Published To boost supply chains, scientists are looking at ways to recover valuable materials from water
(via sciencedaily.com) Original source Researchers are exploring the different ways of harvesting materials from water.
Published Study finds combustion from gas stoves can raise indoor levels of chemical linked to a higher risk of blood cell cancers
(via sciencedaily.com) Original source About 47 million homes use natural gas or propane-burning cooktops and ovens. Researchers found that cooking with gas stoves can raise indoor levels of the carcinogen benzene above those found in secondhand smoke.
Published How will a warming world impact the Earth's ability to offset our carbon emissions?
(via sciencedaily.com) Original source New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.
Published Massive underwater plateau near Solomon Islands is younger and its eruption was more protracted than previously thought
(via sciencedaily.com) Original source The Ontong Java Plateau, a volcanically-formed underwater plateau located in the Pacific Ocean north of the Solomon Islands, is younger and its eruption was more protracted than previously thought, new research suggests.
Published Scientists discover urea in atmosphere revealing profound consequences for climate
(via sciencedaily.com) Original source Areas of the ocean that are rich in marine life are having a bigger impact on our ecosystems and the climate than previously thought, new research suggests.
Published The life below our feet: Team discovers microbes thriving in groundwater and producing oxygen in the dark
(via sciencedaily.com) Original source A survey of groundwater samples drawn from aquifers beneath more than 80,000 square miles of Canadian prairie reveals ancient groundwaters harbor not only diverse and active microbial communities, but also unexpectedly large numbers of microbial cells. Strikingly, some of these microbes seem to produce 'dark oxygen' (in the absence of sunlight) in such abundance that the oxygen may nourish not only those microbes, but may leak into the environment and support other oxygen-reliant microbes that can't produce it themselves.
Published Preserving forests to protect deep soil from warming
(via sciencedaily.com) Original source An innovative, decade-long experiment in the foothills of California's Sierra Nevada mountains shows carbon stocks buried deep underground are vulnerable to climate change. The findings have implications for mitigating global warming through the natural carbon sinks provided by soil and forests which capture 25% of all carbon emissions.
Published A machine learning approach to freshwater analysis
(via sciencedaily.com) Original source A team of researchers has applied a machine learning model to explore where and to what extent human activities are contributing to the hydrogeochemical changes, such as increases in salinity and alkalinity in U.S. rivers. The group used data from 226 river monitoring sites across the U.S. and built two machine learning models to predict monthly salinity and alkalinity levels at each site.
Published Hotter sand from microplastics could affect sea turtle development
(via sciencedaily.com) Original source New research has found that extreme concentrations of microplastics could increase the temperature of beach sand enough to threaten the development of incubating sea turtles.
Published Scientists investigate the evolution of animal developmental mechanisms, show how some of Earth's earliest animals evolved
(via sciencedaily.com) Original source Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research shows that appearances can be deceiving, and that a common genetic toolkit can be deployed in different ways to drive embryological development to produce very different adult body plans. It is well established that sea anemones, corals, and their jellyfish relatives shared a common ancestor with humans that plied the Earth's ancient oceans over 600 million years ago. A new study from the Gibson Lab, published in Current Biology on June 13, 2023, illuminates the genetic basis for body plan development in the starlet sea anemone, Nematostella vectensis. This new knowledge paints a vivid picture of how some of the earliest animals on earth progressed from egg to embryo to adult.
Published Aluminium-ion batteries with improved storage capacity
(via sciencedaily.com) Original source Scientists develop positive electrode material using an organic redox polymer based on phenothiazine. Aluminium-ion batteries containing this material stored an unprecedented 167 milliampere hours per gram, outperforming batteries using graphite as electrode material. Aluminium-ion batteries are considered a promising alternative to conventional batteries that use scarce raw materials such as lithium.
Published Plant remediation effects on petroleum contamination
(via sciencedaily.com) Original source Initial choices about fertilization and grass seeding could have a long-lasting effect on how plants and their associated microbes break down pollution in petroleum-contaminated soils.
Published A baking soda solution for clean hydrogen storage
(via sciencedaily.com) Original source Scientists investigate the promising properties of a common, Earth-abundant salt.
Published All-electric rideshare fleet could reduce carbon emissions, increase traffic issues
(via sciencedaily.com) Original source Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.
Published Why certain fish are left off the hook
(via sciencedaily.com) Original source A new study found that while a piece of legislation designed to foster the sustainability of marine fisheries is sometimes blamed for being too stringent -- leading to what some politicians call 'underfishing' -- the law is not constraining most fisheries, and there are various other reasons that lead to certain fish species being less fished.
Published When water temperatures change, the molecular motors of cephalopods do too
(via sciencedaily.com) Original source Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.
Published Water molecules define the materials around us
(via sciencedaily.com) Original source A new paper argues that materials like wood, bacteria, and fungi belong to a newly identified class of matter, 'hydration solids.' The new findings emerged from ongoing research into the strange behavior of spores, dormant bacterial cells.
Published Sea cucumbers: The marine delicacy that can deter diabetes
(via sciencedaily.com) Original source They're a marine delicacy loved across Asia, but the humble sea cucumber is also proving to be a key ingredient in preventing diabetes, according to new research.
Published Coral disease tripled in the last 25 years. Three-quarters will likely be diseased by next century
(via sciencedaily.com) Original source Research suggests warming temperatures will see nearly 80 per cent of coral in reefs diseased in the next 80 years.
Published Bubble, bubble, more earthquake trouble? Geoscientists study Alaska's Denali fault
(via sciencedaily.com) Original source Geochemists report findings from collected and analyzed helium and carbon isotopic data from springs along a nearly 250-mile segment of Alaska's Denali Fault. The fault's mantle fluid flow rates, they report, fall in the range observed for the world's other major and active strike-slip faults that form plate boundaries.
