Show notes

Alexander von Humboldt began his working life as a mine inspector for the Prussian government. But in his late twenties, he left his government gig and set off to explore Venezuela, Cuba, Mexico, Colombia, and Peru with botanist Aime Bonpland.

3 Smart Things About Animal-Inspired Robotics Oct 24, 2018

Show notes

1. When turkeys strut, their leg muscles work as shock absorbers to boost energy efficiency. That gam action inspired a prosthetic exoskeleton for humans: The lightweight contraption is outfitted with a spring and clutch that take the impact off the user’s calf muscle. In experiments, a person wearing the braces while walking expended 10 percent less energy. 2. Though it has a brain, the lamprey—an eel-like beast—doesn’t need it to wiggle about the deep.

Science Isn't About 'the Truth'—It's About Building Models Oct 23, 2018

Show notes

You might think you can just leave the science stuff to scientists—but you can't.

Here are the key aspects of science that everyone needs to know. Yes, this is for you.

Scientists Help Robots 'Evolve.' Weirdness Ensues Oct 23, 2018

Show notes

Evolution is a trip. On the one hand, it’s a seemingly simple mechanism—those best fitted to their environment have more babies, while less fit individuals don’t reproduce as much, and their genes filter out of the system. But on the other hand (or paw or claw or talon), it has given rise to an astounding array of organisms. Some animals fly with feathered wings, others with membranes stretched between fingers. Some run on two legs, others four.

DNA Tests Could Help Docs Detect Infectious Diseases Faster Oct 22, 2018

Show notes

Early last spring, as flu season hit its peak, a woman checked into a Houston hospital with all the familiar symptoms: fever, headache, a grating cough. A chest x-ray revealed an infection engulfing her lungs. Doctors hooked her up to an antibiotic drip, collected blood to be processed and cultured in the hospital’s lab, and shipped one of the tubes overnight to a small, stealthy startup in Redwood City, California, called Karius.

Show notes

Imagine for a second that you’re a crab, and a fellow crustacean called a mantis shrimp has decided to make you its lunch. The truth is, it’s not worth struggling.

Show notes

Last Wednesday, Hurricane Michael slammed into the Florida Panhandle at 155 miles per hour, flattening neighborhoods, turning subdivisions into rubble, and plunging the coast into darkness. On Friday, Trevor Lewis packed up two trucks with crowbars, chainsaws, sledgehammers, ropes, walkie talkies, and five other guys from Cocoa Beach, where he lives on the east side of the state.

Delivery drones are real and they’re operating on a national level, but they’re not dropping off impulse purchases, and some of the most important applications are not in the United States. Zipline, a Bay Area startup, inked a deal with the government of Rwanda in 2016 and now uses small, autonomous planes to deliver medical supplies, and in particular blood, to rural communities across the African country.

The scientist has made a career of replacing invasive, painful, and dangerous procedures with simple, cheap tests that can be performed almost anywhere. Just this year, a blood panel he developed to detect genetic birth defects has been taken by more than three million women, replacing the need for amniocentesis and giant, uterus-puncturing needles.
