A new study from the University of Helsinki reveals how plant mitochondria draw molecular oxygen away from chloroplasts, an interaction not previously documented. The discovery sheds new light on how ...

Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that ...

Ancient microbes tied to our earliest ancestors could use oxygen, reshaping ideas about how complex life began on Earth.

Our well-worn textbooks might have us believe that the rise of atmospheric oxygen some 2.45 billion years ago --- to levels making complex life tenable over large swaths of this pale blue dot --- is a ...
