Imagine that you’re a hungry predator foraging through the forest, hot on the trail of a juicy insect for your next meal. Deep in the forest, you pull back a leaf, and this creature starts wagging violently at you, sending you running for the hills:
The joke’s on you, because this frightening creature is most definitely NOT a snake. It’s actually a pupa (not a caterpillar, not yet a butterfly), ensconced in its chrysalis as it undergoes its remarkable transformation.
Dynastor darius is obviously a master of disguise, but it has more tricks up its sleeve besides its scary exterior … the pupa is still aware of the world outside of its chrysalis, and can shake from side to side (like a moving snake) to fend off the predator that wasn’t sufficiently spooked by its exterior.

Bacteria can be found virtually everywhere. They are in the air, the soil, and water, and in and on plants and animals, including us. In fact they cover your skin and you have literally trillions and trillions of bacteria in your gut.

Michael Jordan’s legendary slam dunk from the free throw line has been calculated at 0.92 seconds of pure hang time. But how many seconds could Jordan have gotten were he doing the same jump on the Moon? Or Jupiter?

Batteries are a triumph of science—they allow smartphones and other technologies to exist without anchoring us to an infernal tangle of power cables. Yet even the best batteries will diminish daily, slowly losing capacity until they finally die. Why does this happen, and how do our batteries even store so much charge in the first place?
