Dark matter—the unseen stuff that makes up more than four-fifths of the matter in the universe—is finally coming into view. What we see may change our entire picture of reality.
A new partnership between scientists from US institutions and CERN could improve results from neutrino experiments around the world. The scientists hope to use equipment at CERN to gain a more precise understanding of the process of creating a neutrino beam.

Space telescopes have greatly advanced our understanding of the universe, but they have also surfaced some new and puzzling problems. Recently scientists gained insight into a mismatch between theory and observation uncovered by space telescope research by using a ground-based X-ray technology that grew out of particle physics.

Many have speculated about which theorists the Nobel Committee might honor for the prediction of the Higgs boson, but it was the experimentalists involved in the search for the particle who received recognition today. 
Decay channels are the possible transformations a particle can undergo as it decays.
When a particle decays, it does not break into smaller bits; its energy does. Even fundamental particles—so named because they are the basic building blocks of matter that cannot be broken into smaller parts—can decay. Many particles in the Standard Model exist for only a limited time before decaying.
When a particle decays, it transforms into collections of less massive particles whose combined energy adds up to the energy of the original particle.
In its infancy, the universe was made of nearly equal parts matter and antimatter. Yet matter overwhelmingly dominates today. Scientists design experiments that examine the conditions of the early universe to investigate why.
An international collaboration of scientists proposed to build one such project, a particle collider that would specialize in creating B mesons, in Italy over the next several years. However, last week the Italian government withdrew funding for the project, citing the country's weakened economic state.
On Friday night, Nov. 16, about 1000 people came out to Fermilab to see five physicists duke it out... with science.
The occasion was the laboratory's first ever . A physics slam is kind of like a poetry slam—the five contestants were given 12 minutes each to explain a complex particle physics concept to an auditorium filled with laymen. And they had to do it in the most entertaining way they could, because audience applause determined the winner.

Astronomers have used NASA's Chandra X-ray Observatory to find evidence our Milky Way Galaxy is embedded in an enormous halo of hot gas that extends for hundreds of thousands of light years.
