The Diversity of Extrasolar Terrestrial Planets
, 2010 Extrasolar planetary host stars are enriched in key planet-building elements. These enrichments have the potential to drastically alter the building blocks available for terrestrial planet formation.

(Co‐)Reference All the Way Down: A Unified Theory of (Pro) Nominals in Ordinary English
Theoria, EarlyView.ABSTRACT This essay joins two themes, both arising from Kripke's inspiring ideas in the theory of reference. The first theme concerns reference in general. The second examines the notion of co‐reference and the role it plays in a unified theory of pronouns for natural language.

Methane Planets and their Mass-Radius Relation
, 2015 Knowledge of both the mass and radius of an exoplanet allows us to estimate its mean density, and therefore its composition. Exoplanets seem to fill a very large parameter space in terms of mass and composition, and unlike the solar-system's planets ...

Fugitive Junctures: Life‐Seeking, Route‐Finding and the Mobile Ensemble at Kenya's Borders
Transactions of the Institute of British Geographers, EarlyView.Short Abstract Fugitivity has become an important conceptual frame to understand the illegalised mobilities of contemporary migrants in conjunction with enslaved people's historical lines of flight as spatial praxes to seize their own freedom. Thinking from Kenya, and drawing on research with migrants, border officials, activists, police and smugglers,

Abundance, distribution, and origin of 60Fe in the solar protoplanetary disk
, 2012 Meteorites contain relict decay products of short-lived radionuclides that were present in the protoplanetary disk when asteroids and planets formed. Several studies reported a high abundance of 60Fe (t1/2=2.62+/-0.04 Myr) in chondrites (60Fe/56Fe~6*10-7)

Women in space: A review of known physiological adaptations and health perspectives
Experimental Physiology, EarlyView.Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

The Journal of Physiology, EarlyView.Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...

IR-excesses around nearby Lambda Boo stars are caused by debris disks rather than ISM bow waves
, 2015 Lambda Boo stars are predominately A-type stars with solar abundant C, N, O, and S, but up to 2 dex underabundances of refractory elements. The stars' unusual surface abundances could be due to a selective accretion of volatile gas over dust. It has been

Terrestrial Analogs to Titan for Geophysical Research
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
