Unraveling Chronic Pain: From Mechanisms and Risks to Diagnosis and Treatment
MedComm, Volume 7, Issue 4, April 2026.Chronic pain arises through distinct molecular pathways categorized into nociceptive, neuropathic, and nociplastic types. Nociceptive pain begins with TRP channel activation in peripheral nociceptors, signaling via Aδ‐ and C‐fibers through the spinal dorsal horn and spinothalamic tracts to the brain, regulated by descending inhibition and involving ...

Torque‐Transmitting Architected Metamaterials for Flexible and Extendable Tubular Robotics
Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.Soft and continuum robots commonly rely on fluid, tendon, or rod‐based power transmissions, to control robotic form and actuation. This study presents an architected structure, based on patterned straight‐line mechanisms, that enables simultaneous bending, extending, and torsionally rigid (BETR) transmission.
