When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

Yale University has begun a multi-phase renovation of the former Wright Nuclear Structure Laboratory that will reinvent the landmark nuclear physics lab for a new era in physics research. Expected to ...

The inside of giant planets can reach pressures more than one million times the Earth's atmosphere. As a result of that intense pressure, materials can adopt unexpected structures and properties.
