Published Global warming intensifies typhoon-induced extreme precipitation over East Asia
(via sciencedaily.com) Original source Scientists use a 3km high-resolution climate model to reveal expanded extreme rainfall from typhoons.
Published Unraveling the mysteries of fog in complex terrain
(via sciencedaily.com) Original source While fog presents a major hazard to transportation safety, meteorologists have yet to figure out how to forecast it with the precision they have achieved for precipitation, wind and other stormy events. This is because the physical processes resulting in fog formation are extremely complex, Now researchers report their findings from an intensive study centered on a northern Utah basin and conceived to investigate the life cycle of cold fog in mountain valleys.
Published In coastal communities, sea level rise may leave some isolated
(via sciencedaily.com) Original source Amid the threat of dramatic sea level rise, coastal communities face unprecedented dangers, but a new study reveals that as flooding intensifies, disadvantaged populations will be the ones to experience some of the most severe burdens of climate change.
Published Western Cascades landscapes in Oregon historically burned more often than previously thought
(via sciencedaily.com) Original source Forests on the west slope of Oregon's Cascade Range experienced fire much more often between 1500 and 1895 than had been previously thought.
Published Electronic 'soil' enhances crop growth
(via sciencedaily.com) Original source Barley seedlings grow on average 50% more when their root system is stimulated electrically through a new cultivation substrate. Researchers have now developed an electrically conductive 'soil' for soil-less cultivation, known as hydroponics.
Published New material allows for better hydrogen-based batteries and fuel cells
(via sciencedaily.com) Original source Researchers have developed a solid electrolyte for transporting hydride ions at room temperature. This breakthrough means that the full advantages of hydrogen-based solid-state batteries and fuel cells can be had without the need for constant hydration. This will reduce their complexity and cost, which is essential for advancing towards a practical hydrogen-based energy economy.
Published How technology and economics can help save endangered species
(via sciencedaily.com) Original source A lot has changed in the world since the Endangered Species Act (ESA) was enacted 50 years ago in December 1973. Experts are now discuss how the ESA has evolved and what its future might hold.
Published Novel catalyst system for CO2 conversion
(via sciencedaily.com) Original source Researchers are constantly pushing the limits of technology by breaking new ground in CO2 conversion. Their goal is to turn the harmful greenhouse gas into a valuable resource. A novel catalyst system could help reach that goal.
Published Insects already had a variety of defense strategies in the Cretaceous
(via sciencedaily.com) Original source Analyses of amber show that insect larvae were already using a wide variety of tactics to protect themselves from predators 100 million years ago.
Published How national policies affect forests in border regions
(via sciencedaily.com) Original source How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.
Published Unveiling ancient secrets: 3D preservation of trilobite soft tissues sheds light on convergent evolution of defensive enrollment
(via sciencedaily.com) Original source Researchers describe unusual trilobite fossils prepared as thin sections showing the 3D soft tissues during enrollment. The study reveals the soft undersides of enrolled trilobites and the evolutionary mechanism that allows arthropods to enroll their bodies for protection from predators and adverse environmental conditions.
Published Finding new ways to adapt to a growing weather threat
(via sciencedaily.com) Original source Research reveals a steady increase in the number of people at risk from tropical cyclones and the number of days per year these potentially catastrophic storms threaten health and livelihoods. The findings could help relief agencies, development banks, and other organizations plan more effective strategies for mitigating extreme weather impacts.
Published Scientists uncover link between the ocean's weather and global climate
(via sciencedaily.com) Original source Scientists outline the first direct evidence linking seemingly random weather systems in the ocean with climate on a global scale. The team's work creates a promising framework for better understanding the climate system.
Published Multitasking microbes: Scientists engineer bacteria to make two valuable products from plant fiber
(via sciencedaily.com) Original source Researchers have engineered bacteria that can produce two chemical products at the same time from underutilized plant fiber. And unlike humans, these multitasking microbes can do both things equally well. The discovery could help make biofuels more sustainable and commercially viable.
Published Reduced air pollution during pandemic points to way to preserve Himalayan glaciers
(via sciencedaily.com) Original source Reducing air pollution to levels similar to those during the coronavirus pandemic could protect the glaciers in the Himalayas and prevent them from disappearing by the end of the century. This is the conclusion reached by an international research team analyzing the situation during the COVID-19 lockdown in 2020.
Published World's smallest 'fanged' frogs found in Indonesia
(via sciencedaily.com) Original source Researchers have identified a species of frog new to science. The Indonesian amphibian is the size of a quarter, unlike its two-pound cousins, and has tiny fangs. Nearly uniquely among amphibians, they lay their eggs on the leaves of trees, and the males guard and tend to the nests.
Published Scientists provide recipe to halve pollution from food production
(via sciencedaily.com) Original source A major report has put forward solutions to halve nitrogen pollution from agriculture and the food system in Europe, including reducing meat and dairy consumption, fertilizer use and food waste. Inefficiencies in farms, retail and wastewater practices mean that the nitrogen use efficiency of the food system in Europe is only 18%, leaving most of the remainder leaking into air, water and soils. The new report, Appetite for Change, has been produced by a group of researchers coordinated by the UK Centre for Ecology & Hydrology (UKCEH), the European Commission, Copenhagen Business School and the National Institute for Public Health and the Environment (RIVM) of The Netherlands.
Published Low economic growth can help keep climate change within the 1.5 °C threshold
(via sciencedaily.com) Original source A new study shows that economic growth rates make a big difference when it comes to prospects for limiting global warming to 1.5 °C, as per the Paris Agreement. A recent study shows that pursuing higher economic growth may jeopardize the Paris goals and leave no viable pathways for humanity to stabilize the climate. On the contrary, slower growth rates make it more feasible to achieve the Paris goals.
Published Mysterious fruit shown to be the oldest known fossils of the Frankincense and Myrrh family
(via sciencedaily.com) Original source Early in the 1970s, paleontologists discovered strange fossilized fruits between hardened rock from one of the largest volcanic eruptions in Earth's history. The identity of these fossils remained elusive for the next several decades. Using CT scanning, scientists have now determined they are the oldest fossils from species in the Frankincense and Myrrh family.
Published Genetic sequencing uncovers unexpected source of pathogens in floodwaters
(via sciencedaily.com) Original source Researchers report that local rivers and streams were the source of the Salmonella enterica contamination along coastal North Carolina after Hurricane Florence in 2018 -- not the previously suspected high number of pig farms in the region.
