Fire ants, Solenopsis invicta, link their bodies together to form structures such as rafts, bivouacs and bridges. Such structures are in danger of being damaged by natural disturbances such as passing water currents. In this combined experimental and theoretical study, we investigate the self-healing of ant assemblages. We press two ant aggregations together and measure the forces to pull them apart. As the group size increases, the contribution of each ant decreases. This phenomenon, known as…

Collective treadmilling in fire ant rafts permits sustained protrusion growth

Ant raft dynamics mirror the treadmilling that facilitates morphogenesis and motility of cytoskeletons, thus providing another example in which reshaping of condensed active matter is explained by free constituent transport, yet whose continuance relies on perpetual phase transition between structural and free members.

Treadmilling and dynamic protrusions in fire ant rafts

It is shown here that sustained shape evolution is permitted by the competing mechanisms of perpetual raft contraction aided by the transition of bulk structural ants to the free active layer and outward raft expansion owing to the deposition of free ants into the structural network at the edges, culminating in global treadmilling.

Fire ants perpetually rebuild sinking towers

This combined experimental and theoretical study investigates the shape and rate of construction of ant towers around a central support, and combines the behavioural rules that produce rafts on water with measurements of adhesion and attachment strength to model the rate of growth of the tower.

Interactions between worker ants may influence the growth of ant cemeteries

The results suggest that the corpse-carrying behaviour of worker ants might be influenced by interactions with their nest-mates because there is evidence that ant behaviour can be affected by encounter rates.

Social Insects and Beyond: The Physics of Soft, Dense Invertebrate Aggregations

This review of dense aggregations of a variety of insects, other arthropods, and worms from a soft matter standpoint shows that these may just be the tip of an iceberg of superorganisms that take advantage of physical interactions and simple behavioral rules to adapt to changing environments.

Scaling of speed with group size in cooperative transport by the ant Novomessor cockerelli

This work tested the hypothesis that groups are slower when porters must encircle the load to carry it, and used simulations to explore a scenario in which ants vary in their intrinsic speed and the group's speed is limited by that of its slowest member.

Organismal aggregations exhibit fluidic behaviors: a review

It is shown how the properties of density, viscosity, and surface tension have strong parallels in the structure and behavior of aggregations of contrasting scale and domain, which may inspire new tools for the analysis of collective motion.

Computational exploration of treadmilling and protrusion growth observed in fire ant rafts

This work demonstrates through an ant-inspired, agent-based numerical model how protrusions in ant rafts may emerge spontaneously due to local interactions and how phases of exploratory protrusion growth may be induced by increased ant activity.

Ant Droplet Dynamics Evolve via Individual Decision-Making

An agent-based model where artificial ants aggregated, thereby resulting in chain and droplet growth and it was revealed that the droplet dynamics of the proposed model partly matched the time series of droplets of real ants.

Entangled active matter: From cells to ants

This review presents the biology, mechanics and dynamics of both entangled cells and ants, and applies concepts from soft matter physics and wetting to characterize these systems as well as to point out their differences, which arise from their differences in size.

Fire ants actively control spacing and orientation within self-assemblages

An important role of ant polymorphism is found in promoting self-aggregation: a large distribution of ant sizes permits small ants to fit between the legs of larger ants, a phenomenon that increases the number of average connections per ant.

Fire ants self-assemble into waterproof rafts to survive floods

It is found that ants can considerably enhance their water repellency by linking their bodies together, a process analogous to the weaving of a waterproof fabric, in a self-assembled hydrophobic surface.

Self assembly of a model multicellular organism resembling the Dictyostelium slime molds

It is found that if a single cell is able to emit a signal which induces others to move towards it, then a colony of single-cell organisms can assemble into shapes as complex as a tower, a ball atop a stalk, or a fast-moving slug.

Advancement on techniques for the separation and maintenance of the red imported fire ant colonies

All the new techniques for separating and maintaining colonies of red imported fire ants, Solenopsis invicta Buren, are collated in one reference which readers can use as a manual.

Extensional rheology of entangled granular materials

We study the response of collections of U-shaped granular particles to extensional loading. Cylindrical samples elongate in bursts, as existing particle entanglements yield and new ones are created.

Two-dimensional packing in prolate granular materials.

This work investigates the two-dimensional packing of extremely prolate (aspect ratio alpha=L/D>10) granular materials, comparing experiments with Monte Carlo simulations and quantifies the orientational correlation of particles and finds a correlation length of two particle lengths.

Column collapse of granular rods.

The collapse of granular rodpiles is investigated as a function of particle (length/diameter) and pile (height/radius) aspect ratio and it is found that, for all particle aspect ratios below 24, there exists a critical height Hl below which the pile never collapses, and a second height Hu abovewhich the pile always collapses.

Entangled granular media.

The geometrically induced cohesion of ensembles of granular "u particles" that mechanically entangle through particle interpenetration is studied to reveal that optimal strength results from competition between packing and entanglement.

Modelling suggests that biochemical regulation of mitosis is fundamental to the process, and that a single chemical with a simple regulatory effect can account for the healing of circular epidermal wounds.

Cutaneous wound healing.

The primary goals of the treatment of wounds are rapid wound closure and a functional and aesthetically satisfactory scar.
