Sparking sustainable new chemical catalysts      (via sciencedaily.com) 

New research could lead to the creation of new, sustainable catalysts based on tungsten oxide and similar compounds. The project used computational simulations to understand how tungsten oxide interacts with hydrogen at the molecular level and the findings were verified through lab experimentation.

Physicists explain how type of aurora on Mars is formed      (via sciencedaily.com) 

Researchers have learned how a type of aurora on Mars is formed. The physicists report discrete aurora form through the interaction of the solar wind and the crust at Mars' southern hemisphere.

Nuclear physics and extreme environments of cosmic explosions      (via sciencedaily.com) 

Researchers have helped peer inside a nova -- a type of astrophysical nuclear explosion -- without leaving Earth. These stellar events help forge the universe's chemical elements, and astronomers have explored their nature with an intense isotope beam and a custom experimental device with record-setting sensitivity.

Astronauts may one day drink water from ancient moon volcanoes      (via sciencedaily.com) 

If any humans had been alive 2 to 4 billion years ago, they may have looked up and seen a sliver of frost on the moon's surface. Some of that ice may still be hiding in craters on the lunar surface today.

Ancient tooth unlocks mystery of Denisovans in Asia      (via sciencedaily.com)     Original source 

What links a finger bone and some fossil teeth found in a cave in the remote Altai Mountains of Siberia to a single tooth found in a cave in the limestone landscapes of tropical Laos? The answer to this question has been established by an international team of researchers from Laos, Europe, the US and Australia. The human tooth was chanced upon during an archaeological survey in a remote area of Laos. The scientists have shown it originated from the same ancient human population first recognised in Denisova Cave (dubbed the Denisovans), in the Altai Mountains of Siberia (Russia).

Algorithms empower metalens design      (via sciencedaily.com) 

Researchers have developed a new method for designing large-scale metasurfaces that uses techniques of machine intelligence to generate designs automatically. The method will enable new metasurface designs that can make an impact on virtual or augmented reality, self-driving cars, and machine vision for embarked systems and satellites.

Improved wind forecasts save consumers millions in energy costs      (via sciencedaily.com) 

Scientists determined that by increasing the accuracy of weather forecasts over the last decade, consumers netted at least $384 million in energy savings. The researchers based their predictions on NOAA's High Resolution Rapid Refresh model, which provides daily weather forecasts for every part of the U.S. These include wind speed and direction data, which utilities can use to gauge how much energy their turbines will produce.

The numbers don't lie: Australia is failing at maths and we need to find a new formula to arrest the decline      (via sciencedaily.com) 

Australia has suffered a significant drop in teenage maths proficiency in the past 20 years -- sliding from 11th in the OECD rankings to 29th place out of 38 countries, prompting widespread debate over potential curriculum changes. One researcher says hand gestures could stop the slide.

Validation brings new predictive capability to global megafire smoke impacts      (via sciencedaily.com) 

New research modeling smoke from two recent megafires sets the stage for better forecasting of how emissions from these global-scale events will behave and impact temperatures. As huge wildfires become more common under climate change, increased attention has focused on the intensity and duration of their emissions, which rival those of some volcano eruptions.

Mars' emitted energy and seasonal energy imbalance      (via sciencedaily.com) 

Seasonal imbalance between the solar energy absorbed and released by the planet Mars could be a cause of the Red Planet's dust storms, according to new research. Understanding how the system works on Mars could help scientists predict how climate change could affect Earth.

Eavesdroppers can hack 6G frequency with DIY metasurface      (via sciencedaily.com) 

Crafty hackers can make a tool to eavesdrop on some 6G wireless signals in as little as five minutes using office paper, an inkjet printer, a metallic foil transfer and a laminator.

Extraterrestrial stone brings first supernova clues to Earth      (via sciencedaily.com) 

The extraterrestrial Hypatia stone found in Egypt could be the first tangible evidence on Earth of a supernova type Ia explosion. These rare supernovas are some of the most energetic events in the universe. If the hypothesis is correct, Hypatia would be a 'forensic' clue of an epic cosmic story started sometime in the early formation of our solar system.

Going gentle on mechanical quantum systems      (via sciencedaily.com) 

Systems in which mechanical motion is controlled at the level of individual quanta are emerging as a promising quantum-?technology platform. New experimental work now establishes how quantum properties of such systems can be measured without destroying the quantum state -- a key ingredient for tapping the full potential of mechanical quantum systems.

New study indicates limited water circulation late in the history of Mars      (via sciencedaily.com) 

A research team has investigated a meteorite from Mars using neutron and X-ray tomography. The technology, which will probably be used when NASA examines samples from the Red Planet in 2030, showed that the meteorite had limited exposure to water, thus making life at that specific time and place unlikely.

Hunga volcano eruption provides an explosion of data      (via sciencedaily.com) 

The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also created an atmospheric pulse that caused an unusual tsunami-like disturbance that arrived at Pacific shores sooner than the actual tsunami.

When quan­tum par­ti­cles fly like bees      (via sciencedaily.com) 

A quantum system with only 51 charged atoms can take on more than two quadrillion different states. Calculating the system's behavior is child's play for a quantum simulator. But verifying the result is almost impossible, even with today's supercomputers. A research team has now shown how these systems can be verified using equations formulated in the 18th century.

Study finds realism a key factor in driving engagement with virtual reality videos      (via sciencedaily.com) 

A recent study finds that realism is a key factor in determining whether viewers engage with virtual reality videos -- and that engagement is itself a key factor in determining whether viewers are interested in watching VR videos in the future.
