Hypothetical scenario: A nuclear bomb is detonated in one of America’s most populated cities. Just as at a crime scene, the officials need to find the culprit.

The University of Adelaide today officially opened its new $100 million science and research building, The Braggs, named after two of its greatest alumni, 1915 Nobel Laureates Sir William Henry Bragg and his son, Sir William Lawrence Bragg.

An international team of astronomers has found that a nearby star previously thought to host two or three planets is in fact orbited by six or seven worlds, including an unprecedented three to five “super-Earths” in its habitable zone, where conditions could be right for life.

Using clouds of ultra-cold atoms and a pair of lasers operating at optical wavelengths, researchers have reached a quantum network milestone: entangling light with an optical atomic coherence composed of interacting atoms in two different states. The development could help pave the way for functional, multi-node quantum networks.

University of Adelaide researchers are developing a new type of laser system that will monitor methane, the main component of natural gas, levels across large areas. This will provide a useful tool for monitoring greenhouse gas emissions.

For decades, electronic devices have been getting smaller, and smaller, and smaller. It’s now possible—even routine—to place millions of transistors on a single silicon chip. But transistors based on semiconductors can only get so small.

It's not reruns of "The Jetsons", but researchers working at the National Institute of Standards and Technology (NIST) have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture—cathodoluminescence—to image nanoscale features.

Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole. This proposal, which endows dark matter particles with a rare form of electromagnetism, has been strengthened by a detailed analysis performed by a pair of theoretical physicists at Vanderbilt University.
