Years ago, I started the GalaxyGoo Cell Project, and we ran huge workshops at the Maker Faire. Where we led kids of all ages and they built 3D models of cells as we talked them through the protein pathway.
They took their models home, and let them dry, before slicing them open an looked at their cross sections.
We took them on a macro-simulation of electron microscopy.
It was amazing.

🤒 Why do we actually get a #fever? One reason is that immune cells move faster at higher temperatures. A team led by Stefan Wieser at the Institute of Zoology has now uncovered the molecular mechanism behind this process, with the motor protein myosin II taking center stage.

Heat acts as a Turbo-Boost for Immune Cells
Temperature is a key physiological factor that determines the speed of immune reactions. While this may seem obvious, it has remained largely unexplored at the single-cell level—until now. Stefan Wieser from the Institute of Zoology at the University of Innsbruck and his colleagues report in Developmental Cell that the motor protein Myosin II regulates the temperature sensitivity of immune cells and drives the acceleration of immune responses at elevated body temperature.
