  • 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.

    A 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.
  • Science
    Despite 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.
  • Science
    The 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.
  • Science
    In 2010, after spending billions on research, Pentagon officials admitted that there was no better bomb detector than a dog's nose. Now scientists say the reason for this might lie simply in the way they sniff.
  • Science
    Scientists have set a new world record for atomic clock stability using a pair of ytterbium-based timepieces stable down to quintillionths of a second. The researchers believe that their new system may prove invaluable in determining the precision of fundamental universal constants.
  • Researchers working at the National Institute of Standards and Technology (NIST) claim to have teleported the quantum information carried in light particles over 100 km (62 miles) of optical fiber, four times farther than the previous record.
