Self-assembly of bacterial ice nucleation proteins is required for efficient activity and is mediated by electrostatic interactions, creating long and thin fibres.

Rudimentary cross-catalytic replication can be established by double-hairpins of tRNA-like sequences, implying that replication and translation could have emerged along a common evolutionary trajectory.
Nucleation, elasticity theory, and simulations were combined to construct a general phase diagram that elucidates the conditions for successful viral assembly and the key factors to prevent it.
A trait-based model of dryland vegetation uncovers the roles of spatial self-organization in maintaining biodiversity in a changing climate and offers novel ways of managing ecosystems at risk.
TANGO1 functions as a linactant filament to stabilize shallow COPII-coated buds, and after which membrane tension regulation, possibly mediated by TANGO1-controlled membrane fusion, facilitates bud elongation for procollagen export.
Nanoscaleimaging reveals that animal septins form dense filamentous networks on biomimeticlipid membranes, explaining how septins may regulate cell surface rigidity.
Biochemical data demonstrate that the conformation of the target site DNA can dramatically modulate the kinetics and directionality of the otherwise isoenergetic transposition reaction of DDE transposases.
