Regeneration of fins and limbs relies on a shared cellular playbook
The findings strengthen the case that regeneration is an old trait, offering insights into how complex tissues rebuild themselves.

Motor neurons don’t just move muscles. They may direct that motion too
A fruit fly study shows motor neurons do more than relay commands: They send signals back to the brain and organize movement sequences.

A new dino fossil may solve an ancient murder mystery
A newly-described dinosaur, Jian changmaensis, may have glided through northwestern China about 120 million years ago, wreaking havoc on birds.
