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 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 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 Naturally regrowing forests are helping to protect the remaining old forests in the Amazon
(via sciencedaily.com) Original source Secondary forests that have regrown naturally on land abandoned from agriculture are important in counteracting the effects of forest fragmentation across the Amazon basin, according to new findings.
Published Diverse forests hold huge carbon potential, as long as we cut emissions
(via sciencedaily.com) Original source New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. In brief: Forests have the potential to capture 226 Gigatonnes (Gt) of carbon in areas where they would naturally exist. This forest potential can only be achieved alongside emissions cuts. Sixty-one percent of the forest potential can be achieved by protecting existing forests and allowing them to regrow to maturity. Thirty-nine percent can be achieved by reconnecting fragmented landscapes through community-driven ecosystem restoration and management. A natural diversity of species is needed to maximize the forest carbon potential.
Published Designing cities for 21st-century weather
(via sciencedaily.com) Original source Researchers have investigated how changes in urban land and population will affect future populations' exposures to weather extremes under climate conditions at the end of the 21st century. They used a data-driven model to predict how urban areas across the country will grow by 2100, and found that how a city is laid out or organized spatially has the potential to reduce population exposures to future weather extremes.
Published New cooling ceramic can enhance energy efficiency for the construction sector and help combat global warming
(via sciencedaily.com) Original source Researchers have made a significant breakthrough in developing a passive radiative cooling (PRC) material. The material, known as cooling ceramic, has achieved high-performance optical properties for energy-free and refrigerant-free cooling generation. Its cost-effectiveness, durability and versatility make it highly suitable for commercialization in numerous applications, particularly in building construction.
Published Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage
(via sciencedaily.com) Original source Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
Published A fifth of European Red List flora and fauna species may be at risk of extinction
(via sciencedaily.com) Original source A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.
Published Southern Alaska's national forests key to meeting climate, conservation goals
(via sciencedaily.com) Original source Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
Published Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken
(via sciencedaily.com) Original source Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken. Other threats to UK forests include competition with society for water, viral diseases, and extreme weather affecting forest management.
Published First evidence of how the Asian malaria mosquito is spreading drug-resistant malaria in Africa
(via sciencedaily.com) Original source Research has led to the discovery of the role played by the Asian malaria mosquito (Anopheles stephensi) in the spread of drug and diagnosis-resistant malaria in Africa. Malaria is caused by a parasite which is spread by the bite of blood-sucking mosquitoes. According to the WHO, there were an estimated 247 million cases of malaria worldwide in 2021 with over 600,000 deaths, mostly in Africa. Children under 5 accounted for about 80% of all malaria deaths in the region.
Published Device 'smells' seawater to discover, detect novel molecules
(via sciencedaily.com) Original source Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.
Published 'Biodiversity time machine' provides insights into a century of loss
(via sciencedaily.com) Original source AI analysis shows pollution levels, extreme weather events and increasing temperatures devastates biodiversity in freshwater lakes.
Published City and highway lights threaten mountain lion habitats
(via sciencedaily.com) Original source Artificial light pollution at night threatens mountain lion habitat, making it a factor to consider for wildlife crossings and land use, finds a new study.
Published The fascinating relationship between mice and a plant that flowers once a century in terms of seed dispersal
(via sciencedaily.com) Original source Researchers have discovered several factors that affect field mouse behavior using seeds from dwarf bamboo plants, a plant that flowers once in a century. Their findings not only suggest the previously underappreciated role of mice in the forest ecosystem, but also show that they store small sasa seeds for later use. These challenge a previously held model of mouse behavior.
Published New algae species rewrites understanding of reef systems
(via sciencedaily.com) Original source An international team of marine scientists has identified and officially named four species of algae new to science, challenging previous taxonomical assumptions within the Porolithon genus. The discovery has far-reaching implications for our understanding of the ecological role of these algae in the coral reef ecosystem.
Published Threatened sharks and rays caught off Cyprus
(via sciencedaily.com) Original source Sharks and rays from threatened species are being caught off northern Cyprus, according to a new study by scientists who are working with local authorities and fishers to protect the animals.
Published Crust-forming algae are displacing corals in tropical waters worldwide
(via sciencedaily.com) Original source Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.
