A research team, led by UC Riverside's Ludwig Bartels, was the first to design a molecule that can move in a straight line on a flat surface. Now this team has found a way to attach cargo: two carbon dioxide molecules, making the nano-walker a molecule carrier.

Many cancer patients who have heart attacks often are not treated with life saving aspirin given the belief in the medical community that they could experience lethal bleeding. Researchers at the University of Texas M. D. Anderson Cancer Center, however, say that notion is now proven wrong and that without aspirin, the majority of these patients will die.

University of Central Florida and University of California Riverside professors are a step closer to being able to deliver life-saving drugs through tiny molecules that would travel through the bloodstream and destroy only cancer-ridden cells.

Researchers at Rush University Medical Center analyzed the data from 22 randomized clinical trials, and have found significant differences between antihypertensive drugs. ACE-inhibitors and the newer angiotensin receptor blockers, or ARBs prevent people from getting diabetes, and the older diuretics or beta-blockers, increase the chance that a person becomes diabetic, compared to either placebo (inactive sugar-pills) or calcium channel blockers according to a study published in the January 20, 2007 issue of the Lancet.

International time coordination is improving thanks to a low-cost system relying on Global Positioning System (GPS) satellites and the Internet, which enables much faster time comparisons and gives small countries the opportunity to easily evaluate their measurements in relation to others and to world standards.
