TITLE: Mathematical research papers in general science journals
QUESTION [25 upvotes]: I am interested in collecting a list of research papers with a mainly mathematical focus that appeared in high-reputation general science journals without a dedicated mathematics section. This would include things like Nature or Science, but exlcude, for example, PNAS.
By a "papers with a mainly mathematical focus" I mean publications whose purpose is the announcement/description/proof of a new mathematical method or result, rather than the mere use of (sophisticated) mathematical techniques to solve a scientific problem from another discipline. 
I would imagine that often such papers are complemented by a publication in a more traditional mathematical venue that expands on technical details maybe omitted in the general science journal, and it would be nice to collect those as well to see how the two publications differ from each other.
I vaguely remember coming across one or two of such papers in the past, but I cannot find them anymore and cannot, therefore, give an example of what I am looking for.
I would be grateful if someone could convert this question to Community Wiki mode, I seem to be unable to find the right check-box.

REPLY [3 votes]: Evans function and Fredholm determinants by Issa Karambal, Simon J. A. Malham is in Proc. R. Soc. A., February 2015 Volume: 471 Issue: 2174.
Proceedings of the Royal Society A does not have a dedicated mathematics section. It features plenty of applied mathematics papers and mathematical physics papers of course, but interestingly, sometimes also pure research mathematics.
