The news: Radiologists assisted by an AI diagnose breast cancer more successfully than when they work alone, according to new research. That same AI also produces more accurate results in the hands of a radiologist than it does when operating solo.
Why it’s important: The large-scale study, published this month in The Lancet Digital Health, is the first to directly compare an AI’s performance in breast cancer diagnosis according to whether it’s used alone or to assist a human expert. The process meant that close to three-quarters of screening studies didn’t need to be reviewed by a radiologist, which could help to ease the global shortage of specialists.
What happens next: While the findings are promising, the next step would be to confirm how well the AI performs over a long period of time in actual clinics with real patients. The hope is that in the future, such systems could save lives by detecting cancers doctors miss, freeing up radiologists to see more patients, and easing the burden in places where there is a dire lack of specialists.

Materials with nanoscale components will change what’s possible
Materials scientists have long been fascinated by the hierarchical patterns found in nature that repeat all the way down to the molecular level, imbuing material with remarkable strength, durability and color. In the future, we may be able to engineer such properties directly into manufactured materials, and even program some degree of intelligence directly into them, which could make new features and functionality possible.
Those on this year’s list of MIT Technology Review Innovators under 35 list are working towards the ultimate goal of creating architected materials and devices imbued with the ability to make decisions on their own. Read more about their work and what’s needed to help them to succeed in this essay by Julia R. Greer, a materials scientist at the California Institute of Technology.
This essay is part of MIT Technology Review’s 2022 Innovators Under 35 package recognizing the most promising young people working in technology today. See the full list here.
