From the article: &quot;The new AMS results may ultimately help scientists narrow in on the origin and features of dark matter&quot;<p>So yet another link-bait headline.

This is a surprisingly Vague article for MIT press. I understand its just the press release and not the white paper but could there not be a little more detail? Perhaps Interns are writing it could it not have a bit more content be it data, opinion from scientist, the leading theory in the area.<p>Its exciting stuff and not a dead end article, so little progress has been made in this field and the unknowns are so fast that eve a glimpse is interesting.

Hmm... whenever I see this [articles about dark matter or dark energy] nowadays I think back to something Dr. Neil deGrasse Tyson said on the subject along the lines of &quot;We&#x27;re calling it Dark Matter or Dark Energy because can we measure it (or rather the fact that we&#x27;re missing a huge chunk of it), but that doesn&#x27;t mean it&#x27;s &#x27;dark&#x27; or even &#x27;matter&#x27; or even one single thing.&quot;<p>It&#x27;s cool to hear about breakthroughs on the subject but as someone else said, at this point this article feels more like link-bait than anything concrete.<p>Maybe it&#x27;s just some folks who are incredibly stoked wanting to share before they have their ducks-in-row. So I&#x27;m not trying to say it&#x27;s intentional.<p>I&#x27;m just hungry for new information, and excited about it, so when it&#x27;s not all there I&#x27;m disappointed. Nerd problems, haha.

Very strange to see this article posted now. This news from the AMS is over a year old. And clearly, there is considerable debate whether the positron excess is from dark matter particle annihilation or from nearby pulsars. There are many papers on the subject - here is just one example that explains some of the issues - <a href="http://arxiv.org/pdf/1304.1840.pdf" rel="nofollow">http:&#x2F;&#x2F;arxiv.org&#x2F;pdf&#x2F;1304.1840.pdf</a> (PS - I am an astronomy graduate student).

Compatible with a dark matter particle on the order of 1 TeV - now just turn LHC back on, find a matching supersymmetric particle and give a welcome party for the 5th dimension.
