Families, media and education crucial in preventing eating disorders
The process of educating young people on the prevention of eating disorders needs to start as early as middle-school, emphasizes Danny J. Ballard, a Texas A&M University health education professor. Ballard said that 5 to 10 million women and a million men in the United States suffer from some type of eating disorder or borderline condition that could lead to an eating disorder.

p110 delta: A key player in the allergic response
Findings from the University College London Branch of the Ludwig Institute for Cancer Research (LICR), published in this week's Nature, detail how inactivating a key signalling molecule called p110delta reduced the effect of allergies on mice.

Activity level predicts and prevents heart disease in women better than focus on weight
Although excess body weight is associated with numerous heart disease risk factors, the body mass index (BMI) appears to be a poor predictor of both existing coronary artery disease and future risk of adverse events in women. A more valuable tool may be a self-reported assessment of physical activity and functional capacity. For heart disease prevention, the tendency to focus on body mass, waist circumference, waist-hip ratio and waist-height ratio fails to address the related but more important lack of physical fitness.

NIDA sponsors frontiers in addiction research mini-convention
Frontiers in Addiction Research will bring together outstanding scientists from a wide array of research disciplines to share advances and discuss future directions in the neuroscience of drug abuse and addiction.

An unprecedented gathering on American soil of Turkish cabinet members and Turkish cultural and business leaders will converge at Stevens Institute of Technology (Hoboken, NJ) for the first Turkish-American Conference on Technology, Business and Culture:

Human brain works heavy statistics learning language
A team at the University of Rochester has found that the human brain makes much more extensive use of highly complex statistics when learning a language than scientists ever realized. The research, appearing in a recent issue of Cognitive Psychology, shows that the human brain is wired to quickly grasp certain relationships between spoken sounds even though those relationships may be so complicated they're beyond our ability to consciously comprehend.

Duke scientists overcome immune resistance in dendritic cell vaccines for cancer
Scientists have discovered why dendritic cell vaccines do not attack cancer as forcefully as expected, and they have demonstrated how to overcome this constraint by bolstering the vaccines' tumor-seeking machinery.

Migrating birds stay on track because of chemical reactions in their bodies that are influenced by the Earth's magnetic field, a UC Irvine-led team of researchers has found.

Scientists find more keys to the North Pacific Ocean's climate
Using satellite and other data, scientists have discovered that sea surface temperatures and sea level pressure in the North Pacific have undergone unusual changes over the last five years. These changes to the North Pacific Ocean climate system are different from those that dominated for the past 50-80 years, which has led scientists to conclude that there is more than one key to the climate of that region than previously thought.

Drinking a glass of red wine a day may cut a man's risk of prostate cancer in half, and the protective effect appears to be strongest against themost aggressive forms of the disease.

Hopkins to found first center for comprehensive study of epigenetics
With a $5 million, five-year federal grant, The Johns Hopkins University School of Medicine is establishing what is believed to be the first university-based research center devoted to studying epigenetics, an effort that will set the stage for learning as much about our epigenetics as the Human Genome Project taught about the sequence of building blocks that make up our genes.

LSUHSC neurosurgical team discovers novel therapy for intractable hiccups
Dr. Bryan R. Payne, and Dr. Robert Tiel, neurosurgeons at LSU Health Sciences Center in New Orleans have discovered a new approach to treating medically intractable hiccups. They implanted a Vagus Nerve Stimulator in a Texas man to stop the hiccups which have severely disrupted Shane Shafer's life following a stoke he had two years ago. This is the first reported case of its kind. When Dr. Payne activated the implant following the surgery, Shafer's hiccups stopped.

UGA named recipient of $5.6 million grant from NSF for corn improvement
Corn is by far the most important cereal grain grown in the United States, and a project at the University of Georgia that could one day lead to the development of artificial corn chromosomes has just been awarded a five-year grant by the National Science Foundation for $5.6 million.

New England forests at greater risk from air pollution
When it comes to forests, air pollution is not an equal opportunity hazard. While dirty air spreads across large areas of the New England region, it's more scattered in the southeastern part of the United States.

Janet Jackson's 'accidental' exposing of her breast was the height of fashion in the 1600s
New research from the University of Warwick reveals that Queens and prostitutes bared their breasts in the media of the 1600s to titillate the public, and that the exposure of a single breast in portraits and prints was common in portrayals of court ladies. While Janet Jackson's action of baring her right breast at the Super Bowl was considered outrageous, such exposure in 17th century media wouldn't have raised so much as an eyebrow.

New polyelectrolyte inks create fine-scale structures through direct writing
Like spiders spinning webs, researchers at the University of Illinois at Urbana-Champaign are creating complex, three-dimensional structures with micron-size features using a robotic deposition process called direct-write assembly.

Research team develops nonhuman primate model of smallpox infection
Scientists have made significant progress in developing an animal model of smallpox that closely resembles human disease, which will be necessary for testing of future vaccines and potential treatments. The study, published in this week's online early edition of Proceedings of the National Academy of Sciences, is the first to demonstrate that variola virus, the causative agent of smallpox, can produce lethal disease in monkeys.

New genetic tools provide clues to the effects of exercise and diet on obesity, diabetes
Children's National Medical Center researchers have described the molecular basis for the improvement in several CVD risk factors associated with the metabolic syndrome and the importance of skeletal muscle in governing these changes. They also found that that changes in glucose metabolism which occur in aerobic exercise trained skeletal muscle are responsible for the cardiovascular benefits of habitual exercise in individuals with impaired glucose tolerance.

Strengthening independent junior research groups in collaborative research centres
The decision made by the responsible Grants Committee on 24 and 25 May 2004 brings the total number of Collaborative Research Centres funded this year to 272, located at 61 universities, including 19 Transregional Collaborative Research Centres and 14 Transfer Units, receiving total funding of about €363 million.

Are nanobacteria alive?
After four years' work, an American team has come up with the best evidence yet that nanobacteria - a possible new life form - do actually exist. The team isolated these nanobacteria-like structures from diseased human arteries and observed them self-replicating in culture. The particles have previously been implicated in a range of human diseases. Many remain unconvinced by the research though, dismissing it as is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
