Published Naturally regrowing forests are helping to protect the remaining old forests in the Amazon
(via sciencedaily.com) Original source Secondary forests that have regrown naturally on land abandoned from agriculture are important in counteracting the effects of forest fragmentation across the Amazon basin, according to new findings.
Published Diverse forests hold huge carbon potential, as long as we cut emissions
(via sciencedaily.com) Original source New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. In brief: Forests have the potential to capture 226 Gigatonnes (Gt) of carbon in areas where they would naturally exist. This forest potential can only be achieved alongside emissions cuts. Sixty-one percent of the forest potential can be achieved by protecting existing forests and allowing them to regrow to maturity. Thirty-nine percent can be achieved by reconnecting fragmented landscapes through community-driven ecosystem restoration and management. A natural diversity of species is needed to maximize the forest carbon potential.
Published Solar-powered device produces clean water and clean fuel at the same time
(via sciencedaily.com) Original source A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been developed by researchers.
Published Yucatán's underwater caves host diverse microbial communities
(via sciencedaily.com) Original source With help from an experienced underwater cave-diving team, researchers have constructed the most complete map to date of the microbial communities living in the submerged labyrinths beneath Mexico's Yucatán Peninsula. Researchers found the cave system's microbiome is distinct from the nearby sea, and microbial communities vary between cave systems forming distinct 'neighborhoods.'
Published Low-intensity fires reduce wildfire risk by 60%
(via sciencedaily.com) Original source High-intensity, often catastrophic, wildfires have become increasingly frequent across the Western U.S. Researchers quantified the value of managed low-intensity burning to dramatically reduce the risk of such fires for years at a time.
Published quantum mechanics: Unlocking the secrets of spin with high-harmonic probes
(via sciencedaily.com) Original source Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ballet is the cornerstone of magnetic phenomena, and it's these spins that a team of researchers has learned to control with remarkable precision, potentially redefining the future of electronics and data storage.
Published New work sheds light on inner working of cells
(via sciencedaily.com) Original source New research provides a deeper understanding of the way components within cells are interconnected. Through cellular visualization using SRS microscopy, researchers have addressed the challenge of attaining clear images of individual processes.
Published Scientists found hundreds of toxic chemicals in recycled plastics
(via sciencedaily.com) Original source When scientists examined pellets from recycled plastic collected in 13 countries they found hundreds of toxic chemicals, including pesticides and pharmaceuticals. Because of this, the scientists judge recycled plastics unfit for most purposes and a hinder in the attempts to create a circular economy.
Published Chemists image basic blocks of synthetic polymers
(via sciencedaily.com) Original source Researchers have developed a new method to image polymerization catalysis reactions one monomer at a time.
Published New way to count microbes speeds research, cuts waste, could lead to new antibiotics
(via sciencedaily.com) Original source Researchers have developed a new way of counting microorganisms that works as much as 36 times faster than conventional methods, cuts plastic use more than 15-fold and substantially decreases the cost and carbon footprint of biomedical research. The technique could revolutionize the way microbiology experiments are conducted, allowing researchers to test potential new antibiotics in a fraction of the time.
Published Scientists use quantum biology, AI to sharpen genome editing tool
(via sciencedaily.com) Original source Scientists used their expertise in quantum biology, artificial intelligence and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.
Published Bacteria-virus arms race provides rare window into rapid and complex evolution
(via sciencedaily.com) Original source Rather than a slow, gradual process as Darwin envisioned, biologists can now see how evolutionary changes unfold on much more accelerated timescales. Using an accelerated arms race between bacteria and viruses, researchers are documenting rapid evolutionary processes in simple laboratory flasks in only three weeks.
Published Barnacle bends shape to fend off warm-water sea snails on the move
(via sciencedaily.com) Original source Some barnacles are 'morphing' to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change.
Published Plastics treaty must tackle problem at source
(via sciencedaily.com) Original source The new Global Plastics Treaty must tackle the problem at source, researchers say. They say the treaty must prioritize 'upstream' issues: cutting total production and consumption of plastics, phasing out hazardous chemicals and tackling fossil fuel subsidies.
Published Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage
(via sciencedaily.com) Original source Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
Published Liquid metals shake up century-old chemical engineering processes
(via sciencedaily.com) Original source Liquid metals could be the long-awaited solution to 'greening' the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineering processes harking back to the early 20th century.
Published Zooplankton in ocean and freshwater are rapidly escalating the global environmental threat of plastics
(via sciencedaily.com) Original source A collaborative research team has recently revealed that rotifers, a kind of microscopic zooplankton common in both fresh and ocean water around the world, are able to chew apart microplastics, breaking them down into even smaller, and potentially more dangerous, nanoplastics -- or particles smaller than one micron. Each rotifer can create between 348,000 -- 366,000 per day, leading to uncountable swarms of nanoparticles in our environment.
Published A fifth of European Red List flora and fauna species may be at risk of extinction
(via sciencedaily.com) Original source A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.
Published Feral horses and peatland carbon emissions
(via sciencedaily.com) Original source A ground-breaking new study has found carbon emissions from Australian alpine peatlands to be much higher in areas disturbed by feral horses.
Published Southern Alaska's national forests key to meeting climate, conservation goals
(via sciencedaily.com) Original source Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
