Alan Guth was known as the “inventor” of the theory of cosmic inflation, which was able to explain some of the lingering questions about cosmological development that the original big-bang model had left open. Guth’s book “The Inflationary Universe: The Quest for a New Theory of Cosmic Origins” (1997), written for a general audience, discusses the theory.

The history of quantum mechanics is a fundamental part of the history of modern physics. The major chapters of this history begin with the emergence of quantum ideas to explain individual phenomena—blackbody radiation, the photoelectric effect, solar emission spectra—an era called the Old or Older quantum theories.

Virginia Tech scientists found that age-related memory loss stems from molecular changes in the brain. Memory decline might not be just a natural part of aging. Researchers at Virginia Tech have discovered that it is connected to particular molecular changes in the brain, and that fine-tuning these
Interval running condenses the powerful effects of regular running into shorter, high-intensity bursts. Research shows it can improve cardiovascular health, regulate blood sugar, and reduce body fat more effectively than longer steady runs. Just a few short sprints per session can deliver major fitness gains.
Running offers a wide range of advantages for both body and mind. It can protect against disease, improve mood, and even slow down the body’s natural aging process.
Yet about 31% of adults still don’t get enough physical activity, including running. The most common reason people give is simple — they don’t have enough time.
Age Reversal in Primates has been achieved. We have it now.
Anti-aging gene therapy, stem cell rejuvenation, and FOXO3 longevity research take center stage in this episode of Longevity Science News with Emmett Short. This groundbreaking study out of Beijing shows that gene-edited human stem cells—specifically FOXO3-enhanced senescence-resistant mesenchymal progenitor cells (SRCs)—can reverse biological aging in elderly monkeys, restoring youthful brain structure, bone density, immune strength, and even ovarian function. By upgrading the FOXO3 longevity gene, scientists created stem cells that resist cellular senescence, DNA damage, and oxidative stress, effectively making the monkeys younger from the inside out. MRI scans revealed increased cortical thickness and improved memory-related connectivity, while biological age clocks showed a 3–5 year reversal across 54% of tissues—equivalent to 9–15 years of human rejuvenation. Emmett explains how these anti-aging stem cells, epigenetic resets, and exosome-based rejuvenation pathways could revolutionize regenerative medicine, longevity biotech, and future human trials. He also explores the costs, ethics, and long-term implications of turning back time at the cellular level. If you’re passionate about biohacking, gene editing, lifespan extension, or the future of anti-aging science, this is the video for you.
