'Hot' oxygen atoms on titanium dioxide motivated by more than just temperature
Like two ballroom dancers waltzing together, the two atoms of an oxygen molecule severed by a metal catalyst usually behave identically. But new research reveals that on a particular catalyst, split oxygen atoms act like a couple dancing the tango: one oxygen atom plants itself while the other shimmies away, probably with energy partially stolen... view more...

Damage from oxygen may be one cause of Parkinson's disease
Research by neuroscientists at the University of Virginia Health System shows that oxygen free radicals are damaging proteins in mitochondria, the tiny cellular 'batteries' of brain cells. view more (2006-05-17)
Drops in blood oxygen levels may be key to sudden death in some epilepsy patients
A new study by researchers at UC Davis Medical Center suggests that the sudden unexplained deaths of some epilepsy patients may be a result of their brains not telling their bodies to breathe during seizures. view more (2008-11-18)
Research advances understanding of how hydrogen fuel is made
Oxygen may be necessary for life, but it sure gets in the way of making hydrogen fuel cheaply and abundantly from a family of enzymes present in many microorganisms. view more (2005-10-06)
Adaptation to oxygen deprivation elucidates tumor physiology
Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand. view more (2006-03-08)
How rusty is the Earth?
An iron object lying around outside quickly turns rusty. Iron metal always has to be combined with some other elements or coated with paint to stop it corroding. The reason for this is that iron metal is unstable in the presence of the oxygen in the Earth's atmosphere. It reacts with the iron to produce ferric iron, a form of iron that exists in... view more... (2004-06-10)
Finding an answer to Darwin's Dilemma
The sudden appearance of large animal fossils more than 500 million years ago - a problem that perplexed even Charles Darwin and is commonly known as "Darwin's Dilemma" - may be due to a huge increase of oxygen in the world's oceans, says Queen's paleontologist Guy Narbonne, an expert in the early evolution of animals and their... view more...

Researchers detect hint of oxygen 50 to 100 million years earlier than first believed
Two teams of scientists, including three researchers from UC Riverside, report that traces of oxygen appeared in Earth's atmosphere roughly 100 million years before the "Great Oxidation Event" 2.4 billion years ago. view more (2007-09-28)
Model gives clearer idea of how oxygen came to dominate Earth's atmosphere
A number of hypotheses have been used to explain how free oxygen first accumulated in Earth's atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. view more (2005-08-09)
Chemistry & Industry - 1 October Issue
NEWS Unexplained miscarriages could be linked to insulin resistance (page 5) Insulin resistance could explain why some women suffer from repeated miscarriage. The association of insulin resistance with repeated pregnancy loss in diabetics and women with polycystic ovary syndrome are well known, but this is the first time its effect on pregnancy... view more...

Reactive oxygen species shown essential for development of inner ear's balance machinery
Reactive oxygen species (ROS) are normally produced as a product of metabolism, and, as their name implies, they are highly reactive with surrounding biological components. view more (2006-01-24)
Towards the mechanism of cell respiration
Researchers at the Institute of Biotechnology of the University of Helsinki have for the first time identified an internal electron transfer reaction that initiates the proton pump mechanism of the respiratory enzyme. view more (2006-04-06)
Red-eyed treefrog embryos actively avoid asphyxiation inside their eggs
Boston University undergraduate Jessica Rogge and associate professor Karen Warkentin, working at the Smithsonian Tropical Research Institute's laboratories in Gamboa, Panama, discovered that frog embryos at a very early developmental stage actively respond to oxygen levels in the egg-as reported in the Nov. 7, 2008 issue of the Journal of... view more...

Using microbes to fuel the US hydrogen economy
The focus on hydrogen as a future fuel source is compelling given dwindling supplies of oil and natural gas, as well as escalating costs and the fact that burning fossil fuels releases large amounts of carbon dioxide, a "greenhouse" gas, into the atmosphere. view more (2006-09-13)
Carbon monoxide protects lung cells against oxygen-induced damage
Researchers at the University of Pittsburgh have demonstrated that low-dose carbon monoxide administered in conjunction with oxygen therapy markedly inhibits oxygen-induced damage to lung cells. view more (2007-01-19)
University of Copenhagen
Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. In shallow coastal regions, these zones can be caused by runoff of excess fertilizers from farming. view more (2009-01-26)
A new link between nickel, methane gas and the evolution of complex life forms on Earth
A University of Alberta researcher is lead author on a paper that reaches back billions of years to establish a new link between nickel, methane gas and the evolution of complex life forms on Earth. view more (2009-04-09)
Food source threatened by carbon dioxide
Carbon dioxide increasing in the atmosphere may affect the microbial life in the sea, which could have an impact on a major food source, warned Dr Ian Joint at a Science Media Centre press briefing today. view more (2007-12-11)
Being overweight super-sizes both risk and consequences of sleep-disordered breathing
Overweight individuals are not just at greater risk of having sleep-disordered-breathing (SDB), they are also likely to suffer greater consequences, according to new research. view more (2009-10-08)
Link between chronic kidney disease and oxygen-deprived tissue
Researchers at the University of Pennsylvania School of Medicine have discovered how low-oxygen conditions can worsen chronic kidney disease (CKD). view more (2007-12-19)
