Inside the Dreamy World of the Longest Jellyfish on Earth

I sincerely wondered if the otherworldly and beautiful creature in the photo above was real or computer-generated, perhaps for a sci-fi TV show. It is, however, very much of this world. This is the lion’s mane jellyfish, the longest jellyfish in the world. I’ll admit that I didn’t know much about jellyfish when I set…

The day we’ve all been waiting for is finally here. It’s the day I marked on my calendar months ago, the one that prompted me to buy my favorite snacks and a six-pack and to text my boneless friends that I love them. Maybe you commemorated the day early and will spend today in nervous…

This Noodle-Fingered Robot Is a Friend to Jellyfish

Forget flies—this robot is so gentle, it wouldn’t hurt a jellyfish. Which is saying a lot, since the gelatinous lifeform is especially prone to damage, according to David Gruber, a marine biologist at City University of New York. “Some of them fall apart just when they’re in your hand,” he said. “They’re this fragile ball…

Upside-Down Jellyfish Release Weaponized Goo Packed With Toxic ‘Grenades’

Swimmers in warm coastal regions often exhibit sting-like symptoms despite not coming into direct contact with venomous animals such as jellyfish. Scientists have now pinpointed the cause of these “stinging waters” to a particular jellyfish equipped with its own weaponized mucus. New research published today in Communications Biology describes the “cassiosome,” a stinging cellular structure…

Scientists Turned a Normal Jellyfish Into a Speedy Cyborg Jellyfish

Jellyfish are the most efficient swimmers in the ocean, albeit fairly slow ones. Researchers at Stanford University made a jellyfish swim three times faster by sticking a motor to it, creating a biohybrid robot with the jellyfish as the “scaffold.” The swimming cyborg was 10 to 1,000 times more energy efficient than other swimming robots,…
