Posted: 08 Jul 2021 02:03 PM PDT

Are new nickelate superconductors close kin to the original high-temperature superconductors, the cuprates? The first study of their magnetic properties says the answer is yes. Scientists have found important similarities but also subtle differences between the two.

Remotely-piloted sailboats monitor 'cold pools' in tropical environments

Posted: 08 Jul 2021 02:03 PM PDT

Researchers used remotely-piloted sailboats to gather data on cold air pools, or pockets of cooler air that form when rain evaporates below tropical storm clouds. These hard-to-study phenomena are thought to have broader effects on tropical weather.

The pressure is off and high temperature superconductivity remains

Posted: 08 Jul 2021 02:03 PM PDT

Using a new pressure quenching (PQ) technique at high temperatures to induce superconductivity in iron selenide (FeSe) crystals, superconductivity was achieved -- and sustained -- without pressure.

Solving the plastic shortage with a new chemical catalyst

Posted: 08 Jul 2021 11:38 AM PDT

In a year that has already battered manufacturing supply chains, yet another shortage is complicating manufacturers' and consumers' lives: plastics, and the food packaging, automotive components, clothing, medical and lab equipment and countless other items that rely on them.

Icequakes likely rumble along geyser-spitting fractures in Saturn's icy moon Enceladus

Posted: 08 Jul 2021 10:53 AM PDT

Tidal stresses may be causing constant icequakes on Saturn's sixth largest moon Enceladus, a world of interest in the search for life beyond Earth, according to a new study.

Handwriting beats typing and watching videos for learning to read

Posted: 08 Jul 2021 08:15 AM PDT

Though writing by hand is increasingly being eclipsed by the ease of computers, a new study finds we shouldn't be so quick to throw away the pencils and paper: handwriting helps people learn certain skills surprisingly faster and significantly better than learning the same material through typing or watching videos.

New radio receiver opens wider window to radio universe

Posted: 08 Jul 2021 08:15 AM PDT

Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider than conventional ones, and can detect radio waves emitted by many types of molecules in space at once. This is expected to enable significant progresses in the study of the evolution of the Universe and the mechanisms of star and planet formation.

An antioxidative stress regulator protects muscle tissue in space, mouse study shows

Posted: 08 Jul 2021 08:14 AM PDT

Researchers have found that nuclear factor E2-related factor 2, a master regulator of the oxidative stress response, affects muscle composition in microgravity. Targeting this protein could help protect against muscle changes during space flight, and could also have implications for muscle wasting in conditions such as cancer and aging.

Collective battery storage beneficial for decarbonized world

Posted: 08 Jul 2021 07:36 AM PDT

Batteries are potentially a game-changing technology as we decarbonize our economy, and their benefits are even greater when shared across communities, a new study has found.

To predict underwater volcano eruptions, scientist looks at images from space

Posted: 08 Jul 2021 07:36 AM PDT

A new study monitored satellite images to obtain sea discoloration data as a novel indicator in detecting if an underwater volcano's eruption is imminent.

Unlocking radiation-free quantum technology with graphene

Posted: 08 Jul 2021 07:36 AM PDT

'Heavy fermions' are an appealing theoretical way to produce quantum entangled phenomena, but until recently have been observed mostly in dangerously radioactive compounds. Researchers have now shown it is possible to make heavy fermions in subtly modified graphene, which is much cheaper and safer.

Simulations of turbulence's smallest structures

Posted: 08 Jul 2021 07:36 AM PDT

Scientists have long used supercomputers to better understand how turbulent flows behave under a variety of conditions. Researchers have now include the complex but essential concept of 'intermittency' in turbulent flows.

More EVs could reduce CO2 emissions in Hawaii by 93% in less than 30 years

Posted: 07 Jul 2021 03:53 PM PDT

By 2050, faster adoption of electric vehicles (EVs) and faster generation of renewable energy will result in 99% less fossil fuel consumed and 93% less CO2 emissions from passenger and freight vehicles on Oahu.

Researchers record brainwaves to measure 'cybersickness'

Posted: 07 Jul 2021 01:05 PM PDT

In a new study, researchers used electroencephalography to better understand and work toward solutions for virtual reality-induced discomfort.

Quantum particles: Pulled and compressed

Posted: 07 Jul 2021 01:05 PM PDT

Only recently researchers have levitated and cooled nanoparticles into the quantum regime. A research team now proposes a way to harness the quantum properties of such particles before they lose them due to decoherence. To this end, the wave function of the particle is repeatedly expanded and compressed.

Study gauges hospital preparedness for the next national medical crisis

New study shows mathematical models helped reduce the spread of COVID-19

Posted: 07 Jul 2021 10:30 AM PDT

Researchers have published new findings that take a first look at the use of SARS-CoV-2 mathematical modeling to inform early statewide policies enacted to reduce the spread of the coronavirus pandemic in Colorado. Among other findings, the authors estimate that 97 percent of potential hospitalizations across the state in the early months of the pandemic were avoided as a result of social distancing and other transmission-reducing activities such as mask wearing and social isolation of symptomatic individuals.
