Sound can be used to control the flow of air over an aircraft’s wing greatly boosting its lift, according to Ian Salmon, a Sydney aerospace engineer who is working on applying this idea to a new generation of light aircraft.
Ian has developed a technique whereby a wing is covered with flexible plastic panels which vibrate when an electric current is passed through them, and produce sound. At a carefully selected frequency, the air passing over the wing can be made to remain more closely attached, increasing the wing’s efficiency.
Ian presented his work to the public and media as part of Fresh Science, a national program that highlights the work of early-career researchers. One of the Fresh Scientists will win a trip to the UK courtesy of the British Council to present their work to the Royal Institution

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
