First room-temp 'magnon switch' with industrially useful properties
Scientists have demonstrated a practical technique for controlling magnons, which could lead to computer chip switches that would use less energy and radiate less heat. The approach brings two important...
Researchers create first room-temp 'magnon switch' with industrially useful properties
Scientists at the National Institute of Standards and Technology (NIST) and the Massachusetts Institute of Technology (MIT) have demonstrated a potentially new way to make switches inside a computer's processing...
'Jurassic World: Dominion' plans to resume filming in July
"Jurassic World: Dominion," starring Chris Pratt and Bryce Dallas Howard, is slated to to start production again in the United Kingdom.
A phase battery for quantum technologies
Batteries belongs to everyday life. A classical battery, the Volta's pile, converts chemical energy into a voltage, which can power electronic circuits. In many quantum technologies, circuits or devices are...
Melting a crystal topologically
The introduction of topology, a branch of mathematics focusing on the properties of 'knots,' into physics has inspired revolutionary concepts such as topological phases of matter and topological phase transitions,...
When board members get involved, corporate tax burden goes down
New research finds that corporate tax-planning practices improve when a company's board takes an interest in tax-planning practices—and better planning results in both less tax uncertainty and a lower tax...
Research reveals how material defects influence melting process
In 1972, physicists J. Michael Kosterlitz and David Thouless published a groundbreaking theory of how phase changes could occur in two-dimensional materials. Experiments soon showed that the theory correctly captured...
Radiation pressure with recoil: Experimental proof for a 90 year-old theory
Light exerts a certain amount of pressure onto a body: sun sails could thus power space probes in the future. However, when light particles (photons) hit an individual molecule and...
Excitons form superfluid in certain 2-D combos
Mixing and matching computational models of 2-D materials led scientists at Rice University to the realization that excitons—quasiparticles that exist when electrons and holes briefly bind—can be manipulated in new...
Using Jenga to explain lithium-ion batteries
Tower block games such as Jenga can be used to explain to schoolchildren how lithium-ion batteries work, meeting an educational need to better understand a power source that has become...
Artificial synapse that works with living cells created
Researchers have created a device that can integrate and interact with neuron-like cells. This could be an early step toward an artificial synapse for use in brain-computer interfaces.
'Gone with the Wind' to return to HBO Max with introduction from black scholar Jacqueline Stewart
"Gone with the Wind" is set to return to HBO Max with a new introduction from black scholar and television host Jacqueline Stewart.
New tool to measure aerosol optical hygroscopicity
Researchers at Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science recently developed a humidified cavity-enhanced albedometer (H-CEA) which could simultaneously measure relative-humidity-dependent aerosol light extinction, scattering,...
Hemp and maple work together to power these high-end headphones
The Hemp Headphones use the familiar Grado design. (Grado/)Brooklyn-based headphone maker Grado is no stranger to replacing plastic or metal with wood in its high-end products. The company’s high-end Reference Series headphones employ...
Salt solution produces better organic electrochemical transistors
Doping is commonly used to improve performance in semiconducting devices but has not previously been successful for electron transporting or n-type, organic electronic materials. Now, an approach developed by KAUST...
Probing dark matter with the Higgs boson
Visible matter—everything from pollen to stars and galaxies—accounts for roughly 15% of the total mass of the universe. The remaining 85% is made of something entirely different from things we...
A quantum memory that operates at telecom wavelengths
To create large quantum networks, researchers will first need to develop efficient quantum repeaters. A key component of these repeaters are quantum memories, which are the quantum-mechanical equivalents of more...
Current-voltage curve of graphene nanoribbons measured, with implications for graphene switches
Researchers at Japan Advanced Institute of Science and Technology (JAIST) have successfully measured the current-voltage curve of graphene nanoribbons (GNRs) that were suspended between two electrodes. Measurements were performed using...
Cutting-edge computing paves way to future of NMR spectroscopy
Nuclear magnetic resonance (NMR) spectroscopy helps chemists and other scientists identify and explore atomic structures. However, NMR is limited by the availability of catalogs of reference data to compare and...
Newly observed phenomenon could lead to new quantum devices
An exotic physical phenomenon known as a Kohn anomaly has been found for the first time in an unexpected type of material by researchers at MIT and elsewhere. They say...
Science strike for Black Lives Matter
Bob McDonald's blog: Universities shut down research for a day to focus on how to eliminate anti-Black racism.
