Proteins

Neural networks have been taught to quickly read the surfaces of proteins — molecules critical to many biological processes.

Maintaining perfect stability through negative feedback is a basic element of electrical circuitry, but it’s been a mystery how cells could do it — until now.

Genetically identical bacteria should all be the same, but in fact, the cells are stubbornly varied individuals.

The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.

Viruses and other parasites may sync with their host’s biological clock — or reset it — to gain an advantage.

Jennifer Doudna, one of CRISPR’s primary innovators, stays optimistic about how the gene-editing tool will continue to empower basic biological understanding.

With proteins that reversibly self-assemble into droplets, cells may control their metabolism — and harden themselves against harsh conditions.

For decades, an origin-of-life story starring RNA has prevailed. New research may be shaking that theory’s hold on our understanding of life’s beginnings.

Preserving its DNA ought to be a cell’s top priority. But bacteria slow their DNA repair to a crawl in favor of proofreading gene transcripts.
