Researchers demonstrate how ‘interfering’ RNA can block bacterial evolution

Experiments in pneumococcal bacteria show how an RNA interference mechanism known as CRISPR can be used to prevent the uptake of genetic material from the environment. Harnessing this mechanism could be a new way to manipulate bacterial evolution in ways that might be medically useful. More »

Microbiologist to join Rockefeller faculty

Rockefeller’s newest faculty member is Luciano Marraffini, a microbiologist who studies how bacterial pathogens modulate the transfer of foreign DNA into their genomes. His work sheds light on how bacteria such as Staphylococcus aureus evolve, including how they gain the ability to resist antibiotic drugs. More »
