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 ...

Nuclear weapons tests are among the most violent events humans can trigger, and that violence leaves fingerprints in the ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Physicists have completed a new round of searches for the answer to why matter dominates over antimatter. But the radioactive decay that would solve the puzzle is evading them. It felt like the Apollo ...

The Standard Model of physics, which explains the properties and interactions of the fundamental particles, does a phenomenal job with the things it gets right, and there's nothing that it obviously ...

All the matter we know of in our Universe is made of both fundamental and composite particles. However, only a few of the fundamental particles are observed to be stable and not to decay into other ...
