Nebraska has been a "red state" for decades, but Nebraska state senator Joel Johnson, a Republican and former surgeon, was bothered by Senate colleagues' attempts in recent years to pass a bill banning somatic-cell nuclear transfer (SCNT).

Researchers at deCODE Genetics in Reykjavik, Iceland, have discovered a large chromosomal rearrangement in the human genome that appears to have been selected for in some European populations.1The rearrangement, a 900-kilobase inversion polymorphism at chromosome 17q21.31, appears in two lineages, H1 and H2, that have diverged for as many as 3 million years with no evidence of having recombined. The H2 lineage – rare in Africans, almost nonexistent in East Asians, but found in 20% of Europ
