Digging up the dirt on a species eaten into extinction; botox - more than skin deep; a sweet solution for restoring woodlands; woman in love with crayfish!; radioactive beauty treatment! and wasps give ants a free ride.EATEN TO EXTINCTIONAround the world, archaeologists and palaeontologists hotly debate the cause of species extinctions. Were humans responsible for the disappearance of at least some species? Or, were they merely witness to extinctions caused by environmental changes or other natural events? On the small Pacific islands of Vanuatu, Dr Paul Willis reports on recently excavated evidence that sheds new light on these controversial questions. BOTOX FOR MIGRAINESAustralians receive close to a quarter of a million Botox injections each year! But in the process of removing worry lines from our faces, something unexpected has occurred. Some people discover they've been cured of a scourge that's afflicted them all their lives migraines. Jonica Newby examines the history of Botox as poison, beauty treatment and medicine.CRUSH ON CRUSTACEANSWhen Dr Susan Lawler joined La Trobe University, with a doctorate in evolutionary genetics from Washington University, she discovered that Victoria was a hot spot for crayfish. To her surprise she found that scientists had conducted very little research into these intriguing freshwater crustaceans. Almost two decades later, still fascinated by the creatures, she continues her self confessed 'romance'. She even keeps her favourite specimens as pets!SWEET SOLUTION FOR WOODLANDSThe wealth derived from Eastern Australia's grazing and crop farms has come at a price to both the natural environment and sustainable agriculture. Scientists in Albury Wodonga have found that a spoonful of sugar can provide a new insight in the battle to restore the original ecosystem. Tanya Ha took a stroll in the paddock to look at the grass roots research. RADIANT BEAUTYIn the 1920s, before much was known about the ill effects of radiation, some sought to enhance their beauty with treatments of radium.FREE FLIGHT FOR ANTSResearchers at the University of Wellington have captured some extraordinary behaviour of the common wasp Vespula vulgaris and the New Zealand native ant, Prolasius advenus. The invasive wasps prefer to give ant competitors a free flight rather than fight over the same food |
