New Science Center Exhibit

Meanwhile, a new exhibit opens Friday at the Pacific Science Center, which is at the Seattle Center. It showcases the work of University of Washington oceanographer Deborah Kelley who studies hydrothermal vents and underwater volcanoes.

Her exhibit is in the Portal to Current Research space that features local scientists.

No ap for that. Yet, anyway.
