Earth's oldest and biggest crater yields new secrets
LiveScience
Geologists say they've discovered rocks long thought vanished, the youngest remains of the oldest and biggest impact crater on Earth. In the abraded heart of South Africa's Vredefort impact crater lurk striking green-black rocks, some of the only remnants of a magma sea that once filled the gaping crater, according to a study. Until now, geologists thought nearly all of these "impact melt" rocks were lost to time.

MAP funding opportunities
GS
Are you planning or organizing a geochemistry workshop? Would you like some funding assistance? GS can help! The Geochemical Society Meeting Assistance Program (MAP) annually provides as many as five awards of up to US$ 2000 each to help support geochemistry sessions/symposia at any scientific conference of geochemical relevance. While this doesn't seem like a lot, the program is undersubscribed. So get those applications in! Full information on the (one page) application procedure can be found at http://www.geochemsoc.org/programs/meetingassistanceprogram/ (Submitted by Lesley Warren, Chair 2014 MAP Committee)

Rhode Island: Nitrogen cycle differs in bay and sound
ScienceDaily
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it's a major factor just a little farther out into Rhode Island Sound. Scientists traced that to differences between bay and sound sediments, but that raises new questions about what's going on in the Bay to account for those.

Missing piece of biogeochemical puzzle in aquifers discovered
ScienceDaily
New research may dramatically shift our understanding of the complex dance of microbes and minerals that takes place in aquifers deep underground. This dance affects groundwater quality, the fate of contaminants in the ground and the emerging science of carbon sequestration.

GEOS 2014 call for papers
GEOS
The 3rd Annual International Conference on Geological & Earth Sciences (GEOS 2014) will be held Sept. 22-23 in Singapore. The conference theme will orient on three broad and inter-related issues: the origin and evolution of the Earth through geological time span of about 4.55 Ga; the formation of earth resources and their distribution in space and time; and the earth processes in land-ocean-atmosphere interfaces. The submission deadline for papers is May 30. For more information visit http://www.geoearth.org/
