The parents of a boy killed in January in a fiery explosion inside a hyperbaric oxygen chamber filed a lawsuit Monday, alleging the 5-year-old perished as a result of “corporate greed.” The suit filed in Oakland County circuit court in Michigan calls Thomas Cooper’s death the result of “callous indifference to human life” by the manufacturer of the oxygen chamber …

Earth wouldn’t be the lively place it is without photosynthesis, which harnesses solar energy to fuel most of the planet’s food webs. A variety of plants, algae, and cyanobacteria provide this service, but few do it quite like Prochlorococcus, considered to be Earth’s most abundant photosynthetic organism. Tiny even for cyanobacteria, this marine microbe wields outsized influence in its habitats …

Spacecraft are equipped with Environmental Control and Life Support Systems (ECLSS), which regulate atmospheric pressure, temperature, humidity, and provide oxygen. These systems use technologies like water electrolysis to generate oxygen and remove carbon dioxide from the cabin air. Backup systems, such as emergency oxygen tanks, are also available to ensure a continuous supply of breathable air. Source link

Extremophiles are a favorite tool of astrobiologists. But not only are they good for understanding the kinds of extreme environments that life can survive in, sometimes they are useful as actual tools, creating materials necessary for other life – like oxygen – in those extreme environments. A recent paper from Daniella Billi of the University of Rome Tor Vergata, published …

Ever since its formation around 4.5 billion years ago, Earth’s rotation has been gradually slowing down, and its days have gotten progressively longer as a result. While Earth’s slowdown is not noticeable on human timescales, it’s enough to work significant changes over eons. One of those changes is perhaps the most significant of all, at least to us: lengthening days …

Recent studies have revealed fascinating connections between rising oxygen levels in deep-ocean environments and the evolution of marine life, particularly in the Late Devonian period. This research, published in the Proceedings of the National Academy of Sciences, uncovers how oxygenation, driven by terrestrial plant growth, may have shaped the future of life in the ocean. These findings help us understand …

A team of scientists from Korea and Japan has discovered a new type of crystal that can “breathe” — releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices. The newly developed material is a special kind of metal oxide …

A monster galaxy from the early universe shows that the cosmos was rich with oxygen when it was only less than 3% of its present age, astronomers have found. The discovery raises questions about how early life could have first appeared in the universe. This isn’t the first time astronomers have looked at that enigmatic galaxy, named JADES-GS-z11-0. It was …

Last week, when Apple announced the release of a “redesigned Blood Oxygen feature” to the Apple Watch, many figured Masimo (who had been suing Apple over patents related to the feature), would look for a way to fight back. Today, the company did just that and filed a new lawsuit. But this time, it’s against the US Customs and Border …

US Customs and Border Protection unlawfully let Apple Inc. reactivate a blood-oxygen tracking feature on Apple Watches that infringes patents for the technology, Masimo Corp. said in a federal lawsuit. CBP exceeded its authority in an Aug. 1 internal advice ruling that overturned its own January decision without notice or input from Masimo, the medical-device maker said in a complaint …
