Among the many science toys that have fallen out of fashion since we started getting nervous around things like mercury, ...

Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

For the first time, researchers have directly observed an exotic type of radioactive decay called two-neutrino double electron capture. The decay, seen in xenon-124 atoms, happens so sparingly that it ...

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue explores how isotopes of carbon can be used to determine the age of once-living matter. Learn ...

The questions in this quiz are suitable for GCSE physics students studying stable nuclei, nuclear radiation, half life and nuclear equations. If you struggled with the quiz, don't panic - we've got ...

The Sun is changing the supposedly constant rates of decay of radioactive elements, and we have absolutely no idea why. But an entirely unknown particle could be behind it. Plus, this discovery could ...

About 50% of the heat given off by the Earth is generated by the radioactive decay of elements such as uranium and thorium, and their decay products. That is the conclusion of an international team of ...

A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed ...

Radioactive elements on Earth are like geological watches. A radioactive isotope of carbon is used to date human civilizations, among other things, because we know that its half-life is precisely ...

The European Space Agency’s (ESA) INTEGRAL space observatory has made the first direct detection of radioactive titanium associated with supernova remnant 1987A. The radioactive decay likely has been ...

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...
