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 ...

VLA FRAMEx. I. Wideband Radio Properties of the AGN in NGC 4388

The Astrophysical Journal
We present the first results from Karl G. Jansky Very Large Array (VLA) observations as a part of the Fundamental Reference Active Galactic Nucleus (AGN) Monitoring Experiment, a program to understand the relationship between AGN accretion physics and ...

Advancing Deuterium MRI to Track Human Cerebral Glucose Metabolism at 7 T: A Comparison of Glucose‐d2 and Glucose‐d7 Ingestion

NMR in Biomedicine, Volume 38, Issue 12, December 2025.
Deuterium metabolic imaging (DMI) enables non‐invasive assessment of glucose metabolism in the human brain. This study compared the use of glucose‐d7 ([1,2,3,4,5,6,6’‐2H7]glucose) and glucose‐d2 ([6,6’‐2H2]glucose) as an ingested tracer in 15 healthy participants at 7 T.

A 3.5mm Polarimetric Survey of Radio-loud Active Galactic Nuclei

, 2010
We present the results from the first large (>100 source) 3.5 mm polarimetric survey of radio loud active galactic nuclei (AGN). The I, Q, U, and V Stokes parameter observations were performed with the XPOL polarimeter at the IRAM 30m Telescope.

On the Jet Properties of γ-Ray-loud Active Galactic Nuclei [PDF]

, 2018
Based on broadband spectral energy distributions (SEDs), we estimate the jet physical parameters of 1392 γ-ray-loud active galactic nuclei (AGNs), the largest sample so far. The (SED) jet power and magnetization parameter are derived for these AGNs.

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

Advanced Functional Materials, Volume 35, Issue 46, November 12, 2025.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

An Excess of Active Galactic Nuclei Triggered by Galaxy Mergers in MaNGA Galaxies of Stellar Mass ∼1011 M ⊙

The Astrophysical Journal
To facilitate new studies of galaxy-merger-driven fueling of active galactic nuclei (AGNs), we present a catalog of 387 AGNs that we have identified in the final population of over 10,000 z < 0.15 galaxies observed by the Sloan Digital Sky Survey-IV ...

Infrared Photovoltaic–Battery Hybrid Systems Enabled by Colloidal Quantum Dots

Chemistry – An Asian Journal, Volume 20, Issue 21, November 3, 2025.
Photovoltaic–battery (PV/B) hybrid systems are key for sustainable energy but face cost and efficiency limits. Colloidal quantum dots (CQDs) enable low‐cost near‐infrared light harvesting, surpassing silicon and III–V PVs. This review analyzes CQD properties, their roles in NIR PVs and batteries, and synthesizes current research to highlight progress ...

Panic at the ISCO: Time-varying Double-peaked Broad Lines from Evolving Accretion Disks Are Common among Optically Variable AGNs

The Astrophysical Journal
About 3%–10% of Type I active galactic nuclei (AGNs) have double-peaked broad Balmer lines in their optical spectra originating from the motion of gas in their accretion disk.
