Mid-infrared Measurements of Ion-irradiated Carbonaceous Meteorites: How to Better Detect Space Weathering Effects

The Planetary Science Journal
Remote sensing study of asteroids will soon enter a new era with an increasing amount of data available thanks to the JWST, especially in the mid-infrared (MIR) range that allows identification of mineral species.

Dust Plumes Induced by a Time‐Varying Electron Beam

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We present laboratory results to address dust charging and lofting on the Moon and other airless planetary bodies in response to time‐varying solar wind and ultraviolet (UV) exposure. In these experiments, dust is exposed to an electron beam that varies in beam energy between 40 and 260 eV as a function of time.

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

Advanced Science, Volume 13, Issue 58, 19 October 2026.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.

Detection of a 2.85 μm Feature on Five Spinel-rich Asteroids from JWST

The Astrophysical Journal Letters
Ground-based observations of “Barbarian” L-type asteroids at 1–2.5 μ m indicate that their near-infrared spectra are dominated by the mineral spinel, which has been attributed to a high abundance of calcium-aluminum inclusions (CAIs)—the first solids to ...

Evaluation of simulated space weathering-based meteorite alteration and potential influence on mechanical deformation of rubble pile asteroids

Frontiers in Astronomy and Space Sciences
Asteroids with the potential to impact Earth have become a significant focus of scientific research and applied space technology. These bodies are expected to be key targets for mitigation actions and space mining activities in the coming decades ...

Network‐dependent remote effects and local tau burden jointly shape neuronal dysfunction in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract BACKGROUND Tau pathology in Alzheimer's disease (AD) propagates along the brain's connectome, yet the mechanisms by which tau drives neuronal dysfunction remain unclear. We hypothesized that dysfunction primarily emerges in regions close to tau‐harboring epicenters. METHODS One hundred thirty‐one amyloid‐positive individuals underwent dynamic [

Rotationally Resolved Near-infrared Spectroscopy of Three Large Eurybates Family Members

The Planetary Science Journal
The Eurybates family is the largest collisional family in the Jupiter Trojan population. Previous visible spectroscopy of asteroid (3548) Eurybates has shown potential surface heterogeneity due to rotation of the asteroid.
