The Daya Bay Neutrino Experiment has produced the most precise measurement yet of theta13, a key parameter for understanding how neutrinos change their flavor.
Astronomers connect the dots between two strange doppelganger galaxies, uncovering what might be a string of galactic pearls created in a cosmic collision 8 billion years ago.
The result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies.
New results from the world’s most sensitive dark matter detector put the best-ever limits on particles called WIMPs, a leading candidate for what makes up our universe’s invisible mass.
