Less oxygen means shorter time between molts, which means shorter life-span, which means fewer hungry grasshoppers. And for farmers, that’s very good news. A recent study offers insight into the relationship between respiratory function and molting that could help farmers save more of their crops. Continue reading

All forms of life that breathe oxygen — even ones that can’t be seen with the naked eye, such as bacteria — must fight oxidants to live. But neutralizing environmental oxidants such as superoxide was a worry only for organisms that dwell in sunlight … Continue reading

Astronomers have now demonstrated that with the advanced technology available in the next decade we should be able to detect biomarkers like oxygen and methane in the planets that orbit dead stars called “white dwarfs” — and to find new forms of life … Continue reading

Organic carbon in runoff from urbanized landscapes is more likely to persist as it is carried downstream, thus contributing to low-oxygen “dead zones” in coastal waters. Continue reading

Scientists have decoded the genome of the western painted turtle, one of the most abundant turtles on Earth, finding clues to their longevity and ability to survive without oxygen during long winters spent hibernating in ice-covered ponds. Continue reading

Scientists have found that a product resulting from a metabolized omega-3 fatty acid helps combat cancer by cutting off the supply of oxygen and nutrients that fuel tumor growth and spread of the disease. Continue reading

Beneath the ocean floor is a desolate place with no oxygen and sunlight. Yet microbes have thrived in this environment for millions of years. Scientists have puzzled over how these microbes survive, but today there are more answers. Continue reading

When babies are deprived of oxygen before birth, brain damage can occur. Preventive treatment is not always available in developing nations. Students have invented a low-tech $40 unit to provide protective cooling in the absence of modern hospital equi… Continue reading

Biogeochemists have filled in a billion-year gap in our understanding of conditions in the early ocean during a critical time in life’s history on Earth. During the period 1.8 to 0.8 billion years ago, oxygen likely remained low in the atmosphere and o… Continue reading

Astronomers have made the most detailed examination yet of the atmosphere of a Jupiter-like planet beyond our Solar System. A spectrum reveals that the carbon to oxygen ratio is consistent with the core accretion scenario, the model thought to explain … Continue reading

Life as we know it is based upon the elements of carbon and oxygen. Now a team of physicists is looking at the conditions necessary to the formation of those two elements in the universe. They’ve found that when it comes to supporting life, the univers… Continue reading

An analysis of a rock sample collected by NASA’s Curiosity rover shows ancient Mars could have supported living microbes. Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon — some of the key chemical ingredients for life -… Continue reading

An air-breathing bio-battery has been constructed by researchers from Poland. The core element providing the new power source with relatively high voltage and long lifetime is a carefully designed cathode taking up oxygen from air and composed of an en… Continue reading

Eighth graders know humans take in oxygen and breath out carbon dioxide. That means cyclists (breathing hard) should pay taxes, right? Uh, wrong. Continue reading

The mammalian placenta is more than just a filter through which nutrition and oxygen are passed from a mother to her unborn child. According to a new study, if a mother is exposed to stress during pregnancy, her placenta translates that experience to h… Continue reading

A new model suggests that inhospitable hydrodgen-sulfide rich waters could have delayed the spread of complex life forms in ancient oceans. The research considers the composition of the oceans 550-700 million years ago and shows that oxygen-poor toxic … Continue reading

Particles from the upper atmosphere trapped in a deep pile of Antarctic snow hold clear chemical traces of global meteorological events, climate scientists from France have found. Anomalies in oxygen found in sulfate particles coincide with several epi… Continue reading

Even dying stars could host planets with life — and if such life exists, we might be able to detect it within the next decade. This encouraging result comes from a new theoretical study of Earth-like planets orbiting white dwarf stars. Researchers fou… Continue reading
