It's not exactly breaking news, but this post at the Evilutionary Biologist blog has an interesting take on what happened in the science of DNA structure immediately after Watson and Crick published their now-famous model. "The race was on to empirically demonstrate its correctness because, in fact, Watson and Crick's model had precious little going for it other than the fact that it was so damned pretty," writes John Denney. He chronicles the work of Matt Meselson and Frank Stahl, who used E. coli in their creative efforts to prove the model.
