First animals oxygenated the ocean, research suggests
The evolution of the first animals may have oxygenated the earth's oceans – contrary to the traditional view that a rise in oxygen triggered their development.
View ArticleNew material steals oxygen from the air
Researchers from the University of Southern Denmark have synthesized crystalline materials that can bind and store oxygen in high concentrations. Just one spoon of the substance is enough to absorb all...
View ArticleBlue blood on ice: How an Antarctic octopus survives the cold
An Antarctic octopus that lives in ice-cold water uses an unique strategy to transport oxygen in its blood, according to research published in Frontiers in Zoology. The study suggests that the...
View ArticleWarmer, lower-oxygen oceans will shift marine habitats
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It's the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest...
View ArticleMathematics taking guesswork out of plastic surgery tissue transfer
Plastic surgeons are turning to mathematics to take the guesswork out of efforts to ensure that live tissue segments that are selected to restore damaged body parts will have enough blood and oxygen to...
View ArticleCutting off the oxygen supply to serious diseases
A new family of proteins which regulate the human body's 'hypoxic response' to low levels of oxygen has been discovered by scientists at Barts Cancer Institute at Queen Mary, University of London and...

A unmanned Progress spaceship racing to the International Space Station with 2.5 tonnes of cargo on board failed Wednesday to deploy a key antenna that helps it dock with the orbiting lab in the latest...
View ArticleScientists discover new variability in iron supply to the oceans with climate...
The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed – with implications for future climate prediction.
View ArticleCell behaviour in low oxygen conditions mapped
(Phys.org) —Research at the University of Liverpool has explained how cells behave when placed in a low oxygen environment, a development that could have implications for cancer patients and other...
View ArticleBackswimmers use buoyancy aid like a gill
Ever since he can remember, Karl Jones has been fascinated by the animals that live in streams. 'I grew up next to a river in the Adelaide Hills where I spent many hours catching the creatures that...
View ArticleCells starved of oxygen and nutrients condense their DNA
Scientists at the Institute of Molecular Biology (IMB) have been able to see, for the first time, the dramatic changes that occur in the DNA of cells that are starved of oxygen and nutrients. This...
View ArticleWidespread loss of ocean oxygen to become noticeable in 2030s
A reduction in the amount of oxygen dissolved in the oceans due to climate change is already discernible in some parts of the world and should be evident across large regions of the oceans between 2030...
View ArticleAcidification and low oxygen put fish in double jeopardy
Severe oxygen drops in the water can leave trails of fish kills in their wakes, but scientists thought adult fish would be more resilient to the second major threat in coastal waters: acidification. A...

Plastic surgeons are turning to mathematics to take the guesswork out of efforts to ensure that live tissue segments that are selected to restore damaged body parts will have enough blood and oxygen to...
View ArticleBacteria can survive in marine environments that are almost completely...
Around the world, wide swaths of open ocean are nearly depleted of oxygen. Not quite dead zones, they are "oxygen minimum zones," where a confluence of natural processes has led to extremely low...
View ArticleGlobal ocean de-oxygenation quantified
Oxygen is an essential necessity of life on land. The same applies for almost all organisms in the ocean. However, the oxygen supply in the oceans is threatened by global warming in two ways: Warmer...
