Rock art expert breaks silence over Burrup emissions study controversy
A leading statistician on an emissions study into an ancient West Australian rock art site has spoken supporting an 800-page report, days after blasting WA bureaucrats for 'unacceptable interference' by altering a graph in a separate summary of that report.
The report on monitoring of industrial emissions near the site on the Burrup Peninsula in the state's north-west was released last Friday, and lauded by industry and the Cook government as proof that modern industrial emissions were not currently impacting the ancient petroglyph images carved into the site's striking rock landforms.
That conclusion was rubbished by world-renowned rock art expert Ben Smith, who said the 800-page report showed the opposite.
The Murujuga rock art monitoring program is a $27 million joint effort between Curtin University scientists, Murujuga Aboriginal Corporation and the Department of Water and Environmental Regulation.
Its release came days before Federal Environment Minister Murray Watt approved a 40-year extension to the life of Woodside's North West Shelf assets – among which are a gas plant releasing some of the emissions being monitored.
The report was published alongside an eight-page summary featuring graphs showing benchmark levels for acceptable pollution on the Burrup.
The ABC reported Curtin University Emeritus Professor Adrian Baddeley, who was the report's chief statistician, complained in an email to DWER on Tuesday that one of those graphs had been altered on the summary.
The alteration removed a line showed in the main report, showing an early warning threshold of pollution on the Burrup.
Baddeley, who told a pro-Palestine rally at Curtin last May universities had become 'more corporate, much more authoritarian, much more coercive' wrote to the government department:

Probucol: Hope wonder drug can treat both Parkinson's and Alzheimer's diseases in new Perth trial
A new clinical trial to treat Parkinson's disease will start in Perth next year using a drug currently under investigation as a ground-breaking treatment for Alzheimer's disease. Probucol, a drug originally used in the 1980s to treat cardiovascular disease and lower cholesterol, has since been found to have potent anti-inflammatory and anti-oxidant effects on the brain. The Probucol in Alzheimer's disease study, which started in 2021 and has so far recruited around 100 people, has just received ethics approval to extend treatment access for participants for an additional two years. Professor John Mamo, the trial's chief investigator, said results from the two-year double blind trial were not yet available, but the open label extension was an 'exciting opportunity' for those taking part. 'The scientific significance lies in combining data from both the PIA study and the open-label extension. We'll gain insight into the efficacy of four years of treatment and also understand the impact of delaying treatment by two years — as in the case of those originally randomised to placebo,' Professor Mamo said. Professor Mamo, Head of Neurovascular and Metabolic Diseases at the Perron Institute and Curtin University, said Probucol has properties that are highly relevant across several neurodegenerative conditions and Parkinson's disease was the next target for investigation. In the context of Alzheimer's, Professor Mamo and his research team discovered that amyloid, a key protein implicated in the disease, is secreted outside the brain as part of fat-carrying particles called lipoproteins. They showed that when amyloid-rich lipoproteins are excessively abundant in the blood, they compromise the integrity of microscopic brain vessels, allowing amyloid to leak into the brain and trigger inflammation. 'We found that Probucol powerfully suppresses the synthesis and secretion of amyloid into the blood, preserving brain capillaries and preventing brain cell loss due to inflammation,' he said. But Professor Mamo said that amyloid plaque build-up in the brain likely represents the end stage of this damaging process — suggesting it may be the metabolic process beforehand, not the plaque itself, that principally drives the disease. Preclinical studies have shown that Probucol can profoundly preserve cognitive function in models of Alzheimer's. He said new monoclonal antibody therapies available to treat Alzheimer's were highly effective at reducing plaque burden but only had modest effects on halting cognitive decline. 'It's still unclear whether plaques are more a consequence than a cause,' he said. The Parkinson's trial will start in 2026 through the Perron Institute and Curtin University with Perth being the main research site. Alzheimer's disease is the biggest killer of women in Australia, and the second biggest for men and women. Professor Mamo said women with the disease deteriorate at three times the rate of men. Parkinson's disease is the fastest growing neurogenerative disease with 150,000 people living with it in Australia and 20 per cent of them are below retirement age. The Probucol in Alzheimer's study is looking to recruit around 50 more people who can contact the PIA study team on piastudy@ They do not need a doctor's referral or a diagnosis of Alzheimer's or dementia to be considered and can contact the PIA study team on piastudy@ or 0 468 532 458 .

