How I Became a Robot in London—From 5,000 Miles Away Mar 04, 2019

Show notes

I am but a babe, exploring the world for the first time. Wearing a computerized glove, I reach forward in pursuit of a little toy basketball. A robotic arm and hand do the same, mimicking my every move. Slowly I grasp the object, lift it, swing my arm over, and let go, dropping the ball—ploink!—into a plastic cup. I am very, very proud of myself. Applause erupts from the computer in front of me. But this is no American applause here in San Francisco, this is British applause.

Polio Is Nearly Wiped Out—Unless Some Lab Tech Screws Up Feb 28, 2019

Show notes

In 1979, a photographer named Janet Parker got a disease that wasn't supposed to exist anymore. At first she thought she had the flu, but then she kept getting sicker, got a rash, and went to the hospital, where doctors—in disbelief—diagnosed her with smallpox. Just a year earlier, the World Health Organization had declared that "mankind probably had seen its last case of smallpox," according to The New York Times. That should have been true.

Your Weather Tweets Are Showing Your Climate Amnesia Feb 26, 2019

Show notes

Every time someone in a position of power (for example) says that a cold snap in winter proves that climate change is not a thing, a dutiful chorus responds with a familiar refrain: weather is not climate. Weather happens on the scale of days or weeks, over a distance relevant to cities or states. Climate happens over decades, centuries even, to an entire planet.

Doubling Our DNA Building Blocks Could Lead to New Life Forms Feb 25, 2019

Show notes

If you were to boil all of biology down to a simple equation, it would be that DNA makes RNA, which makes proteins, which make every living thing you can see, smell, touch and taste (and a lot of things you can’t). This central dogma of biology, built on strings of Cs, Gs, As, and Ts, has prevailed since Francis Crick, James Watson, and Rosalind Franklin discovered DNA’s double helix 65 years ago.

NASA’s Space Shuttle Rises From the Dead to Power New Vehicles Feb 22, 2019

Show notes

In 2011, the storied Space Shuttle flew for the last time. Three spacecraft survive in retirement as specimens in museums around the country. But the program isn’t dead yet: Many of its parts are popping up as zombie components in spacecraft now in development. Modified left-over Shuttle engines will power NASA’s delayed Space Launch System (SLS), a giant launch vehicle intended for lunar missions and, eventually, Mars.

The Triumphant Rediscovery of the Biggest Bee on Earth Feb 22, 2019

Show notes

For security reasons, I can’t tell you exactly where Clay Bolt rediscovered Wallace’s giant bee. But I can tell you this. With a wingspan of two and a half inches, the goliath is four times bigger than a European honeybee. Very much unlike its honey-manufacturing cousin, it’s got enormous jaws, more like those of the famous stag beetle.

Boaty McBoatface Gears Up for Epic Swim Across the Arctic Feb 21, 2019

Show notes

Boaty McBoatface may be better known for its name than for its oceangoing prowess. But the autonomous underwater vehicle and darling of the internet is headed to greater things: embarking on the longest journey of an AUV by far, with an uninterrupted, roughly 2,000-mile crossing of the Arctic Ocean. The submersible robot got its moniker when it became the consolation prize in a 2016 publicity stunt.

Our Ears Are Unlocking an Era of Aural Data Feb 20, 2019

Show notes

Lisa Muratori is a professor of physical therapy who works with patients suffering from neurological conditions, like Parkinson’s, that might impair their strides. “Gait is important,” she notes—if you’re walking too slowly or unevenly, you’re more liable to have accidents. One tricky part of her practice is helping a patient figure out when their gait is drifting away from a stable pattern.
