Jo Nagai was raising swallowtail butterflies at his home in Kobe, Japan, when he noticed something odd. The ones he had looked after as caterpillars seemed to recognize him. Wild butterflies fled. His didn't.
He was in second grade. He wrote a four-page letter to Dr. Martha Weiss, an entomologist at Georgetown University who had studied whether moths could retain memories through metamorphosis. He asked if she could help him design a version of her experiment for butterflies.
She said yes.
Using a muscle therapy device, Jo trained caterpillars to associate the scent of lavender with a mild vibration. When the caterpillars became butterflies, 70 per cent of them still avoided the lavender. Their brains had been completely rebuilt during metamorphosis. The memory survived anyway.
Then he bred them.
The offspring, which had never been trained, also avoided lavender. So did their grandchildren. Without ever experiencing the vibration, two generations of butterflies inherited an aversion to a scent their grandmother had been taught to fear.
Jo documented it all in a 33-page research paper and presented his findings at the International Congress of Entomology in Kobe in 2024. He was 10.
A second grader wrote a letter to a Georgetown professor, and together they found evidence that butterflies can pass memories down through generations.

"A teenager turns down Kansas, Kentucky, UCLA and Michigan to take graduate-level coursework as a college freshman at Berkeley, and the response from the people paying him millions isn’t excitement. It’s suspicion. That was never a scouting report. That was a diagnosis. And the disease was intelligence."

Breaking down the double standard with how Angel Reese’s emotions are received compared to Caitlin Clark & Hailey Van Lith. Comment below why you think they get different treatment.
Accelerator is just another word for an educational institution aka school
If YC, 500 Startups, Techstars, Thiel Fellowship, etc can teach first time founders how to start billion dollar+ companies in 3 months w/ network support, don't you think it can be done for any skill set?
