A new draft computer security publication from the National Institute of Standards and Technology (NIST) provides guidance for vendors and security professionals as they work to protect personal computers as they start up. The first software that runs when a computer is turned on is the "Basic Input/Output System" (BIOS). This fundamental system software initializes the hardware before the operating system starts. Since it works at such a low level, before other security protections are in...

The National Institute of Standards and Technology (NIST) has issued the world's first reference material for single-wall carbon nanotube soot. Distantly related to the soot in your fireplace or in a candle flame, nanotube-laden soot is the primary industrial source of single-wall carbon nanotubes, perhaps the archetype of all nanoscale materials. The new NIST material offers companies and researchers a badly needed source of uniform and well-characterized carbon nanotube soot for material...

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a prototype device capable of absolute measurements of optical power delivered through an optical fiber. The device is the world's first fiber-coupled cryogenic radiometer that links optical fiber power measurements directly to fundamental electrical units and national standards. It uses a microscopic forest of carbon nanotubes–the world's darkest material–to measure values that are about...

An advance in sensor design* by researchers at the National Institute of Standards and Technology (NIST) and the University of Waterloo's Institute of Quantum Computing (IQC) could unshackle a powerful, yet high-maintenance technique for exploring materials. The achievement could expand the technique–called neutron interferometry–from a test of quantum mechanics to a tool for industry as well. Neutron beams can be used in dozens of ways to probe complex molecules and other...

Physicists at the National Institute of Standards and Technology (NIST) have found a way to manipulate atoms' internal states with lasers that dramatically influences their interactions in specific ways. Such light-tweaked atoms can be used as proxies to study important phenomena that would be difficult or impossible to study in other contexts. Their most recent work, appearing in Science,* demonstrates a new class of interactions thought to be important to the physics of superconductors that...

In fire experiments conducted in uniformly furnished, but vacant Chicago-area townhouses, National Institute of Standards and Technology (NIST) researchers uncovered temperature and heat-flow conditions that can seriously damage facepiece lenses on standard firefighter breathing equipment, a potential contributing factor for first-responder fatalities and injuries. The findings are detailed in a report* from a research study sponsored by the U.S. Fire Administration and Department of...

The National Institute of Standards and Technology (NIST) published a revised biometric standard in November, 2011, that vastly expands the type and amount of information that forensic scientists can share across their international networks to identify victims or solve crimes. Biometric data is a digital or analog representation of physical attributes that can be used to uniquely identify us. The new standard is the Data Format for the Interchange of Fingerprint, Facial & Other...

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...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
