Artificial intelligence is entering a new phase in which generating content is no longer the difficult part. The harder question is determining where that content came from. Anthropic, the company behind Claude, is now introducing watermarking technology for AI-generated text and digitally signed provenance information for generated files. The move is closely connected to new European Union transparency requirements and could become an important milestone in the broader effort to distinguish...

The artificial intelligence boom is creating a hardware problem that software alone cannot solve. As AI models become larger, inference workloads become more intensive, and data centers deploy increasingly powerful accelerators, the amount of heat generated by computing infrastructure has become a critical engineering challenge. Cooling that hardware requires additional energy, infrastructure, and capital, creating a feedback loop in which the technology powering AI also increases the...

A fundamental problem in semiconductor engineering is becoming increasingly important as artificial intelligence demands ever larger amounts of memory and computing power: how much physical charge is actually necessary to store one bit of information? Modern memory technologies typically use far more than the theoretical minimum because electronic signals become increasingly difficult to distinguish as the amount of stored charge decreases. A research team in China has now demonstrated a...
