A Norwegian neuroscientist spent 20 years proving that the act of writing by hand changes the human brain in ways typing physically cannot, and almost nobody outside her field has read the paper. Her name is Audrey van der Meer. She runs a brain research lab in Trondheim, and the paper that closed the argument was published in 2024 in a journal called Frontiers in Psychology. The finding is brutal enough that it should have changed every classroom on Earth. The experiment was simple. She recruited 36 university students and put each one in a cap with 256 sensors pressed against their scalp to record brain activity. Words flashed on a screen one at a time. Sometimes the students wrote the word by hand on a touchscreen using a digital pen, and sometimes they typed the same word on a keyboard. Every neural response was recorded for the full five seconds the word stayed on screen. Then her team looked at the part of the data most researchers had ignored for years, which is how different parts of the brain were communicating with each other during the task. When the students wrote by hand, the brain lit up everywhere at once. The regions responsible for memory, sensory integration, and the encoding of new information were all firing together in a coordinated pattern that spread across the entire cortex. The whole network was awake and connected. When the same students typed the same word, that pattern collapsed almost completely. Most of the brain went quiet, and the connections between regions that had been alive seconds earlier were nowhere to be found on the EEG. Same word, same brain, same person, and two completely different neurological events. The reason turned out to be something nobody had really paid attention to before her work. Writing by hand is not one motion but a sequence of thousands of tiny micro-movements coordinated with your eyes in real time, where each letter is a different shape that requires the brain to solve a slightly different spatial problem. Your fingers, wrist, vision, and the parts of your brain that track position in space are all working together to produce one letter, then the next, then the next. Typing throws all of that away. Every key on a keyboard requires the exact same finger motion regardless of which letter you are pressing, which means the brain has almost nothing to integrate and almost no problem to solve. Van der Meer said it plainly in her interviews. Pressing the same key with the same finger over and over does not stimulate the brain in any meaningful way, and she pointed out something that should scare every parent who handed their kid an iPad. Children who learn to read and write on tablets often cannot tell letters like b and d apart, because they have never physically felt with their bodies what it takes to actually produce those letters on a page. A decade before her, two researchers at Princeton ran the same fight using a completely different method and ended up at the same answer. Pam Mueller and Daniel Oppenheimer tested 327 students across three experiments, where half took notes on laptops with the internet disabled and half took notes by hand, before testing everyone on what they actually understood from the lectures they had watched. The handwriting group won by a wide margin on every question that required real understanding rather than surface recall. The reason was hiding in the transcripts of what the two groups had actually written down. The laptop students typed almost word for word, capturing more total content but processing almost none of it as they went, while the handwriting students physically could not write fast enough to transcribe a lecture in real time, which forced them to listen carefully, decide what actually mattered, and put it in their own words on the page. That single act of choosing what to keep was the learning itself, and the keyboard had quietly skipped the choosing and skipped the learning along with it. Two studies. Two countries. Same answer. Handwriting makes the brain work. Typing lets it coast. Every note you have ever typed instead of written went into your brain through a thinner pipe. Every meeting, every book highlight, every idea you captured on your phone instead of on paper was processed at half depth. You did not forget those things because your memory is bad. You forgot them because typing never woke the part of the brain that would have made them stick. The fix is the thing your grandmother already knew. Pick up a pen. Write the thing down. The slower road is the faster one.

@RossionQ @marcorandazza Que chorradas dices el oxígeno es tóxico a partir de 200 pies, sino llevas una mezcla de gases (normalmente trimix) estarás muerto en muy poco tiempo

@marcorandazza I’ve been to 165 on air. Not for long and not in a cave, but while dangerous it’s not a death sentence. Had a dive master and a tech diver with me who are far more experienced, tech guy has done many 400+ foot dives

This was either group suicide or murder. I've been diving for 30 years. Rescue and deep dive certified. These divers were effectively dead the moment they went in the water. At 150 feet, with recreational gear and without special gas mix, you're already dead. I'm an absolute madman adrenaline junkie. My hard floor is 120 feet. There was no possible way they were coming back, whether they panicked or not. That dive plan was never going to end with any of them alive.

A company in Mexico rescued an orange stray cat and decided to hire him. They named him Engineer Miauricio and gave him the title of Emotional Support Director. His responsibilities are smiling at coworkers, gently meowing and walking around the office.

Lo que tiene evidencia sólida: el pico de NO nasal x15 y la mejora aguda de HRV. Lo que es mecanismo plausible sin prueba directa en humanos: los efectos cognitivos del NO (Francis et al., PLOS ONE, 2024) y la señalización circadiana.

Tararear (humming) 5 minutos eleva el óxido nítrico nasal x15 respecto a respirar en silencio. Ese gas hace cosas concretas en tu sistema nervioso antes de dormir. Lo que sigue está basado en estudios revisados por pares, con sus limitaciones incluidas 🧵

@heniuro @exfatloss You are running on stress ... Eat some carbs and relax you will see that temperature going down quickly

Recently I saw some Ray Peat disciples posting about how body temperature is a good proxy for thyroid health. Having been informed previously that keto ruins thyroid, I bought a thermometer to confirm. Is my thyroid cooked already or does it need few more years of no carbs?

@NutriRebel Mucho Ánimo Hernán!

Al final lo del cuello era cáncer de cavum generado por el virus Epstein Barr y no tuberculosis como creía la médico de cabecera 🤷🏻‍♂️. Ayer empecé el tratamiento con quimioterapia y radioterapia. Es un tipo de cáncer q no se puede operar pero q con quimio y radio puede desaparecer.

I hear this every week in my office: "Doc, my heart rate hits 150 during squats — that's cardio, right?" No. And if your cardiologist hasn't explained why, keep reading. 🧵

Han publicado el Manual Práctico del IRPF de la Agencia Tributaria. 700 páginas. No es que la información no exista. Es que está escrita en un lenguaje que aleja. Que no invita a leer. Que asume que eres jurista o que tienes a alguien que lo sea. 🧵

@gemagoldie @deaquidemadriz2 @Recuenco Jajaja fijate si es subnormal

@Jappy_octopus @deaquidemadriz2 @Recuenco Mira que digo mucho lo de no contestar a los que te hablan en plural xD

Le hemos amargado la vida a una generación.

@gemagoldie @deaquidemadriz2 @Recuenco 🤣🤣🤣🤣 cuando te meten en un saco es la hora de huir y bloquear hahaha

@deaquidemadriz2 @Recuenco No aprendéis quién? a qué colectivo se supone que pertenezco? Y la historia es la que es, la primera celebración oficial es la de 1910 en el marco del congreso internacional socialista archive.org/details/Intern…

Curiosidades...
