Direct Measurement of Polar Coronal Hole-like Solar Wind in Its Acceleration Phase

Abstract The early evolution of fast polar coronal hole (PCH) solar wind remains largely unconstrained by in situ measurements. In 2025 March, Parker Solar Probe (Parker) at its closest approach of 9.86 solar radii ( R ⊙ ) measured outflow from a large equatorial coronal hole (EC...

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

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 i...
