Magnetic Evolution of Super‐Earth Exoplanets With a Basal Magma Ocean
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Habitability of super‐Earths likely requires self‐sustained magnetic fields to shield their atmospheres from stellar forcing. Extreme pressures and temperatures probably produce a long‐lived basal magma ocean (BMO), a potential source for these fields.

The Astrophysical JournalIn this paper, an oversimplified model is proposed to test the effects of intrinsic active galactic nucleus (AGN) variability on expected optical quasiperiodic oscillations (QPOs) related to subparsec binary black hole systems (BBHs) in broad-line AGN ...

Active Galactic Nucleus Activity in Giant, Low Surface Brightness Galaxies
The Astronomical Journal, 1998 A search of large, H I–rich disk galaxies finds a significantly higher fraction of low-luminosity active galactic nucleus (AGN) signatures compared with other late-type galaxies. Approximately half the galaxies selected in this sample have AGN-like behavior in their cores; the rest have H II nuclei resulting from simple star formation.

The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements
Space Weather, Volume 24, Issue 3, March 2026.Abstract Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs), resulting in significantly higher radiation levels and enhanced health risks. Understanding

Nucleolar dominance arises in Spartina homoploid hybrids and persists after allopolyploidization
The Plant Journal, Volume 125, Issue 5, March 2026.Significance Statement Evolution of nucleolar dominance in Spartina anglica since its origin c. 150 years ago. mC, cytosine methylation; NOR, nucleolar organizer regions. rDNA resides within the NORs. Spartina anglica C.E. Hubbard presents an iconic allopolyploid species that formed only 150 years ago, spreading worldwide since then.
