He [Samuel Guthrie] - for reasons best known to himself - mixed together two gallons of whiskey with a couple of pounds of chlorinated lime. He put them together and then fed this substance to his daughter. She took a sip, declared it quite delicious then passed out. He decided to market it as a stimulant; he never realized that, in fact, it was an anesthetic.

So who here speaks Dutch? Because I REALLY want to know why there are dissected thoracosacrophagus twins, a deformed spinal cord (which I think is from the twins), a fetal kitten, and what looks like a meat grinder, all together…

Amoeba Sized Insect Is Missing Some Pieces
by Karl Gruber
You can’t shrink down to the size of an amoeba without losing parts of yourself. That’s the lesson one researcher is taking away from a microscopic analysis of the fairy wasp (Megaphragma mymaripenne), which at a mere 200 micrometers in length is one of the world’s smallest animals (shown compared to a paramecium and amoeba above).
When the scientist compared the neurons of adult and pupae fairy wasps, he discovered that more than 95% of adult neurons lack a nucleus. The findings, reported online this month in Arthropod Structure & Development, suggest that while a complete set of neurons is needed to grow, far less are required to live. And that helps the wasp shrink so small that it can avoid most predators and invade the eggs of other insects.

The scale of miniaturization of microchips (integrated circuits) is well illustrated here, and technological achievements continue to make them smaller. Microchips are used in computers and many other electronic devices, carrying complex microscopic circuits printed into thin wafers of silicon.

This portrait of Nikola Tesla was done by my friend Max Lowe at Cherry Bomb Tattoo in Martinsburg. His apprenticeship just ended recently so I let him do his first human portrait on my shoulder. It’s not finished yet, electricity and finishing the tower are soon to come.
