MEMS‐Based Magnetoelectric Antennas for Wireless Power Transmission in Brain‐Implantable Devices
Advanced Materials Technologies, EarlyView.Magnetoelectric (ME) antennas allow the minimization of the invasiveness of brain implantable devices, via powering wirelessly systems able to actuate neural tissue. In order to achieve the necessary power efficiency transmission, the choice of the materials and the system assembly is vital.

From Rigid to Soft Robotic Approaches for Neuroendoscopy
Advanced Robotics Research, EarlyView.Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

A computer-based simulation of vacuum extraction during childbirth [PDF]
, 2014 Vacuum extraction is an instrumental method used in obstetrics when childbirth labour fails to progress. The instrument used during vacuum extraction is the ventouse. It comprises of a suction cup attached to the fetal scalp through a vacuum, and a chord

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Long‐Term Memory Updating Parallels Altered Awake and Sleep Hippocampal Replays
Advanced Science, EarlyView.This study introduces a behavioral paradigm for memory updating and reveals underlying hippocampal mechanisms. Replays of place cells predict future behavioral choices during behavior and show a bias toward high‐reward locations during non‐rapid eye movement (NREM) sleep, specifically within the memory updating process.

Advanced Science, EarlyView.Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.
