University of Florida researchers used gene therapy to restore sight in mice with a form of hereditary blindness, a finding that has bearing on many of the most common blinding diseases.

A simple method of flash-heating breast milk infected with HIV successfully inactivated the free-floating virus, according to a new study led by researchers at the Berkeley and Davis campuses of the University of California.

Researchers at Harvard University and Princeton University have made a crucial step toward building biological computers, tiny implantable devices that can monitor the activities and characteristics of human cells. The information provided by these "molecular doctors," constructed entirely of DNA, RNA, and proteins, could eventually revolutionize medicine by directing therapies only to diseased cells or tissues.

Ultraviolet rays can be harmful to our skin and pave the way to the onset of skin cancers. VIB researchers connected to Ghent University have demonstrated that the caspase-14 protein - whose function has been unknown up to now - not only plays a role in maintaining the balance of moisture in the skin but also offers protection against UVB rays. Future strategies that increase the production of caspase-14 will open new possibilities for fortifying the skin as a barrier against all kinds of stress.

A team of researchers has documented major changes in the behavior, ecology, and geographic range of the northern fur seal over the past 1,500 years using a combination of techniques from archaeology, biochemistry, and ecology. Among their findings is evidence of reproductive behavior in the past that is not seen in modern populations of northern fur seals.

RICHMOND, Va. (May 21, 2007) – The use of peginterferon alone, or in combination with ribavirin, points to a cure for hepatitis C, the leading cause of cirrhosis, liver cancer and the need for liver transplant, a Virginia Commonwealth University researcher said today.

Investigators at St. Jude Children's Research Hospital have gained some of the first major insights into how certain genes known to prevent cancer also guide the normal development of the nervous system before birth and during infancy by repairing DNA damage.

Community preparedness for a bioterrorism attack or influenza outbreak has been the focus of much interest and effort in recent years. Now, public health experts at NewYork-Presbyterian Hospital/Weill Cornell Medical Center have developed a strategy for how hospitals can most efficiently inoculate their own staff with minimal disruption to patient care.

The scientists could show that Parkin prevents the induction of neuronal cell death. As reported in the "Journal of Neuroscience", the protein activates a survival mechanism which had been known for its prominent role in immune response.

An outbreak of drug-resistant wound infections among soldiers in Iraq likely came from the hospitals where they were treated, not the battlefield, according to a new study in the June 15 issue of Clinical Infectious Diseases, currently available online.
