A new antimicrobial approach can kill bacteria in laboratory experiments and eliminate life-threatening infections in mice by interfering with a key bacterial nutrient, according to research led by a University of Washington scientist. The joint project, conducted at the UW, the University of Iowa, and the University of Cincinnati, will be featured in the April 2 issue of the Journal of Clinical Investigation.

To address the high rate of multiple births resulting from in-vitro-fertilization (IVF), researchers at Yale School of Medicine and McGill University have developed a procedure that estimates the reproductive potential of individual embryos, possibly leading to a decrease in multiple-infant births and a higher success rate in women undergoing IVF.

A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases – sunlight blocked by dust, pollution and other aerosol particles – appears to have lost ground.

University of Florida researchers have used an experimental therapy in mice to shut down a gene that plays a crucial role in a leading cause of inherited blindness.

A new study sheds additional light on how erectile dysfunction (ED) interacts with diabetes. The study is another step in uncovering the link between the two disorders, and may lead to improved efficacy in treatments.

Scientists have discovered that the clouded leopard found on the islands of Borneo and Sumatra is an entirely new species of cat. The secretive rainforest animal was originally thought to be the same species as the one found in mainland Southeast Asia.

The success of long term hip replacement surgery may lie in the genes, suggests research published ahead of print in the Annals of the Rheumatic Diseases.

Video evidence that an extinct woodpecker is alive and well in Arkansas, USA may prove to be a case of mistaken identity. Research published today in the open access journal BMC Biology shows how fleeting images thought to be the Ivory-billed Woodpecker Campephilus principalis could be another native woodpecker species.

The problem of efficiently delivering drugs, especially those that are hydrophobic or water-repellant, to tumors or other disease sites has long challenged scientists to develop innovative delivery systems that keep these drugs intact until reaching their targets.
