Skulls in the Stars: Mr. Faraday goes wild — with atomic speculation! (1844)
There’s discussion of hard impenetrable spheres, but no, it’s not a “spring break” exposé. Just good old physics.

Shock doc’s new electrifying party trick
The project, which Dr Peter Terren calls the Modern Thinker, involves passing about 200,000 volts of electricity over his body, a routine that transforms him into a human sparkler for all of 15 seconds.
Scientists give a hand(edness) to the search for alien life
“If the surface had just a collection of random chiral molecules, half would go left, half right,” Germer says. “But life’s self-assembly means they all would go one way. It’s hard to imagine a planet’s surface exhibiting handedness without the presence of self assembly, which is an essential component of life.”
Because chiral molecules reflect light in a way that indicates their handedness, the research team built a device to shine light on plant leaves and bacteria, and then detect the polarized reflections from the organisms’ chlorophyll from a short distance away. The device detected chirality from both sources.
