Snake oil
According to the experts that we spoke to, the death, which followed an intravenous NAD⁺ infusion that went catastrophically wrong, underscores the risks of unproven treatments and the need for rigorous longevity medicine. Earlier this week, Elizabeth Baron, a 27-year-old woman from New York City, died after receiving an intravenous infusion at a local “wellness...
The kidney
Autophagy, which increases in younger mice under toxic stress, does not increase in older mice and leaves them susceptible to acute kidney injury (AKI). Increasing autophagic flux by targeting a key molecule, transcription factor EB (TFEB), alleviates some of this damage. An acute disease with lasting effects AKI is a rapidly developing condition that causes...
DNA clock
A recent review discusses the development of biological aging clocks, their capabilities and limitations, the discoveries they enabled, and possible future developments in this area [1]. How do we measure aging? Developments in science and technology have allowed researchers to move beyond speculation and philosophical debates about aging to study its molecular underpinnings and the...
Situps
A new study suggests that regular planned exercise, not just being generally active, protects against certain aspects of muscle aging [1]. Are trained muscles younger? With age, skeletal muscles lose strength, metabolic flexibility, and mitochondrial capacity. While regular exercise slows many aspects of functional aging [2], just how deeply training affects the molecular state of...
Gabriel Cian Interview
In this follow-up interview, we speak with Gabriel Cian about how the 2060 ecosystem has evolved since last year’s Forum, what he learned from the first edition, and how he is thinking about investment, scientific credibility, health optimization, policy, and the future of longevity in Europe. Last year, we spoke about your path from software...
Human liver
Researchers have described a method of using exosomes derived from mesenchymal stem cells (MSCs) to fight harmful metabolic changes in the liver. Another look at exosomes This is far from the first attempt at using MSC-derived exosomes, particularly exosomes derived from MSCs originally taken from human umbilical cord tissue (HucMDEs derived from HucMSCs), to treat...
