ATP is a major determinant of phototrophic bacterial longevity in growth arrest.

L. Yin, H. Ma, E. M. Fones, D. Morris, C. S. Harwood

This study shows that ATP depletion leads to cell death in Rhodopseudomonas palustris during growth arrest, while ATP-replete conditions allow long-term survival.

Comparative aerosol and surface stability of SARS-CoV-2 Variants of Concern

T. Bushmaker, K. C. Yinda, D. Morris, M. Holbrook, A. Gamble, D. Adney, C. Bushmaker, N. van Doremalen, R. Fischer, R. Plowright, J. O. Lloyd-Smith, V. Munster

This study compares aerosol and surface stability of SARS-CoV-2 variants, finding early VOCs more stable than WA1, but Delta and Omicron do not show increased stability, suggesting stability changes are not the main driver of transmissibility.
