Do people taste calcium?

By measuring the electrical activity of nerves linking the brain and tongue in mice, "we can now say with some certainty that calcium is tasted," Tordoff said.

There’s an interesting genetic story here, with a high-calcium mouse strain showing activity in a calcium receptor not previously known to be expressed in the tongue. Who knows what other things gene expression studies are going to find?
