No more loose screws!
Machine parts and tools with a functional coating made of diamond-like carbon are not only more wear-resistant than usual ones, but also smarter. At the Hanover Fair, visitors can see ”intelligent“ washers and tools that measure whether screws are sufficiently tight. ---------- Modern wind turbines are exposed to a considerable air... view more...

Silicon And Diamond
To make super-durable and strong details it is necessary to use so-called diamond composites, i.e. materials (matrixes) with incorporated tiny diamonds. The matrix is to be durable, strong, wear-proof as well as monolithic by structure ensuring chemical interaction with diamonds. To avoid internal tension this matrix must have physical... view more... (2002-09-23)
Liquid crystal multilayer study promises improvements in manufacturing techniques for LCD's
In order to successfully fabricate a commercial Liquid Crystal Display, uniform orientation of the liquid crystal (LC) molecules is required. view more (2005-10-12)
Normalizing tumor vessels to improve cancer therapy
Chemotherapy drugs often never reach the tumors they're intended to treat, and radiation therapy is not always effective, because the blood vessels feeding the tumors are abnormal-"leaky and twisty" in the words of the late Judah Folkman, MD, founder of the Vascular Biology program at Children's Hospital Boston. view more (2008-08-26)
Racial Tension in a "Split-Second"
Interracial and interethnic interactions can often be awkward and stressful for members of both majority and minority groups. People bring certain expectations to their interactions with members of different groups-they often expect that these interactions will be awkward and less successful in establishing positive, long-lasting relationships... view more...

Link between migranes and sleep disorders in children
Children with a migraine headache are more likely to have sleep disorders, such as obstructive sleep apnea (OSA) and lack of sleep, than children without a migraine. view more (2008-06-10)
Getting on 'the GABA receptor shuttle' to treat anxiety disorders
There are increasingly precise molecular insights into ways that stress exposure leads to fear and through which fear extinction resolves these fear states. view more (2009-10-22)
SMART-1 uses new imaging technique in lunar orbit
ESA's SMART-1 spacecraft has been surveying the Moon's surface in visible and near-infrared light using a new technique, never before tried in lunar orbit. view more (2005-12-27)
NC State Engineers Discover Nanoparticles Can Break On Through
In a finding that could speed the use of sensors or barcodes at the nanoscale, North Carolina State University engineers have shown that certain types of tiny organic particles, when heated to the proper temperature, bob to the surface of a layer of a thin polymer film and then can reversibly recede below the surface when heated a second time. view more (2008-09-17)
A cushion of air trapped under the rice fields of Senegal
Rice cultivation uses great volumes of water, especially where the submerged-field method involving surge flooding irrigation is practised. Maintenance of a layer of water on the soil surface throughout the cropping period usually favours its infiltration deeper down. However, it has been known for many years that in some regions water often does... view more... (2004-04-15)
Light turns liquid
LIGHT can be turned into a glowing stream of liquid that splits into droplets and splatters off surfaces just like water. The researchers who`ve worked out how to do this say "liquid light" would be the ideal lifeblood for optical computing, where chips send light around optical "circuits" to process data. Liquid light sounds like a... view more... (2002-07-03)
NEW APPROACH TO STICKY PROBLEM
"Over the past 20 years people have been trying to develop techniques for studying structures of polymer surfaces to understand how these determine their adhesive performance," says Dr Leggett of the Manchester research team. "However, such surfaces are extremely difficult to study directly. They degrade very quickly under beams of... view more... (1999-11-04)
Mars under the spotlight again
Relieved UK scientists are celebrating the news that NASA's Mars Reconnaissance Orbiter (MRO) appears to have smoothly entered Mars orbit on Friday night (March 10th). view more (2006-03-14)
Melting defects could lead to smaller, more powerful microchips
As microchips shrink, even tiny defects in the lines, dots and other shapes etched on them become major barriers to performance. Princeton engineers have now found a way to literally melt away such defects, using a process that could dramatically improve chip quality without increasing fabrication cost. view more (2008-05-05)
UCLA physicists report advance toward nanotechy approach to protein engineering
UCLA physicists report a significant step toward a new approach to protein engineering in the June 8 online edition, and in the July print issue, of the Journal of the American Chemical Society. view more (2006-06-12)
Latex means environmentally friendly packaging
For several years, Caisa Andersoon has been trying to create a better barrier against moisture and oxygen in our food packaging. On December 20, she will submit her doctoral dissertation at Karlstad University in Sweden. Latex has long been used for various types of surface treatment of paper. In recent years, interest has been focused on the... view more... (2002-12-17)
Mars Express has the sophisticated science to find the water ice on Mars
"The presence of such a large amount of water ice under Mars`s surface is very surprising. Especially so close to the surface!" says Gerhard Schwehm, Head of the Planetary Missions Division at ESA. The team working on ESA`s Mars Express, the next mission to the Red Planet, is thrilled by NASA`s Mars Odyssey detection of hydrogen-rich layers under... view more... (2002-05-30)
Falls from bouncy chairs or car seats significant cause of injury in babies
Falls from bouncy chairs or car seats are a significant cause of injury in very young children, finds research in Archives of Disease in Childhood. view more (2002-02-18)
Sources of energy for the EFDA-JET nuclear fusion experimental reactor
JEMA, the company based in Lasarte in the Basque Country, has recently put into operation the two energy supply plants designed and manufactured for the European EFDA (the European Fusion Development Agreement)-JET nuclear fusion experimental reactor at Culham in the United Kingdom. This reactor is one of the plants on which ITER, the largest... view more... (2004-02-19)
Men and women recover differently after surgery
Women emerge more quickly than men from general anaesthesia, but have a slower return to former health after surgery, according to a study in this week's BMJ. Researchers at Alfred Hospital in Australia studied 241 men and 222 women for three days after undergoing surgery to identify differences in the quality of recovery between the sexes. They... view more... (2001-03-21)
