How fish species suffer as a result of warmer waters
Ongoing global climate change causes changes in the species composition of marine ecosystems, especially in shallow coastal oceans. view more (2007-01-05)
Alligator egg development at prehistoric oxygen levels
The development of bone structures in alligator eggs raised under varying oxygen concentrations creates a link to fossil records of the evolution of vertebrates and prehistoric atmospheric oxygen concentrations, according to a paper to be presented at the Earth System Processes 2 meeting in Alberta, Canada. view more (2005-08-05)
Climate change and the rise of atmospheric oxygen
Today's climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. view more (2006-03-23)
Why are so many people dying on Everest?
It used to be thought that it would be physiologically impossible to climb Mount Everest with or without oxygen. In 1953 Hillary and Tenzing proved that it was possible to reach the summit with oxygen and in 1978 Messner and Habeler demonstrated it was possible without oxygen. view more (2006-08-25)
Does life exist on other planets?
Recent research argues that an atmosphere rich in oxygen is the most likely source of energy for complex life to exist anywhere in the Universe, thereby limiting the number of places life may exist. view more (2005-06-20)
Higher nitric oxide levels increase survival in ALI/ARDS trial
In a large-scale, multi-center trial of patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS), researchers showed that higher levels of nitric oxide (NO) in patient urine were strongly associated with improved survival, more ventilator-free days, and decreased rates of organ failure. view more (2007-02-01)
Rising ocean temperatures, pollution have oysters in hot water
Oysters exposed to high water temperatures and a common heavy metal are unable to obtain sufficient oxygen and convert it to cellular energy. view more (2006-10-11)
Genetically engineered blood protein can be used to split water into oxygen and hydrogen
Scientists have combined two molecules that occur naturally in blood to engineer a molecular complex that uses solar energy to split water into hydrogen and oxygen. view more (2006-12-01)
Helium helps patients breathe easier
It makes for bobbing balloons and squeaky voices, but now helium is also helping people with severe respiratory problems breathe easier. view more (2007-02-02)
Alloy of hydrogen and oxygen made from water
Water, the only indispensable ingredient of life, is just about the most versatile stuff on Earth. Depending on its temperature we can heat our homes with it, bathe in it, and even strap on skates and glide across it, to name only the most common of its many forms. When subjected to high pressures, however, water can take any of more than 15... view more... (2006-10-27)
Marijuana compound may help stop diabetic retinopathy
A compound found in marijuana won't make you high but it may help keep your eyes healthy if you're a diabetic, researchers say. view more (2006-02-28)
Penn study finds hyperbaric oxygen treatments mobilize stem cells
According to a study to be published in the American Journal of Physiology-Heart and Circulation Physiology, a typical course of hyperbaric oxygen treatments increases by eight-fold the number of stem cells circulating in a patient's body. view more (2005-12-29)
Diabetic hearts make unhealthy switch to high-fat diet
The high-fat "diet" that diabetic heart muscle consumes helps make cardiovascular disease the most common killer of diabetic patients, according to a study done at Washington University School of Medicine in St. Louis. view more (2006-02-06)
The presence of oxygen on carbon nanotubes enhances interaction with ammonia
Single-walled carbon nanotubes (SWNTs), which could play an important role in developing sensors against chemical threats, have enhanced interaction with ammonia because of the presence of oxygen groups on the nanotubes, researchers at Temple University have discovered. view more (2005-07-12)
Lactic acid not athlete's poison, but an energy source-if you know how to use it
In the lore of marathoners and extreme athletes, lactic acid is poison, a waste product that builds up in the muscles and leads to muscle fatigue, reduced performance and pain. view more (2006-04-20)
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)
Prenatal nicotine exposure reduces breathing response of newborns
Exposure to nicotine the equivalent of smoking two packs of cigarets a day produced complicated, abnormal breathing development during the first 18 days of newborn rats, University of Arizona researchers report. view more (2006-04-06)
As ozone hole approaches annual peak, NASA scientists reveal latest information and images
In 1987, the United States joined several other nations in signing the Montreal Protocol, an international treaty designed to protect the Earth's ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. view more (2006-09-29)
Study shows our ancestors survived 'Snowball Earth'
It has been 2.3 billion years since Earth's atmosphere became infused with enough oxygen to support life as we know it. About the same time, the planet became encased in ice that some scientists speculate was more than a half-mile deep. view more (2006-06-07)
Second low-oxygen pathway hints at cancer, cardiovascular disease physiology
Researchers at the University of Pennsylvania School of Medicine have identified a second molecular pathway that promotes cell survival in low-oxygen conditions. view more (2006-02-17)
