Sociology and The Complexity of What Is Missing
The British Journal of Sociology, Volume 77, Issue 2, Page 332-344, March 2026.ABSTRACT What is ‘missed’ by sociological literature underpinned by assumptions of presence that a missing approach can rectify? I appropriate a metaphysics of presence and an alternative focus on what is missing as ontological foci to revisit complexity studies in sociology.

, 2015 The diffuse extended outer regions of galaxies are hard to study because they are faint, with typical surface brightness of 1% of the dark night sky. We can tackle this problem by using resolved star tracers which remain visible at large distances from ...

Affective Infrastructure: Capitalism's Specters in the Ecovillage Findhorn Community
Anthropology of Consciousness, Volume 37, Issue 1, Spring 2026.ABSTRACT The Ecovillage Findhorn Community (EFC) in Northeast Scotland seeks to live in harmony with nature. How the community has done this over its 60‐plus years has changed from social communalism, where residents lived in cheap caravans, to now mostly privately‐owned expensive ‘eco’ houses with green technology.

Apatite in Bennu samples indicates multiple stages of aqueous alteration
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 504-521, March 2026.Abstract Calcium phosphates are ubiquitous in planetary materials, including samples returned from asteroid Bennu by the OSIRIS‐REx mission. We characterized apatite [Ca5(PO4)3(F,Cl,OH)] grains in Bennu samples by scanning electron microscopy, electron microprobe analysis, and transmission electron microscopy to investigate their compositions, mineral ...

Planetary nebulae after common-envelope phases initiated by low-mass red giants
, 2013 It is likely that at least some planetary nebulae are composed of matter which was ejected from a binary star system during common-envelope (CE) evolution.

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract Primitive asteroids and carbonaceous chondrites (CCs) record the history of processes in the early solar system. Visible and shortwave infrared (VSWIR) spectroscopy of primitive asteroids and bulk‐powdered CCs has identified shared spectral features suggestive of shared parent body origins.

Characteristics of Natural Remanence Records in Fine‐Grained Particles Returned From Asteroid Ryugu
Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract Particles collected from the asteroid Ryugu by the Hayabusa2 spacecraft offer a unique opportunity to investigate the magnetic record of the primitive solar system, as any terrestrial magnetic contamination is minimal and can be accounted for.
