Published New deep learning AI tool helps ecologists monitor rare birds through their songs
(via sciencedaily.com) Original source Researchers have developed a new deep learning AI tool that generates life-like birdsongs to train bird identification tools, helping ecologists to monitor rare species in the wild.
Published Not so silver lining: Microplastics found in clouds could affect the weather
(via sciencedaily.com) Original source From the depths of the seas to snow on mountains and even the air above cities, microplastics are turning up increasingly often. Now, researchers have analyzed microplastics in clouds above mountains. They suggest that these tiny particles could play a role in cloud formation and, in turn, affect weather.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers
(via sciencedaily.com) Original source Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
Published Melting ice falling snow: Sea ice declines enhance snowfall over West Antarctica
(via sciencedaily.com) Original source As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise.
Published New water treatment method can generate green energy
(via sciencedaily.com) Original source Researchers have designed micromotors that move around on their own to purify wastewater. The process creates ammonia, which can serve as a green energy source. Now, an AI method will be used to tune the motors to achieve the best possible results.
Published Study sheds light on how Earth cycles fossil-carbon
(via sciencedaily.com) Original source Researches used rhenium as a proxy for fossil carbon in order to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and found that high rates of carbon breakdown persist across the different geographical profiles of a river basin.
Published Forecasting microbiomes for sustainability and health
(via sciencedaily.com) Original source Microbial communities, or microbiomes, are essential for safeguarding human and environmental health through the most widely used biotechnological process on our planet: biological wastewater treatment. However, the process itself is subject to constant changes, difficult to sustain over long periods of time and emits significant amounts of greenhouse gases.
Published Europe was not covered by dense forest before the arrival of modern humans
(via sciencedaily.com) Original source For decades, we believed that outside ice ages Europe was mostly covered by dense forest before the arrival of modern humans. Now, a new study shows that there was far more open and semi-open vegetation than conventionally expected.
Published Faster Arctic warming hastens 2C rise by eight years
(via sciencedaily.com) Original source The Arctic is currently warming nearly four times faster than the global average rate. The new study aimed to estimate the impact of this faster warming on how quickly the global temperature thresholds of 1.5C and 2C, set down in the Paris Agreement, are likely to be breached.
Published 'Cooling glass' blasts building heat into space
(via sciencedaily.com) Original source Researchers aiming to combat rising global temperatures have developed a new 'cooling glass' that can turn down the heat indoors without electricity by drawing on the cold depths of space. The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10 percent.
Published Ammonia for fertilizers without the giant carbon footprint
(via sciencedaily.com) Original source Green ammonia has the potential to drastically reduce the carbon footprint needed to produce fertilizer vital for crop-growing.
Published North Atlantic's marine productivity may not be declining, according to new study of older ice cores
(via sciencedaily.com) Original source To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. Analysis of a Greenland ice core going back 800 years shows that atmospheric chemistry, not dwindling phytoplankton populations, explains the industrial-era ice core trends.
Published Ammonia fuel offers great benefits but demands careful action
(via sciencedaily.com) Original source Researchers have identified the potential environmental risks of using ammonia as a zero-carbon fuel in order to develop an engineering roadmap to a sustainable ammonia economy.
Published A 'fish cartel' for Africa could benefit the countries, and their seas
(via sciencedaily.com) Original source Banding together to sell fishing rights could generate economic benefits for African countries, which receive far less from access to their fisheries on the global market than other countries do from theirs. By joining forces, researchers say African fisheries would not just secure more competitive access fees, they could also protect their seas' biodiversity.
Published How climate change could be affecting your brain
(via sciencedaily.com) Original source A new element of the catastrophic impacts of climate change is emerging -- how global warming is impacting the human brain.
Published Wildfire, drought cause $11.2 billion in damage to private timberland in three Pacific states, study finds
(via sciencedaily.com) Original source Wildfires and drought have led to $11.2 billion in damages to privately held timberland in California, Oregon and Washington over the past two decades, a new Oregon State University study found.
Published New research maps 14 potential evolutionary dead ends for humanity and ways to avoid them
(via sciencedaily.com) Original source Humankind risks getting stuck in 14 evolutionary dead ends, ranging from global climate tipping points to misaligned artificial intelligence, chemical pollution, and accelerating infectious diseases, finds a new major assessment by scientists from multiple different disciplines. To break these trends, humans must become self-aware of our common futures.
Published Capture or reuse CO2 as a chemical source for the production of sustainable plastics
(via sciencedaily.com) Original source Chemists have developed a new polyurethane production technique using CO2 to create new types of easily recyclable plastics that uses more sustainable materials to produce plastics with properties similar to conventional petro-sourced plastics. This new technology is emerging as a potential solution for the development of sustainable plastics with a wide range of properties that can easily meet the needs of most of our everyday applications.
Published Aerosols: When scents influence our climate
(via sciencedaily.com) Original source Tiny particles that form from molecules in the air play an important role for climate change. But until now, the have been poorly understood. Scientists have now analyzed how these particles form.
Published Endangered turtle population under threat as pollution may lead to excess of females being born
(via sciencedaily.com) Original source Researchers find exposure to heavy metals cadmium and antimony and certain organic contaminants, accumulated by the mother and transferred to her eggs, may cause embryos to be feminized in green sea turtles (Chelonia mydas), a species already at risk of extinction from a current lack of male hatchlings.
