Evaluating the Energy Efficiency of Optimization Techniques in C, Python, and Java

Software: Practice and Experience, Volume 56, Issue 10, Page 1221-1250, October 2026.
ABSTRACT Background Software plays a critical role in modern society, but its energy consumption is a growing concern. This issue is especially evident in the Internet of Things (IoT), which involves billions of devices operating under strict energy constraints, most of which rely on C Programming Language (PL) because of its energy efficiency.

The South Atlantic Meridional Overturning Circulation at 34.5°S in 2017 and 2022

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract The Atlantic Meridional Overturning Circulation (AMOC) at 34.5°S is investigated using hydrographic data from two research cruises conducted in 2017 and 2022. Data from the South AMOC Basin‐wide Array (SAMBA) are used to close the 2022 section.

Subsurface Hydrocarbon Biodegradation in the Context of Microbial Habitability and Hydrogeologic, Thermal, and Geologic Evolution of the Colorado Plateau

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Subsurface microbial ecosystems associated with hydrocarbon reservoirs are shaped by temperature, salinity, redox gradients, and fluid flow. However, the drivers of microbial activity and hydrocarbon biodegradation over geologic timescales remain poorly constrained.

Overlooked components of lipid metabolism: Odd‐chain polyunsaturated fatty acids in photosynthetic microorganisms

Journal of Phycology, Volume 62, Issue 5, Page 1428-1439, October 2026.
Abstract This mini‐review examines odd‐carbon polyunsaturated fatty acids (odd‐PUFAs), a rare but biologically significant group of fatty acids in photosynthetic microorganisms. Odd‐PUFAs are straight‐chain fatty acids containing an odd number of carbon atoms and two or more methylene‐interrupted double bonds. They typically account for less than 1% of
