Nitrogen fixation occurs under Arctic sea ice and is positively correlated with primary production, according to analyses of transects across the marginal ice zone and in the Central Arctic Ocean.

Loretan and colleagues present a low-cost smartphone-based microscope capable of detecting single-molecule fluorescence. This approach opens doors to personalised and widely distributed applications in diagnostics, biosensing, and science education.

Biological nitrogen fixation is a key driver of global primary production and climate. Decades of effort have repeatedly updated nitrogen fixation estimates for terrestrial and open ocean systems, yet...

Nature, Published online: 01 April 2025; doi:10.1038/d41586-025-00915-5 Why really good trombones sound the way they do, and the peculiar motion of creatures in the ocean, in this week’s dip into Nature’s archive.

Heterotrophic bacteria fix N2 in more diverse environments than previously thought, critical for the oceanic nitrogen cycle.

We find a diverse and active particle-associated non-cyanobacterial diazotroph community in the mesopelagic zone of the North Pacific Gyre, suggesting a significant contribution to pelagic nitrogen fi...

Vertical migrations by marine organisms contribute to carbon export by consumption of surface phytoplankton followed by defecation in the deep ocean. However, biogeochemical models lack observational ...

La neige se pare parfois de couleurs originales… et le plus intrigant, c’est que la neige rouge sang accueille des algues qui favorisent la biodiversité dans ce milieu que l’on croit si « vierge ».
