Published Bird flu: Diverse range of vaccines platforms 'crucial' for enhancing human pandemic preparedness



Review of research to-date suggests vaccination remains the most effective strategy for avian influenza prevention and control in humans, despite varying vaccine efficacy across strains.
Published Intermittent fasting shows promise in improving gut health, weight management



Participants following an intermittent fasting and protein-pacing regimen, which involves evenly spaced protein intake throughout the day, saw better gut health, weight loss and metabolic responses. These benefits were notably greater than those seen with simple calorie restriction. The findings could advance our understanding of the relationship between the gut microbiome and metabolism and improve strategies for managing obesity.
Published Scientists identify gene that could lead to resilient 'pixie' corn



A widely found gene in plants has been newly identified as a key transporter of a hormone that influences the size of corn. The discovery offers plant breeders a new tool to develop desirable dwarf varieties that could enhance the crop's resilience and profitability.
Published When should you neuter or spay your dog?



A new study updates guidelines for when you should neuter or spay your dog to prevent increased risk of cancer or joint disorders.
Published Bringing back an ancient bird



Using ancient DNA extracted from the toe bone of a museum specimen, biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. The work is the first complete genetic map of the turkey-sized bird whose distant living cousins include the ostrich, emu, and kiwi.
Published Mechanisms for selective multiple sclerosis treatment strategy



Researchers have demonstrated how B cells infected with the Epstein-Barr virus (EBV) can contribute to a pathogenic, inflammatory phenotype that contributes to multiple sclerosis (MS); the group has also shown how these problematic B cells can be selectively targeted in a way that reduces the damaging autoimmune response of multiple sclerosis.
Published 'Cloaked' proteins deliver cancer-killing therapeutics into cells



Scientists have designed a way to 'cloak' proteins in a generalized technique that could lead to repurposing things like antibodies for biological research and therapeutic applications.
Published Understanding the mechanisms for local amplification of 2024 tsunamis in Iida Bay



Researchers uncover the unique mechanisms that resulted in severe tsunamis in Iida Bay caused by the 2024 Noto Peninsula Earthquake. The recent tsunamis in Iida Bay were locally amplified due to various factors, including ocean floor topology, the shape of the coastline, the location of coastal facilities, and seismic mechanisms associated with earthquakes, report scientists.
Published Scientists uncover a multibillion-year epic written into the chemistry of life



Life evolved from simple geochemical processes present on the early Earth. However, the details of this transformation remain a mystery. In this study, researchers modeled the emergence of metabolic pathways from simple geochemical precursors and concluded that surprisingly few reactions in the history of metabolism may have been lost to time.
Published Genetic mosaicism more common than thought



Researchers found that approximately one in 40 human bone marrow cells carry massive chromosomal alterations without causing any apparent disease or abnormality. Even so-called normal cells carry all sorts of genetic mutations, meaning there are more genetic differences between individual cells in our bodies than between different human beings. The discovery was enabled by a single-cell sequencing technology called Strand-seq, a unique DNA sequencing technique that can reveal subtle details of genomes in single cells that are too difficult to detect with other methods.
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 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 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 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 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 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 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.
Published Tracking down the genetic causes of lupus to personalize treatment



Treatment of autoimmune diseases like lupus has long relied on steroids to knock down the immune system, but more targeted therapies are currently undergoing clinical trials. To make sure these therapies get to the patients who will benefit, work is needed to identify the specific mutations behind each patient's disease. Researchers now report several dozen mutations associated with oversensitive toll-like receptors -- a major cause of autoimmune disease -- and linked two mutations to patients.
