High-energy physicists devoted to recreating the conditions at the beginning of the universe have for the first time observed a new way to produce those basic particles of atoms, protons and neutrons.
Ultracold atoms moving through a carefully designed arrangement of laser beams will jiggle slightly as they go, two NIST scientists have predicted.* If observed, this never-before-seen â€œjitterbugâ€ motion would shed light on a little-known oddity of quantum mechanics arising from Paul Diracâ€™s 80-year-old theory of the electron.
Using a virtual pendulum and its real-world counterpart, scientists at the University of Illinois have created the first mixed reality state in a physical system. Through bidirectional instantaneous coupling, each pendulum â€œsensedâ€ the other, their motions became correlated, and the two began swinging as one.
A clever new microscope design allows nanotechnology researchers at the National Institute of Standards and Technology (NIST) to track the motions of nanoparticles in solution as they dart around in three dimensions. The researchers hope the technology, which NIST plans to patent, will lead to a better understanding of the dynamics of nanoparticles in fluids and, ultimately, process control techniques to optimize the assembly of nanotech devices.
Researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland have developed a new optical method that can detect individual neutrons and record them over a range of intensities at least a hundred times greater than existing detectors.
Geologists at the University of Illinois have confirmed the discovery of Earthâ€™s inner, innermost core, and have created a three-dimensional model that describes the seismic anisotropy and texturing of iron crystals within the inner core.
ROCHESTER, Minn., March 10 /PRNewswire-USNewswire/ -- Thousands of research studies have documented how the oils known as omega-3 fatty acids can benefit the cardiovascular system, particularly among people diagnosed with coronary artery disease.
