Surfing scientist, Ruben Meerman learns how dolphins win the girls and Anja Taylor investigates the incidence of tree die-off in Western Australia.COMPUTER GAME ADDICTIONGiven the time that many kids and adolescents spend glued to a screen of some sort, many parents worry about their children becoming 'addicted' to computer games. With the advent of the internet, the possibility of being connected to such games and of being connected to other people playing them simultaneously has skyrocketed. Jonica Newby explores some of the most popular online games and discovers the pleasure and pain incentives that make them potentially so addictive. Who are most at risk and what can parents do to prevent their children becoming trapped in the game?DOLPHIN COURTINGIn the animal world males have evolved a huge variety of strategies to attract the ladies - some sing, others dance, some are handsome, while some others are just imposing. But in Port Stephens on the NSW coast, four dolphins, dubbed 'The Beatles', have formed an alliance to make them the most successful breeding males of the group. Surfing scientist, Ruben Meerman, encounters two of the fab-finned four, and learns how researchers have painstakingly worked to identify the dolphins and their offspring.TREE DEATHSAround the world trees of all species are dying off in big numbers. Is it climate change? Warmer temperatures amplify drought effects, weaken trees and reduce their defences, while at the same time increasing populations of tree pests. The number of documented episodes of tree loss related to warming and droughts has risen rapidly in recent years indicating that more trees are reaching their mortality thresholds. Anja Taylor investigates the incidence of tree die-off in Perth and the South West of Western Australia where forests of Jarrah, Marri, Tuart and Banksias are under attack from pests and diseases Event Broadcast 2012-04-26 at 20:00:00 Notes Classification: G Subject Computer games -- Social aspects.
