...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...
...know there will be a pandemic; we just don't know when it will be." DICK THOMPSON, World Health Organization spokesman, on last week's revelation that avian flu has spread to pigs in China, exacerbating fears that it might also infect a large number of humans...
...virus to create a highly lethal, highly contagious strain with the potential to cause a global flu pandemic. Professor Yi Guan of the University of Hong Kong, the lead researcher on the Nature paper, worries that H5N1 is evolving so fast that it may gain the ability to infect humans by mutating on its own, without mixing with a human virus, much as SARS did. Yi says the latest outbreaks show that the virus has become endemic to the region, with a difficult-to-eradicate foothold in migratory birds, creating a biological time bomb that could go off without warning...
...winter's lethal outbreak. Professor Yi Guan of the University of Hong Kong worries that H5N1 is evolving so fast that it may gain the ability to infect humans simply by mutating on its own. "We must face the problem, not avoid it," says Yi - or the problem will face us soon enough. - By Bryan Walsh. With reporting by Matthew Forney Sentence Shelved SWEDEN A Stockholm appeals court overturned the life sentence of Mijailo Mijailovic, the convicted murderer of Foreign Minister Anna Lindh, ruling that he should instead be sent to a psychiatric unit for treatment. The court upheld...
...obligate” airborne disease is one that only infects people via aerosol. Preferential airborne diseases can be transmitted in other ways, but spread primarily through aerosol. The “opportunistic” category includes diseases that generally infect people through other means, but may be transmitted through the lungs as well...
