This jellyfish doesn’t age. 🪸 Meet Turritopsis dohrnii, the “immortal” jellyfish. Under stress, it resets to youth. Scientists are studying how it repairs DNA + resists damage, all clues that could unlock healthier human aging. 🧬 #Longevity #AgingResearch #Healthspan

Exercise changes how we age. 🧬 A new study shows long-term aerobic activity raises betaine, reducing inflammation, slowing senescence & boosting healthspan by blocking TBK1. Movement = medicine. 🔗 https://t.co/Vl9NwOXSG8

🌿 Food as rejuvenation medicine in action: Thymol, the compound that gives thyme its delicious aroma, delayed epigenetic aging in skeletal muscle by about 20% in fast-aging mice. It preserved strength, reduced muscle loss, and boosted cellular cleanup + energy production.

A 36-year study of 120K people found that even a 20% boost in diet quality cut the risk of death by 6–13% from all causes (heart disease, cancer, respiratory illness). Small, steady changes in how you eat can extend healthspan. https://t.co/oPbeXwGzHT

7 days of cold-water immersion (~14 °C, 1 hr/day) boosted autophagy, reduced cell damage signals + improved stress adaptation in a Univ. of Ottawa study. Not just mental toughness—this is biology in action. Would you try it? 👇 #ColdPlunge #Longevity #Autophagy

Check out my conversation with Kara. We touch a little bit on everything, including some exciting things in store for the future
I sat down with Dr. Nir Barzilai, a pioneer in aging research, to explore how centenarians thrive + what the TAME trial reveals about living longer, healthier lives. https://t.co/WCf8aNatv2

Functional medicine has long questioned “inflammaging.” New research shows some traditional groups don’t see rising inflammation with age, yet have low rates of heart disease, diabetes & dementia. Environment, not biology alone, may drive aging. Source: https://t.co/aBCaI7BxVl

🕷️ Tick-borne illnesses are climbing. In May ’25, ERs saw 134 tick bite visits/100k (112 in ’24). June: 130 vs 89 prior year. Beyond Lyme, ticks can spread babesiosis, anaplasmosis, ehrlichiosis, RMSF & alpha-gal. Prevention works—checks & repellents keep you outdoors safe. 🌿
