Cell communication secrets revealed at SBC A model of the structure of the TraR protein
A method that cells use to communicate and coordinate activities has been confirmed by researchers from Cornell University, Monsanto Co. and Argonne. This work could lead to new drugs to fight such environmental tasks, such as filtering water.

Biologists have theorized that bacteria communicate by releasing and sensing chemical pheromones to detect their population densities. This activity is termed "quorum sensing."

Using Argonne's Structural Biology Center (SBC), the researchers confirmed this theory. They determined the molecular structure of a key protein - TraR - in this interbacterial communication and witnessed how TraR acts as a relay to sense pheromones and then activate genes to create biofilms. A common example of a biofilms. A common example of a biofilm is the scum found on ponds. more >>

Good-neighbor Argonne helps high-tech companies Aerial view of the Advanced Photon Source at Argonne National Laboratory
High-tech companies are increasingly turning to Argonne National Laboratory's world-class research facilities to keep their products on top of the market. And the local community is reaping the benefits.

Despite widespread economic uncertainty, the past year again saw increasing numbers of industrial scientists using such Argonne facilities as the Advanced Photon Source (APS) for research. Argonne's presence helps companies attract some of the country's best scientific talent to the local area, and Argonne facilities allow these firms to develop new products faster and cheaper. more >>

Using the synchrotron beam at the APS, the team is able to probe the fuel spray and study the process of combustion in a diesel-like environment. The goal is to create cleaner, more efficient engines.X-rays expose secrets of diesel combustion
Groundbreaking research in the use of X-ray beams to analyze diesel fuel injector sprays may lead to higher efficiency in diesel engines that use fuel injection systems.

The Argonne research team, which includes Jin Wang of the Experimental Facilities Division and Steve Ciatti, Christopher Powell and Yong Yue of the Energy Systems Division, won the U.S. department of Energy's 2002 National Laboratory Combustion and Emissions Control R&D Award. more >>
