Thanks to their habit of remaining concealed, the first indication people get that termites have invaded their home is after they’ve already wreaked their particular brand of wood-eating havoc. According to Associate Professor Adam Osseiran of Western Australia’s Edith Cowan University, the yearly damage bill in the U.S. for termite damage tops US$12 billion, while in Australia they cause an estimated $1 to $3 billion damage each year. In attempt to reduce such damage, Osseiran and his team have developed an acoustic sensor that is so sensitive it can detect termite infestation by “hearing” them chew through timber. Read More

Who hasn't killed at least one houseplant in their time? Personally, I have given up trying to nurture these fussy organisms altogether and my house is now a green-free zone. Technology like the Koubachi Wi-Fi Plant Sensor might entice me to consider trying to bring the outdoors in once more though - it's designed to take all the hard work out of keeping plants alive while they reside in the unnatural environment that are our homes.

Researchers at the University of Exeter have created a transgenic zebrafish which produces highly targeted green fluorescent signals when exposed to environmental estrogens. Read More

A duck pond may seem like the ideal place to spend a peaceful spring afternoon, but during mating season it can look like the scene of a gang attack. Though ducks as a species are famously monogamous, unattached drakes can be extremely aggressive. They attack any female in sight in a mating frenzy that often ends in the injury or death of the victim. This has resulted in the ducks developing ways to prevent unwanted matings and the drakes ways to overcome their defenses. Researchers in North America are developing a novel way to study this "evolutionary arms race" that uses high-speed cameras, force transducers and model duck oviducts made of glass. Read More
According to the U.S. Department of Justice, around 200,000 women were raped in the U.S. in 2007 with the aid of a “date rape” drug – and because so many cases go unreported, the actual figure is believed to be 80 to 100 percent higher. GHB is one of the most commonly used drugs because it is odorless, tasteless and invisible when dissolved in water. Now researchers at Tel Aviv University’s Sackler Faculty of Exact Sciences have developed an easy-to-use sensor that, when dipped into a cocktail, can instantly detect GHB and another commonly used date rape drug, ketamine.

Bridging the gap between computer generated music and real-world instruments, the "Imaginary Marching Band" is a fledgling, open-source project that allows music to be created by imitating the actions of playing the real thing on a sensor-equipped glove. The work of Scott Peterman, a Masters student at Parsons New School Of Design in New York City, the prototype system uses MIDI data output from the gloves via USB to reproduce the full range of notes from instruments such as the trumpet and trombone.

Of all the things we expected to see on display at CES in Las Vegas, a garbage can was not one of them. Nonetheless, amongst the tablet computers, 3D camcorders and iPhone apps, there sat the simplehuman sensor can. Like some other “touchless” garbage cans, its built-in sensor detects when someone is nearby, causing the can to obligingly open its lid. What makes it special – perhaps – is the company’s claim that the can’s “multi-sense” technology can adapt to what the user is doing. Read More
Wearable health monitors have been available for some time, providing feedback on functions such as heart rate and blood pressure. They represent the tip of a potentially huge health and fitness market, from athletes and emergency services personnel to patients both in and recently discharged from hospital, who could benefit from real-time, intelligent wireless body monitoring of vital signs. Telemetry technology provider Toumaz has developed an ultra-low power system to wirelessly monitor heart rate, ECG, temperature and physical activity. The Sensium Life Platform has just been used to monitor the health of team members during a record-breaking 4,000 kilometer transantarctic expedition that not only made the fastest vehicle crossing of the Antarctic, but was also the first expedition to use biofuels extensively in Antarctica, and featured the first bio-fuelled vehicle ever to reach the South Pole.

The recent Yemeni bomb threat has only highlighted the need for quick, accurate ways of detecting explosives. With their excellent sense of smell and the ability to discern individual scents, even when they’re combined or masked by other odors, this task is usually given to man’s best friend. But training these animals can be expensive and good sniffer dogs can be hard to find. Scientists have now developed an electronic sensor they say is more sensitive and more reliable at detecting explosives than any sniffer dog. Read More
People living in landslide-prone areas will be glad to know that a new technology has been developed which monitors soil acoustics to determine when a landslide is imminent. The system consists of a network of sensors, buried across a hillside considered a risk. As soil moves within the hillside, it creates noise – the more the amount of movement, the louder the noise. When that noise reaches a threshold level, the system sends a text message warning to local authorities, that a landslide is about to occur. Read More
