The long search for observational evidence of the sources of a particularly puzzling class of gamma-ray bursts has at last borne fruit. The new evidence suggests that short-duration GRBs are caused by mergers of neutron stars and black holes.

Exact solutions are prized because they can be used to compare theory with simulation and experiment without ambiguity. Finding them has sometimes proved arduous.

What will it take for devastated Gulf Coast universities to get back on their feet?

Scientists working in the US State and Defense departments are championing a program intended to reconnect the once-vibrant Iraqi science community with researchers around the globe.

Science sets itself apart from other paths to truth by recognizing that even its greate practitioners sometimes err.

By using the tools of physics in their teaching, instructors can move students from mindless memorization to understanding and appreciation.

Superconducting circuits can behave like atoms making transitions between two levels. Such circuits can test quantum mechanics at macroscopic scales and be used to conduct atomic-physics experiments on a silicon chip.
