Agreed - I have the very same issue as well. Google Keep is my goto mobile app for most of my note capture just due to its speed and ease of use. Now I have a few github utilities to download my Keep notes to markdown for Obsidian use later - but that isn't really ideal yet.

PS - all I can say about Canvas is 'wow'!!! Awesome feature!

Hmmmm...scientists are still debating whether the signal is dark matter or pulsar output (high energies create electron-positron pairs). I see this recent Chinese paper debating if DAMPE can even distinguish dark matter positron remnants or pulsars - Wang et al. (2017) say this - "For the pulsar case, the latest Fermi-LAT anisotropy limits have also been taken into account. Our results show that the cases of DM annihilations to τ+τ− and all charged leptons are difficult to be distinguished from the pulsar cases by the current experiments and DAMPE"

Philosophy Degrees: Reid Hoffman - LinkedIn, Stewart Butterfield - Flickr, Peter Thiel - PayPal, Patrick Byrne - Overstock, Carly Fiorina - you all know her, Carl Icahn - Icahn Enterprises, Sheila Bair - FDIC, George Soros - Soros Funds, Herbert Allison Jr. - Fannie Mae, Gerald Levin - Time Warner, Ethan Cohen - you all know him, Rupert Murdoch, Rashida Jones, Philip Glass, etc... ...of course - just statistical - there's always some list for other degrees too....

I think as the earlier comment pointed out this really was about the additional data from AMS that helps refine and/or add confidence to the possible theories - some of which are dark matter related and some which are not. Unfortunately, the article title was blatantly incorrect.

Excellent callout and my mistake missing the point on the wider energy range and the rollover. Thank you! The additional data will help the determination of dark matter vs. pulsars as the positron source.

"To determine if the observed new phenomenon is from dark matter or from astrophysical sources such as pulsars, AMS is now[sic] making measurements to determine the rate of decrease at which the positron fraction falls beyond the turning point (item 5), as well as to determine the antiproton fraction (the ratio of antiprotons to protons plus anti-protons). These will be reported in future publications."

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 - http://arxiv.org/pdf/1304.1840.pdf (PS - I am an astronomy graduate student).
