Planck says that dark matter makes up 26% of the universe, while the best-fit WMAP number from a few years ago was 23%. This led me to joke on Twitter that we needed a model in which the dark matter density was rapidly increasing. Just a joke, people!
I hope to say something more substantive soon, but in the meantime there’s plenty of good stuff around the web; at the risk of leaving many people out, see Ethan Siegel, or Jester, or simply refuse to see the universe through anyone’s filter but your own and read the original papers. (An even thirty of them, helpfully indexed by the ultramodern system of Roman numerals.)
The comments on the YouTube page are nicer than average. Maybe it’s the British temperament.
