While bomb-sniffing dogs provide an invaluable service, training them using actual explosives can be risky for both the canines and their handlers. A new process could help, utilizing a harmless polymer that quickly absorbs the scent of explosives.
-
Some advanced electronic devices only function at extremely cold temperatures. Now engineers at NIST have developed a tiny cryogenic thermometer that uses a new mechanism to keep an eye on these sensitive instruments without taking up much room.

A new flow visualization study from the National Institute of Standards and Technology (NIST) starkly demonstrates why face masks with exhalation valves are not effective for slowing the spread of COVID-19.

Scientists have so far been unable to detect dark matter. But a new detector design, using an array of billions of tiny pendulums, could finally break the silence by searching for the effects of dark matter’s incredibly strong gravitational pull.

Although we may think of 3D-printed items as being hard, they're actually often made from soft gels, as is the case with bioprinted body parts. A new system now allows such objects to be printed at a much smaller scale than ever before.
-
A new study from NIST has tested how accurately commercial facial recognition algorithms can identify people wearing protective face masks, revealing some commercially used systems fail at authenticating masked faces up to 50 percent of the time.
-
In recent tests run by the National Institute of Standards and Technology (NIST), experimental atomic clocks have achieved record performance in three metrics, meaning these clocks could help measure the Earth’s gravity more precisely or detect elusive dark matter.

ScienceA US five-cent nickel can cost up to seven cents to make, so the US mint and the National Institute of Standards and Technology (NIST) are working on a version of the coin that is 40-percent cheaper, but is still as tough as the old one and maintains compatibility with modern vending machines.

Allowing scientists to make cut-and-paste edits to an organism’s genome, the CRISPR gene-editing tool may be powerful, but it’s still a bit clumsy. Now, researchers have developed a neater new version dubbed MAGESTIC, which they describe as swapping the scissors for a word processor.
-
Researchers have come up with a way to generate truly random numbers using quantum mechanics. The method uses photons to generate a string of random ones and zeros, and leans on the laws of physics to prove that these strings are truly random, rather than merely posing as random.

ScienceDespite what we see on TV and in movies, analyzing and matching latent prints is a difficult business and still the province of experts. But now scientists from NIST and Michigan State University are using algorithms and machine learning as a way to automate the process and make it more efficient.

ScienceThe definition of a kilogram hinges on the weight of a metal cylinder in a French vault, but plans are underway to redefine the kilogram in mathematical terms instead. To that end, a team at the National Institute of Standards and Technology (NIST) has submitted a precise new value of a key formula.
