  • Patient receives 3-D printed skull after traumatic brain injury
    on July 20, 2017 at 5:19 pm

    After two months in a coma, Chris Cahill woke up confused about where he was and what had happened to him. Cahill was found unconscious from unknown trauma resulting in severe injuries to his frontal lobe, with brain swelling so dramatic it was life threatening. Physicians performed emergent surgery to relieve the brain swelling with the intent of replacing the skull after the swelling subsided. However, the patient's own skull was infected and as a result was unusable. At that point, the doctors decided the best solution to replace the missing skull bone was to use 3-D printing to create a custom cranial skull implant.&nbs […]

    Ask Siri to find a math tutor to help you 'grasp' calculus and she's likely to respond that your request is beyond her abilities. That's because metaphors like 'grasp' are difficult for Apple's voice-controlled personal assistant to, well, grasp. But new research suggests digital helpers could someday learn the algorithms that humans have used for centuries to create and understand metaphorical language. […]
