Note the "so far". It will be interesting to see if the solution
to the dark matter puzzle will require us to reasses the authors
conclusion.

The history of science if full of ideas which went nowhere. If you are
worried about "so far", search the literature. If nothing has come of
this, there is probably a reason.

If you think this is relevant to anything else, say so and why.

Salt particles in zero gravity tend to spontaneusly make clumps that are
somehow electrostatically defined.

Static electricity could have an important role in planet formation and
maybe star formation.

van der waals forces not static electricity

to get attraction you need opposite charges, not likely in this situatiom

Interesting.

1) The cited article says:

Although these experiments lacked formal controls to identify the
precise clumping mechanism, it is apparently electrostatic.

2) Van der waals forces are inherently electrostatic. Dipoles can pair
with their dipoles attracting other similar molecules, so I do
notunderstand the difference being made here. Van der waals forces ARE
electrostatic...

If you have dipolar molecules yes, you have opposite charges. If you
have charge accumulation by mechanical input it is the same.
