New Scientist ran an article on this almost exactly a year ago:
They refer to the phenomenon as "retrocausality". Supposedly a set of
experiments were in the works to test the theory. A little quick
googling was not able to turn up any results, so I assume that they
did not, in fact, succeed in sending messages back in time...
