Consumption of green tea may help prevent cancer, suggest epidemiological studies conducted by researchers at the University of Toledo, Ohio, USA. Green tea contains chemicals called cathechins, including epigallo-cathechin-3 gallate (EGCG). EGCG inhibits urokinase (uPA), an enzyme which promotes cancerous growth. Researchers say that cancers need enzymes like uPA to …
Women can help prevent deterioration of their child's intelligence in later years by avoiding toxins and leading a healthy life during pregnancy.

If a comet merely ten-thousandth the size of Hale-Bopp strikes the Earth, it would create an explosion ten times as powerful as all the nuclear weapons in existence at the height of the Cold War, according to a supercomputer simulation. David Crawford of Sandia National Laboratories, Livermore, California, has modelled …
Plans are being finalised for the world's largest radio telescope by astronomers from India, Australia, Canada and three other countries. The telescope
exposure to nuclear tests conducted in the early '90s at the Nevada test site near Las Vegas may have caused 10,000 to 75,000 thyroid cancers among Americans, 70 per cent of which have not yet been detected, states a recently released report of the usa -based National Cancer Institute. "There …
