Mixed-ancestry genetic research shows a bit of Native American DNA could reduce risk of Alzheimer’s disease

Using a technique called admixture mapping, researchers can leverage the diversity of people with mixed ancestry to look for hard-to-find genetic risk factors for diseases like Alzheimer’s disease.

Scientists are on a path to sequencing 1 million human genomes and use big data to unlock genetic secrets

The first full human genome was sequenced 20 years ago. Now, a project is underway to sequence 1 million genomes to better understand the complex relationship between genetics, diversity and disease.
