A Third Star in the HAT-P-7 System and a New Dynamical Pathway to Misaligned Hot Jupiters
The Astrophysical JournalThe retrograde orbit of the hot Jupiter HAT-P-7b is suggestive of high-eccentricity (high-e) migration caused by dynamical interactions with a massive companion.

Thermal Segregation and Reddening in Europa's Double Ridges
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Europa's double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation‐driven darkening due to illumination and self‐heating—the process of thermal segregation. We apply an advanced 3D thermophysical model, including shadowing and self‐heating through mutual exchange of ...

Modeling the Detectability of Energetic Heliospheric Ions at Pluto During the New Horizons Flyby
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract We investigate the detectability of heliospheric helium ions at energies up to 100 keV by the New Horizons (NH) spacecraft during its flyby through Pluto's induced magnetosphere. The Pluto Energetic Particle Spectrometer Science Investigation energetic ion detector observed a reduction in their flux by an order of magnitude as the spacecraft ...

Archives of impact: The politics of craters on Earth
Geographical Research, Volume 64, Issue 2, May 2026.This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Most Hot Jupiters Were Cool Giant Planets for More Than 1 Gyr
The Astronomical JournalThe origin of hot Jupiters is the oldest problem in exoplanet astrophysics. Hot Jupiters formed in situ or via disk migration should be in place just a few million years after the formation of their host stars.

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1
British Journal of Pharmacology, Volume 183, Issue 9, Page 1845-1859, May 2026.Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...

Inhibitory Activity of Conferone on FAK Activity and Glutamine Metabolism in Human Colorectal Cancer
Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.ABSTRACT Colorectal cancer (CRC) is a major global cause of death, with metastases and chemotherapy resistance contributing to poor outcomes. To identify natural compounds with anticancer potential against CRC and elucidate their action mechanisms, the cytotoxicity of 37 natural compounds was evaluated against the HCT116, leading to the identification ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The oceanic tidal magnetic field, mainly driven by the circular orbital motion of the Moon, is an essential part of the time‐varying geomagnetic field. The previously adopted time‐harmonic (TH) base worked well in fitting the primary M2 ${M}_{2}$ tidal field, but extracting the other weaker modes like the N2 ${N}_{2}$ was difficult with only a
