Cells That Grip
Published:
The Cellular Potts Model already had filopodia — Gaussian-shaped membrane protrusions that extend, retract, and sense the local environment. But they were floating. They could push into the substrate, detect chemical gradients, and influence the Hamiltonian, but they had no concept of gripping. A real filopodium that contacts a stiff substrate forms focal adhesion complexes — clusters of integrin receptors that physically anchor the cell to the extracellular matrix. And those adhesions are not passive anchors. They are mechanosensors.
Light at Every Wavelength
Published:
The original dual photography transport matrix treats light as a single channel — or at most three channels for RGB. You project white patterns, capture color images, and the transport matrix T maps projector pixels to camera pixels as if all wavelengths behave the same way through the scene. For many materials, this is a reasonable approximation. For many others, it is not even close.
