The <a href=\"http:\/\/press.web.cern.ch\/press-releases\/2013\/04\/ams-experiment-measures-antimatter-excess-space\">press release<\/a> has:<\/p>\n<blockquote><p>The international team running the Alpha Magnetic Spectrometer (AMS1) today announced the first results in its search for dark matter&#8230;.<\/p>\n<p>These results are consistent with the positrons originating from the annihilation of dark matter particles in space, but not yet sufficiently conclusive to rule out other explanations&#8230;.<\/p>\n<p>One possibility, predicted by a theory known as supersymmetry, is that positrons could be produced when two particles of dark matter collide and annihilate. Assuming an isotropic distribution of dark matter particles, these theories predict the observations made by AMS&#8230;\n<\/p><\/blockquote>\n<p>which, is inconclusive if you read it carefully, but sure makes it sound like this was an announcement of significant evidence for dark matter if you don&#8217;t.
