What to know about Institutional Achievement

Researchers at the University of Delaware have used cryo-EM imaging to identify a molecular switch in the GdpP enzyme that helps bacteria like MRSA survive antibiotic exposure. The team suggests that developing companion drugs to disable this switch could enhance the effectiveness of existing antibiotics and potentially aid in cancer immunotherapy.

What happened

Why it matters

"It sounds gross, but not all bacteria are bad; most of them are good.

Common ground

The trouble starts when the bad bacteria learn how to outsmart antibiotics." The rise of antibiotic-resistant bacteria has become one of the world's greatest public health threats.
