Australian and South American researchers posit wandering “ploonets” as unseen actors in distant solar systems.

Moons ejected from orbits around gas giant exoplanets could explain several astronomical mysteries, an international team of astronomers suggests.

Researchers led by Mario Sucerquia, from the Universidad de Antioquia, Colombia, and Jaime Alvarado-Montes from Australia’s Macquarie University, modelled the likely behaviour of giant exomoons predicted to form around massive planets – and discovered that they would be expelled and sent packing.

Roughly 50% of these ejected moons would survive both the immediate expulsion and avoid any subsequent collision with the planet or the star, ending up as quasi-planets travelling around the host star, but in eccentric “Pluto-like” orbits.

New Guinea is one of the only places in the world where frogs are safe from the species-destroying chytrid fungus. An international team of scientists has published a new paper that shows how to keep it that way, but they need help to carry out their plan.

The chytrid fungus has wiped out more than 90 frog species around the world, and it’s driving hundreds more towards extinction. New Guinea – the world’s largest tropical island, and home to 6% of all known frog species – is one of the last remaining refuges from the deadly infection.

A team of scientists led by researchers from Macquarie University and the University of New England in Australia think they know how to keep the island’s frogs safe, but they need support to establish a long-term program of monitoring and conservation.

Most diamonds are made of cooked seabed.

The diamond on your finger is most likely made of recycled seabed cooked deep in the Earth.

Traces of salt trapped in many diamonds show the stones are formed from ancient seabeds that became buried deep beneath the Earth’s crust, according to new research led by Macquarie University geoscientists.

Location matters for species struggling to survive under a changing climate.

A new study led by Macquarie University has found we need to provide more safe havens for wildlife and plant species to survive under climate change in New South Wales’ west.

Along the Great Dividing Range, the vulnerable spotted-tailed quoll will be forced to move into higher habitats as the climate changes, but can find sanctuary in protected areas like Kosciuszko National Park.

As partners in the $245 million SmartSat CRC announced in Adelaide this morning.

Eighty-four research and industry partners are contributing $190 million investment in cash and in kind to the new Cooperative Research Centre for Smart Satellite Technologies and Analytics, and the Australian government is contributing a further $55 million. The CRC is led by the University of South Australia. 

“A new generation of low-cost smart satellite technology has the potential to enhance agriculture, mining, communication and national security,” says Associate Professor Sam Reisenfeld, who leads Macquarie University’s contribution to the CRC.

Macquarie University and UWA scientists will join forces with two Australian companies to search for new antibiotics in 500,000 species of Australian microbes.

Background information below.

The project will be supported by a $3 million CRC-P grant announced by Australia’s Assistant Minister for Science, Jobs and Innovation, Senator Zed Seselja.

“We have samples of over 500,000 Australian microbes,” says Dr Ernest Lacey, Managing Director of Sydney-based company, Microbial Screening Technologies (MST), and the leader of the project.

“We’ve collected them from the soil in backyards, in paddocks, and forests. We’ve collected them from insects, plants and animals. We’ve gone everywhere to find Australia’s unique microbiome.”

“Each microbe contains a unique cocktail of metabolites. When we find an interesting new molecule, we’ll be relying on Macquarie University researcher Dr Andrew Piggott and his team to help us to work out its structure and mode of action.”

“Then Dr Heng Chooi from UWA will use genomics to unravel how the microbes assemble these metabolites and then boost their productivity.”

“Advanced Veterinary Therapeutics (AVT) is led by Dr Stephen Page and will focus on animal health potential,” says Dr Lacey.

“The CRC-P Program helps businesses, industries and research organisations to work together on short-term projects to develop practical solutions to challenges in key industry sectors,” Assistant Minister Seselja said at the project launch.

The three-year project, “BioAustralis, towards the future”, will harness MST’s unique collection as a source of next-generation antibiotics capable of overcoming microbial resistance. [continue reading…]

And yet the latest research reported in Perth this week suggests they have little to fear from ‘nano-sunscreens’.

Posted on behalf of ICONN 2012: Australia’s International Conference on Nanoscience and Nanotechnology

More than three in five Australians are concerned enough about the health implications of nanoparticles in sunscreens to want to know more about their impact. And while the initial scientific information released suggests little cause for alarm, it does justify the community’s confusion.

That’s the message that emerges from a survey and three research papers on nanoparticles in sunscreens presented at the 2012 International Conference on Nanoscience and Nanotechnology (ICONN) in Perth this week. [continue reading…]

2011 marks the fifth year that L’Oréal Australia will award its For Women in Science Fellowships to Australian early-career female scientists.

Since its inception in 2007, the Fellowships, worth $20,000 each, have been awarded to 14 outstanding female scientists who have used the award to increase their impact in their chosen field of science, provide support to managing both families and lab work, and jumpstart their independent careers in science.
