Accounting for oxygen in modeling coastal ecosystems
Driven by climate change and pollution, the decline of oxygen levels in oceans is altering biogeochemical cycles, threatening marine plants, animals and ecosystems. But how accurately are we projecting the fate of marine life? If models of marine eco.....»»
Tsunami sands help scientists assess Cascadia earthquake models
To better understand the scale of past earthquakes and tsunamis, scientists often use earthquake modeling or turn to evidence the tsunamis leave behind, such as sand deposits......»»
Sleight of hand: Australia"s Net Zero target is being lost in accounting tricks, offsets and more gas
In announcing Australia's support for fossil gas all the way to 2050 and beyond, Prime Minister Anthony Albanese has pushed his government's commitment to net zero even further out of reach......»»
Reduced sulfur content in shipping fuel associated with increased maritime atmospheric warming
An 80% reduction in sulfur dioxide shipping emissions observed in early 2020 could be associated with substantial atmospheric warming over some ocean regions, according to a modeling study published in Communications Earth & Environment. The sudden d.....»»
Cheap, dirty leftovers can release pure oxygen: Hexagonal manganites show promise for production on an industrial scale
New materials for producing oxygen may challenge traditional production methods. This is exciting news, because pure oxygen is in demand for many areas in industry and medicine......»»
Researchers show the link between trawls and climate change in the North Sea
Fishing trawls cause significant CO2 emissions as they stir up the carbon bound in the seabed and release it again. It is also clear that they drastically affect ecosystems in the ocean. A new study by the Helmholtz-Zentrum Hereon models the influenc.....»»
A new Hungarian method may aid protein research
In a paper recently published in Nature Communications, the HUN-REN-ELTE Protein Modeling Research Group (Institute of Chemistry) has laid the foundations for a mathematical method, allowing the computer-assisted comparison of the three-dimensional s.....»»
Marine Protected Areas don"t line up with core habitats of rare migratory fish, finds new research
According to a new modeling study, 62% of Marine Protected Areas (MPAs) designated to protect rare migratory fish species are outside of their core habitats. The findings are published in the Journal of Applied Ecology......»»
Researchers develop reusable "sponge" for soaking up marine oil spills—even in chilly northern waters
Oil spills, if not cleaned up quickly and effectively, can cause lasting damage to marine and coastal environments. That's why a team of North American researchers are developing a new sponge-like material that is not only effective at grabbing and h.....»»
Key factors that orchestrate mysterious synchronized coral spawning revealed
Corals play an essential role in ocean ecosystems, and like many organisms, they are under threat from climate change and other human activities. To better protect coral, it's first necessary to understand them, in particular their reproductive life.....»»
Tropical forest resilience to seasonal drought linked to nutrient availability
Tropical forests are highly productive ecosystems, accounting for nearly half of the global forest carbon sink. If tropical forests can no longer remove carbon dioxide from the atmosphere, the effects of climate change may become even more severe......»»
New method for modeling free-ranging animal populations finds macaque numbers smaller than expected
A team of researchers created a new method of modeling to estimate the population of free-ranging animals and in doing so discovered that there were far fewer numbers of an Old World monkey, the macaque, than expected......»»
Thousands flee as cyclone heads towards Bangladesh
Tens of thousands of Bangladeshis left their coastal villages Sunday for concrete storm shelters further inland as the low-lying nation prepared for the expected landfall of an intense cyclone, officials said......»»
Machine identities lack essential security controls, pose major threat
Siloed approaches to securing human and machine identities are driving identity-based attacks across enterprises and their ecosystems, according to CyberArk. The CyberArk 2024 Identity Security Threat Landscape Report was conducted across private and.....»»
Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought to disturbances from humans
Summer is coming and that means more boats in the sea. Danish coastal waters are especially cluttered with small boats in the summertime: Locals water skiing, going fishing or just riding around the beautiful bays and fjords......»»
Improving MgH₂ hydrogen storage with oxygen vacancy-enriched H-V₂O₅ nanosheets as an active H-pump
With the depletion of fossil fuels and global warming, there is an urgent need to seek green, clean, and efficient energy resources. Against this backdrop, hydrogen is considered a potential candidate for replacing fossil fuels due to its high energy.....»»
Machine learning accelerates discovery of high-performance metal oxide catalysts
Researchers have harnessed the power of artificial intelligence to significantly advance the discovery and optimization of multicomponent metal oxide electrocatalysts for the oxygen reduction reaction (ORR)......»»
Beach erosion will make Southern California coastal living five times more expensive by 2050, study predicts
Rising sea levels and urban development are accelerating coastal erosion at an alarming rate in Southern California with significant ripple effects on the region's economy, a USC study reveals......»»
Farm wastewater modeling shows footbaths are source of antimicrobial resistance
New research has mapped wastewater flows on farms and revealed where spikes in antibiotic resistant bacteria in slurry occur, showing that water from copper and zinc footbaths used by dairy animals can cause fluctuations......»»
Half of mangrove ecosystems at risk: conservationists
Half of the world's mangrove ecosystems are at risk of collapse due to climate change, deforestation and pollution, according to a study published Wednesday......»»
