What if America Had a Detective Agency for Disasters? Sep 19, 2017

Show notes

The commissions are coming. Hurricane season hasn’t ended, but forensics waits for no one, so the after-action reports on Harvey and Irma have to get started. The relevant agencies—local and perhaps federal, plus maybe some national academies and disaster responders—will all no doubt look at themselves and others to see what went right or wrong.

Antarctica Is Looking for a Few Good Firefighters Sep 18, 2017

Show notes

Antarctica’s summer season is about to begin, which means hundreds of scientists are preparing to head south to conduct experiments on melting glaciers, migrating penguins, and elusive neutrinos. But so, too, will the support staff of the United States Antarctic base, McMurdo Station, population 1,100. McMurdo is a company town of sorts: It has its own air traffic controller, machine shop, IT help desk, dormitory housing, three bars, yoga classes, hiking trails—and fire department.

How Congress Ignored Science and Fueled Antibiotic Resistance Sep 15, 2017

Show notes

The gray clapboard house on the two-lane road in a western suburb of Boston looked, in fall 1974, the way you would expect a comfortable old Massachusetts house full of children to look. It was rambling and tall, made out of a house and a barn butted together. There were other barns out back, down a long gravel drive that stretched to a grove of trees: small sheds and one big building, 200 feet on the long side, painted an iconic barnyard red.

A Patient Gets the New Transgender Surgery She Helped Invent Sep 14, 2017

Show notes

Like many other surgery patients, Hayley Anthony has a daily physical therapy regimen. But unlike other post-ops, the 30-year-old marketing consultant is recovering from a procedure she helped invent. Five months ago, she became one of the first people in the world to have a piece of tissue incised from the cavity of her abdomen and turned into a vagina.

The Serious Physics Behind a Double Pendulum Fidget Spinner Sep 13, 2017

Show notes

I am going to make a prediction. As people start to get bored with their fidget spinners, they are going to start playing with these double pendulum fidget spinners. The normal spinner has a bearing in the center of some object such that you can hold it and spin it—moderately cool, I'll admit. But the double pendulum spinner has two bearings with two moveable arms.

The Science of Fighting Wildfires Gets a Satellite Boost Sep 12, 2017

Show notes

Ash is raining down on the city of Portland. Thousand-degree fireballs are forcing evacuations near Salt Lake City, Seattle, and parts of Northern California. In Missoula, Montana, the sun burns a bloody red even even at high noon. These days, the American West looks less like an Ansel Adams postcard and more like the kingdom of Mordor. Across nine states, nearly 1.5 million acres are on fire. And according to President Trump’s natural resources czar, you can blame it all on the hippies.

Antibiotic-Brined Chicken and Other Bad Ideas From US Farming Sep 11, 2017

Show notes

These days, the only thing more American than apple pie is eating an animal raised on antibiotics. Eighty percent of antibiotics sold in the US go not to human patients, but to the nation’s plate-bound pigs, cows, turkeys, and chickens. As these wonder drugs became a mainstay of modern agriculture, factory farms began churning out another, far less welcome commodity—antibiotic resistant bacteria.

Can a Drone Carry a Full-Grown Human in a Hammock? Sep 08, 2017

Show notes

I have many jobs, but one of my favorite is finding crazy stuff on the internet and using physics to see if it is real or fake. In this case we have a video that shows a drone carrying a human in a hammock. I'll go ahead and say it—this is probably fake. The Physics of Drones You can't tell if the video is real or fake without first understanding the basics of drone flight. In particular, we need to look at the physics of what makes a drone hover.

These Mice Stopped Eating Carbs So You (Maybe) Don't Have To Sep 07, 2017

Show notes

In the ever-more masochistic world of wellness-boosting, pound-shedding diets, the latest trend involves putting your body into a controlled state of starvation known as “ketogenesis,” by cutting out nearly all carbs. If that doesn’t sound like your particular brand of torture, guess what? You’re already on it. Well, at least while you’re sleeping.

'Dream Chaser' Space Plane Hitches a Ride With a Helicopter Sep 06, 2017

Show notes

This morning around 7 am, the engines of a massive, beluga-bodied helicopter cut on with a rumble. The hum harmonized with the reverberations of Edwards Air Force Base, north of Los Angeles. As the Chinook’s two enormous rotor blades started to spin, blasting hot vapor smudged the monochrome stripes of pavement, desert floor, mountain ridge, and sky above NASA’s Armstrong Flight Research Center. And then, finally, the copter began to levitate.
