Technical Feasibility Study of Autonomous Field Robot‐Based on‐the‐go Assessment of Soil Nutrients Using Ion‐Sensitive Field‐Effect Transistors

open access: yesAdvanced Robotics Research, EarlyView.
Autonomous field robots equipped with ISFET‐based sensors enable rapid, spatially resolved soil nutrient analysis directly in the field. An automated system based on the BoniRob platform is presented for standardized on‐site extraction and measurement of key macronutrients and soil pH.

Underground Signals: The Ecological Power of Root Volatiles

open access: yesAdvanced Science, EarlyView.
Root volatiles mediate rhizosphere chemical communication, shaping interactions among plants, microbes, herbivores, and natural enemies. Their production, transport, and perception underpin ecological adaptation, multitrophic interactions, and plant resilience, offering opportunities for sustainable crop protection, resilient agroecosystems, and ...

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

open access: yesAdvanced Science, EarlyView.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Single‐Stranded Interruptions in the T7 Promoter Non‐Template Strand Exhibit Unexpected Transcription Behavior

open access: yesAngewandte Chemie, EarlyView.
DNA structures with short single‐strand gaps in the non‐template strand of the T7 promoter prevent transcription by T7 RNA polymerase. Contrary to intuition, however, transcriptional activity can be observed again when the size of the gap increases toward the transcription start site, thereby reducing the proportion of double‐stranded DNA in the ...

Osseoperceptive EMG Feedback Improves Grasp Force Control in Myoelectric Prosthetic Hands

open access: yesAdvanced Science, EarlyView.
Osseoperception is explored as a non‐invasive pathway for delivering sensory feedback in myoelectric prosthetic control. By encoding the user's electromyographic (EMG) signal through bone‐conducted stimulation, this approach enables predictive grasp force regulation.
