NANA combines the potential of webcams and touchscreen computing

Researchers across a number of UK universities have developed a touchscreen computer system to help tackle the growing yet relatively unknown problem of malnutrition in older adults, and particularly those that live alone. The system combines specially-developed easy-to-use touchscreen software with the remote monitoring made possible by a simple webcam.  Read More

Scientists are working on creating a computer model of the honey bee's brain, which they p...

Honey bees are fascinating creatures. They live harmoniously in large communities, divided into different castes, with some of the worker bees heading out on daily expeditions to gather nectar and pollen from flowers. Already, a study has suggested that the efficient method in which bees visit those flowers could inspire the improvement of human endeavors such as the building of faster computer networks. Now, scientists from the Universities of Sheffield and Sussex hope to build a computer model of the honey bee’s brain, with the ultimate hope of using it to control tiny autonomous flying robots.  Read More

Clothing treated with the CatClo laundry additive can remove nitrogen oxides from the air

A laundry additive created by researchers from the University of Sheffield and the London College of Fashion turns clothing into a photocatalytic material that can help remove nitrogen oxides (NOx) from the air. One of the most prominent air pollutants, nitrogen oxides are emitted from the exhausts of ICE-powered vehicles and aggravate asthma and other respiratory diseases. The researchers claim one person getting around town in clothing treated with the additive for a day would be able to remove roughly the same amount of nitrogen oxides produced by the average family car each day.  Read More

Researchers have developed a system that uses a pressure wave to reliably and rapidly loca...

Tracking down the source of a leak in water pipes can be a tricky business. Current techniques rely on acoustic sensing with microphones often used to identify noise resulting from pressurized water escaping the pipe. In plastic pipes in particular, that noise can fall away quickly, making leak detection difficult and time consuming. Researchers at the University of Sheffield claim to have developed a much more accurate system that locates leaks by sending a pressure wave along the pipe that sends back a signal if it passes any anomalies in the pipe’s surface.  Read More

Researchers at the University of Sheffield have created what sounds impossible - even nonsensical: an experimental electron microscope without lenses that not only works, but is orders of magnitude more powerful than current models. By means of a new form of mathematical analysis, scientists can take the meaningless patterns of dots and circles created by the lens-less microscope and create images that are of high resolution and contrast and, potentially, up to 100 times greater magnification.  Read More

Jump rope and similar kinds of games will be used to develop games for Nintendo's Wii cons...

The development of Wii computer games, where handsets take the place of real equipment from sports, such as tennis, golf or baseball, has been very successful. Now, a unique and ambitious collaborative project in the United Kingdom looks set to convert popular skipping and clapping playground games into Wii-styled prototype games.  Read More

A robotic 'ferret' will help customs find drugs, weapons and people hidden in freight cont...

It won’t be cuddly, but it’ll certainly be efficient. The University of Sheffield is developing what it calls a cargo-screening ferret that uses a combination of laser and fiber-optic technology to sniff out the tiniest traces of drugs, weapons, explosives and even illegal immigrants.  Read More
