The precision of concentration sensing is improved when cells communicate. Here we derive the physical limits to concentration sensing for cells that communicate over short distances by directly exchanging small molecules (juxtacrine signaling), or over longer distances by secreting and sensing a diffusive messenger molecule (autocrine signaling). In the latter case, we find that the optimal cell spacing can be large, due to a trade-off between maintaining communication strength and reducing…

Precision of Flow Sensing by Self-Communicating Cells.

The precision of flow sensing for two ubiquitous detection methods: absorption vs reversible binding to surface receptors is derived and it is found that binding is more precise due to the fact that absorption distorts the signal that the cell aims to detect.

The gift of gab: probing the limits of dynamic concentration-sensing across a network of communicating cells

This letter constructs a robust and general framework of signal estimation over continuous time Markov chains in order to address and answer questions about the limits and benefits to communication across a network of neighbor interactions.

Gift of gab: Probing the limits of dynamic concentration-sensing across a network of communicating cells

A robust and general framework of signal estimation over continuous time Markov chains is constructed in order to address and answer questions about communication across a network of neighbor interactions and the role of Poissonian vs. super Poissian dynamics in such a setting.

Cells are amazing sensors. Rod cells in our visual system can detect single photons [1], olfactory cells [2] and immune cells [3] can detect single molecules, and amoebae can respond to a difference

Multicellular sensing at a feedback-induced critical point.

A simple biochemical model with nonlinear feedback and multicellular communication is investigated to determine if criticality provides a functional benefit in terms of the ability to gain information about a stochastic chemical signal and finds that when signal fluctuations are slow, the mutual information between the signal and the intracellular readout is maximized at criticality.

Theory for the optimal detection of time-varying signals in cellular sensing systems

Applying the theory to the Escherichia coli chemotaxis system indicates that its integration time is not only optimal for sensing shallow gradients but also necessary to enable navigation in these gradients.

Receptor crosstalk improves concentration sensing of multiple ligands

It is demonstrated that crosstalk can improve precision in concentration sensing and discrimination tasks and is presented a proofreading scheme to realize an approximate estimation of multiple ligand concentrations that reaches a precision close to the derived optimal bounds.

Cellular Sensing Governs the Stability of Chemotactic Fronts.

It is theoretically shown that the stability of chemotactic fronts to morphological perturbations is determined by limitations in the ability of individual cells to sense and thereby respond to the chemical gradient, and suggested that the cells' sensory machinery might have evolved to avoid these limitations and ensure stable front propagation.

Annual review of genetics

In your article on Ed Tatum for the Annual Review of Genetics, I was struck by your remark about T. H. Morgan's strong encouragement of Carl Lindegren's work with Neurospora and thought you might want to soft pedal the notion of "strong unless you are reasonably sure of the facts".

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.
