How next-generation nuclear reactors are reshaping nuclear power design

New reactor designs are rethinking size, fuel, and cooling systems in an effort to make nuclear power cheaper, faster to build, and better suited to a changing energy landscape driven by climate goals and rising electricity demand.

Inside the new biology of vast artificial intelligence language models

Researchers at OpenAI, Anthropic, and Google DeepMind are dissecting large language models with techniques borrowed from biology and neuroscience to understand their strange inner workings and risks. Their early findings reveal city-size systems with fragmented “personalities,” emergent misbehavior, and new ways to monitor and constrain what these models do.
