We all rely on GPS to tell us where we are and where we’re
going. The US government’s global network of 30+ satellites guides planes,
ships, cars, tractors and much more. The latest GPS systems can provide mm- to
cm-accuracy using advanced equipment and technique.
But GPS isn’t the only game in town. There are other
global systems, and regional systems that we can tap into.
Curtin University researchers have explored the potential
of regional navigation satellite systems (RNSSs) for Western Australian users.
Two such systems are the QZSS operated by Japan and the IRNSS operated by
While coral reefs around the world are feeling the heat, little-known reefs in Australia’s Kimberley region are prospering, despite living in some of the toughest conditions—and scientists aren’t yet sure why.
The discovery has particular significance this summer with fears of a severe coral bleaching event to hit our northern waters—the result of steadily rising sea temperatures and a strong seasonal El Niño.
WA researchers have found that while coral reefs all around the world are feeling the heat of rising temperatures, some inshore reefs in the Kimberley region’s Bonaparte Archipelago are prospering, despite living in some of the toughest conditions.

Australian citizen scientists are helping to catch shooting stars in the vast skies of outback Australia and to track the impact of climate change on species in our warming oceans.
Curtin University’s Fireballs in the Sky project invites people to use a smartphone app to record and submit the time, location, trajectory and appearance of meteors they spot.
By triangulating these reports with observations from an array of cameras in remote Western and South Australia, scientists can try to determine where the meteorite may have come from and where it landed.
Far outback in Western Australia, 32 tiles—flat, stationary sensors—each carrying 16 dipole antennas have begun collecting scientific data.
These first tiles will ultimately form part of a much bigger array of 512 tiles, the Murchison Widefield Array (MWA)—Australia’s second Square Kilometre Array (SKA) demonstrator project. Like CSIRO’s Australian SKA Pathfinder (ASKAP), the MWA is being built at the remote, radio-quiet Murchison Radio-astronomy Observatory (MRO). Continue reading Telescope of tiles→
Dr Kate Trinajstic has used synchrotron light and CT scanning to see through rock, in the process discovering how ancient fish developed teeth, jaws and even a womb. Her work is increasing our understanding of how life on Earth evolved.
About 380 million years ago in what is now the Kimberley Ranges in Western Australia, a vast barrier reef formed. In what would have been the inter-reef basins, large numbers of fish were buried relatively intact. Protective limestone balls formed around them and preserved them. When these balls are treated with acetic acid, the main component of vinegar, the surrounding rock dissolves, leaving only fossilised fish bones.
But in the course of studying hundreds of these dissolving balls, Kate began to see what looked like muscle fibres between the bones. She was eventually able to convince her colleagues that irreplaceable soft tissue detail was being lost in the acid treatments. Continue reading Seeing fish through rocks→
Far outback in Western Australia, at the Murchison Radio Astronomy Observatory located on Boolardy Station, 315 km north-east of Geraldton, 32 tiles each carrying 16 dipole antennas have begun to collect scientific data on the Sun. At the same time they are providing engineering information to be used to extend the facility to a much bigger array of 512 tiles – the Murchison Widefield Array (MWA).
Western Australia’s International Centre for Radio Astronomy Research (ICRAR) is only three months old but is rapidly expanding—much like the early Universe. ICRAR’s scientists have ambitious projects ahead contributing to global science and engineering through the SKA.
