Transient cell-cell contact of eukaryotic cells, called contact following locomotion, causes cell density segregation, and its high-density region traveled as a band within the disordered background.
Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.
For the same bacterial strain, the swarming phenotype can be biophysically discerned from swimming phenotype based on the motion pattern under circular confinement on a soft agar.
The concentration of motile bacteria, expressing a light-driven proton pump, can be precisely controlled in space and time by spatially modulating their swimming speeds with a structured light pattern.
Microtubule streaming driven by molecular motors covers characteristic times that span several orders of magnitude from fast, single-microtubule sliding on molecular scales to slow, collective motion on cellular scales.
Staff from the Mayo Clinic in the US and the Karolinska Institute in Sweden describe a joint transatlantic course intended to broaden the horizons of the next generation of researchers in the field of regenerative medicine.
Zebrafish use their sense of gravity and their cerebellum to coordinate the fin and body movements that, as they develop, allow them to better maintain balance as they climb.
The first three-dimensional structure of the PI3KC3 complex I, which is involved in autophagy, provides a framework for understanding the allosteric regulation of lipid kinase activity.
