A new study may help explain why women are more prone to sports injuries than men, as previous research has suggested.

Winds in Pacific climate cycle can foretell Gulf of Mexico hurricanes
A short-term climate cycle that builds in the Indian Ocean and moves eastward through the equatorial Pacific Ocean is a key factor in the formation of hurricanes and tropical storms over the Gulf of Mexico and the western Caribbean Sea, University of Washington researchers have found.

Walking trails boost exercise, improve health at low cost
Exercise is a well known but little used path to better health, so how can communities get more arms and legs pumping before too many hearts stop pumping?

American Thoracic Society news tips for March 2000
News tips from the American Thoracic Society journals for March 2000 feature briefs on research directed at a treatment that prevented all auto accidents for high risk sleep apnea patients over two years; the development of the first biochemical marker for acute lung injury; and a study showing X-ray screening for tuberculosis is the most cost effective disease prevention method for immigrants from high-risk countries.

Public walking trails may increase community fitness levels
When communities build walking trails, new evidence suggests that people may exercise more.

Researchers discover retinal stem cells in adult mammals
When it comes to stem cells, it appears the eyes have it -- researchers at the University of Toronto and the Hospital for Sick Children (HSC) have identified retinal stem cells in the adult mammalian eye, opening the door for retinal regeneration as a possible cure for damaged or diseased eyes.
