Environmentally Safer Catalyst Makes More Hydrogen
Engineers have developed a chemical catalyst that increases hydrogen
production without using a toxic metal common to other catalysts. Though
the new catalyst is still in the early stages of testing, it could
represent an important step toward using the nation's coal supply to power
alternative fuel vehicles and equipment. (Embargo expired on 16-Mar-2005

Compound May Help Prevent Diabetes in Fast-Food Fans
A new finding could soon benefit people who regularly eat fast-foods
that are high in fat. Chemists report they have identified a form of
soluble cellulose that, if added to high-fat food, appears to slow fat
absorption to a healthier rate and reduce the likelihood of developing
insulin resistance, a precursor to type 2 diabetes. (Embargo expired on

Complex Behaviors Hard-Wired in Primate Brain
Until now neuroscientists have assumed that in primate brains simple
movements are "hard-wired" while complex behaviors are learned. Now,
however, studies are finding that a number of surprisingly complex
behaviors appear to be built into the brains of primates as well.
