The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability, according to a new study by an ...

A planet's habitability is determined by a confluence of many factors. So far, our explorations of potentially habitable ...

Researchers grew crystals containing actinium and illuminated them with X-rays to learn how the radioactive metal binds with other elements. That information could help design better cancer treatments ...

In spring 1949, three prospectors armed with Geiger counters set out to hunt for treasure in the arid mountains of southern Nevada and southeastern California. In the previous century, those mountains ...

Nearly 80 years after scientists at Oak Ridge National Laboratory discovered an extremely rare radioactive element called promethium, a team at the lab published a landmark study on the subject that ...

The first-ever discovery of an extraterrestrial radioactive isotope on Earth has scientists rethinking the origins of the elements on our planet. The tiny traces of plutonium-244 were found in ocean ...

Polly Arnold is drawn to challenging problems at the far reaches of the periodic table. “It’s all about the f block,” she says of the work in her group, which is split between the University of ...

Element 99 — mysterious and exceptionally radioactive — sits inconspicuously in the bottom row of the periodic table. Named for legendary physicist Albert Einstein, einsteinium has been one of the ...

Sinclair International has begun human trials of a new anti-radiation drug called HOPO 14-1 that is designed to help decontaminate those who have been exposed to radioactive elements as a result of a ...

Researchers from Australian National University have discovered the first ever extraterrestrial radioactive isotope on Earth. The discovery is causing some to reconsider the origins of elements on ...
