Gene editing could eliminate mosquitoes, but is it a good idea?

Researchers have rendered a population of mosquitoes in a lab sterile using the gene-editing tool CRISPR-Cas9 by homing in on a specific target in insect DNA -- the doublesex gene -- raising the possibility of eradicating disease-carrying species of the insect entirely, according to a new study published Monday in Nature Biotechnology.

11,500-year-old infant remains reveal ancient population

The skeletons of two ancient infants, who lived and died in Alaska 11,500 years ago, are helping tell the story of a previously unknown population called the Ancient Beringians, according to a study published in the journal Nature on Wednesday. This is the first genomic evidence that all Native Americans can be traced back to the same population that migrated using a land bridge.
