AI calorie-tracking apps miss up to 345 calories per meal, NIH study reveals

AI calorie-tracking apps are underestimating meals by hundreds of calories, according to new NIH research. A study testing MyFitnessPal, LoseIt!, CalAI and Appediet found calorie underestimation ranging from 250 to 345 calories per meal, with fat content off by about 30 grams. The findings raise questions about the reliability of photo-based calorie tracking for people managing their health or trying to lose weight.

New study reveals 3D genome disruption drives Alzheimer's disease in brain cells

Researchers from Carnegie Mellon University and the University of Pittsburgh discovered that the three-dimensional architecture of the genome is fundamentally altered in specific brain cells of individuals with Alzheimer's disease. Using single-cell technology, spatial tissue mapping, and a novel AI model called Hicformer, the team linked genome folding to gene activity and brain tissue organization, establishing higher-order chromatin reorganization as a primary layer of Alzheimer's pathology.

Dartmouth Study Reveals AI in Healthcare Can Increase Physician Workload With Flawed Responses

A large-scale Dartmouth study analyzing 146,000 patient-doctor conversations found that AI in healthcare often creates more work than it saves. AI-generated responses frequently contain errors and irrelevant details, forcing physicians to spend more time editing AI mistakes than writing messages themselves. However, researchers developed a technique that improves accuracy by 33% and reduces editing by 26%.
