Graham Phillips looks at what ancient teeth reveal about our dental health and Ruben Meerman sounds out who is really doing the composing - musician or machine.SOUTHERN SURVEYORFor a nation girt by sea, with the world's third largest Exclusive Economic Zone, Australia has a surprisingly small blue-water science fleet. Based in Hobart, the hard-working Southern Surveyor is Australia's only national marine research vessel. For more than two decades, this converted trawler has criss-crossed an eighth of the planet's surface, from the Indian to the Pacific oceans, Macquarie Island to the Philippines. Mark Horstman meets the ship herself, and the scientists who depend on her for their research. We discover the advances in science made possible by the ship, and the highlights of the last twenty years. Join Catalyst aboard as the Southern Surveyor embarks on her last science voyage.ANCIENT TEETHHuman health relies on a delicate balance between the microbes that live in us and on us. But, we know very little about what the thousands of bacterium, fungi and viruses, collectively referred to as the 'human microbiome' do in our body. We know even less about how the human microbiome has changed over our evolution. Some clues may reside in tartar found on ancient teeth. Australian researchers have extracted ancient DNA from pre-historic skulls, and created the world's first time line of the bacteria living in our mouths over thousands of years. They discovered that modern diets have left the human mouth in a 'diseased state', when compared to the relatively healthy gums and teeth of our ancestors. Graham Phillips looks at what ancient teeth reveal about our dental health.FUTURE MUSICFor hundreds of years music has been visualised as dots on a page. More recently, tunes were transformed into a visible soundwave. Now a new interactive technology, developed by Australian scientists, is allowing musicians to see their compositions through a new platform and change their beats in real time. Ruben Meerman sounds out who is really doing the composing - musician or machine |
