Scientists baffled after observing unusual behavior in vulnerable bird species: 'Their farming actions play an important role'
But scientists recently discovered that this bird is more than a master impressionist with a knack for shaking its tail feather — it's also a forest farmer with a surprisingly big impact.
As reported by Earth.com, researchers at La Trobe University recently published findings in the Journal of Animal Ecology that reveal the lyrebird actively cultivates its own food supply by raking through the forest floor. With this behavior, it plays a key role in maintaining biodiversity, offsetting what it eats by continuously replenishing the food source — and even preventing forest fires.
By observing the lyrebird's natural foraging technique and recreating it in a simulation, researchers learned just how much the bird was altering the environment and helping its favorite foods — invertebrates like worms, spiders, and centipedes — thrive.
According to the study's lead author, Alex Maisey, "Lyrebirds set up the perfect home for their prey, creating conditions with more food resources and effectively fattening them up before eating them."
In an article for The Conversation, the authors added: "The interaction between lyrebirds and invertebrates has wide benefits for forests. Invertebrates help cycle nutrients and disperse seeds. They also provide food for many birds, small mammals and reptiles."
Not only are lyrebirds enriching habitats for other creatures by spreading nutrients, but they're also helping prevent bushfires — a natural part of Australia's ecosystem that has become more frequent and intense due to rising global temperatures.
The researchers found lyrebirds can move around a whopping 155 tonnes (171 tons) of organic material per hectare, making sure it breaks down and enriches the soil. "Lyrebirds are widespread and active across millions of hectares of forest. Their farming actions play an important role in maintaining forest biodiversity," said Dr. Maisey.
By recognizing lyrebirds as "ecosystem engineers," conservationists hope to better protect their habitat — and in turn, protect the forests they help maintain.
These findings show just how vital local biodiversity is — and how much we rely on native species to maintain balance in the natural world. If you're feeling inspired by this feathered forest farmer, you can take local action to support native wildlife and sustainable ecosystems in your own community.

As Dr. Maisey told the British Ecological Society: "Without the lyrebird, these forests would be vastly different — poorer in biodiversity and less resilient to disturbances like fire. Understanding and protecting these natural ecosystem engineers is crucial for maintaining the health of our forests for future generations."

Doctor Raises Concerns Over Medical Cannabis Use With Cancer Treatment
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Despite its growing popularity among cancer patients for managing symptoms like nausea, pain and reduced appetite, a new study has warned that the use of medicinal cannabis could make immunotherapy less effective. This is the warning of Australian medical cannabis advocate Dr. Ben Jansen, whose newly-published review paper poses the question: "Are cannabinoids with cancer immunotherapy contributing to early death?" "As both a physician involved in the medicinal cannabis industry and an advocate for patient care, I find the discussion and patient informed consent around this interaction critical," Jansen wrote in his study. "Three key studies on this topic offer preliminary data suggesting a potential reduction in immunotherapy efficacy from cannabis use," he continued. "Though the results remain limited and controversial, warranting caution and additional research." Medical marijuana over official looking subscription document.

It compared those on nivolumab alone (89 patients) and those on both nivolumab and cannabis (51 patients). The findings, Jansen noted, showed a significantly lower treatment response rate in patients using cannabis than in those on just nivolumab (15.9 vs. 37.5 percent.) The analysis excluded patients with advanced disease with survival of less than two months. "This suggests that patients using cannabis were approximately three times more likely to have a poor response to immunotherapy. Notably, cannabis use did not significantly impact progression-free survival or overall survival," Jansen wrote. Building on this, the second study compared 34 patients prescribed both immunotherapy and cannabis with 68 patients receiving the cancer treatment alone. That study found that tumors tended to take less than three-and-a-half months to grow or spread in the patients taking cannabis, as compared to more than a year for patients on immunotherapy alone. It also found the median overall survival time for cannabis users was 6.4 months compared to 28.5 months for non-users. A colourful illustration representing immune cells and white blood cells.

Jansen added: "Factors such as smoking and other lifestyle elements, which heavily influence cancer risk and treatment outcomes, should be carefully considered when assessing cannabis' role in immunotherapy efficacy and cancer progression, and when interpreting the studies." The third study looked at 105 patients with tumors developing in solid organs—e.g. the breast, lung or prostate—receiving immune checkpoint inhibitors, and cannabis use primarily in the form of prescribed dronabinol. (Immune checkpoint inhibitors are a form of immunotherapy treatment that works by blocking proteins that prevent the immune system from attacking cancer cells.) Cannabis use was associated with significantly worse outcomes in patients receiving immunotherapy, including a shorter median overall survival time (6.7 vs 17.3 months), a reduced progression-free survival tune (4.8 vs 9.7 months) and a markedly lower disease control rate (10.7 percent vs 37.7 percent) compared with non-users. "Notably, these negative outcomes were most evident in white patients, raising the possibility of ethnicity-related pharmacogenetic variability in cannabinoid metabolism or immune response," Jansen wrote. Other potentially important factors like performance status, comorbidities and socio-economic status may have also been unaccounted for, and though tobacco was more common among cannabis users, it may still have influenced outcomes.

