Elon Musk and Twitter head to the courtroom

News: Artificial intelligence-assisted radiologists are more successful in diagnosing breast cancer than when they work alone, according to a new study. The same AI also produces more accurate results in the hands of a radiologist than when working alone.

Why is it important: The large-scale study, published this month in The Lancet Digital Health, is the first to directly compare the performance of AI in diagnosing breast cancer, whether it is used alone or in aid of a human expert. This process meant that nearly three-quarters of screening studies did not need to be reviewed by a radiologist, which could help alleviate a global shortage of specialists.

What happens next: While the results are promising, the next step will be to confirm how well AI works over a long period of time in real clinics with real patients. It is hoped that in the future such systems can save lives by detecting cancers that doctors miss, freeing up radiologists to see more patients, and alleviating the burden in places where there is a severe shortage of specialists.

Materials with nanoscale components will change everything possible

Materials scientists have long been fascinated by the hierarchical structures found in nature, which repeat themselves down to the molecular level, giving materials amazing strength, durability and color. In the future, we may be able to embed 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 under the age of 35 on this year’s MIT Technology Review Innovators list are working toward the ultimate goal of creating architectural materials and devices that make decisions for themselves. Learn more about their work and what it takes to help them succeed in this essay by Julia R. Greer, materials scientist at Caltech.

This essay is part of the MIT Technology Review’s 2022 Innovators Under 35 package, which recognizes the most promising young people working in technology today. See the full list here.
