A review, published on September 11 in Cyborg and Bionic Systems by researchers at Tianjin University, summarizes recent advances in intracortical microstimulation (ICMS), a technique that uses tiny electrodes implanted in the brain to activate specific groups of neurons. The researchers discuss how ICMS has evolved from a tool for mapping brain function into a potential technology for sensory feedback, information delivery, closed-loop neuromodulation and biointegrated neural interfaces.

Brain–computer interfaces are increasingly being explored as a way to restore lost functions or provide new channels for communication between the nervous system and electronic devices. While much BCI research focuses on reading neural signals, ICMS provides the complementary ability to write information back into the brain.

“ICMS has emerged as a prominent invasive modality capable of activating intracortical neuronal populations with high precision,” the researchers write. The technology can potentially replace or supplement natural sensory inputs, probe

Thermochromic smart windows can automatically adjust solar and thermal radiation in response to temperature, offering a passive route to reduce building energy demand and improve indoor comfort. A new review published in Science Bulletin examines why these windows have not yet achieved large-scale application, despite rapid materials progress. The authors identify key challenges in spectral regulation, switching temperature, response speed, durability, scalable fabrication, glazing integration, lifecycle impacts, and building control. They argue that future development should shift from isolated material optimization toward deployment-oriented design and system-integrated adaptive building envelopes.

Rats and mice can scurry through dark and tight spaces with ease. In caves,  underground burrows, buildings or sewers. Their superpower for this are their whiskers. Now tiny autonomous drones could soon navigate through darkness, dust and smoke using artificial whiskers inspired by these animals. Their small size limits the use of large or heavy sensors for navigation. That's why researchers at Delft University of Technology (The Netherlands) have developed a lightweight whisker-based tactile sensor that enables drones to navigate and explore their surroundings through gentle touch. The study has been published in Nature Communications.

Against the backdrop of global food security facing the dual pressures of population growth and climate warming, the search for green, low-cost agricultural yield-enhancing technologies has become increasingly urgent. As a frontier technology in agricultural physical engineering, high-voltage electrostatic field (HVEF) has attracted considerable attention for its potential to regulate plant growth and development in a non-chemical manner.
