when they sampled it the first time, the douche bags sampled a section of the shroud that had been repaired in the 14 or 1500's . There was a fire that destroyed some sections. These sections were "rewoven" with 14 or 1500 string). DUHHH.
So, the recent "resampling was taken froma section that was NOT rewoven and was part of the roiginal cloth. This was dated to 60+ AD +/-120 yrs. (Ive seen several dates but all are in the realm of the ifetime of Jesus).
The "burst " of supernatural light and UV is more a result of (IMHO) symposia beverages than science.
The stains were subsampled and found to be organic Ferrous deposits (haem?) .
