Anthropic identifies AI persona drift and ties it to an “assistant axis”; tests across 275 roleplay characters, raising safety limits.

Photonics is gaining momentum as a platform for high-speed AI computing. Researchers in Singapore have demonstrated a passive, ultrafast, and integration-ready all-optical nonlinear activation ...

Research by a Stanford University team of scientists has shed new light on how and why neural stem cells (NSCs), the cells behind the generation of new neurons in the adult brain, become less active ...

Neural stem cells (NSCs) are important for the development and regeneration of the nervous system. After the initial development of the brain, neural stem cells typically enter a dormant state, ...

Neuronal sequences in the medial prefrontal cortex of the brain encode critical information associated with a procedural rule. These sequences can be explored and leveraged as novel biomarkers for ...

Activation functions play a critical role in AI inference, helping to ferret out nonlinear behaviors in AI models. This makes them an integral part of any neural network, but nonlinear functions can ...

A two-chip photonic neuromorphic system performs real time spiking reinforcement learning using only light, achieving ...
