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.

A new material developed at the University of Virginia – an oxygen nanosensor that couples a light-emitting dye with a biopolymer – simplifies the imaging of oxygen-deficient regions of tumors. Such tumors are associated with increased cancer aggressiveness and are particularly difficult to treat.

UCD Conway researchers have characterized epigenetic signature changes in prostate cells under conditions of low oxygen levels that may lead to tumor development.

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.

A scientist reported Friday that the Gulf of Mexico's "dead zone," where low amounts of oxygen in the water make it hard for anything to live there, is less than half the size as predicted earlier this year.

Exercise requires the integrated activity of every organ and tissue in the body, and understanding how these respond to the decreased oxygen levels present at moderate to high altitude is the focus of the current special issue of High Altitude Medicine & Biology, a peer-reviewed journal published by Mary Ann Liebert, Inc.

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.

A specific class of drugs could be effective in treating babies vulnerable to sudden infant death syndrome, Canadian researchers suggest. Researchers at McMaster University in Hamilton said when mothers-to-be smoke during pregnancy the exposure of the fetus to nicotine results in its inability to respond to decreases in oxygen -- known as hypoxia -- which may result in a higher incidence of SIDS. In the study involving rats, researchers found the diabetic medication glibenclamide can reverse...
