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 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 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 Research offers a reason why diversity in plant species causes higher farming yield, solving 'a bit of a mystery'
(via sciencedaily.com) Original source A study appearing in Nature Communications based on field and greenhouse experiments at the University of Kansas shows how a boost in agricultural yield comes from planting diverse crops rather than just one plant species: Soil pathogens harmful to plants have a harder time thriving. While crop rotation and other farming and gardening practices long have reflected benefits of a mix of plants, the new research puts hard data to one important mechanism underpinning the observation: the numbers of microorganisms in the soil that eat plants.
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.
Published Some coral species might be more resilient to climate change than previously thought
(via sciencedaily.com) Original source Some coral species can be resilient to marine heat waves by 'remembering' how they lived through previous ones, research suggests.
Published Hotter weather caused by climate change could mean more mosquitoesv
(via sciencedaily.com) Original source Research along James River in Richmond suggests that climate change could shorten window for predators to prey on larvae.
Published 15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems
(via sciencedaily.com) Original source Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.
Published Ecosystem benefits to humanity expected to decline by 9% by 2100
(via sciencedaily.com) Original source A new study of natural capital finds nature's benefits to humanity are expected to decline as climate change shifts ecosystems across borders.
Published Coral atoll islands may outpace sea-level rise with local ecological restoration, scientists say
(via sciencedaily.com) Original source Ecological restoration may save coral atoll islands from the rising seas of climate change, according to an international team of scientists, conservationists, and an indigenous leader.
