Of the many problems on Earth, here are two: there are too many jellyfish in the seas
This week’s roundup includes sex, violence, and truffles—the last of which is not unlike the drug trade, with a surprisingly shady underside. So, without further ado, here’s this week’s R-rated landscape reads.
It’s not uncommon to be on the receiving end of jellyfish’s sting when you go for a swim in the sea—but what is it that provides that numb feeling you get as a result? And should you really pee on it to make it better?
Say hi to the Portuguese man o’ war. It’s purple, it’s clear, it looks like a balloon, it’s painfully venomous, but it’s not a jellyfish and you wouldn’t have to convince me too hard that it’s from an alien world. This Portuguese man o’ war, which other than being a fantastic name, washed up on a beach to freak people out (and to expose the alien hideout that is the ocean).
It seems logical that if you’re designing a flying robot, you might borrow a few ideas from Mother Nature’s airborne repertoire. But researchers at NYU instead too their inspiration from under the sea for this unusual robotic craft that flies through the air the same way a jellyfish moves through the ocean.
Of all the unique varieties that Ben & Jerry’s has concocted over the years, nothing can come close to the wonderful absurdity that is this glowing ice cream created by Charlie Francis. Using a synthesized version of the luminescent proteins that cause jellyfish to glow when they’re agitated, this gleaming frozen treat actually gets brighter as you lick it.
Now this is called a major mistake – apparently, a robot whose sole purpose is to remove them nasty jellyfish from our waters could end up doing the exact opposite, that is, by ending up with more jellyfish than before. What you see above happens to be JEROS, also known as the Jellyfish Elimination Robotic Swarm, which is currently being tested before it is commercially released. A team of engineers over at South Korea has come up with JEROS, where it was designed to get rid of jellyfish swarms. Making use of a camera and GPS system in order to determine where the jellyfish swarms are underwater, it will then make a move in the right direction, where a huge net underneath it gathers the jellyfish before a special propeller is meant to make short work of them.
Unfortunately, according to Robert Condon, a research scientist with the Dauphin Island Sea Lab who studies jellyfish, he claims that the JEROS the jellyfish-destruction robot could eventually end up creating additional jellyfish. It might kill the jellyfish, but it does not do a good enough job to destroy the jellyfish’s eggs and sperm. Rather, it mixes it all up in one spot, which in turn increases the chance of them discovering each other. Talk about returning with a vengeance!

Jellyfish are amazing creatures, travelling in massive blooms and pulsating mesmerically to drive themselves through the water. But how does that simple motion manage to push them through the water so quickly?
Glowing bunny rabbits aren’t just for Sherlock Holmes reboots and acid trips anymore. Scientists from the University of Hawaii recently collaborated with a team from Istanbul, Turkey, where a couple of bright green lab rabbits were just born as part of a larger effort to better understand hereditary illness and make cheaper medicine.
