Devices that capture the brilliant light from millions of quantum dots, including chip-scale lasers and optical amplifiers, have made the transition from
Perched atop a high plateau in Chile’s Atacama Desert, a long-awaited observatory is beginning to take shape: the largest suite of ground-based telescopes
The National Institute of Standards and Technology (NIST) is the United States’ premier standards and measurements laboratory. NIST’s numerous varied and wide
Fruits and vegetables brought in from outside the country first require health and foodborne pathogen inspections. NIST research chemist Ileana Pazos helps the
For decades, astronomers and physicists have been trying to solve one of the deepest mysteries about the cosmos: An estimated 85% of its mass is missing.
Each year, hundreds of meteorites — rocky bodies left over from the formation of the solar system — bombard Earth, delivering minerals, metals and water to our
A picture may be worth a thousand words, but for astronomers, simply recording images of stars and galaxies isn’t enough. To measure the true size and absolute
Space-time ripples, exploding stars, colliding black holes …. and the National Institute of Standards and Technology? NIST doesn’t exactly come to mind when
A new way of imaging concealed objects, devised by a researcher at the National Institute of Standards and Technology (NIST) and his colleagues, might take all
Shine a flashlight into murky pond water and the beam won’t penetrate very far. Absorption and scattering rapidly diminishes the intensity of the light beam
Jeffrey Herrera is one of NIST’s health physicists, ensuring our ability to safely use radioactive materials for research and supporting radiation safety
The 19th International Workshop on Low Temperature Detectors (LTD19) was an opportunity for researchers from around the world to exchange information about the
For some 30 years, scientists have used superconducting materials to record the tiniest specks of light imaginable — individual photons, or single particles of
From the stars to the Lilliputian — a new camera lens using the power of reflection has the potential to transform neutron imaging. Wolter optics, named after
Dating can be complicated. Our team uses this instrument — a live-timed anticoincidence counter — to figure the decay rate of an isotope, which we can then use
GAITHERSBURG, Md. — The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) held a ribbon-cutting ceremony yesterday to unveil a
Look at an astronomical marvel like the Cat’s Eye Nebula at right, with an average gas temperature about twice as hot as the surface of the Sun. It seems
Researchers at the National Institute of Standards and Technology (NIST) have published landmark test results that suggest a promising class of sensors can be
Catching cancer early can make all the difference for successful treatment. A common screening practice measures tumor growth with X-ray computed tomography (CT
It is often the case that a valuable new industrial capability brings with it a whole new set of challenges for measurement science -- and thus, inevitably, for
Neutron detectors and sources play critical roles in national defense, homeland security, nuclear power plant control, radiation medicine, petroleum exploration
