The only thing I could find in the last year or so was a study of mitochondrial DNA which suggests that the Minoans were descended from the Neolithic settlers of Europe (like most modern Europeans).

The script itself, though, is most likely already deciphered. Many (but not all) of the individual characters are present in Linear B, which is pretty obviously descended from Linear A. There's no evidence to suggest that the character signs have different values in the two scripts.

Nobody's sure what language Linear A is recording, though. In part this is because of the nature of the texts (mostly accounting) and in part because there isn't that much material. It's been suggested by respectable scholars that the Minoan language is unrelated to any known language, that it's in the Semitic family and that it's related to Luwian.

Andrew Robinson's Lost Languages has a good chapter on Linear A. John Younger at Kansas has a nice page with a summary of the state of the knowledge on Linear A and phonetic transcriptions.
