Published A single Bitcoin transaction could cost as much water as a backyard swimming pool
(via sciencedaily.com) Original source Cryptocurrency mining uses a significant amount of water amid the global water crisis, and its water demand may grow further. Researchers provides the first comprehensive estimate of Bitcoin's water use. He warns that its sheer scale could impact drinking water if it continues to operate without constraints, especially in countries that are already battling water scarcity, including the U.S.
Published Antarctic glacier retreating rapidly
(via sciencedaily.com) Original source Scientists are warning that apparently stable glaciers in the Antarctic can 'switch very rapidly' and lose large quantities of ice as a result of warmer oceans. Their finding comes after glaciologists used satellites to track the Cadman Glacier, which drains into Beascochea Bay, on the west Antarctic peninsula.
Published Giant sea salt aerosols play major role in Hawai'i's coastal clouds, rain
(via sciencedaily.com) Original source A new study from atmospheric scientists revealed that the coastline can produce up to five times the concentration of giant sea salt aerosols compared to the open ocean and that coastal clouds may contain more of these particles than clouds over the open ocean -- affecting cloud formation and rain around the Hawaiian Islands.
Published Recycled phosphorus fertilizer reduces nutrient leaching, maintains yield
(via sciencedaily.com) Original source A promising new form of ammonium phosphate fertilizer has been field-tested. The fertilizer, struvite, offers a triple win for sustainability and crop production, as it recycles nutrients from wastewater streams, reduces leaching of phosphorus and nitrogen in agricultural soils, and maintains or improves soybean yield compared to conventional phosphorus fertilizers.
Published Promising salt for heat storage
(via sciencedaily.com) Original source Salt batteries can store summer heat to be used in winter, but which salt works best for the purpose?
Published Future floods: Global warming intensifies heavy rain -- even more than expected
(via sciencedaily.com) Original source The intensity and frequency of extreme rainfall increases exponentially with global warming, a new study finds. The analysis shows that state-of-the-art climate models significantly underestimate how much extreme rainfall increases under global warming -- meaning that extreme rainfall could increase quicker than climate models suggest.
Published Separating out signals recorded at the seafloor
(via sciencedaily.com) Original source Research shows that variations in pyrite sulfur isotopes may not represent the global processes that have made them such popular targets of analysis and interpretation. A new microanalysis approach helps to separate out signals that reveal the relative influence of microbes and that of local climate.
Published 'Dolomite Problem': 200-year-old geology mystery resolved
(via sciencedaily.com) Original source For 200 years, scientists have failed to grow a common mineral in the laboratory under the conditions believed to have formed it naturally. Now, researchers have finally pulled it off, thanks to a new theory developed from atomic simulations. Their success resolves a long-standing geology mystery called the 'Dolomite Problem.' Dolomite -- a key mineral in the Dolomite mountains in Italy, Niagara Falls, the White Cliffs of Dover and Utah's Hoodoos -- is very abundant in rocks older than 100 million years, but nearly absent in younger formations. The lessons learned from the Dolomite Problem can help engineers manufacture higher-quality materials for semiconductors, solar panels, batteries and other tech.
Published Predicting the fate of shallow coastal ecosystems for the year 2100
(via sciencedaily.com) Original source A new study of shallow-water ecosystems estimates that, by 2100, climate change and coastal land usage could result in significant shrinkage of coral habitats, tidal marshes, and mangroves, while macroalgal beds remain stable and seagrass meadows potentially expand.
Published Deep-sea mining and warming trigger stress in a midwater jellies
(via sciencedaily.com) Original source The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.
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 Long in the Bluetooth: Scientists develop a more efficient way to transmit data between our devices
(via sciencedaily.com) Original source Researchers have developed a more energy efficient way of connecting our personal devices. New technology consumes less power than Bluetooth and can improve battery life of tech accessories, including earbuds and fitness trackers. Future applications could see us unlocking a door by touching its handle or shaking hands to exchange phone numbers.
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 Coastal river deltas threatened by more than climate change
(via sciencedaily.com) Original source Worldwide, coastal river deltas are home to more than half a billion people, supporting fisheries, agriculture, cities, and fertile ecosystems. In a unique study covering 49 deltas globally, researchers have identified the most critical risks to deltas in the future. The research shows that deltas face multiple risks, and that population growth and poor environmental governance might pose bigger threats than climate change to the sustainability of Asian and African deltas, in particular.
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 Heat tolerant coral may trade fast growth for resilience
(via sciencedaily.com) Original source Algae living within the soft tissue of coral supply much of the energy needed by their hosts, and some symbiotic algae help coral withstand warmer water better than others. Researchers have now found that there was a tradeoff for corals dominated by the thermally sensitive algae -- they have higher growth, but only in cooler water.
Published Dams now run smarter with AI
(via sciencedaily.com) Original source Scientists have leveraged artificial intelligence models to enhance dam operations.
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 Microplastics in soil: Tomography with neutrons and X-rays shows where particles are deposited
(via sciencedaily.com) Original source It is a real problem: Microplastic particles are everywhere. Now a team has developed a method that allows it for the first time to precisely localise microplastic particles in the soil. The 3D tomographies show where the particles are deposited and how structures in the soil are changed. The method was validated on prepared samples.
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.
