Published Next-generation sustainable electronics are doped with air
(via sciencedaily.com) Original source Semiconductors are the foundation of all modern electronics. Now, researchers have developed a new method where organic semiconductors can become more conductive with the help of air as a dopant. The study is a significant step towards future cheap and sustainable organic semiconductors.
Published Scientists generate heat over 1,000 degrees Celsius with solar power instead of fossil fuel
(via sciencedaily.com) Original source Instead of burning fossil fuels to smelt steel and cook cement, researchers in Switzerland want to use heat from the sun. The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000 C (1,832 F), demonstrating the method's potential role in providing clean energy for carbon-intensive industries.
Published The case for sharing carbon storage risk
(via sciencedaily.com) Original source Even the most optimistic projections for the rapid build-out of solar, wind, and other low-carbon resources acknowledge that coal, natural gas, and other fossil fuels will dominate the world's energy mix for decades to come. If the vast greenhouse gas emissions from burning these fossil fuels continue to enter the planet's atmosphere, global warming will not be limited to sustainable levels. The capture and geologic sequestration of carbon emissions (CCS) offer a promising solution to the world's carbon conundrum.
Published Meet the new insect killing Utah's fir trees
(via sciencedaily.com) Original source The balsam woolly adelgid, a tiny nonnative flightless insect, is spreading across the American West killing subalpine fir in northern Utah's recreation-heavy mountain ranges and canyons. Rsearchers document a close association between the pest's spread and warming temperatures.
Published Petroleum, chlorine mix could yield harmful byproducts
(via sciencedaily.com) Original source A new study shows that chlorine mixed with petroleum in water can potentially produce inadvertent byproducts harmful to human health.
Published 90% of Floridians believe climate change is happening
(via sciencedaily.com) Original source The latest 'Florida Climate Resilience Survey' found that 90% of Floridians believe that climate change is happening. Belief in human-caused climate change has surged among Florida Independents while slipping among Republicans in the state since last fall. But despite these changes, the survey found enduring support among Floridians for increased government action to address the consequences of a warming planet. The survey found 68% of all respondents want state government to do more and 69% want the federal government to do more to address climate change.
Published Transforming waste carbon dioxide into high-value chemicals with a cost reduction of about 30%
(via sciencedaily.com) Original source A team of scientists has developed a novel technique to convert carbon dioxide (CO2) from treated flue gas directly into high-value chemicals and fuels. This innovation sidesteps the conventional approach of using high-purity CO2 for electrochemical reduction processes, achieving significant cost savings of about 30%.
Published Avocado pruning residues used to produce more sustainable food packaging
(via sciencedaily.com) Original source A prototype of a more durable material increases the biodegradability of food packaging, partially replacing its bioplastic with cellulose fibers extracted from the branches and leaves of the avocado tree.
Published How wildfires change soil chemistry
(via sciencedaily.com) Original source Severe wildfires can drive chemical changes in soil that affect ecosystem recovery and risks to human health. A new study finds broader surveillance and modeling of these changes could inform strategies for protecting lives, property and natural resources, and managing wildlife.
Published WASP-193b, a giant planet with a density similar to that of cotton candy
(via sciencedaily.com) Original source Astronomers have just discovered WASP-193b, an extraordinarily low-density giant planet orbiting a distant Sun-like star.
Published Young whale's journey highlights threats facing ocean animals
(via sciencedaily.com) Original source A young whale's journey across the Mediterranean highlights the many threats facing ocean animals, researchers say.
Published Researchers discover the universe's oldest stars in our own galactic backyard
(via sciencedaily.com) Original source Astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way's 'halo' -- the cloud of stars that envelopes the entire main galactic disk -- and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape.
Published 2023 was the hottest summer in two thousand years
(via sciencedaily.com) Original source Researchers have found that 2023 was the hottest summer in the Northern Hemisphere in the past two thousand years, almost four degrees warmer than the coldest summer during the same period.
Published Today's world: Fastest rate of carbon dioxide rise over the last 50,000 years
(via sciencedaily.com) Original source Today's rate of atmospheric carbon dioxide increase is 10 times faster than at any other point in the past 50,000 years, researchers have found through a detailed chemical analysis of ancient Antarctic ice.
Published Island birds more adaptable than previously thought
(via sciencedaily.com) Original source The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.
Published The price tag of phasing-out coal
(via sciencedaily.com) Original source Coal phase-out is necessary to solve climate change, but can have negative impacts on workers and local communities dependent on coal for their livelihoods. Researchers have studied government plans for coal phase-out around the world and discovered that more than half of such plans include monetary compensation to affected parties. This planned compensation globally amounts to USD 200 billion, but it excludes China and India, the two largest users of coal that currently do not have phase-out plans. The study shows that if China and India decide to phase out coal as fast as needed to reach the Paris climate targets and pay similar compensation, it would cost upwards of USD 2 trillion.
Published Scientists unlock key to breeding 'carbon gobbling' plants with a major appetite
(via sciencedaily.com) Original source The discovery of how a critical enzyme 'hidden in nature's blueprint' works sheds new light on how cells control key processes in carbon fixation, a process fundamental for life on Earth. The discovery could help engineer climate resilient crops capable of sucking carbon dioxide from the atmosphere more efficiently, helping to produce more food in the process.
Published US Navy Growler jet noise over Whidbey Island could impact 74,000 people's health
(via sciencedaily.com) Original source As often as four days a week, Boeing EA-18G Growler electronic attack aircraft based at Naval Air Station Whidbey Island fly loops overhead as pilots practice touch-and-go landings. The noise is immense. New research shows that the noise isn't just disruptive -- it presents a substantial risk to public health.
Published ONe novae stellar explosion may be source of our phosphorus
(via sciencedaily.com) Original source Astronomers have proposed a new theory to explain the origin of phosphorus, one of the elements important for life on Earth. The theory suggests a type of stellar explosion known as ONe novae as a major source of phosphorus.
Published New light shed on carboxysomes in key discovery that could boost photosynthesis
(via sciencedaily.com) Original source A research team has discovered how carboxysomes, carbon-fixing structures found in some bacteria and algae, work. The breakthrough could help scientists redesign and repurpose the structures to enable plants to convert sunlight into more energy, paving the way for improved photosynthesis efficiency, potentially increasing the global food supply and mitigating global warming.
