Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale -- and possibly trigger climatic and environmental effects at a global scale. http://www.physorg.com/news172766088.html Space & Earth Mon, 21 Sep 2009 15:36:23 EST news172766088 On the heels of his discovery in Montana of the first trace fossil of a dinosaur burrow, Emory University paleontologist Anthony Martin has found evidence of more dinosaur burrows - this time on the other side of the world, in Victoria, Australia. The find, to be published this month in Cretaceous Research, suggests that burrowing behaviors were shared by dinosaurs of different species, in different hemispheres, and spanned millions of years during the Cretaceous Period, when some dinosaurs lived in polar environments. http://www.physorg.com/news166471265.html Other Sciences Fri, 10 Jul 2009 19:20:01 EST news166471265 An international team of researchers has studied the coralline algae fossils that lived on the last coral reefs of the Mediterranean Sea between 7.24 and 5.3 million years ago. Mediterranean algae and coral reefs began to resemble present day reefs following the isolation of the Mediterranean from the Indian Ocean and global cooling 15 and 20 million years ago respectively. http://www.physorg.com/news166181578.html Other Sciences Tue, 07 Jul 2009 10:36:55 EST news166181578 Particles cool down the climate, but to which extent? This has remained an unanswered question for scientists. A new article in Science by Gunnar Myhre at CICERO, Norway, brings the scientific community a step closer to solving the mystery. http://www.physorg.com/news164613355.html Space & Earth Fri, 19 Jun 2009 07:10:01 EST news164613355 Millions of years ago, rivers ran in Antarctica through craggy mountain valleys that were strangely similar to the European Alps of today, Chinese and British scientists reported on Wednesday. http://www.physorg.com/news163254239.html Space & Earth Wed, 03 Jun 2009 13:24:29 EST news163254239 (PhysOrg.com) -- The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling. http://www.physorg.com/news150642726.html Biology Thu, 08 Jan 2009 13:12:06 EST news150642726
