Study shows continued spread of 'dead zones'
A global study led by Professor Robert Diaz of the Virginia Institute of Marine Science, College of William and Mary, shows that the number of "dead zones"-areas of seafloor with too little oxygen for most marine life-has increased by a third between 1995 and 2007.   view more (2008-08-15)

NOAA and Louisiana scientists predict largest Gulf of Mexico 'dead zone' on record
NOAA-supported scientists from the Louisiana Universities Marine Consortium and Louisiana State University are forecasting that the "dead zone" off the coast of Louisiana and Texas in the Gulf of Mexico this summer could be the largest on record.   view more (2008-07-16)

Resuscitation technique after brain injury may do more harm than good
The current standard practice of giving infants and children 100 percent oxygen to prevent brain damage caused by oxygen deprivation may actually inflict additional harm, researchers at UT Southwestern Medical Center have found.   view more (2008-07-01)

New therapy shows promise for fighting treatment-resistant cancer cells
A gene radiotherapy system that detects and treats cancer cells that are resistant to traditional forms of chemotherapy and radiation showed success in the laboratory and could eventually prove beneficial for cancer patients, according to researchers at SNM's 55th Annual Meeting.   view more (2008-06-17)

Smoking during pregnancy increases risk of SIDS
A new study provides the most direct evidence that there exists a causal link between smoking during pregnancy and Sudden Infant Death Syndrome (SIDS).   view more (2008-05-30)

Hypoxia training suppresses harmful cardiac nitric oxide production during heart attack
Researchers at the University of North Texas Health Science Center, Fort Worth, Texas have demonstrated that, contrary to prevailing dogma, hypoxia can be remarkably beneficial to the heart. These discoveries, to be reported in the June 2008 issue of Experimental Biology and Medicine, may lead to a... view more (2008-05-27)

A new gene trigger for pregnancy disorder identified
The COMT gene - known already for its role in schizophrenia - has been found to play a role in preeclampsia, according to a report in today's advance on-line issue of Nature.   view more (2008-05-12)

Researchers link master regulator of innate immunity to the hypoxic response
Survival of all animals depends on their ability to withstand microbial infections and adapt to fluctuations in oxygen concentrations.   view more (2008-04-24)

Adaptive functional evolution of leptin in cold-adaptive pika family
Researchers at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences have put forward the viewpoint for the first time that adaptive functional evolution may occur in the leptin protein of the pika (Ochotona) family, a typical cold-adaptive mammal.   view more (2008-01-23)

Better access to cool caps improves outcomes, lowers cost of treating asphyxia in newborns
When newborns suffering from a form of asphyxia at birth have better access to head cooling devices, fewer will face a lifetime of debilitating and costly health complications, according to researchers at Beth Israel Deaconess Medical Center (BIDMC).   view more (2008-01-08)

FOXO factor promotes survival of oxygen-deprived cancer cells
Scientists report that an evolutionarily conserved transcription factor may have both positive and negative effects on the growth of tumors, depending on whether or not the tumor cells have enough oxygen.   view more (2007-12-28)

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)

A new chemotherapeutic target for hepatocellular carcinoma
Hepatocellular carcinoma (HCC) is a major health problem worldwide. Currently, the only chance for obtaining a cure in patients with HCC is by either a surgical resection or liver transplantation.   view more (2007-10-25)

Low oxygen in coastal waters impairs fish reproduction
Low oxygen levels in coastal waters interfere with fish reproduction by disrupting the fishes' hormones, a marine scientist from The University of Texas at Austin Marine Science Institute has found.   view more (2007-08-29)

Alternative farming cleans up water
Although the addition of nutrients to soil helps to maximize crop production, fertilizer can leach nutrients, polluting the water supply.   view more (2007-07-20)

Hearts of male and female rainbow trout are different
The heart is one of the most energy demanding organs of the human body. Its failure to function properly accounts for 600,000 deaths each year. Similarly, the rainbow trout, native to the Pacific Northwest and beloved as a sport- and food fish, requires dynamic and sustained cardiac function to... view more (2007-04-30)

Deadly hypoxic event finally concludes
The longest, largest and most devastating hypoxic event ever observed in marine waters off the Oregon Coast has finally ended.   view more (2006-10-31)

Seals protect brain, conserve oxygen by turning off shivering response on icy dives
Seals shiver when exposed to cold air but not when diving in chilly water, a finding that researchers believe allows the diving seal to conserve oxygen and minimize brain damage that could result from long dives.   view more (2006-10-10)

Oxygen deprived brains repaired and saved
Scientists from Melbourne's Howard Florey Institute have found special proteins that protect the brain after it has been damaged by a lack of oxygen, which occurs in conditions such as stroke, perinatal asphyxia, near-drowning and traumatic brain injury.   view more (2006-08-25)

'Dead Zone' causing wave of death off Oregon coast
The most severe low-oxygen ocean conditions ever observed on the West Coast of the United States have turned parts of the seafloor off Oregon into a carpet of dead Dungeness crabs and rotting sea worms, a new survey shows. Virtually all of the fish appear to have fled the area.   view more (2006-08-11)

Marine 'dead zone' off Oregon is spreading
A hypoxic "dead zone" has formed off the Oregon Coast for the fifth time in five years, according to researchers at Oregon State University.   view more (2006-07-28)

New tool tracks brain development in babies
Researchers have used a new technique to monitor brain development in infants and detect disturbances in white matter, according to a study in the July issue of Radiology.   view more (2006-06-27)

Stanford scientists identify protein involved in fast-spreading cancers
Researchers at the Stanford University School of Medicine have found a protein that may explain why tumors in a low-oxygen environment are more deadly.   view more (2006-04-27)

Ocean 'dead zones' trigger sex changes in fish, posing extinction threat
Oxygen depletion in the world's oceans, primarily caused by agricultural run-off and pollution, could spark the development of far more male fish than female, thereby threatening some species with extinction.   view more (2006-03-30)

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)
