The SVP–FRO6 Module Integrates the Control of Leaf Senescence and Flowering in Arabidopsis

open access: yesPlant, Cell &Environment, Volume 49, Issue 9, Page 7191-7209, September 2026.
ABSTRACT Plants coordinate major developmental transitions by integrating intrinsic genetic programs with environmental signals, where nutrient availability serves as a critical external factor shaping growth and fitness. Iron (Fe), an essential micronutrient for cellular respiration and photosynthesis, is strictly regulated through sophisticated ...

When Communication Enables Catastrophe: Nuclear Risk and the Short Lifetimes of Technological Civilizations

open access: yesRisk Analysis, Volume 46, Issue 9, September 2026.
ABSTRACT The Fermi paradox may partly reflect technological self‐destruction acting as a Great Filter during post‐industrial development. Because the empirical record consists of a single civilization observed over an eighty‐year nuclear age, the exercise reported here is best understood as a structured, historically anchored scenario analysis rather ...

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

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 4235-4247, 1 September 2026.
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

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
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 ...

Radio Continuum Maps of Southern Barred Spiral Galaxies [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
AbstractA sample of southern spiral galaxies are being observed at 20 and 13 cm with the Australia Telescope Compact Array in order to look for examples of anomalous outflows from the nuclear region. In this paper we discuss the radio continuum maps of the three barred spiral galaxies observed to date.

Solvent‐Guided Chiral Assemblies and Chemical Doping of OEG‐Functionalized Conjugated Polymers

open access: yesAdvanced Materials, Volume 38, Issue 45, 13 August 2026.
Solvent‐dependent aggregation pathways dictate whether conjugated polymers form chiral lyotropic liquid‐crystalline assemblies or achiral packed aggregates. Mapping solvent‐controlled β₁ and β2 states reveals that weaker backbone association favors β₁ aggregates and reorganizable twisted mesophases, whereas stronger backbone association favors β2 ...

Photoresponsive MoS2‐Based Artificial Synaptic Transistor for Wavelength‐Dependent Physical Reservoir Computing

open access: yesSmall Structures, Volume 7, Issue 8, August 2026.
The illumination wavelength sets the relaxation timescale of persistent photoconductivity in a back‐gated MoS2 photonic synapse. Red, green, and blue light supply three distinct fading‐memory channels within a single device. Combining these spectral channels into one reservoir achieves best performance of a nonlinear time‐series prediction below that ...

Statistical Survey of Cosmic Noise Absorption in Conjunction With Plasma Wave Measurements

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using a decade of observations from the Canadian Geospace Observatory Riometer Network (GO‐RIO), we selected an east‐west subset of stations near L∼7 $L\sim 7$ to classify cosmic noise absorption (CNA) (a proxy for enhanced D‐region ionization) into two morphologies, simultaneous and drifting, based on the relative timing of signals across the

Radio-continuum emission from quasar host galaxies

open access: yesThe Astronomical Journal, 1987
Seven low-redshift quasars that are likely to be in spiral galaxies have been observed in a search for radio-continuum emission from the host galaxies of quasars. The properties of the individual quasars are listed, and 1.49 GHz contour maps of the seven quasar fields are presented.
