We’re not so different: Bacterial weapons could help fight human diseases

Feb. 8, 2023

A new study reveals that bacteria and people share the same core machinery for fighting off viruses and sheds light on how that ancient machinery works. The discovery could lead to novel treatments for human diseases, much like the gene-editing tool CRISPR—also modeled after a bacterial weapon—has.

UV light

Ultraviolet light can annihilate COVID-19 aerosols, but there’s a tradeoff with air quality

Dec. 15, 2022

A new CIRES-led study finds germicidal ultraviolet light disinfection can be used to fight COVID-19 in high-risk environments. However, the technique produces harmful secondary chemicals in indoor air, with a significant but not overwhelming impact. There are multiple strategies that can be used to minimize the air quality impact, which are now under investigation.
