NASA Redirects an Asteroid
65 million years ago an asteroid struck the earth. In the ensuing planetary darkness, the dinosaurs went extinct. But the dinosaurs didn’t have a space program! Now we can spot incoming asteroids with steadily improving confidence. If we see one on a collision course with the Earth, we know from the movies that the solution is to nuke it...Right? Actually, NASA has a better idea. If you can just nudge an asteroid slightly off its current path, maybe 25 or 50 years before it hits us, it won’t hit the earth. ...

How They Found the Shipwreck Endurance
In 1915, British explorer Sir Ernest Shackleton’s historic expedition to Antarctica stalled when floating ice trapped, crushed, and finally sank his ship, Endurance. Shackleton’s men survived 21 months on the ice, alone and freezing, and became one of the most incredible adventure stories ever recorded. The ship itself, Endurance, was not seen again for 106 years. Every attempt to find it wound up thwarted by exactly the same enemy: crushing sheets of pack ice. Finally, in 2022, an international team of exp...

Deepfakes: Big Tech Fights Back
Deepfakes, those computer-generated videos of well-known people saying things they never actually said, strike a lot of experts as terrifying. If we can’t even trust videos we see online, how does democracy stand a chance? As photo- and video-manipulation apps get cheaper and better, the rise of fake Obamas, Trumps, and Ukrainian presidents seemed unstoppable. But then a coalition of 750 camera, software, news, and social-media companies got together to embrace an ingenious way to shut the deepfakers down—...

The Mars Helicopter That Would Not Die
The star attraction of NASA’s Mars 2020 mission is the Perseverance rover. But bolted to its underside was a stowaway: A tiny, 19-inch helicopter called Ingenuity. She was intended to fly five times on Mars, as a wild experiment to see if anything could fly in Mars’s incredibly thin atmosphere. But as the speed, altitude, length, and usefulness of Ingenuity’s flights improved, her mission was extended indefinitely. Ingenuity is still flying, nearly a year after its original mission was to end—and now, NASA ...

ChatGPT and the End of Writing
In early 2023 ChatGPT blew up the internet. It’s an AI app that can create any piece of writing you ask for. Poems, homework, lyrics, essays, outlines, recipes, interview questions, and even code. All are indistinguishable from something written by a person, all instantaneous and free. In schools, cheaters began cheating immediately. Educators were horrified, calling it the end of homework, college-entrance essays, and even writing skills. New York City schools banned it. Experts called it a potential fact...

Back to Titanic Part 2
In “Back to Titanic” Part 1, David Pogue told of his invitation to join an expedition to visit the wreck of the Titanic in a custom submersible. The company, OceanGate, ordinarily charges $250,000 per person, as part of a new wave in adventure travel. Bad weather immediately canceled the dive that Pogue and the “CBS Sunday Morning” crew were scheduled to join—but the CEO offered a consolation dive to the Grand Banks. The sights were said to include shark breeding grounds, towering underwater cliffs, and ...

Back to Titanic Part 1
The wreck of the Titanic lies about 2.4 miles below sea level. Only five submersibles in the world can carry people to that depth—and four of them have been retired or reassigned. The one remaining sub is something special. First, it holds five people comfortably (instead of two or three uncomfortably). Second, it’s the only one made of carbon fiber. And third, you can buy your way onto it. For $250,000, OceanGate Expeditions will take you down to visit the world’s most famous shipwreck. Deep sea is the new...

The Secret of Baby Carrots
If you type the word “carrot” into Google Images, you get thousands of photos of the classic root vegetable. They’re all full-length, orange, straight, and pointy. Which is a little odd, because 70% of all the carrots we buy are, in fact, baby carrots. Or at least we think they’re baby carrots. Turns out baby carrots aren’t baby at all. And the story of their creation is twisty, uplifting, and super satisfying. It’s all about a California carrot farmer with a distaste for waste—and a frustrated ex-wife. S...

