NewsAnti-CRISPR stops the protein assembly line in bacteria
Bacteria fend off invading viruses with molecular scissors that slice up viral DNA, but viruses can fight back with a molecular trick that stops the scissors from ever being made. A viral “anti-CRISPR” protein sits on the ribosome and jams it as a CRISPR protein named Cas12 begins to form.

NewsNew molecular movie reveals how antibiotic resistance to fusidic acid works
Researchers revealed how FusB, a resistance protein found in clinically resistant strains of the bacterium Staphylococcus aureus, can rescue ribosomes from the antibiotic fusidic acid. FusB works like a molecular crowbar to free the blocked ribosome.

NewsBacteria ditch tags to dodge antibiotics
Bacteria modify their ribosomes when exposed to widely used antibiotics, according to new research. The subtle changes might be enough to alter the binding site of drug targets and constitute a possible new mechanism of antibiotic resistance.
