It has often been claimed that psychological stress is an important cause of heart disease, but a study in this week’s BMJ shows that previous research may have been misleading.
Researchers measured self-assessed stress amongst middle-aged Scottish men working in and around Glasgow in the early 1970s. These men were then followed for more than twenty years to see whether or not they developed heart disease. Several different measures of heart disease were used.
Men who thought they
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
Scientists at the University of Ulster have unveiled a monitoring system that can ensure transplant organs arrive in pristine condition for the life-saving surgery.
They have developed tiny sensors which are inserted in the organs, and which monitor if there has been any deterioration in the organs’ condition since being removed from the donor.
The sensors are flexible micro-electrodes based on pioneering nanotechnology, which are implanted in the donor organ.
The electrodes mo
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:
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.

Journal of Biology ( http://www.jbiol.com ) is a new international journal, published by BioMed Central, which provides immediate open access to research articles of exceptional interest. It will only publish research articles of the highest standard, similar to those published by Nature, Science or Cell. While these journals restrict access to only those who pay for a subscription, all research articles published in Journal of Biology will be permanently
