Vitamin C and Ferro-Aging: Why a Primate Finding Is Not a Human Longevity Protocol
A 2026 Cell Metabolism study reported that long-term vitamin C treatment changed ferro-aging signatures in aged monkeys. The finding makes ACSL4 an intriguing research target, but it does not establish a human anti-aging supplement protocol.
The Vitamin C Paradox: Why the Viral Ferro-Aging Protocol Could Backfire for Some People
A 2026 Cell Metabolism study found that long-term vitamin C treatment changed ferro-aging signatures in aged cynomolgus monkeys. The result makes ACSL4 an important research target, but it does not establish a human anti-aging protocol and may carry a different risk for people with iron-overload conditions.
2026 Flu Shot Changed All Three Strains After Last Year’s H3N2 Mismatch
The US 2026–2027 flu vaccine changed all three components after last season’s H3N2 subclade K mismatch. The updated shot is designed to improve the match, but winter surveillance and effectiveness studies will determine how well it performs.
Will the 2026 Flu Shot Match This Winter’s Virus? Inside the Global Forecast Trying to Stay Ahead of Influenza
Last season’s dominant H3N2 strain emerged after the flu vaccine had already been selected. For 2026–2027, scientists changed every component. POPR examines the global forecasting system behind the flu shot, the consequences of another mismatch and when real-world evidence will reveal whether this year’s selection worked.
The January Samoa Letter Is the Key to RFK Jr.’s Vaccine Dispute
The dispute over Robert F. Kennedy Jr.'s Samoa trip now turns on a January 2019 letter written before he traveled. The document proposed an MMR-related health-informatics assessment, while HHS says the visit was unrelated to vaccines. The record does not establish criminal wrongdoing or epidemiological causation.
RFK Jr. Said His Samoa Trip Had “Nothing to Do With Vaccines.” His Pre-Trip Letter Proposed an MMR Assessment
A January 2019 letter written before Robert F. Kennedy Jr.'s Samoa trip proposed a health-informatics assessment concerning MMR vaccines. Kennedy later told senators the trip had “nothing to do with vaccines.” The documents establish a factual conflict but do not establish criminal liability or responsibility for Samoa's measles outbreak.
Is AI Safe for Mental Health? Millions Are Using Chatbots, but They Are Not Mental-Health Providers
Millions are using AI chatbots for mental-health support, but they are not automatically therapists or healthcare providers. Verified 2026 research reveals what AI can offer, where sycophancy and crisis failures create risk, what addiction studies actually show, and when HIPAA or 42 CFR Part 2 applies.
What Is Candida auris? Why the Drug-Resistant Fungus Can Hide in Hair Follicles and Keep Spreading Through Hospitals
A 2026 Science study found that Candida auris persists in mouse hair follicles by exposing chitin and triggering an immune response that suppresses normal antifungal skin defenses. The discovery helps explain one biological mechanism behind persistent colonization, the reason this drug-resistant fungus keeps circulating through healthcare networks even when carriers show no symptoms.
Rhonda Patrick Says Creatine Is More Than a Muscle Supplement. What the Brain Research Actually Shows
Dr. Rhonda Patrick has spent years drawing public attention to creatine's possible effects on brain energy, cognition, sleep deprivation and mental health. Human trials now support several parts of that argument, but the evidence does not show that creatine replaces sleep, works as a universal nootropic or should be used at research-level doses without medical context.
Plasmalogens, APOE4 and Alzheimer's: What the New 2026 Brain Lipid Research Actually Shows
Plasmalogens are important membrane lipids that are depleted in Alzheimer's-affected brain tissue, and new 2026 research has linked lower plasmalogen carriage directly to the APOE4 genetic risk variant. However, evidence that oral supplements can rebuild brain white matter, prevent Alzheimer's disease, or reverse neurodegeneration in humans has not yet been established.
Does Ozempic Cause Muscle Loss? What the 2026 Research on GLP-1 Drugs and Lean Mass Actually Shows
Semaglutide, tirzepatide and other incretin-based weight-loss treatments can reduce lean mass along with fat. However, lean mass is not the same thing as skeletal muscle, most of the weight lost is still fat, and new 2026 research shows that strength and muscle health can behave differently from a DXA lean-mass measurement.
Can Scientists Really Rejuvenate Zombie Cells? What the AP2A1 and IU1 Anti-Aging Studies Actually Found
Scientists have discovered new ways to change features associated with cellular aging and improve cellular cleanup systems, but no study has shown that humans can currently rejuvenate zombie cells or dramatically extend lifespan. Two discoveries involving AP2A1 and IU1 are real. The viral story created by combining them is not.
