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.
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, even code. All indistinguishable from something written by a person, all instantaneous and free.
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.
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.
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.

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 2035?
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.
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?
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.
