Wetting deformation prediction of compacted lateritic clay subjected to dynamic loading

Journal of Rock Mechanics and Geotechnical Engineering
Rainfall infiltration and groundwater level fluctuation cause the subgrade filler to be wetted, rendering the subgrade prone to accelerated permanent deformation under long-term traffic loading.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Mechanism and prevention of rock burst induced by horizontal sublevel mining of a steeply inclined extra-thick coal seam

Meikuang Anquan, 2021
In order to prevent the rock burst caused by horizontal sublevel mining of a steeply inclined extra-thick coal seam, the mechanism of rock burst induced by the superposition of dynamic and static loads and the corresponding prevention measures were ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Micromechanics-based evaluation of strain rate effect on direct tensile failure in brittle rocks during dynamic geohazards

Geohazard Mechanics
Brittle rocks exhibit significantly lower dynamic direct tensile strength compared to their compressive strength, and the tensile strength is relatively difficult to be quantitatively measured through experiments.

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
