Newton’s Cradle Yields Insight into Quantum Thermalization STANFORD, Calif., May 3, 2018 — A quantum version of Newton’s cradle was used to investigate how the chaotic motion of quantum particles eventually leads to thermal equilibrium. With the cradle, researchers observed how, after inducing small amounts of chaotic motion, a quantum system reaches thermal equilibrium. Researchers from Stanford University created a one-dimensional Bose gas with strong magnetic dipole-dipole interactions. A laser beam was shined through an airtight chamber to cool the gas to nearly
Camera Can Differentiate Between Exoplanet Light and Nearby Starlight SANTA BARBARA, Calif., May 2, 2018 — A new superconducting camera will be used in the search for exoplanets that could contain or support life. Distinguishing the light of a planet from the light of the star it orbits is a challenge, which the camera’s high-contrast imaging...
Optogenetic Tool Controls Voltage-Gated Calcium Channels COLLEGE STATION, Texas, May 2, 2018 — An optogenetic tool has been developed for controlling voltage-gated calcium (CaV) channels to enable photo-tunable modulation of CaV channel activity in excitable mammalian cells. The tool, called optoRGK, provides a way to interrogate the...
Device Uses Light to Reprogram Gene Expression COLLEGE STATION, Texas, May 1, 2018 — Researchers at Texas A&M have developed a chemical or light-inducible transcriptional reprogramming device to illuminate the functions of genes during different biological processes, using calcium and light. The CaRROT system (calcium-responsive...
Managing Chronic Pain with Light ROME, April 27, 2018 — Researchers have developed a light-based method that could be used to manage neuropathic pain. The technique was tested in mice. Researchers from the European Molecular Biology Laboratory (EMBL) Rome identified a specific population of nerve cells...
New Platform Brings Photonics to Bulk Silicon Microelectronic Chips BROOKLINE, Mass., April 26, 2018 — A microchip technology that is capable of optically transferring data could alleviate bottlenecks in current devices by speeding data transfer and reducing energy consumption by orders of magnitude. The new method that has been developed for...
Researchers Confine Light to Space of One Atom in Nanophotonics Advance BARCELONA, Spain, April 25, 2018 — Using graphene, researchers have found a way to confine light down to a space that is one atom thick. The ability to confine light to such a small space could pave the way for ultrasmall optoelectronic devices. Previous work has shown that while...
UV Light Exposure Causes Composite Material to Grow Stronger On Demand ABERDEEN PROVING GROUND, Md., April 24, 2018 — A technique has been developed that causes a composite material to become stiffer and stronger when exposed to UV light. The technique can be controlled, allowing the strength of the material to be adapted to the requirements of the application. To...
AO-LLSM Microscope Achieves Aberration-Free Imaging Across Large Volumes ASHBURN, Va., April 23, 2018 — Scientists have combined lattice light-sheet microscopy (LLSM) with adaptive optics (AO) to capture high-resolution 3D movies of cells deep within living systems. The AO-LLSM microscope enables cells to be viewed in their native multicellular...
Short, Strong Laser Pulses Advance Understanding of Strongly Correlated Materials BERLIN, Germany, April 20, 2018 — In its search for materials and technologies that could help push the speed and storage limits of silicon-based computer technology, a team of researchers looked at a category of materials known as “strongly correlated systems,” so called because of...
Seaweed Forms Dynamic Opal-Like Photonic Nanostructures BRISTOL, England, April 20, 2018 — Intracellular opal-like photonic crystals, formed from lipids within photosynthetic cells, have been observed to produce vivid structural color in the algae Cystoseira tamariscifolia. The bright blue and green iridescent sheen from the brown algae...
Whispering Gallery for Light Boosts Solar Cell Absorption and Photocurrent GAITHERSBURG, Md., April 18, 2018 — Researchers have developed a nanoscale coating for solar cells that enables the cells to absorb about 20 percent more sunlight than uncoated devices. The coating, developed by trapping light using an optical version of a whispering gallery, could...
New Bose-Einstein Condensate Couples Light with Metal Electrons ESPOO, Finland, April 18, 2018 — Researchers created a new Bose-Einstein condensate, where the condensed particles were mixtures of light and metal electrons (so-called surface plasmon polaritons), in motion in gold nanorods arranged into a periodic array. Unlike most previous...
New Book Addresses Issues, Offers Solutions for LOS Control PITTSFIELD, Mass., April 17, 2018 — In Stabilizing the Line of Sight, authors Peter J. Kennedy and Rhonda L. Kennedy provide a methodology and an example for executing a successful end-to-end LOS design. Comprehensive in scope, this book will give readers a better understanding of the...
Researchers Attain Largest Entangled Quantum Register to Date INNSBRUCK, Austria, April 16, 2018 — A research team at the Institute of Quantum Optics and Quantum Information (IQOQI) in Innsbruck, together with researchers from the University of Ulm and the Institute of Quantum Optics and Quantum Information (Vienna), has achieved controlled...
Optofluidic Smart Glass System Is Cost-Efficient, High Performing NEWARK, Del., April 16, 2018 — Smart glass panels that can switch between allowing light in and blocking it out could one day be used in eco-friendly windows, windshields, roof panes and building envelopes to absorb light and heat in cold weather and reflect heat away from...
Tiny Fiber Optic Probe Senses Body Temps, Performs OCT Imaging ADELAIDE, Australia, April 16, 2018 — A miniaturized fiber optic probe has been invented that can simultaneously measure body temperature and take images deep inside the body. The single-fiber-based image and sensing probe uses an OCT lens fabricated at the distal end of a double-clad...
Plant Protein Powers Red Light-Activated Switch for Animal Cells LA JOLLA, Calif., April 11, 2018 — An optogenetic switch activated by red and far-red light has been designed and tested in animal cells. The light-activated switch, which does not require the addition of sensing molecules from outside the cells, could be used to turn genes on and...
Technique to Suppress Photobleaching Increases Imaging Window OKINAWA, Japan, April 10, 2018 — To better understand how proteins move and interact within the cell membrane, an imaging method called live-cell single fluorescent-molecule imaging (SFMI) can be used to tag each protein in the membrane individually with fluorescent markers. The...
Van Gils Appointed as VTT Research Professor ESPOO, Finland, April 10, 2018 — VTT Technical Research Centre of Finland has appointed Mark van Gils as research professor in charge of artificial intelligence in wellness and health care.
