A KAUST-led research team has observed intergenerational epigenetic inheritance in corals, demonstrating that corals pass patterns of DNA to their offspring. The research, published in Nature Climate Change, shows that corals can adapt to environmental changes and pass those traits on through DNA methylation patterns. This is the first time this process has been observed in animals, previously only seen in plants. Why it matters: This finding could enable biologists to train corals in nurseries to produce offspring better equipped to survive changing marine environments, aiding coral reef restoration efforts.
The paper introduces a benchmark of 1,000 multiple-choice questions to evaluate LLMs on Islamic inheritance law ('ilm al-mawarith). Seven LLMs were tested, with o3 and Gemini 2.5 achieving over 90% accuracy, while ALLaM, Fanar, LLaMA, and Mistral scored below 50%. Error analysis revealed limitations in handling structured legal reasoning. Why it matters: This research highlights the challenges and opportunities for adapting LLMs to complex, culturally-specific legal domains like Islamic jurisprudence.
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.
Carlo Maj from the University of Marburg will discuss using polygenic modeling to analyze the genetic architecture of multifactorial traits. He will present how these approaches can be used to predict the genetically driven components of complex phenotypes. The talk highlights the potential of these methods to bridge genomic research and genetic epidemiology using biobank data. Why it matters: Such methods could improve disease risk assessment and advance personalized risk management in the region if applied to local biobanks or datasets.
KAUST's Environmental Epigenetics Program (KEEP), led by Prof. Valerio Orlando, focuses on understanding how cells acquire and maintain memory, particularly in response to environmental factors. The research investigates the role of non-coding RNA and chromosomal components in regulating gene expression beyond the DNA sequence. Epigenetics explains how the same genome can be interpreted differently, allowing cells and organs to adapt to changing conditions. Why it matters: This research could provide insights into how environmental factors impact gene expression and cell function, potentially leading to advances in understanding and treating diseases.
KAUST Discovery Professor Aranda's team has been researching coral adaptation to temperature and ocean acidification. The research is focused on the transgenerational aspect of this adaptation using controlled environments. The research has been ongoing for the past two years. Why it matters: Understanding the epigenetic mechanisms of climate resilience in corals is crucial for conservation efforts in the Red Sea and beyond.
This article discusses domain shift in machine learning, where testing data differs from training data, and methods to mitigate it via domain adaptation and generalization. Domain adaptation uses labeled source data and unlabeled target data. Domain generalization uses labeled data from single or multiple source domains to generalize to unseen target domains. Why it matters: Research in mitigating domain shift enhances the robustness and applicability of AI models in diverse real-world scenarios.
