Published Titanium oxide material lets sunlight drive green hydrogen production
(via sciencedaily.com) Original source As part of ongoing efforts to develop materials that could enable alternative energy sources, researchers have produced a titanium oxide nanofilament material that can harness sunlight to unlock the ubiquitous molecule's potential as a fuel source.
Published Supercomputer used to simulate winds that cause clear air turbulence
(via sciencedaily.com) Using Japan's most powerful supercomputer, researchers reproduced cases of clear air turbulence around Tokyo. They simulated the fine vortices responsible for this dangerous phenomenon. The usefulness of the simulation in predicting turbulence was confirmed by comparing simulation data with data from aircraft recordings. This research should improve the forecasting of turbulence.
Published A better understanding of turbulence
(via sciencedaily.com) Experiments at a unique wind tunnel show that laws formulated more than 80 years ago and their extensions only incompletely explain turbulent flows.
Published Unused renewable energy an option for powering NFT trade
(via sciencedaily.com) Original source Unused solar, wind, and hydroelectric power in the U.S. could support the exponential growth of transactions involving non-fungible tokens (NFTs), researchers have found.
Published Organic electronics: Sustainability during the entire lifecycle
(via sciencedaily.com) Original source Organic electronics can make a decisive contribution to decarbonization and, at the same time, help to cut the consumption of rare and valuable raw materials. To do so, it is not only necessary to further develop manufacturing processes, but also to devise technical solutions for recycling as early on as the laboratory phase. Materials scientists are now promoting this circular strategy.
Published Public support hydrogen and biofuels to decarbonize global shipping
(via sciencedaily.com) Original source New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen. The study also found that nuclear was preferred to the heavy fuel oil (HFO) currently used in the global shipping industry, although both were perceived negatively. Ammonia had the least public support.
Published Marine heat waves caused mass seabird die-offs, beach surveys show
(via sciencedaily.com) Original source New research uses data collected by coastal residents along beaches from central California to Alaska to understand how seabirds have fared in recent decades. The paper shows that persistent marine heat waves lead to massive seabird die-offs months later.
Published Three things to know: Climate change's impact on extreme-weather events
(via sciencedaily.com) Original source Researchers found that the effects of climate change on the intensity, frequency, and duration of extreme weather events, like wildfires, could lead to massive increases in all three.
Published Birds raise fewer young when spring arrives earlier in a warming world
(via sciencedaily.com) Original source A new study of North American songbirds finds that birds can't keep up with the earlier arrival of spring caused by climate change. As a result, they're raising fewer young. By the end of the 21st century, climate change will cause springlike weather to begin 25 days earlier, but birds will only breed about seven days earlier. That change could lead to an average reduction of 12% in breeding productivity for songbird species.
Published New study reveals abrupt shift in tropical Pacific climate during Little Ice Age
(via sciencedaily.com) Original source An El Niño event has officially begun. The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years will shape weather across the planet for the next year or more and give rise to various climatic extremes. El Niño-like conditions can also occur on longer time scales of decades or centuries. This has been shown to have occurred in the recent past.
Published Scientists propose new strategy for modern sails to help shipping sector meet its carbon reduction goals
(via sciencedaily.com) Original source Researchers have identified a strategy that can offset the random and unpredictable nature of weather conditions that threaten carbon emission reduction efforts in the shipping sector.
Published Freely available risk model for hurricanes, tropical cyclones
(via sciencedaily.com) Original source As human-driven climate change amplifies natural disasters, hurricanes and typhoons stand to increase in intensity. Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the completion of an open-source model that stands to help countries with high tropical cyclone risks better calculate just how much those storms will impact their people and their economies.
Published Wind farm noise exposure doesn't wake people up from their slumber more than road traffic noise
(via sciencedaily.com) Original source Short exposure to wind farm and road traffic noise triggers a small increase in people waking from their slumber that can fragment their sleep patterns, according to new research. But importantly, the new study also shows that wind farm noise isn't more disruptive to sleep than road traffic, which was a little more disruptive at the loudest audio level but not at more common levels. Sleep researchers have studied the impact of exposure to wind farm noise during sleep in three new scientific publications to better understand its impact.
Published New nationwide modeling points to widespread racial disparities in urban heat stress
(via sciencedaily.com) Original source Using a combination of satellite data and modeling to study the temperatures and humidity people might feel in urban areas, researchers have pinpointed who in the U.S. is most vulnerable to heat stress.
Published City buildings could blow air taxi future off course
(via sciencedaily.com) Original source Air taxis may be coming to our cities in the near future, but a new study warns regulations will need to address dangerous wind gusts around city buildings and other urban infrastructure.
Published Perovskite solar cells set new record for power conversion efficiency
(via sciencedaily.com) Original source Perovskite solar cells have attained now attained the extremely high efficiency rate of 24.35% with an active area of 1 cm2. This ground-breaking achievement in maximizing power generation from next-generation renewable energy sources will be crucial to securing the world's energy future.
Published Flooding tackled by helping citizens take action
(via sciencedaily.com) Original source Scientists have developed a new method that empowers citizens to identify solutions to climate change threats.
Published Wildfire smoke downwind affects health, wealth, mortality
(via sciencedaily.com) Original source Smoke particulates from wildfires could cause between 4,000 and 9,000 premature deaths and cost between $36 to $82 billion per year in the United States, according to new research.
Published A Tongan volcano plume produced the most intense lightning rates ever detected
(via sciencedaily.com) Original source New research showed that the plume emitted by the Hunga Volcano eruption in 2022 created the highest lightning flash rates ever recorded on Earth, more than any storm ever documented.
Published Clean, sustainable fuels made 'from thin air' and plastic waste
(via sciencedaily.com) Original source Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the Sun.
