New research reveals low-oxygen impacts on West Coast groundfish
When low-oxygen "dead zones" began appearing off the Oregon Coast in the early 2000's, photos of the ocean floor revealed bottom-dwelling crabs that could not escape the suffocating conditions and died...
View ArticleOcean 'dead zones' a growing disaster for fish
Falling ocean oxygen levels due to rising temperatures and influence from human activities such as agrochemical use is an increasingly widespread problem. Considering that the sea floors have taken...
View ArticleThe weird ways fire behaves in space (w/ Video)
Light a match on earth and you can expect the flame to shoot up in a tapering bulb. But light that match in space and you might not even recognize the small, blue orb at the tip. That's because fire...
View ArticleSalt-tolerant herb rich in antioxidant compounds
Epidemiological studies have emphasised the importance of eating foods high in antioxidants to reduce the risk of developing cancer and cardiovascular disease, two leading causes of death worldwide....
View ArticleWarmer, lower-oxygen oceans will shift marine habitats
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It's the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest...
View ArticleHow do scientists predict the size of an oceanic 'dead zone'?
Later this month, NOAA will announce its prediction for how big the hypoxic "dead zone" will be in the Gulf of Mexico. This year the forecast will be based on an ensemble that incorporates the results...
View ArticleFish declines linked to effects of excess nutrients on coastal estuaries
A comprehensive study of a major California estuary has documented the links between nutrient runoff from coastal land use, the health of the estuary as a nursery for young fish, and the abundance of...
View ArticleVariations in atmospheric oxygen levels shaped Earth's climate through the ages
Variations in the amount of oxygen in Earth's atmosphere significantly altered global climate throughout the planet's history. Efforts to reconstruct past climates must include this previously...
View ArticleMacroscopic quantum phenomena discovered in ice
(Phys.org)—Scientists have discovered an anomaly in the properties of ice at very cold temperatures near 20 K, which they believe can be explained by the quantum tunneling of multiple protons...
View ArticleSmall oxygen jump helped enable early animals take first breaths
If oxygen was a driver of the early evolution of animals, only a slight bump in oxygen levels facilitated it, according to a multi-institutional research team that includes a Virginia Tech geoscientist.
View ArticleNew probe can monitor shock from hemorrhages without drawing blood
It's inefficient to periodically draw blood from someone's neck to check oxygen levels, especially when that person is in an intensive care unit for massive blood loss. Yet the invasive procedure is...
View ArticleGraphene oxide's secret properties revealed at atomic level
Since its discovery, graphene has captured the attention of scientists and engineers for its many extraordinary properties. But graphene oxide—an oxidized derivative of graphene—largely has been viewed...
View ArticleMouthLab: Patients' vital signs are just a breath away
Engineers and physicians at the Johns Hopkins University School of Medicine have developed a hand-held, battery-powered device that quickly picks up vital signs from a patient's lips and fingertip....
View ArticleAncient dirt churners took their time stirring up the ocean floor
Earth's early burrowers were slow to discover the bottom of the ocean as a good place to kick up dirt.

View ArticleScientists use exhaled breath to detect hypoxia
Researchers working in the United States have demonstrated a technique that may enable real-time, in-flight detection of hypoxia in pilots.
View ArticleGlobal warming disaster could suffocate life on planet Earth, research shows
Falling oxygen levels caused by global warming could be a greater threat to the survival of life on planet Earth than flooding, according to researchers from the University of Leicester.
View ArticleDoomsday revisited: will warming deprive us of oxygen?
Global warming has triggered an array of apocalyptic scenarios for future generations, from worsening drought, storms and floods to melted icesheets and rising seas.
View ArticleLife exploded on Earth after slow rise of oxygen
It took 100 million years for oxygen levels in the oceans and atmosphere to increase to the level that allowed the explosion of animal life on Earth about 600 million years ago, according to a UCL-led...
