Epigenetic marks acquired from environmental exposures throughout life influence human health and may even transcend generations.

Whole-genome sequencing reveals a wide range of UV-induced DNA changes in human skin cells, and lighter skin collects more mutations, sometimes to “sky high” levels.

Their relocation explains horizontal genome transfer first described more than a decade ago.

Genetic evidence points to individuals from South America having possibly floated on a raft to Polynesian islands about 500 years before Europeans navigated there.

A modeling study counters initial interpretations that the cluster began with someone who flew to Seattle in mid-January.

In recent years, laboratories on the continent have ramped up genomic sequencing capabilities, offering in-country analyses rather than outsourcing the job.

The small number of genetic differences between the original strain of the novel coronavirus from Wuhan and those currently circulating in the US population indicates that a vaccine may likely offer lasting immunity.

Researchers find 380 amino acid substitutions between 2019-nCoV and severe acute respiratory syndrome (SARS)-related coronaviruses.

Researchers are trying to figure out where it came from, whether it’s evolving, and just how big a threat it will be.
