  • The magnitude of organic carbon burial in lakes and reservoirs is poorly constrained. Here, using a compilation of modern data from the literature and statistical modeling, the authors estimate a global yearly organic carbon burial of 0.15 Pg C in inland waters, of which 40% is stored in reservoirs.

  • Lakes that form in thawing permafrost emit substantial amounts of greenhouse gases to the atmosphere. It emerges that large quantities of carbon can also be stored in sediments at the lake bottoms. See Letter p.452

  • The land–water interface of lakes is highly vegetated and may reverse the global carbon balance of lakes from a net source to a net sink, according to a mass balance and horizontal transport model quantification of lake littoral zones.

  • An analysis of regional variations in global inland water surface area, dissolved CO2 and gas transfer velocity yields a global CO2 evasion rate of 2.1 × 1015 grams of carbon per year, which is higher than previous estimates owing to a larger contribution from streams and rivers.

  • Persistent organic pollutants (POPs) are found in hadal trench sediment in the Atacama trench at depths down to 8085 m. High turnover of organic matter in the trench contributes to elevated contaminant concentrations in this extreme and remote place.

  • The annual burial of organic carbon in lakes and reservoirs exceeds that of ocean sediments, but inland waters are components of the global carbon cycle that receive only limited attention. Here the authors find that the mineralization of organic carbon in lake sediments exhibits a strong positive relationship with temperature, suggesting that warmer water temperatures lead to more mineralization and less organic carbon burial.

  • This study shows that Aβ from transgenic host tissue is able to enter and deposit within wild-type grafts via microglia, thus identifying microglia as carriers of Aβ deposition into previously unaffected brain tissue.
