Science commentator Laurie Winkless joins Kathryn to talk about a big study that's looked at the scale of loss of elephant habitat in Asia. Over three centuries two thirds of suitable habitat - an area about the size of India - has been swallowed up by human land use. Glass bricks were all the rage in the 80s, but their thermal performance isn't very good. Now researchers have designed a new brick that can let light through while also acting as a form of thermal insulation. The trick? 'Frozen smoke'. And a global study led by researchers in Australia has found mosses growing on topsoil absorb massive quantities of carbon dioxide.
