Salvia Leads Chemists on a Psychedelic Existential Journey Jan 08, 2018

Show notes

On August 2, synthetic organic chemist Ryan Shenvi stood before 300 people at the Natural Products and Bioactive Compounds conference and told them something he knew was sacrilegious: He’d synthesized salvinorin A, the active ingredient in the wildly intense hallucinogen salvia, and he hadn’t just copied a molecule, as synthetic organic chemists are wont to do. He had subtly changed its molecular structure, as synthetic organic chemists are not wont to do.

Let's Do the Physics of the Giant Driving Cities in Mortal Engines Jan 08, 2018

Show notes

Next December, there'll be a new entrant into the end-of-year, blockbuster science fiction movie category: the Peter Jackson film Mortal Engines. A teaser trailer for it dropped just before the holidays, and there's really only one thing you need to know about it. Driving cities. Driving cities! Now, I know the movie is based on a book series, which probably has a lot of detail about these giant ambulatory dwellings. But I like to try and see what I can figure out just from the trailer itself.

How You Could Get an Early Warning for the Next Big Quake Jan 05, 2018

Show notes

At 2:39 am Thursday morning, millions of Bay Area residents from Sacramento to San Jose were shaken awake by the rolling tremble of a 4.4 magnitude earthquake. The eight-mile deep tremor struck along the Hayward fault, two miles southeast of Berkeley. From my apartment just 20 blocks from the epicenter, I woke with the rest of the neighborhood and rode out the wake from bed for about 10 seconds.

A Clever New Robotic 'Muscle' Seriously Lifts, Bro Jan 05, 2018

Show notes

Oh, the poor humanoid robots. After decades of development, they're still less sprinty Terminator and more … octogenarian on sedatives. While these robots may look like us, they aren’t built like us—electric motors in their joints drive their herky-jerky movements, whereas our muscles give us more precise control over our bodies. Well, unless we’re on sedatives.

Why the Bomb Cyclone Hitting the East Coast Is So Unusual Jan 04, 2018

Show notes

Now, the first thing you should know about a bomb cyclone is it’s just a name—and unlike a sharknado, it’s not a literal one. The very real scientific term describes a storm that suddenly intensifies following a rapid drop in atmospheric pressure. Bombing out, or “bombogenesis,” is when a cyclone’s central pressure drops 24 millibars or more in 24 hours, bringing furious winds that can quickly create blizzard conditions and coastal flooding.

The Physics of Plastic Sheets … and Their Invisible Force Fields? Jan 04, 2018

Show notes

When you wander around the internet, sometimes you can find some crazy stuff. Check this out: It's an old account of a weird phenomena created by giant plastic sheets at 3M Corporation. In short, these fast-moving, electrically-charged plastic sheets created some type of effect that prevented humans from passing through an invisible wall. It sounds a lot like some type of force field, right? I'm honestly skeptical that this is real, but let's just assume that it actually happened.

The Most-Read WIRED Science Stories of 2017 Jan 02, 2018

Show notes

Back at the start of the summer, WIRED science writer Megan Molteni dropped a bomb: "The Tick That Gives People Meat Allergies Is Spreading." The story went viral, (probably because we published the the words "meat allergies" during peak grilling season), but the piece was more than a clicky headline: Molteni dove deep into the molecular science behind what causes the adverse reaction.

Health Care Is Hemorrhaging Data. AI Is Here to Help Jan 01, 2018

Show notes

Artificial intelligence used to mean something. Now, everything has AI. That app that delivers you late-night egg rolls? AI. The chatbot that pops up when you’re buying new kicks? AI. Tweets, stories, posts in your feed, the search results you return, even the people you swipe right or left; artificial intelligence had an invisible hand in what (and who) you see on the internet.
