Earth is still in an Ice Age, and almost nobody knows it.
Ice ages don't end when the glaciers melt; they end when all polar ice disappears completely. Right now, ice still covers Antarctica and the Arctic; which means by scientific definition we are still in an Ice Age.
What we are living in - right now - is called an interglacial period, a warm pause, a temporary thaw between glacial advances. The current interglacial - called the Holocene - began about 11,700 years ago. Every human civilisation, that has ever existed - Ancient Egypt, Rome, China - all of it happened inside this single warm pause.
And here is what makes this deeply unsettling; in the last 2.58 million years the Earth has cycled through at least 50 glacial advances. The warm pauses between them typically last 10,000 to 30,000 years. We are already 11,700 years into ours.
The ice cores drilled from Antarctica tells us exactly what happened before. Every interglacial ends; every one! The temperature drops, the glaciers advance, and ice sheets kilometres thick crush everything beneath them.
During the last Glacial Maximum just 20,000 years ago, ice sheets covered most of North America, Northern Europe and Asia. New York City was under a kilometre of ice. And none of that required a catastrophe.
It happened slowly and quietly, driven by wobbles in Earth's orbit around the Sun, called the Milankovitch cycles. The next glacial advance will come; not tomorrow, not in our lifetime. But it will come.
We are not living 'after' the Ice Age: We're living inside it.

Oh, Wow! 😲 Could we send information to the past or to the future?
🚨 Japan’s Quantum Breakthrough Could Change Everything!
Imagine sending information instantly across space without wires, without satellites… just pure quantum magic. Scientists in Japan have made a shocking discovery with a mysterious “W state” — a special kind of quantum entanglement that could open the door to the future of quantum teleportation. While this doesn’t mean people or objects are teleporting yet, it’s a huge leap toward a world where quantum communication is faster, safer, and almost sci-fi level. Experts say this breakthrough could transform computing, secure messaging, and the way we share information across the universe. Could this be the moment when science fiction starts to become reality?

Disney has partnered with Adobe to develop AI tools that turn artists' sketches into finished concept art.
The deal is the latest example of Disney's investment priorities in a year otherwise defined by layoffs and cost-cutting.

Dani Roman and Fred Fugen have set two Guinness World Records after launching from a giant catapult inside the tallest chimney in Europe.
A human catapult was built inside a nearly 1,200-foot-tall chimney in Trbovlje, Slovenia.
The 200-foot system accelerated the men from 0 to 110 miles per hour in just 2.15 seconds before they were thrusted out of the chimney into the air.
They then parachuted to the ground.
The highest point in flight for the daredevils was 1500 feet off the ground.
Insane.

Damn, talking with the AI from @nuance_ai is pretty amazing.
First time I've interviewed an AI like this.

In 2015, I built an AI that detects early cancer.
It’s still running across hundreds of hospitals in the US today.
It was the most fulfilling work of my life, and I was building in AI years before everyone called it “AI”.
Building in AI then was a dream.
Now It feels like we’ve taken a turn for the worse.
It started when i was in undergrad.
I built my first company: AI models that made the political data transparent to voters.
At 21, I was offered six figures for it, but the buyers wanted to use it for reasons I couldn't ethically support.
So we turned down the offer and shut down the company instead.
In 2014, I moved into deep learning research on language models, for the Intelligence Community and Goldman Sachs.
Then HCA Healthcare came to us.
They put me in a competition against 10 people from IBM Watson. It was just me and the tools I’d built.
Our job was to build an AI model that can catch the cancer that slips through the cracks in hospitals.
It was the most intense 30 days of my life. Multiple all nighters.
My models won. That turned into a $5M deal, and later its own company, Azra AI.
Then the world caught on.
ChatGPT and Claude arrived, and AI costs exploded.
Building in AI in 2015 felt novel.
We were using it to find cancer tumours and save lives.
Now the biggest tech companies have turned AI into a money extraction machine.
That’s when I decided to make a change.
We raised $8.5M to build a better future for AI.
On Wednesday, we’re launching Rayline.
AI shouldn’t be locked inside a few labs’ models, prices and clouds. It should be open, transparent and decentralized.
More on Wednesday.

