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.
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.
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.
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.
