Researchers believe that within three months they will isolate the entire gene responsible for Duchenne muscular dystrophy, which would be a major step toward unraveling the mystery of the fatal disease that strikes one in every 3,300 males. Last fall, researchers at Boston Children's Hospital announced that they had identified the gene that causes the most common form of muscular dystrophy and isolated part of it.

The quadrillion synaptic connections among the neurons of a human brain ought to be enough to intimidate a researcher trying to delve into the mystery of thought, emotion and action. Molecular biologists Thomas Sudhof and Richard Scheller were apparently undaunted, and focused on a small but crucial part of the neurons. In the process, they managed to unlock the molecular mystery of the chemical communication that ties together this vast network of electrochemically firing cells into the most sophisticated computer on Earth.

The search for an HIV vaccine has taken an important step forward after researchers at the Scripps Research Institute in La Jolla managed to capture molecular images of a protein spike that allows the deadly virus to invade human immune cells to hack their genetic code. The ability to control and analyze that shape-shifting envelope trimer protein, which has evaded the best efforts of biochemistry for more than a decade, could offer researchers the ability to see whether they can induce natural antibodies to attack the virus' most vulnerable spot, a crucial step toward engineering a vaccine.

Every so often, we take a candid look at the private dietary lives of people whose food choices need a makeover. Up this week: the kitchen and dining habits of 22-year-old Jessica Watson and her boyfriend, 31-year-old Todd Preboski. She's a vegan; he eats fish but no other animal-based foods. Such diets may conjure up images of fresh vegetables and fruits, nuts, tofu and whole grains. But a lack of time and planning have cornered the couple into relying too often on Taco Bell burritos, protein bars and potato chips.

An implanted bridge of tissue has stimulated the regrowth of nerve cells to fix brain damage in rats and may one day help make similar repairs in the thousands of people who suffer spinal cord injuries each year, scientists reported Thursday. Researchers at UC San Diego and the La Jolla Cancer Research Foundation used microscopically thin strips of tissue made of fibrous material taken from human placentas.

Mary Beth Loughlin wore soft contact lenses for eight years, but now she's sick and tired of the hassle. "When they get gunked up with protein, there's all these different chemicals you have to use and they're expensive," the 24-year-old graphic designer says. "And my eyes must produce a lot of protein, because it was always a pain." Edith Lee, Loughlin's co-worker, adds this complaint about the soft contacts: "When you drop or lose them, they turn into Saran Wrap."

Scientists at UC San Francisco and the Chiron Corp. have taken the first step in development of a vaccine against chlamydia, the most common sexually transmitted disease in this country and a leading cause of blindness in the Third World. The researchers, led by molecular biologist Richard Stephens, have cloned and sequenced the gene for a protein on the surface of the chlamydia bacterium. The protein in turn could become the key ingredient in a vaccine.

Laurie Garrett assesses the importance of the Human Genetic Project by taking the opinions of scientists who get funding from the project and representatives of companies that intend to market products derived from the research ("Do We Really Want to Know All This" March 3). The article implies that one can "decipher" a gene simply by determining the sequence of nucleotides that compose the gene. In fact, determining the sequence is relatively easy; understanding the function of the protein specified by the gene is much harder.

By the light of day, the two transgenic baby rabbits look no different from their non-transgenic siblings -- white, fluffy and very cute. But put the whole litter under a black light, and you'll know exactly which two bunnies are special. They'll be glowing bright , fluorescent green. (For daylight and black-light shots of the transgenic rabbits and their littermates, see the photo gallery above). The glowing bunnies were born this month in a lab at the University of Istanbul.
