AnimalsTo clear loops, Sonic the Hedgehog must hit the right speed
Most animals don’t run through loops. Sonic would need the physics behind roller coasters and race cars to clear one.

EarthIt’s electric! Long-sought new field found in Earth’s atmosphere
This ambipolar electric field is weak. Yet it’s still strong enough to control the evolution of Earth’s upper atmosphere — and maybe life as we know it.

MathMath reveals how skateboarders can ramp up their half-pipe power
To pick up speed, half-pipe skaters pump — move between crouching and standing — as they roll. A new study shows the fastest way to the top.
