Welcome to STEMology – Show Notes
Season 1, Episode 16
Sleepy sharks, Bird-brain song, FISSTING hiccups, and the diets of rodents
In today’s episode of STEMology…
We’ve finally discovered how sharks sleep, researchers have translated brain activity into artificial bird song, FISST has been invented to cure hiccups and the food lab rats are being fed could be disrupting our scientific discoveries
What they’ve basically discovered is that sharks hanging out in a certain place so that they can kind of surf the ocean currents in a conveyor belt figuration, which allows them to take turns resting.
Their ultimate goal is to come up with this communications prosthetic that allows people to speak if they’re not able to speak. And they’re studying this in zebra finches, because this is a species that produce song…. and it’s very complicated, which make them quite a good model for figuring out how to turn the activity of the sensory motor cortex, which is where the speech comes from into song.
There are some people who actually get hiccups through no fault of their own. you’ve got patients who have maybe brain and stroke injury. What I didn’t realize was that some kinds of chemotherapies cause hiccups, there’s all these people who actually suffer from hiccups.
Turns out that potentially by feeding our lab mice and rats the wrong kinds of food, we are possibly confounding variables in experiments …. we are kind of forcing a different outcome, maybe accidentally.
This is a “kind of, sort of, vaguely close” copy of the words that David & Sophie speak in this episode.
