Extremists across the US have weaponized artificial intelligence tools to help them spread hate speech more efficiently, recruit new members, and radicalize online supporters at an unprecedented speed and scale, according to a new report from the Middle East Media Research Institute (MEMRI), an American non-profit press monitoring organization. The report found that AI-generated content is now a mainstay of extremists' output: They are developing their own extremist-infused AI models, and are already experimenting with novel ways to leverage the technology, including producing blueprints for 3D weapons and recipes for making bombs. Researchers at the Domestic Terrorism Threat Monitor, a group within the institute which specifically tracks US-based extremists, lay out in stark detail the scale and scope of the use of AI among domestic actors, including neo-Nazis, white supremacists, and anti-government extremists. "There initially was a bit of hesitation around this technology and we saw a lot of debate and discussion among [extremists] online about whether this technology could be used for their purposes," Simon Purdue, director of the Domestic Terrorism Threat Monitor at MEMRI, told reporters in a briefing earlier this week. "In the last few years we've gone from seeing occasional AI content to AI being a significant portion of hateful propaganda content online, particularly when it comes to video and visual propaganda. So as this technology develops, we'll see extremists use it more."

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts.
