Dark matter, cancer, dinosaurs and galaxies

Dark Matter’s Deep Reach - NYTimes.com

I had missed Bee Hossenfelder's suggestion, referred to in the open of this decent article on dark matter, that weakly interacting dark matter passing through humans might be capable of causing cancer.   (But the effect would be way less than the risk from cosmic rays.)  Another suggestion is that it may contribute to volcanism.

Both rather interesting suggestions.   As is the one I read elsewhere today, that perhaps there is evidence for dark matter interacting with itself via a force only it feels.
