Researchers have developed a programmable, multi-responsive soft actuator based on MXene materials that can reversibly deform under humidity, light, and magnetic fields. By introducing micro-ridge structures into a bilayer MXene/paraffin wax composite, the actuator enables controllable and complex shape transformations, offering new possibilities for soft robotics and intelligent devices.

Epilepsy affects millions of people worldwide, and roughly one-third of such patients continue to experience seizures despite medication. In a recent study, researchers from Gunma University have developed a 410-base pair compact genetic switch that selectively targets inhibitory neurons in the brain to restore the excitatory–inhibitory balance. This compact switch can be delivered using viral delivery vectors, enabling effective seizure suppression across multiple epilepsy mouse models while preserving the capacity of the therapeutic genes.

Learners often experience information overload when viewing and listening to presentations on PowerPoint. Addressing this, researchers in Japan proposed a ‘cumulative presentation’ design, in which visual content is segmented, and each segment appears alongside the relevant verbal explanation. By analyzing learners’ test scores and eye movements, researchers found that compared to the traditional format, in which information appeared all at once, cumulative presentation directed learners’ attention to relevant information and improved learning.
