Ankle exoskeleton makes running easier
Researchers find that a motorized device that attaches around the ankle and foot can drastically reduce the energy cost of running. Running is great exercise but not everyone feels great doing it. In hopes of boosting physical activity - and possibly creating a new mode of transportation - engineers at Stanford University are studying devices that people could strap to their legs to make running easier.

More efficient, longer-lasting solid oxide fuel cells
More efficient, longer-lasting solid oxide fuel cells
Researchers at EPFL have developed a novel way to increase fuel-cell efficiency and lifespan, using a recirculation fan driven by a steam turbine that runs on steam-lubricated bearings. Solid oxide fuel cells, or SOFCs, are devices that produce both electricity and heat by oxidizing a fuel such as natural gas or biogas.

Overlooked arch in the foot is key to its evolution and function
A long-overlooked part of the human foot is key to how the foot works, how it evolved, and how we walk and run, a Yale-led team of researchers said. The discovery upends nearly a century of conventional thinking about the human foot and could open new avenues to explore in evolutionary biology as well as guide new designs for robotic and prosthetic feet, said the study team.

Scientists finally confirm a 50-year-old theory in mechanics
An experiment by EPFL researchers has confirmed a theory that has been used in mechanics for over half a century - despite never having been fully validated. The team could now use the theory in bolder and more innovative ways in their quest to develop ever better energy systems. Some theories are widely used even though they have never been experimentally validated.
