A KAUST team developed piRNAi, a gene-silencing tool in nematode worms using synthetic RNA sequences interacting with the piRNA pathway. They successfully silenced genes involved in sex determination and other functions, demonstrating multiplexed gene silencing. The gene silencing lasted for varying durations across generations, up to six generations. Why it matters: This expands the molecular toolkit for gene manipulation and offers potential therapeutic applications in humans, given the presence of the same gene-silencing pathway.
KAUST researchers are studying the chemical signals in pearl millet that trigger the germination of Striga seeds, a parasitic plant. The research aims to understand the biological compounds involved in Striga infestation. The goal is to induce Striga germination without host plants, reducing Striga seed banks in infested soils. Why it matters: Addressing Striga infestation can improve crop yields and food security, especially in regions relying on pearl millet.
KAUST researchers have discovered how sea anemones recycle nitrogen waste, allowing them to thrive in nutrient-poor ocean environments. The study used laser microdissection and single-cell RNA-sequencing to analyze tissue-specific gene expression in Aiptasia. They found that anemones distribute glucose received from symbionts across tissues to recycle nitrogen waste. Why it matters: This research enhances understanding of coral reef ecosystems and their resilience, which is particularly relevant for Red Sea biodiversity and Saudi Arabia's environmental efforts.
KAUST researchers are collaborating with the Saudi Ministry of Environment, Water & Agriculture (MEWA) to develop sensor technology for early detection of red palm weevils. The weevil larvae cause significant damage to palm trees by hollowing them out from the inside. Early detection is crucial because visible signs of distress indicate advanced infection and low chances of rescue. Why it matters: This research aims to protect date farming and crops, which are a vital economic resource for Saudi Arabia and the broader region.
Artists from Switzerland collaborated with researchers at KAUST's Red Sea Research Center to photograph autonomous reef monitoring structures (ARMS). ARMS are artificial towers that capture small critters colonizing coral reefs, developed to measure marine biodiversity. KAUST has deployed and retrieved over 180 ARMS units since 2013 to study cryptobenthic biodiversity, which represents up to 70% of a reef's biodiversity. Why it matters: This collaboration highlights the innovative approaches being used to study marine ecosystems in the Red Sea and underscores the importance of interdisciplinary collaborations in advancing scientific understanding.
KAUST Discovery Professor Jesper Tegnér collaborated with UK researchers to develop algorithms explaining decision-making in insects and rats. Assoc. Prof. Robert Hoehndorf's lab introduced a tool for identifying genetic variants linked to rare diseases based on patient symptoms. KAUST scientists also studied monkeypox infection of human skin using stem cells and marine microbiome adaptation to thermal changes. Why it matters: These diverse research projects highlight KAUST's contributions to computational biology, virology, and marine science, advancing knowledge with implications for healthcare and environmental challenges.
KAUST researchers, in collaboration with Nanyang Technological University, have discovered a unique chiral structure in gold nanowires. The nanowires exhibit a Boerdijk-Coxeter-Bernal (BCB) helix structure, achieved through a seed-mediated substrate growth method, reaching a minimum diameter of 3 nanometers. High-resolution transmission electron microscopy (HRTEM) at KAUST was crucial in revealing the structure. Why it matters: This breakthrough in chiral metallic nanowire production could lead to advancements in chemical separation, sensing, and catalysis due to the unique properties of chiral crystals.
