From Dave LeBlanc of Lagoon Island Pearls comes an amazing photograph of a mussel exploding with pearls.
Thank you Blaire, for including a scientific article in P-G's weekly showcase.
While big pearls are highly sought by aficionados everywhere, the greatest scientific data may be gleaned from the tiniest pearls. After all, a pearl scarcely a few days old is surrounded by evidence.
This work is critically important to dispel myths about pearl onset and formation. While it's understood pearls are formed by any combination of factors, this recent work entirely debunks many of the old wife's tales. Clearly, the pearls demonstrated in the article were formed in the absence of everything once thought true. There's no broken shells, no grains of sand, no parasites and no irritation, yet pearls formed in great numbers within the tissues of single specimens.
There's only so many hours in a day and pennies in a dollar to do advanced pathology in mollusks, but this article comes on the heels of some exciting news. I've been collaborating with Ana Vasiliu at the Stratigraphy and Paleontology lab at the U. of Granada, Spain for a few years now. Much of our work was cursory and general in nature, but given the speculations before us, we've been gradually gaining traction toward higher level research projects. What once were observations by eye and magnifying glass, evolved into scanning electron microscopy (SEM). In this manner, we've been able to document changes in nacreous structures. While these are after the fact observations, we've perked interest from the scientific community to observe these cellular modifications in real time, using transmission electron microscopy (TEM).
That's exciting news to a lowly field worker like myself who can on demand, produce adequate sampling material in a timely manner.
