How To Hack Your Street Lamps Like An Astronaut

A bright street lamp can ruin a night of stargazing, saturating your retinas with light and washing out the comparatively faint glow of constellations and meteors.

This Microscopic Footage Shows What Happens When A Jellyfish Stings You

Cnidarians like anemones and jellyfish extend nematocysts, stinging organelles capable of shooting venom into another creature.

Is there poop on the Moon?

Here to give us the down and dirty on space excreta (because let's face it, you were always curious) is Minute Physics' Henry Reich and Smarter Every Day's Destin. It's a match made in YouTube science-explainer heaven. With poop. And spacecraft-trajectory-altering pee. In spaaaace. » 12/14/12 7:00am 12/14/12 7:00am
