Gene‐Informed Modeling of Denitrification Process in Groundwater Through Dynamic Flux Balance Analysis and Deep Learning

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract We introduce two gene‐informed approaches that, for the first time, explicitly incorporate microbial genomic information into groundwater denitrification simulations. First, we couple the dynamic flux balance analysis (DFBA, which resolves genome‐resolved metabolic networks) with the PFLOTRAN reactive transport model (RTM).

Electrode structures of solid–liquid interface‐based triboelectric nanogenerators and their applications

Droplet, Volume 5, Issue 2, April 2026.
In this review, we have summarized the working principles and equivalent circuit diagrams of solid‐liquid interface triboelectric nanogenerators with different electrode structures, as well as the applications of devices with such structures in droplet mechanical energy harvesting and self‐powered sensing of liquid samples, along with their respective ...

Magnetic and Isotopic Analyses Unravel the Abundance and Sources of Magnetic Nanoparticles in Urban PM2.5

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Magnetic nanoparticles (NPs) are increasingly recognized as an emerging threat to ecosystems and human health, yet their mass concentrations and sources in urban atmosphere remain poorly characterized. Here, we developed a robust methodology for the extraction, quantification, and source apportionment of magnetic NPs in urban PM2.5.

Growth of candidate phyla radiation bacteria in groundwater incubations reveals widespread adaptations to oxic conditions

Microbiome
Background The candidate phyla radiation (CPR) comprises a widespread but poorly understood group of bacteria with limited cultured representatives, largely due to their metabolic dependencies on microbial hosts.

Enhanced Reconstruction of Holocene Bryophytes From Sedimentary Ancient DNA Using Bryophyte‐Targeted Primers

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Bryophyte‐targeted primers captured a longer DNA fragment, moving beyond the indirect “bycatch” approach using vascular plant primers. This improved detection and recovered greater bryophyte diversity, with substantial overlap with taxa obtained through bycatch.

Metagenomic Analysis of Thawing Permafrost Highlights Links Between Carbon and Nitrogen Cycling Processes in Abrupt Thaw Simulation

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Abrupt permafrost thaw events are projected to contribute up to 40% of permafrost carbon (C) release to the atmosphere. They involve sudden hydrological shifts within the soil column; however, the exact microbial functional pathway shifts induced by these events remain cryptic. To investigate how C and nutrient cycling processes differ in thaw

High latitude terrestrial carbon isotope and mercury perturbations across the Late Triassic Carnian Pluvial Episode in Northwestern China

Scientific Reports
The Carnian Pluvial Episode (CPE) was a Late Triassic interval of global environmental changes and biological turnovers linked to C-cycle perturbation and global warming.

Freezing Tolerance of Thermophilic Bacterial Endospores in Marine Sediments

Frontiers in Microbiology, 2019
Dormant endospores of anaerobic, thermophilic bacteria found in cold marine sediments offer a useful model for studying microbial biogeography, dispersal, and survival.

Two worlds beneath: Distinct microbial strategies of the rock-attached and planktonic subsurface biosphere

Microbiome
Background Microorganisms in groundwater ecosystems exist either as planktonic cells or as attached communities on aquifer rock surfaces. Attached cells outnumber planktonic ones by at least three orders of magnitude, suggesting a critical role in ...

Microbial Community Structure and Arsenic Biogeochemistry in Two Arsenic-Impacted Aquifers in Bangladesh

mBio, 2017
Long-term exposure to trace levels of arsenic (As) in shallow groundwater used for drinking and irrigation puts millions of people at risk of chronic disease.
