Second Draft Of Federal ID Credential Security Standard Released By NIST
2012-07-12 17:27:50

The National Institute of Standards and Technology (NIST) has released the second-round draft version of its updated security standard for identity credentials in the Personal Identity Verification cards (PIV cards) that all federal employees and contractors must use. NIST is requesting comments from the public on the document, which is intended to be the last draft before the final version is published. The document is the next step toward updating Federal Information Processing Standard...

Improvements in Fire Department Tactics Using Live Fire Tests with FDNY
2012-07-12 11:06:54

In the name of science, but with aim of saving lives, preventing injuries and reducing property losses, members of the New York City Fire Department (FDNY) spent much of the first two weeks in July setting fire to 20 abandoned townhouses on Governors Island, about a kilometer from the southern tip of Manhattan. In a series of "live burn" experiments, conducted in collaboration with the National Institute of Standards and Technology (NIST) and Underwriters Laboratories (UL), New York...

Next-generation "smart" electrical meters for residential and commercial buildings will have computerized operating systems just as laptops or mobile devices do. On July 10, 2012, the National Institute of Standards and Technology (NIST) published its first-ever draft guidelines to help utility companies test their procedures for upgrading meters securely from a remote location. The draft publication offers a generic set of testing criteria to help any utility determine whether its method...

The National Institute of Standards and Technology (NIST) has released a proposed update to its guidelines for securing mobile devices–such as smart phones and tablets–that are used by the federal government. NIST is asking for public comment on the draft document. Mobile devices allow workers, including government employees, to work in multiple locations and to improve their efficiency. But the same features that make these devices desirable make them a security challenge....

The National Institute of Standards and Technology (NIST) has released a guide to help improve the design of electronic health records for pediatric patients so that the design focus is on the users–the doctors, nurses and other clinicians who treat children. While hospitals and medical practices are accelerating their adoption of electronic health records, these records systems often are not ideal for supporting children's health care needs. Young patients' physiology is different...

Stripping Gold From AFM Probes Allows Better Measurement Of Picoscale Forces
2012-06-28 12:02:30

Gold is not necessarily precious–at least not as a coating on atomic force microscope (AFM) probes. JILA researchers found that removing an AFM probe's gold coating–until now considered helpful–greatly improved force measurements performed in a liquid, the medium favored for biophysical studies such as stretching DNA or unfolding proteins. As described in Nano Letters,* stripping the gold from the diving-board-shaped probe, or cantilever, with a brief chemical bath...

NIST Measures Up For The Olympics
2012-06-28 11:56:56

In yet another Olympian feat of measurement, researchers at the National Institute of Standards and Technology (NIST) recently calibrated a tape that will be used to measure out the distance of this summer's Olympic marathon–a distance of 26 miles 385 yards–to 1 part in 1,000. Measurement is a vital aspect of the Olympic Games. Officials measure the height of jumps, the speed of races, and the mass of weights to determine who wins a medal and who goes home. The marathon is no...

First Heralded Single Photon Source Made From Silicon Demonstrated
2012-06-28 10:53:14

In an important step towards more practical quantum information processing, researchers from the National Institute of Standards and Technology (NIST), the University of California, San Diego; and the Politecnico di Milano in Milan, Italy, have demonstrated the first heralded single photon source made from silicon. This source complements two other recently developed silicon-based technologies–interferometers for manipulating the entanglement of photons and single photon...

Clay-based Coating May Show The Way To New Generation Of Green Flame Retardants
2012-06-28 10:46:09

In searching for better flame retardants for home furnishings–a large source of fuel in house fires–National Institute of Standards and Technology (NIST) researchers defied the conventional wisdom and literally hit a wall, one made of clay. It wasn't a dead end, but rather a surprising result that may lead to a new generation of nonhalogenated, sustainable flame retardant technology for polyurethane foam. The thick, fast-forming coating that the NIST team created has a...

Word of the Day
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