How Impossible Meats Might Save the Earth
People talk about greenhouse-gas emissions from cars, planes, and factories, but one source out-pollutes them all: Cows. Raising meat animals like cows generates more methane than the entire fossil-fuel industry. So Pat Brown left his job as a Stanford biochemistry professor to dedicate his life to fixing the problem. He vowed to create perfect meat replicas using only plant ingredients. His Impossible Burger is already a megahit—but can he be serious about replacing all beef, pork, chicken, and fish by 203...

The Man Who Stopped the Spammers
By the year 2000, the internet was already becoming a cesspool. The bad guys used software bots to sign up for millions of fake email accounts—for sending out spam. PhD student Luis Von Ahn stopped them. He invented the CAPTCHA, that website login test where you have to decipher the distorted image of a word. Or you have to find the traffic lights or fire hydrants in a grid of nine blurry photos. Those tests help to keep down the volume of spam, spyware, and misinformation; they advance the clarity of dig...

Where Emoji Come From
Each year, the powers that be endow our phones with about 70 new emoji. For 2022, you’ll be getting a mirror ball, a crutch, an X-ray, coral, a ring buoy, and a bird’s nest—with or without eggs in it. But who ARE the powers that be? Why do they add the emoji they add? Why do we have a blowfish but not a catfish? Why do we have police car, police officer, and judge, but not handcuffs, jail, or prison? In this hilarious episode, you’ll meet the shadowy figures who choose which symbols get added to the perma...

How the Fitbit Knows You're Dreaming
Over the last decade, a group of California scientists has quietly amassed the biggest sleep database ever assembled. It includes every dozing off, every wakeup, every REM-cycle, every chunk of deep sleep, from 15 billion nights of human slumber. It can tell us the average person’s bedtime, whether men or women sleep longer, and which city is really the city that never sleeps. These scientists work at Fitbit—the company that sells fitness bands. And for them, revealing your sleep patterns is only the beginn...

Subtitles for the Blind
You already knew that you can turn on subtitles for your TV show or movie—handy if you’re hearing impaired, or just want to understand the dialogue better. But there’s a corresponding feature for people with low vision: audio description tracks, where an unseen narrator tells you, in real time, what’s happening on the screen. But who creates them, and how, and when? And how do they describe the action during fast dialogue, fast action, sex scenes, and screens full of scrolling credits? A deep dive into a bi...

Chainsaws, Women, and the Cape Town Drought
In 2018, following a historic three-year drought, the water sources in Cape Town, South Africa ran dry. It was the first major city to face Day Zero: when you’d turn on the faucet—and nothing would come out. The town leaders discussed expensive, environmentally disruptive projects like pipelines and desalination plants. But then an environmental nonprofit, the Nature Conservancy, proposed a radically different approach that could win Cape Town 13 billion gallons of water a year, cheaply and perpetually, us...

Where to Live in the Climate-Change Era
It’s the night before Christmas—and many podcasters (and listeners) are nestled all snug in their beds. But we didn’t want to leave you without a dose of witty Pogue science writing. So here, for your listening pleasure, is a free chapter from David Pogue’s latest audio book, “How to Prepare for Climate Change.” This is Chapter 2, “Where to Live.” Obviously, not everyone can afford to move just to escape climate-crisis disasters—yet 40 million Americans do move every year, and an increasing number of them ...

Leap Seconds, Smear Seconds, and the Slowing of the Earth
The earth’s spinning is slowing down. Any clocks pegged to the earth’s rotation are therefore drifting out of alignment with our far more precise atomic clocks—only by a thousandth of a second every 50 years, but that’s still a problem for the computers that run the internet, cellphones, and financial systems. In 1972, scientists began re-aligning atomic clocks with earth-rotation time by inserting a leap second every December 31, or as needed. It seemed like a good idea at the time—until computers started...

