Published Health risk from global warming predictor of city climate action during COVID-19, study finds
(via sciencedaily.com) Original source City officials were more likely to maintain climate action during the pandemic in places with more climate-related health issues affecting residents.
Published Slugs and snails love the city, unlike other animals
(via sciencedaily.com) Original source Most native species avoid more urbanized areas of Los Angeles, but slugs and snails may actually prefer these environments, according to a new study.
Published Research to uncover the impact of water use in the Colorado River Basin
(via sciencedaily.com) Original source Persistent overuse of water and long-term drought has depleted the Colorado River and highlighted the need for a comprehensive understanding of how waters are allocated and used to develop effective management strategies.
Published Altering cancer treatment dosing could reduce climate impact, study finds
(via sciencedaily.com) Original source Changing how often a popular cancer therapy is delivered would reduce greenhouse gas emissions and improve environmental impact without decreasing cancer survival, according to a new analysis.
Published Smarter foragers do not forage smarter
(via sciencedaily.com) Original source Why do primates have big brains? In the Panamanian rainforest, scientists pitted large-brained primates against smaller-brained mammals to find out who was the smartest forager.
Published A unified account of Darwinism's varieties
(via sciencedaily.com) Original source A new article examines the question of what Darwinism is and how its nonscientific uses relate to the scientific theory of evolution. The authors observe that while some people claim Darwinism's meaning should be limited to scientific content, others call for its abolition altogether. The authors propose a unified account of these varieties of Darwinism.
Published Bringing back an ancient bird
(via sciencedaily.com) Original source Using ancient DNA extracted from the toe bone of a museum specimen, biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. The work is the first complete genetic map of the turkey-sized bird whose distant living cousins include the ostrich, emu, and kiwi.
Published Performance of eco-friendly cooling applications enhanced
(via sciencedaily.com) Original source Researchers have developed a sustainable and controllable strategy to manipulate interfacial heat transfer, paving the way for improving the performance of eco-friendly cooling in various applications such as electronics, buildings and solar panels.
Published Wind farms are cheaper than you think -- and could have prevented Fukushima, says global review
(via sciencedaily.com) Original source Offshore wind could have prevented the Fukushima disaster, according to a review of wind energy.
Published Improved refrigeration could save nearly half of the 1.3 billion tons of food wasted each year globally
(via sciencedaily.com) Original source A new study concludes that nearly half of the food waste, about 620 million metric tons, could be eliminated by fully refrigerated food supply chains worldwide. At the same time, fully refrigerated supply chains, or 'cold chains,' could cut food waste-related emissions of climate-warming greenhouse gases by 41% globally, according to a new study.
Published Prenatal exposure to air pollution associated with increased mental health risks
(via sciencedaily.com) Original source A baby's exposure to air pollution while in the womb is associated with the development of certain mental health problems once the infant reaches adolescence, new research has found. The study examined the long-term mental health impact of early-life exposure to air and noise pollution.
Published Study suggests 'biodegradable' teabags don't readily deteriorate in the environment and can adversely affect terrestrial species
(via sciencedaily.com) Original source New research looked at commonly available teabags made using three different compositions of polylactic acid (PLA), which is derived from sources such as corn starch or sugar cane. The teabags were buried in soil for seven months, and a range of techniques were then used to assess whether -- and to what extent -- they had deteriorated. The results showed that teabags made solely from PLA remained completely intact. However, the two types of teabags made from a combination of cellulose and PLA broke down into smaller pieces, losing between 60% and 80% of their overall mass and with the PLA component remaining.
Published Inexpensive microplastic monitoring through porous materials and machine learning
(via sciencedaily.com) Original source Optical analysis and machine learning techniques can now readily detect microplastics in marine and freshwater environments using inexpensive porous metal substrates.
Published Genetic mosaicism more common than thought
(via sciencedaily.com) Original source Researchers found that approximately one in 40 human bone marrow cells carry massive chromosomal alterations without causing any apparent disease or abnormality. Even so-called normal cells carry all sorts of genetic mutations, meaning there are more genetic differences between individual cells in our bodies than between different human beings. The discovery was enabled by a single-cell sequencing technology called Strand-seq, a unique DNA sequencing technique that can reveal subtle details of genomes in single cells that are too difficult to detect with other methods.
Published How killifish embryos use suspended animation to survive over 8 months of drought
(via sciencedaily.com) Original source The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish's embryos enter a state of extreme suspended animation or 'diapause' for approximately 8 months. Now, researchers have uncovered the mechanisms that enabled the killifish to evolve this extreme survival state.
Published Simple food swaps could cut greenhouse gas emissions from household groceries by a quarter
(via sciencedaily.com) Original source Switching food and drink purchases to very similar but more environmentally friendly alternatives could reduce the greenhouse gas emissions from household groceries by more than a quarter (26%), according to a new study.
Published Global activity of seafloor biodiversity mapped
(via sciencedaily.com) Original source A team of scientists has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world.
Published Secrets of sargassum: Scientists advance knowledge of seaweed causing chaos in the Caribbean and West Africa
(via sciencedaily.com) Original source A research team tracked and studied floating sargassum in order to unlock its potential to be used to produce sustainable products.
Published Echidnapus identified from an 'Age of Monotremes'
(via sciencedaily.com) Original source Australian researchers have found evidence of the oldest known platypus and a new species, dubbed 'echidnapus', which has a platypus-like anatomy alongside features that more closely resemble an echidna.
Published Combating carbon footprint: Novel reactor system converts carbon dioxide into usable fuel
(via sciencedaily.com) Original source Boilers are a major source of greenhouse gas emissions. In a recent study, researchers developed a method to convert CO2 emissions from small boilers into methane, which makes use of an optimized reactor design that evenly distributes the CO2 feed. This, in turn, results in significantly lower temperature increments and a boost in methane production. This innovative technique could pave the way for reducing greenhouse gas emissions.
