When kelpie-cross Kip sits down while riding a paddle board, scientists pay attention
With a quickening heart, Rutter caught up to Daisy – a small, eight-year-old Lagotto Romagnolo with a brown woolly coat as tight as an '80s perm – and spied in the dirt beside her a tiny burrow, into which he fed an endoscope camera. 'And I could see this tiny, gorgeous [Victorian grassless] earless dragon face peering back at me,' Rutter says, referring to the 15-centimetre-long creature – the most imperilled reptile in Australia. 'It was an absolutely amazing, career-defining moment. A moment of joy.'
Estimates of the sensitivity of dog noses relative to human noses vary wildly, from 10,000 to 1 million times more sensitive. Whatever the number, it explains why humans have long made use of dogs' highly tuned olfactory abilities to aid them in everything from hunting game to detecting cadavers, drugs, explosives, cancer – and endangered species. As of June this year, Rutter and his (human and canine) colleagues at Zoos Victoria's Wildlife Detection Dog Program have assisted threatened-species biologists in finding 15 Victorian grassland earless dragons, a species not seen for half a century and thought extinct until one was found in 2023.
The dog squad, based at Healesville Sanctuary within the Coranderrk Bushland Nature Conservation Reserve 60 kilometres north-east of Melbourne, isn't only searching for the tiny reptile, which is now the subject of a breeding program. The squad's five dogs are also trained to sniff out broad-toothed rats, Tasmanian devils, Baw Baw frogs and platypuses.
In lieu of a salary and superannuation, the dogs, who live on site, are compensated with hugs, treats, soft toys and play. 'We call it a 'party',' says Rutter, who was never allowed a dog growing up and is now making up for it. 'So when they find their target, we kind of get down on our hands and knees and have a party with them. Some of the dogs really like a tennis ball and to let off a lot of steam. Some like a high-value reward, like a nice bit of boiled-up venison or some chicken. Daisy, she's a cuddler.'
The training process is a slow one, says Naomi Hodgens, fellow detection-dog team member along with La Toya Jamieson and Rutter. Over about nine months, trainers begin familiarising the dogs with their new target while teaching them to ignore competing odours. Eventually, the dogs are taken out into the field to find their species in situ.

Hodgens and Jamieson are currently surveying platypus numbers within the Coranderrk Creek. To combat some of the hard-to-access bushland, Kip, a 10-year-old kelpie-cross, and Moss, a six-year-old labrador, have each been trained by Jamieson to stand on the bow of paddle boards while Hodgens and Jamieson navigate through the creek. When the boards come within a metre or two of an occupied platypus burrow, which can be hidden from human view, the dogs sit and point their noses in the direction of the burrow.

