"New" bird-dinosaur study

The BBC is reporting a new bird-dinosaur study that reports developmental
evidence suggesting that the birds decended from dinosaurs hypothesis is
incorrect.  The researchers (N. Carolina, I believe) studied the development of
the "hand" in "birds" and "dinosaurs" (no species given in the report).  The
results indicate that fingers 2,3 & 4 comprise the bird "hand" (loss of 1 and
5) whereas fingers 1, 2 & 3 comprise the "theropod" hand (loss of 4 & 5). 
Again, no species were given.

As no reference was given in this radio summary, i can supply no further
details.  Has anyone seen this study?  Can you provide a reference or other
details as to the species involved?  Comments?
