The SmartMat is a Wi-Fi enabled device designed to fit under a regular doormat

We've got smart doorbells, smart locks and smart door handles, so why not a smart doormat? Dr. Andrew Clark has created just such a device called, surprisingly enough, the SmartMat. Designed to be placed under a regular doormat, the SmartMat acts as a pressure sensor and features Wi-Fi connectivity to allow actions to be triggered when someone steps on it.  Read More

In testing the fluorescent compound, the team observed a difference in the intensity of th...

Central to the dangers of so-called "date-rape" drugs is the fact that they are difficult to detect. Indeed, GHB, one of the most commonly-used of such drugs, is both colorless and odorless. A team of researchers from the National University of Singapore (NUS) has developed a fluorescent sensor which, when mixed with a drink containing GHB, changes color within 30 seconds, potentially alerting people soon after their drink has been tampered with.  Read More

By infusing the leaves of an Arabidopsis thaliana plant with nanoparticles, MIT researcher...

In 2010, Stanford University researchers reported harnessing energy directly from chloroplasts, the cellular "power plants" within plants where photosynthesis takes place. Now, by embedding different types of carbon nanotubes into these chloroplasts, a team at MIT has boosted plants' ability to capture light energy. As well as opening up the possibility of creating "bionic plants" with enhanced energy production, the same approach could be used to create plants with environmental monitoring capabilities.  Read More

Artist's conception of a quantum atomic gas undergoing laser cooling in an ultracold refri...

Quantum physics likes the cold. In particular, macroscopic quantum phenomena such as superconductivity, superfluidity, and Bose-Einstein condensates (BECs) are only found at quite low temperatures. While current refrigeration methods can attain temperatures of a few nanoKelvins, attaining still lower temperatures is largely prevented by the need to support the cooling matter against the pull of Earth's gravity. Now NASA's Cold Atom Lab, scheduled for installation on the ISS in 2016, will aim for temperatures roughly four orders of magnitude smaller.  Read More

The QuadStick aims to afford quadriplegics the ability to play video games

A new device called QuadStick is designed to give quadriplegics the ability to play video games without the need for a traditional gaming controller. Instead, it uses a series of sip and puff sensors, a lip position sensor, a push switch, and voice commands to represent the inputs of a standard video game controller.  Read More

In October of last year, the Canadian Avalanche Centre (CAC) issued a warning about the dangers of relying on smartphone apps that were being marketed as economical alternatives to avalanche transceivers. But a new smartphone app and add-on hardware component could provide an alternative that is not only cheaper than dedicated avalanche transceivers, but also provides additional functionality.  Read More

The True Love Tester bra automatically unhooks itself when it senses the woman feeling tru...

In one of the more absurd examples of wearable technology we've seen lately, a Japanese firm has created a high-tech bra called the True Love Tester that literally snaps open only when it senses that the woman is in love.  Read More

The optical sensor system developed to detect the amount of salt on a road (Photo: UC3M)

Just as a good meal can be ruined by too much table salt, too much sodium chloride applied to road surfaces to prevent icing can have a detrimental effect on vehicles, infrastructure and the environment. Engineers at Spain's Carlos III University (UC3M) have developed an optical sensor intended to prevent excessive salt treatment by detecting the amount of salt already on the road in real time.  Read More

Scientists at Berkeley Lab and the University of California (UC) Berkeley have created sensitive, tactile sensors that are similar to a cat's whiskers. The so-called "e-whiskers" could be used to help robots feel their way around a space.  Read More

Crystal structure of sodium bismuthide (Na3Bi), one of the newly discovered 3D topological...

Exciting times are ahead in the high-tech industries with the discovery by three independent groups that a new class of materials mimic the special electronic properties of graphene in 3D. Research into these superfast massless charge carriers opens up a wide range of potential applications in electronics, including smaller hard drives with more storage capacity, faster transistors and more efficient optical sensors.  Read More
