Arthur C. Clarke once wrote that “any sufficiently advanced technology is indistinguishable from magic.” Well, good news, scientist-wizards: the creator of a new blood-type test cites a bit of magic from Harry Potter and the Chamber of Secrets as his inspiration!
Engineer Wei Shen created a papery surface for blood testing that displays its results by “writing” the blood type letter of the sample that touches it. Shen says that this technology was inspired by Tom Riddle’s diary, which wrote magical messages to Harry Potter. Inspiration is super important for scientific advancement, so keep reading and you too can make some magic happen!
