Blue-asymmetric spectral lines appear in 50-60% of dense cores within massive dark clumps, showing that gravitational collapse operates at core scales from prestellar stages onward and supports hierarchical star formation.

JWST, Subaru, and ALMA observations of HH 270 identify a new collimated jet closer to the source and show interactions between the shock-excited jet and the molecular outflow.
ALMA survey finds 4 starless cores in Orion B North consistent with turbulent collapse simulations; virial analysis indicates Chamaeleon I cores are less bound with external pressure dominating unlike Orion B North and Ophiuchus.
The paper reviews techniques for measuring protostellar accretion, analyzes methodological differences and caveats in comparing observations with simulations, and outlines next steps for a fuller picture.
