For ages the mainstream view of dark matter was that it almost certainly existed, but it had not been detected in any way except indirectly as the missing mass in galaxies, even though people had reasonable theories as to what it was (WIMPs).
Nice to see some experiments are beginning to claim solid evidence for detection now (even if others are publishing negative results). Strange to think of ourselves in a world that not only has vast swathes of neutrinos passing straight through (almost) undetectably, but now loads of massive particles as well.
