A European Space Agency experiment aboard the International Space Station suggests that space travelers may have less to worry about when it comes to radiation ... thanks to a phantom. Called the Matroshka, the "phantom" is a plastic mannequin that is the key component of the first comprehensive study of the effects of radiation on astronauts on long-term space missions that indicates that the hazard may not be as severe as previously thought.  Read More

Pulsar uses nuclear magnetic resonance to differentiate between horse meat and beef

Although eating horse meat is normal in many parts of the world, in other places, such as Britain, it rates almost on the same level as eating the family dog. So when it was discovered last year that horse meat was being passed off as beef, it literally put a lot of people off their dinner. To prevent a repeat of the episode, the Institute of Food Research (IFR) in Norwich and Oxford Instruments have developed a portable detector that can differentiate between horse meat and beef in about 10 minutes, yet is inexpensive and simple to use.  Read More

AirGuard is designed to catch tobacco and marijuana smokers in the act, and ratting on the...

While it's not against the law to smoke cigarettes in most parts of the world, there are still a lot of places where smoking is prohibited – workplaces, hotels, public housing, college dorms, jails – and a whole lot of smokers who still like to sneak in a cheeky one on the sly. That could become a lot more difficult with the release of the AirGuard, a sophisticated smoke detection unit that can either be hand held or fixed to a wall, and that can send out a Wi-Fi alert when tobacco or marijuana smoke is detected.  Read More

A new app can help turn your smartphone into a detector of cosmic rays thought to emanate ...

There are all sorts of apps available for smartphones to show atmospheric phenomena like wind speed, temperature, and rainfall along with other observations for tides and phases of the moon. But how about something really cool like an app for measuring the amount of interstellar cosmic radiation hitting the earth? A professor of physics from the University of Wisconsin thought that would be cool as well, and created an app to turn your smartphone into a cosmic ray detector that works in a similar way to those instruments found in high-tech observatories and mega-expensive laboratories.  Read More

The ultra-thin terahertz band light detector can see just below the surface of clothing, b...

A new prototype light detector uses graphene's light-absorbing properties to see in a broad band of light wavelengths that includes terahertz waves. These fall between the microwave and infrared bands, thereby making it possible to look just beneath the surface of opaque objects such as skin and plastic.  Read More

The Zhong group from U-M responsible for pioneering a new graphene-based photodetector (Ph...

Thermal imaging has already found its way onto smartphones, but a team of researchers from the University of Michigan (U-M) have gone even further with the creation of an ultrathin graphene-based light detector. Being only slightly thicker than two sheets of graphene, the approach has the potential to put infrared heat detecting technology into a contact lens.  Read More

'This technology enables people to 'see' radiation,' says Zhong He, professor of nuclear e...

Turn on any old science fiction film and odds are that you'll see someone listening to the ominous chirping of a Geiger counter. It's very dramatic, but not very precise and, unfortunately, nuclear scientists and engineers of today are stuck with the same problem. Now, researchers at the University of Michigan have developed a faster, cheaper way for nuclear power plants to detect and map dangerous hot spots and leaky fuel rods using a camera that maps radiation in real time.  Read More

The SaveOneLife system

Boot insoles can turn a pair of really uncomfortable brogues into podiatric clouds that can take a long hike and remove the foot ache. Now, Lemur Studio Design based in Bogota, Colombia, has come up with a concept for insoles that won’t just save your instep, but could save your life. A submission to the World Design Impact Prize 2013-2014 competition, SaveOneLife is a wearable mine detector that fits in a shoe and warns the wearer if and where a potentially deadly landmine might lurk nearby.  Read More

The spherical middle chamber of DarkSide-50 is filled with 7,000 gal of scintillator fluid

Like the Higgs Boson, dark matter is one of those things in the Universe that evidence points to, but is very difficult to pin down. A team of researchers is looking to verify the existence of this most elusive of ingredients that is thought to make up 23 percent of the Universe using powerful detectors buried deep in an Italian mountain.  Read More

Nest Labs' new Protect smoke and carbon monoxide alarm brings an Apple-like penchant for c...

Say you're a former Apple engineer and VP. Now say you leave the company, but you just can't shake your hankerin' to take clunky products, simplify them, and make them consumer-friendly. What do you do? Well, if you're Tony Fadell, then you found your own company that gives boring and complicated home sensors an Apple-like makeover. After finding success with its Nest thermostat, Fadell's Nest Labs is now expanding into the realm of smoke alarms.  Read More
