There hypothesis is that solar neutrinos are affecting radioactive decay on Earth. But why rule out a more general phenomenon that affects both nuclear processes in the sun and on Earth simultaneously ...

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 ...

What is your opinion on those results? I can't find many studies. The most important paper seem to be this. The reported variability is quite big, I would think that it would be quite easy to set up a ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

Working at a nuclear research centre as I do, I found Justin Mullins’s article on seasonal variations in radioactive decay most intriguing (27 June, p 42). The most dramatic change in radioactive ...

For half a century, our view of the world has been based on the standard model of particle physics. However, this view has been challenged by theories 1 that can overcome some of the limitations 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 ...

Certain isotopes such as Indium-115 (In-115) are extremely long lived, taking over 100 trillon years for half of the Indium atoms to decay away. These isotopes allow scientists to probe the precise ...
