I am pretty impressed to Gemini 3. It is the first AI I am scared of. We dont probably need human researchers to find a scientific question anymore. Only lab rats and field explorers will survive this major extinction. Good luck.

Hey Nano-Banana, please super-resolution and enhance this low-resolution satellite image. Make it like the imagery from the state-of-the-art 10-cm resolution satellite. Strictly keep the composition and viewing angle of the original image. Add immence details to the original blurry image. 😱😱

Yes. Drown to death in tsunami is not the ordinally drowning. In most cases, it is an agonal death with uncountable traumas. Never, never caught by tsunami.

My mother often recalled the tsunami of 1960 Chile Earthquake (M9.5) in Japan. She was a teenager at that time. She witnessed the river reversely flowing and woods and waters blocking lowlands. The flooding persisted for the entire day. The distant EQ do cause a significant damage through tsunami.
