- Robot, can you say ‘Cheese’ | Columbia engineers build Emo, a silicon-clad robotic face that makes eye contact and uses two AI models to anticipate and replicate a person’s smile before the person actually smiles https://www.engineering.columbia.edu/news/robot-can-you-say-cheese 6 comments technology
- Scientists unveil Emo, a robot that anticipates facial expressions and executes them simultaneously with a human. It has even learned to predict a forthcoming smile about 840 milliseconds before the person smiles, and to co-express the smile simultaneously with the person. https://www.engineering.columbia.edu/news/robot-can-you-say-cheese 198 comments science

- A newly developed AI program has seemingly discovered its own alternative physics. After being shown videos of physical phenomena on Earth, the AI didn't rediscover the current variables we use; instead, it actually came up with new variables to explain what it saw. https://www.engineering.columbia.edu/news/lipson-chen-ai-alternative-physics 72 comments science
- A Robot Learns to Imagine Itself. The robot created a kinematic model of itself, and then used its self-model to plan motion, reach goals, and avoid obstacles in a variety of situations.

- Some Amazon rainforest regions are more resistant to climate change than previously thought. It was thought that dry air limits photosynthesis, but in these wet regions, photosynthesis and carbon uptake actually increase when the air is drier, as plants generate more efficient leaves in response. https://www.engineering.columbia.edu/press-releases/gentine-climate-change-rainforest-regions 17 comments science
