Underwater cave discovery leads to clues about early North Americans

A team of international scientists including Ed Reinhardt, Geography & Earth Sciences, have discovered an almost completely intact skeleton, that of an adolescent girl, in an underwater cave in Mexico. Their findings, published in Science and featured in numerous media outlets including The Globe and Mail, have yielded information about the genetic origins of early North Americans. Reinhardt and his team collected core samples from the pit and analyzed the sediment, microfossils and water chemistry changes over time, to reconstruct the flooding history of the cave system, and to determine the age of the 13,000 year old skeleton.

Life Sciences student breaking down mobility barriers

It’s a simple map to help people with mobility problems navigate campus, and an award winner. Created by Life Sciences student Nick Schoenhoff, the Campus Accessibility Mapping Project, or CAMP, rates the pedestrian pathways of McMaster using a green-yellow-red code, based on their condition, steepness and other factors. Schoenhoff’s creation was judged a runner-up award in the Innovative Designs for Accessibility or IdeA competition, of the Council of Ontario Universities. He’s now working on an electronic version with the capacity to add live updates for intermittent barriers such as snow.
