Defending the flying fox; how safe is the air inside our homes?; E=mc2 - an equation for weight loss?; unravelling the mysteries of where Emperor Penguins go when they leave home.IN DEFENCE OF THE FLYING FOXFlying foxes are vilified for their behaviour, such as feasting on fruit orchards and trees in our Botanic Gardens, as well as being carriers of the rare but deadly Hendra virus. But, how much do we really know about these fruit bats?In Melbourne and Sydney, the Royal Botanic Gardens face large scale destruction by many thousand strong colonies of bats. They're tearing the trees apart. Some say the bats must move because they are destroying valuable and rare trees, while others say that they are simply part of urban wildlife and we have to learn to co-exist with them. But for garden managers, it's reached crisis point. Paul Willis looks at why these much maligned creatures are appearing more in our urban environments and what measures are being taken to safely relocate them out of the Botanic Gardens.INDOOR AIRWhen we think of air pollution, images of billowing smokestacks or other industrial outpourings most commonly spring to mind. But perhaps we should be focusing a little closer to home, in fact inside our homes! Air quality in the outdoor environment is thoroughly researched and regulated, but little is known about the air inside our homes. Tanya Ha investigates a new indoor air quality survey conducted by CSIRO of 40 households in Melbourne.THE E=MC2 DIETIt's the most famous equation in physics...E=mc2. But you don't hear it discussed in relation to weight loss - at least not until Bernie Hobbs puts her unique spin on it.EMPEROR PENGUINSRight now, in the depths of a harsh Antarctic winter, Emperor Penguin eggs are hatching. At temperatures of 40 degrees below zero, Emperor Penguins breed in the coldest environment of any bird species. While in Antarctica, Mark Horstman met a seabird ecologist who has spent decades unravelling the mysteries of where Happy Feet goes when he - or she - leaves home |
