Micro-organisms help protect drinking water from MTBE contamination
Micro-organisms that live at the bottom of lakes and streams may offer a solution to the problem of drinking water contamination from the gasoline additive MTBE, according to a new study by government scientists.

A sharper look at the brain
Thanks to a dramatic improvement in imaging techniques, achieved by a research group from the Max Planck Institute for Biological Cybernetics and Eberhard Karl University (both in Tübingen, Germany), it is now possible to generate high- resolution pictures of the monkey brain in a quality never seen before (Nature Neuroscience, Vol.

3-D view of moon poles may show sites for ice
The hidden poles of the moon have been revealed by Cornell University and Jet Propulsion Laboratory researchers working with the radar antennas of NASA's Deep Space Network at Goldstone, Calif.

Researchers pinpoint thinking pattern of chronic self-doubters

Berkeley lab researchers explain the striking effects of nitrogen in a semiconductor alloy
The search for more efficient solar cells recently has focused on an unexplained benefit derived from incorporating small amounts of nitrogen into the semiconductor alloy gallium indium arsenide.

Report in Science on x-ray crystal structure of matrix Metalloproteinase-2 (MMP-2)
BioStratum announces that the three-dimensional structure of the matrix metalloproteinase-2 (MMP-2), a key molecular target for a number of anti-cancer drug candidates currently in clinical development is reported in the June 4, 1999 issue of Science. Knowing the crystal structure of this protein will enable the design of more effective inhibitors to the protein which will help combat the spread of cancer.

Technology brings engine oil analysis on board
Technology developed at Pacific Northwest National Laboratory with LRC Northwest, of Richland, Wash., will provide railroad companies with valuable information about a train engine's condition without having to take the locomotive out of service.

Scientists prepare New York City for future climate change

Dehydration makes exercise-induced asthma worse, study by UB researchers finds
If athletes from elite to novice needed yet another reason to drink plenty of fluids during exercise, a new study by University at Buffalo exercise scientists provides it.

Men at highest risk least likely to comply with post-heart-attack exercise program, UB study finds
Men recovering from a heart attack who are at the highest risk of a second attack and thus would benefit most from conscientious participation in an exercise program are the least likely to do so, a University at Buffalo study has found.

Ratio of doctors to patients is good predictor of hospital death rates in England
One of the key determinants of hospital death rates is the number of hospital doctors per bed and the number of general practitioners per head of population in the localities from which admissions were drawn, say researchers in this week's BMJ.

Standardized treatment protocol reduces deaths from malnutrition by 47%
Malnutrition is responsible, at least in part, for nearly 6 million deaths in children under five each year.
