Life on land depends on plants. And every plant balances opening its pores to let in carbon dioxide for photosynthesis; and closing its pores to retain water.
Graham Farquhar’s work has transformed our understanding of photosynthesis.
His models of plant biophysics have been used to understand cells, whole plants, whole forests, and to create new water-efficient wheat varieties.
Polymers are being used for non-stick coatings, anti-fouling technology, precision drug delivery, medical diagnosis, imaging, and many other applications.
Associate Professor Cyrille Boyer’s ideas are built on the revolutionary RAFT techniques (a technique to precisely control how small molecules are linked together to form large polymer chains) for which Professor David Solomon and Dr Ezio Rizzardo received the 2011 Prime Minister’s Prize for Science. His latest technology uses light and chlorophyll to catalyse the production of polymers.
Two science teachers from New South Wales and Queensland are using fresh approaches to get kids interested in science – and keep them interested.
Graeme Jameson’s technologies use trillions of bubbles to add billions of dollars to the value of Australia’s mineral and energy industries.
Graeme took flotation, a century-old technology developed in Broken Hill, and transformed it. A turbulent cloud of minute bubbles are pushed through a slurry of ground-up ore where they pick up tiny mineral particles and carry them to the surface.
Jane Elith is one of the most influential environmental scientists in the world, though she rarely ventures into the field.
She develops and assesses species distribution models, which are used by governments, land and catchment managers and conservationists around the world—in short, for applying the lessons of ecology.
Genes are not enough to explain the difference between a skin cell and a stem cell, a leaf cell and a root cell, or the complexity of the human brain. Genes don’t explain the subtle ways in which your parents’ environment before you were conceived might affect your offspring.
Another layer of complexity—the epigenome— is at work determining when and where genes are turned on and off.
Ryan Lister is unravelling this complexity. He’s created ways of mapping the millions of molecular markers of where genes have been switched on or off, has made the first maps of these markers in plants and humans, and has revealed key differences between the markers in cells with different fates.
Many teachers struggle to make science fun for their students. For a Canberra teacher, this means creating an environment where every student can see the impact of science in daily life. And an Adelaide teacher is keeping kids engaged by teaching science in Japanese.
Geoff McNamara from Melrose High School in Canberra has created a hothouse of science learning—complete with a seismometer, GPS antenna and weather station, each transmitting real-time data straight into the classroom.
“We all need science literacy to navigate the complexity of the modern world,” says Geoff. So he reaches out to each student’s interests— from genetics to driving to cosmology— to demonstrate the inevitable relevance of science.
Sam Berkovic and Ingrid Scheffer have changed the way the world thinks about epilepsy, a debilitating condition that affects about 50 million people.
Twenty years ago doctors tended to regard most forms of epilepsy as acquired rather than inherited. In other words, they believed epilepsy was mostly due to injury: the result of things like a crack on the head in a car accident, a bad fall in the playground, a tumour, or something having gone wrong in labour. Parents felt responsible and the resulting guilt was enormous.
The two clinician-researchers from The University of Melbourne have led the way in finding a genetic basis for many epilepsies, building on their discovery of the first ever link between a specific gene and a form of epilepsy. Finding that answer has been of profound importance for families.
Along the way, Sam and Ingrid discovered that a particularly severe form of epilepsy, thought to result from vaccination, was actually caused by a gene mutation. This finding dispelled significant concerns about immunisation.
Forty per cent of the energy consumed by industry is used to separate things— in natural gas production, mineral processing, food production, pollution control. The list goes on.
Each offers an application for Matthew Hill’s crystals. He has demonstrated that the space inside metalorganic frameworks (MOFs)—the world’s most porous materials—can be used as efficient and long-lasting filters.
By choosing different combinations of metals and plastics, Matthew’s CSIRO team can make a wide range of customised crystals. Then, using antimatter and synchrotron light, they map the internal pores, determine what each crystal can do and explore potential applications.
