CriticGPT, Living Robot Skin, and Oyster-Inspired Concrete

Discover Daily by Perplexity

In this episode of Discover Daily, we explore OpenAI's CriticGPT, an AI model designed to identify errors in code generated by ChatGPT. CriticGPT catches 85% of errors compared to 25% by humans and its feedback was preferred over human critiques in 63% of cases. OpenAI plans to integrate CriticGPT into their AI training pipeline, potentially leading to more reliable AI models.
Next, we discuss a groundbreaking humanoid robot face created by scientists at the University of Tokyo and Harvard, covered in lab-grown, self-healing human skin cells. The innovative skin consists of human cells in a collagen scaffold on a 3D-printed resin base, enabling the robot to smile and display realistic facial expressions. This technology could revolutionize healthcare and cosmetics testing.
Finally, we explore how oyster-inspired concrete combines the durability of oyster shells with advanced engineering for stronger, eco-friendly building materials. Companies like GROW Oyster Reefs have developed concrete mixes that mimic oyster shells to sustain healthy oyster populations, while Princeton engineers created a cement composite inspired by mother of pearl that's 17 times more crack-resistant and 19 times more stretchable than standard cement. Oyster-inspired concrete promotes biodiversity, reduces erosion, and repurposes waste shells.
