Small molecule interactions were central to the origin of life

In an important new paper forthcoming in the June issue of The Quarterly Review of Biology, Robert Shapiro (New York University) argues against the widely held theory that the origin of life began with the spontaneous appearance of a large, replicating molecule such as RNA.

Renewed interest in studying influenza A viruses

The emergence of the avian influenza virus H5N1 that is currently devastating chicken flocks in many countries and threatening to unleash a worldwide epidemic among humans has triggered a renewed interest among scientists in studying influenza A viruses, according to investigators at St. Jude Children's Research Hospital.

Gene silencing protein discovered

A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off -in this case, the turning off of thousands of nearly identical genes in a hybrid plant.

New technique to speed discovery of drug targets in chemical genetics

Researchers at Fox Chase Cancer Center have developed a new technique to speed discovery of drug targets in chemical genetics. Fox Chase researcher Jeffrey R. Peterson, Ph.D., and his colleagues describe a new way to swiftly find the proteins targeted by small molecule inhibitors during high-throughput screening (HTS) experiments. The new work offers a critical solution to a common stumbling block in this booming field of drug discovery.

Anthrax killed by protein that explodes cell walls

Not all biological weapons are created equal. They are separated into categories A through C, category A biological agents being the scariest: They are easy to spread, kill effectively and call for special actions by the pubic health system. One of these worrisome organisms is anthrax, which has already received its fair share of media attention. But work in Vince Fischetti's laboratory at Rockefeller University suggests that a newly discovered protein could be used to fight anthrax infections and even decontaminate areas in which anthrax spores have been released.
