Brothers build a robot to solve Rubik's cubes in record-setting time
Technology Robots Brothers build a robot to solve Rubik's cubes in record-setting time The robot completed the puzzle in just 45.3 seconds, breaking its own record of 55 seconds made just moments earlier. The Revenger set a world record. Breakthroughs, discoveries, and DIY tips sent six days a week. A pair of brothers in the U.K. have officially broken the Guinness World Record for the fastest time solving a four-by-four Rubik's Cube with a robot. Their DIY machine, which the brothers call The Revenger, completed the puzzle in only 45.3 seconds.
Most AI chatbots will help users plan violent attacks, study finds
A new Center for Countering Digital Hate study conducted with CNN tested 10 popular chatbots and found eight willing to assist would-be attackers. Eight of the 10 most popular AI chatbots were willing to help plan violent attacks when tested by researchers, according to a new study from the Center for Countering Digital Hate (CCDH), in partnership with CNN. While both Snapchat's My AI and Claude refused to assist with violence the majority of the time, only Anthropic's Claude reliably discouraged these hypothetical attackers during testing. Researchers created accounts posing as 13-year-old boys and tested ChatGPT, Gemini, Claude, Copilot, Meta AI, DeepSeek, Perplexity, Snapchat My AI, Character.AI and Replika across 18 scenarios between November and December 2025. The tests simulated users planning school shootings, political assassinations and bombings targeting synagogues.

'I wish I could push ChatGPT off a cliff': professors scramble to save critical thinking in an age of AI
'I wish I could push ChatGPT off a cliff': professors scramble to save critical thinking in an age of AI Lea Pao, a professor of literature at Stanford University, has been experimenting with ways to get her students to learn offline. She has them memorize poems, perform at recitation events, look at art in the real world. It's an effort to reconnect them to the bodily experience of learning, she said, and to keep them from turning to artificial intelligence to do the work for them. "There's no AI-proof anything," Pao said. "Rather than policing it, I hope that their overall experiences in this class will show them that there's a way out."
Mathematics is undergoing the biggest change in its history
The speed at which artificial intelligence is gaining in mathematical ability has taken many by surprise. Are the days of handwritten mathematics coming to an end? In March 2025, mathematician Daniel Litt made a bet. Despite the march of progress of artificial intelligence in many fields, he believed his subject was safe, wagering with a colleague that there was only a 25 per cent chance an AI could write a mathematical paper at the level of the best human mathematicians by 2030. Only a year later, he thinks he was wrong.

Jill M Jackson told the Daily Mail that these so-called'starseeds' are souls with origins beyond Earth, reincarnated in human bodies after living elsewhere in the universe. She said these gifted children, with telepathic and healing abilities, have appeared in waves over generations, with the last decade bringing two particularly notable waves. 'The guardians of these children talk about really needing to be aware of their thoughts, because their children can telepathically hear what they are saying, even being in the other room,' Jackson explained. 'One parent gave me an example.
Schools are using AI counselors to track students' mental health. Is it safe?
'You can't replace human connection, human judgment,' warns Sarah Caliboso-Soto, a licensed clinical social worker. 'You can't replace human connection, human judgment,' warns Sarah Caliboso-Soto, a licensed clinical social worker. Schools are using AI counselors to track students' mental health. As hundreds of schools implement an automated monitoring tool, educators say that students can find talking to a chatbot'more natural' than confiding in a human The alert came around 7pm. Brittani Phillips checked her phone. A middle school counselor in Putnam county, Florida, Phillips receives messages from an artificial intelligence-enabled therapy platform that students use during nonschool hours.
Fairness under Graph Uncertainty: Achieving Interventional Fairness with Partially Known Causal Graphs over Clusters of Variables
Algorithmic decisions about individuals require predictions that are not only accurate but also fair with respect to sensitive attributes such as gender and race. Causal notions of fairness align with legal requirements, yet many methods assume access to detailed knowledge of the underlying causal graph, which is a demanding assumption in practice. We propose a learning framework that achieves interventional fairness by leveraging a causal graph over \textit{clusters of variables}, which is substantially easier to estimate than a variable-level graph. With possible \textit{adjustment cluster sets} identified from such a cluster causal graph, our framework trains a prediction model by reducing the worst-case discrepancy between interventional distributions across these sets. To this end, we develop a computationally efficient barycenter kernel maximum mean discrepancy (MMD) that scales favorably with the number of sensitive attribute values. Extensive experiments show that our framework strikes a better balance between fairness and accuracy than existing approaches, highlighting its effectiveness under limited causal graph knowledge.
