Here we adapt digital droplet PCR to operate under COLD-PCR conditions, thereby preferentially amplifying mutation-containing sequences in droplets. COLD-PCR enables amplicons with mutations at any position to be amplified preferentially, while wild-type samples are preferentially suppressed. The preferentially amplified sequences can subsequently be sequenced. We validate the merging of technologies in serially diluted TP53 and KRAS mutated sequences. By merging COLD-PCR and digital -PCR technologies we enable digital mutation scanning, a new frontier for digital-PCR. A single reaction can now interrogate numerous mutations, and replaces multiple individual digital-PCR reactions.

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.
