A new surgical knife produced by Zoltan Takats of Imperial College London can help surgeons confirm they’ve removed cancerous tissue. Typically in a routine cancer extraction procedure, a surgeon vaporizes tumors as they cut, producing smoke.

This knife has the potential to be very valuable if it can definitively indicate whether doctors have removed all cancerous tissue.
