Published Monitoring the well-being of reservoir water through an uncrewed surface vehicle
(via sciencedaily.com) Original source In a recent tragic incident, approximately 100 elephants in Africa perished due to inadequate access to water. The United Nations Environment Programme (UNEP) issues a warning that around 2.5 billion people worldwide could face water scarcity by 2025. In the face of water shortages affecting not only human society but also the entire ecological community due to the climate crisis, it becomes crucial to adopt comprehensive measures for managing water quality and quantity to avert such pressing challenges.
Published Arctic cold snap transforms into a blessing
(via sciencedaily.com) Original source Scientists investigate the influence of Arctic cold air on carbon dioxide uptake of the east sea.
Published Scientists engineer plant microbiome to protect crops against disease
(via sciencedaily.com) Original source Scientists have engineered the microbiome of plants for the first time, boosting the prevalence of 'good' bacteria that protect the plant from disease. The findings could substantially reduce the need for environmentally destructive pesticides.
Published Scientists solve mystery of how predatory bacteria recognizes prey
(via sciencedaily.com) Original source A decades-old mystery of how natural antimicrobial predatory bacteria are able to recognize and kill other bacteria may have been solved, according to new research.
Published Vitamin discovered in rivers may offer hope for salmon suffering from thiamine deficiency disease
(via sciencedaily.com) Original source Researchers have discovered vitamin B1 produced by microbes in rivers, findings that may offer hope for vitamin-deficient salmon populations.
Published Seismic and infrasonic signals used to characterize Nord Stream pipeline events
(via sciencedaily.com) Original source A new study provides further evidence that the Nord Stream seismic signals came from a complex source. The signals lasted longer than would be expected from a single explosive source, the researchers say, and were more like the signals detected from an underwater volcano or a pipeline venting gas.
Published Researchers improve seed nitrogen content by reducing plant chlorophyll levels
(via sciencedaily.com) Original source Chlorophyll plays a pivotal role in photosynthesis, which is why plants have evolved to have high chlorophyll levels in their leaves. However, making this pigment is expensive because plants invest a significant portion of the available nitrogen in both chlorophyll and the special proteins that bind it. As a result, nitrogen is unavailable for other processes. In a new study, researchers reduced the chlorophyll levels in leaves to see if the plant would invest the nitrogen saved into other process that might improve nutritional quality.
Published Microbial awakening restructures high-latitude food webs as permafrost thaws
(via sciencedaily.com) Original source Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.
Published Using electricity, scientists find promising new method of boosting chemical reactions
(via sciencedaily.com) Original source Chemists found a way to use electricity to boost a type of chemical reaction often used in synthesizing new candidates for pharmaceutical drugs. The research is an advance in the field of electrochemistry and shows a path forward to designing and controlling reactions -- and making them more sustainable.
Published Understanding climate mobilities: New study examines perspectives from South Florida practitioners
(via sciencedaily.com) Original source A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.
Published First step towards synthetic CO2 fixation in living cells
(via sciencedaily.com) Original source Three modules forming a new-to-nature CO2 fixation cycle have been successfully implemented in E.coli.
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 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 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 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 Scientists tackle difficult-to-recycle thermoset polymers
(via sciencedaily.com) Original source A team of scientists has got a step closer to making several different types of plastic much easier to recycle, using a method that could be applied to a whole range of difficult-to-recycle polymers, including rubbers, gels and adhesives.
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.
Published Little bacterium may make big impact on rare-earth processing
(via sciencedaily.com) Original source A tiny, hard-working bacterium -- which weighs one-trillionth of a gram -- may soon have a large influence on processing rare earth elements in an eco-friendly way.
Published Researchers invent 'methane cleaner': Could become a permanent fixture in cattle and pig barns
(via sciencedaily.com) Original source In a spectacular new study, researchers have used light and chlorine to eradicate low-concentration methane from air. The result gets us closer to being able to remove greenhouse gases from livestock housing, biogas production plants and wastewater treatment plants to benefit the climate.
