Study: Nitrogen fertilizer remains in soil, leaks toward groundwater for decades
A new study from scientists in France and at the University of Calgary has found that nitrogen fertilizer applied to crops lingers in the soil and leaks out as nitrate for decades toward groundwater.
Thirty years after synthetic nitrogen fertilizer had been applied to crops in 1982, about 15 percent of the nitrogen still remained in soil organic matter, the scientists found.

GS at GSA125
The GSA 125th Anniversary meeting is in full swing this week. If you are attending, be sure to visit the GS booth (1107) as well as attend the ticketed reception tonight (Tuesday, Oct. 29) from 5:45 - 7:45 p.m., CCC Upper Level Lobby D. As an affiliate of both GSA and AGI, A Geochemical Society representative was present at a AGI/GSA joint meeting that featured a presentation on AGI's new web resource the Center for Geoscience Education and Public Understanding. The center is a web service to the geoscience, education, and public communities. Although much of the content is U.S.-centric there are resources to benefit to the international community.

Free introductory student memberships
In early-2013, the GS introduced as a part of its International Participation Program free two-year student memberships to students from countries that are under represented in the GS. At this time, 69 memberships have been granted to students from 17 different countries.
If you are a student in a qualifying country, or know someone who is, and are not already a GS member, the 2014 application for introductory student membership is now open. In 2013, the program was supported by generous donations from 18 society members along with a contribution from the GS. 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 be able to introduce 100 students or more to the field of geochemistry in 2014.

Carbon Sequestration Short Course
Given the public's interest and concern over the impact of atmospheric greenhouse gases (GHG) on global warming and related climate change patterns, this MSA/GS short course and accompanying Reviews in Mineralogy and Geochemistry volume 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 will be held at the Lawrence Berkeley National Laboratory on Dec. 7-8, 2013 in conjunction with the 2013 Fall AGU meeting. Online registration is now open and limited to 110 participants. Discounted rates are available for members, and participants who register by Nov. 4, 2013. The course convenors are Donald DePaolo, David Cole, Alexandra Navrotsky and Ian Bourg.

Meteorite study suggests Mars atmosphere trapped in rocks, not lost in space
The atmosphere of Mars may not have escaped into space billions of years ago, scientists say. Instead, the bulk of Mars' carbon dioxide gas could be locked inside Martian rocks. Most of Mars' carbon dioxide vanished about 4 bildflion years ago, leaving a cold planet covered in a thin veneer of gas.
Gold in trees leads to hidden deposits
Money might not grow on trees, but scientists have confirmed that gold is found in the leaves of some plants.
Researchers from Australia say that the presence of the particles in a eucalyptus tree's foliage indicates that deposits are buried many meters below.
They believe that the discovery offers a new way to locate the sought-after metal in difficult-to-reach locations.
Earth's core deceives scientists
Scientists have virtually denied the existing hypothesis about the formation of the Earth's core. It was believed that the metal core of all celestial bodies is formed under the same scheme. However, recent experiments demonstrated that there are other ways to form the core. It turns out that this process should be seen as unique to each celestial body.
