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 ...

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

Sun-as-a-star Analysis of the Solar Eruption Source Region Using Hα Spectroscopic Observations of CHASE

The Astrophysical Journal
Sun-as-a-star analyses serve as a bridge for comparative studies on solar and stellar activities. To investigate the typical Sun-as-a-star H α temporal spectral characteristics in solar eruption source regions, we analyzed five different types of solar ...

Observations of an extreme storm in interplanetary space caused by successive coronal mass ejections

, 2014
Space weather refers to dynamic conditions on the Sun and in the space environment of the Earth, which are often driven by solar eruptions and their subsequent interplanetary disturbances.

Plasmoid-Induced-Reconnection and Fractal Reconnection [PDF]

, 2000
As a key to undertanding the basic mechanism for fast reconnection in solar flares, plasmoid-induced-reconnection and fractal reconnection are proposed and examined.

Validation of Intravoxel Incoherent Motion MRI Using Perfused Explanted Human Livers

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2291-2304, April 2026.
ABSTRACT Purpose Evaluate the feasibility of using perfused explanted human livers for validating intravoxel incoherent motion (IVIM). Methods Eight (n = 8) explanted livers from deceased donors were obtained. The portal vein and hepatic artery of each explanted liver were connected to a perfusion system.

When Magnetic Field Lines Stretch, Snap, and Expand: A New Look at Solar Flares with L-maps

The Astrophysical Journal
Understanding the three-dimensional evolution of coronal magnetic fields during solar flares remains challenging due to the lack of direct coronal field measurements.

Magnetic Structure of Rapidly Rotating FK Comae-Type Coronae

, 2010
We present a three-dimensional simulation of the corona of an FK Com-type rapidly rotating G giant using a magnetohydrodynamic model that was originally developed for the solar corona in order to capture the more realistic, non-potential coronal ...

ULF Wave Modulation of Energetic Electron Precipitation Caused by the Self‐Limiting of Space Radiation: May 2024 Superstorm Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The May 2024 geomagnetic superstorm provided the opportunity to explore how strong wave‐particle interactions affect energetic electron precipitation under intense driving. Using coordinated measurements from a balloon‐borne Timepix‐based X‐ray detector, ground‐based riometers and magnetometers, and Arase satellite observations, we identified ...

Why Coronal Mass Ejections Arrive Differently: Solar Cycle Modulation Through Solar Wind Structure

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Coronal Mass Ejections (CMEs) are large structures of magnetized plasma ejected from the Sun's atmosphere into the heliosphere. The interaction of CMEs with the ambient solar wind during propagation affects arrival time and speed at Earth. Since the solar wind structure changes with the solar cycle, variability in the transit times and arrival
