Theory of Cell Body Lensing and Phototaxis Sign Reversal in "Eyeless" Mutants of
Sumit Kumar Birwa, Ming Yang, Adriana I. Pesci +1
Phototaxis of many species of green algae relies upon directional sensitivity of their membrane-bound photoreceptors, which arises from the presence of a pigmented "eyespot" behind…
Phototactic Decision-Making by Micro-Algae
Shantanu Raikwar, Adham Al-Kassem, Nir S. Gov +3
We study how simple eukaryotic organisms make decisions in response to competing stimuli in the context of phototaxis by the unicellular alga . While neg…
Algal Optics
Ming Yang, Sumit Kumar Birwa, Raymond E. Goldstein
Nearly a decade ago it was discovered that the spherical cell body of the alga can act as a lens to concentrate incoming light onto the cell's membrane-…
Spatiotemporal distribution of the glycoprotein pherophorin II reveals stochastic geometry of the growing ECM of
Benjamin von der Heyde, Anand Srinivasan, Sumit Kumar Birwa +4
The evolution of multicellularity involved the transformation of a simple cell wall of unicellular ancestors into a complex, multifunctional extracellular matrix (ECM). A suitable…
The 2024 Motile Active Matter Roadmap
Gerhard Gompper, Howard A. Stone, Christina Kurzthaler +29
Activity and autonomous motion are fundamental aspects of many living and engineering systems. Here, the scale of biological agents covers a wide range, from nanomotors, cytoskelet…
