Marvellous glimpses into the miniscule worlds inside our own cells. Incredible to think that the processes visualised in these videos are part of what keeps us alive, breathing, moving, thinking, and more.
(P.S.: the videos are beautiful but it helps also to read the article text to get a sense of what’s happening, since there is no voiceover/captioning in the videos.)
We dive into the cell to see what happens next. Molecules swim through the cell like dolphins, relaying the signal from the outside. Certain genes switch on, and the cell makes new proteins that are put into a blob called a vesicle. An oxlike protein called kinesin hauls the vesicle across the cell, walking along a molecular cable.
