http://www.sciencemag.org/news/2016/07/robotic-stingray-powered-light-activated-muscle-cells Okay this is one of the strangest news stories I think I've seen and I can't believe I missed it like 2 years back (where does the time go) but like cool artificial stingray bio-robot thing made from heart cells and a gold skeleton.

Damn is this some scifi science or what?
