Novel airborne germ-killing oral spray effective in fighting colds and flu

Posted: 09 Sep 2012 12:04 PM PDT

A new oral antiseptic spray is effective in killing 99.9 percent of infectious airborne germs that cause colds and the flu.

New potential targets discovered for treating squamous cell lung cancers

Posted: 09 Sep 2012 12:04 PM PDT

A new study holds out hope that people with the second most common type of lung cancer may one day benefit from targeted therapies that have transformed treatments for other lung cancer patients. Scientists have identified many potential targets based on the large number and variety of DNA alterations they discovered in most tumors.

Nano-velcro clasps heavy metal molecules in its grips

Posted: 09 Sep 2012 12:03 PM PDT

Researchers have devised a simple, system based on nanoparticles, to detect mercury as well as others pollutants. This technology makes it possible to easily and inexpensively test for these substances in water and, importantly, also in the fish that we eat.

Protecting genes, one molecule at a time

Posted: 09 Sep 2012 12:03 PM PDT

Scientists have shown at an unprecedented level of detail how cells prioritize the repair of genes containing potentially dangerous damage. The research studied the action of individual molecules in order to understand how cellular repair pathways are triggered.

Why an AIDS vaccine has been so difficult to develop

Posted: 09 Sep 2012 12:03 PM PDT

New research explains a decades-old mystery as to why slightly weakened versions of the monkey AIDS virus were able to prevent subsequent infection with the fully virulent strain, but were too risky for human use, and why severely compromised or completely inactivated versions of the virus were not effective at all.

First evidence for a genetic cause for Barrett's esophagus

Posted: 09 Sep 2012 12:03 PM PDT

Genetic variations that are linked with the onset of Barrett's esophagus, a pre-cancerous condition of the lower end of the gullet, have been identified for the first time. The discovery of variations in regions on two chromosomes makes it possible to develop screening tests for people at high risk of developing the disease.

Genetic clues to the causes of primary biliary cirrhosis: Researchers find new risk regions associated with primary biliary cirrhosis

Posted: 09 Sep 2012 12:02 PM PDT

Researchers have used a new technology to uncover three genetic regions associated with primary biliary cirrhosis (PBC), the most common autoimmune liver disease. With this technology, scientists will now be able to survey more thoroughly regions of the genome known to underlie other autoimmune diseases to discover if they play a role also in PBC susceptibility.

Cost-effectiveness of HIV testing in drug abuse treatment programs demonstrated

Posted: 09 Sep 2012 12:02 PM PDT

Less than half of community-based substance abuse treatment programs in the United States currently make HIV testing available on-site or through referral. A new study shows the cost-effectiveness of integrating on-site rapid HIV testing into drug treatment programs.
