Activity Generates New Nerve Cells For Old Mice – Study Supports Link Between Active Life And Lower Risk Of Neurodegenerative Disease

Active older people seem to have a lower risk of certain neurological disorders such as Alzheimer`s disease. A study published May 22 in the on-line edition of the Annals of Neurology, the research publication of the American Neurological Association, demonstrates how this increased activity might protect the brain.

Breastfeeding might protect against cot death, suggests research in the Archives of Disease in Childhood.

The researchers surveyed the parents of 244 babies who had died of sudden infant death syndrome (SIDS) and 869 babies still alive and well to find out how they had been fed. The study was conducted between 1992 and 1995. Over 80 per cent of the SIDS baby parents and almost three quarters of the comparison group responded.

During the study period breast feeding among the c

Further cases of Creutzfeldt-Jakob (CJD) disease could arise as a result of human growth hormone treatment, even after low doses, suggests research in the Journal of Neurology Neurosurgery and Psychiatry.

Dutch researchers report on the case of a man who developed CJD 38 years after receiving human derived growth hormone.

A 47 year old man was given only a low dose as part of a diagnostic procedure, rather than being given full treatment, which may explain why the incubation period

Gold prospectors may one day rely on lowly bacteria to point them to deposits of the precious metal. Researchers have discovered that gold-laden soil often contains an abundance of spores belonging to a certain bacterium. The affinity humans have for gold aside, the ore in its soluble form is actually highly toxic to most living things. The common bacterium Bacillus cereus , however, possesses a unique resistance to the metal, allowing it to survive in a relatively vacant environmental niche:

New evidence suggests that hundreds of unseen dwarf galaxies made of dark matter encircle our Milky Way and other large, visible galaxies. Scientists believe that 80 to 90 percent of the universe must be made of this as-yet-undetected matter to account for the observed structure of the universe. According to Einstein, such large concentrations of matter should warp the surrounding space and bend light in much the same way that glass lenses do. With that in mind, astrophysicists at the University of C

With the help of biologists and in a radical reversal of roles, the environment could exploit free trade. But with the World Trade Organisation`s legitimacy being challenged as never before, this opportunity is at risk.

“In the prevailing climate, trade protectionism gets equated with environmental protection, free trade with freedom to plunder”, says Dr Douglas Yu at the University of East Anglia`s School of Biological Sciences. “But the WTO could actually drive fundamental environmental re