How the Cellphone was Born: Three Months of Craziness
In the early 1970s, “mobile phones” were car phones: Permanently installed monstrosities that filled up your trunk with boxes and, in a given city, could handle only 20 calls at a time. Nobody imagined that there’d be a market for handheld, pocketable cellphones; the big phone companies thought the idea was idiotic. But Marty Cooper, now 92, saw a different future for cellular technology—and he had 90 days to make it work. A story of corporate rivalry, Presidential interference…and unquenchable optimism. G...

How Apple and Microsoft Built the Seeing-Eye Phone
Your smartphone can see, hear, and speak—even if you can’t. So it occurred to the engineers at Apple and Microsoft: Can the phone be a talking companion for anyone with low vision, describing what it’s seeing in the world around you? Today, it can. Thanks to some heavy doses of machine learning and augmented reality, these companies’ apps can identify things, scenes, money, colors, text, and even people (“30-year-old man with brown hair, smiling, holding a laptop—probably Stuart”)—and then speak, in words,...

Who Makes the Fake Languages for Hollywood?
The first time you heard “Star Trek” characters speak Klingon, or the “Game of Thrones” characters speaking Dothraki and High Valyrian, you might have assumed that the actors were just speaking a few words of gibberish, created by some screenwriter to sound authentic. But these are complete languages, with vocabulary, syntax, grammar, and even made-up histories. There’s only one person on the planet whose full-time job is creating them—and these days, he’s swamped with requests. No doubt about it: Conlangs ...

How NASA's $2 Billion Rover Landed Itself on Mars: "Seven Minutes of Terror"
Perseverance, NASA's latest Mars rover, is a one-ton, $2 billion marvel. The plan was for it to enter the Mars atmosphere going 12,000 miles an hour. The problem: How do you slow it down enough to set it down gently on the surface? You can't use retro rockets, because they'd stir up so much dust, the rover’s cameras and instruments would be ruined. You can’t deliver Perseverance inside a larger spaceship, because the rover wouldn’t be able to drive out of the landing crater. You can’t even control the desce...

Tornado Alley is Shifting Eastward—and We're Not Ready
Tornadoes are nasty and dangerous. They appear and disappear so fast, there’s usually no time for evacuation—and the United States gets 75% of all the world’s tornadoes, about 1,300 of them a year. They occur all year ‘round, in all 50 states, but the biggest swarm forms in Tornado Alley, in the southern Plains states like Texas, Oklahoma, Kansas, and Nebraska. In 2018, storm chaser and meteorologist Victor Gensini made a startling discovery: Tornado Alley has been shifting eastward. Their growing frequency...

Audio Deepfakes and the End of Trust
The media is plenty freaked out about “deepfakes”: Computer-generated videos of famous people saying things they never actually said. But only the video is faked; the audio parts, the voices of those fake celebrities, were supplied by human impersonators. But now, software exists to mimic anyone’s voice, opening a Pandora’s Box of fraud, deception, and what one expert calls “the end of trust.” Fortunately, a new coalition of 60 news organizations and software companies think they have a way to shut down the...

How We Almost Blew the Vaccine
It may seem as though we got the Pfizer and Moderna COVID vaccines incredibly quickly. But Hungarian biochemist Katalin Karikó had been trying to make mRNA vaccines work for 30 years while fighting scientific gatekeepers who thought her idea was absurd. Her grants were denied, her papers rejected, her speaking invitations withdrawn; eventually, the University of Pennsylvania demoted her. But she still refused to quit, and in 2005, she and collaborator Drew Weissman cracked the code. They figured out how mRN...

What Happened to the Mosquitoes in Fresno?
Mosquitoes are the deadliest creatures on earth; they kill 500,000 people a year—and as the planet warms, more species are spreading North from the tropics. In 2013, a nasty new type, called Aedes Aegypti, arrived in Fresno, California. But traditional tactics, like spraying insecticide and genetic modification, have ugly side effects. So one genius programmer from Google thought up a better solution—that doesn’t involve insecticide; doesn’t mess around with genes; doesn’t require irradiating; makes it impo...
