Researchers in China plan on creating matter out of absolutely nothing by using an ultra-powerful laser to overcome spacetime itself at the quantum level. While we shouldn’t expect the laser to manifest a hot cup of Earl Grey tea out of nowhere, the experiment is expected to produce elementary particlesread more
Fans of space sagas Star Wars and Star Trek will be very familiar with "tractor beams," the projected force-fields utilised by spaceports, planetary bases, space stations, and star-ships to lock onto crafts and guide them to a safe designated landing site.
New research conducted at Dundee University in Scotland has now used ultrasound energy to create a "tractor beam" with properties similar to its science-fictional equivalent.
During the study, which was published in the journal APS Physics, scientists managed to remotely pull a hollow triangular object towards the energy source, push it away and also rotate it.

Will brain control (NOTE: Subscribers can still listen to this show) someday make us all obedient servants? In the quest to understand how the brain turns sensory input into behavior, scientists have used precisely-targeted lasers to take over an animal’s brain, instruct it to turn in any direction they choose, and even to implant false sensory information, fooling the animal into thinking food was nearby.
