It would seem that if this is found to be a true phenomenon then the situation gets even worse for YECs because increased activity in the sun appears to be slowing down the decay rate slightly.

Isn't the sun slightly further away in winter?
At least it's at a lower angle to the horizon such that we don't get as much heat (and presumably less of whatever particles are hypothesized to cause this effect) from it Edited by PurpleYouko, : No reason given.

When I first read of this i thought it was crap too. Just another set of bogus data reported in some half assed newspaper article.
But after doing a little more research I began to realize that the effect has been reproduced and very well documented in many well respected labs around the world. It is largely accepted as a proven fact that this effect actually does happen. If you haven't read about it yourself, this is as good a place as any to start http://www.sciencedaily.com/...ases/2012/08/120813155718.htm quote:

There doesn't seem to be a lot of research by other labs so far but here a few that I uncovered. The effect was reported in the news pages at the Stanford university web site and Purdue University website (as you are probably well aware) but I don't have access to the string of papers that were apparently published a few years back. A paper entitled "Additional experimental evidence for a solar influence on nu quote: The paper also introduces a fourth set of data from The Ohio State University Research reactor quote: Jenkins also collaborated with the GSI (Geological Survey of Israel) to publish this paperhttp://arxiv.org/pdf/1205.0205v1.pdf Ok so it isn't "dozens" of labs. If i said that then I withdraw the comment. That's 6 independent sets of data corroborating the possible effect and one attempting to debunk it. One thing I would like to note here is that the data that that Berkeley used in their rebuttal was collected only once per day over the period. This is arguably not a good enough time resolution to see the effect accurately. I'm not saying they did it wrong, just that in the Ohio state paper they specifically noted that their data was collected over a four hour period each day. quote:

Did I say many labs confirmed the predictive qualities of this data? If I did then that was not my intent. All I ever meant to say was that many labs had confirmed that the effect does indeed happen. Al I know about the predictive qualities of this is that researchers from Purdue have patented the concept of using decay fluctuations to predict solar flairs.
I shouldn't need to make that argument since the quote in my previous post spells it out. The point they make is that some solar flare events are only a few hours in duration so a resolution of one data point per day (not a single measurement presumably but several combined to a mean value. At least I hope that's what they mean) is not going to see such an event happen. Their experiment just has a very low resolution so says nothing of short term fluctuations. Surely you can't argue with the logic of that. It makes sense to me anyway. Edited by PurpleYouko, : forgot to address part of the post first time around

Certainly when looked at simply as a test of annual variation, the number of sample points taken per day is only relevant in terms of the premise that more data points is better than less data points.
The only interpretation you can make here is the correct one. I spoke (typed) too damn quickly without reviewing my data properly. If I had bothered to dig a little deeper before posting I would have discovered that the reasonably well accepted fact was that there is fluctuation of a cyclic nature and not that other labs had been able to predict solar flares. *presents wrists for a good slapping*

I also call bullshit.
I've been working with LASER ablation techniques in Mass Spectrometry for almost 20 years and this is the first time I have ever heard anybody spout such a load of rubbish about it. LASERs ablate material by heating it to the point of vaporization whereupon it rapidly expands into the cooler gas surrounding the point of ablation. LASER Desoprtion is a technique used to directly ionize organic materials for introduction into a mass spectrometer. Different compounds accept different charges (some + and some -) when hit with a LASER. This is pretty well understood and is used to the analyst's advantage by only taking the negatively charged components into the mass spec while rejecting unwanted positively charged components. (can be reversed in some cases) There is no pulling involved. It is more like an explosion. The sum of positively and negatively charged ions coming from an ablation event are pretty much equal to the overall initial charge of the object being ablated. There will be a certain amount of loss though. Some electrons or protons may be lost or gained in interactions with the local environment. quote: All the LASER supplies is heat.
