Can you imagine measuring the pulse 📈 and strength 🏋♀️ of tiny beating heart muscles 💓 in space 🌌 for 26 days? We did it and the results are out: As the Smithsonian Institution nicely summarized, our partners Deok-Ho Kim, Devin Mair, and Jonathan Tsui, PhD from John Hopkins University have found that "the heart tissues had grown to beat half as strongly as the Earth-bound samples, and the period between beats stretched to five times longer. Heartbeat irregularity, known as arrhythmia, can cause heart failure, but the tissue’s contractions regained a normal cadence after returning to Earth. On a molecular level, sarcomeres—proteins that aid contraction—were shorter and disordered after space exposure, and cells’ mitochondria, responsible for energy production, had become deformed."

On #thisDayInScience in 1940, Oxford scientists revived Fleming’s work by testing #penicillin on mice with lethal streptococci. Those treated survived, showing penicillin’s remarkable effects. This led to mass production, saving countless lives in WWII and beyond.#Antibiotics Read this post and more on my Typeshare Social Blog: https://lnkd.in/gaDmzsm7

Welcome to 'MicroMiracle,' the episode where we dive into the world of microRNA – the cellular superstars so small, yet so mighty, they've just been celebrated with a 𝐍𝐨𝐛𝐞𝐥 𝐏𝐫𝐢𝐳𝐞 𝐟𝐨𝐫 𝐭𝐡𝐞𝐢𝐫 𝐝𝐢𝐬𝐜𝐨𝐯𝐞𝐫𝐲! Join us as we unravel how these minuscule molecules act like master switches, controlling everything from eye color to disease resistance, right within our cells. We'll break down the science into bite-sized, easy-to-understand pieces, exploring how microRNA impacts our health, influences aging, and even shapes the future of medicine. Whether you're fascinated by biology or just curious about what makes you, tune in to discover why these 'micro' wonders are a 'macro' deal in the grand scheme of life! https://lnkd.in/e9n7ikf4

Humans and naked mole rats are 2 outliers in the largely linear relationship between body size and aging across species (on a log scale). Matt Kaeberlein discusses how body size affects aging in our latest Longevity Science episode: https://lnkd.in/gDQJuqe8
