Published Effect of aerosol particles on clouds and the climate captured better
(via sciencedaily.com) Original source Global measurements and model calculations show that the complex relationship between the chemistry and climate impact of aerosol particles can be successfully captured by a simple formula.
Published Protect delicate polar ecosystems by mapping biodiversity
(via sciencedaily.com) Original source Concerted action is required to mitigate the impact of warming on polar ecosystems and sustainably manage these unique habitats.
Published New percussion method to detect pipeline elbow erosion
(via sciencedaily.com) Original source An engineering research team is pioneering a new method, based on percussion, to detect pipeline elbow erosion to prevent economic losses, environmental pollution and other safety issues.
Published Massive 2022 eruption reduced ozone layer levels
(via sciencedaily.com) Original source The Hunga Tonga-Hunga Ha'apai volcano changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to unprecedented losses in the ozone layer of up to 7% over large areas of the Southern Hemisphere.
Published Innovative aquaculture system turns waste wood into nutritious seafood
(via sciencedaily.com) Original source Innovative aquaculture system turns waste wood into nutritious seafood. Researchers hoping to rebrand a marine pest as a nutritious food have developed the world's first system of farming shipworms, which they have renamed 'Naked Clams'.
Published Microbiome development: Bacteria lay the foundations for their descendants
(via sciencedaily.com) Original source The microbiome (the symbiotic community of microbial organisms of a host) is of existential importance for the functioning of every plant and animal, including human beings. A research team has now used the example of the sea anemone Nematostella vectenis to investigate how the microbiome develops together with the host. The researchers describe that the bacterial community is primarily controlled by the host organism during the early stages of life, while bacteria-bacteria interactions play the lead role in subsequent development.
Published Researchers develop comprehensive genetic map for bison, discover gene responsible for albinism
(via sciencedaily.com) Original source Researchers have determined the gene mutation responsible for an observable trait in bison -- albinism.
Published New research suggests plants might be able to absorb more CO2 from human activities than previously expected
(via sciencedaily.com) Original source New research paints an uncharacteristically upbeat picture for the planet. This is because more realistic ecological modelling suggests the world's plants may be able to take up more atmospheric CO2 from human activities than previously predicted.
Published Idai vs. Impalas: New study shows in real-time what helps mammals survive a natural disaster
(via sciencedaily.com) Original source After a massive cyclone transformed the ecosystem of Gorongosa National Park, researchers studied the immediate and knock-on impacts to garner lessons for wildlife managers around the world.
Published Putting an end to plastic separation anxiety
(via sciencedaily.com) Original source Bio-based plastics often end up in recycling streams because they look and feel like conventional plastic, but the contamination of these compostable products makes it much harder to generate functional material out of recycled plastic. Scientists have now developed a biology-driven process to convert these mixtures into a new biodegradable material that can be used to make fresh products. The scientists believe the process could also enable a new field of biomanufacturing wherein valuable chemicals and even medicines are made from microbes feeding off of plastic waste.
Published Scientists have solved the damselfly color mystery
(via sciencedaily.com) Original source For over 20 years, a research team has studied the common bluetail damselfly. Females occur in three different color forms -- one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic color variation that is shared between several species arose through changes in a specific genomic region at least five million years ago.
Published Shedding light on unique conduction mechanisms in a new type of perovskite oxide
(via sciencedaily.com) Original source The remarkable proton and oxide-ion (dual-ion) conductivities of hexagonal perovskite-related oxide Ba7Nb3.8Mo1.2O20.1 are promising for next-generation electrochemical devices. The unique ion-transport mechanisms they unveiled will hopefully pave the way for better dual-ion conductors, which could play an essential role in tomorrow's clean energy technologies.
Published Like the phoenix, Australia's giant birds of prey rise again from limestone caves
(via sciencedaily.com) Original source Australia's only vulture, and a fearsome extinct eagle, are among the earliest recorded birds of prey from the Pleistocene period more than 50,000 years ago -- and now researchers are bringing them to 'life' again. Along with new scientific information, a bold new pictorial reconstruction of a newly named eagle and the only known Australian vulture will be unveiled at the World Heritage-listed Naracoorte Caves in South Australia's Limestone Coast this month.
Published Nature photographers posting to social media help with protecting biodiversity
(via sciencedaily.com) Original source Nature photographers posting to social media are helping improve biodiversity conservation mapping in South Asia, and the method could go global.
Published Research in Lake Superior reveals how sulfur might have cycled in Earth's ancient oceans
(via sciencedaily.com) Original source A scientists has sulfur on her mind. The yellow element is a vital macronutrient, and she's trying to understand how it cycles through the environment. Specifically, she's curious about the sulfur cycle in Earth's ancient ocean, some 3 billion years ago.
Published Pushing the boundaries of eco-friendly chemical production
(via sciencedaily.com) Original source A team of pioneering researchers has made a significant leap forward in the complex world of molecular chemistry. Their focus? Azaarenes, unique molecular puzzle pieces crucial to many everyday products, from eco-friendly agrochemicals to essential medicines. The team developed an innovative way to modify these molecules using light-powered enzymes -- a groundbreaking discovery that holds promise for new industrially relevant chemical reactions and sustainable energy solutions.
Published Temperature variability reduces nesting success
(via sciencedaily.com) Original source Many songbirds are nesting earlier in spring because of warmer temperatures brought about by climate change. But the shift brings another danger that is especially deadly for nestlings: greater exposure to temperature variability in the form of cold snaps and heat waves.
Published Birds set foot near South Pole in Early Cretaceous, Australian tracks show
(via sciencedaily.com) Original source The discovery of 27 avian footprints on the southern Australia coast -- dating back to the Early Cretaceous when Australia was still connected to Antarctica -- opens another window onto early avian evolution and possible migratory behavior.
Published More than meows: How bacteria help cats communicate
(via sciencedaily.com) Original source Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study shows how domestic cats send signals to each other using odors derived from families of bacteria living in their anal glands.
Published Forget social distancing: House finches become more social when sick
(via sciencedaily.com) Original source Social distancing when sick has become second nature to many of us in the past few years, but some sick animals appear to take a different approach. A new study of house finches uncovered a surprising result. Unlike other social animals who passively or actively isolate themselves when sick, this gregarious backyard bird species gravitates toward healthy flock mates when they are sick, even more so than healthy birds do.
