A reaction on a single electrode can tell scientists a remarkable amount about the chemical nature and number of analytes involved. The challenge comes when they want to distinguish many reactions on the same electrode. After more than a decade of trying to overcome that limitation, Ravi Saraf and his Nebraska Engineering graduate students have demonstrated a way to quantify many reactions on the same electrode without sacrificing extraordinary sensitivity.

Faraway tectonic forces may have accelerated the Gulf of California rifting
When the Baja California peninsula broke from mainland Mexico nearly 12 million years ago, it gave rise to the Gulf of California. New research suggests that this process of continental rifting was greatly accelerated due to tectonic forces on the opposite side of the Pacific Oce
