How Leptospirosis Survives In Water[May. 4th 2008][Vietnam]Leptospirosis is a serious but neglected emerging disease that infects humans through contaminated water. It is a major public health problem in South East Asia and South America, with over 500,000 severe cases every year. Between 5% and 20% of these cases are fatal.
More ... Dentist Discovers A New Biological Clock[Apr. 5th 2008]Our biological rhythm controls many metabolic functions and is based on the circadian rhythm, which is a roughly 24-hour cycle that is important in determining sleeping and feeding patterns, cell regeneration, and other biological processes in mammals.

- Eco-Experts Call for Clear Climate Concepts for Organic Farming
All consumers and experts would agree that, whenever a person eats organic products, they are also doing something for the environment. But does an organic apple from Argentina protect the climate more or better than a conventional apple from a nearby orchard? This seems to be an area, in which the organic sector still has some catching up to do, if one is to believe the experts that came together last Thursday to discuss issues affecting the organic sector.
Gene Plays Protective Role In MS[Dec. 10th 2007][London]LONDON, December 10 /PRNewswire/ --
- New research announced this week has found an association between certain genes and the severity of multiple sclerosis (MS).
The results of the study by Prof George Ebers, Chair of Clinical Neurology at the Wellcome Trust Centre for Human Genetics, will be published in the journal Proceedings of the National Academy of Sciences and represent a step forward in the understanding of the role of genetics in MS.
The study involved comparing genes from people with severe MS who used wheelchairs within five years of being diagnosed and people who had no disability 20 years after diagnosis.
HD 113766 Is 'Just Right' For Building Another Earth[Oct. 3rd 2007]An Earth-like planet is likely forming 424 light-years away in a star system called HD 113766, say astronomers using NASA's Spitzer Space Telescope.
Scientists have discovered a huge belt of warm dust - enough to build a Mars-size planet or larger - swirling around a distant star that is just slightly more massive than our sun. The dust belt, which they suspect is clumping together into planets, is located in the middle of the system's terrestrial habitable zone. This is the region around a star where liquid water could exist on any rocky planets that might form. Earth is located in the middle of our sun's terrestrial habitable zone.
At approximately 10 million years old, the star is also at just the right age for forming rocky planets.
Genetic Link To PMS[Oct. 2nd 2007][Syria]The first significant genetic finding in premenstrual dysphoric disorder (PMDD) has now been reported. PMDD is a very severe form of the more commonly known premenstrual syndrome, or PMS.
PMDD is heritable, affects 5-8% of women, and is associated with severe emotional and physical problems, such as irritability, marked depressed mood, anger, headaches, weight gain and more, to such an extent that quality of life is seriously impacted.
Previously, researchers have shown that women with PMDD have an abnormal response to normal hormone levels and, thus, are differentially sensitive to their own hormone changes.
