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.
Scientists on the ATLAS experiment explored the polarization of W bosons to test the Higgs mechanism and gain a deeper understanding of the first moments after the Big Bang.
Project Poltergeist led to the discovery of the ghostly particle. Sixty years later, scientists are confronted with more neutrino mysteries than ever before.
