Published Aerosol pollution, greenhouse gases must be reduced simultaneously to keep forest fires in check
(via sciencedaily.com) Original source If we want cleaner air, fewer forest fires, and less severe climate change, a new study shows we must reduce aerosol pollution and greenhouse gases like carbon dioxide at the same time.
Published Fatal attraction: When endangered species try to mate with domestic relatives, both wildlife and people lose
(via sciencedaily.com) Original source Sticks and stones aren't enough to thwart biological attraction, but sometimes those are the only tools available to pastoralists trying to prevent wildlife from eloping with their livestock. A new study brings awareness to both the human impacts of these encounters -- ranging from economic loss to death -- and conservation concerns for the wild animals that are often endangered.
Published Some species may tolerate climate change better than expected
(via sciencedaily.com) Original source A new model reassesses the proportion of terrestrial and marine species threatened with extinction by climate change. While the forecasts of traditional models estimate that the diversity of terrestrial species in tropical areas could decrease by 54% between now and 2041-2060, this model is more moderate, predicting a decrease of 39%. Nevertheless, this proportion remains alarming and confirms the importance of taking urgent measures to mitigate climate change and its impact on biodiversity.
Published Biobased building materials less sustainable than concrete in South Africa, experts find
(via sciencedaily.com) Original source Scientists have discovered that mycelium composites, biobased materials made from fungi and agricultural residues, can have a greater environmental impact than conventional fossil-fuel-based materials due to the high amount of electricity involved in their production.
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 Wild megalopolis: Study shows unexpected pockets of biodiversity pepper Los Angeles
(via sciencedaily.com) Original source Researchers, in partnership with the city of Los Angeles, have developed the urban association index to help identify how well or poorly individual wildlife species are doing in the city. The researchers found unexpected pockets of biodiversity deep in the city, but they say it will still be a challenge to elevate Los Angeles' overall level of biodiversity.
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 Marine Protected Areas don't line up with core habitats of rare migratory fish, finds new research
(via sciencedaily.com) Original source 62% of Marine Protected Areas (MPAs) designated to protect rare migratory fish species are outside of their core habitats, according to a new modeling study.
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 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 Harnessing green energy from plants depends on their circadian rhythms
(via sciencedaily.com) Original source Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process. A study closely examined the differences in voltage caused by the concentrations of ions, types of ions, and pH of the fluid plants transport, tying the voltage changes to the plant's circadian rhythm that causes adjustments day and night. According to the authors, this consistent, cyclic voltage creation could be harnessed as an energy source.
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.
