GREENWICH — The Bruce Museum honored 10 area high school students recently for their outstanding research as part of its Phenomenon Science Innovation Fair.

First prize went to Raina Jain for her project “Magnetically Induced, Visual Detection of Trace Arsenic Contaminants in Water Using Fe3O4 Photonic Crystal Structures.” Her system can detect arsenic contamination at 10 parts per billion compared to existing tests that only reach 250ppb. Since the threshold for human danger is 100ppb, this is a great advance.
