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 ...

New research has enhanced scientists' understanding of how free neutrons decay into other particles. The work provides the first measurement of the energy spectrum of the photons that are released in ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

This story is from the Aug. 23, 2010 issue of Stanford Report. When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a ...
