Plagued by potholes? A special composite patented by the University of Illinois -- and now commercially available -- may pave the way to smoother, longer-lasting roads.
If you are what you eat, do you eat whatever's before you? Apparently so, at least when it comes to snack foods where size has become a major ingredient in marketing.
1) Severely ill children mainstreamed in schools--impact of March 3 Supreme Court decision; 2) Y2K risks in health care--on March 2, Senate panel warned of "significant potential for harm;" 3) Dioxin and Mercury "fallout" from health care poses grave risk, but EPA standards on medical waste incineration are "irrational" said Federal appellate court on March 3.
A metal-making process known to the ancient Romans could be pressed into service to bring Mars into the Iron Age - and start opening the solar system to human habitation.
In a study of elderly men, researchers found that mid-life health problems -- such as high blood pressure -- speed up aging of the brain and increase the risk for stroke during late-life. The study appears in this month's Stroke: Journal of the American Heart Association.
So that police will not have to routinely evacuate an area and blow up stray packages, Sandia has developed a technique to determine if they contain bombs. A remotely controlled, motorized cart will roll an X-ray device to the scene.
Between 1977 and 1996, the percentage of children who were uninsured increased substantially, but the increase occurred almost exclusively among children living with only one parent. This is one finding of a new study that examined health insurance trends specifically focusing on children's family structure and their health insurance coverage.
Exercise should serve as a prescription for the prevention of heart disease, Boston University School of Medicine researchers reported in the February 23 issue of the American Heart Association journal Circulation.
For the first time ever, University of Iowa researchers have confirmed how a protein complex, when defective, causes limb girdle muscular dystrophy.
For three decades, geologists have been mystified by one of the world's largest disappearing acts: How could the boundary between two immense continental plates be geologically detectable for a long stretch, then vanish from scientific view?
Future telescope could shatter solar high-resolution barrier.
Scientists who recently developed new molecules that simultaneously absorb two photons of light report that the molecules are sensitive enough to laser light that a myriad applications in materials science and photonics are possible.
