Weaning reshapes gut microbes to strengthen lifelong immune defenses

According to a team of researchers at Baylor College of Medicine, Tongji University and collaborating institutions, weaning or switching from milk to solid food in early life doesn't just change what babies eat, it helps reprogram the gut's immune defenses to mount faster and stronger responses that can last into adulthood.

Researchers use AI to reveal the true scale of COVID-19 mortality in the US

A machine learning model applied to US death certificate data estimated that over 155,000 COVID-19 deaths were unrecognized between March 2020 and December 2021, suggesting total mortality was about 19% higher than official counts. These undercounted deaths disproportionately affected marginalized populations, including racial minorities, lower-income groups, and residents of the Southern United States.

A healthier thymus predicts longer life and lower cancer and heart disease risk in adults

Imaging-based analysis of over 27,000 adults shows that better thymic health is strongly associated with lower all-cause mortality, reduced lung cancer risk, and improved cardiovascular outcomes. The findings suggest the thymus remains biologically relevant in adulthood, linking immune aging, inflammation, and chronic disease risk, although causality cannot be established.

Menopause may raise women’s Alzheimer risk earlier than doctors once thought

This review argues that women’s higher Alzheimer disease risk may be shaped in part by midlife neuroendocrine aging, especially the menopause transition, rather than by longevity alone. It highlights early menopause, bilateral oophorectomy, vasomotor symptoms, and midlife cognitive changes as underinvestigated but potentially important risk markers, while calling for sex-specific, biomarker-driven prevention strategies.
