A few years ago, I wrote a blog post about a paper published on the subject of dark matter as a potential cancer-causing agent. Today, a related paper was published on the potential of "macros" -- dark matter object of macroscopic size (or weight) that could cause death or serious injury in humans, in the form a bullet-like wounds. The apparent absence of such dark matter deaths is then used to put limits on the actual occurrence of such forms of dark matter.
The paper is published open access in Physics Letters B, here.
