The RecBCD enzyme is important for both restriction of foreign DNA and recombinational DNA repair. Switching enzyme function from the destructive antiviral state to the productive recombinational state is regulated by the recombination hotspot, χ (5′-GCTGGTGG-3′).
Dr. Knowles’s work helped to advance treatment for Parkinson’s disease.

Researchers have discovered how soil bacteria carry out surprising chemistry, defying a longstanding set of chemical rules and thus paving the way for new synthesis of polyether drugs.
Inspired by the paper-folding art of origami, chemists have developed a 3-D paper sensor that may be able to test for diseases such as malaria and HIV for less than 10 cents a pop. The sensors can be printed out on an office printer, and take less than a minute to assemble.
The traditional way of making medicines in a factory may be joined by a new approach in which doctors administer the ingredients for a medicine separately, and those ingredients combine inside patients’ bodies. That’s one promise from an emerging field of chemistry, according to its founder.
Researchers have created a new, unifying method to describe a basic chemical concept called "electronegativity," first described almost 80 years ago by Linus Pauling and part of the work that led to his receiving the Nobel Prize.
Over their 3.8 billion years of evolution, living organisms have developed countless strategies for monitoring their surroundings. Chemists have adapted some of these strategies to improve the performance of DNA detectors. Their findings may aid efforts to build better medical diagnostics, such as improved HIV or cancer tests.
