Carbon nanotubes could find use in improved bomb detection device

Along with flame-retardant clothing, flexible supercapitors and a stronger alternative to carbon fiber, carbon nanotubes may soon have yet another application. Led by Prof. Ling Zang, a team of researchers at the University of Utah has integrated the tiny tubes of carbon atoms into a prototype explosives sensor. It can also detect illegal drugs and toxic chemicals such as nerve gas, reportedly doing so better than currently-used technologies. Read More

Researchers develop new B12 testing kit

Vitamin B12 is vital to keep a nervous system healthy. Since it is found mainly in meat and dairy, it is common for people to associate B12 deficiency with vegans, who are aware of this issue (in Germany there's even a B12-enriched toothpaste) and often take measures to supplement. In fact, it is the general population of developing countries who are more likely to lack B12, and it is primarily for them that a team of Canadian researchers has developed a simple, cheap B12 test kit.

Clip-on Jolt Sensor vibrates when there's a risk of concussion

Heightened awareness of brain injuries and their enduring impacts has seen emphasis grow on immediate concussion testing. Indeed, if some time passes before detection, an additional blow to the already injured brain can have serious consequences. The team behind the Jolt Sensor is looking to make these assessments an instantaneous affair, with a sensor that clips onto an athlete's headwear and vibrates when they receive too heavy a knock.

New microchip promises to streamline and simplify diabetes diagnoses

For people who don't already know, here's the difference between type 1 and type 2 diabetes: the body produces little or no insulin in the case of type 1, and isn't able to utilize the insulin that it does produce in type 2. It's a significant difference, so it's important that patients are diagnosed correctly. Thanks to a new microchip developed by a team at Stanford University led by Dr. Brian Feldman, doing so could soon be quicker, cheaper and easier than ever before. Read More

Handheld HeatWave device produces 3D thermal maps in real-time

Thermal imaging has proven itself to be a useful adjunct to physical testing in areas including engineering, health, and agriculture. Until now, however, conventional 3D thermal imaging use has largely been restricted due to the specialized technical knowledge required to operate it and interpret the results. To address this, Australia's CSIRO has developed a prototype tool called HeatWave that is a lightweight, high-resolution 3D scanner that is claimed to be not only easy to carry, but easy to use as well.

Small, portable and cheap radiation detector is being designed for the public

Ever since the Fukushima nuclear reactor disaster, there has understandably been an upsurge in the sale of consumer radiation-detecting devices. Most of these gadgets are variations on the Geiger counter, in that they alert the user to the presence and level of radiation, but not the type of radiation – which is very important to know. Researchers at Oregon State University are hoping to address that situation by developing a handheld device that will additionally tell its users what type of radionuclide is creating the radiation, and whether it poses a risk.

New sensor to detect food-borne bacteria on site

It is estimated that every year in America there are around 76 million food-borne illnesses that result in 325,000 hospitalizations and over 5,000 deaths. One of the main causes is the disease "Listeria", which has the highest hospitalization (92 per cent) and death (18 per cent) rate among all food-borne pathogen infections. Now researchers at the University of Southampton say that they are trialling a device designed to detect these bacteria directly on food preparation services, and without the need to send samples away for laboratory testing.

Lasers could be used to detect drunk drivers

It used to be that the only way you could get a speeding ticket was if a police officer personally witnessed your overly-fast driving. Then photo radar came along. Well, when it comes to drunk driving, lasers could soon be the equivalent of photo radar. Polish researchers at the Military University of Technology in Warsaw have demonstrated how the high-intensity beams of light can be used to detect the presence of alcohol – even exhaled alcohol – in passing vehicles.
