A team of researchers believe edible QR codes are the future of medicine. Using QR codes, the dosage can be tailored to the patient. When scanned, the code will show all information about the drug, preventing people from taking the wrong medication.
In the long view, modern history is the story of increasing rights of control over your body – for instance, in matters of reproduction, sex, where you live and whom you marry.

During the early part of the last century, dyes were frequently used to disinfect wounds. During the first world war, thousands of lives were saved by “flavine therapy” which used dyes such as Brilliant Green and Acriflavine.

But now these dyes are being resurrected to treat bacterial infections, but with a new twist: light.
Researchers at Lund University in Sweden have used a completely new preclinical technique and analysis of tissue from patients to show exactly what happens when certain patients with Parkinson's disease are restored as a result of nerve cell transplants. They have also identified what makes many of the transplant patients develop serious side effects in the form of involuntary movements.
