Stratigraphy Preserved on the Jezero Crater Rim Reveals Repeated Impacts on Early Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract The outer slopes of the western Jezero crater rim are hypothesized to expose sections of Early‐ to Pre‐Noachian crust uplifted by the Jezero impact, providing an excellent opportunity to investigate the earliest geologic processes active on terrestrial planets.

Anthropogenic Pollution Accounts for a Substantial Part of Cloud Condensation Nuclei in North African Dust Layer

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Cloud condensation nuclei (CCN) modulate the properties and thus the climate effects of clouds. The North African dust plume is an important source of CCN in the North Atlantic trade‐wind zone. Yet, research into the nature and sources of these CCN is sparse, making it difficult to fully assess related cloud effects. Using combined airborne in

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...

Reduction in hippocampal cholinergic neurostimulating peptide enhances memory impairment in AppNL‐G‐F KI mice

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Whether cholinergic activity in the septohippocampal network affects cognitive dysfunction via hippocampal cholinergic neurostimulating peptide (HCNP) in Alzheimer's pathogenesis remains unclear. METHODS An Alzheimer's pathogenesis by mutation in amyloid‐beta precursor protein gene (AppNL‐G‐F) knock‐in (KI) and HCNP precursor ...
