CU Â鶹ӰԺ 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. CU Â鶹ӰԺ researchers think they know how such a feat of human endurance may have been possible.

In a new study, CU Â鶹ӰԺ astrophysicist Erica Nelson and her colleagues spotted six "fuzzy dots" of light in images from the James Webb Space Telescope. The candidate galaxies may have existed just 500 to 700 million years after the Big Bang and contain almost as many stars as the Milky Way.

Artificial intelligence has reached an "inflection point," according to technology experts from CU Â鶹ӰԺ. New tools like ChatGPT, which rolled out late last year, are poised to transform offices, high school classrooms and more—in potentially good and bad ways.

Enjoy a Q&A with Professor Ahmed White, whose new book gives a dramatic, deeply researched account of how legal repression and vigilantism brought down the Wobblies, and how the destruction of their union haunts us to this day.

Mike DelPrete, a scholar in residence at the Leeds School of Business, says new tools will bring incremental changes, not wide-scale disruption.​

Jennifer Ho, director of CU Â鶹ӰԺ’s Center for Humanities & the Arts, discusses the state of the arts and humanities in higher education as CHA celebrates its 25th anniversary.

A geologist and an engineer discuss what made the recent earthquake in Turkey and Syria so devastating, how the region shares similar geology with California and how lessons learned can help the world prepare for the next big one.

Video footage can play a crucial part in cases such as the fatal beating of Tyre Nichols. Depending on how the evidence is presented, among other factors, jurors can perceive events in a video in different ways. CU expert Sandra Ristovska explains on The Conversation.

A study co-authored by a CU Â鶹ӰԺ professor suggests biased jury decisions are associated with social cognitive processes such as cultural and racial stereotyping.
