Fantastic story of a "big picture" in science which might explain three different puzzles of the recent geologic past, near the end of the most recent ice age, 12,900 years ago. I love it when dramatic science stories make the cut and this is no exception. Who knows if the postulated theory (comet explosion) is the cause or not? Maybe it is, maybe not. That's the way of science.

Good brief overview of what may turn out to be of great importance in many branches of earth and social sciences. Leaves one eagerly awaiting more detail and analysis. It's also a good, factual story that reminds us there are other truly immense issues we must not go to sleep on.

This is basic reporting about a report yet to be issued. It lacks any real meat but alludes to a theory that will ultimately rise to acceptance within the scientific community or not. Time will tell. Until then it is just interesting conjecture.

Certainly an interesting story, seemingly plausible. Article doesn't question what else might have caused the "microdiamonds" and whether they formed at the same time, but this may have been addressed by the scientists, and they admit it's work in progress.
