Toxins from snakes, spiders, jellyfish and scorpions are helping scientists to better understand how pain works, with the hope of managing chronic pain more effectively.
Pain comes in many forms, requiring different treatments and often making it difficult to manage. Many painkillers have negative side effects including addiction, and for some the painkillers don’t even work.
“Many drugs achieve around 50 per cent pain relief in only one-third of patients. That’s not good enough,” says Dr Irina Vetter, Deputy Director of the Institute for Molecular Bioscience’s Centre for Pain Research at The University of Queensland.
How much fish move around is critical information for fisheries managers—for example they need to know if fish caught off Brisbane are a separate population to those caught off Cairns. Different tracking techniques, such as physical tags or genetic mapping, can be used but each method has its weaknesses.
A team of mathematicians is using pre-existing data on Spanish mackerel, using their hitchhiking parasites to track fish movements and model the populations.
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.

Australia and Japan are both island nations with vast maritime reserves and responsibilities. Together we’re developing the science needed to understand, use, enjoy and protect our unique marine ecosystems. And we’re collaborating to solve some of the mysteries of the ocean systems that drive the world’s climate.
Attack of the giant starfish
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.

Small Australian sharks have been exposed as bigger homebodies than previously thought, in a study that took an existing chemical tracking technique and made it work for Great Barrier Reef sharks.
The study found that the travel history of the Australian sharpnose shark was written in their blood—with chemical ‘fin-prints’ showing they tended to stay within smaller areas than previously believed.
“Small-bodied sharks that are both predator and prey, such as the Australian sharpnose, may be particularly important links between food webs,” says lead researcher Dr Sam Munroe, who studied the sharks while at James Cook University in Townsville.
“Information on their movements can improve our understanding of how the ecosystems function, while also helping us predict species most at risk from the impacts of a changing environment.”
Hugh Possingham and his team are making conservation more efficient. They’re helping to save less fashionable threatened species by getting more bang for the bucks donated to cute and cuddly species.
The team of ecologists and mathematicians in the Australian Research Council Centre of Excellence in Environmental Decisions (CEED) worked with the New Zealand government to assess how to better spend money that is donated to conservation. They’ve shown that by protecting habitats shared by several different species, the money donated to charismatic ones can be stretched further to save other species as well.
“The way we currently attempt to save species is inefficient, choosing species that are popular or charismatic, like koalas and tigers, over those that are less well known or even ugly, like the blobfish,” says Hugh, ARC Laureate Fellow and Director of CEED.
Relief isn’t a term commonly associated with spiders, but Glenn King has found promising molecules in tarantula venom that he hopes will bring respite to the one in five Australian adults suffering from chronic pain.
