Significant Link found between Heme Iron, found in Red Meat and other Animal Products, and Type 2 Diabetes Risk

Study Overview: https://www.nature.com/articles/s42255-024-01109-5

Higher intake of heme iron, the type found in red meat and other animal products — as opposed to non-heme iron, found mostly in plant-based foods — was associated with a higher risk of developing type 2 diabetes (T2D) in a new study led by researchers at Harvard T.H. Chan School of Public Health. While the link between heme iron and T2D has been reported previously, the study’s findings more clearly establish and explain the link.

“Compared to prior studies that relied solely on epidemiological data, we integrated multiple layers of information, including epidemiological data, conventional metabolic biomarkers, and cutting-edge metabolomics,” said lead author Fenglei Wang, research associate in the Department of Nutr...

SwRI-led team finds Evidence of Hydration on Asteroid Psyche

Courtesy of SwRI An SwRI-led team used NASA’s Webb telescope, shown in the bottom right corner of this illustration, to confirm the presence of hydrated minerals on the surface of Psyche, a massive and heavily metallic body in the main asteroid belt. These findings suggest a complex history for this interesting asteroid, which many scientists think could be the remnant core of a protoplanet, including impacts with hydrated asteroids.

Webb telescope data indicate a complex history for the metallic asteroid. Using data from NASA’s James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche...

AI Accurately Diagnoses Genetic Condition from Facial Photographs

A Yale School of Medicine team reports in a new study that an artificial intelligence (AI) model was able to reliably diagnose people living with Marfan syndrome from a simple facial photograph.

Marfan syndrome is a genetic disorder, affecting about 1 in 3,000 people, which impacts the body’s connective tissues. “Patients living with Marfan syndrome are usually very tall and thin,” said John Elefteriades, MD, professor of surgery at Yale School of Medicine and senior author of the study. “They have long faces and are prone to spine and joint issues. However, many are not diagnosed.”

Marfan syndrome increases the risk for aortic dissection, where the aorta splits suddenly after becoming enlarged...
