A new technology has been developed that enables pretrained AI models to be expanded into larger models with specialized expert modules, without training the models from scratch.

A research team led by Senior Researcher Seongsik Park of the Semiconductor Technology Research Division at the Korea Institute of Science and Technology (KIST; President Oh Sang-rok) announced that it has developed "A²SG," a new learning technique that enhances the learning performance of SNNs. This research was accepted as a regular paper at ICML 2026, one of the world's top three artificial intelligence conferences, and was presented on Tuesday, July 7, at the conference (July 6-11, COEX, Seoul)-the first time in the conference's history that it was held in South Korea.

The Hebrew University of Jerusalem proudly congratulates Prof. Haim Sompolinsky, one of the world's leading theoretical physicists and neuroscientists, on being awarded the 2026 Dirac Medal and Prize by the Abdus Salam International Centre for Theoretical Physics (ICTP).

Professor Jun Ma's research group at the University of Science and Technology of China reported a novel green ammonia synthesis strategy based on high-energy electron beam dissociation collisions. This work utilizes a MeV-level electron beam to directly act on an N₂/H₂ gas-phase system, achieving ammonia generation at room temperature, atmospheric pressure, and without an external heating source. The study shows that the high-energy electron beam can activate stable N≡N triple bonds through ionization, excitation, and secondary electron induction processes, driving the conversion of nitrogen and hydrogen into NH₃. In the catalyst-free system, an ammonia generation rate of 0.14 μmol·L⁻¹·s⁻¹ can be obtained by optimizing the electron beam parameters; further, the introduction of Ru nanocatalysts increases the ammonia yield by up to 2.8 times compared to the catalyst-free system. This work provides a new research approach for achieving small molecule activation and green ammonia synthesis using high-energy electron beams. The article was published as an open access Research Article in CCS Chemistry, the flagship journal of the Chinese Chemical Society.
