Faster-than-light darkness, evolving humans, and fatter polar bears headline this week in science
This week’s science roundup covers the first observation of singularities in combined light and sound waves traveling faster than light, the discovery of quantum entanglement between moving atoms, ongoing debates about the universe’s expansion and a seven‑dimensional twist to Hawking’s information paradox, new evidence that natural selection has continued shaping West Eurasians over the last 10,000 years (traits like lighter skin and red hair), and reports that some polar bears are adapting to melting habitats by getting fatter, highlighting a broad mix of physics, cosmology, evolution, and wildlife research.
