Extreme Heat, COVID Delta Variant, Poe’s Science. July 2, 2021, Part 1

The Alarming Impacts Of Extreme Heat This week, the Pacific Northwest was hit by a record breaking heat wave, with temperatures rising as high as 116 degrees Fahrenheit in Portland, Oregon. Experts say of all the extreme weather events brought on by climate change and heat waves stand to do the most damage to the environment, infrastructure, and human health. Umair Irfan, staff writer for Vox, joins Ira to share more about the alarming impacts of such extreme heat. Plus, as record-breaking heat becomes more common, air travel may get more difficult. And physicist Rhett Allain explains why airplanes have trouble getting off the ground as the temperature rises.   How Alarmed Should You Be About The Delta Variant? It’s been six months since the first variant of COVID-19 raised alarm bells around the world. Now, a particular variant seems to be spreading rapidly: the Delta variant, first identified in India, and now the dominant strain in many countries, including the United Kingdom. In the United States, the variant makes up more than 20% of cases. South Africa, Australia, Germany, and other countries are re-imposing limits on travel and daily life. And Israel, where more than 60% of people are vaccinated, has reinstated mask requirements. In fact, the World Health Organization is recommending that all fully vaccinated people continue to wear masks as this variant spreads. What does that mean for you? Virologist Angela Rasmussen helps take the temperature of the Delta variant and other COVID-19 news—including promising results on the Novavax vaccine, clues about long-lasting immunity from Pfizer’s mRNA shot, and more.     How Edgar Allan Poe Exposed Scientific Hoaxes—And Perpetrated Them “Leave my loneliness unbroken!—quit the bust above my door!Take thy beak from out my heart, and take thy form from off my door! Quoth the Raven “Nevermore.” When you think of Edgar Allen Poe, poems like “The Raven” and “The Telltale Heart” may pop to mind. But throughout the poet’s life, he was absolutely fascinated by science. His love of subjects like astronomy and physics—along with the tragedy that followed him throughout his life—informed his poems and essays. Through this work, Poe may have also had an impact on science itself. Poe’s scientific life is investigated in the new book, The Reason for the Darkness of the Night: Edgar Allan Poe and the Forging of American Science. In many ways, it explains, Poe’s scientific fascination was a product of its time. He grew up in the early 1800s, which was a time when a widespread thirst for knowledge was beginning to flourish. Poe loved to expose scientific hoaxes, while simultaneously perpetrating them himself. And his self-proclaimed magnum opus, a largely unsuccessful venture, was a nonfiction essay about the nature of the universe, called “Eureka.” Author John Tresch joins Ira to discuss Poe’s life, legacy, and works. Tresch is professor of history of science at the Warburg Institute in the University of London, based in London, England. Subscribe to this podcast.
