Connection Between Epigenome, Selective Mutability, Evolution, and Human Disease
Li, Harris et al., PLoS Genetics
Researchers at the Baylor College of Medicine and elsewhere propose a "connection between the epigenome, selective mutability, evolution, and human disease" based on the findings of their study on associations of structural mutability with germline DNA methylation and with non-allelic homologous recombination mediated by low-copy repeats. "Combined evidence from four human sperm methylome maps, human genome evolution, structural polymorphisms in the human population, and previous genomic and disease studies consistently points to a strong association of germline hypomethylation and genomic instability," the Baylor-led team writes.

Set your TiVos. Tonight's NOVA scienceNOW, airing at 9pm Eastern, looks into personal genetic testing. The preview to the episode says Harvard's Steven Pinker took a genetic test that told him he had an 80 percent risk of being bald — Pinker's hair is a cross between Mozart and Einstein — and now he's part of the PGP that will be posting their DNA sequences on the Internet. If you can't catch it tonight and haven't succumbed to getting a digital recorder, you can watch the program tomorrow at PBS's website.
