Recent work by Anne McCoy and coworkers published in Science

McCoy 2015 editWater conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades.

But in a paper published in the Dec. 2 issue of the journal Science, an international team of researchers has finally caught water in the act — showing how water molecules pass along excess charges and, in the process, conduct electricity.

“This fundamental process in chemistry and biology has eluded a firm explanation,” said co-author Anne McCoy, professor of chemistry. “And now we have the missing piece that gives us the bigger picture: how protons essentially ‘move’ through water.”

The team was led by Mark Johnson, senior author and a professor at Yale University. For over a decade, Johnson, McCoy and two co-authors — Professors Kenneth Jordan at the University of Pittsburgh and Knut Asmis at Leipzig University — have collaborated to understand how molecules in complex arrangements pass along charged particles.
