CU Boulder Today chatted with Jose-Luis Jimenez, chemistry professor and CIRES fellow, about why it’s so important to wear a face covering—even when you’re outdoors.

Researchers have set up a network to monitor the wastewater leaving residence halls on campus as part of an effort to detect and intercept community spread of COVID-19.

As students return to campus, a mostly behind-the-scenes team of university staff and scientists has been working to make sure that the air they breathe will be as safe as possible.

Before ever entering a residence hall, students moving to campus will spit in a tube, hand it over and wait just 45 minutes for their COVID-19 test results.

The Internet Research Agency, a troll-farm based in St. Petersburg, reached out to thousands of Twitter users in the lead up to the 2016 presidential election. Afterward, some may have changed their behavior online.

Researchers from the BioFrontiers Institute at CU Boulder have developed a saliva-based COVID-19 test capable of returning results in as little as 45 minutes—no nasal swabs or fancy laboratory equipment required. It could potentially be used for mass, inexpensive screening in community settings like schools and factories.

A CU Boulder researcher has received National Science Foundation funding to study COVID-19 spread in airplane cabins.

After 239 scientists signed on to a letter arguing that the coronavirus can go airborne, the World Health Organization updated its public health guidelines.

If each human cell has the same blueprint, or set of genes, why does an eye cell look and act differently than a brain cell or skin cell? New research moves science one step closer to solving this mystery, potentially leading to new treatments for cancer, heart abnormalities and more.

As many as 7% of moms-to-be use marijuana while pregnant, and that number is rising fast as more use it as a remedy for morning sickness. But new research shows such use could have a lasting impact on the fetal brain, influencing children's sleep for as much as a decade.
