A robotic arm is the key to a radical new stroke treatment, helping patients regain upper body movement.
Melbourne researchers have developed a device that helps stroke patients learn to use their bodies again by tracking their movements while performing exercises. The arm movements can be displayed on a computer screen, and the activities turned into a game.
“The patients enjoy using the robot because it’s like playing computer games,” says Associate Professors Denny Oetomo, who is working with Ying Tan, and a team at The University of Melbourne and Royal Melbourne Hospital.
Imagine printing your own room lighting, lasers, or solar cells from inks you buy at the local newsagent. Jacek Jasieniak and colleagues at CSIRO, the University of Melbourne and the University of Padua in Italy, have developed liquid inks based on quantum dots that can be used to print such devices and in the first demonstration of their technology have produced tiny lasers. Quantum dots are made of semiconductor material grown as nanometre-sized crystals, around a millionth of a millimetre in diameter. The laser colour they produce can be selectively tuned by varying their size.
High tech cling wraps that ‘sieve out’ carbon dioxide from waste gases can help save the world, says Melbourne University chemical engineer, Colin Scholes who developed the technology. The membranes can be fitted to existing chimneys where they capture CO2 for removal and storage. Not only are the new membranes efficient, they are also relatively cheap to produce. They are already being tested on brown coal power stations in Victoria’s La Trobe Valley, Colin says. “We are hoping these membranes will cut emissions from power stations by up to 90 per cent.”
