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...

Humans spend greater than 90 percent of their time indoors, but we're never alone there. Bacteria and viruses, scientists estimate, make up half of the world's biomass–some 10 nonillion (1 followed by 31 zeros) microorganisms–and we most often meet them within enclosed spaces. So, that's where the modern microbe hunter often looks first. A new report issued by the National Institute of Standards and Technology (NIST) offers guidance to make the hunting more effective. A...

The National Institute of Standards and Technology (NIST) has released a new standard reference material (SRM) to aid in the detection of two explosive compounds that are known to be used by terrorists. Researchers designed the new test samples to simulate the size and behavior of residues that remain after handling the explosives PETN (pentaerythritol tetranitrate) and TATP (triacetone triperoxide). Instrument developers, academic researchers and government labs can use the SRM to test,...

Successful test at PTB of optical magnetometer with potential applications in brain imaging for neurological diagnostics and in basic research. In future a new magnetic sensor the size of a sugar cube might simplify the measurement of brain activity. In the magnetically shielded room of Physikalisch-Technische Bundesanstalt (PTB) the sensor has passed an important technical test: Spontaneous as well as stimulated magnetic fields of the brain were detected. This demonstrates the potential...

Researchers at the National Institute of Standards and Technology (NIST) have developed a prototype bioreactor–a device for culturing cells to create engineered tissues–that both stimulates and evaluates tissue as it grows, mimicking natural processes while eliminating the need to stop periodically to cut up samples for analysis. Tissue created this way might someday be used to replace, for example, damaged or diseased cartilage in the knee and hip. Conventional methods for...

A new study by a team including scientists from the National Institute of Standards and Technology (NIST) indicates that thin polymer films can have different properties depending on the method by which they are made. The results suggest that deeper work is necessary to explore the best way of creating these films, which are used in applications ranging from high-tech mirrors to computer memory devices. Thin films spread atop a surface have many applications in industry. Inexpensive...

Researchers at the National Institute of Standards and Technology (NIST) have developed a novel way of producing light pulses that are "superluminal"–in some sense they travel faster than the speed of light. The technique, called four-wave mixing, reshapes parts of light pulses and advances them ahead of where they would have been had they been left to travel unaltered through a vacuum. The new method could be used to improve the timing of communications signals and to investigate the...

Researchers at the National Institute of Standards and Technology (NIST) have developed and published a new protocol for communicating with biometric sensors over wired and wireless networks–using some of the same technologies that underpin the web. The new protocol, called WS-Biometric Devices (WS-BD), allows desktops, laptops, tablets and smartphones to access sensors that capture biometric data such as fingerprints, iris images and face images using web services. Web services...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
