I agree. I was just re-reading a year-old article in Nature (May 1, 2003) about a quasar at z=2.701 that was in line with a damped Lyman alpha galaxy at z=2.62, so the absorption lines caused by the galaxy showed what elements were present in that galaxy. I guess this was publishable because they found approximately 25 elements, including a number of heavy elements such as zinc and germanium. The presence of these elements, particularly those heavier than iron, in such a young galaxy was termed "striking." John Cowan of the U. of Oklahoma, who summarized the paper, said "Their work opens a new window on the early formation of elements and stars in the Universe." Very cool stuff.
