An Ionic Limit to Life in the Deep Subsurface

Frontiers in Microbiology, 2019
The physical and chemical factors that can limit or prevent microbial growth in the deep subsurface are not well defined. Brines from an evaporite sequence were sampled in the Boulby Mine, United Kingdom between 800 and 1300 m depth.

The Influence of Tidal Heating on the Habitability of Planets Orbiting White Dwarfs

The Astrophysical Journal Letters, 2023
In recent years, there have been a growing number of observations indicating the presence of rocky material in short-period orbits around white dwarfs. In this Letter, we revisit the prospects for habitability around these post-main-sequence star systems.

Prospects for the characterization of habitable planets

Comptes Rendus. Physique, 2023
With thousands of exoplanets now identified, the characterization of habitable planets and the potential identification of inhabited ones is a major challenge for the coming decades.

A target list for searching for habitable exomoons [PDF]

, 2022
We investigate the habitability of hypothethical moons orbiting known exoplanets. This study focuses on big, rocky exomoons that are capable of maintaining a significant atmosphere. To determine their habitability, we calculate the incident stellar radiation and the tidal heating flux arising in the moons as the two main contributors to the energy ...

Capital, change and Elsie's Place: Understanding the history of safe accommodation in Australia

Public Health Nursing, Volume 40, Issue 1, Page 191-194, January/February 2023., 2023
Abstract Gendered violence, specifically, domestic violence, continues to be a global issue impacting the health and well‐being of women despite the improvements to women's rights and the expansion of women's health and well‐being services in the 1970s.

A Soft‐Soft Contact Triboelectric Nanogenerator with a Ternary Four‐Phase Structure for Self‐Powered High‐Efficiency Dust Removal on Mars

Advanced Science, EarlyView.
The frequent dust storms and charged dust particles on Mars pose significant challenges to the power generation efficiency and service life of solar panels during exploration missions. This paper proposes a novel wind‐driven ternary four‐phase soft‐soft contact triboelectric nanogenerator (FPS‐TENG) for dust removal.

Degassing of CO2 triggers large-scale loss of helium from magma oceans

Communications Earth & Environment
The moon-forming impact caused widespread melting and vaporization of the proto-Earth, leading to the formation of a protolunar disk1,2. Volatile elements trapped in the inner parts of the disk condensed together with heavier elements into a global magma

Evolution of galaxy habitability [PDF]

A&A 592, A96 (2016), 2016
We combine a semi-analytic model of galaxy evolution with constraints on circumstellar habitable zones and the distribution of terrestrial planets to probe the suitability of galaxies of different mass and type to host habitable planets, and how it evolves with time.

Horizon scanning of potential invasive alien plant species and their distribution in Norway under a changing climate

Ecography, EarlyView.
Invasive alien plant species can cause considerable ecological, economic, and social impacts, and the number of impactful species will likely increase with globalisation and anthropogenic climate change. Preventing potentially invasive alien plant species from becoming introduced is the most cost‐effective way to protect Norway's ecosystems from future

Information needs, approaches, and case studies in human health risk communication

Risk Analysis, Volume 42, Issue 11, Page 2376-2399, November 2022., 2022
Abstract This article uses ten case studies to illustrate the information needs, various communication approaches, and the communicator's role in explaining environmental health risks from a variety of hazards, to a variety of audiences, over time frames from days to years, using in person consultation, lectures, zooms, and email formats.
