U.S. Forest Service scientists believe an Oregon State University graduate student working on a cooperative project with the agency’s Pacific Southwest Research station on the Tahoe National Forest has photographed a wolverine, an animal whose presence has not been confirmed in California since the 1920s.

UC Irvine researchers have discovered a dramatically improved method for genetically manipulating human embryonic stem cells, making it easier for scientists to study and potentially treat thousands of disorders ranging from Huntington’s disease to muscular dystrophy and diabetes.

Worldwide, an average 95.4 percent of LASIK patients are satisfied with their new vision, according to the first review of the world body of scientific literature, the American Society of Cataract and Refractive Surgery (ASCRS) announced today.

Scientists in Japan have discovered a new species of bacteria that can live in hairspray, according to the results of a study published in the March issue of the International Journal of Systematic and Evolutionary Microbiology.

It will soon be possible for anyone over 60 to predict their individual risk of bone fracture with the aid of a simple web-based tool, developed by the Sydney-based Garvan Institute of Medical Research.

A group of researchers has developed a novel way to view the world through the eyes of a common fly and partially decode the insect’s reactions to changes in the world around it. The research fundamentally alters earlier beliefs about how neural networks function and could provide the basis for intelligent computers that mimic biological processes.
