It was literally a back-of-the-envelope idea. Dr. Nima Nassiri had pulled out an envelope to scribble notes on how a bladder transplant could be accomplished in a living person—a surgery that had yet to be performed successfully. About four years later, on May 4, 2025, Nassiri—now 37 and an...

From Dan Lorenc on the malware attack that almost took down the entire internet last year: “There’s a popular compression library that’s used in almost every piece of software. And it had been maintained by one person in his spare time for the last 20 years. And then a couple years ago, somebody just decided to start helping him. They jumped in, fixed a bunch of bugs, and did a lot of great work. And then that first person got tired of working on it. So he handed the whole project over to this other person. It turned out that other person was just a pseudonym and was not a real person. And within six months of getting control of the project, they had put in a carefully orchestrated set of malware that was really hard to detect and no one noticed. And because it was so widely used, the exploit would've basically given that person remote access to any computer running that piece of software, which was basically everything connected to the Internet. But because it was open source and the code was transparent, some random engineer just happened to be running some benchmarks on a weekend. And he noticed that program was a little bit slower than it used to be, and that it was making a weird cryptographic operation to check something. And right before this thing got widely deployed across every device, he dug in, and discovered that there was a backdoor put in. This was the closest thing to a full-blown internet crisis that we’ve ever had. And they still have no idea who did it. It was just an anonymous email account. No one ever traced it back to an individual. And that's the long game. This person spent years just doing good work and earning the communities trust.”

There is a man named Justin Kragt who, for most of his life, believed he was completely alone in the world. He had been abandoned as a toddler outside a theatre in Seoul, South Korea, in 1984, found crying by himself near a police station, which was reportedly common in those years of poverty. A family in the American state of Oregon adopted him, and he grew up assuming he had no blood relatives anywhere on earth. He had even made his peace with it. What he did not know is that on the same day, about a mile away, a little girl was abandoned at a crowded Seoul market. She was around four years old, old enough to tell the police her name, and she had a note tucked in her pocket asking whoever found her to take her to the nearest station. She was adopted separately by another American family and grew up in California, attending pool parties and becoming a cheerleader, carrying a faint, nagging memory of a baby brother she could not place. The two children were siblings. Neither of their adoption records mentioned the other. They grew up roughly six hundred miles apart, both in the same country, both quietly certain they had no biological family. The thing that finally connected them was a home DNA kit. Justin had taken one back in 2014 hoping to find distant cousins. Years later his sister, Renee, took the same test, just to check her health history. The result came back and listed a sibling. A brother. Living in Oregon. She messaged him. His first reaction was to ask if it was a joke. In 2018 they met for the first time at an airport in Oregon, decades after a single afternoon in Seoul had sent them to opposite sides of an ocean without either of them ever knowing the other was there. They met on the fifteenth of September, which happened to be Justin’s birthday.
