Deletion of a Pax1 Sex‐Associated Genomic Region Associated With Adolescent Idiopathic Scoliosis Leads to Disc Degeneration, Instability, and Vertebral Rotation in Mice

open access: yesJOR SPINE, Volume 9, Issue 2, June 2026.
Overview of the effects of Pax1‐SAR deletion on gene expression, IVD degeneration, and resultant scoliotic‐like curvature between sexes. Proposed mechanism of sex‐dependent changes in gene expression in females (right) and males (left), resulting in sex‐dependent disc degeneration and scoliotic phenotypes.

Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.

A Possible Solution to the Mystery of the ANITA Anomalous Events

open access: yesAnnalen der Physik, Volume 538, Issue 4, April 2026.
In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte 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.

Cosmic-Ray Nuclei, Antiprotons and Gamma-rays in the Galaxy: a New Diffusion Model [PDF]

open access: yes, 2015
We model the transport of cosmic ray nuclei in the Galaxy by means of a new numerical code. Differently from previous numerical models we account for a generic spatial distribution of the diffusion coefficient.

A Modified 3D Biconical Outflow Model: Spatial Constraints on Active Galactic Nuclei–Driven Outflows

open access: yesThe Astrophysical Journal
We present a modified outflow model and its application to constrain ionized outflow properties of active galactic nuclei (AGNs). By adding a rotating disk component to the biconical outflow model of H.-J. Bae & J.-H.

VLBI Observations of NGC6240: resolving the double nuclei and radio supernovae

open access: yes, 2011
The European VLBI Network (EVN) has been used at two epochs in 2003 and 2009 to obtain multi-frequency high-resolution images of the merger galaxy NGC6240 in order to study the radio properties of all compact high-brightness components in the galaxy. Our

Influence of Mars Topography on Radiation Dose Detected by the Mars Science Laboratory and Assessment of Mars Surface Albedo Radiation

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The Radiation Assessment Detector (RAD) on the Curiosity rover has been characterizing the Martian surface radiation field since 2012. The dose observed by RAD is influenced by a variety of factors, including an essential one, the terrain. After parking near Murray Buttes in September 2016 where it first detected a ∼5% decrease in dose rate ...

The ACS Fornax Cluster Survey. VI. The Nuclei of Early-Type Galaxies in the Fornax Cluster

open access: yes, 2012
The Advanced Camera for Surveys (ACS) Fornax Cluster Survey is a Hubble Space Telescope program to image 43 early-type galaxies in the Fornax cluster, using the F475W and F850LP bandpasses of the ACS.

The census of nuclear activity of late-type galaxies in the Virgo cluster [PDF]

open access: yes, 2007
The first spectroscopic census of AGNs associated to late-type galaxies in the Virgo cluster is carried on by observing 213 out of a complete set of 237 galaxies more massive than M_dyn>10^{8.5} solar masses.
