Microbial D/H fractionation in extraterrestrial materials: application to micrometeorites and Mars [PDF]
, 2004 High D/H terrestrial alteration of micrometeorites is described and suggested to be a result of microbial isotopic fractionation by methanogens.

The Mission (Im)possible of Climate Action through Quixotic Institutional Work
Journal of Management Studies, EarlyView.Abstract The ‘iron cage’ of the (neo‐) liberal‐capitalist system prioritizes economic returns over climate protection. Formerly powerful nation‐states are subordinated to the rule of markets, whereas business elites have been freed from substantial responsibility for social and environmental concerns.

Mining cosmic dust from the blue ice lakes of Greenland [PDF]
Extraterrestrial material, most of which invisible settles to Earth's surface as dust particles smaller than a millimeter in size were investigated. Particles of 1/10 millimeter size fall at a rate of one/sq m/yr collection of extraterrestrial dust is ...

Astrobiological Effects of F, G, K and M Main-Sequence Stars
, 2008 We focus on the astrobiological effects of photospheric radiation produced by main-sequence stars of spectral types F, G, K, and M. The photospheric radiation is represented by using realistic spectra, taking into account millions or hundred of millions ...

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 506-528, March 2025.Abstract JAXA's Hayabusa2 sample return mission visited the volatile‐rich carbonaceous (C‐type) asteroid (162173) Ryugu with the aim of ground‐truthing remote observations, returning a pristine sample from a C‐type asteroid, and strengthening links between asteroids and the meteorite collection. Here, we have conducted a systematic study of coarse (>10

SET-E: The Search for Extraterrestrial Environmentalism [PDF]
, 2016 There is currently no evidence for life on any known exoplanet. Here, we propose a form of "galactic anthropology" to detect not only the existence of life on transiting exoplanets, but also the existence of environmentalism movements.
