That is an interesting article. But it bothers me that qPCR is the only assay they used. I'd really like to see those microarrays they talked about, it's been over 5 years and they already had the RNA from the qPCR. Either someone didn't think it was worth funding, or they didn't find anything worth publishing. Also, calmodulin is involved. There are techniques to measure and visualize calmodulin activity. Showing that calmodulin-Ca++ binding actually increases in those timeframes would be much stronger evidence for their claim.
So, no I'm not quite going to fuck myself yet. Extraordinary claims require extraordinary evidence, and there's nothing extraordinary here.