Sian Williams: Celebrating the UN's International Day of Play sets up healthy habits for life
Childhood is the most rapid period of growth and development across over entire lifespan for our minds and bodies. Whilst our bones grow longer, our muscles get stronger and learn how to coordinate together to produce different (and more efficient) movements. Meanwhile, our brains are forming and reorganising new neural pathways to help us learn, think and move — a process called neuroplasticity which is at its peak through childhood. This is why it is so much easier for children to learn a new skill, instrument or language compared to learning as an adult. Playing is an absolutely vital aspect of this development in children. It's a universal language which fosters resilience, creativity, and innovation in everyone — but particularly children. Today marks the UN's International Day of Play, which aims to preserve, promote and prioritise playing so all people, especially children, can reap the rewards and thrive to their full potential. Fostering environments rich in movement and play for children can help capitalise on this period of peak development, supporting not only their physical development but also their cognitive, social and emotional growth, and learning and communication. For kids, play is like their job: how they play, why they play, where, who with and when, is very important — and all kids deserve the right to play for the same opportunities to thrive. But the positive effects of play can go even further. Most of my research at Curtin University has been focused on childhood-onset disabilities such as cerebral palsy. In this space, we talk a lot about the 'F words': functioning, family, fitness, fun, friends and future. We work beyond impairments and diagnoses; in doing so we are creating opportunities for health and wellbeing benefits for children and their families. Supporting a child to develop their fitness isn't to help them win a running race — though this can also be an important goal. It could allow them to join in and keep up with their peers in playground games and build confidence, form friendships and learn to navigate social behaviours. It can also help children be able to get between classes in time or give a child more energy to complete self-care activities to maintain some independence. It has been well established that physical activity participation and fitness levels are lower for children with disabilities such as cerebral palsy, down syndrome and autism spectrum disorder, which is believed to also contribute to higher risk of preventable secondary health conditions. For many children with disabilities, the opportunities for play and movement are not the same. Sometimes, all that's needed may be some equipment modifications, adaptations to the activity, or perhaps some additional support from a trained health professional. We tend to see children with disabilities just haven't had the same chances to be active, to try things out, to win, to lose — to take part in their chosen 'job' as a child to play. A lot of research on barriers to physical activity will talk about things like perceived lack of time, access to facilities, costs, and motivation. This can also be true for children, with the added challenge that we need to factor in the possible barries for the child and their family. The good news is the social and physical environment we create for our kids will be hugely influential for facilitating physical activity. We tend to see this a lot for kids with disability, that sometimes they just haven't had the same chances to be active, to try things out, to win, to lose — to take part in their chosen 'occupation' as a child to play. Over the last couple of decades, we have continued to see a concerning decline in Fundamental Movement Skill proficiency in our Aussie kids. These are the basic building blocks of physical activity, helping children develop coordination, balance, and confidence in movement, including skills such as locomotor (e.g. running and hopping), manipulative or object control (e.g. catching and throwing) and stability (e.g. balancing and twisting). We suspect this decline might be due to an interaction of several factors, such as changes in play environments, reduced societal physical literacy, increased screen time, reduced physical activity and changes in parenting styles (e.g. overprotection with fear of injury, employment circumstances). As a goal, we want our kids to aim for at least 60 minutes of moderate to vigorous physical activity per day involving mainly aerobic activities to make their heartbeat faster, plus several hours of a variety of light activities per day. The 60 minutes doesn't need to be in one hit either: it can be made up of shorter bursts of activity throughout the day Ideally, children will also include vigorous activities which strengthen the muscles and bones into their 60 minutes, three days a week. This does not mean we need to be getting our kids on the treadmill or in the gym; physical activity can come in all forms and for kids, this will often include playground games and activities. The best form of physical activity for a child is an activity they enjoy: if they aren't going to have fun, they aren't going to want to engage. The smartest thing we can do is provide our kids with a variety of activities to choose from, try them out and see what they like (including free and structured play). When they do take part, the emphasis should be on participation rather than performance, as this can help build their self-efficacy, enjoyment, and motivation. Engagement when they are young can lay the foundations of a lifelong relationship with physical activity in our kids, which will benefit them beyond childhood and for the rest of their lives.

Fears for heritage site as gas plant expansion approved
Industrial pollution is damaging priceless rock art, an expert says amid protests over a decision to extend the life of a major gas hub. Woodside's North West Shelf project - which hosts Australia's biggest gas export plant - has been given the green light by the federal government to keep operating until 2070. The Australian energy giant still has to accept conditions around heritage and air quality at the project on Western Australia's Burrup Peninsula, home to ancient rock art, before the approval is made official. The approval has angered traditional owners, climate activists and scientists who have researched the impact of industrial pollution on the rock art at Murujuga. A report into pollution at the site, linked to a $27 million rock art monitoring project, was only released by the WA government a week before federal Environment Minister Murray Watt announced the approval. Benjamin Smith, an archaeologist at the University of Western Australia, said the executive summary did not reflect the key findings of the 800-page report by Curtin University scientists who he claimed were gagged from speaking publicly about it. "They were outraged that their report and the integrity of their academic findings had been misrepresented." Professor Smith told AAP the Curtin scientists felt the summary had "lied about their findings" so he was speaking out about a cover-up by departmental "spin doctors". The Cook government has dismissed the claims as offensive and factually incorrect. The Curtin scientists subjected rocks in a climate chamber to acidic pollution equivalent to emissions from the Burrup gas plants and found all the rocks showed evidence of degradation. Prof Smith said the Curtin research and his own studies showed the pollutants would eat away at the manganese in the rocks until they developed "holes like a Swiss cheese" that then caused the rock surfaces to break down. "It is direct evidence for the first time from a government study that industrial pollution is damaging the rock art of Murujuga," he said. The damage could be mitigated by putting scrubbers on the industrial stacks to filter emissions and reduce pollution but the best solution was to switch the plants' power from gas to electricity, Prof Smith said. "If you transformed all of those plants to electricity ... they could operate cleanly and we could have the perfect solution, which is profitable industry operating responsibly alongside the world's most important rock art site." Prof Smith said the famous Lascaux caves in France held only a few hundred wall paintings and dated back 17,000 years. But the rock art at Murujuga has a million images going back at least 50,000 years, including the world's first-known depiction of a human face and images of now-extinct animals. Murujuga has been put forward as a UNESCO world heritage site, with strong indications it will be accepted as such. But the application has been referred back to the federal and WA governments with recommendations to stop building on the site, to stop the pollution and to prepare a decommissioning report.
