Odd discovery on tic-toc currently resulting in research on Twitter.

On Hank Green's (PBS Sci-Show host, other You-Tube/Vlog education channels)Twitter feed he and some other scientists are discussing a tic-toc clip where a spider can apparently see into the infrared spectrum beyond where people can normally see.
At the time I'm posting this, they're also talking about how some people can also see further into the infrared ( as in, they can see the infrared signal from more modern remotes that don't have the extra red LED lights as a battery check) and his Twitter channel is discussing how this can happen and how to set up research.

Social media the way it is supposed to work.

1. I used to be in the trade.

Back then we'd point a remote control at a current video camera and watch on the display when a button is pressed. You would then see a purple pulse come from the remote LED.

As an aside, is your remote control is not working, take the batteries out, and hold down any button on it for a couple minutes, more times than not the remote would then work.

2. It's so cool that some animals can see colors that we can't

The most interesting animal, I think, is the mantis shrimp. They can see 10 times the number of colors as humans, far into both the infrared and ultraviolet spectrums. And some have a claw that can crack a crab’s shell wide open. They can’t be stored in a normal aquarium because they’ll bust the glass.
