Known as "frozen smoke" because of their milky translucent appearance, aerogels are among the world's lightest solid materials. Consisting of 99.8 percent air, they're highly heat-resistant and are an excellent form of insulation. Now, scientists at the National University of Singapore (NUS) have used paper waste to create one.
A new robotic glove for hand rehabilitation swaps conventional rigid electromechanical components for soft fabric with embedded actuators (motors). The glove, dubbed EsoGlove by its National University of Singapore creators, is meant to conform to natural hand movements and is lightweight, portable, and intuitive enough that patients should be able to easily carry out their rehabilitation exercises in their own homes.
This year, we've seen a number of important developments in the race to bring personal flyers to market. A team of flying enthusiasts from Hungary took to the skies in a proof of concept tricopter named Flike in March, Malloy Aeronautics announced plans to develop its Hoverbike for the US Department of Defense at the Paris Air Show in June, and the JB-9 made its maiden flight around the Statue of Liberty just last month. Now a team of students from Singapore has joined the fray with a battery electric multicopter called Snowstorm that's being designed for recreational flying.

surface. That's why scientists at the National University of Singapore
have developed an alternative – water-quality-monitoring robots that
look like swans.
