From the New York Times:

A faded fragment of papyrus known as the “Gospel of Jesus’s Wife,” which caused an uproar when unveiled by a Harvard Divinity School historian in 2012, has been tested by scientists who conclude in a journal published on Thursday that the ink and papyrus are very likely ancient, and not a modern forgery.
Skepticism about the tiny scrap of papyrus has been fierce because it contained a phrase never before seen in any piece of Scripture: “Jesus said to them, ‘My wife…’ ” Too convenient for some, it also contained the words “she will be able to be my disciple,” a clause that inflamed the debate in some churches over whether women should be allowed to be priests.
The papyrus fragment has now been analyzed by professors of electrical engineering, chemistry and biology at Columbia University, Harvard University and the Massachusetts Institute of Technology, who reported that it resembles other ancient papyri from the fourth to the eighth centuries. (Scientists at the University of Arizona, who dated the fragment to centuries before the birth of Jesus, concluded that their results were unreliable.)
The test results do not prove that Jesus had a wife or disciples who were women, only that the fragment is more likely a snippet from an ancient manuscript than a fake, the scholars agree. Karen L. King, the historian at Harvard Divinity School who gave the papyrus its name and fame, has said all along that it should not be regarded as evidence that Jesus married, only that early Christians were actively discussing celibacy, sex, marriage and discipleship.

An initial radiocarbon analysis dated the fragment to 404–209 BC; a second analysis gave a mean date of AD 741. King concludes with a date in the 7th or 8th centuries AD. As far as being a reliable witness to 1st century events, it is not. The author notes that the fragment should be studied in light of the Muslim view that prophets were usually married.

In King’s reading, “The main point of the GJW fragment is simply to affirm that women who are wives and mothers can be Jesus’s disciples.”

A new article in the Open Journal of Geology strengthens the case for the authenticity of the inscription on the James Ossuary. The article was written by Amnon Rosenfeld, Howard R. Feldman, Wolfgang E. Krumbein and is available for free download. The abstract gives a sense for the technical detail involved in the study.

An archaeometric analysis of the James Ossuary inscription “James Son of Joseph Brother of Jesus” strengthens the contention that the ossuary and its engravings are authentic. The beige patina can be observed on the surface of the ossuary, continuing gradationally into the engraved inscription. Fine long striations made by the friction of falling roof rocks continuously crosscut the letters. Many dissolution pits are superimposed on several of the letters of the inscription. In addition to calcite and quartz, the patina contains the following minerals: apatite, whewellite and weddelite (calcium oxalate). These minerals result from the biogenic activity of microorganisms that require a long period of time to form a bio-patina. Moreover, the heterogeneous existence of wind-blown microfossils (nannofossils and foraminifers) and quartz within the patina of the ossuary, including the lettering zone, reinforces the authenticity of the inscription.
