Thymus health may predict longevity and cancer outcomes

June 01, 2026

由 AI 报道

New research from Mass General Brigham shows that the thymus, a small organ once thought irrelevant in adults, strongly influences lifespan and disease risk. Using AI on CT scans, scientists linked better thymic health to lower risks of death and cancer progression.

Researchers examined CT scans from more than 25,000 adults in a lung cancer screening trial and over 2,500 participants in the Framingham Heart Study. They developed a thymic health score based on the organ's size, structure, and composition. Adults with higher scores had about a 50 percent lower risk of death from any cause, a 63 percent lower risk of cardiovascular death, and a 36 percent lower risk of lung cancer.

Study links rare CGAS gene variant to extended healthspan

Researchers have identified a rare genetic mutation that may help people from long-lived families stay healthier longer by reducing harmful inflammation. The findings were presented at the European Society of Human Genetics conference in Gothenburg.

Frequent midlife TV viewing tied to later brain changes

July 21, 2026 由 AI 报道

A study of roughly 1,700 adults links heavy television viewing in midlife to smaller brain volumes and greater white matter damage decades later. The research suggests the type of sedentary activity matters more than sitting alone. Men showed stronger associations in the findings.

Yale study finds nearly half of older adults improved with age

A Yale University study has found that nearly half of adults age 65 and older showed measurable improvements in cognitive function, physical function, or both over a period of up to 12 years. The research draws on data from more than 11,000 participants and links positive age beliefs to these gains. It challenges the view that aging always involves decline.

Mouse study suggests restoring a youthful gut microbiome may curb age-related liver damage and cancer risk

Researchers reported at Digestive Disease Week (DDW) 2026 that older mice given fecal microbiota transplants made from their own preserved, younger-age stool samples showed less liver inflammation and injury—and none developed liver cancer in the experiment.
