Chemical Evolution of Bulges of Active Galactic Nuclei in the Early Universe: Roles of Accreting Stars

The Astrophysical Journal
JWST/NIRCam observations reveal dense stellar cores in high-redshift galactic bulges, indicative of sustained star formation and potential stellar accretion.

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 351-370, March 2026.
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

A 13 Billion Year View of Galaxy Growth: Metallicity Gradient Evolution from the Local Universe to z = 9 with JWST and Archival Surveys

The Astrophysical Journal Supplement Series
Galaxy gas-phase metallicity gradients have been extensively studied over the past four decades, both in the local and in the high-redshift Universe, as they trace the baryon cycle and growth of galaxies.

A Proof‐of‐Concept Study of Gamified Rhythmic Training in Preadolescents Who Stutter

Annals of the New York Academy of Sciences, Volume 1557, Issue 1, March 2026.
This proof‐of‐concept study tested a gamified rhythmic‐training app, Rhythm Workers, in preadolescents who stutter. Over three weeks, participants trained at home and were compared to an active control game. The rhythm group showed dose‐dependent improvements in rhythmic synchronization, interference control, oromotor accuracy, and speech fluency ...

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.

On the Significance of the Thick Disks of Disk Galaxies

The Astrophysical Journal Supplement Series
Thick disks are a prevalent feature observed in numerous disk galaxies, including our own Milky Way. Their significance has been reported to vary widely, ranging from a few percent to 100% of the disk mass, depending on the galaxy and the measurement ...

Atmospheric and Deposition Responses of 10Be to Volcanic Eruptions Inferred From the Aerosol‐Climate Model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract 10Be deposition in ice cores is widely used for solar reconstructions, but its interpretation is complicated by volcanic influences. Using the state‐of‐the‐art aerosol‐climate model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be, we assess the impacts of three major volcanic eruptions: Agung (1963), El Chichón (1982) and Pinatubo (1991). All eruptions enhance