Bernoulli-Euler Double Generation Theorem. This Demonstration generates a circle roulette in two equivalent ways, in accordance with the "double generation" theorem of Euler and Bernoulli. We get a hypotrochoid or epitrochoid, depending on whether the rolling circle is inside or outside the fixed circle

My fellow anesthesiologist Dr. William Perez was so disturbed by the operating room experience of anesthetizing brain-dead donors that he refused to continue participating:
“First, I had to provide anesthesia to the brain-dead organ donor in a virtually identical fashion to that which I provide for other critically ill patients. It turns out that brain-dead patients react to scalpels and electrocautery similarly to my other patients. Without adequate anesthesia, they become tachycardic and hypertensive. Perhaps even more bothersome was the fact that I had to administer paralytics to prevent our organ donors from moving during the case.”
“The first thing I noticed was the normal respect for the patient seemed to be missing from the room.
Part of this may be that harvest teams are almost invariably from outside institutions and organ procurement companies. They travel about harvesting organs routinely and seemed, at least to me, unconcerned with the organ donor as a person.
Perhaps everyone simply considered the patient on the table to be gone, so they acted consistently with that. But the joking, the music, the conversation—it all seemed so out of place.”
“From cutting out and removing the heart, lungs, and liver to the later harvest of corneas and replacing long bones with the equivalent of broomsticks, the entire sequence was somewhere between disturbing and horrific.”

The Weimar hyperinflation of 1923 wasn't just an economic crisis; it was the systematic destruction of Germany's middle class and the social order that held society together. When the government chose to finance its deficits by printing money rather than raising taxes or cutting spending, it unleashed a monetary catastrophe that would reshape German society forever.
By November 1923, it took 4.2 trillion marks to buy a single US dollar. Teachers, engineers, and civil servants who had saved their entire lives watched their nest eggs become worthless overnight. A lifetime of prudent saving couldn't buy a loaf of bread, while speculators and debtors who had borrowed heavily found their debts evaporated by inflation.
The psychological trauma went far deeper than the economic devastation. The German middle class had built their identity around thrift, hard work, and delayed gratification. Values that hyperinflation made not just useless but actively harmful. Those who had played by the rules were punished, while those who abandoned fiscal responsibility were rewarded.
This wasn't merely monetary policy gone wrong, it was the foundation for the political extremism that would follow. When money loses meaning, society loses its anchor, and people become desperate enough to embrace radical solutions. The lesson remains: sound money isn't just about economics, it's about preserving the social fabric itself.
Amazing! 😲😲😲😲😲
Super excited to share what we've been building at our @UniOfYork spin-out @pxld_ai, now out of stealth.
DAWN is our foundation model for world harmonisation. Give it a video of yourself and any world (a photo, a video, a 360 or a 3D scene), and it puts you into that world. The light, shadows and reflections are rebuilt to match, and you have real effects on the scene around you, so it looks like you were really there.
It's insanely strong at maintaining performance fidelity. Your performance and your identity come through exactly as you shot them, down to individual strands of hair and the subtlest microexpressions. Nothing about you is regenerated: every frame is kept, and only the world and its light change around you.
Also, every video we've shown is one-shotted. No re-running with different seeds.
It's been amazing to bring together the work from my PhD into tools that are this useful and this powerful.
Have a look:
🔹 Hair-level detail and identity kept exactly as shot, with the light rebuilt around you pxld.ai/#take
🔹 One take into any photo, video, 360 or 3D scene pxld.ai/#location
🔹 Full control of the light. Place lights anywhere in the world including behind the camera, just like you would on a real set pxld.ai/#cinematographers
Early access is opening up at pxld.ai. Or send me a take of yourself and tell me where you want to be.
Huge thanks to my cofounders @WillRowan3 and @WillSmithVision. It has been so much fun working on this together.
