Acoustic tractor beams use the power of sound to hold particles in mid-air, and unlike magnetic levitation, they can grab most solids or liquids. For the first time University of Bristol engineers have shown it is possible to stably trap objects larger than the wavelength of sound in an acoustic tractor beam. This discovery opens the door to the manipulation of drug capsules or micro-surgical implements within the body. Container-less transportation of delicate larger samples is now also a possibility and could lead to levitating humans.

Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a 100000X faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories. The new research results will appear as the cover story on 19th January in the renowned scientific journal Science.
Integrated Si photonics incorporates the essence of the two pillar industries of “microelectronics” and “optoelectronics”, which is expected to bring new technological revolution in a variety of fields such as communication, sensing, lighting, display, imaging, detection, etc. Si lasers are the key to achieve integrated Si photonics. However, the optical gains of Si are lower than those of III-V compound semiconductors by one order of magnitude or two, due to its indirect bandgap feature...Read More
Engineers worldwide have been developing alternative ways to provide greater memory storage capacity on even smaller computer chips. Previous research into 2D atomic sheets for memory storage has failed to uncover their potential – until now...Read More
