Comments Off on Acoustic tractor beams could allow humans to levitate in the near future

Researchers from the University of Bristol are taking us into the future with a new discovery that could pave the way for human levitation. The powerful new technology uses tractor beams of sound to levitate liquids or even large objects – like a human beings – in mid-air. It’s like something straight out of a science fiction movie. Up until now, acoustic tractor beams could only lift tiny objects – anything larger than the wavelength would become rapidly unstable. But this new technology utilizes acoustic vortices that shift rapidly to hold and move objects. It’s kind of like trapping an object in a powerful tornado of sound, with a silent eye and loud sound on the exterior. By quickly changing the rate of rotation, scientists can stabilize the tractor beam and even manipulate it to hold larger objects.

This was only thought to be possible using lower pitches making the experiment audible and dangerous for humans,” said Senior Research Associate Dr. Mihai Caleap. + Physical Review Letters Via Phys.org Images via Physical Review Letters

Tractor beams may soon be no longer fictional tools under the command of starship captains, as a team of researchers at the UK’s University of Bristol has managed to create a simple tractor beam out of easily obtainable parts. Check out the video above to learn how you can build your own for just over $70. https://youtu.be/6YV0lou4L4c According to the University of Bristol , the concept for this tractor beam is much simpler than a recent sonic tractor beam that uses sound waves to trap and manipulate tiny objects. According to the recent paper published in Applied Physics Letters, this tractor beam design uses just one electric signal and a passive wave modulator. As the University of Bristol notes: “The passive wave modulator is a type of acoustic lens that can alter the transmitted or reflected waves. The research team’s passive wave modulator can be made in various different ways. In one example it’s a collection of tubes with different lengths and in another it’s a carefully contoured surface. In both cases it can be 3D-printed using an off–the-shelf printer. Using a single waveform a static tractor beam can be created. If two waveforms are used then up and down manipulation of objects can be achieved.” Related: This revolutionary new paper battery is powered by bacteria According to research assistant and lead author of the paper, Asier Marzo, “The technique can generate an acoustic tractor beam using only a single electrical signal, this will reduce the cost and complexity of tractor beams making them a more affordable technology for manipulating and analyzing levitated samples. With our new research now everyone can have an acoustic tractor beam.” The device is so simple, the university has released a YouTube video showing people how they can build their own tractor beam at home for just over $70. That’s a far cry from previous tractor beam technologies, which required phased arrays of more than 50 sound channels, with each made up of a signal generator and an amplifier.

Comments Off on George Lucas selects Los Angeles to host $1 billion art museum

Apparently, the force is much stronger in Los Angeles than it is in San Francisco. Star Wars creator and beloved filmmaker George Lucas recently announced he has chosen the City of Angels as the location for the $1 billion Lucas Museum of Narrative Art . Although the project is very much in the beginning phases, Lucas has tapped Chinese architectural firm Mad Architects to lead the design, which, at first glance, looks like it will be a futuristic design surrounded by acres of sprawling green space . The much-anticipated museum will be located in L.A.’s Exposition Park, holding court along side the California Science Center , Natural History Museum of Los Angeles County and California African-American Museum. It will also be adjacent to the director’s alma mater, the University of Southern California. Related: Quirky Pinocchio-themed museum looks like it came out of Geppetto’s workshop As far as the content of the museum goes, the one-of-a-kind collections will be divided into three categories, namely narrative art, the art of cinema and digital art. The exhibitions will include everything from fine art and popular art to illustrations and comics, and of course, props and storyboards from the director’s iconic movies. According to Lucas, the museum will revolve not only around the art itself, but the idea of creating something new and unique, no matter what medium, “The whole point of this museum is to stimulate the imagination…to open eyes to the possibilities of creating art.” + Lucas Museum of Narrative Art + MAD Architects Via Forbes Images via Lucas Museum of Narrative Art

Comments Off on Scientists Discover a 400 Mile Canyon Below Greenland Ice Sheet

Most of Greenland is covered in a thick sheet of ice , but scientists have just discovered another vast canyon beneath the 460 mile glacier. Headed by Jonathan Bamber at the University of Bristol , the study concludes that a canyon twice the length of the Grand Canyon lurks beneath a whopping two miles of ice. Scientists think that the canyon was carved by an ancient river system, a new discovery that has intrigued research teams to further investigate what lies below major continental ice sheets .

A team of scientists from the Universities of Cambridge and Bristol have discovered that velcro-like cells on plant petals help bees to keep their grip while collecting pollen and prevent them from being blown away by the wind. The research was published this week by the British Ecological Society’s journal  Functional Ecology .

Comments Off on New Magnetic Soap Could Clean Up Oil Spills Quickly and Efficiently

With the 2010 Gulf of Mexico oil spill still impacting the local environment and the recent Costa Concordia accident threatening to leak diesel off the Italian coast, there has never been a better time to research new ways of cleaning up disasters such as these. Luckily, the University of Bristol just developed a soap that responds to magnetic fields – meaning it could be used to scoop up large amounts of oil from water without leaving behind potentially harmful chemicals.
