Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

...n of a variety of species by reducing their normal food consumption by 30 to 40 percent - a diet known as calorie restriction. Through this research, scientists identified Sir2 as a key contributor to life extension. Without Sir2, for example, fruit flies see none of the benefits from either calorie rest...

Gene key to taste bud development identified

...at cover the surface the tongue and help to direct food to the back of the mouth. The new findings could lead to a better understanding of developmental disorders of the gut caused by mutations in the human SOX2 gene, Hogan said. For example, babies with such mutations can develop a tracheoesophageal fi...

Fake pesticides threaten food safety

...d in the EU could be fake, potentially endangering food safety and human health, writes Cath O'Driscoll in Chemistry & Industry, the magazine of the SCI. These counterfeits range from sophisticated copies of patented products to low-quality fakes with little or no resemblance to the original. And it ...

Theory of oscillations may explain biological mysteries

...action between two weakly competing consumers of a food resource can be transformed by the arrival of a third competitor to provide unpredictable opportunities for the newcomer to invade. Vandermeer holds out hopes that the study of oscillations in biological populations will lead to insights into complex...

Ghengis Khan wonder berry could conquer heart disease

... lining of blood vessels. Consuming the berries in food or drinks is expected to prevent the arteries from clogging up. Arumughan is confident that this technology had great potential, saying "No previous report has shown efficiency matching ours". Arumughan's team have unlocked the nutrients by applyi...

'Empty nester' parent birds use recruitment calls to extend offspring care

They can tolerate a wide range of water temperatures, salinity and pH levels. Carp can also survive and breed in polluted, poorly o...

Study illuminates how the plague bacteria causes disease
