Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Abstract Rubbing phosphoric acid during etching has been shown to improve surface roughness in prepared enamel. This study aimed to compare intact enamel's surface roughness and resin tag lengths after etching with and without rubbing. Extracted sound third molars were used for testing, mesially for conventional and distally for dynamic (rubbing ...

Macromolecule‐dependent increases in extracellular fluid viscosity alter cell phenotype. These distinct macromolecules create different extracellular environments that modulate cell morphology and mechanoprotein expression, migration and invasion capacity, and cellular mechanical properties.

Axial muscle‐fibre orientations in larval zebrafish
In 4 days post‐fertilization zebrafish larvae, the fast axial muscle fibres follow helical trajectories that taper towards the tail. Adjacent muscle fibres form substantial angles relative to each other to accommodate this pattern. Using a novel semi‐automatic method, we quantified 3D fibre angles over the whole muscle volume.

Simple rhamphotheca are externally homogeneous but internally are composed of several corneous layers with varying hardness. Areas under more mechanical stress such as the rostral portion and the tomia are significantly harder than other areas. Abstract Corneous sheaths on the jaws of beaked tetrapods, or rhamphothecae, are classified as simple or ...
