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.

The Search for Very High Energy γ-rays from Misaligned AGN [PDF]
, 2013 The aim of this work is to study the potential for emission at very high energies (100 GeV) by misaligned active galactic nuclei (AGN) and the future prospects for observations of these objects with the next generation imaging atmospheric Cherenkov ...

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

Risk 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 ...

Radio-Excess IRAS Galaxies: Low Power CSS/GPS sources?
, 2015 Amongst our sample of radio-excess IRAS galaxies, we have identified compact steep spectrum radio sources that fall into the classes of CSS or GPS sources, but have not previously been identified as such.

Experimental 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.

, 2006 We are investigating possible triggering scenarios which may give rise to powerful jetted active galaxies such as classical double radio galaxies. Important clues come from studying those objects which have most recently been triggered. The newly discovered 'Youth-Redshift Degeneracy' for classical double radio galaxies means that the highest redshift ...

The clustering and X-ray properties of faint galaxies [PDF]
, 1994 The clustering properties of faint (23 ≤ B ≤ 27) galaxies were investigated, with the aim of obtaining information about their redshift distribution, N(z), and therefore about the processes of galaxy evolution causing the steep rise in the galaxy number ...
