The human microbiome is a complex and dynamic system that plays important roles in
human health and disease. However, there remain limitations and theoretical gaps in our …

Depending on cell type, environmental inputs, and disease, the cells in the human body can
have widely different sizes. In recent years, it has become clear that cell size is a major …

Nitrogen (N2) fixation in oligotrophic surface waters is the main source of new nitrogen to the
ocean and has a key role in fuelling the biological carbon pump. Oceanic N2 fixation has …

Heavy metal contamination poses an escalating global challenge to soil ecosystems, with
hyperaccumulators playing a crucial role in environmental remediation and resource …

The high diversity and global distribution of heterotrophic bacterial diazotrophs (HBDs) in
the ocean has recently become apparent. However, understanding the role these largely …

Earth's marine nitrogen cycle has co-evolved with life and redox conditions over geological
time. In this Review, we provide an account of nitrogen cycling in the world's oceans over the …

Nitrogen (N) is a vital nutrient and an essential component of biological macromolecules
such as nucleic acids and proteins. Microorganisms are major drivers of N-cycling …

Eukaryotic cells are notably complex—for example, they have various organelles, which are
membrane-bound structures with specific functions. Two of these organelles, mitochondria …

Abstract The endosymbiont Candidatus Azoamicus ciliaticola was proposed to generate
ATP for its eukaryotic host, an anaerobic ciliate of the Plagiopylea class, fulfilling a function …

Given that crop yields are strongly limited by nitrogen, engineering crop plants with self-
nitrogen-fertilization capacity holds great promise for sustainable agriculture. Recently, a …
