“In this clip, Drs. Levine and Patrick discuss definitions of aging used in science and why biological aging matters to scientists. Dr. Levine shares the hallmarks of aging that help researchers determine someone's biological age, what drives accelerated aging, and what epigenetic modifications such as CpG methylation say about the aging process.”

“Although epigenetic clocks clearly relate to causal aspects of aging, scientists don't know if the clocks are inherently causal. At this time, the clocks are not validated for use as clinical biomarkers for individual use, but rather to look at trends across larger studies.”

“Integral to the benefits associated with time-restricted eating is the concept of fasting physiology, which taps into ancient patterns of defined periods of eating and resting for the purposes of survival.”

“The processes that mediate aging can be likened to those that drive the sharing of digital information – the idea that, as a signal is transmitted, information is lost and must be continually resent to maintain signal integrity.”

“A May 2025 Nature paper showed taurine uptake may fuel aggressive myeloid leukemias in laboratory and mouse models, illustrating how nutrients beneficial to healthy tissues may also feed certain cancers.”

“Thus parents can steward the configuration of their child's microbiome, potentially reducing the risk of asthma, obesity, and other diseases in later life. In this clip, Dr. Eran Elinav discusses the importance of the early childhood period in shaping a healthy microbiome.”

“Many studies suggest that short-chain fatty acids derived from the gut microbiota promote the expansion of T-regulatory cells, maintain gut barrier function, regulate cytokine production, and support immune cell populations.”

“In 1,334 dementia-free adults with a mean age of 84, levels below 25 nanomoles per liter were associated with a 91 percent higher rate of all-cause dementia and a 128 percent higher rate of Alzheimer's dementia over seven years.”

“In this podcast, we discuss and critically analyze a recent headline-grabbing editorial that was published in the Annals of Internal Medicine that reviewed three studies on the topic of multivitamins and chronic disease prevention. We analyze the important shortcomings of the studies and talk about the mechanism.”

“In an observational cohort of 2,545 couples undergoing IVF, women who consumed at least four drinks per week had lower live-birth odds, as did couples in which both partners consumed at least four drinks per week.”
