Glow-in-the-dark animal captured on camera for first time
A photographer from Down Under has become the first person to capture a photo of a glowing marsupial in the wild.
Aussie photographer Ben Alldridge submitted a photo as part of the 2025 Beaker Street Science Photography Prize. The photo was of a wild Eastern quoll, which is carnivorous marsupial that's native to Tasmania and exhibits biofluorescence.
Using invisible ultraviolet light, Alldridge captured the mammal glowing in the dark, and his photo is considered the first photographic evidence of a quoll exhibiting biofluorescence in its natural habitat, people.com reported.
'Where their fur is normally fawn or black, under certain wavelengths of light, they exhibit a process referred to as biofluorescence — like nature's version of a white shirt glowing at a disco,' Alldridge said, per the Daily Mail.
Smithsonian Magazine reported that several mammals across the globe, many of them nocturnal, are known to exhibit this phenomenon, including polar bears, moles, zebras, wombats, armadillo and more. Non-mammals such as corals, insects, spiders, fish, amphibians, reptiles and birds also exhibit the phenomenon, although the exact biological purpose of biofluorescence is still unknown.
Alldridge said he hopes his photos and studies into biofluorescence will help solve the mystery surrounding it.

'I'd say it's likely a messaging or identifying system similar to our fingerprints, but that is wild speculation at best,' he said, per the Daily Mail. 'For now, we will just say they like to party.'
Alldridge's photography will be considered as part of the ongoing research.
'The amount of light we waste illuminating space — both physical and now literal — is ridiculous, and in many cases is counterproductive to why the lights are installed to begin with,' Alldridge said.
Alldridge's photo is one of 12 finalist images to be exhibited at the Tasmanian Museum and Art Gallery from Aug. 6-31, as part of the Beaker Street Festival.

Cannabis And Psychedelics Seen As Effective For Eating Disorders, Study Finds
Anorexia Nervosa - Common Medical Marijuana Conditions for Qualifying Patients - use of the whole, ... More unprocessed marijuana plant or its basic extracts to treat symptoms of illness and other conditions. A new study has found that cannabis and psychedelics are perceived to be the most effective drugs that help alleviate eating disorder symptoms. A group of researchers from the University of Sydney has conducted a survey on over 6,000 people suffering from eight eating disorders, such as bulimia, anorexia, and binge-eating disorder, and found that most of them rely on cannabis and psychedelics to help alleviate their symptoms. Published on JAMA Network Open-Psychiatry this week, the study tried to understand which prescription and nonprescription drugs are used by people with eating disorders, and how they are associated with symptoms. To do so, participants, diagnosed with eating disorders and mainly from English-speaking countries, completed an online survey on recent prescribed and nonprescribed drug use, as well as perceived benefits and harms. Initially, 7,648 respondents were recruited; 6,612 completed demographics, and 5,123 finished the survey. The findings of the survey showed that overall, the best-rated drugs for eating disorder symptoms among respondents were psilocybin, cannabis, and lysergic acid diethylamide. For example, for respondents with anorexia, cannabis received the highest rating. When asked to identify their drug of choice for self-medicating eating disorder symptoms, the most popular drug among respondents was cannabis, but when normalized by number of users, fluoxetine, an antidepressant, ranked highest. Among 6,136 respondents, prescription psychotropics were rated highest for mental health. Psilocybin, LSD, and cannabis also received strong ratings. 'A striking outcome was the favorable self-reported ratings of psychedelics and cannabis for alleviating ED symptoms, eclipsing the ratings of commonly prescribed psychotropics,' the study reads. Can Cannabis Help Alleviate Eating Disorder Symptoms? The study also highlighted that daily cannabis users reported perceived benefits for their eating disorder symptoms. Researchers said that 'there is scant research around the use of cannabinoids in individuals with eating disorders apart from small trials supporting the efficacy of dronabinol, which is synthetic tetrahydrocannabinol, in those with anorexia nervosa.' They also added that cannabis may benefit people with restrictive and food-aversive eating disorders, like anorexia nervosa and avoidant/restrictive food intake disorder, 'by increasing the hedonic value of food.' This is in line with previous studies on the effects of cannabis on appetite. A study published last year showed that mediobasal hypothalamus (MBH), a region in the brain that regulates various physiological processes, controls increased appetite following cannabis use. In contrast, cannabis received poor ratings from people with bulimia and binge-eating disorder, likely because its appetite-stimulating effects can trigger or worsen binge-and-purge behaviors, thereby intensifying the symptoms of the eating disorder. Psilocybin and LSD were consistently rated highly across all diagnostic groups for their ability to improve eating disorder symptoms, enhance overall mental health, and be well tolerated. However, the study has several limitations. The survey primarily included participants from high-income, English-speaking countries with internet access. It may have also attracted people with eating disorders who are more inclined toward new ways to treat their eating disorder symptoms or have positive attitudes or prior positive experiences with drugs. Furthermore, diagnoses were based on self-report rather than formal clinical assessment, and comorbid conditions were not evaluated. Additionally, recall bias may have influenced participants' reports of drug use and symptoms. Therefore, because some findings are based on small sample sizes within specific diagnostic related to eating disorders and drug-use groups, the researchers highlighted that this study's results 'should be interpreted as exploratory rather than definitive.'

