Published With new heat treatment, 3D-printed metals can withstand extreme conditions
(via sciencedaily.com) A new way to 3D-print metals makes the materials stronger and more resilient in extreme thermal environments. The technique could lead to 3D printed high-performance blades and vanes for gas turbines and jet engines, which would enable improved fuel consumption and energy efficiency.
Published Researchers develop superfast new method to manufacture high-performance thermoelectric devices
(via sciencedaily.com) Aerospace and mechanical engineers have developed a machine-learning assisted superfast new way to create high-performance, energy-saving thermoelectric devices.
Published Plant fibers for sustainable devices
(via sciencedaily.com) Plant-derived materials such as cellulose often exhibit thermally insulating properties. A new material made from nanoscale cellulose fibers shows the reverse, high thermal conductivity. This makes it useful in areas previously dominated by synthetic polymer materials. Materials based on cellulose have environmental benefits over polymers, so research on this could lead to greener technological applications where thermal conductivity is needed.
Published Clear window coating could cool buildings without using energy
(via sciencedaily.com) As climate change intensifies summer heat, demand is growing for technologies to cool buildings. Now, researchers report that they have used advanced computing technology and artificial intelligence to design a transparent window coating that could lower the temperature inside buildings, without expending a single watt of energy.
Published Mathematicians explain how some fireflies flash in sync
(via sciencedaily.com) A new study by mathematicians shows that math borrowed from neuroscience can describe how swarms of these unique insects coordinate their light show, capturing key details about how they behave in the wild.
Published Looking to sea urchins for stronger ceramic foams
(via sciencedaily.com) New research has unlocked a mystery in the porous microstructures of sea urchin exoskeletons that could lead to the creation of lightweight synthetic ceramics.
Published Music class in sync with higher math scores -- but only at higher-income schools
(via sciencedaily.com) Music and arts classes are often first on the chopping block when schools face tight budgets and pressure to achieve high scores on standardized tests. But it's precisely those classes that can increase student interest in school and even benefit their math achievement, according to a new study.
Published Scientists discover material that can be made like a plastic but conducts like metal
(via sciencedaily.com) Scientists have discovered a way to create a material that can be made like a plastic, but conducts electricity more like a metal. The research shows how to make a kind of material in which the molecular fragments are jumbled and disordered, but can still conduct electricity extremely well. This goes against all of the rules we know about for conductivity.
Published Researchers create lunar regolith bricks that could be used to construct Artemis base camp
(via sciencedaily.com) As part of NASA's Artemis program to establish a long-term presence on the moon, it aims to build an Artemis base camp that includes a modern lunar cabin, rover and mobile home. This fixed habitat could potentially be constructed with bricks made of lunar regolith and saltwater, thanks to a recent discovery.
Published The next wonder semiconductor
(via sciencedaily.com) Original source In a study that confirms its promise as the next-generation semiconductor material, researchers have directly visualized the photocarrier transport properties of cubic boron arsenide single crystals.
Published High entropy alloys: Structural disorder and magnetic properties
(via sciencedaily.com) Original source High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic behavior. Now, a team has gained new insights into the local environment of a so-called high-entropy Cantor alloy made of chromium, manganese, iron, cobalt and nickel, and has thus also been able to partially explain the magnetic properties of a nanocrystalline film of this alloy.
Published Electronic gaming can trigger potentially lethal heart rhythm problems in susceptible children
(via sciencedaily.com) Electronic gaming can precipitate life-threatening cardiac arrhythmias in susceptible children whose predisposition may have been previously unrecognized, according to a new report. The investigators documented an uncommon, but distinct pattern among children who lose consciousness while playing electronic (video) games.
Published As few as 1 in 5 COVID cases may have been counted worldwide, mathematical models suggest
(via sciencedaily.com) Mathematical models indicate that as few as one in five cases of COVID-19 which occurred during the first 29 months of the pandemic are accounted for in the half billion cases officially reported.
Published Gamers can have their cake and eat it too
(via sciencedaily.com) New research from Japan shows that multiple cognitive abilities may be empirically measured from a complex game experience depending on the game's design.
Published The way you talk to your child about math matters
(via sciencedaily.com) 'You're so smart!' -- This encouraging response may actually do more harm than good to children's math performance, according to a new study. The study found that encouraging children with responses related to their personal traits or innate abilities may dampen their math motivation and achievement over time.
Published Reasons behind gamer rage in children are complex -- and children are good at naming them
(via sciencedaily.com) Children's outbursts of rage while playing digital games are causing both concern and public debate around the topic. Taking a novel approach to gamer rage, a new study examines the topic from a child's perspective, finding complex reasons for gamer rage in children.
Published A key role for quantum entanglement
(via sciencedaily.com) A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement -- offering much broader security guarantees than previous schemes.
Published 'Pulling back the curtain' to reveal a molecular key to The Wizard of Oz
(via sciencedaily.com) Many people and companies worry about sensitive data getting hacked, so encrypting files with digital keys has become more commonplace. Now, researchers have developed a durable molecular encryption key from sequence-defined polymers that are built and deconstructed in a sequential way. They hid their molecular key in the ink of a letter, which was mailed and then used to decrypt a file with text from a classic story.
Published 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.
Published Video games can help boost children's intelligence
(via sciencedaily.com) Scientists have studied how the screen habits of US children correlates with how their cognitive abilities develop over time. They found that the children who spent an above-average time playing video games increased their intelligence more than the average, while TV watching or social media had neither a positive nor a negative effect.
