The bacteria responsible for chronic infections in cystic fibrosis patients use one of the sugars on the germs’ surface to start building a structure that helps the microbes resist efforts to kill them, new research shows. Scientists have determined that the bacterial cell-surface sugar, a polys... Read More

Americans burn through 140 billion gallons of gasoline a year. And even if drivers switch to more fuel-efficient cars and trucks, the nation’s fuel needs are expected to increase by a fifth over the next 20 years, thanks to dramatic increases in car and airplane use. Which is why, in addition to... Read More
The ocean tides mirror life itself. Their ebb and flow pay homage to the cyclic nature of the cosmos along even the most secluded seashores. But is life itself also ultimately a fluke of the tides?
If so, life may ultimately owe its origins to our serendipitously large moon. The sun and wind ... Read More
Agricultural Research Service (ARS) scientists have uncovered genetic evidence about the evolutionary path that transformed Salmonella enteritidis from an innocuous bacterium into a virulent pathogen. S. enteritidis, like many bacteria, reproduces very quickly--every 20 minutes in optimal condit... Read More
An unusual pattern of avian flu cases in Egypt — almost all are in toddlers, all of whom have survived — has led some flu-tracking Web sites to speculate that dozens of silent cases are circulating there. However some experts like Dr. Robert G. Webster, say “I hope to hell it’s not happening, be... Read More
The International Federation of Red Cross and Red Crescent Societies has made an emergency appeal for millions of dollars to fight a new polio outbreak across Africa. Despite more than 20 years of eradication efforts, two strains of polio have spread out from northern Nigeria and northern India ... Read More
UK microbiologist Mark Pallen has commissioned a rap version of Darwin's theory of evolution by Baba Brinkman, a former English literature student and Canadian hip hop artist. The idea is that the music can serve as a pedagogical tool for students. There is also a nice video of it on YouTube her... Read More
Take 1 part brewer's yeast, add a gene from a salt marsh plant, grow it with an obscure microbe from a French landfil and viola! Biofuel. Christopher Voigt, a synthetic biologist at UCSF, "and colleagues had assembled the perfect microbial team – A. fermentans converts cellulose into acetate, w... Read More
In just about every major contaminated food scare, Minnesotans become sick by the dozens while few people in Kentucky and other states are counted among the ill. Contaminated peanuts? Forty-two Minnesotans were reported sick compared with three Kentuckians. Jalapeño peppers last year? Thirty-on... Read More
Scientists in South Dakota are reporting development of the first broad-spectrum antimicrobial paint, a material that can simultaneously kill not just disease-causing bacteria but mold, fungi, and viruses. Designed to both decorate and disinfect homes, businesses, and health-care settings, the p... Read More
Freshwater algae can dance around each other in stable groups, held together only by fluid flows in the surrounding water. In fact they have two dances, the waltz and the minuet. There is a nice video that accompanies this article as well.
Scientists at the Cambridge University have discovered that freshwater algae can form stable groupings in which they dance around each other, miraculously held together only by the fluid flows they create. The researchers studied the multicellular organism Volvox, which consists of approximately... Read More
