Brit boffins build 'tractor beam' out of sound Researchers from Spain and the British city of Bristol have found a way to move objects using sound. In their Nature Communications paper, the six researchers explain that “Sound can levitate objects of different sizes and materials through air, water and tissue ... This allows us to manipulate cells, liquids, compounds or …
The paper and video both describe small plastic beads being controlled, so this is obviously not something that is going to be used to draw the Millennium Falcon into the Death Star any time soon.
Good luck getting that to work in SPAAAAAAAAACE....... ever.
Sounds (scuse pun) more like a sonic screwdriver prototype to me.
I agree. There is no sense in which it is holographic, and they use fake photos to publicise it, the ghostly fingers, there is no way it would make that image.
An interesting contraption, but their claims are bullshit. How is it supposed to work anywhere except, perhaps in the air?
Brian Blessed can move things with sound, especially people, many of whom move away with alacrity.
Joking aside, this is a very interesting development, and well done to the acousto-boffins! This might also be an interesting project to simulate for our students. I'll give the paper a thorough read
A.M. [Pamplona .ac] and B.W.D. [Bristol .ac] designed, developed and implemented the algorithms and simulations; A.M. and S.A.S. [Bristol .co] measured the acoustic slices; A.M [Pamplona .ac] and D.R.S. [Sussex .ac] measured the spring constants; A.M. [Pamplona .ac] conducted the rest of the experiments and wrote the paper; all the authors contributed to the discussion and edited the manuscript.
tl;dr Pamplona and Bristol created the algorithms, Sussex helped measure them.
There are some theories in the Ancient Aliens hypothesis that sound was used in the is the distant past to move large objects using cone shaped items.
Not that I ascribe to these, but I like to keep an open mind regarding the unknown.
It's got to have more uses than most of the sound related research of the last few years, which seems to be aimed at making large groups of people shit themselves or somesuch...
Very clever stuff, however doing this in air is one thing, doing this in a non-homogenous medium like a human body will be even more impressive. I saw a demo of acoustic levitation some time ago, this is the next step on, looking forward to seeing how far they can go with the idea.
If your kidney stones have made it to the bladder, they don't need treatment in general as they'll happily pass out of your urethra (tube from bladder to the outside). This is cos it is much larger than your ureters (tube between kidneys and bladder) in diameter. It's when stones are stuck here that there is pain. And using ultrasound to break them up is helpful, for the smaller ones (the larger ones it's too difficult and cold steel, aka surgery, is still indicated).
Is my understanding. Not a urologist though.
word, normally happen when some like this is happening

get a free sonic visualizer, you don`t need any bass tubes to move ping pong balls etc, hardcore is the best music to use, other music is made by nerds, who just talk the talk, then end up using samples because they star in mixmag : https://www.youtube.com/watch?v=2WtpAnzlmaE
