Developing and exploring a theory for the lateral erosion of bedrock channels for use in landscape evolution models [PDF]
Earth Surface Dynamics, 2018 Understanding how a bedrock river erodes its banks laterally is a frontier in geomorphology. Theories for the vertical incision of bedrock channels are widely implemented in the current generation of landscape evolution models.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

FEBS Letters, EarlyView.Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Smaller is better: nanobodies meet NMR
FEBS Letters, EarlyView.Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Geomorphology and channel network patterns of the Mekong River in Cambodia
, 2012 Published, well-described examples of multiple mixed bedrock-alluvial character systems largely pertain to small to medium systems. No descriptions exist for large river systems such as the Mekong River in Cambodia (South East Asia).

Bedrock-sculpturing by Tsunami, South Coast New South Wales, Australia
, 1996 Bedrock-sculpturing resulting in s-forms is associated with catastrophic flooding in near- and subglacial environments produced by flow velocities approximating 10 m s-1.

Gamma Rays Signal the Vulnerability of Forest to Extreme Drought
Geophysical Research LettersExtreme drought and heat are driving forest die‐off globally, yet regional‐scale mapping of subsurface water storage capacity, governing forest vulnerability, remains a major challenge.
