Because it's the discontinuities in the commutator where the sparks fly (with much help from self-induction of the motor's coils) and erode the ring and brushes.
The funny thing about this is that it's almost realistic
But in fact of course geography plays a big part
That "non-existent" country between France and Spain would actually be the center of Occitan/Langues d'Oc. (Well, it's actually the location of Andorra)
It is also in the middle of the Pyrenees so of course that is going to push population out to the sides
Same thing for where the areas "bleed over" water regions or some rivers
Me too, which is why I mostly use Windows as main OS laptop OS since Windows 7[0], however with current geopolitics, eventually we might have to really chose something else, even if the ergonomics aren't there.

I would be more worried if the blotted area was different (the dark blob) - or if data in a datasheet (something like test specificity, level of detection, etc) was wrong
Now, if while preparing the images they needed to do some editorial choices (or it is well possible a person in the editorial group was told to 'enhance the images' but wasn't aware of the details) because of limitations in doing the experiment then this is probably not a big deal

Or if more than one blob is present (i.e. blobs at different molecular weights) for a supposedly selective and specific antibody that should show exactly one blob on the blot.

Editorial choices on raw scientific data are a big no-no.

I don't think you can find a picture in an article that hasn't been photoshopped in one way or another (which is mostly ok as long as it is not misleading)

These images are provided on the datasheet and form the basis for the level of detection / specificity claims
