The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.
CAPTCHAs are a key part of the arms race between AI deceivers and AI deception detectors. A computer scientist explains how they work.
Bio-inspiration takes cues from natural structures that do certain things very effectively. One example: the strong but flexible fibers that sea sponges use to anchor themselves to the ocean floor.
Researchers have grown the first human-monkey hybrid embryos as well as mouse embryos in artificial wombs late into development. These biomedical breakthroughs raise different ethical quandaries.

AI has the potential to help prevent and detect abuse, but only if it avoids bias and is sensitive toward traumatized people’s needs.
Are DNA samples today’s version of the human skeletons that hung in 20th-century natural history museums? They can provide genetic revelations about our species’ history – but at an ethical price.
