USC Dornsife scientists have developed tools that can now interrupt specific links between neurons, called synapses, enabling targeted study of brain circuits. The method targets either excitatory or inhibitory synapses with molecular precision, leaving the rest of the neuron unharmed. The process is reversible, allowing researchers to study how specific circuits influence behavior, perception and neurological disorders. The technology could one day help guide therapies for conditions such as epilepsy, PTSD and addiction. 

POSTECH and Sogang University unveil battery innovation with double the energy density of conventional lithium-ion cells.

Focusing on the spatial cognitive capabilities of large language models (LLMs), researchers led by Prof. Danhuai Guo from Beijing University of Chemical Technology have introduced SRT4LLM, a standardized framework for testing the spatial cognition of LLMs. The framework systematically assesses LLMs across three key dimensions—spatial object types, spatial relations, and prompt engineering strategies—and establishes a unified testing process to support the development of native geographic LLMs.
