text: 'The emergence of large-scale order in self-organized systems relies on local
interactions between individual components. During bacterial cell division, FtsZ
-- a prokaryotic homologue of the eukaryotic protein tubulin -- polymerizes into
treadmilling filaments that further organize into a cytoskeletal ring. In vitro,
FtsZ filaments can form dynamic chiral assemblies. However, how the active and
passive properties of individual filaments relate to these large-scale self-organized
structures remains poorly understood. Here, we connect single filament properties
with the mesoscopic scale by combining minimal active matter simulations and biochemical
reconstitution experiments. We show that density and flexibility of active chiral
filaments define their global order. At intermediate densities, curved, flexible
filaments organize into chiral rings and polar bands. An effectively nematic organization
dominates for high densities and for straight, mutant filaments with increased
rigidity. Our predicted phase diagram captures these features quantitatively,
demonstrating how the flexibility, density and chirality of active filaments affect
their collective behaviour. Our findings shed light on the fundamental properties
of active chiral matter and explain how treadmilling FtsZ filaments organize during
bacterial cell division. '

text: The emergence of large-scale order in self-organized systems relies on local
interactions between individual components. During bacterial cell division, FtsZ—a
prokaryotic homologue of the eukaryotic protein tubulin—polymerizes into treadmilling
filaments that further organize into a cytoskeletal ring. In vitro, FtsZ filaments
can form dynamic chiral assemblies. However, how the active and passive properties
of individual filaments relate to these large-scale self-organized structures
remains poorly understood. Here we connect single-filament properties with the
mesoscopic scale by combining minimal active matter simulations and biochemical
reconstitution experiments. We show that the density and flexibility of active
chiral filaments define their global order. At intermediate densities, curved,
flexible filaments organize into chiral rings and polar bands. An effectively
nematic organization dominates for high densities and for straight, mutant filaments
with increased rigidity. Our predicted phase diagram quantitatively captures these
features, demonstrating how the flexibility, density and chirality of the active
filaments affect their collective behaviour. Our findings shed light on the fundamental
properties of active chiral matter and explain how treadmilling FtsZ filaments
organize during bacterial cell division.

text: Wood, as the most abundant carbon dioxide storing bioresource, is currently
driven beyond its traditional use through creative innovations and nanotechnology.
For many properties the micro- and nanostructure plays a crucial role and one
key challenge is control and detection of chemical and physical processes in the
confined microstructure and nanopores of the wooden cell wall. In this study,
correlative Raman and atomic force microscopy show high potential for tracking
in situ molecular rearrangement of wood polymers during compression. More water
molecules (interpreted as wider cellulose microfibril distances) and disentangling
of hemicellulose chains are detected in the opened cell wall regions, whereas
an increase of lignin is revealed in the compressed areas. These results support
a new more “loose” cell wall model based on flexible lignin nanodomains and advance
our knowledge of the molecular reorganization during deformation of wood for optimized
processing and utilization.
