nt.number theory - Infinitely many prime numbers of the form n2k+1?

It took me a while to find this: http://www.pnas.org/content/94/4/1054.full



Anyway by Friedlander and Iwaniec (1997). They proved that there are infinitely many primes of the form x2+y4. They mention near the end that they do not have a proof for primes of the form x2+y6 but would like one. So there is a way to go to settle x2+1.



FYI, what I did (not remembering title, authors, anything but the result) was write a program to give the primes x2+y4 and put the first dozen in Sloane's sequence site search feature.
