TiNy Titans H I: Discovering Satellites via H I Gas in an Isolated, Compact Group of Dwarf Galaxies

The Astrophysical Journal
We report on the H I content of an isolated, compact group of six dwarf galaxies at a distance of 145 Mpc. The distribution and kinematics of the H ​​​​​​ I , including multiple gaseous bridges, indicate the group is a gravitationally bound system. The H

Caxton's Afterlife in Manuscript (c.1475‐c.1500)

Renaissance Studies, EarlyView.
Abstract At least thirty‐five manuscript copies of Caxton's prints have been found so far. This article explores the implications of such manuscript copies of Caxton's prints and, interrupting the linear history of the book, considers Caxton's appeal beyond print in manuscript.

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

Transactions of the Institute of British Geographers, EarlyView.
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 ...

Improving the Determination of Supernova Cosmological Redshifts by Using Galaxy Groups

The Astrophysical Journal
At the low-redshift end ( z < 0.05) of the Hubble diagram with Type Ia Supernovae (SNe Ia), the contribution to Hubble residual scatter from peculiar velocities (PVs) is of similar size to that due to the limitations of the standardization of the SN Ia ...

Technical considerations and review of urinary microRNAs as biomarkers for chronic kidney disease in dogs and cats

Veterinary Clinical Pathology, EarlyView.
Abstract MicroRNAs (miRNAs or miRs) are small, non‐coding RNAs that play a crucial role in gene regulation, making them potential biomarkers for various diseases. In the field of veterinary medicine, there is a growing interest in exploring the diagnostic and therapeutic potential of miRNAs in kidney diseases affecting dogs and cats.

Unveiling the Sources of X-Ray Luminosity in DESI Galaxy Groups: Insights from the SRG/eROSITA All-sky Survey

The Astrophysical Journal
We use the first eROSITA all-sky survey to investigate the contributions of active galactic nuclei (AGN) and extended gas to the total X-ray luminosity ( L _X ) of galaxy groups with different halo masses ( M _h ) at different redshifts.

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

Experimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...
