The treatment helped frogs grow working limbs useful for swimming, standing and kicking. It’ll be a while before people can do that.
Eukaryotes are living things whose cells package their genetic material inside a pouch called a nucleus.

A partner to DNA, cells use this molecule to translate the instructions for making all of the many proteins that your body needs to function.
An elephant's trunk can suck air through it fast — at more than 335 miles per hour (150 meters per second)!
