AI used to show how hydrogen becomes a metal inside giant planets
Researchers have used a combination of AI and quantum mechanics to reveal how hydrogen gradually turns into a metal inside giant planets.
Physicists use classical concepts to decipher strange quantum behaviors in an ultracold gas
There they were, in all their weird quantum glory: ultracold lithium atoms in the optical trap operated by UC Santa Barbara undergraduate student Alec Cao and his colleagues in David...
Northrop Grumman nets $13.3B to develop Minuteman 3 ICBM replacement
The Air Force has awarded a $13.3 billion contract to Northrop Grumman for the Ground Based Strategic Deterrent, the new ICBM system that will replace the Minuteman 3 system in...
UN report: Increased warming closing in on agreed upon limit
The world is getting closer to passing a temperature limit set by global leaders five years ago and may exceed it in the next decade or so, according to a...
A Janus emitter for passive heat release from enclosures
It is presently challenging to efficiently cool enclosed spaces such as stationary automobiles that trap heat via the greenhouse effect. In a new report in Science Advances, Se-Yeon Heo and...
Establishment of a rapid synthesis method for useful organic fluorine compounds
The Nagoya University Institute of Transformative Bio-Molecules (WPI-ITbM) research team of Professor Cathleen Crudden, Designated Lecturer Masakazu Nambo, JSPS Postdoctoral Fellow Yuki Maekawa and Associate Professor Daisuke Yokogawa have developed...
Lockdown did not reduce 'most harmful' type of air pollution in Scotland
The significant reduction in vehicle journeys during the COVID-19 lockdown did not reduce the level of toxic fine particles in Scotland's air, according to experts at the University of Stirling.
New glove-like device mimics sense of touch
Engineers have invented a soft wearable device which simulates the sense of touch and has wide potential for medical, industrial and entertainment applications.
Technique prevents errors in quantum computers
Even quantum computers make mistakes. Their computing ability is extraordinary, exceeding that of classical computers by far. This is because circuits in quantum computers are based on qubits that can...
AI used to show how hydrogen becomes a metal inside giant planets
Dense metallic hydrogen—a phase of hydrogen which behaves like an electrical conductor—makes up the interior of giant planets, but it is difficult to study and poorly understood. By combining artificial...
Ontario sees drop in new COVID-19 cases, but testing levels plunge
The drop, though, comes as the number of test samples for the novel coronavirus processed by the province's labs fell below 18,000 for first time since August 5.
Blood and Silicon: New Electronics-Cooling System Mimics Human Capillaries
Microchannels strategically carved in chips could help meet demand for ever-smaller devices and cut energy use -- Read more on ScientificAmerican.com
The presence of resonating cavities above sunspots has been confirmed
Sunspots are darker regions which often appear on the Sun's surface. They are caused by strong concentrations of magnetic field, and can be as big as the Earth, or even...
Magnetic whirls crystallize in two dimensions
In a collaboration between experimental physicists and theoretical physicists in the framework of the Dynamics and Topology (TopDyn) excellence project, a system of many small magnetic whirls could be engineered...
Mineral undergoes self-healing of irradiation damage
Several minerals suffer radioactive self-irradiation and experience long-term changes to their properties. The mineral monazite behaves like Camembert cheese in which holes are drilled: existing radiation damage heals itself. An...
A gold nanoparticle nearly cloaked by a single molecule
A team of researchers from the Max Planck Institute for the Science of Light and Friedrich-Alexander University Erlangen has found a way to prove a theory suggesting the possibility of...
Researchers design system to visualize objects through clouds and fog
Like a comic book come to life, researchers at Stanford University have developed a kind of X-ray vision—only without the X-rays. Working with hardware similar to what enables autonomous cars...
Researchers fabricate high-quality transparent ceramic
Mid-infrared lasers have been widely used in imaging, detection, diagnostics, environmental monitoring, medicine, industry, defense and others. For mid-infrared laser systems, low phonon energy gain materials are key factors.
How Ottawa hopes to supercharge Canada's hydrogen fuel sector
For decades, hydrogen has been referred to as the fuel of the future. But that might change this fall if the federal government releases its hydrogen fuel strategy as planned.
Verifying whisky using laser light
Researchers from the University of St Andrews have developed an innovative new technique using lasers to accurately measure the authenticity of some of the world's most exclusive whiskies—without ever removing...
New computational model stands to make nuclear magnetic resonance an even more powerful tool for researchers
Scientists at the U.S. Department of Energy's Ames Laboratory have developed a new computational model that has opened up the potential to make one of their most powerful research tools...
Novel photocatalysts can perform solar-driven conversion of carbon dioxide into fuel
Scientists at Daegu Gyeongbuk Institute of Science and Technology, Korea, develop a novel "heterostructured" photocatalyst using titanium and copper, two abundant and relatively inexpensive metals. Their cost-effective synthesis procedure, coupled...
First U.S. Small Nuclear Reactor Design Is Approved
Concerns about costs and safety remain, however -- Read more on ScientificAmerican.com
New microfluidic device minimizes loss of high value samples
A major collaborative effort that has been developing over the last three years between ASU and European scientists, has resulted in a significant technical advance in X-ray crystallographic sample strategies.
Scientists probe the chemistry of a single battery electrode particle both inside and out
The particles that make up lithium-ion battery electrodes are microscopic but mighty: They determine how much charge the battery can store, how fast it charges and discharges and how it...

Christian McCaffrey and Dalvin Cook top UPI senior sports writer Alex Butler's Week 1 fantasy football running back rankings.
Army adopts new tech to detect chemical weapons
Researchers have developed a product to detect chemical weapons accurately at lower concentration levels -- and can help inspectors determine whether decontamination worked.
Scientists probe the chemistry of a single battery electrode particle both inside and out
Cracks and chemical reactions on a battery particle's surface can degrade performance, and the particle's ability to absorb and release lithium ions also changes over time. Scientists stuck a single...
