Published New groups of methane-producing organisms in Yellowstone
(via sciencedaily.com) Original source The team verified that microbes found in Yellowstone National Park hot springs produce methane to grow.
Published Study of urban moss raises concerns about lead levels in older Portland neighborhoods
(via sciencedaily.com) Original source Lead levels in moss are as much as 600 times higher in older Portland, Oregon, neighborhoods where lead-sheathed telecommunications cables were once used compared to lead levels in nearby rural areas, a new study of urban moss has found.
Published Warehousing industry increases health-harming pollutants, research shows
(via sciencedaily.com) Original source A new study shows an average 20-percent spike of nitrogen dioxide polluting the air for communities located near huge warehouses. And people of color are harder hit.
Published New study supports stable mantle chemistry dating back to Earth's early geologic history and over its prodigious evolution
(via sciencedaily.com) Original source A new analysis of rocks thought to be at least 2.5 billion years old helps clarify the chemical history of Earth's mantle -- the geologic layer beneath the planet's crust. The findings hone scientists' understanding of Earth's earliest geologic processes, and they provide new evidence in a decades-long scientific debate about the geologic history of Earth. Specifically, the results provide evidence that the oxidation state of the vast majority of Earth's mantle has remained stable through geologic time and has not undergone major transitions, contrary to what has been suggested previously by other researchers.
Published Trees reveal climate surprise -- bark removes methane from the atmosphere
(via sciencedaily.com) Original source Tree bark surfaces play an important role in removing methane gas from the atmosphere.
Published Researchers leveraging AI to train (robotic) dogs to respond to their masters
(via sciencedaily.com) Original source An international collaboration seeks to innovate the future of how a mechanical man's best friend interacts with its owner, using a combination of AI and edge computing called edge intelligence. The overarching project goal is to make the dog come 'alive' by adapting wearable-based sensing devices that can detect physiological and emotional stimuli inherent to one's personality and traits, such as introversions, or transient states, including pain and comfort levels.
Published Drawing water from dry air
(via sciencedaily.com) Original source A prototype device harvests drinking water from the atmosphere, even in arid places.
Published New video test for Parkinson's uses AI to track how the disease is progressing
(via sciencedaily.com) Original source An automated assessment technique that uses artificial intelligence could revolutionize the management of Parkinson's disease.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation
(via sciencedaily.com) Original source Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
Published Best bioenergy crops for sustainable aviation fuels by U.S. region, policy goals
(via sciencedaily.com) Original source Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock -- corn stover, energy sorghum, miscanthus or switchgrass -- performed best in a specific region of the rainfed United States. Their study will help growers and policymakers select the feedstocks most suited to meeting goals like reducing production costs, lowering greenhouse gas emissions and building soil carbon stocks.
Published Children's exposome associated with changes in serum metabolites
(via sciencedaily.com) Original source The combined effect of environmental exposures and unhealthy lifestyle habits can affect children's cardiometabolic health in a way that exceeds their separate effects. A new study shows the benefit of measuring the combined effect of multiple environmental and lifestyle factors.
Published A promising new method uses light to clean up forever chemicals
(via sciencedaily.com) Original source A room-temperature method to decompose perfluoroalkyl substances (PFASs) using visible LED light offers a promising solution for sustainable fluorine recycling and PFAS treatment.
Published Development of 'living robots' needs regulation and public debate
(via sciencedaily.com) Original source Researchers are calling for regulation to guide the responsible and ethical development of bio-hybrid robotics -- a ground-breaking science which fuses artificial components with living tissue and cells.
Published Converting captured carbon to fuel: Study assesses what's practical and what's not
(via sciencedaily.com) Original source A new analysis sheds light on major shortfalls of a recently proposed approach to capture CO2 from air and directly convert it to fuel using electricity. The authors also provide a new, more sustainable, alternative.
Published Genome study informs restoration of American chestnut tree
(via sciencedaily.com) Original source Researchers use genomes to help restore the American chestnut population and adjust species breeding to the changing climate.
Published Deep-ocean floor produces its own oxygen
(via sciencedaily.com) Original source An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that only photosynthetic organisms generate Earth's oxygen. Minerals at the abyssal seafloor appear to act like geobatteries to produce oxygen in a process that does not require sunlight.
Published Waste Styrofoam can now be converted into polymers for electronics
(via sciencedaily.com) Original source A new study describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known as PEDOT:PSS. Researchers also noted that the upgraded plastic waste can be successfully incorporated into functional electronic devices, including silicon-based hybrid solar cells and organic electrochemical transistors.
Published Chemists design novel method for generating sustainable fuel
(via sciencedaily.com) Original source Chemists have been working to synthesize high-value materials from waste molecules for years.
Published Can consciousness exist in a computer simulation?
(via sciencedaily.com) Original source A new essay explores which conditions must be met for consciousness to exist. At least one of them can't be found in a computer.
Published New humidity-driven membrane to remove carbon dioxide from the air
(via sciencedaily.com) Original source A new ambient-energy-driven membrane that pumps carbon dioxide out of the air has been developed by researchers.
