What's happened
Researchers at the University of Reading have developed a hydrogel that can play the video game Pong and improve its performance over time. This breakthrough suggests that even simple materials can exhibit adaptive behaviors typically associated with living systems or advanced AI, opening new avenues for smart material development.
Why it matters
What the papers say
According to The Independent, Dr. Yoshikatsu Hayashi stated, "Our research shows that even very simple materials can exhibit complex, adaptive behaviours typically associated with living systems or sophisticated AI." This sentiment is echoed in the coverage by Ars Technica, where Hayashi emphasizes the potential for developing new types of smart materials. Meanwhile, Sky News highlights the gel's ability to improve its performance over time, noting that it gains a form of 'muscle memory' through electrical stimulation. The Guardian adds that while the hydrogel is not sentient, it demonstrates a memory that allows it to enhance its gameplay, suggesting exciting possibilities for future applications in AI and robotics.
How we got here
This research builds on previous studies where brain cells were taught to play Pong. The current study explores how hydrogels, which are soft and flexible materials, can also learn and adapt through electrical stimulation, demonstrating a form of memory.
