"Alpha-gal syndrome (AGS) is an allergy to mammalian meat (e.g., pork, beef, and lamb), dairy, and by-products; most cases result from lone star tick bites. … In 2022, up to 450,000 persons in the United States were estimated to be affected. … Based on … blood donor samples collected during 2024–2025 from 10 states, the estimated alpha-gal IgE seroprevalence was 24.0% in the five states with the highest seroprevalence (Arkansas, Kentucky, Missouri, Tennessee, and Virginia).”

When genome editing got going, the ability to trace a mammalian embryo's development to organ generation in exquisite detail was not envisioned. Now it's been accomplished by 2 independent groups.

Your teenager pulling away from you is baked into biology: - At the end of adolescence brain and hormone changes create a bias for action, and the action points away from primary caregivers - They always return, like a small child who walks off, looks back to check everything is safe, then keeps going - Same pattern in other primates, in rodents, in almost every mammalian species - The kid who hits puberty and wants to stay home with you happens, but it is not typical Hormones do not just change the body. They bias us to disperse. @hubermanlab

Scientists discovered one of the most nutrient-dense substances in nature inside an unlikely source: a cockroach. The species, Diploptera punctata, is unusual because it gives birth to live young instead of laying eggs. During development, the embryos are fed a nutrient-rich, milk-like fluid inside the mother’s body. That fluid forms tiny protein crystals in the embryos’ stomachs. When researchers analyzed the crystals, they found a highly concentrated mix of proteins, fats, sugars, and all 9 essential amino acids required in the human diet. The crystals also appear to release energy slowly during digestion, providing a steady supply of nutrients as the embryos grow. The discovery attracted attention after some reports suggested the substance could be more calorie-dense than mammalian milk, including human breast milk. But scientists have not shown that it offers special health benefits for humans, and harvesting it on a large scale would be extremely impractical. Researchers remain interested in the finding because it demonstrates how evolution can produce unexpected biological adaptations even in one of the world’s most disliked insects. Inside this tiny cockroach species, nature developed microscopic nutrient crystals capable of sustaining life during one of the most demanding stages of development.
