A new study of stickleback fish in Japan shows that the 2011 tsunami briefly accelerated hybridization between closely related species by reshaping coastal habitats and forcing populations into contact. But the genetic evidence suggests that, despite the upheaval, species boundaries remained largely intact as natural selection rapidly purged most hybrid ancestry.

Researchers have identified an unusual deep-sea formation in the South China Sea that has been described as a ādragonballā structure, adding a striking new data point to the study of one of the worldās least understood marine environments. While the finding is not a clean-energy breakthrough in itself, it underscores how much remains unknown about the ocean systems that regulate climate, store carbon, and shape the planetās energy balance.

The worldās largest freshwater lake is showing measurable signs of recovery after decades of ecological stress, according to new reporting highlighted by Phys.org. The rebound offers a rare climate and water-management bright spot, but experts caution that the lakeās long-term stability will depend on sustained action against pollution, overuse, and warming-driven volatility.
