Vive La Différence Iii

We show that, consistently, there is an ultrafilter F on ω such that if N n = (P l n ∪ Q l n, P l n, Q l n, R l n) (for l = 1, 2, n < ω), P l n ∪ Qn ⊆ ω, and Q

Vive la différence II. The Ax-Kochen isomorphism theorem

We show in §1 that the Ax-Kochen isomorphism theorem [AK] requires the continuum hypothesis. Most of the applications of this theorem are insensitive to set theoretic considerations. (A probable exception is the work of Moloney [Mo].) In §2 we give an unrelated result on cuts in models of Peano arithmetic which answers a question on the ideal structure of countable ultraproducts of Z posed in [...

In vitro evolution experiments reveal that single mutations in three genes can increase the ability of E. coli to survive ionizing radiation by a factor of 1000.
