Published Even the simplest marine organisms tend to be individualistic



Sport junkie or couch potato? Always on time or often late? The animal kingdom, too, is home to a range of personalities, each with its own lifestyle. Biologists report on a surprising discovery: even simple marine polychaete worms shape their day-to-day lives on the basis of highly individual rhythms. This diversity is of interest not just for the future of species and populations in a changing environment, but also for medicine.
Published Leptanilla voldemort, a ghostly slender new ant species from the dark depths of the underground



In the sun-scorched Pilbara region of north-western Australia, scientists have unearthed a mysterious creature from the shadows -- a new ant species called Leptanilla voldemort.
Published Brightest gamma-ray burst of all time came from the collapse of a massive star



In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The team also looked for signatures of heavy elements like gold and platinum in the supernova. They found no evidence of such elements, deepening the mystery of their origins.
Published Stellar winds of three sun-like stars detected for the first time



An international research team has for the first time directly detected stellar winds from three Sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the mass loss rate of the stars via their stellar winds.
Published Beautiful nebula, violent history: Clash of stars solves stellar mystery



When astronomers looked at a stellar pair at the heart of a stunning cloud of gas and dust, they were in for a surprise. Star pairs are typically very similar, like twins, but in HD 148937, one star appears younger and, unlike the other, is magnetic. New data suggest there were originally three stars in the system, until two of them clashed and merged. This violent event created the surrounding cloud and forever altered the system's fate.
Published Trapped in the middle: Billiards with memory



Adding one simple rule to an idealized game of billiards leads to a wealth of intriguing mathematical questions, as well as applications in the physics of living organisms. Researchers are discovering the fascinating dynamics of billiards with memory.
Published Star Trek's Holodeck recreated using ChatGPT and video game assets



Star Trek's Holodeck is no longer just science fiction. Using AI, engineers have created a tool that can generate 3D environments, prompted by everyday language.
Published Breakthrough promises secure quantum computing at home



The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
Published Twinkle twinkle baby star, 'sneezes' tell us how you are



Researchers have found that baby stars discharge plumes of gas, dust, and magnetic flux from their protostellar disk. The protostellar disk that surrounds developing stars are constantly penetrated by magnetic flux, and if too much magnetic flux remained, the resulting object would generate a magnetic field stronger than any observed protostar. These newly discovered discharges of magnetic flux, or 'sneezes' as the researchers describes them, may be a vital step in proper star formation.
Published Oxidant pollutant ozone removes mating barriers between fly species



Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.
Published The hidden role of the Milky Way in ancient Egyptian mythology



Astrophysicists shed light on the relationship between the Milky Way and the Egyptian sky-goddess Nut. The paper draws on ancient Egyptian texts and simulations to argue that the Milky Way might have shone a spotlight, as it were, on Nut's role as the sky. It proposes that in winter, the Milky Way highlighted Nut's outstretched arms, while in summer, it traced her backbone across the heavens.
Published Revolutionary molecular device unleashes potential for targeted drug delivery and self-healing materials



In a new breakthrough that could revolutionise medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force.
Published 'Teacher Toads' can save native animals from toxic cane toads



Scientists from Macquarie University have come up with an innovative way to stop cane toads killing native wildlife by training goannas to avoid eating the deadly amphibians.
Published Do some mysterious bones belong to gigantic ichthyosaurs?



Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.
Published Engineers design soft and flexible 'skeletons' for muscle-powered robots



Engineers designed modular, spring-like devices to maximize the work of live muscle fibers so they can be harnessed to power biohybrid robots.
Published Inexplicable flying fox found in Hydra galaxy cluster



High sensitivity radio observations have discovered a cloud of magnetized plasma in the Hydra galaxy cluster. The odd location and shape of this plasma defy all conventional explanations. Dubbed the Flying Fox based on its silhouette, this plasma will remain a mystery until additional observations can provide more insight.
Published Toothed whale echolocation organs evolved from jaw muscles



Genetic analysis finds evidence suggesting that acoustic fat bodies in the heads of toothed whales were once the muscles and bone marrow of the jaw.
Published How the moon turned itself inside out



Linking analyses of the moon's gravity field with models of its earliest evolution, scientists tell a story of the moon turning itself inside out after it solidified from a primordial magma ocean. The process left behind a vestige of dense, titanium-rich material beneath its Earth-facing side that makes its presence known by gravity anomalies.
Published Mediterranean marine worm has developed enormous eyes



Scientists are amazed at the discovery of a bristle worm with such sharp-seeing eyes that they can measure up to those of mammals and octopuses. The researchers suspect that these marine worms may have a secretive language, which uses UV light only seen by their own species. The advanced vision of such a primitive creature helps to finally settle an epic debate about the evolution of eyes.
Published Telescope detects unprecedented behavior from nearby magnetar



Captured by cutting-edge radio telescope technology, a chance reactivation of a magnetar -- the Universe's most powerful magnets -- has revealed an unexpectedly complex environment.
