TL;DR: Rising atmospheric carbon dioxide is expected to cause a large carbon sink in land ecosystems, partly mitigating human-driven climate change and increasing biological nitrogen fixation with rising C a has been observed.

TL;DR: Studies are presented to show that the formation of albumin-bound homocysteine proceeds through the generation of an albumin thiolate anion, and using an in vitro model system to study the mechanisms of this disulfide bond formation, it is shown that homocystine binds to albumin in two steps.

TL;DR: Inductively coupled plasma mass spectrometers (ICPMS), particularly with sector field mass analyzers, has emerged in the past several years as an excellent analytical technique for rapid, highly sensitive determination of transuranic elements (TRU) in environmental samples.

TL;DR: In this paper, the effect of nutrient enrichment on mangrove sediment accretion and carbon accumulation rates is poorly understood, and the authors quantify sediment accumulation through radionuclide tracers to determine organic carbon (OC), total nitrogen (TN), and total phosphorus (TP) accumulation rates during the previous 60 years in both a nutrient-enriched and a pristine forest within the same geomorphological region of southeastern Brazil.

TL;DR: This study demonstrates that ICPMS has considerable potential for rapid determination of the chronology of post-1950 sediments, and also for validating (210)Pb dates where chronologies over longer time-scales are needed.
