Published New animal welfare scoring system could enable better-informed food and farming choices
(via sciencedaily.com) Scientists have come up with a system of measuring animal welfare that enables reliable comparison across different types of pig farming.
Published The devil is in the details: Re-imagining fertilizer precursor synthesis
(via sciencedaily.com) Researchers have improved the Faradaic efficiency of the nitrogen reduction reaction into ammonia by straightforward optimization of chemical process parameters. They found that trace water was the probable source of the high selectivity by facilitating incorporation of lithium oxide into the solid electrolyte interphase. These findings will also aid optimization of other analogous reactions, and thus help the chemicals industry optimize the sustainability of one of the most carbon-intensive reactions globally.
Published Synthesis gas and battery power from sunlight energy
(via sciencedaily.com) Plants use photosynthesis to harvest energy from sunlight. Now researchers have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.
Published Human and ocean health impacts of ocean plastics
(via sciencedaily.com) Researchers from the fields of healthcare, ocean science, and social science have collaborated to quantify plastic's considerable risks to all life on Earth. The Minderoo-Monaco Commission on Plastics and Human Health report presents a comprehensive analysis showing plastics as a hazard at every stage of their life cycle.
Published Galaxy changes classification as jet changes direction
(via sciencedaily.com) A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed otherwise.
Published Nitrate can release uranium into groundwater
(via sciencedaily.com) A team has experimentally confirmed that nitrate, a compound common in fertilizers and animal waste, can help transport naturally occurring uranium from the underground to groundwater. The new research backs a previous study showing that aquifers contaminated with high levels of nitrate -- including the High Plains Aquifer residing beneath Nebraska -- also contain uranium concentrations far exceeding a threshold set by the Environmental Protection Agency. Uranium concentrations above that EPA threshold have been shown to cause kidney damage in humans, especially when regularly consumed via drinking water.
Published Scientists find a common thread linking subatomic color glass condensate and massive black holes
(via sciencedaily.com) Atomic nuclei accelerated close to the speed of light become dense walls of gluons known as color glass condensate (CGC). Recent analysis shows that CGC shares features with black holes, enormous conglomerates of gravitons that exert gravitational force across the universe. Both gluons in CGC and gravitons in black holes are organized in the most efficient manner possible for each system's energy and size.
Published Douglas-fir in Klamath Mountains are in 'decline spiral'
(via sciencedaily.com) Increases in mortality among Douglas-fir in the Klamath Mountains are the result of multiple factors that have the iconic tree in a 'decline spiral' in parts of the region.
Published Biodiversity amid climate change
(via sciencedaily.com) Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.
Published Recycling: Researchers separate cotton from polyester in blended fabric
(via sciencedaily.com) Researchers found they could separate blended cotton and polyester fabric using enzymes -- nature's tools for speeding chemical reactions. Ultimately, they hope their findings will lead to a more efficient way to recycle the fabric's component materials, thereby reducing textile waste.
Published Coffee plantations limit birds' diets
(via sciencedaily.com) A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.
Published Rivers and streams in the Andean Cordillera are hot spots for greenhouse gases emissions
(via sciencedaily.com) Researchers show that rivers in the Andean mountains contribute 35% and 72% of riverine emissions of carbon dioxide (CO2 ) and methane (CH4 ) in the Amazon basin, the world's largest river.
Published New study counts the environmental cost of managing Japanese knotweed
(via sciencedaily.com) New research has looked at the long-term environmental impact of different methods to control Japanese knotweed. Different ways of trying to control the invasive species have developed over the years but now, as sustainability becomes increasingly important, understanding the effect of these management methods is vital.This new study examines at the entire life cycle and long-term impacts of different management approaches.
Published Fossil site is 'Rosetta Stone' for understanding early life
(via sciencedaily.com) Leading edge technology has uncovered secrets about a world-renowned fossil hoard that could offer vital clues about early life on Earth. Researchers who analyzed the 400 million-year-old cache, found in rural north-east Scotland, say their findings reveal better preservation of the fossils at a molecular level than was previously anticipated.
Published Electronic skin as flexible as crocodile skin
(via sciencedaily.com) A research team has developed a crocodile-skin-inspired omnidirectionally stretchable pressure sensor.
Published 'Terminator zones' on distant planets could harbor life
(via sciencedaily.com) In a new study, astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the 'terminator zone,' which is a ring on planets that have one side that always faces its star and one side that is always dark.
Published New approach to harvesting aerial humidity with organic crystals
(via sciencedaily.com) Researchers have reported a novel method of harvesting water from naturally occurring sources such as fog and dew.
Published Recovering tropical forests offset just one quarter of carbon emissions from new tropical deforestation and forest degradation
(via sciencedaily.com) A pioneering global study has found deforestation and forests lost or damaged due to human and environmental change, such as fire and logging, are fast outstripping current rates of forest regrowth.
Published Designing more useful bacteria
(via sciencedaily.com) In a step forward for genetic engineering and synthetic biology, researchers have modified a strain of Escherichia coli bacteria to be immune to natural viral infections while also minimizing the potential for the bacteria or their modified genes to escape into the wild.
Published Extensive catalog of exploding stars
(via sciencedaily.com) The largest data release of relatively nearby supernovae (colossal explosions of stars), containing three years of data is publicly available via the Young Supernova Experiment (YSE).
