Australians don't need an economist to tell them they're hurting at the petrol pump. They feel it every time they pull into a service station, every time they rethink a planned holiday, or every time they've had to squeeze another household bill to fill the tank. But the cost of rising petrol prices isn't only financial. It's emotional, social, and psychological too. [...]
On a calm summer's morning in southern Australia, the water can look deceptively clear, until you see thousands of gelatinous shapes washing ashore. In January, thousands of pink lion's mane jellyfish washed into Port Phillip Bay, prompting beach warnings and startling swimmers more accustomed to cold water than the shock of stinging tentacles. [...]
Some 39 Australian mammals have gone extinct since Australia was colonized in 1788. [...]
Using new genetic markers, fruit breeders can now tell whether grapes will be seedless and self-pollinating even years before vines bear fruit. The approach will save time and resources in the pursuit of creating flavorful new grape varieties, including the major challenge of developing seedless muscadines on self-pollinating vines. A paper on this work appears in Journal of the American Society for Horticultural Sciences. [...]
More than 3,000 fish species have been caught in bottom trawls, with estimates suggesting the true number could be nearly double, according to the world's first global inventory. [...]
When a drought turns into an urban water crisis, a city's first step is often to limit lawn watering and launch a campaign to encourage everyone to conserve. It might raise water-use rates or offer incentives for installing low-flow devices. [...]
A study published in Cell Research advances a central idea in stem cell biology by identifying a checkpoint that controls the identity of many different types of stem cells across developmental stages. For nearly two decades, scientists have understood that stem cell self-renewal depends on blocking differentiation signals—a concept described in earlier work, including Qi-Long Ying and Austin Smith's 2008 Nature paper titled "The ground state of embryonic stem cell self-renewal." [...]
Online comments can shape how social media content about politics is perceived, even when people's opinions are hard to change, a new study shows. The new research suggests that while attitudes may be stable, the way people interpret political messages can still shift depending on the surrounding conversation online. Engaging with problematic content can make a difference. [...]
A shutdown of the Atlantic Meridional Overturning Circulation (AMOC) could trigger a substantial release of stored ocean carbon into the atmosphere over hundreds of years, according to a new study that simulated such a collapse under stable climate conditions. This would add 0.2°C of extra global warming. The new paper from researchers at the Potsdam Institute for Climate Impact Research (PIK), published in Communications Earth & Environment, highlights the AMOC's role as a key regulator of the global climate. [...]
Sustainability has become something of a buzzword over the years. From the clothes we wear and the energy that powers our homes to the way we live our lives, the idea of sustainable production and consumption has become commonplace. [...]
Tropical rainforests are home to almost two-thirds of all vertebrate species and three-quarters of all tree species: they are the most species-rich terrestrial ecosystem on Earth. However, over half of these diverse rainforests have already been cleared, and their area continues to decline drastically, primarily for agricultural purposes. Is there a chance of regeneration, and can not only trees but also the unique diversity of thousands of animal species return to cleared areas? [...]
Excavation of a council house at the major Lowland Maya center of Ucanal, Guatemala, reveals how the public gained some influence over Maya politics more than 1,000 years ago. These colonnaded, open halls were likely council houses, where political leaders met to deliberate on governmental decisions. The open structures contrast with previous Classic period palaces, where "divine" rulers made political decisions in more private spaces. This shows the increasing importance of consensus-based politics from c. 810–950 AD onward. [...]
Musicians around the world agree on one thing: streaming platforms are essential for their careers. Most also agree on another: they don't pay enough. A new report from the Oxford Internet Institute and the University of Groningen captures this contradiction across five countries—Brazil, Chile, the Netherlands, Nigeria and South Korea. [...]
Every day, fish caught in oceans and seas around the world pass through a long journey before reaching supermarkets, restaurants, and home kitchens. Along the way, their freshness steadily declines, often in ways that are difficult to detect. Now imagine being able to measure how fresh a fish is at any point along this journey. Researchers at Hokkaido University have developed a mathematical model that can do exactly this. The latest development could help reduce food waste and improve seafood quality. [...]
From space, Earth's populated areas glow on the otherwise "black marble" of the planet at night. For decades, scientists assumed this glow was steadily increasing as the world developed. However, a new study published in Nature flips this narrative. [...]
An international team of researchers, led by scientists from the University of California, Irvine, has demonstrated a fundamentally new way to make silicon emit light—overcoming one of the most persistent limitations in modern electronics and photonics. In their work appearing in Nano Letters, the scientists show that silicon, long considered an inefficient light emitter due to its indirect bandgap, can be transformed into a bright, broadband source. The researchers produced emissions from silicon in its conventional bulk form, without modification to its composition or structure. Instead, the breakthrough comes from modifying the properties of light itself. [...]
