JUST 1 DOLLAR OR TWO

As many Hicksville Residents are already aware of, Hicksville's "Hidden Gem" is going it's first year without proper funding since the 1970's and is now at risk of closing forever. The Hicksville School district removed us completely from the annual budget and bringing an abrupt end to an otherwise beneficial long term relationship. Hicksville residents had year long unlimited free admission as part of the agreement with the Hicksville school district. That being any Hicksville resident could visit and receive our full tours without paying a cent in admission. Now with the loss of this funding not only does our museum have to start charging Hicksville residents admission for the first time in about half a century, but we have to ask Hicksville residents to help us raise money to remain open into next year. In order to cover the costs of our educational services to about this time next year, we need to raise roughly $90,000. This will give the museum enough time to negotiate new sources of funding as well as grants. Please. Help Save the Hicksville Gregory Museum.

We aren't asking much, if every Hicksville resident donated just a dollar or two, this would buy us the time we need. Please share this link with your neighbors and donate a dollar or two:

Interesting story.

Jo Nagai was eight years old when he noticed something strange. His hand-raised swallowtail butterflies seemed to recognise him. Wild ones didn't. He wanted to know why.

So he wrote to a Georgetown University entomologist. She wrote back.

What followed was one of the most remarkable scientific collaborations in recent memory - between a second-grader in Kobe, Japan and Dr. Martha Weiss, who had previously proven that moths can retain memories through the complete cellular breakdown of metamorphosis.

Jo proposed replicating her study on butterflies. Using equipment he designed himself, he trained caterpillars to associate a mild vibration with the scent of lavender. Then he waited for metamorphosis — the process that completely dismantles and rebuilds an insect's brain from scratch.

When the adult butterflies emerged, 70 percent still avoided the lavender scent. Their memories had survived a process that should have erased them entirely.

Then came the discovery nobody expected.

When Jo bred those butterflies, their offspring — who had never experienced the vibration — also avoided lavender. So did the generation after that. A learned memory had been passed down biologically, without any direct experience, across two generations.

Jo documented everything in a 33-page paper. He presented it at the International Congress of Entomology at age ten, alongside Dr. Weiss.

The implications reach far beyond butterflies. If learned experiences can be encoded and inherited, it changes how we think about genetics, memory, trauma, and what parents pass to their children without ever meaning to.
