Three years after the first cases of COVID-19 emerged, scientists have a far better understanding of how it spreads, how to prevent infection and minimize symptoms, and what needs to be done to prevent the next pandemic.

New technologies are often surrounded by hopeful messages that they will alleviate poverty and bring about positive social change. History shows these assumptions are often misplaced. Three experts discuss in The Conversation podcast.

Hisham Ali is pushing the limits of plasma physics and hypersonics in his lab on campus to advance a nationally important area of science and engineering: magnetohydrodynamics.

Tens of thousands of sharks are killed each year to harvest a key ingredient for vaccines, while old growth trees are slashed to obtain chemotherapy ingredients. Soybean farmer-turned molecular biologist Brian DeDecker has a better idea.

The Acoustic Gym, designed by a team of biologists and engineers at ¶¶Òõ¶ÌÊÓƵ Boulder, is about the size of a quarter and uses sound waves to generate small whirlpools—the perfect place for tiny worms to get in their laps.

1,200 years ago on the isolated island of Madagascar, giant flightless elephant birds roamed the landscape. Research using ancient eggshell fragments reveals new clues about their genetic diversity.

A study finds that those on the ¶¶Òõ¶ÌÊÓƵ Boulder and Colorado State University campuses showed high levels of mask use and positive attitudes about masks during pandemic.

New ¶¶Òõ¶ÌÊÓƵ Boulder research finds that overweight populations have a 22% higher mortality risk than those of healthy weight, while obese populations have as much as double the risk. The study found that about 1 in 6 adult deaths in the U.S. are related to excess weight or obesity.

¶¶Òõ¶ÌÊÓƵ Boulder researchers have found that airborne coronavirus remains infectious for twice as long in drier air—in part because saliva serves as a protective barrier around the virus, especially at low humidity levels.

Roughly 1,000 years ago, ancient peoples carried more than 200,000 heavy timbers entirely on foot to a site in the modern-day Four Corners region called Chaco Canyon. ¶¶Òõ¶ÌÊÓƵ Boulder researchers think they know how such a feat of human endurance may have been possible.
