You order some stuff on the Internet and it shows up three hours later. How could all the things that need to happen to make that happen happen so fast?

In this episode, we break the thermometer watch the mercury spill out as we discover temperature is far stranger than it seems. Five stories that run the gamut from snakes to stars. We start out underwater, with a snake that has evolved a devious trick for keeping warm. Then we hear the tale of a young man whose seemingly simple method of warming up might be the very thing making him cold. And Senior Correspondent Molly Webster blows the lid off the idea that 98.6 degrees Farenheight is a sound marker of health.

Today, Lulu and Latif talk about some of their favorite episodes from Radiolab’s past that hold new power today.

Lulu points to an episode from 2008:

Imagine that you're a composer. Imagine getting the commission to write a song that will allow family members to face the death of a loved one. Well, composer David Lang had to do just that when a hospital in Garches, France, asked him to write music for their morgue, or 'Salle Des Departs.' What do you do? This piece was produced by Jocelyn Gonzales.

And Latif talks about an episode Jad made in 2009. Here’s how we described it back then:

Jad--a brand new father--wonders what's going on inside the head of his baby Amil.

(And don't worry, you don't need kids to enjoy this podcast.) The questions here are big: what is it like to be so brand new to the world? None of us have memories from this time, so how could we possibly ever know? Is it just chaos? Or, is there something more, some understanding from the very beginning? Jad found a development psychologist named Charles Fernyhough to explore some of his questions.

While most of us hear a wall of white noise, squeaks, and squawks....David Rothenberg hears a symphony. He's trained his ear to listen for the music of animals, and he's always looking for chances to join in, with everything from lonely birds to giant whales to swarming cicadas.

In this podcast, David explains his urge to connect and sing along, and helps break down the mysterious life cycle and mating rituals of the periodical cicadas into something we can all relate to.

Love it or hate it, the freedom to say obnoxious and subversive things is the quintessence of what makes America America. But our say-almost-anything approach to free speech is actually relatively recent, and you can trace it back to one guy: a Supreme Court justice named Oliver Wendell Holmes. Even weirder, you can trace it back to one seemingly ordinary 8-month period in Holmes’s life when he seems to have done a logical U-turn on what should be say-able. Why he changed his mind during those 8 months is one of the greatest mysteries in the history of the Supreme Court. (Spoiler: the answer involves anarchists, a house of truth, and a cry for help from a dear friend.) Join us as we investigate why he changed his mind, how that made the country change its mind, and whether it’s now time to change our minds again.

Scientists took about 300 years to lay out the Periodic Table into neat rows and columns. In one hour, we’re going to mess it all up. This episode, we enlist journalists, poets, musicians, and even a physicist to help us tell stories of matter that matters. You’ll never look at that chart the same way again.

As we hit the one year mark since the first U.S. state (California) issued a stay-at-home order to prevent the spread of COVID-19, we put out a call to see if any of you would take us to your secret escape spot and record audio there.

And you astounded us with what you brought in.

In this soundrich, kaleidoscopic episode, we journey around the planet and then, quite literally, beyond it. Listen only if you want a boatload of fresh air, fields of wildflowers, stars, birds, frogs, and a riveting tale involving Isaac Newton and a calm beyond any calm you knew could exist.

Last summer, at a hospital in England, a man in his 70s being treated for complications with cancer tested positive for covid-19. He had lymphoma, and the disease plus his drugs weakened his immune system, making him particularly susceptible to the virus. He wasn’t too bad off, considering, and was sent home. That was Day 1. This is the story of what the doctors witnessed, over the course of his illness: the evolution of covid-19 inside his body. Before their eyes, they get a hint of what might be to come in the pandemic.
