mpacting upon water with a high velocity appears to explain partially why water striders have superhydrophobic legs, say the authors. Application of our study can be extended to developing semi-aquatic robots that mimic such insects having the surprising mobility on water.

ARTICLE #3 FOR IMMEDIATE RELEASE

Toward a Rosetta Stone for Microbes Secret Language
ACS Chemical Biology

Scientists are on the verge of decoding the special chemical language that bacteria use to talk to each other, British researchers report in a commentary article that appeared in the November issue of ACS Chemical Biology, a monthly journal. That achievement could lead to new treatments for antibiotic-resistant bacteria, including so-called superbugs that infect more than 90,000 people in the United States each year, they note.

David Spring, Martin Welch, and James T. Hodgkinson explain that researchers long have known that bacteria communicate with each other. Microbes release small molecules that enable millions of individuals in a population to coordinate their behavior. Disease-causing bacteria use this language to decide when to infect a person or other host. Decoding the structure and function of compounds involved in this elaborate signaling process, known as quorum sensing, could lead to new medicines to block the signals and prevent infect
