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.

Handheld device detects and analyzes soil contamination within seconds

Contamination of soil from petroleum spills is an ongoing problem that threatens to adversely affect the environment and the health of the people in it, so rapid testing of sites is a pressing issue. However, with laboratory samples and results requiring at least a number of days turn around, particularly in remote locations, rapid analysis is not usually possible. RemScan is a self-contained, hand-held hydrocarbon contamination testing device designed to address this problem. Recently released on the US market, the device is capable of testing many hundred samples a day, providing data on the spot, within seconds, and completely without the need of a laboratory. Read More

Object detection software to enhance driver awareness, improve safety

When it comes to driver awareness, we all know how hard it can be to keep an eye on every pedestrian and moving vehicle in our vicinity, particularly when driving in a busy city area. Couple this with the upcoming Kids and Transportation Safety Act in the US that dictates that all cars built from May 2018 onwards must be fitted with rear view cameras as standard, and it becomes doubly important that on-board vehicle cameras are used to their best advantage. To help in this regard, Fujitsu Semiconductor Limited is set to introduce software that assists in detecting and identifying cars, people, and other moving objects and alerts the driver of their position and direction of travel.

Ultrasound device could help detect cause of heart attack and stroke

While existing ultrasound technologies are able to identify plaque buildup on artery walls, determining when that plaque is at risk of breaking off, resulting in a heart attack or stroke, has proven a more complicated task. A team of researchers from North Carolina State University has now developed a dual-frequency ultrasound device that could help identify so-called vulnerable plaque and enable a more accurate diagnosis for at-risk patients.

Tired? Angry? Your car knows how you feel

Ever experienced road rage? Someone cuts you off while you’re trying to merge and next thing you know you’re tailgating them like a NASCAR driver at Fontana trying to get a slingshot off the bank. Then they hit the brakes … "screech-crash-bang" … there goes your platinum rating with the insurance company. What if an on-board emotion detection system could tell that you were getting annoyed and intervene? PSA Peugeot Citroen has teamed up with the Swiss Federal Institute of Technology to develop an emotion detection system designed to recognize signs of irritation and fatigue in a driver’s facial expressions.

Toxin-detection system inspired by turkeys

Turkeys may not be everyone's idea of beautiful birds, but they certainly have colorful skin on their heads. What's more, that skin changes color with the animal's mood. Scientists at the University of California, Berkeley, have now copied the process by which those color changes occur, and used it to create a biosensor that could be used to detect airborne toxins.

DNA clamps could stop cancer in its tracks

Scientists have developed a special DNA clamp to act as a diagnostic nano machine. It's capable of detecting genetic mutations responsible for causing cancers, hemophilia, sickle cell anemia and other diseases, more efficiently than existing techniques. Not only can the clamp be used to develop more advanced screening tests, but it could also help create more efficient DNA-based nano machines for targeted drug delivery. Read More

Lung cancer breath test to be trialed at UK pharmacies

With lung cancer survival rates greatly improved by early detection, we've seen a number of efforts to develop a better way to detect the disease in its early stages. Various breath test devices have been developed by a number of companies around the world, and now a team from the University of Huddersfield in the UK plans to trial such a device to identify lung cancer in pharmacies.