A specific protein controls mRNA transport in fungi and distinguishes important from unimportant binding sites in the transported mRNAs. Researchers from Würzburg and Düsseldorf have discovered this mechanism. [...]
Earlier this year, I published a paper on the ethics of researching military populations. The core argument was straightforward: the standard rules researchers follow to protect participants—for example, informed consent and voluntary participation—don't work the same in an institution built on hierarchy and obedience. [...]
A study of nearly 200,000 Amazon reviews shows that the usefulness of online product reviews depends not only on what is said, but on how the information is structured. The researchers, from the Universities of Cambridge and Queensland, studied Amazon reviews for products ranging from clothing to food to electronics. They found that how the information is organized matters as much as what is said, and that different review structures are more or less helpful, depending on how highly the reviewer has rated the product. [...]
Undergraduate students at Penn State Brandywine developed an environmentally friendly and easy method to synthesize compounds from plant-derived molecules for potential use in therapeutics. Their work, conducted under the supervision of Penn State Brandywine Assistant Professor of Chemistry Anna Sigmon, was published in a special issue of the journal ACS Omega titled "Undergraduate Research as the Stimulus for Scientific Progress in the U.S." [...]
A 93-strong international expedition team has been exploring the northwestern Weddell Sea in the Antarctic on board the Alfred Wegener Institute's icebreaker Polarstern since February 8, 2026. In this key region for global ocean currents, the focus has been on the outflow of ice and water from the Larsen Ice Shelf and the astonishing sea ice retreat of recent years. When the research work had to be interrupted due to rough weather conditions in order to seek shelter in the lee of Joinville Island, the scientists and ship's crew were surprised by the sudden appearance of an island that had previously only been marked as a danger zone on the available nautical charts. [...]
By analyzing DNA of ancient skeletons at a Neolithic burial site near Paris, an international team of researchers has uncovered evidence of a dramatic population replacement 5,000 years ago. The findings indicate that the population collapse known as the "Neolithic decline" was a far-reaching phenomenon. [...]
A study by researchers at the SUNY College of Environmental Science and Forestry indicates that if lichen continues to decline across the Arctic, caribou populations could struggle to survive the winter. [...]
A trio of researchers from the University of São Paulo (USP) and São Paulo State University (UNESP) in Brazil has developed a method to obtain an enzyme from a fungus cultivated in agricultural waste that promotes cellulose pulp bleaching, an important paper production process. Their study is published in the journal BioResources. [...]
Sharing habitat with livestock is changing elephants' gut bacteria in ways that could be harmful to their health, according to new research conducted by San Diego Zoo Wildlife Alliance in collaboration with Save the Elephants. The study, appearing in Royal Society Open Science, tracked known individual elephants in the Samburu and Buffalo Springs National Reserves in Northern Kenya and found that when livestock numbers increased in the reserves, the elephants' gut microbiomes shifted significantly. Microbes commonly found in livestock became more abundant in elephant guts, while beneficial microbes decreased. [...]
Taking inspiration from how mussels and mistletoe plants build natural fibers and adhesives, researchers at McGill University have developed a new way to manufacture complex materials that could offer a more environmentally sustainable alternative to conventional plastics and glues. The findings are published in the journal Advanced Materials. [...]
A new study reveals that most fatal landslides occur in human-transformed environments. Conducted by an international team of researchers from the University of Vienna, Ankara University, Istanbul Technical University, Bursa Uludag University, and the GFZ Helmholtz Centre for Geosciences, the study provides a global overview of how human pressure modulates landslide occurrences. The paper is published in the journal Science Advances. [...]
You have probably never heard the term "crimefluencer." These are members of decentralized online crime networks who take crime content and amplify it to build notoriety and status in their online communities. [...]
For gardeners who love colorful, tidy flower beds, helping pollinators doesn't have to mean going fully wild. A new study from plant biologists at Northwestern University and the Chicago Botanic Garden found that some cultivated plants—bred for their vibrant blooms, compact forms and visually appealing uniformity—can still provide meaningful support for bees, butterflies and other pollinators. [...]
Glaciers in High Mountain Asia—a region encompassing the Tibetan Plateau and its surrounding mountain ranges—are shrinking rapidly, endangering water resources for millions of people, suggests a new study. Using satellite data from NASA's GRACE missions, results show that these extensive glacier systems, often called the "water towers of Asia," experienced significant losses in mass between 2002 and 2023. These findings reveal that if the extreme conditions that led to this decline continue, enhanced glacier melt could intensify short-term flood risks and substantially reduce long-term meltwater availability. The researchers say the findings underscore the need for reduced greenhouse gas emissions to stave off glacier melt and preserve a larger fraction of the region's cryospheric water storage. [...]
