Skin moles that sprout thick, long hairs produce signaling molecules that stimulate hair follicle stem cells to initiate new hair growth. This discovery may make baldness a thing of the past.
By combining calcium and electrical pacing, researchers designed a scalable protocol for culturing mature cardiac tissues from induced pluripotent stem cells.

A study finds that a baculovirus that infects cotton bollworm larvae changes the expression of genes involved in light perception, driving them to seek heights that could favor viral transmission.

Meanwhile, a paper to be published this month presents a detailed theory that ACE functions at the start of a signaling pathway common to major diseases that are other

Researchers at the National Space Biomedical Research Institute (NSBRI) are developing technologies to identify and monitor anticipated and unanticipated microorganisms in space--technologies, they suggest, that could also help to more efficiently diagnose medical conditions down here on Earth, as well as help detect biological hazards in this post-Sept. 11 world.1-3 Geo

You've probably seen the ads in the supermarket checkout aisle, or on radio and TV. "I lost 63 pounds with Hydroxycut," screams the headline in Cosmopolitan, above pictures of a woman going from corpulent to bathing-beauty trim in 19 weeks. "Diet Fuel changes the shape of your life," claims another ad, this time sporting an ab-flashing model in boxing gloves
Animal welfare activists, smarting from a defeat in Congress, plan to campaign across the United States to convince state legislators that laboratory rats, mice, and birds used in biomedical research require greater protection than afforded by federal law. Most major US research organizations, however, maintain that the 15 to 20 million animals used in labs--about 95% in biomedical research--are adequately protected under existing public and private regulations. More federal oversight, they sa
