Fossil discovery suggests sauropods didn't chew their food
What did scientists discover?
The group of scientists, lead by Curtin University in Australia, decided to study the fossilised stomach contents of a sauropod that was originally found in 2017 in the Australian state of Queensland.The dinosaur, a species called Diamantinasaurus matildae, was nicknamed Judy by researchers.What made this discovery unique, was that Judy's stomach contents had been well preserved, revealing for the first time in detail what it ate.The team's research found that the dinos snacked on a variety of plants from various heights above the ground, and that this helped their long-term success.Lead researcher Dr Stephen Poropat explained: "We also confirmed that sauropods were bulk-feeders – a method still used by herbivorous reptiles and birds today. "This means they would not have chewed their food, instead swallowing it whole and letting their digestive system do the rest of the work," he said. Therefore, sauropods would have relied on fermentation in its guts to process the food it ate.Dr Poropat added that food could have stayed in the dinosaur's digestive system for "up to two weeks" and that discovering what sauropods ate is critical to understanding their "impact on Earth's ecosystems" throughout that time.

Great Barrier Reef suffers worst coral decline on record
Parts of the Great Barrier Reef have suffered the largest annual decline in coral cover since records began nearly 40 years ago, according to a new and southern branches of the sprawling Australian reef both suffered their most widespread coral bleaching, the Australian Institute of Marine Science (AIMS) have been battered in recent months by tropical cyclones and outbreaks of crown-of-thorns starfish that feast on coral, but heat stress driven by climate change is the predominant reason, AIMS warns the habitat may reach a tipping point where coral cannot recover fast enough between catastrophic events and faces a "volatile" future. The 'underwater bushfire' cooking Australia's reefsA really simple guide to climate change AIMS surveyed the health of 124 coral reefs between August 2024 and May 2025. It has been performing surveys since dubbed the world's largest living structure, the Great Barrier Reef is a 2,300km (1,429-mile) expanse of tropical corals that houses a stunning array of biodiversity. Repeated bleaching events are turning vast swaths of once-vibrant coral is vital to the planet. Nicknamed the sea's architect, it builds vast structures that house an estimated 25% of all marine happens when coral gets stressed and turns white because the water it lives in is too hot. Stressed coral will probably die if it experiences temperatures 1C (1.8F) above its thermal limit for two months. If waters are 2C higher, it can survive around one warm tropical waters triggered widespread coral bleaching on the Great Barrier Reef in 2024 and in the first few months of 2025, the sixth such event since well as climate change, natural weather patterns like El Nino can also play a role in mass bleaching reef has "experienced unprecedented levels of heat stress, which caused the most spatially extensive and severe bleaching recorded to date," the report recovery could take years and was dependent on future coral reproduction and minimal environmental disturbance, according to the the latest AIMS survey results, the most affected coral species were the Acropora, which are susceptible to heat stress and a favoured food of the crown-of-thorns starfish."These corals are the fastest to grow and are the first to go," AIMS research lead Dr Mike Emslie told ABC News."The Great Barrier Reef is such a beautiful, iconic place, it's really, really worth fighting for. And if we can give it a chance, it's shown an inherent ability to recover," he said. There has been some success with the Australian government's crown-of-thorns starfish culling programme, which has killed over 50,000 starfish by injecting them with vinegar or ox bile."Due to crown-of-thorns starfish control activities, there were no potential, established, or severe outbreaks of crown-of-thorns starfish recorded on Central GBR reefs in 2025," the AIMS report creatures are native to the Great Barrier Reef and are capable of eating vast amounts of coral. But since the 1960s their numbers have increased significantly, with nutrients from land-based agriculture run-off regarded as the most likely cause. Richard Leck from the global environmental charity WWF said the report shows that the reef is an "ecosystem under incredible stress" and scientists are concerned about what happens when "the reef does not keep bouncing back the way it has," he told news agency said some coral reefs around the world are already beyond recovery, warning the Great Barrier Reef could suffer the same fate without ambitious and rapid climate Great Barrier Reef has been heritage-listed for over 40 years, but Unesco warns the Australian icon is "in danger" from warming seas and pollution.

Research into Australian skinks' resistance to snake venom could streamline design of antivenoms
Australian skinks have evolved the means to resist snake venom by shutting down their muscles, suggests new research which could help to inform future treatments for snakebites. Research led by the University of Queensland has found that multiple species of Australian skink have evolved venom resistance through changes to a critical muscle receptor. In other animals, the receptor is the target of venom neurotoxins, which cause rapid paralysis and death. Sign up: AU Breaking News email Study co-author Prof Bryan Fry, who leads UQ's adaptive biotoxicology lab, said that when venomous snakes arrived in Australia 25 to 30m years ago from Asia that skinks would have been their prey, resulting in evolutionary pressure to evolve venom resistance. 'What was fascinating was that with the kind of mutations that we documented in the Australian … skinks that gave rise to resistance are the kind of mutations that we've seen in other animals outside Australia,' Fry said. Mongooses, which feed on cobras, are one such example. The researchers showed that the Australian major skink, Bellatorias frerei had the same mutation that gave the honey badger its resistance to cobra venom. The researchers looked at 47 skink species and found that 13 of these were resistant to snake venom. Of these 13 species, some had multiple types of resistance, leading the researchers to discover that the skinks had developed independent mutations conferring resistance on 25 occasions. Fry said the researchers used tissue banks from museums across Australia rather than testing venom on live skinks. Study co-author and UQ researcher Dr Uthpala Chandrasekara said in a statement: 'We used synthetic peptides and receptor models to mimic what happens when venom enters an animal at the molecular level and the data was crystal clear, some of the modified receptors simply didn't respond at all.' 'It's fascinating to think that one tiny change in a protein can mean the difference between life and death when facing a highly venomous predator. Sign up to Breaking News Australia Get the most important news as it breaks after newsletter promotion 'The more we learn about how venom resistance works in nature, the more tools we have for the design of novel antivenoms.' Dr Andrew Amey, collection manager of amphibians, reptiles and herpetology at Queensland Museum, who was not involved in the research, said that there were more than 470 currently recognised species of Australian skink, with more being discovered all the time – with little known about them. 'It is great to see research looking into how they deal with such an important predator that just might tell us more about how we can manage the effects of snakebite ourselves,' Amey said. The study was published in the International Journal of Molecular Sciences.

