Though just a prototype, this device enables a clinician to extract small amounts of cells from a mass inside of a patient, analyze the sample on the spot, acquire the results in an hour, and pass the results to other clinicians and into medical records rapidly. How much does the device cost to make? $200. Seriously, smartphones just got their own Samuel L. Jackson-esque wallet."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
