The “species” category is almost certainly the best known of all the taxonomic classifications that biologists use to organize life’s vast diversity. It’s a linchpin of both conservation policy and evolutionary theory, though in practice biologists have struggled to find a definition that works across the natural world. In this episode, Kevin de Queiroz, a… Continue reading Why Is It So Hard to Define a Species?
Peak Waste: Feds Set Record for Improper Payments
In 2021, near the peak of the coronavirus pandemic, investigators tailed a Jeep Cherokee stolen from an airport Avis to a New York City apartment they called a “fraud factory” – no furniture, just an air mattress, a computer, stacks of loan and tax forms, and a shredder.

Nope—It’s Never Aliens
I grew up believing in UFOs. I watched every TV show about aliens, spaceships, and aliens in spaceships.

How the Human Brain Contends With the Strangeness of Zero
At first, zero caused confusion. “Its ability to represent ‘nothing’ and enable complex mathematical operations challenged deeply ingrained theological and philosophical ideas,” Nieder said. Particularly due to the influence of the church, philosophers and theologians associated “nothing” with chaos and disorder and were disinclined to accept it. Many even feared it, considering it “the devil’s… Continue reading How the Human Brain Contends With the Strangeness of Zero
