A new report warns that a biomarker identified through artificial intelligence can appear accurate in its initial analysis yet still fail when put to its biggest test, typically validation in independent or clinical settings. The finding highlights a growing concern in medical research: AI-driven discoveries may reflect patterns in data rather than real, clinically useful signals, and researchers are being urged to apply stricter validation before trusting such results.

New research indicates that smartwatches become less reliable at estimating calories burned as a user's body fat percentage rises. The finding suggests wearables may systematically misjudge energy expenditure for people with higher body fat, raising questions about how much trust users should place in fitness trackers when managing diet and exercise goals.

Rumana Mehdi, a CURA travel grantee, is carrying out fieldwork in Iraq. The Boston University-affiliated CURA program supports research travel, and her trip highlights ongoing academic field research in the country. Details of her research topic and findings have not yet been made public.

The University of Michigan School of Kinesiology has published a review casting doubt on the accuracy of smartwatch fitness metrics. The findings suggest that common readings such as step counts, heart rate and calorie burn may not be as reliable as users assume. The review is prompting discussion about how much consumers should trust wearable device data for health decisions.
