Scientists closer to finding genes that affect prostate cancer risk
Scientists believe they are on track for finding a gene, or genes, that can increase prostate cancer risk for some men - and have new evidence that a particular gene variant can reduce risk for others - putting researchers one step closer to being able to predict disease risk in individual men.

The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), has issued a task order under an existing contract to Chiron Corporation of Emeryville, CA, for the production of an investigational vaccine based on an H9N2 strain of avian influenza virus that has infected humans and has the potential to trigger a modern-day pandemic.

Other highlights in the August 18 JNCI
Other highlights in the August 18 JNCI include two studies of genes that may increase or decrease the risk of prostate cancer, an investigation of a possible predictor of neuroblastoma prognosis, a study of a new target for cancer treatments, and a study of the molecular mechanisms involved in medullary thyroid carcinoma.

Siberian forest fires partly to blame for Seattle area violating EPA ozone limit
Siberian forest fire smoke pushed Seattle's air quality past federal environmental limits on one day in 2003, and a University of Washington scientist says rapidly changing climate in northern latitudes makes it likely such fires will have greater effects all along the West Coast.
