Hello,
Sometime in the last 6 months I read that researchers analyzing data from the decay of a subatomic particle and reported that the decay appeared to be random or unpredictable. I recall they said this particular reaction was very low level. This would have been in either Science, Nature, Scientific American, or Science News. I have retired and access to them is difficult now.
Does anyone remember that publication?
I would like to learn more about this work and its significance. My typical search engine responses are too large to read in entirety and frustratingly full of junk. Any search suggestions would be appreciated.
Thank You,
Steve

As I recall some experiments had shown that the radioactive decay wasn't random but appeared to vary with the time of year. Other experiments ruled out any such variation to a reasonable confidence level...

Like you, I'm sure I've seen articles in the popular press on this subject but where?

RADIOACTIVE materials decay at a predictable rate—so predictable, in fact, that scientists widely use them to date artefacts and geological objects. That, at least, is the received wisdom, which Jere Jenkins and Ephraim Fischbach, from Purdue University in Indiana, think may need revising. In 2006 Dr Jenkins noticed that the decay rate of the radioactive isotope manganese-54 dipped 39 hours before a solar flare came crashing into Earth's protective magnetic field. Now it seems that the sun might affect other types of decay, too.

That result is utter, complete and total rubbish.

Fishbach has a habit of re-analyzing other people's data and making claims that the people who actually did the experiment would not make.
