Published Researchers develop more environmentally friendly and cost-effective method for soil remediation
(via sciencedaily.com) Original source Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
Published Researchers warn of unprecedented arsenic release from wildfires
(via sciencedaily.com) Original source The wildfire season of 2023 was the most destructive ever recorded in Canada and a new study suggests the impact was unprecedented. It found that four of the year's wildfires in mine-impacted areas around Yellowknife, Northwest Territories potentially contributed up to half of the arsenic that wildfires emit globally each year.
Published Electric scooter and bike accidents are soaring across the United States
(via sciencedaily.com) Original source In the crowded urban landscape, where small electric vehicles -- primarily scooters and bicycles -- have transformed short distance travel, researchers are reporting a major national surge in accidents tied to 'micromobility.'
Published Best bioenergy crops for sustainable aviation fuels by U.S. region, policy goals
(via sciencedaily.com) Original source Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock -- corn stover, energy sorghum, miscanthus or switchgrass -- performed best in a specific region of the rainfed United States. Their study will help growers and policymakers select the feedstocks most suited to meeting goals like reducing production costs, lowering greenhouse gas emissions and building soil carbon stocks.
Published A window of opportunity for climate change and biodiversity
(via sciencedaily.com) Original source World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle climate change and biodiversity loss, say scientists. Without this, work on tackling either crisis could inadvertently harm progress on the other.
Published Heat-sensitive trees move uphill seeking climate change respite
(via sciencedaily.com) Original source Trees in the Brazilian Atlantic Forest are migrating in search of more favourable temperatures with species in mountain forests moving uphill to escape rising heat caused by climate change.
Published Strategic emission caps key to ammonia industry decarbonization, researchers find
(via sciencedaily.com) Original source New research has revealed critical insights into how strategic emission cap choices can lead to cost-effective, near-100% ammonia industry decarbonization while avoiding issues such as land use constraints and grid congestion.
Published Hot traces in rock
(via sciencedaily.com) Original source Fluids circulating underground change rocks over the course of time. These processes must be taken into account if they are to be used as a climate archive. Researchers have used 380-million-year-old limestones from Hagen-Hohenlimburg to show in detail which climate information is still preserved in the rock.
Published Fruit fly post-mating behavior controlled by male-derived peptide via command neurons, study finds
(via sciencedaily.com) Original source Scientists have succeeded in pinpointing the neurons within a female fruit fly's brain that respond to signals from the male during mating.
Published Children's exposome associated with changes in serum metabolites
(via sciencedaily.com) Original source The combined effect of environmental exposures and unhealthy lifestyle habits can affect children's cardiometabolic health in a way that exceeds their separate effects. A new study shows the benefit of measuring the combined effect of multiple environmental and lifestyle factors.
Published A promising new method uses light to clean up forever chemicals
(via sciencedaily.com) Original source A room-temperature method to decompose perfluoroalkyl substances (PFASs) using visible LED light offers a promising solution for sustainable fluorine recycling and PFAS treatment.
Published Using forest resources strengthens food security
(via sciencedaily.com) Original source Forests can reduce hunger in rural households while also capturing carbon and advancing sustainability goals for low- and middle-income countries, according to new research.
Published Converting captured carbon to fuel: Study assesses what's practical and what's not
(via sciencedaily.com) Original source A new analysis sheds light on major shortfalls of a recently proposed approach to capture CO2 from air and directly convert it to fuel using electricity. The authors also provide a new, more sustainable, alternative.
Published Ecologists discover rare fiddler crab species on Hong Kong coast highlighting the impact of climate change and coastal development
(via sciencedaily.com) Original source Researchers have made an exciting discovery on the Hong Kong coast. They have identified two fiddler crab species: Tubuca dussumieri, previously recorded in old literature but never confirmed in recent times, and Tubuca. coarctata, which has never been seen in Hong Kong. These findings not only confirm the presence of these insular species in Hong Kong but also explore the potential impact of climate change on their distribution.
Published Smell of human stress affects dogs' emotions leading them to make more pessimistic choices
(via sciencedaily.com) Original source Dogs experience emotional contagion from the smell of human stress, leading them to make more 'pessimistic' choices, new research finds. Researchers tested how human stress odors affect dogs' learning and emotional state.
Published Controlling mosquito populations through genetic breeding
(via sciencedaily.com) Original source Researchers have found a new way to identify genetic targets useful for control of mosquito populations, potentially offering an alternative to insecticides. Their study focused on the genetic basis of species incompatibility. They crossed Ae. aegypti, a major global arboviral disease vector, and its sibling species, Ae. mascarensis, from the Indian Ocean. When offspring is crossed back with one parent, about 10 percent of the progeny becomes intersex and is unable to reproduce.
Published Agriculture: Less productive yet more stable pastures
(via sciencedaily.com) Original source Climate change will have a considerable influence on the biodiversity and productivity of meadows and pastures. However, according to the results of the large-scale climate and land use experiment the extent of these changes depends on the land use. Grassland optimized for high yield responds much more sensitively to periods of drought than less intensively used meadows and pastures.
Published Birds need entertainment during avian flu lockdowns
(via sciencedaily.com) Original source Birds need varied activities during avian flu lockdowns, new research shows.
Published Genome study informs restoration of American chestnut tree
(via sciencedaily.com) Original source Researchers use genomes to help restore the American chestnut population and adjust species breeding to the changing climate.
Published Chimpanzees gesture back and forth quickly like in human conversations
(via sciencedaily.com) Original source When people are having a conversation, they rapidly take turns speaking and sometimes even interrupt. Now, researchers who have collected the largest ever dataset of chimpanzee 'conversations' have found that they communicate back and forth using gestures following the same rapid-fire pattern.
