Agitated ants: regulation and self-organization of incipient nest excavation via collisional cues Open
Ants are millimetres in scale yet collectively create metre-scale nests in diverse substrates. To discover principles by which ant collectives self-organize to excavate crowded, narrow tunnels, we studied incipient excavation in small grou…

Gliders in shape-changing active matter Open
We report in experiment and simulation the spontaneous formation of dynamically bound pairs of shape changing smarticle robots undergoing locally repulsive collisions. Borrowing terminology from Conway's simulated Game of Life, these physi…

Toward Task Capable Active Matter: Learning to Avoid Clogging in Confined Collectives via Collisions Open
Social organisms which construct nests consisting of tunnels and chambers necessarily navigate confined and crowded conditions. Unlike low density collectives like bird flocks and insect swarms in which hydrodynamic and statistical phenome…

Angular super-resolution retrieval in small-angle X-ray scattering Open
Small-angle X-ray scattering (SAXS) techniques enable convenient nanoscopic characterization for various systems and conditions. Unlike synchrotron-based setups, lab-based SAXS systems intrinsically suffer from lower X-ray flux and limited…

Programming Active Granular Matter with Mechanically Induced Phase Changes. Open
Emergent behavior of particles on a lattice has been analyzed extensively in mathematics with possible analogies to physical phenomena such as clustering in colloidal systems. While there exists a rich pool of interesting results, most are…

Glassy Dynamics and Memory Effects in an Intrinsically Disordered Protein Construct Open
Glassy, nonexponential relaxations in globular proteins are typically attributed to conformational behaviors that are missing from intrinsically disordered proteins. Yet, we show that single molecules of a disordered-protein construct disp…

Universal and Accessible Entropy Estimation Using a Compression Algorithm Open
Entropy and free-energy estimation are key in thermodynamic characterization of simulated systems ranging from spin models through polymers, colloids, protein structure, and drug design. Current techniques suffer from being model specific,…

Nanoparticle Mobility over a Surface as a Probe for Weak Transient Disordered Peptide–Peptide Interactions Open
Weak interactions form the core basis of a vast number of biological processes, in particular, those involving intrinsically disordered proteins. Here, we establish a new technique capable of probing these weak interactions between synthet…

Order and disorder in intermediate filament proteins Open
Intermediate filaments (IFs), important components of the cytoskeleton, provide a versatile, tunable network of self‐assembled proteins. IF proteins contain three distinct domains: an α‐helical structured rod domain, flanked by intrinsical…
