Researchers discover how bacteria sense their environments
Bacteria can sense in their environments changes in molecular concentrations as small as 0.1 percent, the equivalent of one drop diluted in a pool of a 1,000 drops. How do they do it? New Cornell research, highlighted on the cover of the May issue of Nature Structural and Molecular Biology, reveals that receptors assemble into a kind of cooperative lattice on a bacterium's surface to amplify infin ... read more

New test to detect rare proteins in blood
ELISA is a common immune-system-based assay that uses enzymes linked to an antibody or antigen as a marker for picking out specific proteins. For example, it is used as a diagnostic test to determine exposure to infectious agents, such as HIV, by identifying antibodies present in a blood sample. The sensitivity of detecting molecules by the new method, called FACTT, short for Florescent Amplificat ... read more
