A global database documenting the location of critical habitats for sharks, rays, and chimeras has recently expanded to include Australia, with years of extensive research by Charles Darwin University (CDU) contributing to this crucial digital record. [...]
More than 7.5 million people immerse themselves in lakes, rivers, seas and lidos every year in the UK. But getting in the water means getting in pollution too for most outdoor swimmers. Raw sewage was discharged into UK waters for 4.7 million hours during 2024. But sewage is only part of the water pollution problem. Rain washing into rivers and streams contains fertilizers, pesticides and animal waste from farmlands, forever chemicals from car tires, plus drugs from our own bodies. Industry deregulation and privatization have produced a water crisis. [...]
The performance horse industry had a problem: Some of their most beloved and sought-after mares simply couldn't have foals safely. To make matters more complicated, in vitro fertilization (IVF) had not yet produced a healthy equine embryo, despite years of success in other species like cattle. [...]
In the middle of the old-growth forests of Congaree National Park in South Carolina, fireflies put on an otherworldly display every May. Thousands of male insects belonging to the species Photuris frontalis flash together at the same time and follow the exact same pattern—a synchronous light show you can see only in few places in the United States. [...]
Wet wipes conveniently clean and sanitize soiled surfaces and skin. Because some labels do not clearly indicate how consumers should dispose of them, these small cloths are often flushed down the toilet and released by sewage plants into waterways. Now, researchers report in ACS ES&T Water that some of these wipes break down into plastic fibers, or microplastics, that could harm aquatic life. [...]
Dragonfly integration and testing—the activities involved in assembling the mission's rotorcraft lander and testing it for the rigors of launch and extreme conditions of space—is officially underway in clean rooms and control rooms at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. [...]
Wildlife populations that become small and isolated, often due to habitat loss, inevitably experience inbreeding which can lead to the loss of fitness and eventual extinction. One solution is to perform a genetic rescue: a management intervention where new blood is brought in by introducing outsiders to a population to reduce inbreeding and restore diversity. But how do researchers know the inbreeding problem has been solved? [...]
Multiferroic metals are materials that exhibit both electric polarization and magnetic order in the same crystal—a state known as multiferroicity. Because these properties coexist, they can interact through magnetoelectric (ME) coupling, allowing electric fields to influence magnetism. [...]
MLIP calculations successfully identify suitable dopants for a novel photocatalytic material, report researchers from the Institute of Science Tokyo. As demonstrated in their study, published in the Journal of the American Chemical Society, a materials informatics approach could predict which ions can be stably introduced into orthorhombic Sn3O4, a promising and recently discovered photocatalytic tin oxide. [...]
An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger discovery. In November 2024, the LIGO-Virgo-KAGRA observatories detected gravitational waves from a binary black hole merger, designated S241125n. Remarkably, just seconds later, satellites recorded a short gamma-ray burst (GRB) from the same region of the sky. [...]
The customer is always right. It's the first rule of customer service, one that often means "I'm sorry" is the de facto response if mistakes are made. But a new study published in the Journal of Consumer Research indicates that the age-old maxim might not hold water. In fact, apologies might actually make things worse, both for businesses and customers. [...]
A new LMU study shows how proteins function reliably even without a stable 3D structure—and the crucial importance not only of short sequence motifs, but also of chemical characteristics. [...]
A tropical insect has been found to change color from vivid hot pink to green within a fortnight, which scientists believe may mimic the young leaves of rainforest plants. The findings, published this week in the journal Ecology, focuses on Arota festae, a leaf-masquerading katydid also known as a "bush cricket," native to Panama, Colombia and Suriname. [...]
A research team associated with the European project DEATHREVOL has published a study in the journal Scientific Reports that proposes new analytical tools to better understand how fractures of the human skull occur and how these injuries can be interpreted in order to distinguish between accidental trauma and trauma resulting from interpersonal violence. The study involved researchers from Centro Nacional de Investigación sobre Evolución Humana (CENIEH) and from the University of Burgos and Rey Juan Carlos University (Madrid). [...]
Scientists from the National University of Singapore (NUS) have developed a biochemical technique that captures fleeting "handshakes" between newly made proteins and the cellular helpers. These short interactions are important because they can determine whether a protein turns out healthy and useful or is faulty and in need of removal. The research has been published in the journal Molecular Cell. [...]
It's long been assumed that for an organism to learn, remember or draw conclusions, it needs a brain. But mounting evidence, including a recent Cognitive Science study, challenges that assumption, suggesting that neurons might not be necessary for complex information processing. [...]
