women's memory is better than men's.



A new study has confirmed what many men already knew:women's memory is better than men's.

In the University of London study, which included 9,600 people in their 50s, it was found that middle-aged women have better memories than men. In the first experiment, volunteers test listened to 10 words and were given two minutes to recall as many as possible. The second test required them to list the same 10 words about five minutes later.

Females scored almost 5% more than men in the first test and nearly 8% more in the second. In another test, which involved naming as many animals as possible in one minute, men and women had identical scores. Non-smokers, including ex-smokers, also outscored smokers in the first of the 'word recall' tests.

Humans 'could regrow body parts'





LONDON: The fabled human spare parts kit may someday become a reality,thanks to scientists who claim to have discovered a gene which could allow regrowing of damaged body parts. An international team, led by The Wistar Institute in Philadelphia, has found that the p21 gene could block the healing power still enjoyed by some creatures like amphibians, but lost through evolution to all other animals. By turning off p21, the process can be miraculously switched back on. In their research, the scientists found that mice lacking the p21 gene gain the ability to regenerate lost or damaged tissue. Unlike typical mammals, which heal wounds by forming a scar, these animals begin by forming a blastema, a structure associated with rapid cell growth. According to them, the loss of p21 causes the cells of these mice to behave more like regenerating embryonic stem cells rather than adult mammalian cells. This means they act as if they creating rather thane mending the body. They turned off the gene in mice which had damaged ears and they regrew them. While they say it is early days, there is nothing theoretically different about applying the same process to humans, 'The Daily Telegraph' reported.

PAINKILLER KILLS HEARING-----


Loud music or noise isn’t the only thing that can damage your hearing. A new study in men hints that popping over-the-counter painkillers regularly can also lead to hearing loss, especially in younger men....
