Elon Musk and Twitter go to court


The news: According to new research, radiologists, aided by an AI, diagnose breast cancer more successfully than when working alone. That same AI also yields more accurate results in the hands of a radiologist than when operating solo.

Why it matters: 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, depending on whether it’s used alone or to help a human expert. help out. The process meant that nearly three-quarters of screening exams did not require radiologist review, which could help reduce 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 real clinics with real patients. The hope is that such systems could save lives in the future by detecting cancers that doctors miss, freeing up radiologists to see more patients and lightening the burden in places where there is a dire shortage of specialists.

Materials with nanoscale components will change what is possible

Materials scientists have long been fascinated by the hierarchical patterns in nature that repeat down to the molecular level, giving materials remarkable strength, durability and color. In the future, we may be able to construct such properties directly in manufactured materials and even program a degree of intelligence directly into them, which could enable new features and functionality.

Those on this year’s list of MIT Technology Review Innovators under 35 are working toward the ultimate goal of creating architectural materials and devices imbued with the ability to make decisions for themselves. Learn about their work and what it takes to help them 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, which recognizes the most promising young people working in technology today. View the full list here.
