Tend to get sick when the air is dry? New research helps explain why
Airborne particles carrying a mammalian coronavirus closely related to the virus which causes COVID-19 remain infectious for twice as long in drier air, in part because the saliva emitted with them serves as a protective barrier around the virus, especially at low humidity levels.

Mutation-mapping tool could yield stronger COVID boosters, universal vaccines
2022 Silver Pick Award: Public Relations Society of America, Colorado Chapter Researchers have developed a platform which can quickly identify common mutations on the SARS-CoV-2 virus that allow it to escape antibodies and infect cells. The research marks a major step toward successfully developing a universal vaccine for not only COVID-19, but also potentially for influenza, HIV and other deadly global viruses.

Not a moment to waste
Since 23 sewer sampling stations were first installed and turned on in August of 2020, a team of 35 undergrads, graduate students and alumni have collected over 3,000 samples and run more than 4,700 tests over at least 140 days. These snapshots of what’s in our wastewater have been critical to keeping campus safe during the pandemic—and systems like it could even help us catch the next one. CU Boulder Today April 1, 2021 |

Singing unmasked, indoors spreads COVID-19 through aerosols, new study confirms
Singing indoors, unmasked can swiftly spread COVID-19 via microscopic airborne particles known as aerosols, confirms a new peer-reviewed study of a March choir rehearsal which became one of the nation’s first superspreading events. "The research adds to the overwhelming body of evidence that aerosol transmission is playing a major role in driving this pandemic and especially to superspreading events,” said Jimenez.
