Rising sea levels 20,000 years ago, as the last ice age was beginning to wane, often are attributed in part to melting in West Antarctica. But in a new study led by University of Washington researchers, an ice core of 1,000 meters was used as a sort of dipstick to show that a key......al forhealthy nerve cells.
