Shotgun Metagenomics Reveals Taxonomic and Functional Shifts in Hot Water Microbiome Due to Temperature Setting and Stagnation

Dai, Dongjuan; Rhoads, William J.; Edwards, Marc A.; Pruden, Amy (Frontiers, 2018-11-13)

Hot water premise plumbing has emerged as a critical nexus of energy, water, and public health. The composition of hot water microbiomes is of special interest given daily human exposure to resident flora, especially ...

Characterization and prediction of tropical cyclone forerunner surge

Liu, Yi; Irish, Jennifer L. (Elsevier, 2019)

Forerunner surge, a water level rise ahead of tropical cyclone landfall, often strikes coastal communities unexpectedly, stranding people and increasing loss of life. Surge forecasting systems and emergency managers almost ...

Mechanistic insights into the effect of humidity on airborne influenza virus survival, transmission and incidence

Marr, Linsey C.; Tang, Julian W.; Van Mullekom, Jennifer; Lakdawala, Seema S. (Royal Society Publishing, 2019-01-16)

Influenza incidence and seasonality, along with virus survival and transmission, appear to depend at least partly on humidity, and recent studies have suggested that absolute humidity (AH) is more important than relative ...

Nanomaterial enabled sensors for environmental contaminants

Willner, Marjorie R; Vikesland, Peter J (2018-11-22)

Abstract The need and desire to understand the environment, especially the quality of one’s local water and air, has continued to expand with the emergence of the digital age. The bottleneck in understanding ...

Influenza Virus Infectivity Is Retained in Aerosols and Droplets Independent of Relative Humidity

Kormuth, Karen A.; Lin, Kaisen; Prussin, Aaron J.; Vejerano, Eric P.; Tiwari, Andrea J.; Cox, Steve S.; Myerburg, Michael M.; Lakdawala, Seema S.; Marr, Linsey C. (Oxford University Press, 2018-06-07)

Pandemic and seasonal influenza viruses can be transmitted through aerosols and droplets, in which viruses must remain stable and infectious across a wide range of environmental conditions. Using humidity-controlled chambers, ...
