Published Tropical coral-infecting parasites discovered in cold marine ecosystems
(via sciencedaily.com) Original source Parasites thought only to infect tropical coral reefs have been discovered in a large variety of creatures in cold marine ecosystems along the Northeast Pacific, according to new research.
Published Ocean currents threaten to collapse Antarctic ice shelves
(via sciencedaily.com) Original source Meandering ocean currents play an important role in the melting of Antarctic ice shelves, threatening a significant rise in sea levels.
Published Microplastic 'hotspots' identified in Long Island Sound
(via sciencedaily.com) Original source Forensic and environmental experts have teamed up to develop a new scientific method to pinpoint microplastic pollution 'hotspots' in open waters.
Published New approach needed to save Australia's non-perennial rivers
(via sciencedaily.com) Original source An extensive review of current research incorporating geomorphology, hydrology, biogeochemistry, ecology and Indigenous knowledges identifies prevailing factors that shape water and energy flows in Australia's non-perennial rivers -- but the review also points to research deficiencies that must be addressed if these river systems are to be preserved and protected.
Published A microbial plastic factory for high-quality green plastic
(via sciencedaily.com) Original source Engineered bacteria can produce a plastic modifier that makes renewably sourced plastic more processable, more fracture resistant and highly biodegradable even in sea water. The development provides a platform for the industrial-scale, tunable production of a material that holds great potential for turning the plastic industry green.
Published Scientist helps link climate change to Madagascar's megadrought
(via sciencedaily.com) Original source A team reveals a clear link between human-driven climate change and the years-long drought currently gripping southern Madagascar.
Published Tiny plastic particles are found everywhere
(via sciencedaily.com) Original source Microplastic particles can be found in the most remote ocean regions on earth. In Antarctica, pollution levels are even higher than previously assumed.
Published Subterranean storage of hydrogen
(via sciencedaily.com) Original source Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
Published Humans converted at least 250,000 acres of estuaries to cities, farms in last 35 years
(via sciencedaily.com) Original source Worldwide over the past 35 years, dams and land reclamation activities converted 250,000 acres of estuary -- an area roughly 17 times the size of Manhattan -- to urban land or agricultural fields, with most land conversion and estuary loss in rapidly developing countries, a new study finds. The findings could help developing countries avoid problems faced by countries that have already lost or degraded their estuaries.
Published A smarter city skyline for flood safety
(via sciencedaily.com) Original source With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. Researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding. Based on their simulated results, the team recommends modifying building corners and protective block layouts to reduce pedestrian risk.
Published How climate change will impact food production and financial institutions
(via sciencedaily.com) Original source Researchers have developed a new method to predict the financial impacts climate change will have on agriculture, which can help support food security and financial stability for countries increasingly prone to climate catastrophes.
Published Deep parts of Great Barrier Reef 'insulated' from global warming -- for now
(via sciencedaily.com) Original source Some deeper areas of the Great Barrier Reef are insulated from harmful heatwaves -- but that protection will be lost if global warming continues, according to new research.
Published PFAS 'forever chemicals' above drinking water guidelines in global source water
(via sciencedaily.com) Original source PFAS (aka 'forever chemicals') are notoriously difficult to destroy. They've been linked to environmental and health issues, including some cancers, but a lot remains unknown about the true scale and potential impacts of the problem -- including how much is in our water supply. A new study assessed the levels of PFAS contamination in surface and ground water around the globe -- and found that much of our global source water exceeds PFAS safe drinking limits.
Published Climate change threatens Antarctic meteorites
(via sciencedaily.com) Original source Antarctica harbors a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our solar system. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming, according to a new study.
Published Common loons threatened by declining water clarity
(via sciencedaily.com) Original source The Common Loon, an icon of the northern wilderness, is under threat from climate change due to reduced water clarity, according to a new study. The study followed up an earlier paper that showed substantial reproductive decline in the author's study area in northern Wisconsin.
Published eDNA methods give a real-time look at coral reef health
(via sciencedaily.com) Original source The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.
Published Neutron stars are key to understanding elusive dark matter
(via sciencedaily.com) Original source Scientists may be one step closer to unlocking one of the great mysteries of the universe after calculating that neutron stars might hold a key to helping us understand elusive dark matter.
Published Heat stress from ocean warming harms octopus vision
(via sciencedaily.com) Original source While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.
Published What four decades of canned salmon reveal about marine food webs
(via sciencedaily.com) Original source Researchers have shown that levels of anisakid worms -- a common marine parasite -- rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.
Published Researchers envision sci-fi worlds involving changes to atmospheric water cycle
(via sciencedaily.com) Original source Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture. Researchers enlisted water scientists from around the globe to write story-based scenarios about the possible futures humanity is facing but perhaps can't quite comprehend yet. The results are part of a creative pathway to understand atmospheric water research with an eye towards the potential economic and policy issues that may be just beyond the horizon.
