Lab-grown viruses make cancer cells resemble pig tissue, provoking an organ-rejection response.

The president-elect quickly nominated confidantes with a focus on AI, but their recommendations for the rest of science remain unclear.

A mutation in neurons grows for decades before it reaches a deadly limit.

Research also suggests how to make homes more resilient in the aftermath of deadly blazes in Los Angeles’.

Nations consider increasing universities’ involvement in military research.

A phase I clinical trial of GD2-CAR T cells (immune cells engineered to target the molecule GD2) in children and young adults with diffuse midline gliomas — incurable cancers of the central nervous system — shows promising results. Several trial participants exhibited substantial improvements, and one child’s tumour has been undetectable for more than three years.

Evidence from 2,000-year-old DNA reveals that women in Celtic society stayed in their ancestral communities after marriage, whereas men were mobile, and that the southern coast of Britain was a hotspot for cultural exchange.

Machine-learning system can process words spoken in 101 languages, spitting out voice-synthesized translations in 36 target languages.

Promoting mutually beneficial relationships between plants and soil microbes that enhance nutrient acquisition by plants could improve crop production without increasing inorganic-fertilizer use. A mutation that causes an amino-acid substitution in a channel called CNGC15 in the plant cell’s nucleus boosts the formation of such endosymbiotic relationships.

US technology company Meta has produced an AI model that can directly translate speech in one language to speech in another. Two scientists discuss the technical feats and ethical questions that underpin this advance in machine translation.

The US federal government can harness science to secure the health, prosperity and safety of Americans and the world.

Research and teaching pressures can exacerbate anxiety and depression, causing many young scientists to consider quitting, a survey finds.

A survey highlights the emotional toll of retractions for authors and what could be done differently.

Researchers need to define ‘safe zones’ for joint work in which the benefits outweigh the political risks. Here’s how.

Proteins made using machine learning successfully bind snake toxins — plus, Earth’s temperature breaks a significant climate threshold for the first time.

A pair of spacecraft developed by private firms blast off on a single rocket on the risky voyage to the lunar surface.
