According to a new study using a mouse model of a rare disease, transplanted immune cells donate their mitochondria to neighboring donor cells, improving energy production and rescuing function [1]. Here, have some mitochondria Friedreich’s ataxia is a rare genetic disease in which deficiency in the protein frataxin impairs mitochondrial energy production, especially in energy-hungry...

In a pilot study, patients engaging in intermittent fasting demonstrated improvements in Huntington's disease, a neurodegenerative condition currently considered untreatable. However, the study’s size and limitations call for more research [1]. Fast to survive Huntington’s disease is an inherited, progressive neurodegenerative disorder caused by an expansion of a repeated DNA sequence in the HTT gene,...

In a new study, thymic tissue implanted in the spleen improved immune responses against viruses and tumors and reversed age-related thymic involution in mice [1]. Growing one organ inside another The thymus is a small but crucial organ, where T cells mature to become the backbone of our adaptive immune system. There, they acquire their...

Six different aging clocks detected younger blood protein profiles in patients taking the experimental lung-fibrosis drug rentosertib. This suggests possible anti-aging effects, but separating those from the narrower benefits of treating fibrosis remains a challenge [1]. The AI-developed drug Many drugs developed for particular diseases act on aging-related biological processes. That creates an opportunity: a...

In a new study, semaglutide given late in life increased median lifespan in female mice by more than 12% and improved various health markers. Semaglutide’s effect possibly went beyond caloric restriction [1]. Old mice, new drugs GLP-1 receptor agonists, which act on a hormone that regulates insulin secretion and appetite, have revolutionized obesity treatment, showing...

Michael Snyder, Director of the Center for Genomics and Personalized Medicine at Stanford University, is obsessed with health-tracking wearables. During our interview, he wore four wrist-worn devices – watches and bands – and two rings. He is convinced that these small but powerful gadgets will help drive the transition from today’s “sickcare” to true healthcare,...
