Torrential rain and muddy roads are not  enough to deter a young Kununurra man  in his bid to run in one of the world’s most  famous footraces, the New York Marathon. Joseph Davies, who fi nished Year 12 at  Kununurra District High School last year,  has just returned home from selection trials  in Alice Springs, where he was coached  by Australian running legend Robert de  Castella, a four-time Olympian and two-time  Commonwealth Games gold medallist. Davies, 18, was one of 12 hand-picked  Indigenous hopefuls who attended the Alice  Springs selection trials. If selected in the fi nal six-person squad,  he will travel to the Australian Institute of  Sport in Canberra for more training before fl ying to the US to compete in the marathon  in November. De Castella said the squad , the brainchild of  his not-for-profi t organisation, SmartStart,  was the fi rst step in establishing a program  to develop Indigenous long-distance runners  in Australia. Davies, who is training daily, even in wet  season downpours, said he understood  training for the marathon would not be easy,  but it was a challenge he was ready for. ‘I know it’s a once in a lifetime opportunity  and I really hope I get selected,’ he said. The northern hemisphere cold will drive him  to ‘just run faster’. Nathan Dyer The West Australian 15 January 2010 In May 2009, scientists unexpectedly fi lmed an eruption of the deepest submarine volcano yet discovered. This volcano, West Mata, lies south-west of Samoa in the Pacifi c Ocean. Scientists had found volcanic debris in water samples close to West Mata in November 2008. This meant that the volcano was active and might erupt again at any time. During the 2009 mission, a submersible robot (Jason) was lowered about 1200 metres to West Mata’s summit. Jason was carrying cameras to fi lm the volcano, when suddenly the volcano erupted. Through Jason’s ‘eyes’, the scientists were able to witness a submarine eruption close-up for the fi rst time. Fiery bubbles of molten lava shot up into the ocean – a spectacle described by the scientists as ‘underwater fi reworks’. Figure 1 A cloud of sulfur and molten lava erupts from West Mata. On land, a robot like Jason could not have moved so close to an eruption. The force and the heat of the lava would have destroyed the robot and its cameras. The high water pressure in the deep sea reduced the violence of West Mata’s explosion. The icy seawater quickly cooled down the exploding lava bubbles, turning them to black rock that sank to the ocean fl oor. Scientists hope that the detailed images Jason took will give further insight into the formation of submarine volcanoes. Figure 2 Jason’s robotic arm collects samples during the eruption.

Salinity is one of Australia’s greatest environmental problems. It occurs when too much salt rises from under the ground to the surface and ruins the soil. In 2000, there were 2.5 million hectares of salt-affected land in Australia. This may increase to 17 million hectares by 2050. Rising watertable Land clearing is the major cause of Australia’s dryland salinity problem. Trees act as pumps, removing water from the soil and keeping the water level in the ground well below the surface. This level is called the watertable. Water absorbed by the roots travels through the trunk and out through the leaves into the air. In a day, over 700 litres of water may pass through the leaves of a fully grown river red gum. Beneath the ground across much of Australia there are large deposits of salt laid down by ancient seas. The salt is harmless underground, but when it comes to the surface it does damage. When trees are removed the watertable rises, bringing the salt with it. Costs The cost of salinity to Australia’s farming production is over $250 million a year, and the cost is increasing. The CSIRO estimates that salinity will cause the extinction of 1000 species of Australian plants and animals. Salinity also damages water pipes, roads, houses and parks. In the city of Wagga Wagga, this type of damage costs over $3 million each year. The level of salt in the Murray River is also increasing, and by 2020 the water in Adelaide piped from the Murray may be too salty to drink. Halting the salt Replanting native trees is a very effective method of lowering the watertable. Native grasses have long roots that prevent water from rising to the surface, unlike many introduced grasses that have shallow roots. Slow change For many years, the practices that led to today’s salinity problems went on without anyone knowing the consequences. This was because the effects of land clearing on watertables were not immediately obvious. Similarly, the effects of changing these practices will not become noticeable for decades, because it will take that long for seedlings planted now to become trees and restore watertables to their natural levels. Trees draw water from the soil keeping the watertable low. watertable R ain soaks into the soil. W ater transpires (is emitted as water vapour) through leaves.

