Taking a systems biology approach, the bioengineers and medical researchers also determined how a common class of drugs for treating insulin resistance -- TZDs -- alter these same core pathways. This led the team to uncover previously unknown effects of TZDs and insights that could lead to improved drug therapies for insulin resistance. http://www.physorg.com/news178200964.html Medicine & Health Mon, 23 Nov 2009 12:16:46 EST news178200964 A new calculation of Europe's greenhouse gas balance shows that emissions of methane and nitrous oxide tip the balance and eliminate Europe's terrestrial sink of greenhouse gases. http://www.physorg.com/news178200670.html Space & Earth Mon, 23 Nov 2009 12:12:17 EST news178200670 A new species of chameleon has been discovered in Tanzania by a team of scientists. http://www.physorg.com/news178199221.html Biology Mon, 23 Nov 2009 11:50:01 EST news178199221 (AP) -- The world's largest atom smasher made another leap forward Monday by circulating beams of protons in opposite directions at the same time in the $10 billion machine after more than a year of repairs, organizers said. http://www.physorg.com/news178198886.html Physics Mon, 23 Nov 2009 11:42:04 EST news178198886
