McMaster researchers have found there is such a thing as too much oxygen for acutely ill adults. Extensive data analyses in a study from the university show that supplemental oxygen, when given liberally to these patients, increases the risk of death without improving other health outcomes. The results were published in The Lancet. “Supplemental oxygen is administered to […]
Several times in the distant past, our home planet has been cleansed of its residents, with the exception of a few plucky survivors. Perhaps the best known and most spectacular extinction was that of the dinosaurs, caused when a meteorite six miles in diameter crashed into Earth about 65 million years ago. There was another […]
UNSW Sydney chemists have invented a new, cheap catalyst for splitting water with an electrical current to efficiently produce clean hydrogen fuel. The technology is based on the creation of ultrathin slices of porous metal-organic complex materials coated onto a foam electrode, which the researchers have unexpectedly shown is highly conductive of electricity and active […]
A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic, conditions that led to vast marine dead zones. Results of the research, which was funded by the National Science Foundation (NSF), are published today in the journalNature. “This […]
