Nearby Supernova Factory Turns On
This large Chandra image shows the Carina Nebula, a star-forming region in the Sagittarius-Carina arm of the Milky Way a mere 7,500 light years from Earth. Chandra's sharp X-ray vision has detected over 14,000 stars in this region, revealed a diffuse X-ray glow, and provided strong evidence that massive stars have already self-destructed in this nearby supernova factory.

Packaging Process for Genes Discovered in New Research
Like a strand of white pearls, DNA wraps around an assembly of special proteins called histones (colored) to form the nucleosome, a structure responsible for regulating genes and condensing DNA strands to fit into the cell's nucleus. Credit: Karolin Luger
New Technique Sheds Light on the Mysterious Process of Cell Division
Asymmetric division of a primitive model cell composed of a lipid membrane that encapsulates a polymer solution.
Zombie Ants Have Fungus on the Brain, New Research Reveals
