Biologists ID molecular basis of high-altitude adaptation in mice
Biologists have long known how adaptive evolution works. New mutations arise within a population and those that confer some benefits to the organism increase in frequency and eventually become fixed in the population. view more (2009-08-11)
New groundbreaking treatment for oxygen-deprived newborns
Until now immediate cooling of the newborn infant was the only treatment that could possibly prevent brain damage following oxygen deprivation during delivery. view more (2009-08-11)
Unraveling how cells respond to low oxygen
Gary Chiang, Ph.D., and colleagues at Burnham Institute for Medical Research (Burnham) have elucidated how the stability of the REDD1 protein is regulated. view more (2009-08-06)
Experimental treatment halts hypoxic-ischemic brain injury in newborns
Inhibiting an enzyme in the brains of newborns suffering from oxygen and blood flow deprivation stops a type of brain damage that is a leading cause of cerebral palsy, mental retardation and death, according to researchers at Cincinnati Children's Hospital Medical Center. view more (2009-07-29)
U-M researcher and colleagues predict large 2009 Gulf of Mexico 'dead zone'; Chesapeake Bay's oxygen-starved zone likely to shrink
University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year's Gulf of Mexico "dead zone" could be one of the largest on record, continuing a decades-long trend that threatens the health of a half-billion-dollar fishery. view more (2009-06-19)
NOAA Forecast Predicts Large
A team of NOAA-supported scientists from the Louisiana Universities Marine Consortium, Louisiana State University, and the University of Michigan is forecasting that the "dead zone" off the coast of Louisiana and Texas in the Gulf of Mexico this summer could be one of the largest on record. view more (2009-06-19)
Study: Why Some Prostate Cancer Returns
The majority of men who receive one of the standard treatments for localized prostate cancer - surgery or radiation therapy - have an excellent outcome. view more (2009-05-28)
Long-term study shows low oxygen levels in prostate tumors can predict recurrence
Fox Chase Cancer Center researchers have discovered that low-oxygen regions in prostate tumors can be used to predict a rise in prostate-specific antigen (PSA) levels, a marker of tumor recurrence in prostate cancer. view more (2009-05-18)
Cell's split personality is a major discovery into neurological diseases
Researchers at the Université de Montreal (UdeM) and the Montreal Neurological Institute (MNI), McGill University have discovered that cells which normally support nerve cell (neuron) survival also play an active and major role in the death of neurons in the eye. view more (2009-05-08)
U of I study shows benefits of hormone found in fat tissue
It's called the obesity paradox. Although obese people are more apt to suffer from inflammatory diseases, such as diabetes, heart disease, and stroke, they are also more likely to survive a major attack caused by one of those conditions. view more (2009-02-27)
Stanford study prevents pancreatic tumor growth in mice by inhibiting key protein
Researchers at Stanford University School of Medicine have identified a protein critical for the growth of pancreatic cancer. view more (2009-02-02)
Repeat C-section before 39 weeks raises risk of neonatal illness
Women choosing repeat cesarean deliveries and having them at term but before completing 39 weeks gestation are up to two times more likely to have a baby with serious complications including respiratory distress resulting in mechanical ventilation and NICU admission. view more (2009-01-08)
Researchers identify genetic switch critical for cell survival in hypoxia
Researchers at the University of California, San Diego School of Medicine have identified a critical metabolic "switch" in fruit flies that helps oxygen-deprived cells survive. view more (2008-10-17)
Brown Scientist Finds Coastal Dead Zones May Benefit Some Species
Coastal dead zones, an increasing concern to ecologists, the fishing industry and the public, may not be as devoid of life after all. A Brown scientist has found that dead zones do indeed support marine life, and that at least one commercially valuable clam actually benefits from oxygen-depleted waters. view more (2008-10-15)
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

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 new paradigm to protect hearts of patients at... view more... (2008-05-27)
