- Researchers studied whether AI models understand the real world.
- Most chatbots learn from very large internet text collections.
- That text contains facts, errors and strange nonsense.
- Scientists gave simple sentences to each model for testing.
- Sentences showed common, unlikely, impossible and nonsensical events.
- The AI produced internal states that researchers studied.
- Large models had clear patterns that matched human judgments.
- The study may help build smarter, more trustworthy AI.
- Results were shown across several open-source AI models.

Researchers Call for Clear Rules on Gene-Edited Crops in Mexico
Mexican researchers want rules that distinguish gene-edited crops from GMOs. They launched a petition asking the government for evidence-based regulation while warning a March decree banning genetically modified maize could also affect gene editing.
Decaying dark matter may explain early giant black holes
Researchers propose that tiny energy from decaying dark matter changed gas chemistry in the first galaxies. This could let some gas clouds collapse directly into massive black holes, helping to explain early observations by the James Webb Space Telescope.
New analysis: Titan may have a slushy interior, not a deep ocean
Reanalysis of Cassini data suggests Titan has a thick, slushy layer with tunnels and pockets of meltwater near a rocky core rather than a single deep ocean. The result could change ideas about habitability and will be testable by the Dragonfly mission.
