LabX is the public engagement testbed at the U.S. National Academy of Sciences (NAS) - currently located in Washington, D.C. From 2004 until 2017, it was known as the Marian Koshland Science Museum. The museum featured exhibits that presented modern science and scientific issues in an accessible way, geared for the general public. It explored current scientific issues that were important for the nation's and world's public policy decisions, as presented in reports by the United States National Academies. The National Academy of Sciences replaced the museum with LabX.
