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.
Better vaccines are needed for the global fight against tuberculosis (TB). The Global Fund reports an estimated nine million new cases globally per year of TB, which is second only to AIDS as the world’s most deadly infectious disease.
Indonesia had more than 320,000 reported cases in 2014 according to the World Health Organization, while Australia’s reported cases were just over 1,000. But the rise of drug-resistant TB poses a threat to all countries.

‘Buddy’ cells that trigger blood stem cells to fully-develop have been discovered by a team of Australian scientists. The finding, in zebrafish, may hold the key to creating blood on demand in the lab.
Everyday medical procedures can require litres of donated blood; and blood stem cells – which can turn into any one of the different types of blood cell – are often used in treatments for leukaemia, lymphoma, and other blood cancers.
Scientists in Australia and California have worked out how to unboil an egg. It may sound like an odd discovery, but it’s changed the way scientists think about manipulating proteins, an industry worth AU$160 billion per year.
Flinders University Professor Colin Raston and his team have developed Vortex Fluid Technology – using mechanical energy, or spinning, to reverse the effects of thermal energy, or boiling.
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.

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.
A new diagnostic system used to detect cancer cells in small blood samples could next be turned towards filtering a patient’s entire system to remove those dangerous cells – like a dialysis machine for cancer – says an Australian researcher who helped develop the system.
The technique was developed for cancer diagnosis, and is capable of detecting (and removing) a tiny handful of cancer-spreading cells from amongst the billions of healthy cells in a small blood sample.
The revolutionary system, which works to diagnose cancer at a tenth of the cost of competing technologies, is now in clinical trials in the US, UK, Singapore and Australia, and is in the process of being commercialised by Clearbridge BioMedics PteLtd in Singapore.

The possibility of a link between vitamin D deficiency and pneumonia is being investigated in two studies by Indonesian and Australian scientists in Indonesia.
They’re tracking the incidence and severity in early childhood of respiratory tract infections, including the common cold, asthma, pneumonia, and bronchiolitis, in hospitals and the community, in the hope of providing more information for treatment and management for respiratory diseases.
Pneumonia is the number one killer of children under five in the country, and around six million young Indonesians suffer from it each year, according to a 2008 study. This collaboration is going to update those 2008 figures, and hopefully lower them – while trying to find the causes of it and other respiratory tract infections.

He and his colleagues are printing 3D plastic body parts of unprecedented detail and accuracy that have the potential to revolutionise anatomy teaching.
Anatomy students need a high degree of familiarity with the intricate details of the human body. That ideally comes with repeated handling and hands-on study. But students are often reluctant to touch a cadaver any more than necessary.
Removing the emotional, ethical and physical restrictions to close handling and repeated study improves the students’ familiarity with the human body. Another advantage of the printing is the expertly applied false colouring picking out intricate nerves, veins, arteries and ligaments that are much harder to identify in preserved cadavers.
The waters off Japan’s tropical Okinawa Islands are home to hundreds of species of coral. The reefs attract a rich diversity of life: fish, turtles, whale sharks, and… the crown-of-thorns starfish.
Five thousand kilometres to the south is the Great Barrier Reef—the world’s largest reef system and one of the richest and most diverse natural ecosystems on Earth. The Australian Government is committed to protecting the Reef and has developed a plan to 2050 to ensure the sustainability of the Reef. But the Reef has lost half its coral cover in the past 30 years and periodic plagues of crown-of-thorns are responsible for more than forty per cent of the coral loss.
