Published Researchers have unveiled a new method to manipulate cell movement in embryos



Scientists have developed a new method that can manipulate the movement of embryonic cells using short-time attractors.
Published How killifish embryos use suspended animation to survive over 8 months of drought



The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish's embryos enter a state of extreme suspended animation or 'diapause' for approximately 8 months. Now, researchers have uncovered the mechanisms that enabled the killifish to evolve this extreme survival state.
Published Close to 1 in 2 surveyed say they would use air taxis in the future



Through a study of 1,002 participants, scientists have found that almost half (45.7 per cent) say they intend to use air taxis when they become available, with over one-third (36.2 per cent) planning to do so regularly. According to the findings, the intention to take autonomous air taxis is associated with factors such as trust in the AI technology deployed in air taxis, hedonic motivation (the fun or pleasure derived from using technology), performance expectancy (the degree to which users expect that using the system will benefit them), and news media attention (the amount of attention paid to news about air taxis).
Published Transgenic expression of rubisco factors increases photosynthesis and chilling tolerance in maize



Maize is one of the world's most widely grown crops and is essential to global food security. But like other plants, its growth and productivity can be limited by the slow activity of Rubisco, the enzyme responsible for carbon assimilation during photosynthesis. Scientists have now demonstrated a promising approach to enhancing Rubisco production, thus improving photosynthesis and overall plant growth.
Published Florida fossil porcupine solves a prickly dilemma 10-million years in the making



An exceptionally rare fossilized porcupine skeleton discovered in Florida has allowed researchers to trace the evolutionary history for one of North America's rarest mammals.
Published Secrets of sargassum: Scientists advance knowledge of seaweed causing chaos in the Caribbean and West Africa



A research team tracked and studied floating sargassum in order to unlock its potential to be used to produce sustainable products.
Published Echidnapus identified from an 'Age of Monotremes'



Australian researchers have found evidence of the oldest known platypus and a new species, dubbed 'echidnapus', which has a platypus-like anatomy alongside features that more closely resemble an echidna.
Published AI headphones let wearer listen to a single person in a crowd, by looking at them just once



Engineers have developed an artificial intelligence system that lets someone wearing headphones look at a person speaking for three to five seconds to 'enroll' them. The system then plays just the enrolled speaker's voice in real time, even as the pair move around in noisy environments.
Published Entomologist sheds light on 250-year-old mystery of the German cockroach



Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an outdoor-living species in Asia.
Published Observing mammalian cells with superfast soft X-rays



Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.
Published Caterpillars can detect their predators by the static electricity they emit



Caterpillars respond defensively to electric fields similar to those emitted by their natural predators, scientists have found.
Published Imperceptible sensors made from 'electronic spider silk' can be printed directly on human skin



Researchers have developed a method to make adaptive and eco-friendly sensors that can be directly and imperceptibly printed onto a wide range of biological surfaces, whether that's a finger or a flower petal.
Published Key role of plant-bacteria communication for the assembly of a healthy plant microbiome supporting sustainable plant nutrition



In an interdisciplinary study, researchers discovered that symbiotic bacteria communicate with legume plants through specific molecules and that this communication influences which bacteria grow near the plant roots. The findings provide insights into how plants and soil bacteria form beneficial partnerships for nutrient uptake and resilience. These results are a step towards understanding how communication between plants and soil bacteria can lead to specific beneficial associations providing plants with nutrients.
Published New approach to Epstein-Barr virus and resulting diseases



The Epstein-Barr virus can cause a spectrum of diseases, including a range of cancers. Emerging data now show that inhibition of a specific metabolic pathway in infected cells can diminish latent infection and therefore the risk of downstream disease.
Published Birth of universe's earliest galaxies observed for first time



Researchers have now seen the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important knowledge about the universe.
Published Psychedelic drug-induced hyperconnectivity in the brain helps clarify altered subjective experiences



A new study shows that the use of psilocybin, a compound found in the widely known 'magic mushrooms,' initiates a pattern of hyperconnectivity in the brain linked to the ego-modifying effects and feelings of oceanic boundlessness. The findings help explain the so-called mystical experiences people report during the use of psychedelics and are pertinent to the psychotherapeutic applications of psychedelic drugs to treat psychiatric disorders such as depression.
Published New 'atlas' provides unprecedented insights on how genes function in early embryo development



Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers captured unprecedented insights on how embryonic development unfolds.
Published Planet hunters unveil massive catalog of strange worlds



While thousands of planets have been discovered around other stars, relatively little is known about them. A NASA catalog featuring 126 exotic, newly discovered worlds includes detailed measurements that allow for comparisons with our own solar system.
Published Novel approach to interrogate tissue-specific protein-protein interactions



Multicellular organisms, like animals and plants, have complex cells with diverse functions. This complexity arises from the need for cells to produce distinct proteins that interact with each other. This interaction is crucial for cells to carry out their specific tasks and to form complex molecular machinery. However, our current understanding of such protein-protein interactions often lacks cellular contexts because they were usually studied in an in vitro system or in cells isolated from their tissue environment. Effective methods to investigate protein-protein interactions in a tissue-specific manner are largely missing.
Published Biodiversity in crabs: More than counting species



Researchers compare the shield shapes of crabs and find unexpected differentiation.
