New approach to explaining evolution's big bang
The New York Times
The name Myllokunmingia may not ring a bell, but it is worth knowing. This 520-million-year-old creature was the size of a guppy, with a tiny swordfish-like fin running high over its back. The fossils it has left behind preserve traces of a skull. Humans have a skull, too. This and a number of other traits we share with Myllokunmingia reveal it to be one of the oldest, most primitive vertebrates yet found. It is, in other words, a hint of where we came from.

Call for Award Nominations
2014 Award Nominations are due Oct. 15. Through the committed efforts of the 2014 Award Nomination committee, whose sole task is to reach out to the community to identify and solicit nominations for worthy award candidates, we have made strides in increasing the number of nominations, but we still need your help. The award committees cannot select candidates who are not nominated, so as we urged right after Goldschmidt2013, and again with regard for the need for nomination diversity, please help make a difference by submitting a nomination. And thank you to those who have already submitted nominations or are in preparations, your nominations are invaluable to the process.

CO2 Sequestration Short Course
Early registration ends on Oct. 7 for the Reviews in Mineralogy and Geochemistry Short Course Geochemistry of Geological CO2 Sequestration held at the Lawrence Berkeley National Laboratory on Dec. 7-8 in conjunction with the AGU Fall Meeting. GS Members benefit from a member discount ($20 off for student members, $80 off for professional members). The short course aims to provide an authoritative summary of the fundamental geochemical and mineralogical processes associated with gas-water-mineral-interactions encountered during geological sequestration of CO2. The course convenors are Donald DePaolo, David Cole, Alexandra Navrotsky and Ian Bourg.

Geologists simulate deep earthquakes in the laboratory
TG Daily
More than 20 years ago, geologist Harry Green, now a distinguished professor of the graduate division at the University of California, Riverside, and colleagues discovered a high-pressure failure mechanism that they proposed then was the long-sought mechanism of very deep earthquakes (earthquakes occurring at more than 400 km depth). The result was controversial because seismologists could not find a seismic signal in the Earth that could confirm the results. But seismologists have now found the critical evidence.
