Multicellular chemotaxis can occur via individually chemotaxing cells that are mechanically coupled. Alternatively, it can emerge collectively, from cells chemotaxing differently in a group than they would individually. Here we consider collective movement that emerges from cells on the exterior of the collective responding to chemotactic signals, whereas bulk cells remain uninvolved in sensing and directing the collective. We find that the precision of this type of emergent chemotaxis is…

Evolution of multicellularity by collective integration of spatial information
TLDR
It is shown that multicellular aggregates evolve because they perform chemo-taxis more efficiently than single cells, and collective behaviour can be an emergent selective driver for undifferentiatedMulticellularity.
Physical constraints on accuracy and persistence during breast cancer cell chemotaxis
TLDR
It is observed in both experiments and simulations that the chemotactic accuracy, but not the persistence or speed, increases with the gradient strength, and it is proposed that cells’ chemOTactic accuracy and persistence are mutually constrained.
Capacity to multitask limits cellular chemotaxis
TLDR
A novel biophysical framework is proposed that puts forward the hypothesis that the antagonism of chemoattractants is not because of crosstalk, but because of the saturation of the intracellular signal processing capacity.

TLDR
Experimental evidence showing that cells collectively sense gradients of many signal types, and the models and physical principles involved are discussed, and new routes by which experiments and theory can expand the understanding of these problems are proposed.
Cell cluster migration: Connecting experiments with physical models.
Cell-to-cell variation sets a tissue-rheology–dependent bound on collective gradient sensing
TLDR
It is found that when different cells cooperate, the resulting bias can be much larger than the effects of ligand–receptor binding, which means fluid clusters are better able to sense gradients and derive a link between cluster accuracy, cell-to-cell variation, and the cluster rheology.
Autologous chemotaxis at high cell density
TLDR
The cell density at which sensing fails is determined and it is found that it agrees with experimental observations of metastatic cancer cells, shedding light on a sensory strategy employed by cancer cells in dense tumor environments.
Picking winners in cell-cell collisions: wetting, speed, and contact
TLDR
A model for two-cell collisions within the phase field approach, which treats cells as deformable objects, and can reproduce the observation that cells with high speed and small contact angles are more likely to win with two different assumptions for how cells interact.
Diffusion vs. direct transport in the precision of morphogen readout
TLDR
It is found that direct transport establishes a morphogen profile without adding noise in the process, and it is predicted that for suffciently large values of profile length, the diffusion mechanism is many times more precise due to a higher refresh rate of morphogen molecules.
Geometry, packing, and evolutionary paths to increased multicellular size.
TLDR
It is found that changing geometry is a far more efficient route to large size than evolving increased intercellular adhesion, and increasing cellular aspect ratio is on average ∼13 times more effective than increasing bond strength at increasing the number of cells in a cluster.

Cell–cell communication enhances the capacity of cell ensembles to sense shallow gradients during morphogenesis
TLDR
It is found that multicellular sensing enables detection of and response to shallow epidermal growth factor (EGF) gradients that are undetectable by single cells, and this provides a framework for understanding the advantages and limitations of sensory information processing by relays of chemically coupled cells.
Cooperative Roles of SDF-1α and EGF Gradients on Tumor Cell Migration Revealed by a Robust 3D Microfluidic Model
TLDR
The findings demonstrate the capabilities of the microfluidic model in re-creating complex microenvironments for cells, and the importance of cooperative roles of multiple cytokine and growth factor gradients in regulating cell migration in 3D environments.
Neural crest cell dynamics revealed by time-lapse video microscopy of whole embryo chick explant cultures.
TLDR
The unpredictable cell trajectories, the mixing of neural crest cells between adjoining rhombomeres, and the diversity in cell migration behavior within any particular region imply that no single mechanism guides migration.
Trends in Ecology & Evolution
TLDR
Hair and feathers likely evolved in the Early Triassic ancestors of mammals and birds, at a time when synapsids and archosaurs show independent evidence of higher metabolic rates (erect gait and endothermy), as part of a major resetting of terrestrial ecosystems following the devastating end-Permian mass extinction.

TLDR
It is shown that the full set of hydromagnetic equations admit five more integrals, besides the energy integral, if dissipative processes are absent, which made it possible to formulate a variational principle for the force-free magnetic fields.
