Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Spruce Needles‐Derived N‐Doped Carbon as an Excellent Anode Material for Li‐Ion Batteries

open access: yesChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Spruce needles‐derived N‐doped carbon is superior to commercial graphite as an anode material in Li‐ion batteries. Graphite‐based anodes have long underpinned the commercial success of lithium‐ion batteries (LIBs), enabling stable and reliable electrochemical performance.

Dynamic Risk Assessment of Karst Tunnel Collapse Based on Fuzzy-AHP: A Case Study of the LianHuaShan Tunnel, China

open access: yesAdvances in Civil Engineering, 2022
Tunnel collapse in the karst tunnel occurs suddenly. Dynamic risk assessment for tunnel collapse is more accurate than static analysis, which is not enough at the stage. The study designs a new questionnaire to establish dynamic risk assessment for karst

Geomorphological mapping of the Becca d'Aver deep‐seated gravitational slope deformation (Aosta Valley, Italy) based on multi‐scale and multi‐sensor analysis

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Geomorphological characterization of the DsGSD enables us to identify the sources of sediment that could be mobilized as debris flows. In the area, pseudo‐badlands morphotype has been defined and mapped, representing the main sources of risk beside abandoned quarry deposits.
