More than $21 billion has flowed into longevity. The bigger question now is what actually holds up. Today, Super Human Network and @BCG launch The Longevity Review 2026, a new annual benchmark built to give the field a clearer reference point. The report looks at what research supports, what remains unproven, where capital is flowing, and what people around the world actually understand and want. It combines global research and investment data, BCG consumer research across 19 countries, and perspectives from 14 leading experts, including @davidasinclair, @aubreydegrey, @daveasprey, Andrea Maier and Kayla Barnes-Lentz. So where does longevity actually stand in 2026? Download The Longevity Review 2026 at longevityannual.com.

Psilocybin may be giving scientists a surprising new clue about how skin cells fight aging from the inside out. A study from the University of Lethbridge looked at what happens when human skin cells are exposed to the kind of stress linked to high sugar, excess saturated fat, inflammation, and metabolic damage. The researchers focused on fibroblasts, the cells that help support skin structure, elasticity, and repair. These are some of the cells working behind the scenes to keep skin strong, flexible, and able to recover from everyday wear. When the cells were put under high-sugar and high-fat stress, they started showing signs of premature aging. They became less healthy. More inflammatory signals appeared. Their normal growth cycle became disrupted. Some cells were more likely to stop functioning the way they should, while others had a harder time moving through the repair process. Then researchers added psilocybin. At certain levels, more of the stressed cells survived. Some inflammation-related signals dropped. The cells also showed fewer signs of cellular aging and were better able to keep moving through their normal growth cycle instead of getting stuck under stress. That is the part that makes this study interesting. Aging is not only about wrinkles, gray hair, or what shows up in the mirror. It is also about what happens deep inside the body when cells slowly become less resilient. Over time, cells can become less efficient at dealing with inflammation, oxidative stress, poor metabolic health, and the constant pressure of everyday life. Repair slows down. Damage can build up. The systems that keep tissue healthy may start falling behind. This study adds to a growing conversation around whether psilocybin may have effects that go beyond the brain. Researchers are already studying it in areas connected to mood, depression, anxiety, trauma, and neuroplasticity. But studies like this raise a broader question: could it also help scientists better understand how cells respond to stress throughout the body? That does not mean psilocybin is suddenly an anti-aging cream or a shortcut to younger-looking skin. But it may be another sign that the future of longevity will involve more than supplements, skincare routines, and wearable trackers. It may involve finding new ways to help cells stay adaptable, reduce unnecessary inflammation, recover from stress, and keep doing their job for longer. The next chapter of longevity may be less about chasing youth and more about protecting resilience.

Longevity science is starting to ask a deeper question: What if aging well is about more than keeping the body alive longer? UC Berkeley’s new study is looking at the aging brain through the lens of plasticity, memory, emotion, perception, and overall well-being. The focus is healthy older adults. So much of aging research begins after something has already gone wrong: memory loss, cognitive decline, disease, or diagnosis. This study is more proactive. It looks at whether the brain later in life may still have more room to adapt, reorganize, and stay flexible than we usually assume. Researchers will use MRI scans and follow-up assessments to look for measurable changes in brain structure, brain activity, emotional regulation, social connection, awe, and stress recovery. That makes this less about “anti-aging” in the shallow sense and more about successful aging. Can the brain remain open to change? Can older adults maintain deeper emotional resilience? Can science better understand the biology of aging well before decline begins? That may be one of the most important questions in longevity. Because living longer only matters if the mind, memory, and sense of connection can come with us.

Bryan Johnson approached 5-MeO-DMT as part of a structured longevity experiment, applying the same system he uses for every intervention. His goal has always been simple: identify what creates the biggest impact on human health and performance. His framework looks like this: • Start with fundamentals like sleep, nutrition, and exercise • Layer in advanced protocols like sauna and hyperbaric oxygen • Test high-impact variables that could shift the system 5-MeO entered that system once he saw a gap. It had been explored in other areas, but rarely through a longevity lens, making it worth testing. He treated it as a high-impact variable, asking whether it could create a deeper reset than traditional protocols. What he reported was a full-system shift that stood above his daily optimization stack. That result led to new questions: • How long do the effects last? • Does the benefit fade over time? • Where does this fit in a long-term protocol? For Johnson, the takeaway is clear. Longevity may involve more than steady optimization, with certain interventions capable of rapidly shifting the system in ways traditional methods do not. Source: All In Podcast
