Often grouped in wind farms, HAWTs provide significant amounts of energy for local communities. One drawback to HAWTs is the large space they take up, needing to be placed far

The exosuit’s soft textiles strategically position the actuating cables that assist with the ankle motion at the back of the lower legs, and, through additional straps, transfers energy produced at the ankle to the front of the hip to also assist with the gait’s hip motion.

The advance could speed the development of powerful

As the twine coils and uncoils, the button spins at a dizzying speed. Now, using the same mechanical principles, Stanford bioengineers have created an ultra-low-cost, human-powered centrifuge that

The schematic at left shows the design for an experimental transistor made of a semiconductor called beta gallium oxide, which could bring new ultra-efficient switches for applications such as the power grid, military ships and aircraft. At right is an atomic force microscope image of the semiconductor. (Purdue University image/Peide Ye) Researchers have demonstrated the

“There’s a close correspondence between what you need for communication in rapidly changing networks and information processing in the brain,” professor Nancy Lynch says. “We’re trying to find problems that can benefit from this distributed-computing perspective, focusing on algorithms for which we can prove mathematical properties.”Image: MIT News Study suggests computational role for neurons that
