Published Using sound to test devices, control qubits
(via sciencedaily.com) Original source Researchers have developed a system that uses atomic vacancies in silicon carbide to measure the stability and quality of acoustic resonators. What's more, these vacancies could also be used for acoustically-controlled quantum information processing, providing a new way to manipulate quantum states embedded in this commonly-used material.
Published Rider on the storm: Shearwater seabird catches an 11 hour ride over 1,000 miles in a typhoon
(via sciencedaily.com) Original source New research suggests that increasingly severe weather driven by climate change may push oceangoing seabirds to their limits.
Published UK air pollution regulations will reduce deaths, but do little to protect ecosystems
(via sciencedaily.com) Original source Existing air pollution regulations will reduce thousands of premature adult deaths in the UK, but even the most effective technically feasible actions, which will save thousands more lives, will do little to protect the country's sensitive ecosystems, find researchers.
Published Single model predicts trends in employment, microbiomes, forests
(via sciencedaily.com) Original source Researchers report that a single, simplified model can predict population fluctuations in three unrelated realms: urban employment, human gut microbiomes and tropical forests. The model will help economists, ecologists, public health authorities and others predict and respond to variability in multiple domains.
Published Achieving large and uniform particle sizes
(via sciencedaily.com) Original source Dispersions of polymer particles in a liquid phase (latexes) have many important applications in coatings technology, medical imaging, and cell biology. A team of researchers has now developed a method to produce stable polystyrene dispersions with unprecedentedly large, and uniform, particle sizes. Narrow size distributions are essential in many advanced technologies, but were previously difficult to produce photochemically.
Published Report warns about risk tipping points with irreversible impacts on people and planet
(via sciencedaily.com) Original source A new report finds that drastic changes are approaching if risks to our fundamental socioecological systems are not addressed. The Interconnected Disaster Risks Report 2023 warns of six risk tipping points ahead of us: Accelerating extinctions; Groundwater depletion; Mountain glaciers melting; Space debris; Unbearable heat; and an Uninsurable future.
Published A sustainable future is based on a learning society
(via sciencedaily.com) Original source A holistic transformation is needed for the planet to accommodate people's pursuit of well-being. A new study explores a Theory of Planetary Social Pedagogy as a driver of a transformative process based on a learning society.
Published Diapers can be recycled 200 times faster with light
(via sciencedaily.com) Original source More than 100,000 tons of diapers are disposed of annually in Germany. Vast amounts of valuable resources, such as diaper liners, end up in the trash. The liners consist of special polymers, so-called superabsorbers. Researchers have now succeeded in considerably improving their complex recycling process. They use UV radiation to degrade the chemical chains that keep the polymers together. No chemicals are needed. Recycling at room temperature is 200 times faster than conventional recycling. The recycled polymers can then be processed to new adhesives and dyes.
Published New study finds hidden trees across Europe: A billion tons of biomass is overlooked today
(via sciencedaily.com) Original source Through satellite imaging a new AI driven mapping of biomass and CO2 storage shows that a huge number of trees are overlooked in Europe's urban, rural, and agricultural areas. Across Europe, researchers have discovered a billion tons of hidden biomass.
Published Pig welfare outweighs climate concerns for consumers
(via sciencedaily.com) Original source Consumers would rather pay more for higher-welfare pork than for pork with a reduced climate footprint, according to a new study.
Published Sunflower extract fights fungi to keep blueberries fresh
(via sciencedaily.com) Original source Opening a clamshell of berries and seeing them coated in fuzzy mold is a downer. And it's no small problem. Gray mold and other fungi, which cause fruit to rot, lead to significant economic losses and food waste. Now, researchers report that compounds from sunflower crop waste prevented rotting in blueberries. They suggest the food industry could use these natural compounds to protect against post-harvest diseases.
Published Adapting to climate change: Individuals take action while governments plan
(via sciencedaily.com) Original source While governments may take the lead in planning and financing climate change adaptation measures, such as incentivizing green infrastructure, individuals currently are most often the ones implementing actions to adapt to climate change, according to new research.
Published Bitcoin mining has 'very worrying' impacts on land and water, not only carbon
(via sciencedaily.com) Original source As bitcoin and other cryptocurrencies have grown in market share, they've been criticized for their heavy carbon footprint: Cryptocurrency mining is an energy-intensive endeavor. Mining has massive water and land footprints as well, according to a new study that is the first to detail country-by-country environmental impacts of bitcoin mining.
Published Adding crushed rock to farmland pulls carbon out of the air
(via sciencedaily.com) Original source Adding crushed volcanic rock to farmland can pull carbon dioxide out of the air. In a field test, scientists found that the process works even in dry climates.
Published Raining cats and dogs: Global precipitation patterns a driver for animal diversity
(via sciencedaily.com) Original source A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.
Published Climate report: 'Uncharted territory' imperils life on Earth
(via sciencedaily.com) Original source An international coalition of climate scientists says that the Earth's vital signs have worsened beyond anything humans have yet seen, to the point that life on the planet is imperiled.
Published Scientists develop new method to create stable, efficient next-gen solar cells
(via sciencedaily.com) Original source Next-generation solar materials are cheaper and more sustainable to produce than traditional silicon solar cells, but hurdles remain in making the devices durable enough to withstand real-world conditions. A new technique could simplify the development of efficient and stable perovskite solar cells, named for their unique crystalline structure that excels at absorbing visible light.
Published Getting maximum calories in shortest time is the priority for bumblebees
(via sciencedaily.com) Original source Research has found that bumblebees make foraging choices to collect the most sugar from flowers in the shortest time -- even if that means using more energy in the process -- to provide an immediate energy boost for the colony.
Published Solar farms in space are possible
(via sciencedaily.com) Original source It's viable to produce low-cost, lightweight solar panels that can generate energy in space, according to new research.
Published Certain per- and polyfluoroalkyl 'forever chemicals' identified as potential risk factor for thyroid cancer
(via sciencedaily.com) Original source Researchers have discovered a link between certain per- and polyfluoroalkyl substances (PFAS) and an increased risk for thyroid cancer.
