Samsung Galaxy Z Fold8 Ultra Hands-On
Apple’s foldable has soaked up most of the oxygen this season, which is convenient if you already live inside iOS. Anyone who would rather keep Android, DeX, and three live apps on one slab still has a clearer answer: Samsung’s Galaxy Z Fold8 Ultra, priced at $1,799.99 (was $2,100), the first book-style Fold to carry the Ultra badge and the first to pair that badge with a camera and battery that finally match the price.

Max vs 100 Go-Kart Race
Red Bull staged Max vs 100 on Wednesday, September 16, 2026, as the largest go-kart race ever run, lining 101 identical karts on a purpose-built layout at Silverstone designed by race director David Terrien. Max Verstappen started 101st with a simple brief: catch and pass every driver ahead of him inside 30 laps or 75 minutes. Once the rear of his kart drew level with the front of another, that driver was out for good. The 100 people in front of him were athletes, content creators, streamers, journalists, and fans, most of whom had seen the track only in Tuesday practice plus one qualifying lap. Dutch Formula One journalist Jacky Martens took pole. YouTuber Zac Alsop and Red Bull Ford Powertrains technician Lewis Osler sat near the front with him.

iPhone 18 Pro Teardown
REWA Technology posted one of the first teardown videos of the iPhone 18 Pro hours after the phone reached stores, working on the physical SIM version rather than the eSIM-only models sold in the United States and a few other markets. That choice matters because the SIM tray model carries a slightly smaller battery than the versions without a tray. The unit they opened weighs 209.3 grams and looks almost identical on the outside to last year’s phone, so older cases still snap on without trouble.

Leica A Camera 100-Year-Old restoration
Leica Camera posted a nearly two-and-a-half-hour film called Repairing a 100 Year Old Camera, and it does exactly what the title says. A technician in the company’s own workshop takes apart a Leica I that has lived with the Leitz family since the mid-1920s, finds the cloth that used to keep light out, and puts the whole machine back into working order. There is no voiceover, no score, and almost no cutting. You hear screws, brushes, and the faint click of a shutter that has been doing the same job for a century.

Teaching Google Fruit Fly Brain to Play Balatro
Google Research and HHMI Janelia’s FlyEM team released MaleCNS v1.0 earlier this month, a complete wiring diagram of an adult male fruit fly’s brain and ventral nerve cord. More than 166,000 neurons and about 125 million synapses sit in that public map, rebuilt from electron-microscope slices of a real Drosophila with machine-learning reconstruction. Hobbyists spent the next two weeks pointing those cells at DOOM, Beat Saber, Minecraft, a Rubik’s Cube, crypto tickers, and a parallel-parking drill. Then someone pointed them at Jimbo from Balatro.
