The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?
Global Policy, EarlyView.ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

The Story(line) So Far: A Survey on Storyline Visualization
Computer Graphics Forum, EarlyView.Abstract Storyline visualizations model narratives as temporal networks, using x‐monotone lines to represent entities and their interactions over time. This technique offers an intuitive way to reveal structural patterns over time, such as character co‐occurrence and narrative flow.

The futuristic manifolds of REM sleep
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Since one of its first descriptions 70 years ago, rapid eye movement sleep has continually inspired and excited new generations of sleep researchers. Despite significant advancements in understanding its neurocircuitry, underlying mechanisms and microstates, many questions regarding its function, especially beyond the early neurodevelopment ...

Measurement of Interstellar Magnetization by Synchrotron Polarization Variance
The Astrophysical JournalSince synchrotron polarization fluctuations are related to the fundamental properties of the magnetic field, we propose the polarization intensity variance to measure the Galactic interstellar medium (ISM) magnetization.

Turbulence in the molecular interstellar medium [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractThe observational record of turbulence within the molecular gas phase of the interstellar medium is summarized. We briefly review the analysis methods used to recover the velocity structure function from spectroscopic imaging and the application of these tools on sets of cloud data.

Renaissance Studies, EarlyView.ABSTRACT This article examines the iconography of the Andromeda constellation as an intersex figure within medieval and early modern astrological traditions. It focuses on the origins of this imagery in the thirteenth‐century astrological writings of Scot and its reappearance nearly three centuries later in Ratdolt's illustrated 1482 edition of Hyginus'

CF+ excitation in the interstellar medium
Astronomy & Astrophysics, 2020 The detection of CF+ in interstellar clouds potentially allows astronomers to infer the elemental fluorine abundance and the ionization fraction in ultraviolet-illuminated molecular gas. Because local thermodynamic equilibrium (LTE) conditions are hardly fulfilled in the interstellar medium (ISM), the accurate determination of the CF+ abundance ...

Deuterium enrichment of the interstellar medium [PDF]
New Astronomy, 2015 Despite low elemental abundance of atomic deuterium in interstellar medium (ISM), observational evidences suggest that several species in gas-phase and in ices could be heavily fractionated. We explore various aspects of deuterium enrichment by constructing a chemical evolution model in gas and grain phases.

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 ...

Studying Magnetic Reconnection with Synchrotron Polarization Statistics
The Astrophysical JournalMagnetic reconnection is a fundamental process for releasing magnetic energy in space physics and astrophysics. At present, the usual way to investigate the reconnection process is through analytical studies or first-principle numerical simulations. This
