Nitrogen fixation under declining Arctic sea ice - Communications Earth & Environment 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.

So cool to see this one out!! www.nature.com/articles/s43...

Direct single-molecule detection and super-resolution imaging with a low-cost portable smartphone-based microscope - Nature Communications 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.

This is figure 1, which gives an overview of the methods used to generate artificial mimetic stimuli.

Birds have an excellent ability to learn to discriminate harmless insects from those that they mimic on the basis of subtle differences in appearance, according to a study in Nature. go.nature.com/44yj4M5 🧪

Global importance of nitrogen fixation across inland and coastal waters 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...

Glad to share our paper revealing that inland and coastal waters, while covering <10% of Earth’s surface, contribute ~20% of global nitrogen fixation! www.science.org/doi/10.1126/... @noc.ac.uk @ird-fr.bsky.social @mioceanologie.bsky.social

Dynamics of diazotroph particle colonization in the Arctic Ocean

Really proud of @arthurcoet.bsky.social for his fantastic first first-author paper about particle colonisation by diazotrophs in the #Arctic in @isme-microbes.bsky.social academic.oup.com/ismej/advanc...
