Blackbody Quasar and Radio Source (BBQSORS): A Candidate of Transitional Little Red Dots with a T ∼ 104 K Blackbody Spectrum

open access: yesThe Astrophysical Journal Letters
JWST surveys have identified a new class of active galactic nuclei (AGNs) called little red dots (LRDs). Their observational properties challenge the canonical AGN paradigm and provide key insights into the early growth phase of the supermassive black ...

Survey on Visualization of Information Diffusion over Networks

open access: yesComputer Graphics Forum, EarlyView.
Abstract Information Diffusion (ID) describes how a value (e.g., a pathogen, a rumor, a packet) spreads through an underlying “medium” network of elements (e.g., a social or computer network). Understanding the information diffusion process is essential to predicting trends, controlling misinformation, and enhancing decision‐making as well as ...

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

open access: yesPlant, Cell &Environment, EarlyView.
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 ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental 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 ...

Proton‐Radiation Hardening of High‐Speed Ge/Si Integrated Photodetectors for Space Applications

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Hydrogen loading is demonstrated as a radiation‐hardening strategy for high‐speed Ge/Si integrated photodetectors under broadband proton irradiation. By suppressing irradiation‐induced leakage‐current growth and mitigating bandwidth degradation, hydrogen‐loaded devices maintain high‐speed operation and improved stability, providing a practical route ...

A Constellation of Fluorescent Biosensors to Illuminate the Galaxy of Protein Kinases

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Protein kinases (PKs) are enzymes that catalyze phosphorylation of protein substrates involved in a wide variety of biological signalling pathways. This review describes the different families and mechanisms of action and regulation of protein kinases, together with the different classes of fluorescent biosensors that have been engineered and ...

Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei

open access: yesAstronomische Nachrichten, Volume 347, Issue 5, June 2026.
ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

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

open access: yesRadio 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.

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

open access: yesJournal 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.
