Bacteria gauge cold with molecular measuring stick

Some bacteria react to the cold by subtly changing the chemistry of their outer wall so that it remains pliable as temperatures drop. Scientists identified a key protein in this response mechanism a few years ago, but the question of how bacteria sense cold in the first place remained a mystery.... Read More

Key difference in how TB bacteria degrade doomed proteins

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have discovered a key difference in the way human cells and Mycobacterium tuberculosis bacteria, which cause TB, deliver unwanted proteins — marked with a "kiss of death" sequence — to t...

Improved Antibiotic Coatings: Research Aims to Make Medical Devices Safer by Preventing Biofilms

Bacteria have a natural ability to attach themselves to surfaces, both natural and synthetic. Once attached, they often work cooperatively to form biofilms, thin layers of bacterial colonies that can coat the surface of a medical device and introduce the risk of infection. As a result, orthopedi... Read More
