As we age, our vision gets blurrier, we form cataracts, and we have a higher risk of glaucoma. But Greenland sharks live for hundreds of years and still maintain healthy, functional eyeballs. So what gives?Host Ira Flatow talks with molecular biologist Dorota Skowronska-Krawczyk, who studies the mechanisms of aging, about <a href="https://www.sciencefriday.com/segments/greenland-shark-eye-aging-jwst/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">what we can learn</a> from these fishy eyeballs and how it could help us.Plus, listener Leon called us with a question: Is it true that the James Webb Space Telescope’s gold-plated mirror is so perfectly flat that if it were the size of the United States, the highest bump would be the size of a baseball? Not quite. Host Flora Lichtman discusses <a href="https://www.sciencefriday.com/segments/greenland-shark-eye-aging-jwst/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">this feat of engineering</a> with JWST project scientist Macarena Garcia Marin.Guests:Dr. Dorota Skowronska-Krawczyk is a molecular biologist and associate professor at the University of California, Irvine.
