Voting is now open for the People's Choice award in Pacific Northwest National Laboratory's 2017 Science as Art contest. Polls will close at 5:00 p.m. on Sept. 22. To vote, simply visit the PNNL Facebook page and "like" your favorites to give them a shot at winning the People's Choice award.

More than 90 photos and images were submitted by PNNL staff during the laboratory's seventh Science as Art contest this summer.

The submissions cut across a wide range of disciplines and projects, from research examining how microbes living on ancient glass from the Swedish Iron Age are helping us better understand methods for disposing of nuclear waste, to studies into how plant biomass can be converted into sustainable fuel alternatives.

Top images from contests in previous years have been displayed all across Washington state including the Pacific Science Center in Seattle, the Washington State Capitol Building in Olympia, the WSU Tri-Cities campus and LIGO Hanford Observatory in Richland.
