Simulation of fast, accurate DNA sequencing through graphene nanopore

19-Jan-2016

Researchers at the National Institute of Standards and Technology (NIST) have simulated a new concept for rapid, accurate gene sequencing by pulling a DNA molecule through a tiny, chemically activated hole in graphene--an ultrathin sheet of carbon atoms--and detecting changes in electrical ...

Portable kit can recover traces of chemical evidence

11-Jan-2016

A chemist at the National Institute of Standards and Technology (NIST) has developed a portable version of his method for recovering trace chemicals such as environmental pollutants and forensic evidence including secret graves and arson fire debris. If successfully commercialized by industry, ...

New material for detecting photons captures more quantum information

07-Jan-2016

Detecting individual particles of light just got a bit more precise - by 74 picoseconds to be exact - thanks to advances in materials by National Institute of Standards and Technology (NIST) researchers and their colleagues in fabricating superconducting nanowires. Although 74 picoseconds may not ...

Ringing in a new way to measure and modulate trapped light

24-Dec-2015

Researchers working at the National Institute of Standards and Technology (NIST) have developed a novel way to noninvasively measure and map how and where trapped light vibrates within microscale optical resonators. The new technique not only makes for more accurate measurements but also allows ...

Measuring nanoscale features with fractions of light

07-Dec-2015

National Institute of Standards and Technology (NIST) researchers are seeing the light, but in an altogether different way. And how they are doing it just might be the semiconductor industry's ticket for extending its use of optical microscopes to measure computer chip features that are ...

It's a beauty: JILA's quantum crystal is now more valuable

09-Nov-2015

Physicists at JILA have made their "quantum crystal" of ultracold molecules more valuable than ever by packing about five times more molecules into it. The denser crystal will help scientists unlock the secrets of magnets and other, more exotic materials. The crystal is actually a gas of ...

Scientists float new approach to creating computer memory

12-Oct-2015

What can skyrmions do for you? These ghostly quantum rings, heretofore glimpsed only under extreme laboratory conditions, just might be the basis for a new type of computer memory that never loses its grip on the data it stores. Now, thanks to a research team including scientists from the ...

Twisting neutrons

25-Sep-2015

It's easy to contemplate the wave nature of light in common experience. White light passing through a prism spreads out into constituent colors; it diffracts from atmospheric moisture into a rainbow; light passing across a sharp edge or a diffraction grating creates an interference pattern. It's ...

NIST physicists show 'molecules' made of light may be possible

14-Sep-2015

It's not lightsaber time, not yet. But a team including theoretical physicists from the National Institute of Standards and Technology (NIST) has taken another step toward building objects out of photons, and the findings hint that weightless particles of light can be joined into a sort of ...

NIST calculates high cost of hydrogen pipelines, shows how to reduce it

22-Jul-2015

The National Institute of Standards and Technology (NIST) has put firm numbers on the high costs of installing pipelines to transport hydrogen fuel - and also found a way to reduce those costs.Pipelines to carry hydrogen cost more than other gas pipelines because of the measures required to ...
