Lisa Randall's work doesn't say anything about dark matter interacting with baryonic (normal) matter via the strong nuclear force or the electromagnetic force (the former is responsible for binding the nucleus of atoms together, the latter for electromagnetic radiation and chemical bonds), so the kind of dark matter that she postulates could have nothing to do with biophotons or the supposed "additional mass of life" that Philip Benjamin mentions. Rather her suggestion about a new "hypothetical type of dark matter" is about a type of dark matter particle that interacts more strongly with other dark matter particles of the same type, different from the standard idea of "cold dark matter" that has almost no non-gravitational self-interaction. See the abstract of her paper at https://arxiv.org/abs/1303.1521 which talks about how this hypothetical form of dark matter could self-interact in a way that causes it "cool efficiently and form a disk within galaxies":
"Based on observational constraints on large scale structure and halo structure, dark matter is generally taken to be cold and essentially collisionless. On the other hand, given the large number of particles and forces in the visible world, a more complex dark sector could be a reasonable or even likely possibility. This hypothesis leads to testable consequences, perhaps portending the discovery of a rich hidden world neighboring our own. We consider a scenario that readily satisfies current bounds that we call Partially Interacting Dark Matter (PIDM). This scenario contains self-interacting dark matter, but it is not the dominant component. Even if PIDM contains only a fraction of the net dark matter density, comparable to the baryonic fraction, the subdominant component's interactions can lead to interesting and potentially observable consequences. Our primary focus will be the special case of Double-Disk Dark Matter (DDDM), in which self-interactions allow the dark matter to lose enough energy to lead to dynamics similar to those in the baryonic sector. We explore a simple model in which DDDM can cool efficiently and form a disk within galaxies, and we evaluate some of the possible observational signatures." Randall later offered the speculation that if such a disc exists, its gravitational influence on our solar system passing through it periodically over huge spans of time might disrupt the orbits of small bodies like asteroids and comets enough to make mass extinctions more likely during such transits, which could fit with prior speculations that mass extinctions seem roughly periodic (I remember this was once used to argue for the existence that the Sun could have a companion star, 'Nemesis', with an extremely long eccentric orbit, though from what I remember the whole idea that mass extinctions are periodic was dismissed by many as finding a false pattern in noisy data). This is discussed in the review of her book "Dark Matter and the Dinosaurs" at https://www.nytimes.com/2015/11/29/books/review/dark-matter-and-the-dinosaurs-by-lisa-randall.html which says that the hypothetical self-interaction force between dark matter has been called "dark light" (though the name is just an analogy, it would be separate from the electromagnetic force), and it also says that she emphasizes that all this is extremely speculative.
