A Strong Falsification of the Universal Radial Acceleration Relation in Galaxies
The Astrophysical JournalIn the past few decades, many studies revealed that there exist some apparent universal relations that can describe the dynamical properties in galaxies.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Time delay of light in the gravitational lensing of supermassive black holes in dark matter halos
European Physical Journal C: Particles and FieldsThe dark matter halo has non-negligible effects on the gravitational lensing of supermassive black hole in the galaxy center. Our work presents a study on the time-delay of light in gravitational lensing of black holes enclosed by dark matter halos.

Minor epic: Notes toward a different “Anthropoetry”
Anthropology and Humanism, Volume 51, Issue 1, June 2026.Abstract Anthropologists have often turned to poetry as a means of accessing emotional registers of which conventional academic prose is unable to avail. In doing so, they have tacitly conflated poetry with lyric poetry, today probably the most widely practiced poetic genre, associated in particular with the expression of inner feelings and subjectival

The Impact of Galaxy-halo Size Relations on Galaxy Clustering Signals
The Open Journal of AstrophysicsGalaxies come in different sizes and morphologies, and these differences are thought to correlate with properties of their underlying dark matter halos.

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.ABSTRACT Epigenetic aging models hold great promise for enhancing many aspects of wildlife research and management. However, their utility is limited by the need to train models using known‐aged animals, which are rare among wildlife species. We present a novel approach to developing methylation‐based age prediction models that enables us to train ...

From Halos to Galaxies. IX. Estimate of Halo Assembly History for SDSS Galaxy Groups
The Astrophysical JournalThe properties of the galaxies are tightly connected to their host halo mass and halo assembly history. Accurate measurement of the halo assembly history in observation is challenging but crucial to the understanding of galaxy formation and evolution ...

On the Pseudo Phase-space Density of Dark Matter Haloes and the Universality of Density Profiles
Open Astronomy, 2015 We examine the radial dependence of the pseudo phase-space density, ρ(r)/σ3(r), for structures on galactic and galaxy cluster scales. We find that it is approximately a power-law only in the range of halo radius resolved by current simulations (down to 0.

Dark-Matter Halos of Early-Type Galaxies
, 2005 Cosmological simulations of galaxy formation predict a universal form for the mass profile of dark matter (DM) halos from cluster to galaxy scales. Remarkably few interesting constraints exist, however, on DM halos in early-type galaxies. Using Chandra we present the temperature, density and mass profiles of a small sample of early-type galaxies ...

Deciphering the Transcriptomic Signatures of Aging Across Organs in Mice
Aging Cell, Volume 25, Issue 2, February 2026.Comprehensive transcriptomic profiling of eight mouse organs across six ages reveals how aging reshapes biological processes. Trajectory and network analyses distinguish shared and organ‐specific signatures, charting the molecular landscape of systemic aging.
