Future stitches could be made out of your own muscle cells, ensuring proper re-growth of injured muscle tissues.
Researchers in Massachusetts are implanting injured mice with microthreads coated with human muscle cells, reports Technology Review. The threads are made of the same proteins the human body uses to heal wounds, and when seeded with muscle cells, they act as a scaffold for the construction of healthy tissue.
Sensors that can detect the biomechanics of a pitcher's fastball have usually required test subjects to perform their windup in the lab. But now three engineering students have created a smart compression shirt that could track pitching mechanics out on the mound, Ecouterre reports.
