  • Upward fluxes have been thought to dominate nutrient replenishment at the ocean surface. A numerical model reveals that lateral transfer is an important source of phosphorus and nitrogen for all five subtropical gyres.

  • The elemental composition of marine organic matter is used to infer a variety of oceanic ecosystem processes. A compilation of observational data suggests that elemental ratios differ substantially from the Redfield ratio, but exhibit a clear latitudinal trend.

  • By using several decades of hydrographic data and an inverse biogeochemical model that implicitly accounts for all known export pathways, a top-down estimate of the strength of the biological carbon pump is calculated.

  • Convergent estimates of nitrogen fixation from an inverse biogeochemical and a prognostic ocean model show that biological carbon export in the ocean is higher than expected and that stabilizing nitrogen-cycle feedbacks are weaker than we thought.

  • A randomized trial in patients hospitalized with COVID-19 showed no benefit and potentially increased harm associated with the use of convalescent plasma, with subgroup analyses suggesting that the antibody profile in donor plasma is critical in determining clinical outcomes.

  • Modelling of ocean carbon uptake for the 1980s to the 2000s shows that stronger upper-ocean overturning caused less carbon to be absorbed by the oceans in the 1990s, but that as the overturning circulation weakens more carbon is now being absorbed.
