Clouds form when water vapour condenses onto tiny airborne particles known as aerosols. Once these particles grow larger than about 50 nanometres, they can act as cloud condensation nuclei, or CCN, on which cloud droplets form. Increased aerosol…

Supersymmetry plays a prominent role in the landscape of models that push beyond the Standard Model. Higgsinos, the supersymmetric partners of the Higgs boson, may help in addressing a number of unsolved puzzles, particularly if their masses are…

For John Ellis, the history of the Higgs boson is not a neat, short story that begins with a theory paper and ends with a discovery announcement. It is a long intellectual adventure, beginning in superconductivity, moving through the construction of…

A new state of matter Colliding heavy ions, such as lead, at nearly the speed of light in the LHC allows the creation of a new state of matter called the quark-gluon plasma (QGP). This near-perfect liquid of quarks and gluons is created because the…
