Evidence for Massive Neutrinos, which also Interact with the Earth

Just want to highlight the following research paper by physicists in the UK.

Massive neutrinos solve a cosmological conundrum

They estimate that the sum of the masses of neutrinos is 0.32 eV +/- 0.081 eV.
You have access to APS journals, you can find their paper here.

It's unclear to me what is the connection between this group's findings and the 2-10 keV  particle that seems to explain dark matter. So, I welcome feedback in the comments section.

I'd also like to highlight some recent research from Japan, showing that solar neutrinos interact with the Earth. In other words, as the solar neutrinos pass through the Earth, they can be convert from one type of neutrino into another type of neutrino faster than if the neutrinos were travelling through a vacuum.
Pretty cool that, once again, predictions using the Standard Model were confirmed experimentally!
