A University of Dundee research team led by Prof. Mike MacDonald has demonstrated that both levitation and twisting forces can be applied to an object by application of ultrasonic beams. This latest breakthrough is part of a wide-ranging U.K. research effort to develop a device not unlike the "sonic screwdriver" made famous by the TV series Doctor Who.  Read More

When someone has gallstones, treatment typically involves the removal of their gallbladder. This is usually done laparoscopically, in a procedure known as a cholecystectomy. A group of scientists from the Second People's Hospital of Panyu District and Central South University in China, however, have created an endoscope that they say is able to locate and remove gallstones while leaving the gallbladder intact.  Read More

Prof. Tim Leighton and Dr. Peter Birkin with their ultrasonic nozzle

In many industries, such as health care, food preparation and electronics manufacturing, cleanliness is of the utmost importance. It’s important enough that huge quantities of water are used – and left tainted – in order to remove contaminants. While some groups have concentrated on creating better cleansers, a team of scientists from the University of Southampton have taken a different approach. They’ve created an ultrasonic tap nozzle, that allows the water itself do a better job at cleaning. The better that a given amount of water is able to clean, the less of it that needs to be used.  Read More

Silver is a known killer of harmful bacteria, and has already been incorporated into things such as antibacterial keyboards, washing machines, water filters, and plastic coatings for medical devices. Now, scientists have added another potential product to the list: silver nanoparticle-impregnated “killer paper" packaging, that could help keep food from spoiling.  Read More

Sonic screwdrivers may soon be more than props at Doctor Who conventions (Image: R. Steven...

The sonic screwdriver has proven an indispensable piece of equipment for Doctor Who when battling Daleks, Cybermen and the Master. The fictional tool is capable of opening just about any lock known to man - or alien - and can fix a damaged TARDIS in a matter of seconds. Now engineers at Bristol University say a real-life version of the sci-fi screwdriver could be created that would use sonic technology to open locks and undo screws ... just don't expect to see one under the Christmas tree this year.  Read More

Could this talking dog collar also help keep Rover safe from nasty fleas?

It’s common knowledge that owning a pet can have many health benefits. A pet can reduce stress and anxiety, help to combat loneliness and even encourage you to exercise. So it’s no wonder that we want to keep them safe from harm. This pet collar from Riddex apparently protects your furry friend in two ways – if your pet goes missing, it literally “tells” people how to contact you and it also uses safe ultrasonic pulses to repel fleas.  Read More
