Lab made cornea offers new hope for restored vision
(Aug 26, 2010)

Corneas made in the laboratory have markedly improved the sight of 10 Swedish patients with significant vision loss. Produced entirely from synthetic collagen, the implants offer the tantalizing possibility for a replacement to human donor tissues. The custom-made corneas work by prompting regeneration of the nerves and cells in the eye.

Green leafy veg 'may cut diabetes risk'
(Aug 21, 2010)

A diet rich in green leafy vegetables may reduce the risk of developing diabetes, UK research says. In an analysis of six studies into fruit and vegetable intake, only food including spinach and cabbage was found to have a significant positive effect. A portion and a half a day was found to cut type 2 diabetes risk by 14%, the British Medical Journal (BMJ) reports.

Human brains have 'Life of Brian' mechanism
(Aug 7, 2010)

Neurologists have discovered what might be described as a "Life of Brian" brain mechanism that encourages us to look on the bright side of life – even when confronted by thoughts of mortality. Shihui Han of Peking University, China, found activity in brain regions that normally deal with negative emotions and self-awareness are dampened when we process ideas about death.

One lie-in 'not enough to counter sleep loss'
(Aug 1, 2010)

A lie-in at the weekend does not counter ill-effects of lack of sleep during the week, a study suggests. In tests on 159 adults, US researchers found that a 10-hour "recovery" snooze was not sufficient to make up for a few nights of four hours of sleep. Participants still scored poorly in measures of attention span and reaction times, the journal Sleep reported.

Aubrey de Grey: We don't have to get sick as we get older
(Aug 1, 2010)

If we can stop the physical deterioration that comes with age, molecular biologist Aubrey de Grey sees no reason why human beings shouldn't live to be 1,000. De Grey studied computer science at Cambridge University, but became interested in the problem of ageing more than a decade ago and is the co-founder of the SENS (Strategies for Engineered Negligible Senescence) Foundation, a non-profit organization based in the US.

Vaccine patch may replace needles
(Jul 19, 2010)

A vaccine patch could cut out the need for painful needles and boost the effectiveness of immunization against diseases like flu, say US researchers. The patch has hundreds of microscopic needles which dissolve into the skin. Tests in mice show the technology may even produce a better immune response than a conventional jab.

Live long and proper: Genetic factors associated with increased longevity identified
(Jul 4, 2010)

New research suggests that an important indicator of your probable life span may be your genes. Scientists have identified unique genetic signatures strongly associated with a long and healthy life, findings that could help to further the understanding of how certain genes may offer protection from common age-related diseases like cancer, dementia, and cardiovascular disease.
