A novel approach for distinguishing noise and information in forest MLS‐point clouds

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1595-1605, May 2026.
Abstract 3D laser scanning is a cornerstone of modern forest and ecological research, allowing detailed insight into forest structures and dynamics. Although point cloud processing and noise management are crucial steps in the exploitation of LiDAR data, traditional denoising methods are usually based on the assumption of a Gaussian noise distribution,

Ascites circRNA ASCOR Drives Platinum Resistance of High‐Grade Serous Ovarian Cancer by Facilitating RPA1 Nuclear Translocation

Advanced Science, Volume 13, Issue 23, 23 April 2026.
High‐grade serous ovarian carcinoma (HGSOC) is plagued by platinum resistance, with malignant ascites closely linked to poor outcomes. Here, we identify ASCOR, a circRNA enriched in ascites small extracellular vesicles (sEVs) from platinum‐resistant HGSOC patients, as a predictor of poor survival. ASCOR enhances platinum resistance in vitro and in vivo

Tracking tau and cellular responses in human iPSC‐microglia: from uptake to seedable secretion, including in extracellular vesicles

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Microglia have been implicated in the templated spread of tau aggregates in tauopathies through mouse studies. However, it is unclear whether these findings translate to human disease. METHODS We challenged human induced pluripotent stem cell (iPSC)‐derived microglia‐like‐cells (iMGL) with monomeric and fibrillar recombinant tau ...

Advances in CRISPR Base Editing: From Molecular Evolution to Therapeutic Applications in Genomic Medicine

Journal of Cellular and Molecular Medicine, Volume 30, Issue 8, April 2026.
ABSTRACT CRISPR‐Cas9 systems revolutionized gene editing, but inherent drawbacks, namely DNA double‐strand breaks (DSBs) and the difficulty of achieving precise repairs (due to low HDR efficiency), led researchers to invent new, more accurate gene editing tools.
