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.
Which mattered first at the dawn of life: proteins or nucleic acids? Proteins may have had the edge if a theorized process let them grow long enough to become self-replicating catalysts.
An unexpected mechanism allows wasps to rapidly co-opt genes for new toxic functions.
The proteins that unravel as the temperature starts to rise turn out to be among the most vital.
Without viruses, we might never have evolved.
