We have the technology - we can make a jellyfish out of rat parts!

Nature reports on some interesting work done by a team of researchers at Harvard and Mass. General, who found inspiration at the jellyfish exhibit at the New England Aquarium.

"We took a rat apart and rebuilt it as a jellyfish," one of the researchers said. But don't worry - they're not all sitting around in a secret underground lair going "mwa-ha-ha!" as they build giant tanks to house their earth-conquering ratfish. We think. They say the work, in which rat heart cells were grown on a thin plastic layer, could aid in battling heart disease and developing drugs, by giving researchers a better understanding of the "fundamental laws of muscular pumps."
