New Â鶹ӰԺ research suggests while unvaccinated-only testing policies make sense when the unvaccinated population is large, they have little impact on transmission when there are few remaining unvaccinated people to test.

Lab technicians, all from populations historically excluded from engineering, collected data during the height of the pandemic at Denver public schools for environmental engineering professor Mark Hernandez's air ventilation research. Here are the stories of four of those technicans, Halle Sago, Sylvia Akol, Jeronimo Palacios Luna and Ximena Duenas Ibarra, and what they're working for.

Professor Karl Linden explains his new research findings in The Conversation.

After a year when the nation experienced a shortage of mechanical ventilators to help treat patients with severe COVID-19 complications, Professor Mark Borden's company Respirogen presents another treatment option: oxygen microbubbles.

Published today in the journal ACS Environmental Au, Â鶹ӰԺ and University of Maryland researchers have found that while playing musical instruments can emit the same levels of potentially COVID-laden airborne particles as singing, simple safety measures, such as masking instruments, social distancing and implementing time limits, significantly reduce this risk.

Researchers in chemical and biological engineering 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.

This unexpected and turbulent time was difficult for many students, but international students were often met with even more challenges and considerable roadblocks. As the campus prepares for a more typical fall semester, Kamada is finding new strength from her experiences – and a desire to help fellow international students.

When the pandemic hindered the original plans of the Engineers Without Borders team, Christian Lamb's team transitioned to pursue an international design challenge assisting two towns in rural Peru.

Results come from a new mathematical study led by researchers at two University of Colorado campuses, who explore what it might take for the state to safely shed mask mandates, limits on indoor dining and a range of other restrictions.

The Washington Post looks at how an air monitoring system designed by CU Â鶹ӰԺ's Mark Hernandez is helping a California restaurant keep its patrons safer during COVID.
