Can a supervillain destroy the sun?
Although our sun is a dwarf yellow star, it’s more than massive enough to weather any attempts to alter it — super or otherwise.

This electric ‘slime’ might help injuries heal faster
Our bodies call in healing cells with an electrical signal. When stretched or squeezed, this gel makes electricity that could boost that alert.

Much of the sun’s light is green. Why does it look yellow?
Sunlight's peak intensity is at a green wavelength. Here’s why it doesn’t appear that way to us.
