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...

NASA and the National Institutes of Standards and Technology (NIST) are sponsoring the second in a series of regional public workshops to gather ideas and suggestions on the design of the proposed National Network for Manufacturing Innovation (NNMI). The workshop will be held July 9 at the Cuyahoga Community College in Cleveland. "Designing for Impact II: Workshop on Building the NNMI" is a partnership between the interagency Advanced Manufacturing National Program Office in Gaithersburg,...

Laser Frequency Comb Helps Evaluate Novel Biomedical Decontamination Method
2012-06-14 12:20:07

Like many new measurement tools, the laser frequency comb seemed at first a curiosity but has found more practical uses than originally imagined. The technique for making extraordinarily precise measurements of frequency has now moved beyond physics and optics to advance biomedicine by helping researchers evaluate a novel instrument that kills harmful bacteria without the use of liquid chemicals or high temperatures. Generated by ultrafast lasers, frequency combs precisely measure...

Word of the Day
  • Good cheer; viands.
  • To revel; to feast.
The word 'bellycheer' may come from 'belle cheer', "good cheer".
