Researchers at Commerce’s National Institute of Standards and Technology (NIST) designed an instrument that quickly and precisely sniffs trace amounts of chemical compounds that indicate poultry spoilage without damaging the product itself. The process can detect minute amounts of spoilage compounds and can be used by suppliers during all stages of processing, transport and storage. Several proactive measures are used in the United States to keep poultry from going bad between the time it leaves the farm to when it reaches the grocery cart. (More)

Fully incorporating modern information technology into the healthcare system promises many benefits, including better quality care, less paperwork and fewer medical errors while reducing unnecessary costs. In any such critical application, however, it’s important to ensure that the new technology behaves as expected. To meet this need in health information technology, a broad array of public and private stakeholders have been working with Commerce’s National Institute of Standards and Technology (NIST). NIST has released the first of four installments of a new health IT test method and related software. (More)

Commerce’s National Institute of Standards and Technology (NIST) has issued an initial list of standards, a preliminary cyber security strategy, and other elements of a framework to support transforming the nation’s aging electric power system into an interoperable “Smart Grid,” a key component of the Obama administration’s energy plan and its strategy for American innovation. By integrating digital computing and communication technologies and services with the power-delivery infrastructure, the Smart Grid will enable bidirectional flows of energy and two-way communication and control capabilities.

Commerce’s National Institute of Standards and Technology (NIST) and National Telecommunications and Information Administration (NTIA) have announced plans to create a demonstration broadband communications network for the nation’s emergency services agencies using a portion of the radiofrequency spectrum freed up by the recent transition of U.S. broadcast television from analog to digital technologies. This demonstration network is currently in the preliminary planning stages and is expected to go live in mid-2010. (More)

Viewers of TV dramas don’t focus on the technology behind how a forensics crime team tracks a terrorist or drug ring using cell phone data, but scientists at the National Institute of Standards and Technology (NIST) do. NIST researchers have developed a new technique aimed at improving the validation of a crime lab’s cell phone forensics tools. Early experiments show promise for easier, faster and more rigorous assessments than with existing methods. (More) (Report-PDF)

Human red blood cells, in which membrane proteins are targeted and labeled with quantum dots, reveal the clustering behavior of the proteins. The number of purple features, which indicate the nuclei of malaria parasites, increases as malaria development progresses. The NIST logo at bottom was made by a photo lithography technique on a thin film of quantum dots, taking advantage of the property that clustered dots exhibit increased photoluminescence.

A joint research team, working at Commerce’s National Institute of Standards and Technology (NIST) and the National Institute of Allergy and Infectious Diseases (NIAID), has discovered a method of using nanoparticles to illuminate the cellular interior to reveal these slow processes. Nanoparticles, thousands of times smaller than a cell, have a variety of applications. One type of nanoparticle called a quantum dot glows when exposed to light. These semiconductor particles can be coated with organic materials, which are tailored to be attracted to specific proteins within the part of a cell a scientist wishes to examine. (More)

The eyes may be the mirror to the soul, but the iris reveals a person’s true identity—its intricate structure constitutes a powerful biometric. A new report by computer scientists at Commerce’s National Institute of Standards and Technology (NIST) demonstrates that iris recognition algorithms can maintain their accuracy and interoperability with compact images, affirming their potential for large-scale identity management applications such as the federal Personal Identity Verification program, cyber security and counterterrorism.

In the aftermath of the Sichuan earthquake that occurred in China this past year and its high number of casualties, the U.S. and China have signed a protocol for cooperation on earthquake and volcano sciences. The protocol was signed by the U.S. Geological Survey, the National Science Foundation and Commerce’s National Institute of Standards and Technology (NIST) in the U.S., and the Chinese Earthquake Administration and the National Natural Science Foundation of the People’s Republic of China. Shown are NIST Deputy Director Patrick Gallagher and Yin Chaomin, vice administrator of the Chinese Earthquake Administration. (More) (Protocol)
