Stress Lessons From Yeast
The humble yeast can teach us vital lessons in coping with stress, according to researchers from the University of Newcastle upon Tyne. Speaking tomorrow, Thursday 11 September 2003, at the Society for General Microbiology's meeting at UMIST in Manchester, Dr Jan Quinn will explain how she and colleagues have tracked stress responses in yeast to... view more...

Loose grip
Carbon dioxide (CO2) is contained in the air we exhale, and is also always formed when carbon-containing substances such as oil, gas, wood, and plastics are burned - it is omnipres-ent. Chemists have long been trying to convert this gas to something useful, and Koji Tanaka and coworkers from the Institute for Molecular Science in Myodaiji, Japan,... view more... (1999-01-28)
No oxygen in Eastern Mediterranean bottom-water
Research from Utrecht University shows that there is an organic-rich bed of sediment in the floor of the Eastern Mediterranean. This bed formed over a period of about 4000 years under oxygen-free bottom-water conditions. view more (2008-09-29)
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)
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)
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)
Deep-sea rocks point to early oxygen on Earth
Red jasper cored from layers 3.46 billion years old suggests that not only did the oceans contain abundant oxygen then, but that the atmosphere was as oxygen rich as it is today, according to geologists. view more (2009-03-25)
The Rise of Oxygen Caused Earth's Earliest Ice Age
Geologists may have uncovered the answer to an age-old question - an ice-age-old question, that is. view more (2009-05-07)
A new soldier in the war on cancer: The blind mole rat
If someone ever calls you a "dirty rat," consider it a compliment. A new discovery published online in the FASEB Journal shows that cellular mechanisms used by the blind mole rat to survive the very low oxygen environment of its subterranean niche are the same as those that tumors use to thrive deep in our tissues. view more (2009-03-05)
Anesthesia and Alzheimer's
In studies of human brain cells, the widely-used anesthetic desflurane does not contribute to increased production of amyloid-beta protein; however, when combined with low oxygen conditions, it can produce more of this Alzheimer's associated protein. view more (2008-04-28)
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)
Scientists Discover How Fish Evolved To Float At Different Sea Depths
Scientists at the University of Liverpool have discovered how fish have evolved over the last 400 million years to stay motionless at different water depths. view more (2005-03-18)
A molecular switch turns on the flame in 'nature's blowtorch'
Uncontrolled reaction of organic compounds with oxygen is easy: we call it fire. But nature often needs to do oxidations very specifically, adding oxygen to a particular carbon atom in a complicated molecule without disturbing anything else. view more (2008-05-30)
Cellular organelle evolved repeatedly
NWO researchers have discovered that in the course of evolution hydrogenosomes repeatedly evolved from mitochondria. Hydrogenosomes, or 'hydrogen-forming organelles', are cell organelles that produce hydrogen and energy. They serve as an alternative energy supply in organisms that live without oxygen, such as anaerobic fungi and protozoa. The... view more... (2001-07-26)
Maintaining aerobic fitness could delay biological aging by up to 12 years
Maintaining aerobic fitness through middle age and beyond can delay biological ageing by up to 12 years and prolong independence during old age, concludes an analysis published ahead of print in the British Journal of Sports Medicine. view more (2008-04-10)
Study: Added oxygen during stroke reduces brain tissue damage
Scientists have countered findings of previous clinical trials by showing that giving supplemental oxygen to animals during a stroke can reduce damage to brain tissue surrounding the clot. view more (2009-10-20)
Antioxidant protects against lung damage in silicosis
Levels of heme oxygenase-1 (HO-1), an antioxidant that protects against reactive oxygen species (damaging oxygen molecules that cause direct tissue injury), become elevated in the lungs of chronic silicosis patients and could represent a new treatment approach for the disease. view more (2006-10-16)
Steep oxygen decline halted first land colonization by Earth's sea creatures
Vertebrate creatures first began moving from the world's oceans to land about 415 million years ago, then all but disappeared by 360 million years ago. view more (2006-10-24)
Learning to live with oxygen on early Earth
Washington, D.C. Scientists at the Carnegie Institution and Penn State University have discovered evidence showing that microbes adapted to living with oxygen 2.72 billion years ago, at least 300 million years before the rise of oxygen in the atmosphere. view more (2006-10-17)
Light reveals breast tumor oxygen status
Light directed at a breast tumor through a needle can provide pathologists with biological specifics of the tumor and help oncologists choose treatment options that would be most effective for that individual patient. view more (2009-04-01)
