Sonic "invisible scalpel" could be used for non-invasive surgery

By - December 20, 2012 1 Picture
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.

LG mosquito-repelling air conditioner aims to help reduce malaria cases in Africa

By - November 22, 2012 2 Pictures
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.

Bats to be equipped with GPS, microphones and possibly cameras

By - July 10, 2012 1 Picture
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

New gallstone-removing endoscope promises fewer gallbladder removals

By - January 18, 2012 2 Pictures
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.

Ultrasonic nozzle promises better cleaning with less water

By - November 14, 2011 1 Picture
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.

Sonic screwdriver may become fact rather than fiction

By - December 7, 2010 1 Picture
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.

A pet collar that talks and keeps fleas at bay?

By - September 23, 2009 1 Picture
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.
