MIT researchers developed a non-invasive imaging technique that enables laser light to penetrate deeper into living tissue, capturing sharper images of cells. This could help clinical biologists study disease progression and develop new medicines.
A new study highlights a hidden challenge of using AI in medical imaging research — the phenomenon of highly accurate yet potentially misleading results known as "shortcut learning." The researchers analyzed thousands of knee X-rays and found that AI models can "predict" unrelated and implausible traits such as whether patients abstained from eating refried beans or beer. While these predictions have no medical basis, the models achieved high levels of accuracy by exploiting subtle and unintended patterns in the data.
The Herbert Wertheim School of Public Health and Human Longevity Science at University of California San Diego is creating programs to improve safety for all roadway users, including drivers, pedestrians and cyclists. With support from two grants from the California Office of Traffic Safety through the NHTSA, the school is developing an educational program geared towards Native American youth as well as new online courses to improve older driver safety.
