Viruses of soil bacteria (phages) evolve to improve their ability to infect the bacterial hosts that surround them. This is shown in a new study by Dutch researcher Michiel Vos, published in the journal Science. Phages appear to be better able to infect bacteria from the same small soil sample t... Read More
Molecular biology for years meant breaking down living cells to their smallest component parts, the genes and proteins that govern what a cell does. But a list of parts tells only so much. To understand how living cells really work, biologists are now trying to visualize how the parts are assemb... Read More

With the unanticipated shortage of the new H1N1 swine flu vaccine, my life as a practicing internist suddenly changed. My office phone began ringing off the hook with worried calls. Fear of the new, unknown vaccine was suddenly replaced by fear of not having it.
This panic was overblown, as t... Read More
Ever since the previously unknown SARS virus emerged from southern China in 2003, University of Texas Medical Branch at Galveston virologists have focused on finding the source of the pathogen's virulence -- its ability to cause disease. In the 2003 epidemic, for example, between 5 and 10 percen... Read More

Andrew Logan has what every manufacturer craves: an endless source of free raw materials that his suppliers can't wait to dump and a market starving for his product.
Logan, a biologist in Idaho Springs, Colo., turns waste from breweries into a fish-food ingredient. His company, Oberon FMR, sp... Read More
The urge to celebrate during the darkest part of the year - to feast, to sing and talk story about great stars (the sun), to burn candles for divinity or our own inner light - seems nearly universal. Our ancestors learned that the nights shortened as surely as they had lengthened, that the sun p... Read More
