Scientists in Paris discovered two new substances with incredible radioactivity. It earned them the Nobel Prize in Physics ...

The analysis concluded that the decay heat from these radioactive elements could support the life activities of more than ...

Radioactive potassium, common enough on Earth to make potassium-rich bananas one of the “hottest” foods around, appears also to be a substantial source of heat in the Earth’s core, according to recent ...

How common are Earth-like planets in the universe? When I started working on supernova explosions, I never imagined that my ...

Scientists have revealed key properties of radioactive promethium, a rare earth element with poorly understood applications, using a groundbreaking new method. When you purchase through links on our ...

Stars, like the Sun, are remarkably constant. They vary in brightness by only 0.1 percent over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep ...

A strange radioactive 'blip' has been detected deep beneath the Pacific Ocean. Analyzing several thin layers of seafloor crust, scientists in Germany have identified a sudden surge in the radioactive ...

Bacteria can use certain radioactive elements to sustain their metabolism. A team led by LMU chemist Lena Daumann has demonstrated for the first time that bacteria can use certain radioactive elements ...

Radiometric dating, utilizing the predictable decay rates of radioactive isotopes within rocks and other materials, is the primary method for determining the age of geological samples. Multiple ...

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a ...

A remote outcrop in Canada harbors rocks that are at least 4.16 billion years old, researchers report June 26 in Science. If true, these rocks would be the oldest known on Earth and the first to date ...
