How we discovered a glowing galactic ghoul

It's a classic Halloween tale. A group of ghost hunters visit a grand old house that is rumored to be haunted. But after thoroughly exploring, they leave disappointed: there are no ghosts to be seen. Only later, when looking ...

The hunt for hot nuclear matter

In particle physics, a jet is a shower of collimated particles generated by a highly energetic quark or gluon. In a lead-lead collision, jets must traverse through quark gluon plasma, altering their energy, track and consistency.

CERN lab on the hunt for dark matter

Europe's physics lab CERN on Tuesday said it was planning a new experiment to look for particles associated with dark matter which is believed to make up some 27 percent of the universe.

Neutron stars cast light on quark matter

Quark matter – an extremely dense phase of matter made up of subatomic particles called quarks – may exist at the heart of neutron stars. It can also be created for brief moments in particle colliders on Earth, such as ...

X-ray Rabi oscillations between nuclei observed in coupled cavities

X-rays interact weakly with matter. This is their greatest strength for many applications, but also a fundamental weakness for others. In particular the fields of nonlinear optics and quantum optics, mainstays for both fundamental ...

A carbon sink that can't be filled

Forests can store as much as 45 percent of the world's terrestrial carbon, making them a critical part of the process of regulating climate change.
