Actually ruthenium is part of the palladium series, not the platinum series. Its abundance is similar to that of molybdenum, platinum, gold, ... in fact, it is one of the common "impurities" in gold and platinum mining activities and could probably be obtained about as efficiently as those metals if there were sufficient demand.

One should, of course, also remember that there are hundreds of research groups pursuing similar goals worldwide and this one is not particularly different from many others. Perhaps the final result will be a biological system, or a pseudo-biological system?

PGMs are a mining term. it includes all those elements in that region of the periodic table because they have similar mining properties. they don't have truly minable ores (except Pt, and even that is not very concentrated) and are concentrated from other worked ores. for instance Re is mainly collected from Ni mining.

if there were cheap sources of any of them, they would be more widely used, just because of their myriad uses. Pt and Pd demand are close to world production. other PGMs? economically important curiosities..