Australian researchers discover two invasive weeds have the potential to be burned as biofuel
Two invasive weed species could contribute to a creative solution to Australia's energy transition – as ingredients for clean, renewable fuel. Researchers at the University of Queensland found Brazilian nightshade and climbing asparagus – both aggressive vine species – can be converted into biomass pellets. The June research, highlighted this week by UQ's Queensland Alliance for Agriculture and Food Innovation, assessed more than 20 weed species for their potential use as fuel. The process involves compressing plant material into small pellets similar in appearance to pet food pellets, which can be used as fuel in residential or industrial heating systems, or electricity generation. The densified organic matter can be used as solid fuel to generate energy, reducing reliance on fossil fuels such as coal. 'We try to get the right mix of these ingredients so the pellets burn well and safely,' said lead researcher Dr Bruno Rafael de Almeida Moreira. 'We're trying to discover something useful for our community and environment.' Different plant materials have to be mixed and tailored in specific ways, Moreira explained. Too much moisture or ash-producing minerals in pellets can damage heaters or stoves, create dust when handled and release toxic smoke or gases. Pelletising also helps reduce production costs and emissions, because pellets are easier to move and store more energy per volume than using the raw material, Moreira said. He noted the rapid growth of the global solid biofuels market, especially in Canada, the US, and Europe. Traditionally, solid biofuels come from forest wood sources. In Australia, however, wood pellets made from native forests are not classified as renewable. Recycled timber and wood waste can be used, but only if approved by the federal Clean Energy Regulator, prompting a search for alternatives. Moreira said Australia's diverse biomass sources present a unique opportunity for it to lead the way in sustainable bioenergy production. Study co-author and AgriSustain Lab leader, associate prof Sudhir Yadav, said the new research could support efforts to reduce agriculture's carbon footprint, while boosting the bioenergy sector. 'Agencies like the Australian Renewable Energy Agency have predicted bioenergy will supply 20% of national energy demand by 2050,' Yadav said. 'It's an optimistic but achievable target and a lot of research is required to bridge that gap.' Moreira noted previous estimates putting biomass at just 0.3% of Australia's renewable energy mix. He agreed the leap to 20% was ambitious – but possible, with 'sustained research and innovation'. The researchers said the study is ongoing, with more weed species to be tested. But supply remains a challenge, even for the most prolific weeds. 'Environmental weeds have a limit,' Yadav said. 'We're also thinking about other potential sources of biomass, like green waste collected by councils and households and even some broad acre crops like sorghum.' Microbiologist Dr Ian Paulsen, a distinguished professor at Macquarie University and director of the Australian Research Council Centre of Excellence in synthetic biology, who was not involved with the study, said it builds existing research on converting plant matter into fuel. E10 fuel for cars contains ethanol made from crops such as corn in the US, or wheat, barley or sugarcane in Australia, Paulsen said. 'In Brazil, previously, they've run planes of flown on aviation fuel made from getting yeast to turn sugarcane into long chain hydrocarbons.' Sign up to Breaking News Australia Get the most important news as it breaks after newsletter promotion But Paulsen said large-scale biofuel production was currently not economically viable without significant government subsidies, or a sharp rise in petrochemical prices. 'It's technologically feasible; the real problem is that it's hard to be cost-competitive compared to the fossil fuel industry,' he said, noting the latter benefits from over a century of global subsidies and highly efficient infrastructure. Paulsen said proposing invasive weeds as fuel posed logistical concerns, particularly in terms of the difficulty of harvesting large volumes of scattered biomass without damaging ecosystems. Moreira said expanding the diversity of bioenergy sources was critical to achieving net zero targets. He emphasised the importance of increasing funding and interdisciplinary collaboration in advancing renewable energy solutions, calling it 'an opportunity for us to come together and brainstorm ideas, exchange knowledge across the country, around the world'. 'We have to be sure about the diversification of this space … we cannot rely only on wind or solar panels,' he said. 'It's about ensuring clean energy for all people in the future.' Flinders University's Vincent Bulone is a professor in glycoscience, the study of glycans, or sugars, and part of the search for alternative sources of energy and development of new materials. He said the study highlighted an 'emerging and promising area of research' for sustainability and land management in Australia. He echoed, however, that implementing it would require strategic investment in the appropriate technology, infrastructure and policy. Bulone said Australia's regional diversity demanded a 'distributed bioenergy model' tailored to local biomass availability – in this case, invasive weeds in Queensland – industry needs and community energy goals, especially in remote and Indigenous communities. 'Pelletising invasive weeds could become one of the components of Australia's renewable energy strategy, particularly in rural and remote areas where weed prevalence and energy needs are high.' It is not a stand-alone solution, but represents a 'valuable component of a broader, diversified bioenergy strategy,' he said.
