Published Study examines potential use of machine learning for sustainable development of biomass
(via sciencedaily.com) Original source Machine learning can be valuable in supporting sustainable development of biomass if it is applied across the entire lifecyle of biomass and biomass-derived products, according to a new study.
Published Gas monitoring at volcanic fields outside Naples, Italy, exposes multiple sources of carbon dioxide emissions
(via sciencedaily.com) The Phlegraean volcanic fields just west of Naples, Italy, are among the top eight emitters of volcanic carbon dioxide in the world. Since 2005, the Solfatara crater -- one of many circular depressions in the landscape left by a long history of eruptions --has been emitting increased volumes of gas. Today it emits 4,000-5,000 tons of carbon dioxide each day, equivalent to the emissions from burning ~500,000 gallons of gasoline. Researchers estimate that as much as 20%--40% of the current carbon dioxide emissions are from the dissolution of calcite in the rocks, while 60%--80% is from underground magma.
Published Elegantly modeling Earth's abrupt glacial transitions
(via sciencedaily.com) Original source Milutin Milankovitch hypothesized that the timing of glacial transitions has been controlled by the orbital parameters of the Earth, which suggests that there may be some predictability in the climate, a notoriously complex system. Now researchers propose a new paradigm to simplify the verification of the Milankovitch hypothesis. The new 'deterministic excitation paradigm' combines the physics concepts of relaxation oscillation and excitability to link Earth's orbital parameters and the glacial cycles in a more generic way.
Published Scholars unify color systems using prime numbers
(via sciencedaily.com) Existing color systems, such as RGB and CYMK, are all text-based and require a large range of values to represent different colors, making them difficult to compute and time-consuming to convert. Recently, researchers made a breakthrough by inventing an innovative color system, called 'C235', based on prime numbers, enabling efficient encoding and effective color compression. It can unify existing color systems and has the potential to be applied in various applications, like designing an energy-saving LCD system and colorizing DNA codons.
Published Chromo-encryption method encodes secrets with color
(via sciencedaily.com) In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.
Published Video game playing causes no harm to young children's cognitive abilities, study finds
(via sciencedaily.com) Despite old fears that bad effects follow excessive video game playing or questionable game choices, researchers found those factors mattered little, if any, in children's brain health. The bad news? Video games assumed to be effective learning tools showed no meaningful effects, either.
Published Purchasing loot boxes in video games associated with problem gambling risk, says study
(via sciencedaily.com) Gamers who buy 'loot boxes' are up to two times more likely to gamble, shows new research.
Published Online gaming enhances career prospects and develops soft skills, finds new study
(via sciencedaily.com) Online gaming behavior can encourage gamers to gain a variety of soft skills which could assist them with training to support their career aspirations, according to new research.
Published Microlaser chip adds new dimensions to quantum communication
(via sciencedaily.com) With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.
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 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 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.
