Washington, March 1 : Scientists have discovered how changes to a frog's immune system may be the key to beating a viral infection which is devastating frog populations across the UK.
Communities of common frogs (Rana temporaria) are being struck down by a foreign virus which is estimated to be killing tens of thousands of frogs in the UK each year.
When it strikes garden ponds, the surrounding lawn becomes strewn with dead frogs, some with skin ulcers so severe they reduce limbs to stumps, others with internal bleeding.
Washington, Mar 1 : As Barbie gears up to celebrate her 50th birthday, an American researcher weighs in on what the doll with hourglass curves did to boost her health.

According to Cindy Haines, M. D., a family doctor and clinical assistant professor of family and community medicine at Saint Louis University, she's a poster child for what happens when you take good care of yourself.
Washington, March 1 : Healthy elderly patients with severe to profound hearing loss can undergo a surgical procedure to receive cochlear implants with minimal risk, says an Indian-origin researcher.
"Due to concerns about the effects of general anesthesia, many elderly people with hearing loss are not receiving the implants which can significantly improve their hearing and quality of life," says Dr. Anil Lalwani, Mendik Foundation Professor of Otolaryngology and Chairman of the Department of Otolaryngology at NYU School of Medicine and a study co-author.
Washington, March 1 : American spine surgeons say that artificial disc replacement often works better than spinal fusion surgery.
Both procedures are performed on people whose discs in the neck get damaged.
Experts at Washington University School of Medicine in St. Louis and other U. S. centres found that patients who received an artificial disc lost less motion in the neck and recovered faster than those who had a disc removed and the bones of the spine fused.
Recent study revealed that exercise can affect hippocampus size and memory in humans. Earlier studies have already proven this phenomenon in animal models. A curved structure deep inside the brain is known as hippocampus. It is a key player in spatial navigation and other types of relational memory.
Research led by Art Kramer of the University of Illinois and Kirk Erickson of the University of Pittsburgh, analyzed data collected from 165 adults, ages 59 to 81.
Recent study revealed how caffeine can offer protection against skin cancer. Research team led by Dr. Paul Nghiem, an associate professor of dermatology at the University of Washington in Seattle studied the caffeine's effect on human skin cells in a laboratory that had been exposed to ultraviolet radiation.
Research team found that caffeine interrupted a protein called ATR-Chk1 in cells damaged by UV rays. This led the damaged cell to self destruct. Caffeine had no effect on the healthy cells.
