Rather than hydraulic actuators, springs or hinges, these tiny "bio-bots" are powered by living muscle tissue.
Researchers at the University of Leeds say their digital scanning system produces high-res images that can be rotated.
As Han Solo would undoubtedly tell you, Chewbacca's hardly a fair-weather friend. This week, our winner-take-all team of crafters takes on a Chewie tissue box cover.
UCSF researchers are able to hold a mouse's lung tissue still long enough to image individual cells, which could help them see how cells respond to injury and disease, according to their report.
One team of scientists implants functional lab-made lung tissue into rats, while another makes a microdevice that mimics real lungs and could be used to test drugs.
A new technique called micromasonry uses a gel-like material to bind cell bricks together as the material hardens, enabling the formation of 3D shapes to build such things as new organs.
Organovo start-up is working on bioprinting tech that could eventually make it possible to use specialized 3D printers to repair or replace blood vessels.
Using a standard remote-control chassis, you put a tissue box on top and drive the absorbent paper to its destination. Think of it as a bomb disposal robot that enters dangerous contaminated territory where no man should tread.
Be careful--this smiling helper could be spying on you too
Researchers have successfully replaced 20 per cent of a rat's oesophagus with an artificial organ grown in a lab.
