Genomics

Driven by her fascination with highly repetitive, hard-to-read parts of our DNA, Karen Miga led a coalition of researchers to finish sequencing the human genome after almost two decades.

Scientists have reported large DNA structures in some archaea that defy easy categorization.

The discovery of a gene shared by two unrelated species of fish is the latest evidence that horizontal gene transfers occur surprisingly often in vertebrates.

In some symbiotic partnerships, an RNA-based mechanism may sabotage the growth of greedy hosts.

Transcription factors that act throughout the genome can arise from mashups of transposable elements inserted into established genes.

The bizarre genome of the world’s most mysterious flowering plants shows how far parasites will go in stealing, deleting and duplicating DNA.

A patchwork of genomic differences in the placenta may explain the organ’s “live fast, die young” strategy and its connections to cancer.

New research links serotonin and dopamine not just to addiction and depression, but to the ability to control genes.

Recent major surveys show that reductions in genomic complexity — including the loss of key genes — have successfully shaped the evolution of life throughout history.
