Cornell University engineers say they have developed a microvascular system that can nourish growing tissues, a step that may one day allow laboratories to grow synthetically engineered tissues for transplants.
By targeting a site in a mouse brain well connected to other areas, researchers successfully delivered a beneficial gene to the entire brain—after one injection of gene therapy. If these results in animals can be realized in people, researchers may have a potential method for gene therapy to treat a host of rare but devastating congenital human neurological disorders, such as Tay-Sachs disease.
Contrary to an earlier report, smoking appears to have no effect on the progression of multiple sclerosis, according to a study published in the Oct. 9, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

High-risk teenagers who participate in peer-led substance abuse prevention programs reduce their drug use by approximately 15 percent versus traditional curricula, suggests a study led by researchers at the University of Southern California (USC).
A low-fat vegetarian diet is very efficient in terms of how much land is needed to support it. But adding some dairy products and a limited amount of meat may actually increase this efficiency, Cornell University research suggests.
A special protein can be injected into the body to reverse learning problems in mice that have an animal version of Alzheimer’s disease, Saint Louis University researchers have found.
Taking antidepressants together with painkillers can substantially increase the risk of bleeding from the stomach, according to new research by the University of East Anglia.
University of Cincinnati (UC) radiologists have developed a new technique for capturing images of chest veins that eases diagnosis of venous diseases.
Scientists may have discovered a new way of killing tumours in what they hope could one day lead to alternative forms of cancer treatments.
