Sorting the Glow from the Flow
Published:

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:

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.

Optical tweezers achieve new feats of capturing atoms
Published:

Trapping single atoms is a bit like herding cats, which makes researchers at the University of Colorado Boulder expert feline wranglers. In a new study, a team led by physicist Cindy Regal showed that it could load groups of individual atoms into large grids with an efficiency unmatched by existing methods.

The Snowflake of Insulators
Published:

By using ultrafast lasers to measure the temperature of electrons, JILA researchers have discovered a never-before-seen state in an otherwise standard semiconductor. This research is the most recent demonstration of a new technique, called ultrafast electron calorimetry, which uses light to manipulate well-known materials in new ways.
