A team of engineers at The University of Texas at Austin say that they have built the smallest, fastest, and longest-running synthetic motor to date. This nanomotor, which could fit inside a human cell, is an important step toward developing miniature machines that could one day move through the body to...

A team of microsystems engineers and neurosurgeons at the University of Freiburg in Germany are working to develop a new implantable cuff equipped with electrodes that, they say, can lower blood pressure without causing side effects. While doctors usually prescribe drugs against high blood pressure, in...

A robot developed by researchers at the at the Learning Algorithms and Systems Laboratory (LASA) at EPFL (Ecole Polytechnique Fédérale de Lausanne, Switzerland) can react on the spot, grasping flying objects thrown at it with complex shapes and trajectories in less than five hundredths of a second.

Move over Iron Man! There’s a new engineering superhero who’s part bionic, able to change his height, and scale vertical rock and ice walls with a simple change of leg prosthetics that he designed himself. Not only that, but he designs bionic limbs for others, too.

A team of researchers at the University of Pittsburgh have developed a tiny microchip that, they say, may save joint implants before they’re overcome by infection. This chip, which is engineered to detect pH levels in the body, can alert doctors to encroaching bacterial infection, which causes acidosis, a...

An international team of engineers from Penn state University, University Park, PA, and King Abdullah University of Science and Technology, Saudi Arabia, have discovered that saliva-powered micro-sized microbial fuel cells can produce minute amounts of energy—enough to run on-chip applications, they say. This...

A team of scientists at the University of Cincinnati, OH, says that an electrical stimulus can promote the growth of blood vessels and help to speed healing in diabetic ulcers and other hard-to-heal chronic wounds. Their research examines the best stimulus parameters, such as frequency and magnitude,...

A new technique to purify blood uses a nanofiber mesh, which could be useful as a cheap, wearable alternative to kidney dialysis, say a team of researchers at the International Center for Materials Nanoarchitectonics, National Institute for Materials Science in Ibaraki, Japan. The mesh could be incorporated...
