It's no secret that the emissions leaving a car tailpipe or factory smokestack affect climate and air quality. Even trees release chemicals that influence the atmosphere. But until now, scientists have struggled to know where these organic molecules go and what happens to them once they leave their source, leading to models for predicting climate and air quality that are incomplete or less than accurate. http://www.physorg.com/news179677214.html Space & Earth Thu, 10 Dec 2009 14:50:04 EST news179677214 (PhysOrg.com) -- A galaxy located billions of light-years away is commanding the attention of NASA's Fermi Gamma-ray Space Telescope and astronomers around the globe. Thanks to a series of flares that began September 15, the galaxy is now the brightest source in the gamma-ray sky -- more than ten times brighter than it was in the summer. http://www.physorg.com/news179593672.html Space & Earth Wed, 09 Dec 2009 16:40:01 EST news179593672 When Microsoft starts selling Office 2010 next year, the company will take its workhorse software suite and move it one step closer to its vision of cloud computing. http://www.physorg.com/news179134570.html Technology Fri, 04 Dec 2009 08:10:03 EST news179134570 Li et al. explain how prolonged stress sparks the endoplasmic reticulum (ER) to release its calcium stores, inducing cells to undergo apoptosis in several aging-related diseases.The study will appear in the September 21, 2009 issue of the Journal of Cell Biology (online September 14). http://www.physorg.com/news172150633.html Biology Mon, 14 Sep 2009 13:00:01 EST news172150633 Carbon nanotubes hold many exciting possibilities, some of them in the realm of the human nervous system.

Now, a mathematical model developed by MIT engineers can predict whether particular types of stents are likely to cause life-threatening side effects. http://www.physorg.com/news150473094.html Other Sciences Tue, 06 Jan 2009 14:04:54 EST news150473094 For risk-takers and impulsive people, New Year's resolutions often include being more careful, spending more frugally and cutting back on dangerous behavior, such as drug use. But new research from Vanderbilt finds that these individuals--labeled as novelty seekers by psychologists--face an uphill battle in keeping their New Year's resolutions due to the way their brains process dopamine. The research reveals that novelty seekers have less of a particular type of dopamine receptor, which may lead them to seek out novel and exciting experiences--such as spending lavishly, taking risks and partying like there's no tomorrow. http://www.physorg.com/news149838584.html Medicine & Health Tue, 30 Dec 2008 05:49:44 EST news149838584 Rube Goldberg -the cartoonist who devised complex machines for simple tasks -would have smiled at one of leptin's mechanisms for curbing insulin release.

One type of cell death activates an immune response while another type doesn't. Now researchers at Washington University School of Medicine in St. Louis and St. Jude's Children's Research Hospital in Memphis have figured out how some dying cells signal the immune system. They say the finding eventually could have important implications in the treatment of autoimmune diseases and cancer. http://www.physorg.com/news135517555.html Medicine & Health Thu, 17 Jul 2008 12:45:55 EST news135517555 In today's issue of the prestigious journal Cell Metabolism Uppsala scientists are presenting new findings that shed light on the processes that determine the release of the blood sugar-lowering hormone insulin.
