Summary: Microbial production of natural gas in subsurface reservoirs can be enhanced by introducing amendments to stimulate microbial communities. This study shows that deuterated water can be used as a quantitative tracer of stimulated coal-associated methanogenic activity. Field-scale applications of this tracer could be beneficial for other subsurface microbial activities.

Summary: Characterising methane (CH4) sources and their stable isotope values at the regional level is crucial for effective mitigation and accurate atmospheric budgeting. In this study, dual stable isotope analysis was conducted in North-West England to differentiate between emission sources, highlighting the complexity of isoscapes in regions with multiple sources. The findings demonstrated the value of dual-isotope measurements in source attribution and the presence of gas leaks and landfills as emission sources.

Summary: Silver-catalyzed deuteration of nitroaromatics was achieved using D2O as the deuterium source. Unlike traditional directing group-guided hydrogen-isotope exchange, this protocol exhibited an interesting deuteration pattern, with significant deuterium accumulation around the aromatic rings. Additional experiments suggested that the deuteration was initiated by silver-promoted C-H activation. Therefore, a tentative two-stage deuteration mechanism involving aryl-silver species was proposed to explain the deuteration at meta- and para-positions.

Summary: Different metals have significant effects on the microbial composition of chironomid larvae, with specific genera increasing in abundance in the presence of copper or hexavalent chromium. The change in larval microbiota composition is rapid and metal-specific, suggesting that each larva hosts a consortium of bacterial species that can proliferate under specific environmental changes.

Summary: A visible-light-enabled, photocatalyst-free conjugate addition reaction of dehydroamino acids using 4-acyl-1,4-dihydropyridines as both a radical reservoir and reductant has been successfully developed. Various beta-acyl alpha-amino acids and their deuterated analogues were obtained in good results. This method features mild conditions and efficient derivatization, providing a new pathway for the synthesis of unnatural amino acid derivatives.

Summary: Environmentally friendly and highly efficient synthesis of alpha-deuterated amines is achieved via a concise electrochemical process using D2O as deuterium source without any external reductants or catalysts. Various imines are compatible, affording the desired products in high yields and D-incorporation. Gram-scale synthesis and flow-cell electrochemistry technology are used to synthesize deuterated pharmaceutical amines and their intermediates. Mechanistic studies reveal a plausible process, including the formation of carbanion species followed by deuterium atom transfer.

Summary: EUROFER97 steel samples were exposed to deuterium plasma in the PISCES-A linear plasma device. RBS analysis showed enrichment of tungsten and tantalum in the uppermost surface layers. Deuterium depth profiles were measured using the energy-scanning NRA technique, with the deuterium concentration decreasing with increasing exposure temperature.

Summary: Preparation of deuterium incorporated cellulose is important for investigating cellulose internal structure and expanding its application fields. The study successfully prepared cellulosic cotton fibers with anti-rehydration deuterium incorporation and characterized the process using nuclear magnetic resonance and spectroscopy. The results showed that the hydrogen-deuterium exchange occurred preferentially in the amorphous cellulose component and increased treatment time led to higher deuterium incorporation. Additionally, the isotope effect did not affect the cellulose microstructure, crystalline index, or degree of polymerization properties significantly.

Summary: This study aimed to evaluate the impact of deuterium on thyroid hormone synthesis and secretion, as well as the role of Na+/I- symporter (NIS) in altered thyroid function. The results showed that the thyroid gland had a rapid response to shifts in deuterium/protium balance, while the thyroid and pituitary glands had different responses. Furthermore, deuterium blood/tissue and cytosol/organelle gradients may affect the production rate of thyroid hormones independently of the NIS.

Summary: This paper investigates the permeation rate of gaseous hydrogen through a double-layer membrane at 400 degrees C. Exposure of tungsten films to pure oxygen resulted in a noticeable decrease in permeation rates and the formation of oxide layer. The hydrogen permeability of the tungsten films at 400 degrees C was calculated based on measured data.

Summary: Significant progress in the biodegradation of anthropogenic pollutants can be achieved by harnessing artificial community selection based on eco-evolutionary principles. These selected communities can be used directly in bioremediation applications or further analyzed and modified through systems biology, synthetic biology, and genetic engineering, leading to the discovery of novel biodegradation pathways.

Summary: The study found that aerobic Gammaproteobacterial methanotrophs dominate in assimilating CH4 under anoxic conditions in Arctic lakes, and these methanotrophs have the capacity to generate intermediates such as methanol, formaldehyde, and formate from CH4 oxidation. This expands the knowledge of aerobic methanotroph metabolic processes and suggests potential coupling of CH4 oxidation to iron reduction in the Arctic lakes.

Summary: This study presents a submillennial-resolution record of lake water oxygen isotope composition from chironomid head capsules in Burial Lake, north-west Alaska. The record spans from the Last Glacial Maximum to the present, showing large shifts in lake delta O-18 values. These values are interpreted to reflect changes in lake hydrology, temperature, precipitation and atmospheric circulation patterns.

Summary: The study revealed the movement patterns of an Arctic woolly mammoth that lived 17,100 years ago, showing variations in mobility across a geographically extensive range during its approximately 28-year lifespan. Maintaining such level of mobility for megafaunal species like mammoth would have become increasingly challenging as the ice age ended and the environment changed at high latitudes.
