Elon Musk and Twitter are headed to court


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

Why it matters: The large-scale study, published this month in The Lancet Digital Health, is the first to directly compare the performance of artificial intelligence in breast cancer diagnosis, whether it is used on its own or as an aid to a human expert. The process meant that nearly three-quarters of screening studies did not need to be reviewed by radiologists, which could help alleviate a global shortage of specialists.

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

Materials with nanoscale components will change what is possible

Materials scientists have long been fascinated by the hierarchical patterns found in nature that repeat themselves down to the molecular level, imbuing the material with extraordinary 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 enable new features and functionality.

Those on this year’s MIT Technology Review Innovators Under 35 list are working toward the ultimate goal of creating architectural materials and devices imbued with the ability to make autonomous decisions. Read more about their work and what it takes to help them succeed in this essay by Julia R. Greer, materials scientist at the California Institute of Technology.

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