Mort is cooking a meal of fi sh for the Ranger. Mort’s dog Blue is close by, as  usual. The Ranger grinned. ‘Don’t trust me, do you?’     ‘Trusts you more than most,’ Mort declared, turning the fi  sh. ‘A man’d  think he knew every word you said.’     ‘Course he does,’  said the Ranger roundly. ‘Most of  ’em, anyhow. He  knows a lot more of what you say than you know of what he says, mate.’     ‘Why don’t you shift that paper off the table and make a bit of room?  Instead of telling a man about his own dog?’     ‘All right, all right,’  said the Ranger, bundling the newspaper off the  table, ‘but most people don’t have a clue how an animal’s talking to them,  and understanding them. Body language, it’s called. You talk the same  way and don’t know you’re doing it, but Blue can read it all right.’     ‘That,’  said Mort, dismissing body language and setting up the fi  sh.  ‘Yeah, I’ve heard about that. Only I’m a poor ignorant coot, and I just talk  words. Pull up a chair, will you, before this fi  sh gets cold.’     ‘Words too,’  said the Ranger, sitting down. ‘Man, this smells good to  a hungry bloke. You’re a life-saver.’ He broke off the tail of the fi  sh and  passed it to Blue, who took it neatly and thumped his own thick brush on  the fl  oor again. ‘How many words do you reckon your dog knows?’     Mort considered, settling into a chair by the stove. ‘More than a man  realises, I reckon,’  he admitted. ‘There’s “sit”, of course. And “stay”. And  “lie down and shut up”. There is “wait” and “come here”. He’s not a  working dog, of course, or there’d be more.’     ‘All right,’  said the Ranger argumentatively. ‘That’ll do. Now, how did  you teach him those words, eh?’     ‘The way anyone does, I reckon.’     ‘How?’ insisted the Ranger between mouthfuls of fi  sh. ‘Did you belt  them into him?’     ‘Eh? No, I didn’t.’     ‘How, then? Did you go through some routine like breaking in a horse?’     ‘No, you drongo, I didn’t have to. A man just says them often enough.’     ‘Right!’ shouted the Ranger, triumphant. ‘You just said them and he  learnt them! So why should he learn the words you want him to learn and  not any of the others? Hm? He’s only got to hear ’em often enough, you  just said. Is he supposed to say to himself, “I’m not supposed to learn that  word, so I won’t.” Hm?’ Mort’s dog Blue Where on Earth are you? Twenty years ago the Global Positioning System (GPS) was for the use of military personnel only, a network of orbiting satellites designed to guide missiles and pilotless drones anywhere on the planet to the accuracy of a metre. Today, it’s on car dashboards, virtually all new mobile phones and personal computers. Nearly a million satellite navigation devices have been sold in Australia alone. In 2000, United States President Bill Clinton switched off the system’s “selective” control by the military, releasing it for commercial purposes. However, it took some time for the wider potential of GPS to be realised. Now it’s popping up on so many devices that privacy concerns are being raised. Some mobile phones can show you the nearest supermarket, hotel or dry cleaner. Some Internet services act like a beacon, showing friends – and potentially anyone else using the application – where you are at a particular time. Some retailers offer smart-phone applications that can tell users the location of their nearest store, wherever they might be at that time. But that’s just the fi rst step. Marketers are particularly excited about being able to target advertisements at particular consumers based on their geographic location. Imagine fi nding an advertisement on your phone from a retailer offering $10 off your favourite brand of T-shirt as you’re walking past their store. A handy service? Probably – but privacy advocates worry that location-based services are ripe for abuse by companies. And then there are the risks for personal security. A robber could know precisely when a person is withdrawing money from a bank or a burglar could work out when to break into people’s homes. Those scenarios may seem far-fetched, but the epidemic of identity theft and security breaches in recent years should raise some concerns about how well marketers will protect location information. 6

Some mobile phones can show you the nearest supermarket, hotel or dry cleaner. Some Internet services act like a beacon, showing friends – and potentially anyone else using the application – where you are at a particular time. Some retailers offer smart-phone applications that can tell users the location of their nearest store, wherever they might be at that time. But that’s just the fi rst step. Marketers are particularly excited about being able to target advertisements at particular consumers based on their geographic location. Imagine fi nding an advertisement on your phone from a retailer offering $10 off your favourite brand of T-shirt as you’re walking past their store. A handy service? Probably – but privacy advocates worry that location-based services are ripe for abuse by companies. And then there are the risks for personal security. A robber could know precisely when a person is withdrawing money from a bank or a burglar could work out when to break into people’s homes. Those scenarios may seem far-fetched, but the epidemic of identity theft and security breaches in recent years should raise some concerns about how well marketers will protect location information. 7

Snowboarding is fast becoming one of the most popular winter sports in Australia. Australian athletes have been amongst the world’s top snowboarders since Zeke Steggall represented Australia in the fi rst Olympic snowboarding event in Japan in 1998. Nathan Johnstone was number two in the world in 2008 and 2009, and Torah Bright won a gold medal in snowboarding at the 2010 Winter Olympics. Snowboarding in Australia 12
