Did I finally reach the limits of reason? And find the Devil waiting? And was that fear in his eye?

Dentures could become extinct.

Japan just hit a milestone that sounds ripped straight out of a sci-fi novel.

At Kyoto University Hospital, scientists have started dosing humans with a drug that could trigger the body to grow brand new teeth from scratch.

No drilling. No implants. No fake plastic plates floating in a glass beside your bed.

The trial kicked off in October 2024 with 30 men, ages 30 to 64, each missing at least one tooth. Phase one is purely about safety and dosage.

Here's the wild part.

Humans actually have a hidden, dormant third set of tooth buds buried inside the jaw. We just never grow them. A protein called USAG-1 keeps them switched off for life.

The drug shuts that protein down. Turn off the off-switch, and the buds wake up.

It already worked in mice and ferrets, which grew fresh teeth in lab studies led by Dr. Katsu Takahashi at the Medical Research Institute Kitano Hospital in Osaka.

If the human trials hold up, phase two will move on to children born with congenital anodontia, a condition where kids never grow a full set of teeth.

The team is aiming for public release around 2030.

That's not decades away. That's the next election cycle.

In Japan, where over 90% of people aged 75 and up are missing at least one tooth, this isn't just dental progress. It's a rewrite of what aging looks like.

The dentist of the future might not pull. They might plant a seed.

Jurassic Park almost got it right.

A mosquito frozen in time for 46 million years has been found with blood still locked inside its tiny body.

Not amber. Shale.

The fossil was pulled from oil shale beds in northwestern Montana, near Glacier National Park. Inside its swollen abdomen, scientists detected heme and porphyrin molecules. The exact chemical fingerprints of blood.

This is the first fossilized mosquito ever discovered with a blood meal preserved inside it.

The odds? Researcher Dale Greenwalt of the Smithsonian called it a one-in-a-billion shot. The insect had to suck blood, fall into a lake at the perfect moment, sink without bursting, and stay sealed in sediment for tens of millions of years.

It pulled it off.

Before sinking, this female mosquito likely fed on a bird or a small mammal during the Eocene epoch, around 19 million years after the dinosaurs vanished.

Now here's where Hollywood gets crushed.

DNA breaks down fast. Half-life of about 521 years. Completely unreadable after roughly 1.5 million. So even with blood inside, no Tyrannosaurus is getting cloned. Ever.

But the chemistry survived.

Iron. Porphyrins. The molecular ghost of a meal eaten before humans, before primates, before most modern mammals even existed.

A bug took one bite, made one mistake, and accidentally became immortal.

Seguramente ya habías visto esta escena en inglés… y sí, ya era bastante brutal.

It's absolutely incredible that they managed to bring this space beast back like a motorless glider.

We hurled a machine into the infinite, freezing void, then forced it to surf a 3,000-degree wave of plasma back to Earth.

Q3 millones: el precio por no prevenir una fuga de la que existían alertas desde enero.

¿Cómo los hubieras invertido ?
