Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

The FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.

When biology meets materials science – Interdisciplinary applications of electron microscopy

Journal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.

Preparation artefacts mask the detectability of crosslinking‐induced structural changes in electron microscopy of collagen hydrogels

Journal of Microscopy, EarlyView.
Abstract Collagen hydrogels are widely used as biomimetic three‐dimensional matrices whose mechanical behaviour depends strongly on fibrillar micro‐ and nanoarchitecture and crosslinking state. Electron microscopy offers high spatial resolution for structural analysis, but sample preparation can substantially distort highly hydrated collagen networks ...

Trait‐based plant ecology: some history and some future

New Phytologist, EarlyView.
Schematic of plant species range boundaries, some mechanisms that might set them, and some traits that might explain them. Summary Since around the year 2000, trait‐based ecology has become self‐aware as a strand of research within ecology. How did this happen? What is trait‐based ecology now? And where might it go in future?

Cortical lacunae, not xylem embolism, drive interspecific differences in freeze–thaw hydraulic dysfunction of conifer fine roots

New Phytologist, EarlyView.
Yellow‐cedar has experienced widespread decline as climate change reduces the snowpack that insulates its roots, but the mechanism of injury is unknown. We tested two competing hypotheses in roots of four conifers: loss of xylem conductivity from freeze‐thaw embolism, or loss of radial conductivity from direct freezing injury that forms cortical ...

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.
