When protective lipids decline, health risks increase

Researchers at Weill Cornell Medicine found that decreased ceramide levels in blood vessels can cause chronic illnesses. Ceramides regulate blood vessel tone and prevent blood clots, but low levels increase inflammation, high blood pressure, and glucose levels, leading to cardiometabolic conditions.

AI that measures its own uncertainty could improve liver cancer detection

A new editorial in Oncotarget discusses how artificial intelligence can improve liver imaging by recognizing when it might be wrong. The approach, called 'uncertainty quantification,' helps clinicians better detect liver cancer and other diseases by pointing out areas in medical scans that need a second look.
