How tough can a microscopic animal be? Dr. Chris Mason, Professor of Physiology and Biophysics at Cornell University explains that tardigrades, microscopic “water bears” found in soils around the world, can survive heavy radiation and the vacuum of space. Scientists have also taken genes from tardigrades and put them into human cells to recreate that radiation resistance. #Science #Biology #ScienceFacts #ScienceTok #PopularScience
