If Jeff Bezos can drop $10 million to sponsor the Met Gala, he can afford to pay his fair share in taxes.

This MRI study on young kids just exposed something terrifying: They scanned the brains of 60 children aged 3–5 — including 5-year-old Rose — and found interactive screen time is causing measurable loss of white matter in their developing brains. Even just 2 hours a day is linked to impaired neural connectivity, language, and literacy development. Professor Mike Nagel (neuroscientist and father) said his first reaction was simply: “Wow… I was not anticipating seeing anything like that.” We’re physically changing children’s brains before they even start school — and the damage is visible on scans. This one actually unsettled me. I’ve always suspected too much screen time was bad, but seeing real white matter loss in toddlers hits different. Parents of little ones — has this kind of research changed how much screen time you allow?

Fernando Mendoza stayed home with his mom to celebrate being selected first overall in the NFL Draft instead of attending the in-person celebration She has multiple sclerosis, causing her to be in a wheelchair. This is what matters. Not trophies—family.

What in the world did we just see! The 2 hour marathon barrier has been broken. Three guys went under the old world record... Sabastian Sawe just ran 1:59:30 with crazy negative splits, closing the last half in 59:01....faster than the American Record in the half. One of the most mind blowing performances we've seen. How did we get here? Every breakthrough is a mixture of belief and progress. It takes folks daring to see what's possible, surrounding themselves with a quality team and doing the work to give themselves a shot. You've got to bet on yourself in a big way. When asked whether he believed he could run a sub-2-hour marathon before the race, Sawe answered with one word: "Yes." Let's get the obvious out of the way. Performance enhancing drugs are the legitimate question mark to every breakthrough. So Sawe did as much as he could about taking that off the table. He and his team asked to be tested all the time. His sponsor put up 50K to the Athlete Integrity Unit. The tests are run independently, no advance notice. Over a 2 month stretch, he went through 25 drug tests. There's always a doubt. There has to be given what we know. Hopefully there's transparency in the results. But hats off to Sawe for addressing it: "I want to prove that I am clean when I set foot at the start line." But how'd we actually get here where two guys went sub 2 in the same race? 1. Shoe tech We've had a revolution in shoe technology that boosts running economy. For years shoe companies said their shoe would make you faster and was mostly marketing. Until 2016, when it actually did. Initial research showed a 3-4% saving in economy, while subsequent work has shown it's highly variable. Now, it's a matching game. Find the perfect shoe for your form and you can get a big boost. Normally, it takes years of lots of miles and strength training to boost economy. But now we get that instant boost that not only helps boost performance but often leaves us feeling less beat up in the later stages of the marathon. So we get a little bit less hitting of the wall... 2. The fuel For a long time, fueling was limited by biology. You can only take in and process so much. Then in the 2000s, researchers found if we mixed sugars, we can boost intake because they're processed differently. Then recently, Maurten found if you use a hydrxogel, you boost utilization without GI distress anymore. We've gone from pushing 60g/hr to 120g/hr in a few decades. Again...less bonking. 3. Depth A few decades ago, you spent your career racing on the track and then once your speed started to fade a bit you went to the marathon. Now, many skip right to the marathon. That's where the money is. And with the economy boost from the shoes, you can make that jump quickly. More depth of talent means more competitors in their prime pushing barriers. 4. Belief Even with the shoes and tech, a few years ago sub 2 hours seemed a long way off, until Kipchoge pushed that barrier in a series of time trials. Yes, they weren't official races and had contrived pacing. But it absolutely shifted everyone's thinking on what is possible. A generation of runners saw Kipchoge go for it. Our prediction of what is possible changed. It's mind blowing how far we've come in such a short time. What once seemed decades away, just got smashed twice in the same race. Hats off to Sawe, especially for addressing the scourge of doping and showing folks what is possible with a lot of hard work, some crazy belief, and some fortuitous advances.

These are the Twitter/X accounts with the most engagement so far in 2026. I suppose I had some intuition for how bad it was, but jeez, this is what you get when the ecosystem is broken.
