    Cell Adhesion Pattern Shows Conserved #Scalings under #Geometrical Control

    Studying the relationship between the size and the #anatomy and #physiology of #living #organisms has proven useful in deciphering what the key physical constraints are that apply to them. For instance, total adhesive pad area is found to #scale like organism mass over a wide variety of animal species, possibly to resist against body weight.

    In this study, we apply this approach at the cell scale to ask how large-scale geometrical constraints affect the organisation of #adhesion patches and the size of #cellSubstrate contact at different stages of the #cellSpreading process. Indeed, #cells, like many animals, adhere to their substrate. For that, they use specific protein complexes, called #focalAdhesions, which form patches often situated at the cell periphery.

  3. Maybe sudden differences of temperature, perhaps by only a few degrees, caused rapid nucleation for the ice to form in linear, angular, #geometrical shapes.

    There is #symmetry to the hollow columns, needles, ridges, triangular, rectangular and cube features in this wetland, autumnal pool.

    The ice didn't transition to smooth, sheet ice with air pocket features when I zoom-in to the photo of the entire autumnal pool either.
