Definitely people are working, but we dont have an addition to our methods of something fundamental. The papers you re referencing provide interesting conceptual theories, but none of them will survive for decades the way Hodkin-huxley's or Rall's models did. A lot of work on dendrites goes back to the 90s (e.g. seminal work of Mel http://www.nature.com/neuro/journal/v7/n6/abs/nn1253.html http://www.nature.com/neuro/journal/v7/n6/abs/nn1253.html) and we still dont have a convincing theory of what they do.
