Soft Robot Fingers Collect Delicate Coral

Most deep sea robotic manipulators are constructed from hard materials that are not geared to collect fragile coral. Researchers at the Wyss Institute, Harvard Paulson School, and City University of New York have developed a soft robotic gripper that can safely handle delicate specimens, including biological specimens on deep reefs.

Researchers Advance Propulsion Toward Low-Carbon Aircraft

Just as hybrid or turboelectric power has improved fuel efficiency in cars, boats and trains, aeronautical engineers are exploring how planes can be redesigned and configured with electrical power. One of NASA’s goals is to help the aircraft industry shift from relying solely on gas turbines to using hybrid electric and turboelectric propulsion in order to reduce energy consumption, emissions and noise.

Lightweight, Strong Metal Could Make Airplanes More Energy Efficient

Researchers have created a lightweight, but very strong, structural metal made of magnesium because it is a light metal with two-thirds the density of aluminum, is abundant on Earth, and is biocompatible. It was mixed with silicon carbide nanoparticles into a molten magnesium-zinc alloy that uniformly dispersed and stabilized the nanoparticles, making a super-strong and lightweight metal.

NASA Flies Drones in Aircraft Noise Test

Microphones strung together on an unmanned aircraft system runway were used to record the sounds of remotely piloted aircraft flying overhead as part of a NASA project to measure full-scale aircraft noise. The work is part of research to reduce airplane noise and make the skies more environmentally friendly, especially around airports.
