Case for Dark Matter Signal Strengthens

A new analysis strengthens the case that gamma rays emanating from the center of the Milky Way come from dark matter particles known as WIMPs.


Search Escalates for Key to Why Matter Exists

Physicists have completed a new round of searches for the answer to why matter dominates over antimatter. But the radioactive decay that would solve the puzzle is evading them.
