A new fibre optic medical tool is revolutionising our understanding of serious but socially embarrassing digestive illnesses, such as constipation, diarrhoea and irritable bowel syndrome. Thanks to this device, medical scientists can see for the first time the coordinated, fine and complex muscular activity of the human digestive system in action.
CSIRO optical physicist Dr John Arkwright, together with Dr Philip Dinning, of Flinders University, collected a 2011 Eureka Prize for their creation of the fibre optic catheter, which gleans information about digestive function by measuring pressure.

A new instrument at the Australian Astronomical Observatory (AAO) can sample the light coming from hundreds of galaxies per night—which can tell us new things about the universe.
Sydney-AAO Multi-object Integral field spectrograph (SAMI) can look at up to 100 galaxies in a night, because it can look at 60 different regions in each of 13 different galaxies, all at once.
But most observatories around the world can only do one galaxy at a time.

Imagine an extremely large optical telescope fitted with detectors that can selectively collect light from a particular section of the telescope’s focal plane. Using revolutionary robotic technology called Starbugs, the detector will reconfigure itself in real time to collect from any particular area of the image, and will feed the data into any analytical instrument.
That’s exactly what Matthew Colless and his team at the Australian Astronomical Observatory have in mind with the development of MANIFEST (the many-instrument fibre system)—which make use of the special photonic technologies developed by Joss Bland-Hawthorn and his team at the University of Sydney.

Using the Gemini South telescope in Chile, a team of astronomers led by Joss Bland-Hawthorn of the University of Sydney revealed the faint, outer regions of the galaxy called NGC 300, showing that the galaxy is at least twice the size as thought previously. The findings suggest that our own Milky Way galaxy could also be bigger than the textbooks say.
But Joss’s telescope observations are just a part of his contribution to astronomy. He is also helping to pioneer a new technology known as astrophotonics, which uses optical systems to improve our understanding of the Universe. Continue reading Bringing dark corners of the Universe to light
The only way to find out whether the internal structures of an aircraft are corroded is to pull the plane apart and look. But new nanotechnology-based techniques being developed by Prof. Tanya Monro, Director of University of Adelaide’s Centre of Expertise in Photonics, in collaboration with the Defence Science and Technology Organisation, could make costly visual inspection in preventive aircraft maintenance a thing of the past.