Deanna tried IVF with the lot. None of the costly, unproven add-ons worked, so she went back to basics
Australia's health ministers last month ordered a rapid review of the nation's assisted reproductive sector following a series of bungles and scandals, to determine if greater regulation can increase the safety and transparency of fertility clinics. Victoria is leading the national review, and a Victorian government spokesperson confirmed IVF add-on services would be included in consideration of existing or potential new legislative framework. 'A dedicated team has been established to undertake the review and will report back within three months,' the spokesperson said. Australia has the fifth-highest rate of IVF, fuelled by the strength of the commercial fertility sector and Medicare rebates with broad eligibility criteria that mean patients can continue coming back for cycles regardless of their chances of success. Four out five women accessing IVF also use add-on services during their treatment, which can greatly add to their costs as well as the profits and marketability of the clinics, but which may not increase the chances of success. An analysis of the non-core services being offered to Australian fertility patients by University of Melbourne researchers, prepared for this masthead, highlights the high costs and lack of evidence supporting services commonly upsold to potentially emotionally vulnerable patients. It reveals 44 treatment types ranging from free to $5000, and taking in everything from vitamins to plasma being injected into ovaries, genetic testing of embryos, injecting a single sperm directly into an egg and endometrial scratching, have little to no influence on the chances of having a live birth, pregnancy or miscarriage. Loading The analysis follows the launch of the Evidence-based IVF website in April, which is led by the University of Melbourne's Dr Sarah Lensen as an effort to better inform people undergoing IVF of the unproven add-ons. 'There are research articles out there on these different add-ons but the quality, broadly speaking, is really poor. Different providers are willing to draw the line in different places in terms of how much evidence they think they need before they're willing to offer or recommend something,' Lensen said. 'Sometimes there's a cost for special IVF conception vitamins or whatever, but they're probably pretty low risk, and they're not as big of a deal. 'Down the other end of the spectrum, there's the super-expensive $1000 treatment options that also come with risks because they're playing with patients' immune systems or injecting things into their ovaries that we don't really know what's going to happen. 'A lot of the add-ons that get offered slip through the cracks in terms of the existing regulatory system.' In Deanna Carr's case, she underwent two normal but unsuccessful cycles of IVF before adding steroids, blood thinners, aspirin and clexane during two further cycles. Determined more had to be done, Carr followed advice from online fertility forums and moved to one of Australia's largest clinics to seek out a specialist known for pushing the envelope. 'There's lots of conversation about which specialists to see, because these specialists are willing to be a lot more experimental – and, when we say experimental, it is literally meaning experimental. 'They're willing to try more add-ons, regardless of how inclined the research is to say that it doesn't work.' Tests at that clinic found Carr had a partial DQ Alpha gene match which may make her body more likely to attack or reject an embryo, though research suggests treatment for it does not significantly improve IVF success rates. To address the issue, a team of specialists gave Carr lymphocyte membrane immunotherapy, in which up to eight vials of blood were taken from her husband so his white blood cells could be extracted and then injected into her arm to correct her immune system with material that is genetically matched to their embryo. 'It's like weird blood brother stuff, and quite expensive,' Carr said. She was given a toxic cocktail of drugs including naltrexone and tacrolimus, which are more commonly used to treat cancer, as well as an intralipid infusion to 'knock out' her immune system. Added together, this cycle cost more than $8000. 'It didn't work. It ended up the same way all our other cycles ended,' she said. Carr's specialists then offered to step up the add-on treatments even further. They proposed a $5000 EMMA and ALICE test which would have seen Carr undergo another full IVF cycle but, rather than try for a pregnancy, the doctors would take a biopsy of her uterus to see if bacteria were present that might be impacting her pregnancies. If it found abnormalities, Carr was then to be prescribed cefalexin – a common antibiotic used for infections and cheaply available on the Pharmaceutical Benefits Scheme. 'It's what the doctor would give you for a sore throat. Why would they make me pay five grand for it? Why not just give me the medication?' Rather than spending $12,000 for another add-on-laden IVF cycle, Carr consulted the Evidence-based IVF site and realised there was little science to support the proposed treatment, then switched clinics to undergo a traditional – and successful – cycle. 'You get persuaded to add on because you obviously want it to work, and you're already spending so much, so this can financially tip you over the edge,' she said. 'A lot of these IVF companies know that. It does feel really unethical [because] a lot of the time people aren't being provided with proper information around the add-ons that are being suggested and the efficacy around them. And people are really desperate, so they'll just keep saying yes to things.' A Macquarie University professor of bioethics in the discipline of philosophy, Wendy Lipworth, last year published a study based on interviews with 31 doctors working in assisted-reproductive technology to see what their 'moral justification' for using add-ons was. The specialists' responses revealed evidence and innovation was not the driving consideration in many instances, and that regulatory reforms to only allow the use of unproven treatments in the context of formal scientific evaluation might be required. Lipworth said add-ons were often marketed as a point of difference between clinics, which may undermine individual doctors' ability not to offer them for patients. As a result, she believes any new regulation would need to focus on the clinics and what they are offering, rather than individual doctors wanting the best for their patients. 'Generally, there should be some expectation that they might at least be beneficial, even if there's no good evidence for it. That's a real balancing act,' Lipworth said. 'In fertility, the balance is going a little too far in the direction of too many things being offered without enough evidence. 'There might be room for some more regulation of how the products are advertised, how patients come to know about them, what they charge for them and so on. But the very act of using them is not in and of itself in any way unethical. 'What really matters is that people know that they're getting treatment for which there is not good evidence, and that they are able to make informed decisions about whether or not to use them. Loading 'That doesn't mean that anything goes and that patients should necessarily be able to walk into a doctor's surgery and say, 'my friend saw this on Facebook', or 'my friend used this and she got pregnant, therefore I want you to offer it to me'. 'There is still a duty of care to offer things that you, at the very, very least, are absolutely certain won't do harm.' Add-ons are not the only factor separating clinics, or the fees they charge. Lensen said premium clinics typically provide continuity of care so patients always get to see the same specialist and nurse, as well as improved customer service, which may not be provided at low-cost or public clinics. And, in many cases, the proliferation of add-on services is often more patient-driven than due to marketing by doctors or their clinics – which is why Lensen believes reforms are even more important, so regulators can step in when doctors fail to uphold their responsibility to dissuade patients from treatments that may not be in their best interests. 'The evidence is not that strong, but the patients are asking for it, or the clinic down the road is offering it, and so they end up using it too. But then when the research community does come out with robust evidence later, I think they do act,' she said. 'So it would be nice if we said from 'now on, no more offering a high dose of corticosteroids to patients. If you want to do that, they can take part in a placebo controlled trial'. 'A lot of the time, though, regulations are not aligned with the commercial interests of whoever they're trying to regulate – that's the whole reason we need them.'

SA Algal Bloom: 'Any way you look at it, what is happening here is a national disaster'
On today's program: South Australia's government has announced it will match the Commonwealth's $14 million funding package to help the state grapple with its toxic algal bloom outbreak. The $28 million package spans science and research, clean-ups, industry and community support and communications. But what caused the bloom is yet to be nailed down. This is all happening in the part of the world that Dr Mike Bossley has made his life work. "It's very concerning to see an ecosystem dying in front of your eyes. As someone who has spent most of my adult life trying to protect the ocean it's having a huge emotional impact not just on me but anyone who loves the ocean." Reporter: Sinead Mangan with cetacean researcher and environmentalist Dr Michael Bossley The remote Aboriginal community of Gunbalanya is reeling after the NT government quietly reallocated $20 million of funding that was promised for a new health centre. The current facility is so dilapidated and inappropriate that many patients avoid it altogether, delaying preventative treatment and sometimes ending up at Royal Darwin Hospital. Adding to concerns is the fact the main road into town travels over the notorious Cahills Crossing, which is frequently flooded by saltwater crocodiles, blocking road access in the case of emergencies. Reporter: Samantha Dick (Darwin) Accurate weather forecasting has always been a challenge for the Victorian town of Mansfield because of its proximity to the Great Dividing Range. Fed up with the inaccurate forecasts from a station 30 kilometres away, the community has banded together to build their own weather tower. Reporter: Coco Veldkamp and Callum Marshall (Shepparton)
