Researchers from Louisiana State University are now blaming human stem cells for causing obesity in people. A new study found that infection with a virus linked to human obesity increases the fat-cell production thus making them fatter.

A term called "infectobesity" can now be used by people to blame for the growing problem of obesity. The research finds that when human stem cells were exposed to a common virus they not only turned into fat cells but also stored fat

The U.S. Food and Drug Administration (FDA) has asked a Seattle-based company to halt its gene therapy study after reports that a patient has died.

The FDA said it was investigating if the gene therapy played any role in the death of the patient, which occurred Tuesday

Scientists announce a newly produced vaccine against the H5N1 strain of bird flu that has protected mice, using a genetic engineering technique that can be easily scaled up for stockpiling the drug to prepare for a pandemic.

In a report published Thursday by a British medical journal The Lancet, researchers say the experimental vaccine uses a common cold virus or adenovirus engineered with bird flu DNA, to stimulate the body's defenses
