Washington, Apr 7 : It might not come as a surprise to most wives, mothers and female workers, but a new study has found that women cope better under strain than men.

What''s more, people of either sex with certain genetic advantages handle stress nicely.

Some people appear to be resilient to difficult conditions, whereas others react adversely to such challenges, incurring a range of physical and mental disorders. Much research has shown that the way in which the brain and body adapt to acute and chronic stress are critical for physical and mental health.

Washington, April 7 : Kids lacking an ability to regulate their behaviour, or to delay gratification in exchange for a larger reward, are more likely to become overweight by their pre-teen years, according to a study.

"Obesity in childhood and adolescence appears to track into adulthood, increasing the risk of developing cardiovascular disease, diabetes mellitus and certain cancers in adulthood," the authors write as background information in one of the articles.

Washington, April 7: Children and adolescents can be prevented from consuming an average of 235 excess calories per day by replacing consumption of sugar-sweetened beverages (SSBs) with water, according to a study.

Such a replacement may prove very helpful in dealing with childhood overweight and obesity, and address dental cavities and other health problems associated with added sugar, say the study’s authors.

This lifestyle change will have no detrimental effects on nutrition, they add.

Washington, April 7: Mario Capecchi, Nobel Laureate for Medicine in 2007, has announced the invention of a technique to reveal the stem cells camouflaged in the pancreas.

The achievement made in collaboration with Eugenio Sangiorgi, a researcher from the Catholic University of Rome, is important because, to date, scientists don''t have a method to distinguish a priori between a stem cell and any other cell in the same tissue.

“We can only infer that a cell really is a stem cell by observing its behaviour," says Sangiorgi.

Singapore - A second Singapore woman has gone into a coma after suffering acute food poisoning a day after the first victim's death, media reports said Tuesday.

Washington, Apr 7 : Science is trying its level best to improve people''s sex lives -and the latest offering from scientists is a spray which helps men last six times longer in bed.

Developed by British doctors, the treatment - used five minutes before sex - can extend love-making time from seconds to almost four minutes.

The study has been published in the April issue of BJU International.

To reach the conclusion, three hundred men with clinically diagnosed lifelong premature ejaculation (PE) from 31 centres in the UK, Czech Republic, Hungary and Poland, were randomised into two groups.
