I welcome well-founded scientific articles about the Shroud of Turin like this, as I have read many unsubstantiated claims, both on one side and another: believers see traces of Roman coins laid on the eyes, and skeptical conjecture phantasies about weird ways a super-intelligent forger could have laid the paint on the Shroud.
However, the article fails to mention some details that make the matter not settled, at least in my opinion.
First, the position of the holes in the hands differs from the common belief at the time. Virtually all Western Art depicts the nails entering the palm, yet the man of the Shroud has holes in his wrists. Experiments on dead bodies done in the XIX century demonstrated that only when the nail is put in the wrist the weight of the body can be sustained, but this was unknown in the XIV century. Moreover, there is a nerve in the wrist that, when injured, causes the thumb to retract; this, too, is consistent with the Shroud but differs from the common imagery used in the Middle Ages. (See, for instance, Grünewald’s Crucifixion [1].)
Second, the article fails to mention a paper by Rogers (2005) [2] that applied a non-invasive form of dating to the Shroud. According to these results, the borders of the Shroud are younger than the part in the center (where the image was impressed) and were probably patches added to repair the damage of a burning. This seems to be confirmed by microscopic analysis of the fibers of the samples used in the C14 tests, which do not match the images of the parts of the Shroud that contain the image. Unfortunately, the author states that his dating technique is powerful for relative dating but not absolute dating because of the large error bars. Thus, Rogers could not provide reliable dating.
The most significant difficulty in believing the Shroud’s authenticity is the lack of documentary sources in the first Millennium. However, unlike the author seems to believe, the question might not have been settled definitively by the C14 measurement.
