DURING our discussion at workshops for writing“What Does ChatGPT Say:The DAO from Algorithmic Intelligence to linguistic Intelligence”[1],we had expected the next milestone for Artificial Intelligence(AI)would be in the direction of Imaginative Intelligence(II),i.e.,something similar to automatic wordsto-videos generation or intelligent digital movies/theater technology that could be used for conducting new“Artificiofactual Experiments”[2]to replace conventional“Counterfactual Experiments”in scientific research and technical development for both natural and social studies[2]-[6].Now we have OpenAI’s Sora,so soon,but this is not the final,actually far away,and it is just the beginning.

As an effective strategy to improve the properties of electrocatalysts,magnetic field-assisted electrocatalytic water splitting has attracted increasing attention ***,the corresponding enhancements mostly depend on the exertion of an external magnetic field during electrochemical reactions,which results in a high cost of industrial production,and makes the magnetic field manipulation of electrocatalysis become a challenging *** this work,instead of the external magnetic field,a bias magnetic field is self-supplied by the remanence state of a ferromagnetic electrocatalyst of *** to the assistance of this bias magnetic field,the FePt film in the remanence state shows the overpotential of 229 mV during hydrogen evolution reaction,which is much lower than that in its demagnetization state(283 mV).Our findings demonstrate that the remanence in ferromagnetic electrocatalysts can improve the catalytic performance,which is attributed to the decrease in domain walls.

Dear Editor,Gliomas are the most prevalent malignant tumors affecting the central nervous system (CNS), categorized into low-grade gliomas (LGG) comprising CNS WHO grades 2–3, and high-grade gliomas(HGG) encompassing CNS WHO grade 4(Aldape et al., 2015). The current standard therapeutic approach involves maximal safe margin excision followed by radiotherapy and temozolomide (TMZ)treatment (Armstrong et al., 2020).However, due to the unique site and microenvironment of gliomas, patients experience limited benefits from emerging revolutionary therapies such as targeted therapy and immunotherapy (Sampson et al., 2020; Yang et al., 2022).
