Regenerating Worms and Addiction Research

Scientists can make a worm grow the head of a completely different species just by giving it

a drug. Meet the planarian flatworm, an animal with insane regeneration powers.

They can regrow their entire body, including their brain, from just a tiny

fragment. Researchers are using this to study the effects of drugs like cocaine.

When exposed, these worms show withdrawal-like behaviors similar to humans.

Incredibly, they can even retain memories after being decapitated and regrowing a new

brain. These seemingly immortal worms are helping us understand our own brains and

could be the key to developing new treatments for addiction.
