The Collective Power of the Solar System's Dark, Icy Bodies
Published: July 07, 2020

Within our solar system are icy planetary bodies that do not orbit the Sun. JILA Fellow Ann Marie Madigan's group suggest that these detached objects have steadily nudged themselves out of solar orbit over millions of years.

Sorting the Glow from the Flow
Published: March 02, 2020

How do you find a single cell in a sea of thousands? You make it glow. Adding fluorescence helps track movement and changes in small things like cells, DNA, and bacteria. In a library of millions of cells or bacteria, flow cytometry sorts the glowing material you want to study from the non-glowing material.

Black Holes Continue to Tear Stars Apart
Published: July 23, 2019

While we've known for a while that black holes could rip stars apart, we don’t know why these events occur so frequently. Now, a model by JILA researchers explaining this discrepancy is shown to be promising after passing its first reality test.
