Scientists find bird flu antibody
Posted by: Derya on: May 30, 2007
Scientists working in Switzerland, Vietnam and the United States say they have isolated antibodies that they hope could offer protection against several different strains of the virus simultaneously. Antibodies are used by our immune system to neutralise bacteria and viruses – in this case, the scientists have isolated antibodies that bird flu survivors in Vietnam [...]

People looking to shed body fat might want to follow their workouts with a few capsules of fish oil, if preliminary research is correct. In a study of overweight adults, Australian researchers found that a combination of exercise and fish oil supplements was effective at reducing body fat and improving cholesterol levels and blood vessel [...]
Researchers restore the sight of blind mice using gene therapy
Posted by: Derya on: May 22, 2007
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. Writing online in today’s (May 21) edition of Nature Medicine, scientists describe how they used a harmless virus to deliver corrective genes to mice [...]
Scientists succeed in hair follicle regeneration in an animal model
Posted by: Derya on: May 20, 2007
Researchers at the University of Pennsylvania School of Medicine have found that hair follicles in adult mice regenerate by re-awakening genes once active only in developing embryos. These findings provide unequivocal evidence for the first time that, like other animals such as newts and salamanders, mammals have the power to regenerate. These findings are published [...]

Over 30% of our genes are under the control of small molecules called microRNAs. They prevent specific genes from being turned into protein and regulate many crucial processes like cell division and development, but how they do so has remained unclear. Now researchers from the European Molecular Biology Laboratory (EMBL) have developed a new method [...]

Hugh Herr has spent the past decade building better prosthetic limbs, but this week was the first time he was able to demonstrate one of his own devices. A double amputee since he was in a rock-climbing accident in 1982, Herr unveiled his latest design at an MIT conference on Wednesday: a novel prosthesis modeled [...]

Imagine taking a vitamin for longevity! Not yet, but a Dartmouth discovery that a cousin of niacin prolongs lifespan in yeast brings the tantalizing possibility a step closer. The research, reported in the May 4 issue of Cell, shows how a new vitamin extends lifespan in yeast cells, much like calorie restriction does in animals. [...]
