The risk of depression is greater among Iraqi soldiers who took part in the Gulf War than among civilians. Surprisingly, on the other hand, neither of these groups showed any signs of post-traumatic stress ten years after that war-­with the exception of those Iraqis who have left Iraq. This is demonstrated in a study published in the new issue of the scientific journal New Iraqi Journal of...

The Greenland ice cap has been a focal point of recent climate change research because it is much more exposed to immediate global warming than the larger Antarctic ice sheet. Yet while the southern Greenland ice cap has been melting, it is still not clear how much this is contributing to rising sea levels, and much further research is needed. A framework for such research was defined at a recent...

Why are the number of students studying soil science as a major declining across the United States? Mary Collins, University of Florida, Gainesville, writes about this in an article published in the 2008 Journal of Natural Resources and Life Sciences Education.

Using single photon emission computed tomography (SPECT), researchers in France were able to detect functional abnormalities in certain regions in the brains of patients diagnosed with fibromyalgia, reinforcing the idea that symptoms of the disorder are related to a dysfunction in those parts of the brain where pain is processed.

Nonalcoholic steatohepatitis (NASH) is a disorder characterized by hepatic steatosis, inflammation and fibrosis with a risk of developing cirrhosis and hepatocellular carcinoma (HCC). The progression from simple steatosis to cirrhosis has been attributed to inflammatory cytokines such as tumor necrosis factor alpha (TNF-), oxidative stress and endotoxin, in combination with fatty...

(AP) -- Ruben Navarro loved horror movies. He watched the "Nightmare on Elm Street" and "Friday the 13th" series with his mother, Rosa, and liked to visit Knott's Berry Farm when it was transformed every October to "Knott's Scary Farm."

Most people diet to trim waistlines a belt notch or two. Bob Cavanaugh and other members of the US-based Calorie Restriction Society are more ambitious.

The fight against climate warming has an unexpected ally in mushrooms growing in dry spruce forests covering Alaska, Canada, Scandinavia and other northern regions, a new UC Irvine study finds.

Children who receive all recommended flu vaccine appear to be less likely to catch the respiratory virus that the CDC estimates hospitalizes 20,000 children every year.

For working parents, having grandparents as caregivers can cut the risk of childhood injury roughly in half, according to a new study by researchers from the Johns Hopkins Bloomberg School of Public Health. Compared to organized daycare or care by the mother or other relatives, having a grandmother watch a child was associated with a decreased risk of injury for the child. The study is among the...

A study of 113 children and teens physically victimized by peers concludes that one-on-one mentoring about how to safely avoid conflict and diffuse threats makes them far less likely to become victims again if guidance is initiated in the immediate aftermath of the attack.

(AP) -- Beneath the tourist gondolas in the remains of a great Aztec lake lives a creature that resembles a monster - and a Muppet - with its slimy tail, plumage-like gills and mouth that curls into an odd smile.

Microsoft chief Steve Ballmer on Monday unveiled a plan to invest 60 million dollars in South Korea's software industry as part of the US giant's drive to strengthen its presence in the country.

A new study by researchers at Wake Forest University School of Medicine and Vanderbilt University suggests that protecting infants from a common, highly contagious and even deadly disease may be as easy as administering a routine vaccine two weeks earlier than it is typically given.

The overlooked and undervalued protein, sarcospan, just got its moment in the spotlight. Peter et al. now show that adding it to muscle cells might ameliorate the most severe form of muscular dystrophy.

Adolescents who have high levels of exposure to television programs that contain sexual content are twice as likely to be involved in a pregnancy over the following three years as their peers who watch few such shows, according to a new RAND Corporation study.

The rapid spread of West Nile virus in North America over the past decade is likely to have long-lasting ecological consequences throughout the continent, according to an article in the November issue of BioScience. The mosquito-borne virus, which was little known before its emergence in New York in 1999, has since been found in all 48 contiguous states.

MySpace and Auditude have rolled out an innovative solution to the problem of people posting pirated television show snippets on the Internet.

Adding an artificial tumor-specific receptor to immune system cells called T-lymphocytes that target a particular virus extended and improved the cells' ability to fight a form of childhood cancer called neuroblastoma, said researchers form Baylor College of Medicine and Texas Children's Hospital in a report that appears online today in the journal Nature Medicine.

(AP) -- Nelson Mdlovu strides out of the small clinic with a spring in his step and a smile on his lips just minutes after being circumcised.

At Children's Hospital of Philadelphia, surgeon Howard Snyder says he and his colleagues repair the genitalia of roughly 300 baby boys every year - about double what they did when he started his practice 30 years ago.

Researchers at Boston University working with collaborators in Germany, France and Korea have developed a nanoscale torsion resonator that measures miniscule amounts of twisting or torque in a metallic nanowire. This device, the size of a speck of dust, might enable measurements of the untwisting of DNA and have applications in spintronics, fundamental physics, chemistry and biology.

Wanda Stutsman was 32 years old and seven months pregnant when she began her first round of chemotherapy.

Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA. Now, an MIT team has shown that this phenomenon, known as alternative splicing, is both far more prevalent and varies more between tissues than was previously believed.
