Back in 1963, before the development of the measles, mumps, and rubella (MMR) vaccine, there were 4 million cases of measles every year. It took nearly four decades, but by 2000, enough people had become vaccinated that the measles virus was eliminated in the U.S. But since then, the ranks of unvaccinated people have grown, and the measles virus has been reintroduced into the U.S. This week, Centers for Disease Control and Prevention (CDC) officials report over 600 cases of measles across 22 states. Dr. Saad Omer, professor of Global Health, Epidemiology, and Pediatrics at Emory University joins Ira to answer questions about the current outbreak, including how much worse conditions could get. Every year, hundreds pack Pioneer Works in Brooklyn, New York for “The Universe In Verse,” a live celebration of writing that has found inspiration from science and scientists. This year’s event, which featured readings from guests including Amanda Palmer, David Byrne, and Josh Groban, celebrated the 100th anniversary of Sir Arthur Eddington’s groundbreaking experiment to prove general relativity. The poems also honored Albert Einstein’s legacy in describing the universe as we understand it today. Maria Popova, founder and editor of Brain Pickings, and astrophysicist Janna Levin, both writers as well, join Ira for a conversation about the enduring link between art and science, and share readings of their favorite works. What has big eyes, a bushy tail, and is the only primate to go into hibernation six months out of the year? It’s the fat-tailed dwarf lemur, an endangered species endemic to the island of Madagascar. During their hibernation period, the lemurs enter a state of torpor, which essentially disables the animals’ internal thermostat. It turns out we humans possess the same gene that is activated when the lemur initiates torpor—we just don’t know how to activate it. Science Friday video producer Luke Groskin traveled to the only captive colony of dwarf lemurs in the world outside of Madagascar, the Duke Lemur Center in North Carolina, to investigate the sleeping cuties’ hibernation habits—and how they could apply to humans.
