The Washington Football Team has released running back Derrius Guice, less than two hours after the former LSU tailback was arrested on domestic violence charges.
Highly sensitive dopamine detector uses 2-D materials
A supersensitive dopamine detector can help in the early diagnosis of several disorders that result in too much or too little dopamine, according to a group led by Penn State...
Materials science researchers develop first electrically injected laser
Materials science researchers, led by electrical engineering professor Shui-Qing "Fisher" Yu, have demonstrated the first electrically injected laser made with germanium tin.
Navy, Air Force hold joint exercises with aircraft carrier USS Ronald Reagan
Led by the aircraft carrier USS Ronald Reagan, the Air Force and Navy held joint training exercises this week near Japan, the 7th Fleet announced.
Authors' 'invisible' words reveal blueprint for storytelling
The "invisible" words that shaped Dickens classics also lead audiences through Spielberg dramas. And according to new research, these small words can be found in a similar pattern across most...
Scientists develop principles for the creation of an 'acoustic diode'
In research published in Science Advances, a group led by scientists from the RIKEN Center for Emergent Matter Science (CEMS) have used the principle of magneto-rotation coupling to suppress the...
U.S. Air Force holds electronic warfare exercise with classified stealth drone
The U.S. Air Force this week concluded a test of tactics with its highly classified RQ-170 surveillance drone with other stealth aircraft, including the B-2 bomber, F-15, F-22, F-35 and...
A new experiment hints at how hot water can freeze faster than cold
In physics, chilling out isn’t as simple as it seems. A hot object can cool more quickly than a warm one, a new study finds. When chilled, a warmer system cooled off...
Look: Lily James, Armie Hammer star in Netflix's 'Rebecca' remake
"Rebecca," a new film based on the Daphne du Maurier novel, will premiere Oct. 21 on Netflix.
Making N-C bonds directly from dinitrogen: Summary and perspective
As the most abundant constituent in Earth's atmosphere, dinitrogen (N2) is the main nitrogen source of N-containing compounds in the Earth. Therefore, N2 fixation and activation are essential both for...
Measuring electron emission from irradiated biomolecules
When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionize the molecules even further. To fully understand how biological...
Electric cars won't save us if the numbers don't add up—economist
Electric cars are one of the fastest growing sectors of the automotive industry. Record sales are being made despite the economic crisis posed by the coronavirus pandemic. Seven years ago,...
Measuring electron emission from irradiated biomolecules
Researchers have successfully determined the characteristics of electron emission when high-velocity ions collide with adenine - one of the four key nucleobases of DNA.
Updating Turing's model of pattern formation
New research revisits the Turing instability mechanism; proving mathematically how the instabilities which give rise to patterns can occur through simple reactions, and in widely varied environmental conditions.
New-generation carbon dioxide gas separation system using gate-type adsorbents
The Paris Agreement of 2015 set a goal of reducing CO2 emissions, a greenhouse gas that has caused global warming to levels of less than 2°C more than before the...
A titanate nanowire mask that can eliminate pathogens
Researchers are working on a membrane made of titanium oxide nanowires, similar in appearance to filter paper but with antibacterial and antiviral properties. Their material works by using the photocatalytic...
Origins of life: Chemical evolution in a tiny Gulf Stream
Chemical reactions driven by the geological conditions on the early Earth might have led to the prebiotic evolution of self-replicating molecules. Scientists now report on a hydrothermal mechanism that could...
Origins of life: Chemical evolution in a tiny Gulf Stream
Chemical reactions driven by the geological conditions on the early Earth might have led to the prebiotic evolution of self-replicating molecules. Scientists at Ludwig-Maximilians Universitaet (LMU) in Munich now report...
Algorithm predicts the compositions of new materials
A machine-learning algorithm that can predict the compositions of trend-defying new materials has been developed by RIKEN chemists1. It will be useful for finding materials for applications where there is...
Glass-like wood insulates heat, is tough, blocks UV and has wood-grain pattern
Need light but want privacy? A new type of wood that's transparent, tough, and beautiful could be the solution. This nature-inspired building material allows light to come through (at about...
'Roaming reactions' study to shed new light on atmospheric molecules
For the first time, a team of chemists has lifted the hood on the mechanics involved in the mysterious interplay between sunlight and molecules in the atmosphere known as 'roaming...
UCLA coach Chip Kelly tested positive for coronavirus early in the pandemic
UCLA football coach Chip Kelly contracted the novel coronavirus in March and has since recovered after experiencing mild symptoms.
Chemists build natural anti-cancer compound with lean new process
Creative chemists employ enzymes to build a complex but promising natural anti-cancer agent called cepafungin I in a lean nine steps.
Electric cooker an easy, efficient way to sanitize N95 masks, study finds
A new study found that 50 minutes of dry heat in an electric cooker decontaminated N95 respirators inside and out while maintaining their filtration and fit. This could enable wearers...
Why shaving dulls even the sharpest of razors
Engineers have studied the simple act of shaving up close, observing how a razor blade can be damaged as it cuts human hair -- a material that is 50 times...
