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.....»»
Gulf of Mexico "dead zone" larger than average, scientists find
NOAA-supported scientists have announced that this year's Gulf of Mexico "dead zone"—an area of low to no oxygen that can kill fish and marine life—is approximately 6,705 square miles, the 12th largest zone on record in 38 years of measurement. T.....»»
Sea level changes shaped early life on Earth, fossils show
A newly developed timeline of early animal fossils reveals a link between sea levels, changes in marine oxygen, and the appearance of the earliest ancestors of present-day animals......»»
Getting to the root of a plant"s success
Plants are powerful factories—they can turn basic ingredients like carbon dioxide, water, and sunlight into oxygen, sugars, and plant mass. But plants don't do all of this work on their own......»»
New perspectives for using corals in climate research
Ancient ocean temperatures are most commonly reconstructed by analyzing the ratio of different oxygen atoms in the calcium carbonate remains of fossils. However, this presents many challenges, including a combination of biological processes known as.....»»
Atmospheric rivers shape long-term changes in Arctic moisture variability
Recent decades have seen rapid warming in the Arctic, known as Arctic amplification, which has impacted the Arctic's cryosphere and ecosystems and influenced global weather and climate through changes in atmospheric circulation......»»
S.Africa to trial vaccination of seals after first rabies outbreak
Cape fur seals with rabies have infected at least seven people in South Africa and vaccinations will be trialed to try to contain what is the first documented outbreak of the disease in a marine mammal population, a coastal management official said W.....»»
New method detects environmentally unfriendly chemicals
Substances called polyethylene glycols, or PEGs, are widely used in industry, medical, cosmetics and personal care products. The problem is, when they enter the environment and build up, they can harm ecosystems and natural resources......»»
Scientists identify the predictability limit of oceanic mesoscale eddy tracks in the South China Sea
Oceanic mesoscale eddies (OMEs) are swirling water structures that play a crucial role in ocean dynamics. These eddies transport heat, salt, nutrients, and other materials across the ocean, significantly influencing marine ecosystems and global clima.....»»
Astronomers explain rapid formation of organic macromolecules in protoplanetary disks around young stars
An international team of researchers led by the University of Bern has used observation-based computer modeling to find an explanation for how macromolecules can form in a short time in disks of gas and dust around young stars. These findings could b.....»»
Q&A: Why wildfires don"t just burn, but can also pollute aquatic ecosystems
Last week, wildfires blazed across western Canada, turning the town of Jasper, located near Alberta's Jasper National Park, into ashes. The local government estimated that the fire damaged or destroyed up to half of the town's structures......»»
California a botanical and climate change hot spot
From coastal redwoods and Joshua trees to golden poppies and sagebrush, California is a global botanical hotspot. It's also a place confronted with extreme heat, wildfires and crumbling coastlines......»»
New research offers insight on modeling belief dynamics
Researchers who study belief dynamics often use analogies to understand and model the complex cognitive–social systems that underlie why we believe the things we do and how those beliefs can change over time. Ideas can be transmitted like a virus,.....»»
NASA returns to Arctic to study summer sea ice melt
What happens in the Arctic doesn't stay in the Arctic, and a new NASA mission is helping improve data modeling and increasing our understanding of Earth's rapidly changing climate. Changing ice, ocean, and atmospheric conditions in the northernmost p.....»»
AI and ML enter motorsports: How GM is using them to win more races

The Mysterious Discovery of ‘Dark Oxygen’ on the Ocean Floor
Researchers believe they have discovered oxygen being produced 4,000 meters below the sea surface, and think polymetallic nodules—the sought-after bounty of deep-sea miners—could be the source......»»
Surface oxygen functionality controls selective transport of metal ions through graphene oxide membranes
Developing efficient, selective, and scalable separations for critical materials, including lithium and magnesium, is essential to meeting the increasing demands for clean energy technologies and alleviating challenges with domestic supply chains. Gr.....»»
Net effects of man-made nitrogen attenuate global warming, researchers find
Nitrogen fertilizers and nitrogen oxides from fossil fuels are known for their environmental damage: they pollute the air and drinking water, lead to over-fertilization of water and land ecosystems, reduce biodiversity and damage the ozone layer......»»
"Janus" dual-atom catalyst shows enhanced performance for electrocatalytic oxygen reduction and evolution
A research team led by Prof. Yan Wensheng from the University of Science and Technology of China (USTC) has created the innovative "Janus" dual-atom catalyst (FeCo-N3O3@C) with Fe and Co atoms coordinated synergistically through an N-O bridge, which.....»»
How biodiversity is changing in one of the world"s most productive ocean ecosystems
In research published in Global Change Biology, investigators have examined DNA within ocean bottom sediment cores to assess changes in living organisms within one of the world's most productive marine ecosystems: the Atacama Trench in the eastern Pa.....»»
Stress granules found to play an unsuspected role in blood vessel formation
The behavior of the cells that make up our blood vessels is crucial to our well-being. Conditions such as inflammation, oxygen deprivation and viral infection can stress these cells and disrupt the formation of new, often pathological, blood vessels......»»
