The longevity of water ice on Ganymedes and Europas around migrated giant planets [PDF]
, 2017 The gas giant planets in the Solar System have a retinue of icy moons, and we expect giant exoplanets to have similar satellite systems. If a Jupiter-like planet were to migrate toward its parent star the icy moons orbiting it would evaporate, creating atmospheres and possible habitable surface oceans.

Different ice shell geometries on Europa and Enceladus due to their different sizes: impacts of ocean heat transport [PDF]
, 2022 On icy worlds, the ice shell and subsurface ocean form a coupled system -- heat and salinity flux from the ice shell induced by the ice thickness gradient drives circulation in the ocean, and in turn, the heat transport by ocean circulation shapes the ice shell.

A Passive Probe for Subsurface Oceans and Liquid Water in Jupiter's Icy Moons [PDF]
, 2014 We describe an interferometric reflectometer method for passive detection of subsurface oceans and liquid water in Jovian icy moons using Jupiter's decametric radio emission (DAM). The DAM flux density exceeds 3,000 times the galactic background in the neighborhood of the Jovian icy moons, providing a signal that could be used for passive radio ...

Geophysical Research Letters, 2023 Several bodies in the outer solar system are believed to host liquid water oceans underneath their icy surfaces. Knowledge of the hydrosphere properties is essential for understanding and assessing their habitability.

Inhalable Hsa‐miR‐30a‐3p Liposomes Attenuate Pulmonary Fibrosis
Advanced Science, EarlyView.The study explores inhalable hsa‐miR‐30a‐3p‐loaded liposomes as a treatment for bleomycin‐induced pulmonary fibrosis in mice. Hsa‐miR‐30a‐3p is electroporated into liposomes and formulated into a dry powder for inhalation. Delivered via dry powder inhalation, it improves pulmonary function, promotes myofibroblast de‐differentiation by targeting CNPY2 ...

A recent origin for Saturn's rings from the collisional disruption of an icy moon [PDF]
, 2017 The disruption of an icy moon in a collision with an interloping comet a few hundred million years ago is a simple way to create Saturn's rings. A ring parent moon with a mass comparable to Mimas could be trapped in mean motion resonance with Enceladus and Dione in an orbit near the current outer edge of the rings just beyond the Roche zone.

The Nuclear Receptor NR1B1/RARα Arrests the Differentiation of Anti‐Tumor Effector Cytotoxic T Cells
Advanced Science, EarlyView.RARα is highly expressed by differentiated effector and exhausted T cells and exerts a negative effect on effector T cell differentiation and the associated trafficking receptor switch. Upregulated RARα levels decrease the nuclear histone acetylase (HAT) activity, and this suppresses the expression of key Teff transcription factor BATF and trafficking ...
