Archives of impact: The politics of craters on Earth
Geographical Research, Volume 64, Issue 2, May 2026.This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Detection of Multiple Phase Space Overdensities of GSE Stars by Orbit Integration
The Astrophysical Journal, 2023 In N -body simulations, nearly radial mergers can form shell-like overdensities in the sky position and phase space ( r − v _r ) due to the combination of dynamical friction and tidal stripping.

The Milky Way Galaxy as a strong gravitational lens [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 We study the gravitational lensing effects of spiral galaxies by taking a model of the Milky Way and computing its lensing properties. The model is composed of a spherical Hernquist bulge, a Miyamoto-Nagai disc and an isothermal halo. As a strong lens, a spiral galaxy like the Milky Way can give rise to four different imaging geometries.

Aging Cell, Volume 25, Issue 5, May 2026.Environmentally relevant enrofloxacin accelerates intestinal aging by impairing epithelial mitochondrial function, disrupting barrier integrity, and reshaping the gut microbiota. Mitochondrial restoration with pyrroloquinoline quinone alleviates hypoxia, inflammation, and gut damage.

Generalized Rotation Curves of the Milky Way from the GAIA DR3 Data Set: Constraints on Mass Models
The Astrophysical JournalThe circular velocity curve traced by stars provides a direct means of investigating the potential and mass distribution of the Milky Way. Recent measurements of the Galaxy’s rotation curve have revealed a significant decrease in velocity for Galactic ...

Tracing out the Northern Tidal Stream of the Sagittarius Dwarf Spheoridal Galaxy
, 2003 The main aim of this paper is to report two new detections of tidal debris in the northern stream of the Sagittarius dwarf galaxy located at 45 arcdeg and 55 arcdeg from the center of galaxy.

Molecular Nutrition &Food Research, Volume 70, Issue 7, 15 April 2026.Obesity caused by a high‐fat diet (HFD) is known to result from interactions between the gut microbiota, intestinal barrier function, and excessive inflammatory responses in the colon. In this study, we found that dietary intake of whole blackcurrants prevented HFD‐induced obesity by restoring gut microbiota dysbiosis, upregulating intestinal barrier ...

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Watching Our Galaxy Grow Up: The Mass and Color Evolution of the Milky Way
The Astrophysical JournalUsing our rich observations within the Milky Way to better understand galaxy evolution requires understanding what the Milky Way looks like “as a galaxy”—that is, its “true” shape and abundance profiles (unskewed by observational biases), signatures of ...
