Published Death toll shows extreme air pollution events a growing urban threat
(via sciencedaily.com) Original source New research has estimated that 1454 avoidable deaths (one person every five days) occurred in Australian capital cities in the past 20 years because of fine particle air pollution from extreme events such as bushfires and dust storms, wood-heater smoke or industrial accidents.
Published Unprecedented ocean heating shows risks of a world 3°C warmer
(via sciencedaily.com) Original source New research examines the causes of the record-breaking ocean temperatures witnessed in 2023.
Published Fungal-rich soil may improve green roofs
(via sciencedaily.com) Original source Green roofs have become increasingly popular thanks to their benefits related to climate adaptation, mitigation, and urban biodiversity management. But, in the U.S., green roofs are typically planted with non-native plants in sterile soils, and their effectiveness declines over time. A new study finds that managing green roof soil microbes boosts healthy urban soil development, which is a methodology that could be applied to support climate resilience in cities.
Published As sea otters recolonize California estuary, they restore its degraded geology
(via sciencedaily.com) Original source As sea otters recolonize a California estuary, they are restoring its degraded geology by keeping populations of overgrazing marsh crabs in check, a new study shows. The crabs' appetite for plant roots, and their tunneling behavior had caused many of the estuary's marshes and creekbanks to erode and collapse in the otters' absence. Today, erosion has slowed by up to 90% in areas with large otter populations and marshes and streambeds are restabilizing.
Published A green alternative for treating Streptococcus iniae bacteria in hybrid striped bass
(via sciencedaily.com) Original source Scientists have developed a green antibiotic alternative to treat the deadly pathogen Streptococcus iniae in hybrid striped bass, the fourth most farmed finfish in the United States, according to a recent study.
Published Compounding risks of atmospheric river storms
(via sciencedaily.com) Original source When storms hit back-to-back, the flooding -- and economic damages -- are even worse than expected.
Published First-ever sighting of a live newborn great white
(via sciencedaily.com) Original source Great whites, the largest predatory sharks in the world with the most fatal attacks on humans, are tough to imagine as newborn babies. That is partially because no one has seen one in the wild, it seems, until now.
Published Researchers map genome for cats, dolphins, birds, and dozens of other animals
(via sciencedaily.com) Original source Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.
Published Use it or lose it: How seagrasses conquered the sea
(via sciencedaily.com) Original source Seagrasses provide the foundation of one of the most highly biodiverse, yet vulnerable, coastal marine ecosystems globally. They arose in three independent lineages from their freshwater ancestors some 100 million years ago and are the only fully submerged, marine flowering plants. Moving to such a radically different environment is a rare evolutionary event and definitely not easy. How did they do it? New reference quality genomes provide important clues with relevance to their conservation and biotechnological application.
Published Unexpected biodiversity on the ocean floor
(via sciencedaily.com) Original source Hydrothermal vents and manganese nodule fields in the deep oceans contain more biodiversity than expected.
Published Diverse forests are best at standing up to storms
(via sciencedaily.com) Original source European forests with a greater diversity of tree species are more resilient to storms, according to new research.
Published Microplastics may be accumulating rapidly in endangered Galápagos penguins' food web
(via sciencedaily.com) Original source Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
Published Humpback whales move daytime singing offshore
(via sciencedaily.com) Original source New research revealed a daily pattern wherein humpback whales move their singing away from shore throughout the day and return to the nearshore in the evening.
Published Self-powered movable seawall for tsunami protection and emergency power generation
(via sciencedaily.com) Original source A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers. The system has been found feasible in areas prone to Nankai Trough earthquake tsunamis. Additionally, it can generate surplus energy to supply emergency power to ports during power outages that commonly occur in natural disasters. This innovative system integrates disaster prevention with the use of renewable energy.
Published Global warming has a bigger effect on compact, fast-moving typhoons
(via sciencedaily.com) Original source A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.
Published Paper provides a clearer picture of severe hydro hazards
(via sciencedaily.com) Original source A new study now provides a global examination of drought-pluvial volatility -- or the tendency to shift from one weather extreme to another.
Published New tool predicts flood risk from hurricanes in a warming climate
(via sciencedaily.com) Original source A new method predicts how much flooding a coastal community is likely to experience as hurricanes evolve due to climate change. Using New York as a test case, the model predicts Hurricane Sandy-level flooding will occur roughly every 30 years by 2099.
Published Marine heat waves trigger shift in hatch dates and early growth of Pacific cod
(via sciencedaily.com) Original source Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study shows. These changes in the hatch cycle and early growth patterns persisted in years following the marine heat waves, which could have implications for the future of Gulf of Alaska Pacific cod, an economically and culturally significant species.
Published Links discovered between weather patterns and power outages could help UK protect itself from disruptive weather
(via sciencedaily.com) Original source The behavior of specific weather patterns and their impact on power faults could be used to develop a weather pattern - conditioned fault forecasting system for power system operators.
Published Don't blame the sharks: Why more hooked tarpon are being eaten
(via sciencedaily.com) Original source In wave-making research, a team of biologists has quantified the rate at which great hammerhead sharks are eating Atlantic tarpon hooked by anglers at Bahia Honda, Florida -- one of the prime tarpon fishing spots in the Florida Keys.
