Scientists say collisions between dark matter particles might be the cause of a curious excess of gamma-ray light coming from the center of our galaxy.
Teachers are using Google+ to bring their classes behind the scenes at national laboratories and to teach students about careers in STEM.
Now that it looks like the hunt for the Higgs boson is over, particles of dark matter are at the top of the physics "Most Wanted" list. Dozens of experiments have been searching for them, but often come up with contradictory results.
Physicists operating an experiment located half a mile underground in Minnesota reported this weekend that they have found possible hints of dark-matter particles.
The search for dark matter runs deep with physicists Blas Cabrera and Bernard Sadoulet, who have chased this mystery far underground and will be recognized for their work as joint recipients of the 2013 W.K.H. Panofsky Prize in Experimental Particle Physics. The prize is named for SLAC's founding director, Wolfgang "Pief" Panofsky, and awarded by the American Physical Society.
