Genomics

The first animal genus defined purely by genetic characters represents a new era for the sorting and naming of animals.

With a fully sequenced genome in hand, scientists hope they are finally poised to learn how axolotls regenerate lost body parts.

The more closely geneticists look at complex traits and diseases, the harder it gets to find active genes that don’t play some part in them.

An ambitious study in yeast shows that the health of cells depends on the highly intertwined effects of many genes, few of which can be deleted together without consequence.

The computer scientist Barbara Engelhardt develops machine-learning models and methods to scour human genomes for the elusive causes and mechanisms of disease.

For the first time, researchers see how proteins grab loops of DNA and bundle them for cell division. The discovery also hints at how the genome folds to regulate gene expression.

Two new papers urge caution in using powerful genome-editing technology against invasive species: Models show that aggressive gene drives can’t be contained in the wild.

Elephants did not evolve to become huge animals until after they turned a bit of genetic junk into a unique defense against inevitable tumors.

How many Neanderthals were there? Archaeology and genetics have given very different answers. A new study reconciles them and reveals the lost history of these ancient people — including an early brush with extinction.
