There is a movement among major journals to provide some open access, but they make their money by not doing so for everything.
arxiv from what I see of it seems to be a wide ASAP site for work in progress, unreviewed. There is some interesting stuff there, but I try not to take it seriously if involved in something important, unless I know of the authorship.
As for the disappearing title:
I suspect it's about the blocked respondent, coupled with a bug. It's not a big deal actually. I'm acutely aware of the basic ideas underlying the topic and certainly don't need access to it, and if I wish to do so, I can through "My Posts."
The worst part was logging out to check out the problem and being forced to recognize the respondent in question displaying, as always, the inability to have a coherent thought. I think it knows how to work the smiley buttons, and not much else. It's always the same with that loon.
As for the excerpts, I didn't even excerpt the best part of the paper, because the entire post was thrown together quickly when I was running out of time and had other things to do connected with my real life. However a Nature journal pointing out that antinukism kills people seemed worth noting, even if sloppily. The full paper indicates a putative US nuclear phase out as causing 5000 + deaths/year from air pollution. Each year that the US were to operate without nuclear energy is said to be expected to result in 80,000 to 170,000 deaths in the century from CO2 related effects, climate change. In other words, ten years without nuclear would lead to 800,000 to 1,700,000 deaths over the course of the century.
My time on the planet is nearly over, but I want to go out trying, within my limited ability, to get this truth as much exposure as possible.
