" Welcome to PM/AM, Popular Mechanics&amp;#039; morning briefing on the top science and tech stories for today.   A Purple-striped Jelly at the Monterey Bay Aquarium in California. (Photo credit: Sanjay Acharya) Yesterday, we learned how IBM built a microchip that mimics a human brain. The tables are turned in the case of jellyfish: In a new study, researchers say that a group of barrel jellyfish think like a supercomputer. According to LiveScience.com, the barrel jellyfish uses a hunting strategy that is similar to how supercomputers use algorithm that search for optimal solutions to complex problems. Unlike sharks or penguins, who can catch any old fish to survive, the barrel jellyfish depends on a big supply of plankton. So it may abandon its water depth and then dip deeper or glide higher to see if it can locate any plankton. If the jellyfish can&amp;#039;t find food at the new layer of water, it will quickly revert back to its original depth. It&amp;#039;s a strategy called fast simulated annealing, which basically means that jellyfish bounce around to eventually get closer to their food sources. It&amp;#039;s all about finding a practical solution to a difficult problem in a short amount of time, even though there&amp;#039;s a whole lot of other stuff (or noise) happening. Researchers have never observed this kind of behavior in another animal. So hooray for the barrel jellyfish! It makes me wonder if I can use fast simulated annealing as a strategy to search for lunchtime taco trucks.
