Northwestern University and Washington University School of Medicine researchers have developed the first example of a bioelectronic medicine: an implantable, biodegradable wireless device that speeds nerve regeneration and improves healing of a damaged nerve. Their device delivered pulses of electricity to damaged nerves in rats after a surgical repair process, accelerating the regrowth of nerves and enhancing the recovery of muscle strength and control. The device is the size of a dime and the thickness of a sheet of paper and dissolves in the body after about two weeks.
Animal behavior and movement can be followed and tracked with human-level accuracy by a new deep learning algorithm. This technique doesn't require tracking markers or arduous manual analysis. In this video, we see the algorithm track a mouse as it sniffs out an odor.
