A specific wavelength of ultraviolet light is not only extremely effective at killing the virus that causes COVID-19, but is also safer for use in public spaces, finds new CU Â鶹ӰԺ research.

Roy Parker and Kristen Bjorkman review the status of the COVID-19 delta variant in the United States, the latest data on vaccines and breakthrough cases, and more.

While playing musical instruments can emit potentially COVID-19-laden airborne particles, researchers have found that simple safety measures, such as masking instruments, social distancing and implementing time limits, significantly reduce this risk.

Researchers have developed a platform that can quickly identify common mutations of the SARS-CoV-2 virus, which could inform the development of more effective booster vaccines and tailored antibody treatments for patients with COVID-19.

Experts answer your questions about the delta variant of the coronavirus—from whether vaccines lose their efficacy over time to how common breakthrough cases are among the vaccinated.

A new variant of the virus that causes COVID-19 is now behind nearly 90% of the cases in the state. Researchers from CU Â鶹ӰԺ talk about this new player in the pandemic and whether vaccinated people should continue to wear masks in public.

Kids around Colorado are kicking back for summer vacation. But one team of engineers is working to make sure when children come back to school in the fall, the air they breathe will be cleaner and healthier.

Shelly Miller and her colleagues have been at the forefront of research on how SARS-CoV-2 spreads through tiny airborne particles. Their studies have led to the creation of safety protocols for singing and playing musical instruments.

Some worry the science was rushed. Others question whether the benefits outweigh the risks. Here's what Teresa Foley, a teaching professor of distinction in integrative physiology, tells students, acquaintances and family who are hesitant.

CU Â鶹ӰԺ is collaborating with the Association of American Universities and others on a series raising awareness about the role of public research universities in times of significant global challenges. In CU Â鶹ӰԺ's clip, an environmental engineering team is working with schools to improve air filtration.
