PLOS Genetics, a team from Drexel University, the University of California, San Francisco, and Old Dominium University take a look at
sub-telomeric sequence diversity in individuals from dozens of human populations. Using high-throughput, single DNA molecule optical mapping with a nanochannel array-based approach, the investigators assessed sub-telomeric variants, including structural alterations, in genome sequences for 154 individuals from 26 populations.
