Today’s episode is definitely worth the paper it’s printed – and re-printed – on.
We use lots and lots of paper, hundreds of millions of tons a year.
Some of that paper gets recycled, and a lot of people have taken to flipping printouts over and using the second side rather than dispatching half-used papers.
But there are still some environmental costs with each page that gets written on or printed out.
But there may be a way to stretch those pages a lot further.
Researchers at Rutgers University has been developing a system that can UN-print the printing on standard printer paper.
A xenon lamp puts out pulses of light; then the system gives the paper a wipe with a bit of alcohol, and that separates the toner from the paper in a way that uses less energy and material than the conventional paper recycling process.
Each page can be used, wiped and re-used five times.
Now we just need a keyboard shortcut for un-printing like the one we have now for printing.
A new invention aims to make a trip to the hospital a little more fun, or at least a little less scary, for kids, and the inventor is a kid herself!
Ella Casano said she’s been getting IV infusions and has noticed that all the tubing and other equipment can be a little intimidating.
She came up with the idea of covering the IV bag with something cute – and maybe other young patients will feel better about those infusions.
She came up with a smiling plush bear that essentially hides the IV bag in a mesh pouch on its back.
Its name? The Medi-Teddy.
