Underscoring the effect of swab type, workflow, and positive sample order on swab pooling for COVID-19 surveillance testing by Maxwell J. Kalinowski, Devon R. Hartigan, Neal M. Lojek, Bryan O. Buchholz, Chiara E. Ghezzi

“…We investigated the performance of several commercially available swabs (Steripack polyester flocked, Puritan nylon flocked, Puritan foam) in comparison to a new injected molded design (Yukon). The bench-top performance of collection swab was conducted with a previously developed anterior nasal cavity tissue model, based on a silk-glycerol sponge to mimic soft tissue mechanics and saturated with a physiologically relevant synthetic nasal fluid spiked with heat-inactivated SARS-CoV-2. …”

Smoke injection heights from fires in North America: analysis of 5 years of satellite observations by M. Val Martin, J. A. Logan, R. A. Kahn, F.-Y. Leung, D. L. Nelson, D. J. Diner

“…The analysis of plume heights in combination with assimilated meteorological observations from the NASA Goddard Earth Observing System indicates that a significant fraction (4–12%) of plumes from fires are injected above the boundary layer (BL), consistent with earlier results for Alaska and the Yukon Territories during summer 2004. Most of the plumes located above the BL (>83%) are trapped within stable atmospheric layers. …”
