A man in his 40s consumed a "carnivore diet" for eight months and then developed yellow bumps on his hands, feet and elbows ...

A flurry of criticism followed the article’s publication, including from the deep-sea mining company that funded the study, ...

Certain metallic rocks seem to be making oxygen in the dark, without light or sunshine, at the bottom of the ocean.

Plants with root nodules, for example, secrete compounds such as flavonoids when nitrates are scarce in the soil, helping to activate signaling pathways in nitrogen-fixing bacteria that then ...

Root nodules are organs on plant roots that facilitate the symbiotic relationship. Rhizobia colonize these nodules and fix nitrogen by converting nitrogen from air into ammonia. Iron is needed for ...

The shock discovery that metallic nodules could be producing oxygen in the deep sea made headlines last year – now the team ...

The key to their success is a type of bacteria called rhizobia, which lives inside nodules, or the little nubs you sometimes see on plant roots. While we usually think of bacteria as dangerous ...

The equilibrium: hæmoglobin ⇄ methæmoglobin in the root nodules depends decisively on the intensity of light and on the stage of growth of the plants. The root nodules of vigorously growing ...
