As the evidence for nature’s health benefits continues to grow, the opportunities and challenges that stand before the park prescription movement are coming into sharper focus. What patterns in the research are emerging? How can prescriptions be fulfilled in the under resourced communities where they would do the most good? How do we institutionalize “nature as medicine” within policy at the municipal, state and national levels? This episode features the Founder of Park Rx America, Dr. Robert Zarr; Dr. Kathleen Wolf, a Research Social Scientist at the University of Washington; and Atiya Wells, a nurse and the Founder of Bliss Meadows, in a discussion of the ways the movement can gain broader adoption around the country.

Two national metrology institutes have conducted an international interlaboratory comparison on thermal conductivity for two thermal insulation reference materials. The Laboratoire national de métrologie et d’essais (LNE), France, and the National Institute of Standards and Technology (NIST), United States, present measurements obtained by the guarded-hot-plate method. The study involved two materials: expanded polystyrene board (EPS) and fibrous glass board (FGB). The EPS was provided by the LNE and is issued as a transfer specimen; the FGB provided by NIST was issued as Standard Reference Material (SRM) 1450c. For each reference material, the study was based on four independent measurements at a mean temperature of 24°C and two additional mean temperatures of 10°C and 35°C.
