In an article for the latest issue of the Proceedings of the National Academy of Sciences Professor David Jablonski and Graduate Student Stewart Edie reveal a surprising fact about mass extinction events: the robustness of ecological variety that remains in the face of mass die-offs of species. Their research shows that despite the high number of species that die out during these types of events the 'functional diversity' of an ecosystem, i.e. the various modalities through which species survive relative to their ecosystem, remains fairly constant.

In the December 22nd edition of the Astrophysical Journal Professor Nicholas Dauphas lays out a comprehensive theory for how our solar system could have formed in the wind-blown bubbles around a giant, long-dead star. His work addresses a nagging cosmic mystery about the abundance of two elements in our solar system compared to the rest of the galaxy. The general prevailing theory is that our solar system formed billions of years ago near a supernova. But the new scenario instead begins with a giant type of star called a Wolf-Rayet star, which is more than 40 to 50 times the size of our own sun.
