Renewed interest from the biotech industry sparks hope for drugging the nucleic acid to treat cancer and other conditions.

Machine-learning algorithms tuned to detecting cancer DNA in the blood could pave the way for personalized cancer care.

Plants are locked in an ancient arms race with hostile viruses, but genome editing is giving crops the upper hand.

Viruses are incapable of reproducing without the help of a host, whose cells copy their genetic material and fabricate the building blocks of new virus particles.

From guiding branching neurons in the developing brain to maintaining a healthy heartbeat, there seems to be no job that the immune cells can’t tackle.

In addition to circulating in the blood as immune sentinels, macrophages play specialized roles in different organs around the body.

Scientists bring marine plankton back to life to study past climate change.

A study of off-target effects that sparked fear among investors of genome-editing companies receives methodological criticisms.

Environmental DNA is tracking down difficult-to-detect species, from rock snot in the U.S. to cave salamanders in Croatia.

Intensive aquaculture favors increasingly virulent forms of certain fish-infecting parasites and pathogens, studies show.

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
