As even the most casual observer of nature knows, males and females frequently differ in body size, form and structure. But how these differences have developed – a topic studied for decades by evolutionary biologists – is not as clear.
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.
Depression in the elderly increases the risk of subsequent mental impairment and can act as a predictor of future intellectual decline, University of Rochester Medical Center psychiatrists and researchers have found.
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 team led by researchers at the UCSF Positive Health Program has been named to receive $15 million over five years to expand understanding of the complex interactions between HIV and the immune systems of newly infected patients following HIV transmission.
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.
University of Cincinnati (UC) radiologists have developed a new technique for capturing images of chest veins that eases diagnosis of venous diseases.
A drug to treat colon cancer is proving much more convenient than traditional chemotherapy, has fewer side effects – and a study of almost 2,000 patients has shown it is giving them a better chance of surviving the disease.
