Science writer Ed Yong has fun with poop and bats and flesh-eating plants of the Pacific in this piece for NatGeo.
Imagine a bat flying through the jungle of Borneo. It calls out to find a place to spend the night. And a plant calls back. The plant in question is Nepenthes hemsleyana—a flesh-eating plant that’s terrible at eating flesh. It’s a pitcher plant and like all its kin, its leaves are shaped like upright vases. They’re meant to be traps. Insects should investigate them, tumble off the slippery rim, and drown in the pool of liquid within the pitcher. The pitcher then releases digestive enzymes to break down the corpses and absorb their nitrogen—a resource that’s in short supply in the swampy soils where these plants grow.
But N.hemsleyana has very big pitchers that are oddly short of fluid and that don’t release any obvious insect attractants. And when Ulmar Grafe from the University of Brunei Darussalam looked inside them, he saw seven times fewer insects than in other pitchers.
Instead, he found small bats.
TIL: Sharks are attracted to the sound of death metal. Apparently, the “dense tones” of it mimics the “low frequencies of struggling fish.” (Damn.) In 2015, a Discovery Channel crew — hoping to attract a large great white named “Joan of Shark” — dropped a speaker underwater and played some. Independent: Desperate to feature the […]
The mystery of the glorious fireball emitted by microwaved grapes (featured in my novel Little Brother) has been resolved, thanks to a paper in the Proceedings of the National Academy of Sciences in which Trent University researchers Hamza Khattak and Aaron Slepkov explain how they destroyed a dozen microwaves before figuring out that the grapes […]
The rise in a belief that the Earth is flat is bizarre and somewhat frightening, a repudiation of one of the most basic elements of scientific consensus. Texas Tech University psych researcher Asheley R. Landrum attended a 2017 flat earth convention and interviewed 30 attendees to trace the origins of their belief in a flat […]
Just a reminder: Print isn’t dead. And now that printers are becoming as portable as cell phones, it might be around for quite some time. Enter the MEMOBIRD Mobile Thermal Printer, a mini-printer that is versatile, portable – and most importantly, never needs a refill on ink or toner. Measuring just a few inches around, […]
What do Facebook, Twitter, YouTube and Google all have in common? Somewhere in their framework, they all use MySQL, that most versatile (and free!) of database management systems. And they’re not alone. If your company or the one you’d like to work for wrangles data (and who doesn’t?), they’re going to need someone with a […]
There’s a reason you’re hearing about the gig economy in every other business story these days. More than ever, people are finding income from more than one source. And if you find the right one, a side hustle can do more than just pad your pockets – it can allow you to finally get paid […]