Past research, Jansen notes, has found that cannabis can suppress the immune system through its active compounds: CBD, THC and other minor cannabinoids. At the same time, however, studies undertaken both in vitro and in living organisms have suggested that cannabinoids can both kill cancer cells and stop from spreading. "These findings hold particular relevance for patients considering, or currently using, medical cannabis during immunotherapy," the doctor said. "As medical practitioners, we must weigh the benefits of cannabis in managing cancer-related symptoms (such as pain, nausea and anorexia) against its potential to compromise treatment efficacy." "While cancer has a promising role in supportive cancer care, these early findings support careful consideration when patients are concurrently undergoing immunotherapy." Jansen emphasized how important it is that clinicians ensure patients are well informed of potential interactions, particularly until we have a clearer understanding of the situation, and has called for more thorough research and trials. "Future studies should aim to control for variables such as cancer type, cannabis dosage, socio-economic status and patient lifestyle factors, particularly tobacco use, which may confound results," he concluded.

Water Utilities Are Using Solar Panels to Cut Evaporation Losses
Every year, about 1,400 gigaliters of water evaporates from dams and reservoirs across arid Australia, enough to fill Sydney Harbour three times, according to researchers at Deakin University. To reduce this loss, Australian utilities are turning to floating solar installations on lakes and reservoirs. Covering and cooling a large part of the surface of bodies of water with panels reduces evaporation, while also generating electricity. In a country where climate change is making conditions even hotter and drier, and where fresh water is scarce, solutions like this are becoming more attractive.

Aussie researchers warn of 'unintended' Starlink issue amid growing adoption
Australian researchers are highlighting a frustrating problem in the skies above us as the growing number of satellites providing high-speed internet connectivity are having unintended consequences, potentially hindering our ability to understand the universe. New research has shown how the satellite technology of private companies like Starlink — increasingly relied upon by Aussies — is inadvertently interfering with the ability of researchers to study the depths of the cosmos. The warning comes after astronomers in Western Australia undertook the world's biggest study of low frequency satellite radio emissions. And it comes at a particularly critical time as construction continues in the state on what will become the world's largest radio telescope — a massive project known as the Square Kilometre Array (SKA) that promises to help answer some of the biggest questions in the field. "It's going to be the largest radio telescope of all time, and it's looking for very faint signals from the early universe," PhD candidate and study lead Dylan Grigg told Yahoo News Australia. "And so what we wanted to do was understand the prevalence of satellites at the frequencies that the Square Kilometre Array would be looking over." The researchers essentially took an image of the sky every two seconds for about a month, totalling some 76 million images. "We detected a lot of satellites in the images. The overwhelming majority of those were Starlink satellites," Grigg said. "And what we found was that they're not transmitting at their designated downlink frequency, there's some emissions coming from some electronics on board the satellites." At some frequencies about a third of the images were ultimately impacted, and the disturbance was observed at frequencies that are set aside for radio astronomy. For instance, 703 satellites were identified at 150.8 MHz, which is meant to be protected for radio astronomy. While Starlink, which had more than 7,000 satellites in low-Earth orbit during the period when the study was carried out, isn't doing anything wrong, the devices "just happen to be [emitting] over frequencies that radio astronomers will want to be conducting science with the SKA," Grigg said. Industry and academia clash as space fills up Australians in regional areas have increasingly adopted Starlink's internet services, with the company previously saying it has more than 200,000 local subscribers. While many residents in the bush rely on it for fast home internet, caravan travellers also take it on the road to stay connected at campgrounds and remote spots around the country. The WA astronomers don't dispute the boon the service provides, but hope the research will help lead to solutions to ensure scientists and private business can operate in harmony. "We've had a dialogue ongoing with SpaceX about it. They've made good mitigations in the past for optical astronomy, like they've painted their satellites with a darker paint, and they've put visors up on them. So we're hoping that by doing a study like this, we can continue the dialogue with them and hopefully see if we can get them to make some similar mitigations for radio as well." With Amazon launching satellites in a bid to compete with Starlink, and a raft of other companies launching their own satellites for various networks including emerging direct to mobile technology, low-Earth orbit is becoming an increasingly busy place. "Starlink isn't the only satellite network, but it is by far the biggest and its emissions are now increasingly prominent in our data," Executive Director of the Curtin Institute of Radio Astronomy and study co-author Steven Tingay said in a statement. New SKA project puts astronomy on 'edge of golden era' Being assembled at more than 500 sites in the Australian outback and due to be finished by the end of the decade, the SKA will be the largest and most sensitive radio telescope on the planet. The international project has been likened to one of the world's biggest science experiments that will be able to peer back into the earliest time of the universe. "It'll be a game-changer," Grigg told Yahoo News. Professor Tingay said it will help answer some of the most important questions we have. "We're standing on the edge of a golden era where the SKA will help answer the biggest questions in science: how the first stars formed, what dark matter is and even test Einstein's theories," he said. "But it needs radio silence to succeed. We recognise the deep benefits of global connectivity but we need balance, and that starts with an understanding of the problem, which is the goal of our work." Their research highlighting the "unintended Starlink broadband emission on radio astronomy" in the SKA bands was published this month in the journal Astronomy and Astrophysics.
