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)
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)
New sensor system improves detection of lead, heavy metals
The Department of Energy's Pacific Northwest National Laboratory has developed a new rapid, portable and inexpensive detection system that identifies personal exposures to toxic lead and other dangerous heavy metals. view more (2008-02-13)
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)
Mass flowering crops enhance pollinator densities at a landscape scale
The EU response to recent declines in pollinators and consequent loss of pollination services has been the inclusion of pollinator-friendly management in agri-environment schemes. These comprise the promotion of semi-natural habitats, such as set-aside and field margin strips. Yet, mass flowering crops, such as oilseed rape, are assumed to be of... view more... (2003-10-08)
Military imagery analysis assistant
Friend or enemy - what kind of tank or ship can be seen in aerial or satellite photo? The RecceMan identification assistant, which helps recognize the most diverse objects quickly and accurately, is the first interactive image recognition system produced for the German army. view more (2001-12-03)
Novel temperature calibration improves NIST microhotplate technology
Researchers at the National Institute of Standards and Technology (NIST) have developed a new calibration technique that will improve the reliability and stability of one of NIST's most versatile technologies, the microhotplate. view more (2009-08-12)
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)
Breast Feeding May Not Protect Against Obesity
Breast feeding does not protect against overweight and obesity, according to two studies in this week's BMJ. The first study followed 2,250 male Brazilians for 18 years, for whom detailed breast feeding information was collected in early childhood. The results were mostly negative. Duration of breast feeding showed no association with several... view more... (2003-10-15)
Ethnic background may be associated with diabetes risk
Fat and muscle mass, as potentially determined by a person's ethnic background, may contribute to diabetes risk, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). view more (2009-10-06)
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)
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)
Aid and health experts call for Government to support humanitarian capacity to respond to weapons of mass destruction
The London School of Hygiene and Tropical Medicine and Merlin, the charity that provides healthcare for people in crises, have completed a study of the potential humanitarian response to the use of weapons of mass destruction (WMD). In the detailed paper we call for the Government to support an independent group of NGOs to prepare for a response... view more... (2003-01-09)
Record-breaking tuning lasers lead to better data flow
A novel two-chip approach for fabricating tunable lasers using a micro-machined mirror membrane was developed by IST project TUNVIC. Such lasers allow the free selection of a wavelength out of a wide range that will ultimately lead to an increase in flexibility of future optical networks. view more (2004-03-11)
