AI enhances satellite imagery to know what's happening "between the pixels"

Satellites provide a wide picture, but sometimes with limited resolution: the pixel is too large, and the details on the ground are lost. This is where downscaling comes in: using computational models to estimate temperature in more detail.

When the machine wears a lab coat: Artificial intelligence enters the lab

The story of artificial intelligence is no longer just about automation and process optimization, but about changing the way we work: models that identify hidden patterns, formulate hypotheses, and accelerate discovery in science and medicine.
Image caption: Princeton researchers have found that the prefrontal cortex of primates reuses modular thinking blocks to solve similar tasks. This gives biological brains a flexibility that artificial intelligence still lacks. The insight could help improve AI systems so that they retain old skills even as they learn new ones.

The brain has a shortcut to learning that artificial intelligence can't copy

Researchers have found that the brain repeatedly relies on the same cognitive “building blocks” when performing different types of tasks. By reassembling these blocks in new ways, the brain can rapidly generate behaviors
