University of Wisconsin–Madison researchers are warning that artificial intelligence tools gaining popularity in the fields of genetics and medicine can lead to flawed conclusions about the connection between genes and physical characteristics, including risk factors for diseases like diabetes.

A new study of more than 1,000 adults, average age 33, found that meeting recommended physical activity guidelines isn't enough to counteract the 60-plus hours per week they spend sitting. To reduce heart disease risk and prevent accelerated aging, they need to sit less and work out harder.

Two researchers from The University of Texas at Dallas’ Center for Vital Longevity have received a five-year grant from the National Institutes of Health to expand their study of brain structure, function and cognition across time through the use of a 7-Tesla magnetic resonance scanner.

Psychology professors Dr. Kristen Kennedy and Dr. Karen Rodrigue in the School of Behavioral and Brain Sciences were awarded $3.7 million from the NIH’s National Institute on Aging to extend their Dallas Area Longitudinal Lifespan Aging Study to include a fourth and fifth wave of data collection, which will allow them to follow study participants across 14 years.

Using this 24-ton MRI machine that has the ability to image less than a millimeter of tissue, the researchers will be able to explore the chemical metabolites of the brain’s tissue.
