Could AI understand emotions better than we do?

Thu, 05/22/2025 - 9:47am
Is artificial intelligence (AI) capable of suggesting appropriate behavior in emotionally charged situations? A team put six generative AIs -- including ChatGPT -- to the test using emotional intelligence (EI) assessments typically designed for humans. The outcome: these AIs outperformed average human performance and were even able to generate new tests in record time. These findings open up new possibilities for AI in education, coaching, and conflict management.

Infrared contact lenses allow people to see in the dark, even with their eyes closed

Thu, 05/22/2025 - 9:45am
Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision goggles, the contact lenses do not require a power source -- and they enable the wearer to perceive multiple infrared wavelengths. Because they're transparent, users can see both infrared and visible light simultaneously, though infrared vision was enhanced when participants had their eyes closed.
