Using a new method to detect trace elements in tree rings, researchers at Cornell University and Penn State noticed elevated amounts of gold in specific rings and correlated several of the bands to a number of volcanic eruptions over the past 500 years. 

Penn State nuclear engineer Kenan Unlu, Cornell tree-ring expert Peter Kuniholm and their colleagues believe they can use the technique not only to confirm known eruptions and other phenomena, but also to detect those events when other climatic and geologic records are missing.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2014, its budget is $7.2 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
