Current research suggests that viral polymerase may provide a new therapeutic target for host-adapted avian influenza. The related report by Gabriel et al, "Spread of Infection and Lymphocyte Depletion in Mice Depends on Polymerase of Influenza Virus" appears in the September 2009 issue of the A... Read More
As noted entomologist E.O. Wilson accepts his 2007 TED Prize, he makes a plea on behalf of his constituents, the insects and small creatures, to learn more about our biosphere. Wilson states that as we're still discovering tiny organisms indispensable to life we're steadily, methodically, and vi... Read More
"This segment from a PBS program entitled "Evolution: Evolutionary Arms Race" illustrates the coevolution of the leafcutter ant and the fungi on which it feeds. Leafcutters have been "farming" this fungus for millions of years by feeding, fertilizing, weeding, and harvesting it. Learn how one gr... Read More
The soft flesh of a banana provides a ready source of DNA. Using a few simple purification steps in a classroom setting, students can yield loads of crudely prepared DNA. To begin, the banana is mashed in a detergent/salt solution to lyse the cellular and nuclear membranes. Cellular lysate is st... Read More
Scientists at UC Santa Barbara have discovered a potential new drug delivery system. The finding is a biological mechanism for delivery of nanoparticles into tissue. The results are published in the Proceedings of the National Academy of Sciences.

In a fundamental study of how to control protein shape, a UW-Madison research team has created a set of peptide-like molecules that successfully blocked HIV infection of human cells in laboratory experiments.
"By interacting with a piece of a crucial HIV protein called gp41, the synthetic mol... Read More
A new study suggests that when compared to conventionally raised beef cattle, organic and natural production systems do not impact antibiotic susceptibility of Escherichia coli O157:H7. This discovery emphasizes that although popular for their suggested health benefit, little is actually known... Read More
