UNT and Stanford researchers say they've overcome a major barrier to artificial organ size: until now, organoids without blood vessels couldn't grow larger than about 3 millimeters—roughly the size of the sesame seeds picture above—before dying from lack of oxygen and nutrients. Seeds shown are not to scale. [Image: Pinchai Puntong/istockphoto]
USAA has received a newly granted patent (USPTO #12346421) for a system that uses tattoo detection to verify a person’s identity in video. Invented by Carrollton-based William Daniel Farmer, the method involves a hidden tattoo—made with ink invisible to the human eye—used as a cloaked token. When detected in video footage, the system can authenticate the user and authorize secure access to services or information. [Image souce: USPTO Patent #12346421; DI Studio composite image]
