Over 50 pharmaceutical companies and biotech firms around the world are now racing to develop vaccines for the coronavirus responsible for COVID-19. Anthony Fauci has said that it might be possible to develop a vaccine in as quickly as 12 to 18 months—but so far, researchers still don’t know which of several approaches might be most safe and effective. Paul Offit, head of the Vaccine Education Center at Children’s Hospital of Philadelphia, says that usually, the standard time to develop a new vaccine and move it through the multiple phases of clinical trials required for FDA approval is measured in years, not months—and despite the need, he worries that shortening the path to a vaccine means that developers will skip critical parts of the testing process.  He joins Ira to talk about the path to a vaccine, and how it might fit in with other parts of the coronavirus response, including community testing and the development of therapeutic drugs to treat patients with COVID-19. Think about the breathtaking images you’ve seen of space—swirling, multicolor galaxies, shining star clusters, and far-off planets. There’s a good chance these photos were taken by the Hubble Space Telescope, which was launched into space 30 years ago today.  Over these decades, Hubble has helped researchers better understand space mysteries, like black holes, warped space, exoplanets, and the expansion of the universe. While it had a rough beginning—it was deployed with a miscalibrated mirror—Hubble has long maintained its status as the premiere telescope.  Joining Ira to celebrate this anniversary is Dr. Jennifer Wiseman, senior project scientist for the Hubble Space Telescope in Greenbelt, Maryland. When you think about how the telephone was invented, you probably think of Alexander Graham Bell. But what about the people who made the telephone effortless to use? For example, you might not have heard of Almon Strowger, a Kansas City undertaker in the late 19th century, who feared he was losing business thanks to poorly connected phone calls—at that time, calls relied on women known as “hello girls,” who manually operated the switches. Strowger’s frustration led him to invent the automatic switching system, which led to modern telephones, transistors, and eventually, computers. His name, however, is still less well-known. Strowger’s story is one of dozens documented in The Alchemy of Us, a new book by materials scientist Ainissa Ramirez, who explores the way human foibles and flaws have shaped our inventions—and how those inventions have changed us. Take, for example, Ruth Belleville, the Englishwoman who literally sold time until accurate clocks were ubiquitous, a story Ramirez uses to describe how industrialization and industrialized time have shaped our sleep. Producer Christie Taylor talks to Ramirez about her unexpected stories of innovation in time, light, photography, and telecommunications—inventions that all helped shape modern culture.   Subscribe to this podcast.
