Early results from Australia-wide experiment suggest being outdoors can be a good way to trigger “aha” moments.

People are most likely to have a sudden bright idea when out in the bush – or lying in bed.

That’s one of the early observations arising from The Aha! Challenge, the month-long Australia-wide science experiment that kicked off during National Science Week and runs until the end of August.

The experiment, which revolves around a series of online brainteasers, aims to explore sudden bursts of clarity and insight, and their role in problem-solving. In effect, it’s a nationwide quest to find the things that make you go “aha!”…

And so far the results have been very revealing.

Scientists urge priority action on hundreds of surviving reefs.

The majority of 2500 reefs surveyed in a major international exercise retain the coral species that give them their distinctive structure.

More than 80 marine scientists, including several from Australia, contributed to the study, which is published in the journal, Nature Ecology and Evolution.

Australia-UK researchers identify ancient protein pumps that make bacteria tough to treat – but could be key to new green polymers

The molecular machinery used by bacteria to resist chemicals designed to kill them could also help produce precursors for a new generation of nylon and other polymers, according to new research by scientists from Australia and the UK.

“Resistance to artificial antiseptics appears to be a lucky accident for the bacteria, and it could also be useful for humans,” says Professor Ian Paulsen of Australia’s Macquarie University, one of the leaders of the research group.

Researchers set up Australia-wide experiment to explore why and when the pennies drop.

Scientists want to know the things that make you go “aha!”.

Throughout August, researchers from the University of Melbourne are conducting a country-wide citizen science project to better understand how the human brain works.

The focus of the project, dubbed The Aha! Challenge, is to investigate the kind of sudden problem-solving insight that makes you spontaneously exclaim “yes!” or “at last!” or, indeed, “aha!”. It’s the ABC’s community project for National Science Week.

Australian scientists develop cheap and rapid way to identify antibiotic-resistant golden staph (MRSA).

A combination of off-the-shelf quantum dot nanotechnology and a smartphone camera soon could allow doctors to identify antibiotic-resistant bacteria in just 40 minutes, potentially saving patient lives.

Staphylococcus aureus (golden staph), is a common form of bacterium that causes serious and sometimes fatal conditions such as pneumonia and heart valve infections. Of particular concern is a strain that does not respond to methicillin, the antibiotic of first resort, and is known as methicillin-resistant S. aureus, or MRSA.

Recent reports estimate that 700 000 deaths globally could be attributed to antimicrobial resistance, such as methicillin-resistance. Rapid identification of MRSA is essential for effective treatment, but current methods make it a challenging process, even within well-equipped hospitals.

Chinese-Australian research finds climate change good news, and solves an evolutionary mystery

Baby turtles influence their gender by moving around inside their eggs, research has revealed.

The idea that an embryo reptile can act in a way that affects its chances of developing as male or female has long been thought impossible, but findings by scientists from China and Australia have now provided clear proof of the process.

The research, published in the journal Current Biology, solves a long-standing evolutionary mystery – and offers hope that at least some species thought especially vulnerable to effects of climate change will prove more robust than thought.

Australian-led astronomers find the most iron-poor star in the Galaxy, hinting at the nature of the first stars in the Universe.

A newly discovered ancient star containing a record-low amount of iron carries evidence of a class of even older stars, long hypothesised but assumed to have vanished.

In a paper published in the journal Monthly Notices of the Royal Astronomical Society: Letters, researchers led by Dr Thomas Nordlander of the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) confirm the existence of an ultra-metal-poor red giant star, located in the halo of the Milky Way, on the other side of the Galaxy about 35,000 light-years from Earth.

Macquarie University’s Professor Rob Harcourt urges Oceania-wide action to safeguard several species.

Sharks in Australian waters are well protected but are at risk as soon as they leave them, a new international study reveals.

The study compiled by 150 scientists around the world – including 26 with ties to Australia – has found that even in the most remote parts of the world’s oceans migratory sharks are in severe danger from commercial fishing fleets, new research reveals.

In a paper published in the journal Nature, more than 150 scientists, including Professor Rob Harcourt from the Department of Biological Sciences at Australia’s Macquarie University, report that the sharks – which include iconic species such as the shortfin mako (Isurus oxyrinchus)  and the great white (Carcharodon carcharias) – congregate in food-rich areas that are also prime hunting grounds for commercial longline fishing fleets.

Dr Stuart Ryder is venturing into the stratosphere on a NASA jet to study the birthplace of massive stars.

Macquarie University astronomer Dr Stuart Ryder is in New Zealand to hitch a ride on a NASA jet and take a closer look at how stars are born in one of the most active stellar nurseries ever seen.

Australian research finds little lizards learn very quickly.

Young Australian eastern blue-tongue lizards (Tiliqua scincoides) are every bit as clever as adults, researchers have found.

Life is hard for baby blue-tongues. As soon as they are born, they are on their own, with neither parental support nor protection. Adults of the species can grow to 600 millimetres long and enjoy the benefits of thick scales and a powerful bite, but the young are much smaller and thus more vulnerable to predation.

And that means they have to box clever if they are to survive.

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.

Melbourne researchers have found that 80 percent of people with quadriplegic spinal injuries have sleep apnoea. It’s having a big effect on their lives but they don’t know they have it, and they don’t know it can be treated.

The researchers are calling for everyone with quadriplegia to see a doctor if they are tired and fatigued, and they’ve produced videos demonstrating the impact on patients’ lives.

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.

Ten per cent of the oxygen we breathe comes from just one kind of bacteria in the ocean.

Now laboratory tests have shown that these bacteria are susceptible to plastic pollution, according to a study published in Communications Biology tonight.

“We found that exposure to chemicals leaching from plastic pollution interfered with the growth, photosynthesis and oxygen production of Prochlorococcus, the ocean’s most abundant photosynthetic bacteria,” says lead author and Macquarie University researcher Dr Sasha Tetu.

“Now we’d like to explore if plastic pollution is having the same impact on these microbes in the ocean.”
