Scientists put kids through 100 hours of reading, then scanned their brains. New wiring had physically grown inside the language regions. Communication between brain areas sped up by a factor of 10. Kids who didn't read showed zero change. That was a 2009 Carnegie Mellon study. It gets wilder. In 2013, Emory University scanned 19 students every morning for 19 straight days while they read one novel chapter each night. Mornings after reading, the brain areas responsible for understanding other people's emotions lit up with new connections. So did the region that processes physical sensation. Their brains were simulating what the characters felt, as if it were happening to them. Those changes stuck around for 5 days after they finished the book. Now flip to scrolling. A massive review published in Psychological Bulletin last September pulled together 71 studies covering 98,299 people. Heavy short-form video use (TikTok, Reels, Shorts) showed a clear pattern: worse attention, weaker self-control, and more anxiety. Consistent across teenagers and adults, across every platform tested. Oxford didn't name "brain rot" its 2024 Word of the Year for nothing. A 2024 brain wave study found that people hooked on short-form video had weaker activity in the front of the brain, the part that controls focus and impulse control. Separate brain scans showed the same thing: heavy scrollers had less activation in the exact regions that deep reading strengthens. UCLA neuroscientist Maryanne Wolf has been studying this for decades. Humans were never born to read. There's no gene for it. Reading is something we invented, and it hijacked neurons that were originally meant for recognizing faces. Over time, it built entirely new brain circuits connecting language, vision, and emotion. But those circuits only survive if you use them. Stop reading, and they fade. Wolf's conclusion is simple: screens built for speed produce a speed-wired brain. Books built for depth produce a depth-wired brain. One honest caveat: most of these studies are snapshots, not long-term tracking. People who already struggle to focus might just prefer short videos. But the same pattern showing up across nearly 100,000 people is hard to shrug off. The tweet repeats the line seven times. The research backs it up with brain scans, EEG data, and white-matter imaging across tens of thousands of people.

Students in England will be able to take a new qualification known as V-levels from 2027, under major reforms designed to give teenagers more flexibility in how they study after GCSEs. Education, finance and digital are the inaugural subjects to be offered from 2027 for students who want a more vocational pathway to work, alongside the bigger T-levels and academic A-levels.

I took a MASSIVE L in my career this week. MASSIVE L.

This was an eye opener from Jensen Huang When asked whether he would rather relive his 20s or be 20 years old today, this is what he had to say: "I thought our 20s were happier than these 20s. I think everyone deserves some time to be oblivious, and not wear all of the world's problems on their shoulders on Day 1 We are raising a generation that is very cynical and too informed They are cynical, not because they are inherently cynical. They are cynical because they see so much stuff. It is too much stuff You have to build up some internal reserve of optimism. You have to build up some reserve of goodness."

I’m working towards being the best silicone specialist I can be in prosthetics for amputee’s. I’m manifesting this. It’s literally going to be my life’s work. Doing all the extensive research I need right now to achieve this. I might need y’all help soon…

Dr. Gladys West, the Black mathematician whose brilliance made GPS possible, has passed at 95. Born on a Dinwiddie County farm during the Great Depression, she overcame segregation to become a scientist and map the world—literally. May we never forget her legacy or the path she paved for generations of mathematicians.

Insightful conversation with the founder of Pret a Manger.

@stylebender @stylebender I would love to be part of your camp for this one bro! 😄

Aaaah shit…here we go again! 😏

@AAApampa 👀💀

I guess this is not my year of matching pajamas. We’ll try again next year 🫠

Never be afraid to trust an unknown future to a known God.

You'll never look at your phone again after watching this ‼️‼️
