Antibiotic Resistance: Researchers Succeed in Blocking Genes of Resistance

News

Scientists have come up with a novel approach to block the transfer of resistance genes between bacteria via plasmids. Libraries of small chemical molecules were screened for those that bound an essential component of the plasmid transfer machinery. Analysis by X-ray crystallography revealed the exact binding site of these molecules.

Raw Cat Food Could Spread Antibiotic-Resistant Bacteria
News

Scientists have found that raw cat food was associated with contamination of cats' feces with Enterobacteria that contained the enzyme beta-lactamase. This particular enzyme is important because it can break down a chemical structure called the lactam ring. This is important because it forms a part of numerous antibiotics - no lactam ring, no antibiotic activity.

Physicists Develop Faster Way to Make Bose-Einstein Condensates
News

Physicists have invented a new technique to cool atoms into condensates, which is faster than the conventional method and conserves a large fraction of the original atoms. The team used a new process of laser cooling to cool a cloud of rubidium atoms all the way from room temperature to 1 microkelvin, or less than one-millionth of a degree above absolute zero.
