The Chemical Inheritance of Icy Moons

AbstractLarge icy exomoons may represent a ubiquitous habitable environment yet remain on the fringes of detectability.   Despite decades of progress in theoretical work, the nature and origin of the solids which form the building blocks of  satellites remains a topic of debate. We utilize a radiation-thermochemical disk modeling code

DNA barcoding of more than one million insect specimens indicates that at least one third of California's insect biodiversity remains undiscovered

Ecography, EarlyView.
Insects are the most diverse terrestrial organisms, yet they are underrepresented in large‐scale conservation assessments. To address this gap, the California Insect Barcoding Initiative is developing a publicly accessible, statewide DNA‐barcode reference library for California insects to support scalable surveys, establish baseline biodiversity ...

The new meaning of retirement for bridge employees: Situating bridge employment through the lens of the Kaleidoscope Career Model

Human Resource Development Quarterly, Volume 36, Issue 1, Page 89-112, Spring 2025.
Abstract Retirees re‐entering the workforce, popularly termed as bridge employment, is a phenomenon that is anticipated to increase in the coming years. Though research establishes that these employees have unique aspirations and work motives (see Mazumdar et al., 2020), primary research on how the retirement transition and bridge employment shape each