Plea to Aussie councils after common roadside problem exposed in photo
Australia's network of roads can be plain ugly, so what could be prettier than a local council planting a bed of pretty flowers across the surrounding nature strip? Unfortunately, experts have identified an often overlooked problem created beside one roundabout, just 6km west of Melbourne's CBD, where instead of local native plants, 'highly invasive' gazanias have been planted. Dr Ali Bajwa's Weed Science Group at La Trobe Institute for Sustainable Agriculture and Food has been investigating the impact of the species on the environment and agriculture, and he believes they are 'problematic'. The plant spiked in popularity in Australia during the 1950s and 1960s, but despite its known problems, it continues to be sold in nurseries and planted by councils. 'They spread quite rapidly. We've seen places where they've covered everything and replaced all of the remnant vegetation. They were introduced as ornamental plants, mainly grown in gardens and nature strips, and we believe that's where they've spread from,' he told Yahoo News Australia. Gazanias are known for their fierce growth, which ensures the species smothers native groundcovers and wildflowers, leading to a loss of native plant diversity. While its flowers and leaves are pretty to look at, they provide little habitat or food for native animals or insects. The plant can spread through garden waste, or via seeds or root systems when it's in the ground. Although some modern species have sterile seeds and this helps restrict its impact on the environment. Gazania is now a common sight along roadsides, particularly in Victoria and South Australia. When the species invades paddocks, farmers struggle to manage its spread, as standard herbicides are generally ineffective. Bajwa believes the 'horse has already bolted' when it comes to the invasion of gazania, but that doesn't give gardeners an excuse to plant more. The problem is clearly bigger than just one cluster, pictured on the side of the road in Footscray. 'Councils should be thinking of replacing them with more desirable species, like natives, which can grow well under the same conditions,' he said. Will the roadside gazanias be removed by council? Some local governments have already pulled them out to try and help the environment, but others are yet to do so. There doesn't appear to be any immediate plans to remove the gazanias or the invasive agapanthus growing in the roundabout in Footscray. Maribyrnong City Council, which manages the nature strip, did not respond directly to questions from Yahoo News about whether it was aware of the gazanias, why it was allowing them to flourish, or what it planned to do about the problem. 'Council uses a variety of native and non-native species in open space plantings to suit the character of different areas,' its CEO Celia Haddock said in a statement. 'Council does not plant declared noxious weeds and we continue to look for opportunities to prioritise native plants, and improve planting practices where suitable.' How councils can avoid spreading invasive plants To avoid the spread of more weeds into Australia's fragile environment, the Invasive Species Council (ISC) advises that local governments should opt for native plants. Speaking generally about the issue, spokesperson Imogen Ebsworth said there's simply not enough information available as to what has become invasive, or is likely to in the future. 'The result of that is that councils then sometimes find they've inadvertently planted an invasive species that then becomes a problem for them to manage on their own land, and also impacts others,' she told Yahoo. 'A way for councils to address this would be to really focus on plants that are natural to the local area, and are not invasive.' 🚨 Invasive species photographed destroying Aussie bush 🧪 Scientist's 'time capsule' in vault key to resurrecting Aussie species 🔎 Rare species with less than a thousand in the wild tracked down The ISC's solution to the problem is to approve national regulations that would prohibit the sale of invasive plants, taking the onus off councils and home gardeners to know what is problematic. 'We've got a situation where over 75 per cent of the invasive weeds we deal with have started their life as garden ornamentals, and a lot of them take 50 years or so for it to become clear that they're really invasive,' Ebsworth said. 'So we've got this huge time lapse gap where we've got over 30,000 introduced plants into Australia, most of them have not been assessed for whether they are weeds or could become weeds. So the information is really imperfect for decision makers. At the local council level, that means good intentions sometimes turn into invasive problems.'
