The Spatial Distribution of the Unidentified 2.07 μm Absorption Feature on Europa and Implications for its Origin

The Planetary Science Journal, 2023
A weak absorption feature at 2.07 μ m on Europa’s trailing hemisphere has been suggested to arise from radiolytic processing of an endogenic salt, possibly sourced from the interior ocean.

Chemical Kinetics Simulations of Ice Chemistry on Porous Versus Non-Porous Dust Grains

Frontiers in Astronomy and Space Sciences, 2021
The degree of porosity in interstellar dust-grain material is poorly defined, although recent work has suggested that the grains could be highly porous.

Thermal Stability of Ice at Shackleton Crater: Implications for Water Ice Detection for the Chang’E-7 Mission

The Planetary Science Journal
The candidate landing region for China’s Chang’E-7 (CE-7) lunar exploration mission is near Shackleton crater at the lunar south pole, and the CE-7 mission will perform in situ detection of water ice.

Heterogeneous Nucleation of Ice on Carbon Surfaces

Journal of the American Chemical Society, 2014
Atmospheric aerosols can promote the heterogeneous nucleation of ice, impacting the radiative properties of clouds and Earth's climate. The experimental investigation of heterogeneous freezing of water droplets by carbonaceous particles reveals widespread ice freezing temperatures.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Acidification and its effect on the ecosystems of the ICES Area [PDF]

, 2011
This focuses on the impacts of ocean acidification (OA) on ecosystems and higher trophic levels in the ICES Area. One of ICES distinguishing features is its access to scientists across the entire marine field.

The Challenge of Icy Sample Return Begins With Artemis

Geophysical Research Letters
Throughout the Solar System, volatiles are found as solid ices. Returning ices to Earth for scientific analysis is critical to understanding the formation of a Solar System that bears life.

Pluto’s Surface Mapping Using Unsupervised Learning from Near-infrared Observations of LEISA/Ralph

The Planetary Science Journal, 2023
We map the surface of Pluto using an unsupervised machine-learning technique using the near-infrared observations of the LEISA/Ralph instrument on board NASA’s New Horizons spacecraft.
