Marginalized Americans are highly skeptical of artificial intelligence, research finds
Artificial intelligence may be marketed as society's great equalizer—transforming businesses, streamlining work and making life easier for all—but for many marginalized Americans, AI doesn't feel like a promise.
AI-powered ChronoFlow uses stellar rotation rates to estimate stars' ages
Figuring out the ages of stars is fundamental to understanding many areas of astronomy—yet, it remains a challenge since stellar ages can't be ascertained through observation alone. So, astronomers at the University of Toronto have turned to artificial intelligence for help.
A tiny satellite offers giant potential for unlocking cloud and energy flow mysteries
Beginning in the 1960s, satellite instruments have measured Earth's reflected broadband shortwave radiation and emitted longwave radiation. These measurements have been used to estimate Earth's "energy balance," defined as the difference at the top of the atmosphere between the
