Kursk sub's risk of leaking radiation minimized by built-in protections, health physicist says
Disagreeing with recent comments made by a Russian environmentalist on the possibility of radiation leaking from the sunken Kursk submarine, a health physicist states that nuclear sub design has several built-in defenses that minimizes such risks.

New crop protection method could save US farmers billions
Naturally occuring microorganisms could be used to control 'scab, ' a fungal disease that has cost US farmers over $3 billion in the last 10 years, researchers reported here today at the 220th national meeting of the American Chemical Society.

Balanced diet lowers homocysteine, reducing risk of heart disease
Researchers at Johns Hopkins have found yet another reason to eat a well-balanced diet low in fats and rich in fruits and vegetables: It lowers blood levels of homocysteine, thereby reducing the risk of heart disease.

Study launched to test public access defibrillation
Can community volunteers be as effectively trained as emergency medical personnel in the use of automatic external defibrillators, devices that shock a stopped heart back into beating?

Molecular architects create new cancer preventives
Researchers at Johns Hopkins have developed a modified form of vitamin D and determined that it helps delay the onset and reduce the number of skin cancers in lab mice.

Repairing brain damage from stroke may be possible with brain cell transplants
A new technique of transplanting laboratory- grown neuronal cells into the brains of stroke patients is safe and well-tolerated by patients, according to a study in the August 22 issue of Neurology, the scientific journal of the American Academy of Neurology.

Jefferson scientists hope to perfect gene therapy without viruses
Researchers at Jefferson Medical College have developed a gene therapy system that sidesteps viruses - and they hope, some of the inherent problems with their use.

Molecular-scale roughness identified as factor in bacteria's ability to stick to surfaces
Using an atomic force microscope to probe the surface of glass, mica, and quartz at the molecular level, Penn State engineers have, for the first time, identified the bacteria- sized peaks and valleys in this tiny terrain as an important factor in microbes's ability to adhere to some of these materials is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
