A study has revealed that grey seals can monitor their blood oxygen levels to determine when they need to surface for air. Researchers tested seals in controlled environments, exposing them to different oxygen and carbon dioxide levels. The findings confirmed that higher oxygen led to longer dives, while reduced oxygen shortened them. Surprisingly, increased carbon di...

Although he is no longer in critical condition, the 88-year-old pontiff still receives respiratory assistance through a nasal cannula during the day and an oxygen mask at night.

A new study suggests water formed in the universe just 100–200 million years after the Big Bang, much earlier than previously estimated. Researchers examined ancient supernovas to understand how oxygen combined with hydrogen to create water. If confirmed, these findings could change perspectives on when the conditions for life first emerged. The study indicates that...
