Researchers at the National Institute of Standards and Technology (NIST) spent 75 days on the job carrying out some very important homework–measurements in a "typical dwelling" of the release, distribution and fate of particles almost as tiny as the diameter of a single DNA molecule. Particles ranging in size from 100 nanometers down to 2.5 nanometers that were emitted by gas and electric stoves, hair dryers, power tools and candles were tracked and analyzed. Monitoring such tiny...

The ability to efficiently and unobtrusively screen for trace amounts of explosives on airline passengers could improve travel safety — without invoking the ire of inconvenienced fliers. Toward that end, mechanical engineer and fluid dynamicist Matthew Staymates of the National Institute of Standards and Technology in Gaithersburg, Maryland, and colleagues have developed a prototype air sampling system that can quickly blow particles off the surfaces of shoes and suck them away for...

Renewed and expanded A2LA accreditation doubles scope of services. Vernon Hills, IL (PRWEB) November 11, 2011 InnoCal Calibration and Repair Services announces another successful completion of accreditation in accordance with the recognized International Standard ISO/IEC 17025:2005 General Requirements for the Competence of Testing and Calibration Laboratories as determined by the American Association of Laboratory Accreditation (A2LA). In addition to having its A2LA accreditation extended...

Draft Roadmap For Cloud Computing Technology
2011-11-10 11:27:12

The National Institute of Standards and Technology (NIST) has released for public comment a draft "roadmap" that is designed to foster federal agencies' adoption of cloud computing, support the private sector, improve the information available to decision makers and facilitate the continued development of the cloud computing model. NIST plans to issue the final U.S. Government Cloud Computing Roadmap as a three-volume work. The first two volumes were posted for public comment on Nov. 1,...

Fish Flu: Genetics Approach May Lead To Treatment
2011-11-10 09:31:00

A research team at the National Institute of Standards and Technology (NIST) has provided the first look* at a genetic structure that may play a critical role in the reproduction of the infectious salmon anemia virus (ISAV), more commonly known as the "fish flu." A scourge in fish farms with a mortality rate as high as 90 percent, ISAV was recently found in wild salmon in the Pacific Northwest for the first time, threatening an already dwindling population and the vast food web it supports....

The National Initiative on Cybersecurity Education (NICE) has published for public comment a draft document that classifies the typical duties and skill requirements of cybersecurity workers. The document is meant to define professional requirements in cybersecurity, much as other professions, such as medicine and law, have done. NICE is an interagency effort coordinated by the National Institute of Standards and Technology (NIST) and focused on cybersecurity awareness, education, training...

Why there is stuff in the universe–more properly, why there is an imbalance between matter and antimatter–is one of the long-standing mysteries of cosmology. A team of researchers working at the National Institute of Standards and Technology (NIST) has just concluded a 10-year-long study of the fate of neutrons in an attempt to resolve the question, the most sensitive such measurement ever made. The universe, they concede, has managed to keep its secret for the time being, but...

Not to pick up electrons, but tweezers made of electrons. A recent paper by researchers from the National Institute of Standards and Technology (NIST) and the University of Virginia (UVA) demonstrates that the beams produced by modern electron microscopes can be used not just to look at nanoscale objects, but to move them around, position them and perhaps even assemble them. Essentially, they say, the tool is an electron version of the laser "optical tweezers" that have become a standard...

NIST's Compact Frequency Comb Could Go Places
2011-10-27 04:51:47

Laser frequency combs–extraordinarily precise tools for measuring frequencies (or colors) of light–have helped propel advances in timekeeping, trace gas detection and related physics research to new heights in the past decade. While typical lasers operate at only a single or handful of frequencies, laser frequency combs operate simultaneously at many frequencies, approaching a million for some combs. These combs have very fine, evenly spaced "teeth," each a specific frequency,...

An advanced material that could help bring about next-generation "spintronic" computers has revealed one of its fundamental secrets to a team of scientists from Argonne National Laboratory (ANL) and the National Institute of Standards and Technology (NIST). The material, constructed of two different compounds, might one day allow computers to use the magnetic spin of electrons, in addition to their charge, for computation. A host of innovations could result, including fast memory devices...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
