Teaming up with investigators from the State Office of Criminal Investigation in Berlin, Fraunhofer researchers have come up with an automated assistance system for image and video evaluation that can detect child-pornographic images from among even large volumes of data. Soon, it will make prosecutors℠ work easier. Investigators estimate that there are currently more than 15 million photographs of child abuse victims circulating on the Internet. By the time this material has been...

New research using graphene presents the most precise measurements of the quantum Hall effect ever made, 1 of the key steps in the process to redefine 2 SI units Groundbreaking research by the National Physical Laboratory's (NPL) Quantum Detection Group and an international team of collaborators is underpinning the biggest change in the Système Internationale d'unités (SI Units) since the system began 50 years ago. It has long been the goal of scientists to...

Diamonds may be best known as a symbol of long-lasting love. But semiconductor makers are also hoping they'll pan out as key components of long-lasting micromachines if a new method developed at the National Institute of Standards and Technology (NIST) for carving these tough, capable crystals proves its worth. The method offers a precise way to engineer microscopic cuts in a diamond surface, yielding potential benefits in both measurement and technological fields. By combining their own...

The electromagnetic force has gotten a little stronger, gravity a little weaker, and the size of the smallest "quantum" of energy is now known a little better. The National Institute of Standards and Technology (NIST) has posted the latest internationally recommended values of the fundamental constants of nature. The constants, which range from relatively famous (the speed of light) to the fairly obscure (Wien frequency displacement law constant) are adjusted every four years in response to...

National Institute of Standards and Technology (NIST) researchers are working to reduce the uncertainty associated with climate-change measurements using a mobile temperature-sensing technology made for tracking delicate or perishable, high-value packages in transit. Developed by international shipper FedEx and tested with help from NIST, the device connects to cell phone networks to provide users with near real-time information on the package's precise location, temperature, humidity,...

In a step toward taking the most advanced atomic clocks on the road, physicists at the National Institute of Standards and Technology (NIST) have designed and demonstrated a super-stable laser operating in a cramped, vibrating location"”a minivan. The experiment shows how advanced lasers can be made both stable and transportable enough for field use in geodesy, hydrology, improved radar and space-based tests of fundamental physics. The drive tests, limited to a short excursion of five...

A reliable and trustworthy system of weights and measures is vital for economic activity. Maintaining that system requires constant vigilance, and that's where the National Institute of Standards and Technology (NIST) Weights and Measures Division (WMD) comes in. While the division routinely hosts meetings and online classes to help state regulators enforce compliance, NIST is now making an effort to reach out to industry and retailers so that they can proactively identify and address...
