ICYMI: 3D-printed ears, autonomous DARPA drones and more

An ear printed with a plastic material is able to grow capillaries when placed inside a mouse.

Today on In Case You Missed It: Wake Forest Institute for Regenerative Medicine scientists have 3D-printed living tissue that can be transplanted into living animals, most notably an ear that grew new cartilage and blood vessels once under the skin of a mouse for a few months.

While you're digesting that, definitely check out the work at Johns Hopkins School of Medicine, from prosthetic finger mind control to its work growing tiny brains in the lab.

Less frightening, more techy, DARPA just released a video of its Fast Lightweight Autonomy Program for drones, where a drone hit 45 miles per hour inside a closed test environment. The researchers are also testing drones navigation skills autonomously but that's a bit too slow for prime time just yet.

And a new Kickstarter project has a couple layers of fun for by-hand note takers. First of all, you can take photos of your notes in the matching RocketBook Wave app, and the notes will be automatically saved in the cloud storage space of your choosing. Next up though, the ink (if used with the proper style of pen) can be heated into disappearing so you can reuse the notebook on average, 10 times before the paper has taken too much of a flogging to be worth saving.

We also think the replica gun from a Japanese anime film is pretty cool to look at -- the fan version that comes out next month will cost about $170 but not actually do much besides look cool.

As always, please share any interesting science or tech videos, anytime! Just tweet us with the #ICYMI hashtag to @mskerryd.
