Want to heal your bones faster? Well, thanks to researchers at Northwestern University, pretty soon you'll be able to 3D print a flexible "scaffolding" to encourage bone growth on and around them.




Okay, taking a breath.

Here we go:

The scaffold is "made up of hydroxyapatite, a naturally occurring mineral that exists in our bones and teeth, and a biocompatible polymer called polycaprolactone, and a solvent. Hydroxyapatite provides strength and offers chemical cues to stem cells to create bone. The polycaprolactone polymer adds flexibility, and the solvent sticks the 3D-printed layers together as it evaporates during printing. The mixture is blended into an ink that is dispensed by the printer, layer by layer, into exact shapes matching the bone that needs to be replaced."




The idea, they continue, is that "a patient would come in with a nasty broken bone—say, a shattered jaw—and instead of going through painful autograft surgeries or waiting for a custom scaffold to be manufactured, he or she could be x-rayed and a 3D-printed hyperelastic bone scaffold could be printed that same day."

Currently the technology is being used to fuse spinal vertebrae in rats, and is performing well. Since you can't use this tech YET, maybe you can 3D print yourself a cast in the meantime:

Ever want to chuck your GoPro to get good aerial shots but don't have the right foam padding not to break it? Enter AER.





Their new invention--basically a giant Nerf arrow around a GoPro--makes it possible.



The videos sound like they wouldn't be worth seeing, but are surprisingly action-packed little bits of fun. I especially like the parts where it looks like you'll run smack into someone at the end of each one:

Microsoft tries too hard--yet again--in their new Surface Pro 4 ad geared ENTIRELY toward Hipster Millennials. The singing narrator wears a fedora and points out all the ways a Hipster Surface user can be productive. Mostly yawn-inducing, the one highlight is the inexplicably NIGHTMARE-INDUCING "hat for your cat" visual near the beginning:



We don't know what the hell you were thinking, Microsoft, but we want to see MORE of nightmare cat.

The Serval, also called the "Giraffe Cat" because... kitty:



...is quickly losing its habitat, becoming part of the illegal pet trade, and decreasing in numbers in the wild. Let's keep these beauties thriving, so see what you can do to help by going here.



All kitties are good kitties.
