The fluxes used in this global summary are largely those deduced within each of the sectors (terrestrial, marine, etc.) presented in the companion papers. 2. Sources of fixed nitrogen (a) Biological fixation (i) Terrestrial ecosystems BNF provides an important reference when quantifying the import...
The impacts of enhanced nitrogen (N) deposition on the global forest carbon (C) sink and other ecosystem services may depend on whether N is deposited in reduced (mainly as ammonium) or oxidized forms (mainly as nitrate) and the subsequent fate of each. However, the fates of the two key...
In summary, we argue that our carbon isotope curve from the middle Kunae to the uppermost Carlottense Zone does show similarities with other carbon isotope curves from North-western European sections. Nevertheless, the global extent of these variations is still debatable since in carbon isotope ...
Ca. T. diatomicola has a strongly reduced genome size, but the genome still encodes core carbon-processing pathways such as glycolysis and the tricarboxylic acid (TCA) cycle, which are present in many heterotrophic bacteria. However, on the basis of the low transcription of glycolysis genes (Su...

2022). However, the comparison between Venus and Earth is complicated by the fact that the nitrogen cycle is modulated by Earth’s biosphere (Jacob 1999; Zerkle and Mikhail 2017). Sulfur dioxide is the third most abundant gas in the atmosphere of Venus. In contrast to N2, SO2 is extremely...
Dual-atom catalysts, particularly those with heteronuclear active sites, have the potential to outperform the well-established single-atom catalysts for oxygen evolution reaction, but the underlying mechanistic understanding is still lacking. Herein, a l
Accordingly, blocking either FASN or the Lands cycle in KMLC, promotes ferroptosis, a reactive oxygen species (ROS)- and iron-dependent cell death, characterized by the intracellular accumulation of oxidation-prone PC. Our work indicates that KM dictates a dependency on newly synthesized FA to ...
In summary, a general methodology for the ultra-high-throughput ee determination and asymmetric reaction screening was developed by combing the diastereoisomerization strategy and IM-MS analysis in this study. Compare with traditional methods, the workflow proposed in this study trades a convenient post...
(ETSP) OMZ waters, assessing whether OMZ viruses might impact nitrogen (N) cycling via AMGs. Identified viral genomes encoded six N-cycle AMGs associated with denitrification, nitrification, assimilatory nitrate reduction, and nitrite transport. The majority of these AMGs (80%) were identified in...
