A real “Sonic Screwdriver”

It looks like a group of physicists have taken inspiration from Doctor Who and created a “sonic screwdriver”. How cool is that? So far, it has managed to lift a rubber disk using ultrasound, which isn’t quite as good as The Doctor, but he IS about 900-odd years old!

The Dundee researchers used energy from an ultrasound array to form a beam that can both carry momentum to push away an object in its path and, by using a beam shaped like a helix or vortex, cause the object to rotate.

Now, that sounds pretty cool as it is, but what makes it even more interesting is the potential medical applications using ultrasound. Ultrasound is already used, for example, to deliver chemotherapy into brain cancer cells, or in dentistry for cleaning teeth. The head of the group that made this screwdriver claims it could be used for even more targeted delivery or precise cellular manipulation.

I bet The Doctor would be interested.
