Welcome to the Pulse, brought to you by MDT TV. Today, we’re patenting new biomaterial to make artificial bones, creating pain-free prosthetics, using ultrasound waves to improve your mood, and using magnets to steer stem cells. This episode features:

  • Scientists have patented a new biomaterial that facilitates generating bone tissue, or artificial bones, from umbilical cord stem cells.
  • University of Washington engineers aim to ease the discomfort often experienced by those with prosthetic legs. They have developed a device that tracks how much a person's limb swells and shrinks when inside the socket.
  • University of Arizona researchers have found that ultrasound waves applied to specific areas of the brain appear able to alter patients' moods.
  • Magnets could be a tool for directing the healing powers of stem cells to treat conditions such as heart and vascular disease.
