UCR chemists prepare molecules that accelerate chemical reactions for manufacturing drugs
Chemists at the University of California, Riverside have synthesized a new class of carbenes - molecules that have unusual carbon atoms - that is expected to have wide applications in the pharmaceutical industry, ultimately resulting in a reduction in the price of drugs.

Researchers discover ancient origins of tuberculosis-causing bacteria
In the new open access journal PLoS Pathogens, researchers report that M. tuberculosis and related strains recently emerged from a much more ancient bacterial strain.
