Andy Fell — August 26, 2024

Figuring out the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world’s most sensitive dark matter detector, LUX-ZEPLIN (LZ), have narrowed down possibilities for one of the leading dark matter candidates: weakly interacting massive particles, or WIMPs.

How Uncertainty Builds Anxiety

Andy Fell — June 25, 2024

Alfred Hitchcock observed that “There is no terror in the bang, only in the anticipation of it.” A common way to build suspense in a movie scene is for the audience to know something bad is going to happen, but not when it is going to happen. But how does uncertainty work to ratchet up our anxiety? In a recent paper in the journal Computational Psychiatry, researchers at the ��С��, Davis, Department of Psychology take a deeper look into what builds fear.
