Over half the adult population in the UK and U.S. have gum disease from poor oral health. Typical treatments include mouthwash and, in severe cases, antibiotics. These treatments have side effects, such as dry mouth, the development of antimicrobial resistance, and increased blood pressure. Research has indicated that a molecule called nitrate, which is found ...
Remember the emotions you experienced around sadness that came with the last time you failed miserably at something? Or the last time you were so anxious about an upcoming event that you couldn’t concentrate for days? These types of emotions are unpleasant to experience and can even feel overwhelming. People often try to avoid them, ...
The Australian Navy is set to be transformed. On top of existing plans for nuclear submarines, the government announced a scheme for an “enhanced lethality surface combatant fleet,” including six new “optionally crewed” vessels. The advantages of these vessels, which can operate with or without a crew, are clear. They can operate longer, with more ...
The Australian continent is now geologically stable. But volcanic rocks, lava flows, and a contemporary landscape dotted with extinct volcanoes show this wasn’t always the case. Between 40 and 20 million years ago — during the Eocene to Miocene epochs — there was widespread volcano activity across eastern Australia. In places such as western Victoria ...
Australia can lay claim to two new native mammal species, which were discovered as part of our collaborative research published in the journal Molecular Ecology. Australia has some of the most unique biodiversity in the world, and our native mammals are particularly well known. For many, the iconic marsupials might be the first that come ...
Coles and Woolworths, the supermarket chains that together control almost two-thirds of the Australian grocery market, are facing unprecedented scrutiny. One recent inquiry, commissioned by the Australian Council of Trade Unions and led by former Australian Consumer and Competition Commission chair Allan Fels, found the pair engaged in unfair pricing practices; an ongoing Senate inquiry ...
When the first cane toads were brought from South America to Queensland in 1935, many of the parasites that troubled them were left behind. But deep inside the lungs of at least one of those pioneer toads lurked small nematode lungworms. Almost a century later, the toads are evolving and spreading across the Australian continent. ...
More than 380 million years ago, a sleek, air-breathing predatory fish patrolled the rivers of central Australia. Today, the sediments of those rivers are outcrops of red sandstone in the remote outback. Our new paper, published in the Journal of Vertebrate Paleontology, describes the fossils of this fish, which we have named Harajicadectes zhumini. Known ...
Artificial intelligence (AI) is seemingly everywhere. Currently, generative AI, in particular — tools like Midjourney, ChatGPT, Gemini (previously Bard), and others — is at the peak of hype. But as an academic discipline, this technology has been around for much longer than just the last couple of years. When it comes to real-world applications, many ...
Scientists have no reported evidence of the actual conditions in Hell, perhaps because no one has ever returned to tell the tale. Hell has been imagined as a supremely uncomfortable place, hot and hostile to bodily forms of human life, similar to a black hole. Thanks to a vast astronomical survey of the entire sky, ...
