The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?
Global Policy, Volume 17, Issue 4, Page 553-565, September 2026.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.

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

Revisiting Variable Stars Toward the Globular Cluster NGC 6496 With ATLAS and Gaia Photometry
Astronomische Nachrichten, Volume 347, Issue 7, August 2026.ABSTRACT We revisit 13 variable stars in the field of the metal‐rich globular cluster NGC 6496, discovered by Abbas et al. (2015; Astronomical Journal 149:40) (hereafter referred to as “MA15”) via time‐series data, spanning 2 years. We improve upon the MA15 characterization of the variables using ATLAS time‐series photometry data, spanning 8 years, in ...

, 2018 The Milky Way Galaxy in which we live seems to be a normal spiral galaxy. But it can be hard to tell. Our perspective from within it precludes a "face-on" view like the picture above, which combines some real data with a lot of artistic liberty.

Advanced Science, Volume 13, Issue 37, 3 July 2026.Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.

Astronomische Nachrichten, Volume 347, Issue 6, July 2026.ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

Engineering Reports, Volume 8, Issue 7, July 2026.We propose the Powerful‐but‐Limited Generative AI theorem, demonstrating that embedding human‐inspired constraints, such as fixed utility functions and neuro‐symbolic submission layers, ensures generative AI remains controllable by preventing self‐improvement beyond designer intent.

Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

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