Exercise, calorie restrictions can rejuvenate older synapses
Harvard researchers have uncovered a mechanism in mice through which caloric restriction and exercise delay some of the debilitating effects of aging by rejuvenating the connections between nerves and the muscles that they control.
Researchers discover that gut bacteria affect multiple sclerosis
Biologists at the California Institute of Technology (Caltech) have demonstrated a connection between multiple sclerosis (MS)—an autoimmune disorder that affects the brain and spinal cord—and gut bacteria.
HIV prevention science scores a victory — the gel works!
Today at the XVIII International AIDS Conference in Vienna, Austria, members of the International Rectal Microbicide Advocates (IRMA) and thousands of other HIV advocates and scientists cheered a long-awaited, much anticipated success in the quest for new HIV prevention technologies.
Novozymes reveals knowledge on new antibiotic against resistant bacteria
Scientists from Novozymes have now found the mechanism by which plectasin, an anti-microbial peptide, kills bacteria that cause severe infections in humans. Peptide antibiotics such as plectasin have retained antibiotic activity throughout evolution.
First Self-Replicating, Synthetic Bacterial Cell Constructed by J. Craig Venter Institute Researchers
Researchers at the J. Craig Venter Institute JCVI, a not-for-profit genomic research organization, published results today describing the successful construction of the first self-replicating, synthetic bacterial cell.
Bran Reduces Heart Disease Deaths
People with diabetes who eat plenty of bran-rich whole grains appear to have a reduced risk of death from heart attack, stroke, and other cardiovascular causes, a new study shows. Researchers from Harvard University followed almost 8,000 nurses with type 2 diabetes for almost three decades.
Examining Individual Tumor Cells
Despite decades of research into cancer biology, researchers still dont fully understand what happens to the malignant cells DNA as they mutate. Its not an idle question: The better biologists appreciate how DNA changes, the better they can create therapies that specifically target the disease.
Olive Oil May Cut Risk of Ulcerative Colitis
Two or three tablespoons a day of olive oil may help protect against ulcerative colitis, preliminary research suggests.In a new study, people with the highest consumption of oleic acid — a monounsat
