We Might Not Be Planting the Right Kinds of Forests Dec 30, 2019

Show notes

This story originally appeared on Undark and is part of the Climate Desk collaboration. When most people conjure a forest, they imagine a dense network of trees, their crowns arching high above, with spots of sunshine flashing between the leaves. Some might also think of birdsong and insects, or summon thoughts of thick foliage in the understory, the crunch of leaves or pine needles underfoot, or overgrown trails meandering into the thicket.

Show notes

Flu season is good for no one. The infection kills thousands of people every year, while many more spend days suffering in bed. Kids get infected.

New Tests Use Epigenetics to Guess How Fast You're Aging Dec 24, 2019

Show notes

From the beginning of time, humankind has searched for the secret to a long life. Now science may have found an answer, in the form of molecular augury. The pattern of chemical chains that attach to the DNA in your cells—on-off switches known as epigenetic markers—can reveal how swiftly you are aging, and perhaps even how much longer you will live. While genetic testing might tell you where you came from, epigenetics promises a glimpse into the future.

What a 5,700-Year-Old Piece of Gum Reveals About Its Chewer Dec 23, 2019

Show notes

Nearly 6,000 years ago, in a seaside marshland in what is now southern Denmark, a woman with blue eyes and dark hair and skin popped a piece of chewing gum in her mouth. Not spearmint gum, mind you, but a decidedly less palatable chunk of black-brown pitch, boiled down from the bark of the birch tree. An indispensable tool in her time, birch pitch would solidify as it cooled, so the woman and her comrades would have had to chew it before using it as a sort of superglue for, say, making tools.

Traveling for the Holidays? Here's How to Not Get Sick Dec 20, 2019

Show notes

There’s a cruel irony in the fact that holiday travel tends to coincide with the rise of flu season. Yet more than 47 million Americans are preparing to sit for hours inside a tube in the sky, perhaps near someone with a hacking cough. It sounds like the perfect (infectious) storm. But reaching your destination without collecting microbial stowaways isn’t as daunting as it seems.

Mathematician Terence Tao Cracks a ‘Dangerous’ Problem Dec 19, 2019

Show notes

Experienced mathematicians warn up-and-comers to stay away from the Collatz conjecture. It’s a siren song, they say: Fall under its trance and you may never do meaningful work again. The Collatz conjecture is quite possibly the simplest unsolved problem in mathematics—which is exactly what makes it so treacherously alluring.

Show notes

In the summer of 2014, Markie Miller discovered she'd been drinking toxic coffee. Miller lives in Toledo, Ohio, where fertilizer runoff from farms had caused blooms of toxic cyanobacteria in Lake Erie, her water supply. The city issued an alert at 2 am, but by the time Miller saw it she'd already been sipping her morning java. “I'm like, shit, what did I just expose myself to?” she says.

Forget Earth: In Space, Libertarian Ideas Are Thriving Dec 17, 2019

Show notes

You may have heard the phrase “There ain’t no such thing as a free lunch,” perhaps in conversation with your parents when they wanted you to get a job. Its acronym—TANSTAAFL—pops up in subreddits like r/Anarcho_Capitalism, on sweatshirts from the politically inclined website LibertyManiacs.com, and as a nerdy economics rap on YouTube. Also: For the first eight years of the Libertarian party’s existence, TANSTAAFL was its official slogan.
