“Using the oldest fossil micrometeorites -- space dust –
ever found, new research has made a surprising
discovery about the chemistry of Earth's atmosphere
2.7 billion years ago.”

The paper is:

Tomkins, A. G., L. Bowlt, M. Genge, S. A. Wilson, H. E. A.
Brand, and J. L. Wykes, 2016, Ancient micrometeorites
suggestive of an oxygen-rich Archaean upper atmosphere.
Nature, 2016; 533 (7602): 235 DOI: 10.1038/nature17678
http://www.nature.com/nature/journal/v533/n7602/full/nature17678.html

Off-topic, but a break from the daily gloom and doom.
