Biohacker Bryan Johnson spotlights autoimmune gastritis

Entrepreneur Bryan Johnson revealed he has autoimmune gastritis, a hard-to-diagnose autoimmune attack on stomach acid–producing cells that can cause iron deficiency, anemia, and increased cancer risk. Medical experts urge more biopsies for iron-deficient patients to catch the condition, while Johnson weighs treatment options including iron supplementation and experimental approaches like CAR-T therapy, underscoring that even intense health optimization can’t fully shield someone from disease.

Iron absorption linked to autoimmune gastritis: Bryan Johnson's warning

Biohacker Bryan Johnson says he has autoimmune gastritis, which reduces stomach acid and iron absorption, explaining years of low ferritin. After oral iron failed to raise his iron stores, he’s opted for iron infusions and regular ferritin monitoring; the article notes that about 1 in 4 Americans may have insufficient iron intake or absorption, highlighting a broader public-health issue.

Five Under-the-Radar Lab Tests Women 40+ Should Request

Dr. Jennifer Roelands argues that standard wellness panels miss key midlife risks for women and recommends five essential tests: ApoB and Lp(a) for cardiovascular risk; fasting insulin for metabolic health; vitamin D and ferritin for nutrient status; a full thyroid panel (TSH, free T3/T4, antibodies); and free/total testosterone with SHBG to inform treatment decisions. These tests are not usually part of routine panels but enable proactive, precision care during perimenopause; bring this list to your next appointment or order the tests yourself if necessary.

Pigeons use liver macrophages as a magnetic compass

German researchers found iron-rich macrophages in pigeons’ liver detect Earth’s magnetic field and guide navigation; removing these cells disrupts the birds’ sense of direction in cloudy weather, while they can still use the sun on clear days, providing a physical basis for geomagnetic sensing and suggesting multiple cues may guide long-distance navigation.

Exploring In Vivo Electron Tunneling with Ferritin in Various Tissues

A recent paper published in IEEE Transactions on Molecular, Biological and Multi-Scale Communications reviews the evidence of electron tunneling associated with ferritin, a protein involved in iron storage. The study explores the potential role of electron tunneling in various biological systems, including the retina, cochlea, macrophages, glial cells, mitochondria, and magnetosensory systems. The authors hope to raise awareness of this phenomenon and encourage further research into the mechanism of electron tunneling in biological systems that incorporate ferritin.

Low-dose aspirin linked to increased anemia risk in elderly adults.

A retrospective analysis of the ASPREE trial showed that low-dose aspirin use can result in a 20% increase in anemia and a decrease in ferritin levels in older adults. The study suggests that hidden blood loss, not significant bleeding events, may be the primary cause. Older patients taking aspirin should be regularly monitored for hemoglobin levels.
