Data from one of the first genome-wide association studies (GWAS), which focused on Parkinson’s diseases and was funded in part by The Michael J. Fox Foundation for Parkinson’s Research (MJFF), is now being made available to researchers through the National Human Genome Research Institute (NHGRI) and the National Center for Biotechnology […]

Papers published in Nature and Science this week support the previously held theory that humans originated in East Africa, migrating outward until they reached all parts of the globe. But the genetic work from these studies brings a new level of precision to human migration studies, with each group finding subtle and intriguing details that shed light on different aspects of […]

Our early human ancestors originated from a hot, humid climate where natural selection focused on dispersing heat. As humans migrated to colder climates there would have been evolutionary pressure to adapt to their new settings by boosting the processes that produce and retain heat.
Genes involved in energy metabolism are therefore likely to be central to heat and cold […]
