Hi everybody. I’m writing to you because we are reaching an important moment in our reproduction of Harold Katcher’s seminal study of rats rejuvenation, in which we are only 9 months from starting the injections but we raised 71% of the total cost of the experiment. We already published the article of our 2024 experiment in a peer-reviewed journal (https://journals.tmkarpinski.com/index.php/ejbr/article/view/772), in which we injected the Pig Plasma Extracellular Particles (PPEPs) in young rats to assess a potential acute immunogenicity or toxicity — without any negative effect observed. Nina Torres Zanvettor (cofounder of ICR together with me) and I were interviewed some weeks ago by Eleanor Sheekey in her YouTube channel (https://youtu.be/Q-lS1UMHG1o?si=ImDWycjM8r8-KpyF), as we are trying to spread the word about the experiment and the crowdfunding. We are making the experiment in collaboration with Unicamp university and Dr. Marcelo Mori, a world-class aging scientist. The rats are already aging in the university facility and we are preparing the epigenetic age measurements with Horvath’s foundation (Clock Foundation), but we still have to raise 29% (US$21,000) of the total cost (US$75,000).

We will publish everything (methods, materials and results) immediately, but we need the help of the community too, as we will give back all the information for the community. Could you help us to fund the study? Any amount is important. The link to make a donation is https://www.rejuvenescimento.org/donation. I don’t even consider it precisely a “donation”, but a financial collaboration, as the “donor” would be able to use the information, and maybe they can also use the rejuvenation technology that some day would arise from this research. By the way, if we manage to rejuvenate the rats, we will then try to keep them young as long as we can, in a longevity experiment. Also, if we rejuvenate the rats, we will carry out a safety experiment in a Good Laboratory Practices facility here in Brazil that would allow regulatory approval to try the therapy in human patients who don’t have any other alternative to be kept alive — we expect to be able to carry out those human trials in 2028. So we intend to go all the way to the clinic, if we confirm Katcher’s results.

Anti-ageing and increased mental capacity through cannabis

A low-dose long-term administration of cannabis can not only reverse aging processes in the brain, but also has an anti-aging effect. Researchers from the University Hospital Bonn (UKB) and the University of Bonn together with a team from Hebrew University (Israel) have now been able to show this in mice. They found the key to this in the protein switch mTOR, whose signal strength has an influence on cognitive performance and metabolic processes in the entire organism. The results are now presented in the journal “ACS Pharmacology & Translation Science”

Nanobiotechnology Unveils the Power of Probiotics: A Comprehensive Review on the Synergistic Role of Probiotics and Advanced Nanotechnology in Enhancing Geriatric Health

The geriatric population, comprising ages 65 and above, encounters distinct health obstacles because of physiological changes and heightened vulnerability to diseases. New technologies are being investigated to tackle the intricate health requirements of this population. Recent advancements in probiotics and nanotechnology offer promising strategies to enhance geriatric health by improving nutrient absorption, modulating gut microbiota, and delivering targeted therapeutic agents. Probiotics play a crucial role in maintaining gut homeostasis, reducing inflammation, and supporting metabolic functions. However, challenges such as limited viability and efficacy in harsh gastrointestinal conditions hinder their therapeutic potential. Advanced nanotechnology can overcome these constraints by enhancing the efficacy of probiotics through nano-encapsulation, controlled delivery, and improvement of bioavailability. This review explores the synergistic potential of probiotics and advanced nanotechnology in addressing age-related health concerns. It highlights key developments in probiotic formulations, nano-based delivery systems, and their combined impact on gut health, immunity, and neuroprotection. The convergence of probiotics and nanotechnology represents a novel and transformative approach to promoting healthy aging, paving the way for innovative therapeutic interventions.

Sam Altman’s longevity startup is testing a pill for a younger brain

I’ve just hopped on a video call with the CEO of Retro Biosciences, the Sam Altman-backed longevity company, when I mention it’s quite hot.

Joe Betts-LaCroix takes my passing comment as a cue to muse on the wonders of air conditioning, and how energy and heat were once synonymous — until they weren’t.

As a multi-hyphenate scientist, entrepreneur, and once-inventor of the world’s smallest computer, Betts-LaCroix is excited by paradigm change.

At the helm of what is essentially Altman’s playground for experimenting with pushing the limits of the human lifespan, Betts-LaCroix is hoping to engineer the same shift that air conditioning brought to hot summer days for your brain and body. Ideally, one day, decouple aging from decline and disease.

The experimental memory pill works by clearing out “gunk in the cells” linked to Alzheimer’s and Parkinson’s, Betts-LaCroix said. If the pill works, it will restart stalled autophagy processes in the body, cleaning up damage, “especially in the brain cells,” he said.

In contrast, other new Alzheimer’s drugs, like Eisai’s Leqembi and Eli Lilly’s Kisunla, slow down cognitive decline by flushing out sticky amyloid plaques that are a hallmark of the disease.

Psilocybin delays aging, extends lifespan, new Emory study suggests

As revenues from the anti-aging market — riddled with hope and thousands of supplements — surged past $500 million last year, Emory University researchers identified a compound that actively delays aging in cells and organisms.

A newly published study in Nature Partner Journals’ Aging demonstrates that psilocin, a byproduct of consuming psilocybin, the active ingredient in psychedelic mushrooms, extended the cellular lifespan of human skin and lung cells by more than 50%.

In parallel, researchers also conducted the first long-term in vivo study evaluating the systemic effects of psilocybin in aged mice of 19 months, or the equivalent of 60–65 human years. Results indicated that the mice that received an initial low dose of psilocybin of 5 mg/kg, followed by a monthly high dose of 15 mg/kg for 10 months, had a 30% increase in survival compared to mice who hadn’t received any. These mice also displayed healthier physical features, such as improved fur quality, fewer white hairs and hair regrowth.