Two locations have been identified as the most likely entry points into Australia for a disease that poses a huge risk to the beef and dairy industries. A University of Queensland-led team has built the first geospatial model to map where insects carrying lumpy skin disease virus (LSDV) could arrive either blown by strong wind or carried on ships. [...]
An international team of researchers has achieved a breakthrough in the production of doxorubicin, a vital chemotherapy agent. The study identifies and resolves molecular "bottlenecks" that have limited the natural production of this drug for over 50 years. The research is published in Nature Communications. [...]
There is a near-infinite number of material candidates out there—and simply not enough time to hunker down in the lab and test them all. Thankfully, researchers have a variety of tools (such as AI) at their disposal to streamline what would otherwise be a time-consuming process of trial-and-error. [...]
Engineers at Duke University have demonstrated a technique that uses microbubbles and ultrasound to help relatively large cancer drugs enter tumor cells and cause them to self-destruct. Dubbed "Sonoporation-assisted Precise Intracellular Nanodelivery"—or SonoPIN for short—the technology caused 50% of targeted cancer cells in a benchtop experiment to self-destruct, while leaving 99% of non-targeted cells healthy. The results show promise for precisely delivering a wide variety of large-molecule therapeutics to cells with few off-target effects. The research appears in Proceedings of the National Academy of Sciences. [...]
Urban parks are a vital component of urban ecosystems and provide distinctive habitats for soil microorganisms. Yet scientists have questioned whether—and how—the functional diversity and evolutionary potential of microbial communities are being reshaped by rapid urbanization. [...]
In reptiles, a simple temperature change can determine whether an egg develops into a male or female. This process is formally known as temperature-dependent sex determination (TSD), in which the sex of an embryo is determined by the temperature it experiences during a specific window of development known as the temperature-sensitive period. For example, in American alligators, incubation at around 30 °C typically produces females, while temperatures near 33 °C produce males, although extremely high temperatures can again result in females. [...]
In the journal Science Advances, scientists in Sweden and the U.S. report the first-ever direct observation of a type of short-lived molecule that has shaped decades of thinking in atmospheric chemistry, combustion research and biomedical science. [...]
Astronomers have found an exoplanet that could serve as a benchmark in future studies. It's a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a benchmark for understanding other M-dwarf exoplanets and their atmospheres. According to the authors of a new study, this new exoplanet could serve as "a reference system for highly irradiated rocky planets." [...]
The tiny Amazon molly (Poecilia formosa) has always fascinated researchers because, according to the rules of evolution, it shouldn't have survived as a species, let alone thrive as a species for over 100,000 years. Using advanced genetic mapping and comparison techniques to track how the Amazon molly's DNA has changed over time, a new study set out to uncover the genetic secrets behind this apparent rebellion against evolutionary theory. [...]
Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum magnetic resonance, Osaka Metropolitan University researchers have discovered how shifting internal electric fields dictate whether these devices shine brightly or dimly. Their study is published in the journal Advanced Optical Materials. [...]
To survive in areas where it is difficult to photosynthesize, some organisms adopt unique strategies. Osaka Metropolitan University researchers have found that a freshwater alga captures far-red light as an additional energy source by arranging ordinary chlorophyll in an extraordinary way. The findings were published in the Journal of the American Chemical Society. [...]
The Miocene, beginning approximately 23 million years ago, represents a canonical "warm-Earth" interval characterized by elevated atmospheric CO2 and a warmer global climate. The El Niño–Southern Oscillation (ENSO), as a leading mode of interannual climate variability, exerts pronounced influences on global precipitation patterns and the occurrence of climate extremes. Investigating ocean–atmosphere variability under Miocene-like high-CO2 background states therefore provides a valuable framework for evaluating climate-model performance in warm climates and for informing expectations of ENSO behavior under continued anthropogenic warming. [...]
The episode of extreme rainfall that affected the east of the Iberian Peninsula at the end of October 2024 left a devastating mark on the province of Valencia. In some areas, such as Turís, more than 700 liters per square meter were recorded in 24 hours; in other words, in just one day, more water fell than the average rainfall in mainland Spain in an entire year. This caused catastrophic flooding and the disaster resulted in more than 200 deaths, as well as billions of euros in damage. [...]
If you were a bee, how would you choose a flower to land on? You might go to the most beautiful one, as pollination biologists have long suggested that flowers with striking colors attract pollinators more easily. Or perhaps, as other studies indicate, you might go where other bees are feeding, like seeing a long line outside a restaurant and thinking it must be worth the wait. [...]
