Radioactivity, discovered more than 100 years ago and studied by physicists ever since, would seem to be a relatively closed subject in science. However, since the 1960s, the pursuit of at least one ...

Some claim that Earth is only 6,000 years old. But can physics actually support that idea. Radioactive decay, heat flow, starlight travel time, and orbital mechanics all place strict limits on Earth’s ...

Solar activity: does the Sun affect radioactive decay? Image of a solar flare taken in 2014 by NASA's Solar Dynamics Observatory spacecraft. (Courtesy: NASA/SDO) A new study of the radioactive decay ...

Researchers refute the assumption that the decay rate of some radioactive nuclides depends on the distance between the Earth and the Sun. PTB researchers refute the assumption that the decay rate of ...

Let's talk Einstein and Nuclear Physics. What does E=MC2 actually mean? Why is it useful? It's time for our second to final Physics episode. So, let's talk Einstein and Nuclear Physics. What does ...

WEST LAFAYETTE, Ind. - Researchers may have discovered a new method to predict solar flares more than a day before they occur, providing advance warning to help protect satellites, power grids and ...

The study of archaeology has long been carried out using tools from the physics lab. Among these are carbon-14 dating, thermoluminescence dating, x-ray photography, x-ray fluorescence elemental ...

Anomalies in the radioactive decay of beryllium-8 and helium-4 point to the existence of a new force of nature. That is the conclusion of a group of theorists in the US, who have scrutinized data from ...
