Metrology News Stories
Current Metrology News Events, Discoveries and Articles
Scientists set out to measure how we perceive naturalness
Natural products are highly valued by consumers yet their properties have been difficult to reproduce fully in synthetic materials, placing a drain on our limited natural resources. Until now ... (2008-07-07)
NIST's Novel 'Noise Thermometry' May Help Redefine International Unit of Temperature
After seven years of work, researchers at the National Institute of Standards and Technology (NIST) have built a system that relies on the "noise" of jiggling electrons as a basis for measuring temperatures with extreme precision. (2008-06-04)
Bon MOT: Innovative atom trap catches highly magnetic atoms
A research team from the National Institute of Standards and Technology (NIST) and the University of Maryland has succeeded in cooling atoms of a rare-earth element, erbium, to within two millionths of a degree of absolute zero using a novel trapping and laser cooling technique. (2008-04-03)
Silicon chips for optical quantum technologies
A team of physicists and engineers has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards the long sought after goal of a super-powerful quantum computer. (2008-03-28)
Physicists team up to learn how quantum mechanical states break down
Researchers at the US Department of Energy's Ames Laboratory, the University of California, Santa Barbara, and Microsoft Station Q have made significant advancements in understanding a fundamental problem of quantum mechanics -- one that is blocking efforts to develop practical quantum computers with processing speeds far superior to conventional computers. Their respective theoretical and experimental studies investigate how microscopic objects lose their quantum-mechanical properties through interactions with the environment. (2008-03-24)
Sandia weighs in on new definition for kilogram
The kilogram is losing weight and many international scientists, including some at Sandia National Laboratories, agree that it's time to redefine it. (2008-02-29)
International effort takes critical steps to accelerate growth of global biofuels market
The governments of the United States, Brazil and the European Union (EU)-the world's major producers of biofuels-today released an analysis of current biofuel specifications with the goal of facilitating expanded trade of these renewable energy sources. (2008-02-04)
New quantum dot transistor counts individual photons
A transistor containing quantum dots that can count individual photons (the smallest particles of light) has been designed and demonstrated at the National Institute of Standards and Technology (NIST). (2007-10-12)
Nuclear medicine now safer than ever
Hospitals are now able to ensure that the correct dose is administered to the 670,000 patients that undergo nuclear medicine procedures every year due to a new device developed by scientists at the National Physical Laboratory (NPL). (2007-10-11)
The day LISA Pathfinder hung in the balance
At the core of ESA's LISA Pathfinder mission sit two small hearts. Each is a cube, just 5 centimetres across. Together they will allow LISA Pathfinder to lay the foundations for future space-based measurements that investigate the very core of Einstein's General Relativity. (2006-10-12)
