Actually, it hasn't been quiet at all. Since about October 1995, string
theorists seem to be agreed that all five forms of string theory (bosonic,
Types I, IIa, IIb, heterotic) are different limits of one underlying
theory, "M-theory", which is a theory of interacting _membranes_
(fundamental objects of two or more dimensions) in eleven-dimensional
spacetime.

As for connection to experiment, a lot of papers on string phenomenology
are being written, but the theory doesn't yet have a major predictive
success which it can claim as uniquely its own.
