HIV, the virus that causes AIDS, depends on more than 250 human genes to grow, a finding that reveals the lethal virus' weakness and may lead to new ways to attack it, scientists said. By blocking genes in infected cells, scientists tied the virus' survival to processes of protein transport, entry to the nucleus and cellular self-destruction, Harvard University scientists said in a study released today by the journal Science. With just nine genes that make 15 proteins, HIV must assume control of the protein-making machinery of infected cells to reproduce itself.

We're about halfway through the Islamic holy month of Ramadan. This is the time of year when an estimated 1.6 billion Muslims worldwide abstain from eating, drinking, smoking and sex during daylight hours. That's right -- we give up food, water, coffee and even cronuts from sunup to sundown to commemorate God's revelation of Islam's holy book, the Koran, to the Prophet Muhammad. Instead of spending afternoons with friends at Starbucks, Muslims focus on achieving self-discipline and reflection, while feeling the plight of those less fortunate.

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.

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.

Surgeons who repair bones are closely watching clinical experiments on a "bone glue" discovered at UCLA. If it works as expected, orthopedic, plastic and dental surgeons will apply it to human tissues to promote fresh, new bone development, strengthen the bond between living bone and artificial joints or prostheses, and speed healing. The glue is a protein found in powders made from the bones of humans, cows and pigs.

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."

It's too late to lose that unwanted weight for summer. But if you start now - and aim to shed a modest 2 pounds a week - you could drop as much as 40 pounds in time to ring in 2013. The hardest part, however, might be choosing a new diet. This season's crop of cookbooks includes a whiplash-inducing array of advice. For every book urging you on to eat: More carbs! More protein! More fat! there's another seemingly well-reasoned argument to do the opposite. As if this isn't confusing enough, there's a new bogeyman on the diet scene: gluten.

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.
