Time's featuring an excellent article on the James ossuary. It's part detective work (the limestone was quarried from the range that hosts the Mount of Olives) and part statistical analysis (the probable number of James/Joseph/Jesus families in Jerusalem around 63 AD is calculated to be ~20) it makes for good reading.
By far, the most exciting aspect -- and one that I hadn't seen reported yet -- is the presence of bone chips in the soily bottom of the box. However remote, the possibility that the chips could be James' is fascinating: direct DNA evidence of the existence of an historical Jesus, via the maternal link of Mary. Wow.
