Researchers at Yale have identified multiple pathogenic "alien islands" in the genome of the A. baumannii, bacteria that has been responsible for new and highly drug-resistant infections in combat troops in the Middle East, according to a report in the March 1 issue of Genes and Development.
A national survey of commercial health plans has found that most plans provide online information regarding mental health and substance abuse but few provide clinical services such as counseling via the Internet. The nationally representative health plan survey, published in Psychiatric Services, and led by Dr. Constance Horgan at Brandeis University, is one of the first to examine the prevalence of health plan-sponsored online resources for behavioral health.
In the largest study of its kind, surgeons at Hospital for Special Surgery have determined that by modifying a classic ligament surgery, they can return more athletes, such as baseball players, to their prior level of competition. The modified surgery repairs a torn medial collateral ligament (MCL), which links and stabilizes bones of the lower and upper arm where they meet at the elbow.
Less traumatic than the classic Tommy John surgery, the modified surgery called the docking procedure, with time, is likely to become the gold standard for treating these injuries.
Researchers have used the world's thinnest material to create a new type of technology, which could be used to make super-fast electronic components and speed up the development of drugs.
Physicists at The University of Manchester and The Max-Planck Institute in Germany have created a new kind of a membrane that is only one atom thick.
It's believed this super-small structure can be used to sieve gases, make ultra-fast electronic switches and image individual molecules with unprecedented accuracy.
The future of cancer detection and treatment may be in gold nanoparticles - tiny pieces of gold so small they cannot be seen by the naked eye. The potential of gold nanoparticles has been hindered by the difficulty of making them in a stable, nontoxic form that can be injected into a patient. New research at the University of Missouri-Columbia has found that a plant extract can be used to overcome this problem, creating a new type of gold nanoparticle that is stable and nontoxic and can be administered orally or injected.
Drinking whole fat milk and eating ice cream appears to be better for women trying to become pregnant than a diet consisting of low-fat dairy products such as skimmed milk and yoghurt, according to new research published in Europe's leading reproductive medicine journal, Human Reproduction, today (28 February). 
Purdue University researchers have created a handheld sensing system its creators liken to Star Trek's "tricorder" used to analyze the chemical components of alien worlds. But the system could have down-to-earth applications, such as testing foods for dangerous bacterial contaminants including salmonella, which was recently found in a popular brand of peanut butter.
"Nanotechnology has the potential to generate enormous health benefits for the more than five billion people living in the developing world," according to Dr. Peter A. Singer, senior scientist at the McLaughlin-Rotman Centre for Global Health and Professor of Medicine at University of Toronto. "Nanotechnology might provide less-industrialized countries with powerful new tools for diagnosing and treating disease, and might increase the availability of clean water."
New information about a link between the growth of blood vessels critical to the spread of cancer and the copper in our bodies has been discovered by researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago, using a beamline at the Advanced Photon Source.
Deep red tomatoes get their rich color from lycopene, a disease-fighting antioxidant. A new study, however, suggests that a special variety of orange-colored tomatoes provide a different form of lycopene, one that our bodies may more readily use.
Researchers found that eating spaghetti covered in sauce made from these orange tomatoes, called Tangerine tomatoes, caused a noticeable boost in this form of lycopene in participants' blood.
