Researchers at UChicago Medicine found that a slight increase in walking cadence led to meaningful improvements in physical function for older adults who were frail or at risk of becoming frail. They also developed and tested an app to help measure walking pace more accurately.

A new Simon Fraser University-led study reveals interbreeding between humans and their ancient cousins, Neanderthals, as the likely origin of a neurological condition estimated to impact up to one per cent of people today.

The study, published this week in the journal Evolution, Medicine, and Public Health, was led by Kimberly Plomp, a recent postdoctoral fellow at SFU and Mark Collard, the Canada Research Chair in Human Evolutionary Studies and a professor in the Department of Archaeology. Their findings suggest that Chiari Malformation Type 1, a serious and sometimes fatal neurological condition, may be linked to Neanderthal genes that entered the human gene pool through interbreeding tens of thousands of years ago.
