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 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 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 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 Plants that survived dinosaur extinction pulled nitrogen from air
(via sciencedaily.com) Original source Ancient cycad lineages that survived the extinction of the dinosaurs may have done so by relying on symbiotic bacteria in their roots to fix atmospheric nitrogen. The finding came from an effort to understand ancient atmospheres, but became an insight into plant evolution instead.
Published Hemp cannabinoids may have evolved to deter insect pests
(via sciencedaily.com) Original source Cannabinoids, naturally occurring compounds found in hemp plants, may have evolved to deter pests from chewing on them, according to new research that showed higher cannabinoid concentrations in hemp leaves led to proportionately less damage from insect larvae.
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 Unexpected discovery opens bioengineering opportunities for human and plant health
(via sciencedaily.com) Original source An unexpected genetic discovery in wheat has led to opportunities for metabolic engineering of versatile compounds with potential to improve its nutritional qualities and resilience to disease.
Published Climate engineering could slow Antarctic ice loss, study suggests
(via sciencedaily.com) Original source A study reports that scattering sunlight-reflecting particles in the atmosphere -- a theoretical form of climate engineering known as 'stratospheric aerosol injection' -- has potential to slow rapid ice melt in Western Antarctica.
Published Genetic discovery promises high-iron vegetables and cereals
(via sciencedaily.com) Original source A genetic breakthrough has opened new opportunities for iron-fortified vegetables and cereal crops to help address the global health issue of anemia.
Published New deep learning AI tool helps ecologists monitor rare birds through their songs
(via sciencedaily.com) Original source Researchers have developed a new deep learning AI tool that generates life-like birdsongs to train bird identification tools, helping ecologists to monitor rare species in the wild.
Published 'Bouncing' comets could deliver building blocks for life to exoplanets
(via sciencedaily.com) Original source How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers have shown how comets could deposit similar building blocks to other planets in the galaxy.
Published Converting PFAS 'forever chemicals' into valuable compounds
(via sciencedaily.com) Original source Researchers have successfully synthesized ligands called fluorinated N-heterocyclic carbenes (NHCs) from environmentally harmful perfluoroalkenes, a type of synthetic chemicals also referred to as PFAS. These NHCs are valuable for stabilizing unstable molecules and enhancing catalytic efficiency. Through further structural modification, these NHCs are expected to find applications in a wide range of substances, including catalysts and light-emitting materials.
Published Non-native species likely to continue spreading in North America, Australia and Europe
(via sciencedaily.com) Original source Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.
Published New water treatment method can generate green energy
(via sciencedaily.com) Original source Researchers have designed micromotors that move around on their own to purify wastewater. The process creates ammonia, which can serve as a green energy source. Now, an AI method will be used to tune the motors to achieve the best possible results.
