Argonne biochemist Daniel Schabacker could be considered a Sherlock Holmes of bioterrorism. Although he doesnt carry around a pipe and magnifying glass as he attempts to nab the culprit, he has a far more powerful deductive tool: the biochip.

Scientists at Battelle and Fluid Imaging Technologies (Yarmouth, ME) have designed a sensor that can not only better measure changes in the levels of toxic red tide in oceans and algae blooms in the Great Lakes, but also monitor close-to-home problems such as the increase of odor-causing organisms in the public water supply.

For two decades, scientists have been pursuing a potential new way to treat bacterial infections, using naturally occurring proteins known as antimicrobial peptides (AMPs). Now, MIT scientists have recorded the first microscopic images showing the deadly effects of AMPs, most of which kill by poking holes in bacterial cell membranes.
