Researchers create a way to cook using lasers

Researchers create a way to cook using lasers

Researchers from Columbia University have created a system that can cook food using lasers and leverages 3D printing technology to assemble foods. Researchers on the Digital Food team from the Creative Machines Lab have been working to build an autonomous digital personal chef. The team says that printers can produce ingredients at a millimeter precision, but there was no heating method with the same degree of resolution.

Japanese researchers design linear nanomotors controlled using light

Researchers from the Institute of Industrial Science, University of Tokyo, have designed linear nanomotors that can move in controlled directions using light. Researchers say that the work opens the door for new microfluidics, including lab-on-a-chip systems with optically actuated pumps and valves. The researchers point out that powering and controlling a motor smaller than a single bacterium precisely is very difficult.
