(Phys.org) -- How better to find out what effect ionizing radiation has on human skin than by using the real thing? Researchers at Pacific Northwest National Laboratory did that by performing a quantitative mass spectrometry study on a reconstituted human skin tissue model to identify areas affected by ionizing radiation exposure. Their results suggest that even very low doses of ionizing radiation activate cell-signaling pathways, resulting in altered protein phosphorylation and possibly altered protein function. http://phys.org/news254474652.html Chemistry Tue, 24 Apr 2012 09:00:01 EST news254474652 Using a new investigative methodology, Dartmouth researchers have found and tracked radioactive iodine in New Hampshire from the Fukushima Daiichi nuclear disaster. http://phys.org/news252581199.html Space & Earth Mon, 02 Apr 2012 10:26:48 EST news252581199 "It's not brain surgery" is a phrase often uttered to dismiss a job's difficulty, but when the task actually is removing a brain tumor, even the slightest mistake could have serious health consequences. To help surgeons in such high-pressure situations, researchers from Prof. Adam Wax's team at Duke University's Fitzpatrick Institute for Photonics and Biomedical Engineering Department have proposed a way to harness the unique optical properties of gold nanoparticles to clearly distinguish a brain tumor from the healthy, and vital, tissue that surrounds it. The team will present their findings at the Optical Society's (OSA) Annual Meeting, Frontiers in Optics (FiO) 2011, taking place in San Jose, Calif. next week. http://phys.org/news237637067.html Nanotechnology Wed, 12 Oct 2011 11:18:02 EST news237637067 Unwed mothers face poorer health at midlife than do women who have children after marriage, according to a new nationwide study, which appears in the June 2011 issue of the American Sociological Review. http://phys.org/news226215461.html Other Sciences Thu, 02 Jun 2011 06:38:01 EST news226215461 The potential health consequences of the nuclear crisis at Japan's Fukushima Daiichi plant are not equal to those caused by the disaster at Chernobyl, Japanese health officials said Tuesday http://phys.org/news224863691.html Space & Earth Tue, 17 May 2011 15:08:51 EST news224863691 The effects of a major natural disaster can linger and cause heart attacks and other health woes for years, according to a study released Sunday of New Orleans residents after Hurricane Katrina. http://phys.org/news221071421.html Medicine & Health Sun, 03 Apr 2011 17:44:04 EST news221071421 An Indiana University study found that a smoke-free air law implemented in an Indiana community did not hurt business at the off-track betting facility in that community.

The study will be published in the May 8 issue of Demography. http://phys.org/news160985299.html Medicine & Health Fri, 08 May 2009 07:09:01 EST news160985299 Americans are sleeping less than ever, according to a new National Sleep Foundation poll. Some people are losing sleep because of the economy. Some are staying up too late and getting up too early. Some have disorders such as sleep apnea. And others can't sleep because their partner snores. But the danger is the same for everybody, says Mark Opp, a professor at the University of Michigan and the senior writer of a study about sleep in this month's Nature Reviews Neuroscience. http://phys.org/news157386227.html Medicine & Health Fri, 27 Mar 2009 15:24:31 EST news157386227
