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 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 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 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 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 New study reveals huge potential for future waves of invasive species
(via sciencedaily.com) Original source Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.
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 Climate change effects hit marine ecosystems in multiple waves, according to marine ecologists
(via sciencedaily.com) Original source A new approach to examining the effects of climate change on marine ecosystems may provide a more accurate understanding of climate change responses -- and predictions for future consequences -- according to a new article. The paper highlights the interplay between the trend of climate warming and the fluctuations in local temperature. These two properties cause atypically warm events such as marine heatwaves to occur with increasing frequency and magnitude.
Published Microbes could help reduce the need for chemical fertilizers
(via sciencedaily.com) Original source A new metal-organic coating protects bacterial cells from damage without impeding their growth or function. The coated bacteria, which produce ammonia, could make it much easier for farmers to deploy microbes as fertilizers.
Published Water splitting reaction for green hydrogen gas production improved
(via sciencedaily.com) Original source Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have now designed an electrode with Schottky Junction formed at the interface of metallic Ni-W5N4 and semiconducting NiFeOOH. The proposed electrode shows excellent catalytic activity and can facilitate industrial seawater splitting continuously for 10 days.
Published New scientific study reveals the crucial role of herbivorous fishes and sea urchins in restoring Caribbean coral reefs
