Interstellar molecules are branching out
Max Planck Institute for Radio Astronomy
Scientists from the Max Planck Institute for Radio Astronomy, Cornell University, and the University of Cologne have for the first time detected a carbon-bearing molecule with a "branched" structure in interstellar space. The molecule, iso-propyl cyanide, was discovered in a giant gas cloud called Sagittarius B2, a region of ongoing star formation close to the center of our galaxy that is a hot-spot for molecule-hunting astronomers.
Broadening the Diversity of Excellence
In the next few weeks we face the deadlines for submission of nominations for the GS's highest competitive honors (Oct. 31). Having the most deserving and most diverse group of award winners is important for many reasons. Awardees symbolize the highest achievement in our field. They inspire all of us, and especially those at an early career stage, to do our best science. They become among the most visible spokespersons for our profession.
Introductory Student Membership Program
In early-2013, the GS introduced the Introductory Student Membership program which grants a two-year membership to students from countries that are under represented in the Geochemical Society. To date, this program has granted 91 memberships to students in 18 countries. If you are a qualifying student, please consider applying. If you know of students in your department or those of collaborators who you think would benefit from the free GS memberships, please encourage them to apply. And finally, if expanding the reach and support for geochemistry internationally is important to you, please consider donating to this program. Donations can be directed to this fund either at the time of membership renewal or by completing your member login and clicking the donate link. With your support, we hope to introduce 100 students or more to the field of geochemistry in 2015.
Analab manufacture corrosion resistant laboratory appliances such as acid vapour cleaning stations, hotplates, and sample preparation devices. Our devices can be used with a wide range of acids and bases (HF to NH4OH). We are represented in North America by Isomass Scientific.
Please visit us at GSA 2014 in Vancouver, Booth 1018.

Study: Earth's ocean abyss has not warmed, NASA
NASA/Jet Propulsion Laboratory via ScienceDaily
The cold waters of Earth's deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of why global warming appears to have slowed in recent years. But scientists say these findings do not throw suspicion on climate change itself.
Scientists: Ocean warming in Southern Hemisphere underestimated
DOE/Lawrence Livermore National Laboratory via ScienceDaily
Using satellite observations and a large suite of climate models, scientists have found that long-term ocean warming in the upper 700 meters of Southern Hemisphere oceans has likely been underestimated. Ocean heat storage is important because it accounts for more than 90 percent of Earth's excess heat that is associated with global warming.
