 2008 14:36:55 EST news147623815
