A first-of-its-kind instrument that samples smoke from megafires and scans humidity will help researchers better understand the scale and long-term impact of fires—specifically how far and high the smoke will travel, when and where it will rain, and whether the wet smoke will warm the climate by absorbing sunlight.
Moderate temperature increases broke down SARS-CoV-2 virus-like particles structure on glass surfaces, suggesting that virus particles on surfaces will remain infectious longer. The findings agree with observations of other coronaviruses that appear to infect more people during the winter.
The novel coronavirus that causes COVID-19 is thought to spread through natural respiratory activities, but little is known about how the virus is transported through the air. Scientists report in Physics of Fluids on a study of how airflow and fluid flow affect exhaled droplets that can contain the virus. Their model includes a more accurate description of air turbulence that affects an exhaled droplet’s trajectory. Calculations with their model reveal, among other things, an important and surprising effect of humid air.
New Brunswick, N.J. (July 20, 2020) – Rutgers University–New Brunswick climatologist David A. Robinson is available for interviews on the ongoing heat wave in New Jersey and the hot summer weather to date. The worst of the heat wave is expected today,…
One of the biggest unknowns about coronavirus is how changing seasons will affect its spread. Physicists from the University of Utah have received a NSF grant to create individual coronavirus particles without a genome. They’ll test how the structure of the coronavirus withstands changes in humidity and temperature.
Heat stress from extreme heat and humidity will annually affect areas now home to 1.2 billion people by 2100, assuming current greenhouse gas emissions, according to a Rutgers study. That’s more than four times the number of people affected today, and more than 12 times the number who would have been affected without industrial era global warming.
If you guessed locations with drier atmospheres and frequent clear skies, you’re right. WASHINGTON, D.C., June 25, 2019 — A group of University of California, San Diego researchers set out to gain a better understanding of the thermal balance of…
