Random Mutagenesis in Porphyromonas gingivalis Enables Isolation of Mutants With Enhanced Secreted Protease Activity

Molecular Oral Microbiology, Volume 41, Issue 3, Page 158-164, June 2026.
ABSTRACT Porphyromonas gingivalis is a key pathogen in periodontitis, with secreted proteases as major virulence factors. We developed a screening method to generate and identify P. gingivalis mutants with elevated protease activity. Mutations were induced using the mutagens 2,6‐diaminopurine (2,6‐DAP) or ethyl methanesulfonate (EMS), and the ...

Computers in Our Cosmos: Intersections in Geographies of Care, Abolition Geographies and Worker Movements

Transactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
ABSTRACT AI assistants on spacecrafts. Netflix streamed through inter‐planetary communication networks. Colonies on Mars by 2050. While the glamorous public–private ventures into outer space curate discussions on the technical specificities of these proposed projects, this paper reorients discussions on such developments through critical frameworks of ...

Terrestrial Runoff Divides the Central Arctic Ocean and Shapes the Biologically Relevant Marine Lightscape

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Arctic Ocean is undergoing drastic changes in its sea ice cover, but is also optically complex. Observations from summer 2022 across the western Eurasian Basin, show increased colored dissolved organic matter (CDOM) absorption from terrestrial‐derived runoff within the Transpolar Drift (TPD) in the Amundsen Basin, extending down to a depth

Large‐Scale Magnetosheath Jets Formed by Shock‐Discontinuity Interactions: A Three‐Dimensional Global Hybrid Simulation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Magnetosheath high‐speed jets with enhanced dynamic pressure are common in Earth's magnetosheath and can impinge on the magnetopause, driving pronounced boundary deformation. Recent observations indicate that shock–discontinuity interactions (SDIs) can generate magnetosheath jets, but the formation mechanism is still unclear.

Apollo 17 Lunar Surface Gravimeter as a Seismometer: Relocating Shallow‐Moonquake Sources and Implications for Source Mechanism

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Among the reported seismic events on the Moon, shallow moonquakes are known for their unique features, such as high‐frequency energy excitation, similarity to intraplate earthquakes, and the largest energy release of all reported moonquakes. Despite these interesting features, a small number of samples (<80 events) and sparse seismic network ...
