OSGi Communication Platform now in Automation
OSGi solutions (Open Gateway Services Initiative) are known as intelligent gateways within the areas of telecommunication, home networking and the automotive industry. Fraunhofer Institute for Integrated Circuits IIS now offers this standardized platform technology for control tasks in the field of automation technology. view more (2004-03-05)
Envisat`s MERIS captures image of Hurricane Elida
The Medium Resolution Imaging Spectrometer (MERIS) onboard ESA`s Envisat environmental satellite captured this dramatic image of Hurricane Elida off the west coast of Mexico on 25 July 2002. view more (2002-07-30)
UC San Diego Scientists Develop Sensor for Homemade Bombs
A team of chemists and physicists at the University of California, San Diego has developed a tiny, inexpensive sensor chip capable of detecting trace amounts of hydrogen peroxide, a chemical used in the most common form of homemade explosives. view more (2008-03-19)
Researchers catch ion channels in their opening act
Each thought or action sends a million electrical signals pulsing through your body. At the heart of the process of generating these electrical impulses is the ion channel. view more (2008-07-11)
Mutation protects from HIV - and increases risk of hepatitis C
More than 40 million people worldwide are infected with the human immunodeficiency virus HIV. In Africa alone this incurable immune deficiency caused more than two million deaths last year. Yet some people are resistant to infection: the reason for this is a mutation in their DNA which prevents the HIV virus from invading certain immune cells and... view more... (2002-07-17)
Fiber-based nanotechnology in clothing could harvest energy from physical movement
Nanotechnology researchers are developing the perfect complement to the power tie: a "power shirt" able to generate electricity to power small electronic devices for soldiers in the field, hikers and others whose physical motion could be harnessed and converted to electrical energy. view more (2008-02-14)
The Sensitive Side of Carbon Nanotubes: Creating Powerful Pressure Sensors
Blocks of carbon nanotubes can be used to create effective and powerful pressure sensors, according to a new study by researchers at Rensselaer Polytechnic Institute. view more (2007-10-24)
Fishy sixth sense could help robots navigate the oceans
Taking their cue from fish, scientists in the US have built a navigational aid that will help robots and remote sensors find their way around the world`s vast oceans. The team describes its research today in the Institute of Physics publication Journal of Micromechanics and Microengineering. Fish and many amphibian animals find their way through... view more...

Making robotic movement of goods more 'pallet-able'
Robots running amok and destroying property may be a staple in science fiction films, but they aren't welcome in factories, warehouses and other places where automatic guided vehicle (AGV) forklifts are used. view more (2006-11-13)
Safe decay detector developed by dentists and textile experts
Tooth decay could soon be detected without resorting to potentially harmful X-rays - by using a novel electrical technique developed by dental researchers at the University of Dundee in an unusual partnership with textile experts at Heriot Watt University. Laboratory tests show the device, which measures the electrical resistance of teeth, is... view more... (2002-03-20)
Glass sensors measure weathering effects
The corrosiveness of a specific atmosphere can be established in a few weeks by thin slices of special glass. The sensors are capable of monitoring the outdoor environment as well as indoors, for instance in sensitive production processes such as chip fabrication. view more (2004-10-04)
New biosensor could save lives by giving faster medical analysis.
Every day accident and emergency units have to treat patients who have taken some sort of drug overdose. To give treatment doctors need to know what the patient has taken. The circumstances can make often this difficult to ascertain quickly. Researchers are developing a new kind of biosensor, which can determine in minutes if a patient's blood... view more...

Electronic nose sniffs out toxins
Imagine a polka-dotted postage stamp-sized sensor that can sniff out some known poisonous gases and toxins and show the results simply by changing colors. view more (2009-09-14)
Iowa State engineer develops technology to quickly find leaks in spacecraft
Tiny meteors flash through space. There's spacecraft debris flying around, too. And so there's a risk that objects just a few millimeters across could pierce the thin aluminum skin of spacecraft such as the International Space Station orbiting 220 miles above Earth. view more (2007-10-03)
NIST micro sensor and micro fridge make cool pair
Researchers at the National Institute of Standards and Technology (NIST) have combined two tiny but powerful NIST inventions on a single microchip, a cryogenic sensor and a microrefrigerator. The combination offers the possibility of cheaper, simpler and faster precision analysis of materials such as semiconductors and stardust. view more (2008-04-16)
A sophisticated virtual simulation tool to test-drive new cars
The rapidly increasing demands of today's car buyers have placed a heavy burden on car manufacturers to constantly innovate. Building prototypes to test innovative car designs is a lengthy, not to mention expensive, process and one that companies keen to retain their competitive edge can ill afford. With contemporary simulation systems often... view more... (2003-09-09)
Measuring the health of the sea
Last summer Donostia City Council in the Basque Country installed a special buoy in the city's Concha Bay for the first time. The apparatus carried out analyses of the water quality in order to verify its suitability for bathing. This buoy was anchored at the bottom of the sea, halfway between the Santa Clara islet and the Concha and Ondarreta... view more... (2003-07-28)
Chemists measure copper levels in zinc oxide nanowires
Chemists at the National Institute of Standards and Technology (NIST) have been the first to measure significant amounts of copper incorporated into zinc oxide (ZnO) nanowires during fabrication. view more (2008-02-20)
