Reactivity of Cyanide at Water-Ice Interfaces: Implications for the Search for Organics on Icy Worlds

open access: yesFrontiers in Astronomy and Space Sciences, 2020
Icy moons in our solar system are targets of interest to search for signs of life and habitability beyond Earth. They are the astrobiological aim for several developing space missions (JUICE, Europa Clipper, and Europa Lander). A further understanding of

Observation of nuclear quantum effects and hydrogen bond symmetrisation in high pressure ice

open access: yesNature Communications, 2018
Hydrogen atoms in water ices, under pressures at which they might exist in ocean exoplanets and icy moons, exhibit dynamics that are still poorly understood. Here, 1H-NMR experiments approaching the Mbar range shed light on the symmetrisation of hydrogen

Near-Infrared reflectance spectroscopy of sublimating salty ice analogues. Implications for icy moons [PDF]

open access: yes, 2021
The composition of the surface of the Galilean icy moons has been debated since the Galileo mission. Several chemistries have been proposed to explain the composition of the non-icy component of the moon's surfaces, notably, sulphuric acid hydrates and magnesium and sodium sulphates.

Assessing release strategies for reintroductions of endangered Wyoming toads

open access: yesWildlife Society Bulletin, Volume 46, Issue 5, December 2022., 2022
We performed reintroductions of captive‐bred Wyoming toads (Anaxyrus baxteri) (photo B.) to test the effects of soft‐ and hard‐release methods through implementation of a delayed‐release. After release, the toads were tracked using a harmonic tracking system in Wyoming, USA. The soft‐released toads were held in an outdoor enclosure for 14 days prior to

Abrupt climate transition of icy worlds from snowball to moist or runaway greenhouse [PDF]

open access: yesNature Geoscience, 10, 556-560, Aug. 2017, 2018
Ongoing and future space missions aim to identify potentially habitable planets in our Solar System and beyond. Planetary habitability is determined not only by a planet's current stellar insolation and atmospheric properties, but also by the evolutionary history of its climate.

The potential for tidally heated icy and temperate moons around exoplanets [PDF]

open access: yesAstrophys.J.648:1196-1205,2006, 2006
Moons of giant planets may represent an alternative to the classical picture of habitable worlds. They may exist within the circumstellar habitable zone of a parent star, and through tidal energy dissipation they may also offer alternative habitable zones, where stellar insolation plays a secondary, or complementary, role.

Partnering with people living with dementia and care partners in technology research and design: Reflections and recommendations

open access: yesAustralian Occupational Therapy Journal, Volume 69, Issue 6, Page 723-741, December 2022., 2022
Abstract Introduction Occupational therapists may recommend and support technology use for facilitating independence, safety, wellbeing, and participation. There are high expectations for technology for people living with dementia. However, there is recognition that technologies will need to improve to deliver these expected benefits.

Timing and Abundance of Clathrate Formation Control Ocean Evolution in Outer Solar System Bodies: Challenges of Maintaining a Thick Ocean within Pluto

open access: yesThe Planetary Science Journal, 2023
Clathrate hydrates may represent a sizable fraction of material within the icy shells of Kuiper Belt objects and icy moons. They influence the chemical and thermal evolution of subsurface oceans by locking volatiles into the ice shell and by providing ...

Possibility for albedo estimation of exomoons: Why should we care about M dwarfs? [PDF]

open access: yesA&A 592, A139 (2016), 2016
Occultation light curves of exomoons may give information on their albedo and hence indicate the presence of ice cover on the surface. Icy moons might have subsurface oceans thus these may potentially be habitable. The objective of our paper is to determine whether next generation telescopes will be capable of albedo estimations for icy exomoons using ...

Dust and Snow Cover on Saturn's Icy Moons [PDF]

open access: yesGeophysical Research Letters, 2019
AbstractThe final analysis of the Cassini radar observations of Saturn's icy moons presented here shows that the exchange of material between the planet's dust rings and moons, which is specific to the Saturnian system, plays a key role in the current state of the airless satellite regolith.
