Published Sustainable and reversible 3D printing method uses minimal ingredients and steps
(via sciencedaily.com) Original source A new 3D printing method developed by engineers is so simple that it uses a polymer ink and salt water solution to create solid structures. The work has the potential to make materials manufacturing more sustainable and environmentally friendly.
Published Multiple urinary metals play key role in cardiovascular disease and mortality, study finds
(via sciencedaily.com) Original source Higher levels of urinary metals such as cadmium, tungsten, uranium, cobalt, copper and zinc are linked to increased cardiovascular disease and mortality in a racially and ethnically diverse U.S. population, according to a new study.
Published Warming stops tiny organisms working together
(via sciencedaily.com) Original source Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
Published Underwater mapping reveals new insights into melting of Antarctica's ice shelves
(via sciencedaily.com) Original source Clues to future sea level rise have been revealed by the first detailed maps of the underside of a floating ice shelf in Antarctica. An international research team deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica.
Published Barriers designed to prevent saltwater intrusion may worsen inland flooding
(via sciencedaily.com) Original source Building protection barriers without accounting for potential inland flooding risks from groundwater can eventually worsen the very issues they aim to solve.
Published Green hydrogen: 'Artificial leaf' becomes better under pressure
(via sciencedaily.com) Original source Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.
Published New collaborative research generates lessons for more adaptive lake management
(via sciencedaily.com) Original source A professor gathered feedback from 26 Colorado River Basin managers and experts took on water user roles to discuss consuming, banking and trading Colorado River water.
Published New more sustainable method for manufacturing microchips and other nanoscale devices
(via sciencedaily.com) Original source Researchers develop a more environmentally friendly approach to manufacturing nano-scale microchip devices using water as a solvent in place of toxic chemicals. The method not only cleans up the manufacturing waste stream, but also enables the integration of electronic and biological components.
Published How researchers turn bacteria into cellulose-producing mini-factories
(via sciencedaily.com) Original source Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.
Published California a botanical and climate change hot spot
(via sciencedaily.com) Original source Climate-driven shifts in California's biodiversity call for innovation and continued environmental stewardfship, says a new study. California's 30x30 Initiative and efforts to harmonize biodiversity with renewable energy are promising steps, while wildfire strategies need to further adapt.
Published Bold moves needed for California agriculture to adapt to climate change
(via sciencedaily.com) Original source California needs urgent and bold measures to adapt its $59 billion agriculture sector to climate change as the amount of water available for crops declines, according to a new report. The report provides a roadmap for more water capture, storage, and distribution systems that are in harmony with climate projections and ecosystems. It further considers how runoff and groundwater can be used repeatedly as it flows generally from mountainsides to coastal lands.
Published Plant-inspired polymers for water purification
(via sciencedaily.com) Original source Researchers have synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.
Published New study disputes Hunga Tonga volcano's role in 2023-24 global warm-up
(via sciencedaily.com) Original source New research is exploring the climate impact of the 2022 Hunga Tonga volcano eruption and challenging existing assumptions about its effects in the process.
Published Thousands of birds and fish threatened by mining for clean energy transition, study finds
(via sciencedaily.com) Original source Our increasing demand for metals and minerals is putting over four thousand vertebrate species at risk, with the raw materials needed for clean energy infrastructure often located in global biodiversity hotspots, a study has found.
Published Nitrogen emissions have a net cooling effect: But researchers warn against a climate solution
(via sciencedaily.com) Original source An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming.
Published Solar absorption by black carbon in fire clouds quantified
(via sciencedaily.com) Original source Aerosol scientists quantify the extent of light absorption by black carbon in fire clouds to better model climate impacts of extreme wildfire events.
Published Great Salt Lake a significant source of greenhouse gas emissions
(via sciencedaily.com) Original source Newly announced research examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020. This research suggests that drying lake beds are an overlooked but potentially significant source of greenhouse gases, which may further increase due to climate change.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine
(via sciencedaily.com) Original source Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published Scientists study how to bring you 'climate-smart coffee'
(via sciencedaily.com) Original source Coffee beans consumed across the globe come from two species: Coffea arabica and Coffea canephora. By 2050, about 80% of Arabica production is predicted to decrease because of climate change. Researchers are investigating to see if they can find alternative coffee cultivars.
Published Better way to produce green hydrogen
(via sciencedaily.com) Original source Researchers have developed a material that shows a remarkable ability to convert sunlight and water into clean energy.
