Humans can create loose maps of environments they are exploring in their minds, using their senses and navigation skills. Many robots, on the other hand, rely on set maps of known environments or new maps produced using data collected by their sensors.

Anthropic chief executive Dario Amodei pitched investors on safety and a strict hiring culture on Friday, days before the AI company's stock market debut.

The use of algorithms to design structures has led to new parts optimized for ultralight aircraft, high-bandwidth antennas and F1 racing cars. But the best algorithmic design techniques still require lots of computation and time: Users only see the final design after it's complete, after which they often must start the design process all over again to make changes. That process also makes it harder to trust that the final designs are structurally sound.

People communicate with more than words. A raised hand, a change in posture or a facial expression can help convey meaning and emotion. Now, researchers have developed an artificial intelligence (AI) system that can translate speech into coordinated movements of the body, hands and face, potentially making digital characters and virtual presenters more expressive and lifelike.

Researchers at Keele University have developed a physics-inspired AI model that achieved high accuracy in tests distinguishing genuine facial images from AI-generated or manipulated images.
