(PhysOrg.com) -- We've all read studies about the health benefits of having a life partner. The same thing is true at the molecular level, where amino acids known as cysteines are much more vulnerable to damage when single than when paired up with other cysteines. http://www.physorg.com/news177873745.html Chemistry Thu, 19 Nov 2009 17:23:18 EST news177873745 (PhysOrg.com) -- Cornell scientists have discovered how two related proteins and their roles in a key molecular pathway are critical to creating obesity-causing fat cells. http://www.physorg.com/news163266213.html Medicine & Health Wed, 03 Jun 2009 16:44:35 EST news163266213 Dengue fever is the most common infectious disease transmitted by mosquitoes - some 100 million people around the world are infected. Researchers at the Hygiene Institute at Heidelberg University Hospital were the first to present a three-dimensional model of the location in the human cell where the virus is reproduced. http://www.physorg.com/news160921558.html Biology Thu, 07 May 2009 13:26:25 EST news160921558 Michigan State University plant scientists have discovered another piece of the genetic puzzle that controls how plants respond to high temperatures. That may allow plant breeders to create new varieties of crops that flourish in warmer, drier climates. http://www.physorg.com/news142564476.html Biology Tue, 07 Oct 2008 02:14:36 EST news142564476 Researchers at the University of Pennsylvania School of Medicine have shown that the unfolded protein response, which is a reaction to stress induced by sleep deprivation, is impaired in the brains of old mice. http://www.physorg.com/news133784411.html Medicine & Health Fri, 27 Jun 2008 11:20:11 EST news133784411
