Nuclear and mitochondrial genome sequences from 120,000-year-old Neanderthal remains from Germany and Belgium revealed genetic ties to more recent Neanderthal populations.
Based on sequences for hundreds of E. coli ST131 lineage isolates, researchers propose a model that involves negative frequency-dependent selection on accessory parts of the genome.
To understand the evolution of brain conditions and other traits, investigators plan to sequence human and pathogen DNA in thousands of samples from Europe.
Using genome sequences for 161 present-day Papuans and Island Southeast Asians, researchers described three Denisovan lineages and estimated divergence times between them.
Molecular features in primary and recurrent glioblastomas indicated that key initiator mutations turned up years before diagnosis, often persisting in recurrent tumors.
