Scientists working at a secured lab in Montana say a human antibody proved highly effective in guarding against a rare but highly lethal virus in a primate study. Investigators injected the deadly Hendra virus--which has killed about half of the people infected by it--in 14 African monkeys. Twelve of those monkeys were treated with the m102.4 antibody and lived. The two untreated monkeys both died.

A team of researchers led by the Sanger Institute and the University of Cambridge used cutting-edge methods to correct a genetic mutation in stem cells derived from a patient's skin biopsy, and then grew them into fresh liver cells.

Modern medicine’s ability to save lives through organ transplantation has been revolutionized by the development of drugs that prevent the human body from rejecting the transplanted organ.  But those antirejection drugs have their own side effects — sometimes serious.

Scientists in the US were able to normalise blood sugar levels in diabetic mice by injecting them with a compound, nicotinamide mononucleotide (NMN). At the same time the jabs lowered raised levels of cholesterol and triglyceride blood fats.

Over the next five years, National Institutes of Health (NIH)-funded researchers will extensively test and generate data about mice with disrupted genes to gain clues about human diseases. NIH today awarded a set of cooperative agreements totaling more than $110 million to begin the second phase of the Knockout Mouse Project (KOMP).

A protein linked to Alzheimer's disease kills nerve cells that detect odors, according to an animal study in the September 28 issue of The Journal of Neuroscience. The findings shed light on why people with Alzheimer's disease often lose their sense of smell early on in the course of the disease.

Cystic fibrosis (CF), a chronic disease that clogs the lungs and leads to life-threatening lung infections, is caused by a genetic defect in a chloride channel called cystic fibrosis transmembrane conductase regulator (CFTR). Although scientists do not fully understand how or why this defect occurs, a team of researchers at The Hospital for Sick Children (SickKids) in Toronto, Ontario, Canada has found a promising clue: a protein called ubiquitin ligase Nedd4L.

Only 40 years ago it was widely believed that if you lived long enough, you would eventually experience serious cognitive decline, particularly with respect to memory. The implication was that achieving an advanced age was effectively equivalent to becoming senile—a word that implies mental defects or illness.

Researchers have shown previously that maternal stress during pregnancy may have negative consequences for the fetus, both in humans and laboratory animals. A new study from the University of Pennsylvania suggests that in mice, such impacts - namely, an increased sensitivity to stress - are passed along even to the fetus' children.

In a finding that could open the door to new drugs for chronic, long-lasting, unrelenting pain, British scientists have discovered a gene that, when knocked out in mice, abolishes nerve pain - one of the most common and difficult to treat pain conditions.

Mayo Clinic researchers have developed a genome-based immunization strategy to fight feline AIDS and illuminate ways to combat human HIV/AIDS and other diseases. The goal is to create cats with intrinsic immunity to the feline AIDS virus. The findings — called fascinating and landmark by one reviewer — appear in the current online issue of Nature Methods.
