Death rates from the four most common cancers - lung, breast, prostate, and colorectal - continued to decline in the late 1990s according to new data from the

Host response to anthrax lethal toxin suggests some current treatment strategies are inappropriate
A comprehensive study of the effects of anthrax lethal toxin in mice by Stephen Leppla and colleagues at the National Institutes of Health demonstrated that toxin-induced death does not result from septic shock mediated by cytokine release as previously thought, but via hypoxia-induced liver failure.

Mouse study gives new view of anthrax toxin
A large-scale study of anthrax in mice has yielded new information about immune system response to anthrax bacteria, according to scientists at the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health.

Oral sodium clodronate may slow the development of symptomatic bone metastases and reduce the risk of death in men with advanced prostate cancer, according to a randomized controlled trial in the September 3 issue of the Journal of the National Cancer Institute.

Cost reductions will hasten fuel cell commercialization
The commercial viability of the fuel cell, the clean and quiet technology, is heavily dependant on cost reductions that assume greater significance as worldwide concern for rapidly depleting non-renewable fossil fuels increases.

Chicken embryo research tunes into inner ear
Purdue University biologists have learned how to control the development of stem cells in the inner ears of embryonic chickens, a discovery which could potentially improve the ability to treat human diseases that cause deafness and vertigo.

Combating corrosion could aid industrial safety
A new technique to detect localised corrosion in steel and other metals could help industry avoid major repair bills.

Mouse, stripped of a key gene, resists diabetes
An engineered mouse, already known to be immune to the weight gain ramifications of a high-calorie, high-fat diet, now seems able to resist the onset of diabetes.

New blood test uncovers individual risk for lung cancer
Scientists at the Weizmann Institute have discovered a new genetic risk factor that increases the susceptibility of smokers to lung cancer.

Abdominal fat, a contributor to heart disease risk, is related to alcohol drinking pattern
How you drink alcohol -- how often, how much, when and what kind -- can influence the risk of heart disease by affecting the accumulation of abdominal fat, a body characteristic shown to be an important risk factor for cardiovascular diseases, University at Buffalo epidemiologists have shown.

DNA repair activity may be associated with risk of lung cancer
People with reduced DNA repair activity, as determined by a blood test, appear to be at a higher risk of developing lung cancer than people with average DNA repair activity, according to a study in the September 3 issue of the Journal of the National Cancer Institute. The findings suggest a genetic predisposition to lung cancer in some individuals and may explain why only a fraction of smokers develop the disease.
