This is demonstrated in a study published in the new issue of the scientific journal New Iraqi Journal of...
What is really happening to the Greenland icecap?
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.

A framework for such research was defined at a recent...

Fibromyalgia can no longer be called the 'invisible' syndrome

What's the role of Kupffer cells in non-alcoholic steatohepatitis?
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...

Flu shot protects kids -- even during years with a bad vaccine match
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.
Grandparents a safe source of childcare
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...
Memo to ER docs: Send young victims of violence for 1-on-1 counseling
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.

Microsoft unveils 60 million dlr investment in SKorea
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.
Minor shift in vaccine schedule has potential to reduce infant illness, death
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.
Sarcospan, a little protein for a big problem
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.
Study is first to link viewing of sexual content on TV to subsequent teen pregnancy
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.
West Nile's North American spread described
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.

Detecting tiny twists with a nanomachine
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.
Genetic test can reveal a painful truth
Wanda Stutsman was 32 years old and seven months pregnant when she began her first round of chemotherapy.
Human genes sing different tunes in different tissues
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.
