Atomistic Modeling of Methyl Formate and Glycolaldehyde Formation on Interstellar Dirty Ice Mantles via a “Radical + Ice” Mechanism

ChemPlusChem, Volume 90, Issue 11, November 10, 2025.
The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

Heavy‐element damage seeding in proteins under XFEL illumination

Journal of Synchrotron Radiation, Volume 32, Issue 5, Page 1124-1142, September 2025.
Plasma simulations with detailed modeling of unbound electron dynamics predict that heavy elements contribute significantly to radiation damage suffered by proteins in serial femtosecond crystallography. New methods to mitigate radiation damage in this regime are highlighted.Serial femtosecond X‐ray crystallography (SFX) captures the structure and ...

The sense that we're invisible: A longitudinal analysis of diverse women's experiences with structural violence in biomedical doctoral programs

Journal of Research in Science Teaching, Volume 62, Issue 6, Page 1492-1521, August 2025.
Abstract A longstanding and significant disparity in representation across gender, economic status, ethnicity, race, and sexual identity exists within STEM doctoral training. Most of the research on the retention and attrition of minoritized PhD STEM students focuses on individual factors, rather than system level issues.
