Lucy Hobbs applied to dental school in 1859. They rejected her. Women couldn't be dentists. She apprenticed under a dentist instead, built a thriving practice, and applied again. This time the Ohio College of Dental Surgery admitted her as a student — then gave her full credit for her years of practice. She graduated in 1866. First woman in history to earn a dental degree. She immediately started training other women.

Someone open-sourced a fully unfiltered AI chat interface No sign-up. No guardrails. Full codebase on GitHub. Meanwhile OpenAI won't let you ask about aspirin without a safety disclaimer 💀

Claude Code just got a desktop mode with hotkeys and it's literally on fire The AI coding assistant is now faster to navigate than your own IDE We're 6 months away from devs just narrating code into existence 🔥

Your neighbor saved his entire life for retirement. Never traveled. Never bought the things he wanted. Never enjoyed life. Died one week before retiring. Stop optimizing for a future that isn't guaranteed 💀

Conspiracy theory: no human team ships this many updates this fast. Claude is clearly fine-tuning itself at this point. Anthropic employees are just there to press deploy 🫠

Your AI agent can now have its own iMessage number 2 commands. That's it. We went from 'AI will replace us' to 'AI is texting our friends pretending to be us' real quick 😂

AI-generated cinema is getting absurd Someone typed 'hunter gets ambushed by furry creature in a forest' and got a movie-quality scene out of it We're maybe 6 months away from a full AI film winning at Sundance and nobody will admit they liked it 🎬

The Waterloo Teeth were dentures made from the teeth of dead soldiers. After the Battle of Waterloo in 1815, scavengers pulled teeth from 50,000 corpses on the battlefield. These were exported to England and used by dentists for the next decade. They were considered premium quality. Demand for battlefield teeth was so high that soldiers started pulling teeth from the living.

Queen Elizabeth I had such severe tooth decay that visitors described her breath as unbearable. By her 60s, she had lost so many teeth her cheeks had sunken in. She stuffed cloth in her mouth for public appearances to maintain her silhouette. Sugar had just arrived in Europe from the New World. The wealthy consumed it obsessively. Rotted black teeth became a status symbol — it meant you were rich enough to afford sugar.

The tooth worm was the official medical explanation for tooth decay for over 4,000 years. Ancient Mesopotamia, China, Egypt, medieval Europe — they all believed a tiny worm lived inside your tooth and bored holes in it. The treatment was fumigation: burning henbane seeds under the tooth and inhaling the smoke. Henbane is toxic and mildly hallucinogenic. The worm theory wasn't officially disproven until 1728.

agents are now learning how to write their own video gen prompts so basically AI is automating the one skill that AI video people thought made them special the prompt engineer → AI pipeline is completing the loop faster than anyone expected 🔄

karpathy's autoresearch ran 70 experiments on its own and pushed a vibecoded chess engine to ELO 2718 the AI literally taught itself to be a top 50 grandmaster while the developer was probably eating lunch we're not building tools anymore. we're building employees that don't need bathroom breaks 🧠

In ancient Rome, having white teeth was a sign of wealth. The whitening method: human urine. Portuguese urine was considered the most effective and was imported and sold specifically for this purpose. The ammonia in urine actually works as a bleaching agent. Dentists used versions of this until the 1800s.

Sailors in the 1700s were losing all their teeth before age 30. Not from fighting. From food. The Royal Navy diet was: salted beef, hardtack biscuits, and rum. No vitamin C. No fresh vegetables. Ever. The result was scurvy — gums that bled, then rotted, then your teeth just fell out. A Scottish doctor named James Lind proved citrus cured it in 1747. The Navy took 48 years to act on this information. 48 years of toothless sailors.

In 1844, a dentist named Horace Wells watched a man inhale laughing gas and fall hard on his leg. The man felt no pain. Wells realized nitrous oxide was the key to painless dentistry. He had his own tooth pulled the next day under gas. It worked perfectly. Three months later, he demonstrated it at Harvard. A student groaned. The crowd called him a fraud. He never recovered. He died by suicide in a jail cell at age 33. Nitrous oxide is still used in dental offices today.

William Halsted invented nerve block anesthesia. He tested it on himself first. That's how he discovered cocaine completely eliminates pain. He spent the next 30 years as a functioning cocaine and morphine addict — and became one of the greatest surgeons in American history.

Chroma just dropped a 20B parameter open-source search agent faster than the competition by 10x cheaper by 10x Apache 2.0 the agentic search space went from 'we need $50M in funding' to 'here's the weights, go crazy' real quick 🔥

someone made an app that uses your Mac's accelerometer to moan when you slap it made $5,000 in 3 days no ads, no subscriptions, just pure unhinged engineering we are living in the golden age of software and honestly I've never been more proud of humanity 😭

George Washington's dentures weren't wooden. They were made from: - Hippopotamus ivory - Cow teeth - Human teeth pulled from the mouths of enslaved people at Mount Vernon The wooden myth exists because the ivory stained dark over time.

The barber-surgeons pulled teeth in the street between haircuts. The bloody rags they hung outside to dry became their advertisement. Red stripe = blood. White stripe = bandage. That's where the barber pole comes from.
