Biologists turned snails into tweakers to learn more about how crystal meth seems to improve memory in humans. According to the Washington State University and University of Calgary researchers, memories formed while on methamphetamine may be more durable. (They ran another snail study in 2006 using cocaine instead of meth.) Their work could someday provide a deeper understanding of addiction. From EurekAlert! (images from Wikimedia Commons):
...The team wondered whether meth could improve the snails' memories. First they immersed the snails in meth-laced pond water, then they moved them into regular de-oxygented pond water and gave them a training session that the snails should only recall for a few hours. In theory the snails should have forgotten their training 24 hours later, but would the meth improve the snails' memories so they remembered to keep their pneomostomes closed a day later? It did. A dose of meth prior to training had improved the snails' memories, allowing them to recall a lesson that they should have already forgotten. And when the team tested whether they could mask the meth memory with another memory, they found that the meth memory was much stronger and harder to mask.

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 […]
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 […]
High-def cameras are available to anyone and for much less than they were just a decade ago. Even the phones in our pockets can be used to shoot and edit short films. It’s never been easier to be a filmmaker, providing you have the technique. Enter the Film & Cinematography Mastery Bundle, an online boot […]
