Guide dogs are powerful allies, leading the visually impaired safely to their destinations, but they can’t talk with their owners—until now. Using large language models, a team of researchers at Binghamton University, State University of New York has created a talking robot guide dog system that determines an ideal route and safely guides users to their destination, offering real-time feedback along the way.

The paper, “From Woofs to Words: Towards Intelligent Robotic Guide Dogs with Verbal Communication,” was presented at the 40th Annual AAAI Conference on Artificial Intelligence (AAAI 2026)...

Modern life depends on fast and reliable wireless connections. Video calls, streaming services, virtual reality, and smart devices all place growing demands on networks that already serve billions of users. Most wireless data today travels through radio-based technologies such as Wi-Fi and cellular systems.

While these approaches have been highly successful, they face mounting challenges, including crowded radio spectrum, interference in dense indoor spaces, and rising energy consumption as more devices come online.

A promising complementary approach is optic...

While technology has made the world “smaller,” it has also pulled individuals apart, thanks to mobile phones and other devices that command our attention. Cornell University researchers are using technology, in the form of a mirror-equipped robot, to help bring people together. Members of the Architectural Robotics Lab, led by Keith Evan Green, have built a four-foot-tall robot—dubbed MirrorBot—with dual mirrors that, when placed in front of a pair of strangers, let each participant see themself in one mirror and the other person in the other.

In a study involving participants in a waiting-room setting, MirrorBot spurred conversations, playful excha...

The electronics inside your phone, your car, and every satellite currently orbiting Earth share one critical weakness: heat. Push them past about 200 degrees Celsius and they start to fail. For decades, that thermal ceiling has been one of the hardest walls in engineering. Now a team at the University of Southern California may have just found a way around it.

In a study published in Science, researchers led by Joshua Yang, Arthur B...
