The MiniBooNE experiment has detected far more electron neutrinos than predicted: a possible harbinger of a revolutionary new elementary particle called the sterile neutrino.
Trying to work out what dark energy really is (or if it even exists) requires accurate measurements, particularly of the rate at which the universe is expanding.
Few periods in history were shaped by science as much as the 1950s. The Cold War was in full swing. The space race was finishing its first lap with Sputnik's launch. The Manhattan Project remained fresh in everyone's minds.
When physicists organized the first Particles and Nuclei International Conference in 1963, nobody thought that the acronym PANIC could cause trouble in getting the word out about the meeting. That was before the now-common use of email.
The weak force is responsible for the decay of matter: unstable particles made of heavy quarks and antiquarks decay into particles made of their lighter cousins.
Students around the world are familiar with the periodic table of elements, a chart that outlines how protons, neutrons, and electrons form more than 100 different types of atoms.
If you are working on a PhD, chances are you're too busy feeding your brain to plan your next meal. Particle physicists share how they managed when they needed cheap or fast meals during grad school.
Although we now think of the universe as three bulky, nearly-flat dimensions, we might soon discover that the fabric of space-time consists of many more dimensions than we ever dreamed.
Stepping onto the site of a physics laboratory, you might expect to see enormous accelerators, ultra-powerful supercomputers, or scientists in lab coats racing between experiments. At one lab, however, what you will actually see are goats.
