...read with fascination about the Soviets doing eye surgery in an assembly-line fashion [MEDICINE, July 1]. However, I was surprised to notice in your photograph that one eye surgeon had his nose outside the sterile mask. I guess that person has three minutes to infect each patient. Richard C.

...small molecule could be induced to bind to that pocket, it would inhibit the shape transformation the virus would need to undergo in order to infect target cells...
...Bird flu has already killed 32 of the 44 people infected in Asia this year, and the news isn't getting better. Fortunately the only way the disease seems to spread to humans is through close contact with infected birds, although rare cases of human-to-human transmission have occurred. But if bird flu mutates and gains the ability to transmit as easily as normal flu-and scientists say that is a real possibility-it could trigger a worldwide pandemic similar to that in 1918. That prospect was raised last week, when Dr. Shigeru Omi, the World Health Organization...
...apparently the first documented case of human-to-human bird-flu transmission, researchers suspect that such dead-end transmissions have occurred in previous outbreaks and simply escaped notice. "It's worrisome on one hand, but on the other hand it's nothing new," says Stohr. "Occasionally it can infect the next person, but then the infection chain stops...
...effect, to learn to read an organism's genetic language. In classical genetics, scientists usually mutate an organism, see how its functions have changed (a mutated virus might no longer be infectious) and then work back and identify which gene mutated. If a mutated virus loses its ability to infect a cell, then that gene probably has something to do with infectivity. In chemical genetics, explains Dr. Richard Kao, the lead researcher on the HKU study, scientists try do the same by testing thousands upon thousands of chemicals on virus samples. The vast majority won't have any effect...
