Building on the open-source platform PubPub, we’re sharing the first iteration of our publishing website. In addition to posting our first set of research pubs, we’re documenting our progress in developing this new system for sharing science and hope you’ll provide feedback.
Cells can be highly motile, moving in and out of a microscope’s field of view. Understanding complex life cycles is difficult without continuous observation. To overcome this challenge, we’ve developed a 3D-printed microchamber device to confine cells for long-term visualization.
Quantifying movement is a powerful window into cellular functions. However, cells can generate movement through a variety of complex mechanisms. Here, we generate a flexible framework for comparing an especially variable type of motility: cellular crawling.
The process of deciding whether a candidate actin homolog represents a “true” actin is tricky. We propose clear and data-driven criteria to define actin that highlight the functional importance of this protein while accounting for phylogenetic diversity.
Long protrusions from several microalgal species appear to help cells move, capture prey, transport mitochondria and chloroplasts, and more. Are they filopodia that evolved abilities more like other actin- or microtubule-based structures, or are they something new?
