Humanoid robots struggling with tasks like grasping a cup have a new teacher — a person wearing an ultrasound wristband that captures the movement of muscles, tendons and ligaments beneath the skin. Researchers at the Massachusetts Institute of Technology developed the tool to collect data of human hand motion that could eventually help robots achieve the dexterity that has been difficult for machines to master. As much of the tech world is still captivated with artificial intelligence assistants that are taking on computer-based tasks, the researchers are among the scientists trying to imbue AI with more sensory data from the physical world.

OpenAI has filed preliminary paperwork to potentially become a publicly traded company. The company announced Monday it has submitted confidential documents to the U.S. Securities and Exchange Commission. OpenAI says it hasn't decided on timing yet, as there are advantages to staying private. This move follows Anthropic's June announcement of its own IPO plans. Both companies are following SpaceX, which is also pursuing an IPO. OpenAI CEO Sam Altman mentioned last fall that an IPO was the “most likely path” due to the company's size and capital needs.

Apple is unveiling new artificial intelligence features at its annual developers conference. The World Wide Developers Conference started Monday. It's the last one featuring CEO Tim Cook before he turns his post over to John Ternus in September. The conference attracts thousands of developers from some 65 countries to Apple’s Silicon Valley headquarters. It usually focuses on software, in contrast to the fall unveiling of the latest iPhones. Apple showed off updates on new AI features, including upgrades to its Siri assistant. Apple says it's focusing on day-to-day use and privacy.

Anthropic is proposing that top AI companies coordinate a way to pause the development of advanced AI systems if they become too dangerous. The company behind the Claude chatbot says the technology is improving so quickly that there's a risk humans could lose control. In a blog post Thursday, Anthropic suggests giving the world an “option” to slow or temporarily pause AI development. The company plans to research ways to implement this pause, noting that AI models are getting faster, doubling their task capabilities every four months. This rapid advancement could lead to AI designing its own successors, raising control concerns.

Television and movie actors have voted to ratify a four-year contract with studios and streaming services. This comes after union leaders negotiated protections against synthetic actors created by artificial intelligence. The ratification was widely expected, and a strike like the one in 2023 never seemed likely during the drama-free negotiations. More than 90% of Screen Actors Guild-American Federation of Television and Radio Artists members approved the agreement. The new deal, like on recently reached by Hollywood writers, is for four years instead of the usual three. This provides extra labor stability in the industry. The contract includes provisions to keep the use of AI actors minimal.
