  • Biodegradable Transistors

    Zhenan Bao, an associate professor of chemical engineering, and Christopher Bettinger, a postdoctoral fellow, show off the biodegradable electronics they make in their lab at Stanford University.

  • Helping Hands

    This robotic rehabilitation device from Northeastern University uses electrically responsive fluid in its gears to adjust resistance as a patient performs gripping exercises. A patient who is recovering from a stroke, for example, could use the device to strengthen motor control as she plays a maze game.

  • A Robotic Gait Corrector

    This device, one of several robotic rehabilitation tools from Northeastern University, adjusts a person’s gait as he walks.

  • Robo-Rehab for MRIs

    This robotic rehabilitation device from Northeastern University is designed to let patients exercise hand and forearm muscles while in an MRI machine. Using a stroke-rehabilitation device in an MRI might let a doctor see the effects of the exercise on the brain.

  • Backpacks for Cells

    In the first part of this time-lapse video, an immune cell equipped with a tiny polymer backpack gambols across a microscope slide for some six hours before getting stuck. In the second part of the video, cells with backpacks full of magnetic nanoparticles are tugged toward a magnet, while cells without backpacks stay put.
