Fact: no one is driving this car (Photo: Gizmag)

Gizmag took a trip to Gothenburg to see six pieces of autonomous driving technology demonstrated by Volvo on Tuesday. A self-parking car and a car that drives itself (albeit under certain conditions) were among the tech on display, rounded out by new detection systems for animals, pedestrians at night, road edges and barriers, as well as a behind-the-scenes car-to-car communication system. All are positioned as pieces of safety technology, Volvo's goal being that no one will die or be seriously injured in a new Volvo come 2020. But it's also clear that Volvo is deadly serious about full autonomy, and given that some of the tech Gizmag saw will be on the market next year, a driverless future feels closer today than it did when the week began. But it's a future that will take some getting used to …  Read More

Ultrasonic sensors could help detect air leaks on the ISS (Photo: NASA)

In space, no one can hear you scream, but you can hear an air leak. In old science fiction movies, air leaks on spaceships and stations reveal themselves as convenient holes to slap a patch on, but on the complex International Space Station (ISS), it isn't that simple. NASA is working on a new system for detecting the ultrasonic noise of an air leak quickly before it turns into a dangerous race against time.  Read More

Using a collection of sensors placed all over the body, the SpiderSense suit detects objec...

In the Spider-Man comics and movies, the famous hero's "Spider Sense" warns him of incoming danger, which proves to be just as important a superpower as slinging webs and climbing walls. Now a group of researchers at the University of Illinois in Chicago may have found a way to replicate such superhuman perception that doesn't involve any radioactive spiders. Using a collection of sensors placed all over the body, the group has designed a "SpiderSense" suit that detects objects in the environment and warns the wearer when anything gets too close.  Read More

The military use of radar has always had a yin-yang dynamic – as new forms of radar are developed, so too are new ways to jam them. A team of physicists at the University of Rochester has discovered how to defeat the latest active radar jamming methods by taking advantage of the quantum properties of photons. While this new anti-jamming technology cannot remove the false information, it provides an immediate alert that false information is being received.  Read More

A team of UCSB researchers have mimicked the anatomy of a dog's nose to build a highly eff...

Combining nanotechnology and microfluidics, researchers at UC Santa Barbara have created a high-performance detector that draws inspiration from the anatomy of a dog's nose to accurately identify substances – including explosives and narcotics – from very small concentrations of airborne molecules.  Read More

Clearing explosives is a major operation and removing the deadly residue of over a century of warfare is a never ending task. The problem is that before you can remove explosives you have to find them. That isn’t always easy – especially underwater, so Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) has developed a new sensor that uses high-temperature planar gradiometers to seek out explosives in the sea.  Read More

A consumer laser pointer has been used to create a small, inexpensive Raman spectrometer (...

Hand-held laser pointers can now be used for something else besides doing presentations, projecting images of microorganisms, and disabling satellites. Next week, a group of scientists from Israel’s Ben-Gurion University of the Negev will be presenting a compact device that they created, which uses a garden-variety green laser pointer to detect dangerous substances such as explosives.  Read More

Researchers from Nagoya University and Fujitsu are set to begin field trials of an automat...

Researchers from Nagoya University and Fujitsu have spent the last few years developing an automated detection system that alerts the recipient to possible phone phishing scams. After successful simulation testing, the team has now announced plans for household field trials.  Read More

Under UV light, the nanofibrous film detects trace 2,4-DNT explosive buried in a flower po...

Engineers at the University of Connecticut (UConn) have developed a fluorescent nanofibrous film capable of detecting ultra-trace levels of explosive vapors from landmines and other buried explosive devices. In the presence of explosive molecules, the film’s fluorescence is suppressed when exposed to ultraviolet (UV) light. In this way, the lightweight film, which is similar to paper, could be rolled out over suspect areas to mark the location of explosive devices.  Read More

IMASS can sample and detect eight substances simultaneously (Photo: BBI International)

In war and disaster, ignorance can be deadly, so it’s important that soldiers and first responders get the information they need as quickly as possible. Dr. Peter White, a scientist with Britain's Ministry of Defence, has invented a handheld device that makes collecting samples and carrying out tests in the field much simpler and faster than previously possible. Developed at the Defence Science and Technology Laboratory (Dstl), the Integrated Multiplex Assay and Sampling System (IMASS) can collect samples of and detect eight different substances simultaneously.  Read More
