First of all, how can non-invasive surgery even be possible? After all, even in the case of minimally-invasive laparoscopic surgery, small incisions are still made in the skin. Nonetheless, that’s just what scientists from the University of Michigan are proposing. They believe that it could be achieved by using a beam of sound, which would be emitted through the skin to a highly-focused point within the body – and they’ve already created such a beam and used it.

While promising vaccines and genetically-engineered mosquitoes are providing hope in the fight against malaria, it currently remains a major and potentially life-threatening problem in tropical and subtropical regions around the world. These regions are also hot and sticky, making LG's introduction of an air conditioner that it claims actively repels mosquitoes as it keeps the house cool a seemingly obvious blending of technologies.

Given that most bats hang out (literally) in caves and other secretive places, and only fly at night, they’re not the easiest of creatures to study. Tel Aviv University zoologist Dr. Yossi Yovel, however, has a plan. He is currently establishing the world’s first bat colony to be born and raised in captivity. Although the resulting “roost” will be based out of a research facility, the bats will be free to come and go to hunt for insects in the surrounding environment. As they do so, some of them will be equipped with high-tech sensors designed to gather information on their behavior. Read More
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.

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.

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
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.

The fight for more environmentally-friendly ways of living continues and this time household appliances are getting a boost from innovative French manufacturer De Dietrich, which has come up with an efficient new way to clean the dishes - less power, recycled water and detergent-free. Read More
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.
