Published Separating out signals recorded at the seafloor



Research shows that variations in pyrite sulfur isotopes may not represent the global processes that have made them such popular targets of analysis and interpretation. A new microanalysis approach helps to separate out signals that reveal the relative influence of microbes and that of local climate.
Published How shipwrecks are providing a refuge for marine life



New research has highlighted how the estimated 50,000 wrecks around the UK coastline are protecting the seabed, and the species inhabiting it, in areas still open to bottom-towed fishing.
Published New clues into the head-scratching mystery of itch



Scientists show for the first time that bacteria can cause itch by activating nerve cells in the skin. The findings can inform new therapies to treat itch that occurs in inflammatory skin conditions like eczema and dermatitis.
Published Predicting the fate of shallow coastal ecosystems for the year 2100



A new study of shallow-water ecosystems estimates that, by 2100, climate change and coastal land usage could result in significant shrinkage of coral habitats, tidal marshes, and mangroves, while macroalgal beds remain stable and seagrass meadows potentially expand.
Published Nutrient found in beef and dairy improves immune response to cancer



Trans-vaccenic acid (TVA), a long-chain fatty acid found in meat and dairy products from grazing animals such as cows and sheep, improves the ability of CD8+ T cells to infiltrate tumors and kill cancer cells, according to a new study.
Published Team discovers rules for breaking into Pseudomonas



Researchers report that they have found a way to get antibacterial drugs through the nearly impenetrable outer membrane of Pseudomonas aeruginosa, a bacterium that -- once it infects a person -- is notoriously difficult to treat.
Published Laser-powered 'tweezers' reveal universal mechanism viruses use to package up DNA



Researchers have used laser-powered ‘optical tweezers’ to reveal a universal motor mechanism used by viruses for packaging their DNA into infectious particles.
Published Deep-sea mining and warming trigger stress in a midwater jellies



The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.
Published Unearthing how a carnivorous fungus traps and digests worms



A new analysis sheds light on the molecular processes involved when a carnivorous species of fungus known as Arthrobotrys oligospora senses, traps and consumes a worm.
Published Coffee grounds may hold key to preventing neurodegenerative diseases



A team of researchers found that caffeic-acid based Carbon Quantum Dots (CACQDs), which can be derived from spent coffee grounds, have the potential to protect brain cells from the damage caused by several neurodegenerative diseases.
Published Protect delicate polar ecosystems by mapping biodiversity



Concerted action is required to mitigate the impact of warming on polar ecosystems and sustainably manage these unique habitats.
Published Innovative aquaculture system turns waste wood into nutritious seafood



Innovative aquaculture system turns waste wood into nutritious seafood. Researchers hoping to rebrand a marine pest as a nutritious food have developed the world's first system of farming shipworms, which they have renamed 'Naked Clams'.
Published Half of tested caviar products from Europe are illegal, and some aren't even caviar



Wild caviar, a pricey delicacy made from sturgeon eggs, has been illegal for decades since poaching brought the fish to the brink of extinction. Today, legal, internationally tradeable caviar can only come from farmed sturgeon, and there are strict regulations in place to help protect the species. However, by conducting genetic and isotope analyses on caviar samples from Bulgaria, Romania, Serbia, and Ukraine -- nations bordering the remaining wild sturgeon populations -- a team of sturgeon experts found evidence that these regulations are actively being broken. Their results show that half of the commercial caviar products they sampled are illegal, and some don't even contain any trace of sturgeon.
Published A deep-sea fish inspired researchers to develop supramolecular light-driven machinery



Chemists have developed a bioinspired supramolecular approach to convert photo-switchable molecules from their stable state into metastable one with low-energy red light. Their work enables fast, highly selective, and efficient switching, providing new tools for energy storage, activation of drugs with light, and sensing applications.
Published Heart repair via neuroimmune crosstalk



Unlike humans, zebrafish can completely regenerate their hearts after injury. They owe this ability to the interaction between their nervous and immune systems, as researchers now report.
Published New method to help with analysis of single cell data



CITE-seq (cellular indexing of transcriptomes and epitopes) is an RNA sequencing-based method that simultaneously quantifies cell surface protein and transcriptomic data within a single cell readout. The ability to study cells concurrently offers unprecedented insights into new cell types, disease states or other conditions. While CITE-seq solves the problem of detecting a limited number of proteins while using single-cell sequencing in an unbiased way, one of its limitations is the high levels of background noise that can hinder analysis.
Published Heat tolerant coral may trade fast growth for resilience



Algae living within the soft tissue of coral supply much of the energy needed by their hosts, and some symbiotic algae help coral withstand warmer water better than others. Researchers have now found that there was a tradeoff for corals dominated by the thermally sensitive algae -- they have higher growth, but only in cooler water.
Published Rediscovery of rare marine amoeba Rhabdamoeba marina



Researchers have rediscovered and successfully cultivating Rhabdamoeba marina -- a rare marine amoeba that has only been reported in two cases in the past century. Using this culture strain, they performed a comprehensive analysis of its genetic sequence, revealing for the first time the phylogenetic position of this enigmatic amoeba, and proposed a novel taxonomic classification based on their research findings.
Published Genomic tug of war could boost cancer therapy



Researchers have discovered a 'genomic tug of war' in animal studies that could influence how well certain patients -- or certain cancers -- respond to decitabine, a drug used to treat myelodysplastic syndromes that is plagued by drug resistance issues. For the first time, researchers show that decitabine causes coding and non-coding regions of DNA to engage in a tug of war for a gene activator, called H2A.Z. Typically, deticabine draws this gene activator away from coding DNA, causing gene expression to grind to a halt and cells to die. However, many types of cancer have very high levels of H2A.Z, which may help them overcome this decitabine-induced tug of war, allowing the cancer to grow.
Published How cell identity is preserved when cells divide



A new theoretical model helps explain how epigenetic memories, encoded in chemical modifications of chromatin, are passed from generation to generation. Within each cell's nucleus, researchers suggest, the 3D folding patterns of its genome determines which parts of the genome will be marked by these chemical modifications.
