Emerging research suggests that human attention spans are getting shorter. That’s a problem for people who want to make change in a world in which the issues we’re facing are growing ever more complicated. So now, perhaps more than ever, it’s important to understand the art and science of giving a good speech — and few people in Canada do that better than David Shepherd. But Shepherd says none of this came naturally to him. -

We follow Utah State University scientist and UPR reporter Ryan Helcoski and UMP student Mirandah Mnisi as they scope out a fresh kill. -
This week, Ryan Helcoski explores how carcass sites may become attractive to grazing herbivores as their nutrients aid in plant growth. -
In late November, Ryan Helcoski and his team search for an elephant carcass in South Africa, and detail what a carcass site search and recording looks like. -
Elephants in South Africa repeatedly visit the carcasses of other elephants and move the bones around. Researchers at Kruger National Park are working to understand this mysterious behavior. -
