JILA postdoctoral researcher Dr. Megan Bentley, a member of Heather Lewandowski’s research group, has been named a 2026 Arnold O. Beckman Postdoctoral Fellow. The prestigious national award recognizes Bentley’s innovative research and supports outstanding early‑career scientists in the chemical sciences as they transition toward independent research careers.

JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and members of her lab have shattered a 25-year-old theory about how benzene forms in the interstellar medium, revealing that the long-accepted chemical recipe doesn’t work under space-like conditions. Their groundbreaking laser-cooling experiments open a new chapter in understanding the origins of complex carbon molecules in the cosmos.

JILA and the University of Colorado Boulder are proud to announce that Professor J. Mathias Weber has been elected a Fellow of the American Physical Society (APS), for fundamental contributions to our understanding of molecular interactions and solvation effects in complex systems, obtained via elegant vibrational/electronic laser photodissociation spectroscopy of molecular and cluster ions in the gas phase.

Dr. Surya Pratap Deopa, Postdoctoral Fellow in the lab of JILA Fellow and MCDB Professor Tom Perkins, has been honored with the 2025 BioFrontiers Outstanding Contribution Award.

Understanding how molecules interact with ions is a cornerstone of chemistry, with applications from pollution detection and cleanup to drug delivery. In a series of new studies led by JILA Fellow and University of Colorado Boulder chemistry professor Mathias Weber, researchers explored how a specific ion receptor called octamethyl calix[4]pyrrole (omC4P) binds to different anions, such as fluoride or nitrate. These findings provide fundamental insights about molecular binding that could help advance fields such as environmental science and synthetic chemistry.

Dr. Olivia Krohn, a former JILA graduate student and now a postdoctoral researcher at Sandia National Laboratories, has been awarded the prestigious Justin Jankunas dissertation award, given out by the American Physical Society (APS) division of chemical physics at the APS Global Summit conference. This award recognizes exceptional doctoral research that advances the frontiers of physics. Krohn’s award highlights her dissertation research, which bridges the legacy of JILA’s origins in astrophysics with its current role as a global leader in atomic, molecular, and optical (AMO) physics.

While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at least 200 unique molecules form in its cold, low-pressure environment. It’s a subject that ties together the fields of chemistry, physics, and astronomy, as scientists from each field work to determine what types of chemical reactions happen there.

Now, in the recently published cover article of the Journal of Physical Chemistry A, JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and former JILA graduate student Olivia Krohn highlight their work to mimic ISM conditions by using Coulomb crystals, a cold pseudo-crystalline structure, to watch ions and neutral molecules interact with each other.

Every year, the Czech Science Foundation (GCAR) funds several JUNIOR STAR projects focused on new research areas and building powerful collaborative teams. These projects are awarded to early-career scientists coming to the Czech Republic from other countries or with significant international experience. Each project is awarded CZK 25 million over the following five years.
This year, JILA postdoctoral researcher Vít Svoboda is one of the 17 awardees in the 2023 JUNIOR STAR cohort.

William Carl Lineberger, 83, loving husband, died on October 17, 2023, in Boulder, Colorado. Born in 1939, in Hamlet, North Carolina, Carl was the only child of Evelyn Pilot Cooper and Caleb Henry Lineberger. He is survived by his wife, Kitty Edwards, and his beloved dog, Jude.

To better understand the dynamics of aptamer and ligand binding, Marton Menendez, along with JILA and NIST Fellow David Nesbitt, looked at the lysine (an amino acid) riboswitch in Bacillus subtilis, a common type of bacterium present in environments ranging from cow stomachs to deep sea hydrothermal vents. With this model organism, the researchers studied how different secondary ligands, like, potassium, cesium, and sodium, affect riboswitch activation, or its physical folding.
