New plasma stealth device targets specific areas, not entire aircraft. According to a recent report from the South China Morning Post, Chinese scientists and engineers claim to have developed a plasma stealth device for military aircraft that is capable of rendering nearly any such aircraft undetectable by radar.

The Canadian government plans to ban the Flipper Zero and similar devices after tagging them as tools thieves can use to steal cars.

Researchers say AI models like GPT4 are prone to “sudden” escalations as the U.S. military explores their use for warfare. --- - Researchers ran international conflict simulations with five different AIs and found that they tended to escalate war, sometimes out of nowhere, and even use nuclear weapons. - The AIs were large language models (LLMs) like GPT-4, GPT 3.5, Claude 2.0, Llama-2-Chat, and GPT-4-Base, which are being explored by the U.S. military and defense contractors for decision-making. - The researchers invented fake countries with different military levels, concerns, and histories and asked the AIs to act as their leaders. - The AIs showed signs of sudden and hard-to-predict escalations, arms-race dynamics, and worrying justifications for violent actions. - The study casts doubt on the rush to deploy LLMs in the military and diplomatic domains, and calls for more research on their risks and limitations.
