how these cells improve sensory and motor function, and hopefully it will lead to further tests with people who suffer from these debilitating illnesses and injuries." Gabriel I. Nistor and Minodora O. Totoiu from UCI collaborated with Nadia Haque an...

less variety and too much ground cover, for example, as well as more cheatgrass and the potential fo...
What colour is that sound?
Hamilton, ON, Nov. 22, 2004 Imagine being able to see
or taste sounds, as well as hearing them. Sound like science fiction? For some people, it's reality. This blending of the senses occurs in a rare condition called "synesthesia." In this condition, a stimulus, such as sound, creates a reaction in a...

...long-term study, in a larger group of subjects, to see
if people on the low-GL diet can indeed keep off the lost pounds. Dr. Mark Pereira of the Children's Hospital Boston Department of Medicine (now at the University of Minnesota) was first author on the study. Children's Hospital Boston is recruiting a...

this as an extremely significant development in the race to cure cancer." Sandler hopes the treatment, which will allow physicians to treat nearly 20 types of cancer, is available by early 2007. Cancers most resistant to conventional treatments in...

if they could reverse the process and induce the new cells to become insulin-producing again. In the second stage of their study, the researchers exposed cultures of hIPCs to a serum-free medium. They saw a highly efficient, gradual transition from...

if stress reduction interventions, such as meditation, yoga or cognitive-behavioral therapy, would increase telomerase activity and telomere length -- or slow the rate of telomere shortening -- in individuals. At this point, there is not a routine te...

exactly where the new cells must be placed," Dr. Frauscher said. Stem cells are unspecialized cells capable of renewing themselves through cell division. Scientists believe that adult stem cells are located in small numbers throughout the tissues of ...
New pheromone creates buzz about the clout of older bees

whether they would quench the oxygen radicals cancer-causing substances that are destructive to normal cells. The limonoids appeared to be as effective as vitamin C in some of the tests. Test of cell viability were more impressive, however. The neu...
