What if there was another nuclear incident in the US? A disaster management scholar looks back at the history of nuclear events to assess the risk.

Duckweed is the perfect space food: small, fast-growing and nutritious. By studying how light levels changed the production of radiation-fighting antioxidants, researchers made it even better.

Seventy-five years after the first nuclear detonation and nearly 30 years since testing was banned, the US is considering resuming live nuclear testing.

Radiation from space may have left a mark on early life, researchers say. It could explain chirality, or why molecules have left- and right-handed versions.

A new polymer composite may offer a lighter, non-toxic radiation shielding to replace lead, researchers report.

A new material allows for better monitoring of X-ray radiation, researchers report. That could give a boost to medical imaging or even airport security.

A new algorithm could speed up detection of weapons-grade nuclear material at national borders to protect against nuclear terrorism, researchers report.

In my ten years working with and researching it, I've encountered lots of myths.

Researchers have shown light and sound could replace radiation to image the heart. They say the method has potential for other procedures as well.

A new method can turn bricks into 3D "cameras" to help find clues in the hunt for weapons-grade nuclear materials.
