Reading the chemicals on the wall

A writeup in ArsTechnica suggests a star recently studied has an anomalous abundance of elements [when did abundance stop meaning just lots and start to also mean some measurable amount?] which can be explained by this star being just one generation removed from the earliest stars from the big bang. If correct, this star is hugely more ancient than the other observable stars, which themselves are many cycles on in the birth, death and rebirth cycle which typifies all the stars we can study.
