MiR‐21‐5p Protects Embryonic Growth and Heart Function During Developmental Hypoxia by Dampening HIF Responses and Altering Gene Expression

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
miR‐21‐5p protects embryonic growth and heart function during developmental hypoxia by dampening HIF responses and shifting gene networks toward improved cardiomyocyte survival and calcium handling. This work identifies miR‐21‐5p as a promising therapeutic target for preventing fetal growth restriction and cardiovascular impairment in high‐risk ...

Mass Distribution in Rotating Thin-Disk Galaxies According to Newtonian Dynamics

Galaxies, 2014
An accurate computational method is presented for determining the mass distribution in a mature spiral galaxy from a given rotation curve by applying Newtonian dynamics for an axisymmetrically rotating thin disk of finite size with or without a central ...

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

JOR 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.

Observational Biases on Rotation Curves from Integral Field Unit Data at Cosmic Noon

The Astrophysical Journal
Through studying rotation curves, which depict how the velocity of the stars and gas changes with distance from the center of a galaxy, it has been confirmed that dark matter dominates galaxies’ outer regions, as their rotation curve remains flat ...

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Comparison of HMG and Flat Rotation Velocities Inferred from Galaxy–Galaxy Weak Lensing

The Astrophysical Journal
Despite the success of dark matter models, unresolved issues require exploring alternatives such as modified gravity theories. In this context, we examine the compatibility of the hyperconical modified gravity (HMG) with galaxy rotation curves inferred ...

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.
