There is a news column in Science that talks about soon-to-be-published results from the group at LUNA in Italy.
http://www.sciencemag.org/cgi/content/full/304/5675/1226b
Their results suggest that the current model for the CNO cycle (carbon-nitrogen-oxygen) was flawed and the calculated rates were about twice too high. This suggests that the oldest stars we have observed are older than 14 billion years.
Yet, the data from WMAP has allowed folks to calculate the age of the universe at 13.7 billion years, with an accuracy or +/- 1%.
Will someone please give us an explanation?
