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 ...
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 ...
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 ...
Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest (OK, maybe the coolest) is using radioactive ...
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 ...
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 ...
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 ...
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 ...
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 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 ...
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 ...
