Manipulation of nanolight provides new insight for quantum computing and thermal management
A recent study led by University of Minnesota Twin Cities researchers provides fundamental insight into how light, electrons, and crystal vibrations interact in materials.
Superconductivity Is Unpredictable at the Edge
A recent study shows that the superconducting edge currents in the topological material molybdenum telluride (MoTe2) can sustain large changes in the "glue" that keeps the superconducting electrons paired. To sustain these changes, the bulk and the edge of MoTe2 must behave differently. This surprise finding will help researchers create and control anyons and aid in the development of future energy-efficient electronics.

A world first: Qubit coherence decay traced to thermal dissipation
Hitherto a mystery, the thermal energy loss of qubits can be explained with a surprisingly simple experimental setup, according to research from Aalto University.
Spherical Powders Enable New Applications for Metals
A newly developed process transforms large, irregular chunks of metal elements into uniform spherical particles that act like tiny ball bearings rolling past one another. This allows solid metals to be handled like a liquid. This process, the AMAZEMET rePowder(r) ultrasonic metal atomization process, works equally well for most metallic elements and their alloys.
Physicists shine new light on ultra-fast atomic processes
An international team of scientists is the first to report incredibly small time delays in a molecule's electron activity when the particles are exposed to X-rays.
Physics Today Takes a Look Inside the Physics Book Illustrated by a Teenage Maurice Sendak
Many childhoods have been shaped by the works of Maurice Sendak, whose deeply emotional stories and fantastical illustrations have captured the imaginations of millions.
Quenching the intense heat of a fusion plasma may require a well-placed liquid metal evaporator
New fusion simulations of the inside of a tokamak reveal the ideal spot for a "cave" with flowing liquid lithium is near the bottom by the center stack, as the evaporating metal particles should land in just the right spot to dissipate excess heat from the plasma.
An Improved Domino Chain for Sustainable Methanol Synthesis
Transforming carbon monoxide into an energy dense liquid fuel is hard to accomplish in a single step, so researchers instead use multi-step reactions. Recently, scientists improved this multi-step process by using recyclable organic reductants.
Why do plants wiggle? New study provides answers
Decades after his voyage on the HMS Beagle, Charles Darwin became fascinated by why plants move as they grow--spinning and twisting into corkscrews. Now, more than 150 years later, a new study may have solved the riddle.
Researchers observe "locked" electron pairs in a superconductor cuprate
The finding could help future efforts to design superconductors that work at higher temperatures.

A diverse group of 151 undergraduate students and eight faculty will participate in unique workforce development programs at 12 of the nation's national laboratories and a fusion facility during Fall 2024.
The More You Neutrino...
As a summer science writing intern in the Media and Communications Office at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, I learned about neutrinos while writing about Mary Bishai, an award-winning neutrino scientist.
Cerro Tololo captura deslumbrante cumulo galactico en Chile
La Camara de Energia Oscura obtuvo esta increible imagen del deslumbrante cumulo de Coma Berenice, que en la antiguedad se le asocio a la historia del cabello perdido que la Reina Berenice II de Egipto ofrecio a los dioses griegos como ofrenda por el retorno de su esposo de la guerra. Se trata de un conjunto de galaxias que no solo es significativo para la mitologia griega, sino tambien fue fundamental para el descubrimiento de la existencia de la materia oscura, cuando en 1937 el astronomo suizo Fritz Zwicky, noto que las galaxias de este cumulo se comportaban como si estuviesen bajo la influencia de enormes cantidades de materia invisible imposible de observar.
Queen Berenice II's Hair Tied Together by Dark Matter
The Dark Energy Camera captures an image of the dazzling Coma Cluster, named after the hair of Queen Berenice II of Egypt. Not only significant in Greek mythology, this collection of galaxies was also fundamental to the discovery of the existence of dark matter. The theory emerged in 1937 when Swiss astronomer Fritz Zwicky noticed that the Coma Cluster galaxies behaved as if they were under the influence of vast amounts of unobservable 'dark' matter.
Making the atomic universe visible
At Penn State and as a member of the Q-NEXT quantum research center, Nitin Samarth investigates atom-scale materials that could serve as the foundation for future quantum technologies.
"Mirror" Nuclei Help Connect Nuclear Theory and Neutron Stars
Scientists face challenges in their understanding of nuclei. For instance, they have not connected the description of the size of nuclei with the theory of the strong nuclear force, and it is not clear if theories of atomic nuclei can provide a reliable description of nuclear matter.
Cricket Physics: Science Behind the Modern Bowler Technique Tricking Batters
In Physics of Fluids, researchers have started to unravel the mysteries of how near-horizontal bowling in cricket leads to such tough-to-hit balls. The team employed a wake survey rake device made of multiple tubes designed to capture the pressure downstream of the ball and examined the flow dynamics of cricket balls rotating up to 2,500 rpm in a wind tunnel. The group found that low-pressure zones expanded and intensified near the ball when spinning, while these zones shifted and diminished downstream. At higher spin rates, the low-pressure zone begins to change to a persistent bilobed shape. The results lend support to the theory that these newer bowling techniques tap into the Magnus effect.
The mother of all motion sensors
For the first time, researchers from Sandia National Laboratories have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable.

Powering Enzymes with Light to Make Ammonia
Converting dinitrogen into ammonia is critical for making fertilizer. Conventional conversion processes use adenosine triphosphate (ATP). Researchers are now working on processes that instead use sunlight, which reduces energy use and greenhouse gas production relative to the ATP process. In this research, scientists created a unique biohybrid that couples nanocrystals to nitrogen-catalyzing enzymes to produce ammonia using sunlight.
