Acoustic Sensing as a Tool for Brain Tumor Diagnostics
Advanced Sensor Research, Volume 5, Issue 2, February 2026.Surface acoustic wave (SAW) sensing is used to distinguish non‐neoplastic brain tissue from primary and metastatic tumors based on their acoustic attenuation signatures. Ex vivo human brain samples reveal clear tissue‐specific mechanical profiles, correlating with stiffness and malignancy.

Animal‐mediated seed dispersal: A review of study methods
Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.
