(Phys.org)—By studying the origins of different isotope ratios among the elements that make up today's smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust, Mark Thiemens and his colleagues hope to learn how our solar system evolved. Thiemens, Dean of the Division of Physical Sciences at the University of California, San Diego, has worked on this problem for over three decades. http://phys.org/news280588310.html Space & Earth Wed, 20 Feb 2013 13:12:02 EST news280588310 (Phys.org) -- Is Earth really a sort of giant living organism as the Gaia hypothesis predicts? A new discovery made at the University of Maryland may provide a key to answering this question. This key of sulfur could allow scientists to unlock heretofore hidden interactions between ocean organisms, atmosphere, and land -- interactions that might provide evidence supporting this famous theory. http://phys.org/news256321026.html Space & Earth Tue, 15 May 2012 17:17:21 EST news256321026 There have been instances in Earth history when average temperatures have changed rapidly, as much as 10 degrees Celsius (18 degrees Fahrenheit) over a few decades, and some have speculated the same could happen again as the atmosphere becomes overloaded with carbon dioxide. http://phys.org/news227781558.html Space & Earth Mon, 20 Jun 2011 09:39:48 EST news227781558 (PhysOrg.com) -- Analyzing the isotope ratios of ancient raindrops preserved in soils and lake sediments, Stanford researchers have shown that a wave of mountain building began in British Columbia, Canada about 49 million years ago and rolled south to Mexico. The finding helps put to rest the idea that there was once a Tibet-like plateau across the western US that collapsed and eroded into the mountains we see today. http://phys.org/news211806507.html Space & Earth Fri, 17 Dec 2010 11:10:31 EST news211806507
