Radio continuum evidence for nuclear outflow in the Circinus galaxy [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
Australia Telescope Compact Array radio continuum maps of the edge-on galaxy in Circinus are presented for four frequencies. The unresolved core of the galaxy measures less than 20 pc in diameter and has a flat spectral index of a = -0.06 ± 0.15 (S ∝ v).

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

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 ...

Mapping Immunity With Cutting‐Edge Spatial Biology and Tissue Cytometry Innovations

MedComm, Volume 7, Issue 6, June 2026.
This review explores how spatial biology integrates multiplexed imaging and tissue cytometry to reveal immune organization within native tissue contexts. ABSTRACT The immune system operates within organized tissue landscapes, where spatial relationships between cells shape the nature and outcome of immune responses.

Solar Energetic Particle Prediction in the Inner Heliosphere Using Deep Learning and PSP/IS⊙IS Data

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Solar events, such as coronal mass ejections and solar flares, accelerate large numbers of energetic charged particles, producing solar energetic particle (SEP) events that can harm astronauts, damage satellites, and potentially damage infrastructure on Earth.

Controlling 3D Contractility via Engineered Fibrous Hydrogel Composites

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
A tunable composite contractile assembly (CCA) is developed that can permit or resist contraction without changing cell‐adhesion and density, unlike collagen whose inherent coupling of these ECM cues limits its use as a platform in contractility studies.
