"Uninfluential Black Hole and Adorable Bug: Saturday's Galactic Discoveries"

Researchers study an anemic blue compact dwarf galaxy, I Zwicky 18, using the James Webb Telescope, finding extreme populations of massive stars and large supershells of dust and ionized gas. A new genus of fluffy longhorn beetle, Excastra albopilosa, is discovered in Australia, possibly evolving its fuzzy coat as a predator deterrent. Astronomers report that quasar H1821+643, located 3.4 billion light-years from Earth, has little influence on its surroundings compared to other black holes. Duke University researchers develop a technique to capture high-definition images of mouse placental development, tracking blood vessel size and density, and oxygen levels from early to late pregnancy stages.
