What makes some clays powerful antimicrobial agents?

With funding from the National Institutes of Health-National Center for Complementary and Alternative Medicine, the UB geologists are studying the surface characteristics of a broad range of naturally occurring antimicrobial clays, including some clays from France to determine why they are such effective killers of bacteria.

New insights into how the brain takes in and assembles stimuli from the outside world

The area of the brain that processes sounds entering the ears also appears to process stimulus entering the eyes, providing a novel explanation for why many viewers believe that ventriloquists have thrown their voices to the mouths of their dummies.

Researchers show evidence of 'memory' in cells and molecules

Research to be reported October 29 in the journal Proceedings of the National Academy of Sciences (PNAS) provides evidence that some molecular interactions on cell surfaces may have a "memory" that affects their future interactions.

Discovery of new peptide communication factor in bacteria

Discovery by Hebrew University of Jerusalem researchers of a new communication factor that enables bacteria to "talk to each other" and causes their death could have significant consequences leading to development of a new class of antibiotic medications.

New magnetic separation 'traveling wave magnetophoresis' might detect multiple pathogens at once

A magnetic separation technique developed by researchers at Duke University's Pratt School of Engineering and Purdue University makes it relatively simple to sort through beads hundreds of times smaller than the period at the end of this sentence.

Hairpin-shaped mimetics imitate the helical protein that plays a role in the spread of HIV

When a host cell is infected with HIV, the virus brings its own genetic material into the host cell. This cell then replicates, reads the viral RNA, and uses it as a blueprint to produce more viral proteins.
