Investigation of formation mechanism of tufa deposits by chemical breakdown of legacy paper mill sludge

The Depositional Record, Volume 12, Issue 1, February 2026.
This study reveals that legacy paper mill sludge can generate tufa deposits through calcium leaching and atmospheric CO2 interaction, acting as a carbon sink. The findings highlight its potential for low‐cost carbon sequestration and sustainable waste management.

A critical role of heterotrophic bacteria in early diagenesis of carbonates through exopolymer degradation and calcium release

The Depositional Record, Volume 12, Issue 1, February 2026.
Exopolymeric substances (EPS) produced in the photic zone and surface sediments sequester calcium. Below the sediment surface, heterotrophic bacteria degrade EPS, releasing calcium resulting in carbonate precipitation. This process, which continues for millennia deep in the core, is an important sink for atmospheric carbon dioxide.

Palaeoglacier reconstruction and dynamics of Cordillera Vilcanota in the tropical high Peruvian Andes

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

Anastomosis and Low Flows Sustain Resilient Groundwater Dependent Riparian Floodplains in an Agricultural River Valley, New Mexico

Hydrological Processes, Volume 40, Issue 2, February 2026.
Groundwater‐dependent native riparian ecosystems of the Gila River floodplain (a) near the upstream end of the valley in winter 2014 and (b) near the downstream valley end in summer 2018. Topographically complex floodplains create favourable conditions across the full breadth of the valley bottom for a diversity of native groundwater‐dependent ...

Differentiating Damp‐Heat and Cold‐Damp Diarrhea in Rat Models via Gut Microbiota Dysbiosis and Short‐Chain Fatty Acid Profiling

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
ABSTRACT On the basis of gut microbiota and short‐chain fatty acids (SCFAs), this study aims to identify diagnostic biomarkers for damp‐heat diarrhea and cold‐damp diarrhea. Rat models of damp‐heat diarrhea and cold‐damp diarrhea were established. Changes in body weight, body temperature, food intake, water consumption, and the diarrhea index were ...
