KAUST researchers are using 3D printing with a novel calcium carbonate ink to create coral support structures that accelerate coral restoration. Their approach, named 3D CoraPrint, involves printing coral microfragments onto the structure, offering a head start for reef recovery. Two methods were developed: printing a mold for reproduction and direct printing for customization. Why it matters: This eco-friendly technique provides a potentially scalable solution to combat coral reef degradation, leveraging advanced materials and fabrication for ecological conservation in the region and beyond.
KAUST researchers have conducted the first measurements of deep-sea corals in the Red Sea. They retrieved specimens of three different species at depths of 300-750 meters and temperatures exceeding 20 degrees Celsius. This discovery challenges the existing understanding that deep-sea corals are exclusive to cold-water environments. Why it matters: The research expands known ecosystem boundaries for deep-sea corals and demonstrates their resilience in warm, nutrient-poor waters, offering new insights into marine biodiversity and adaptation.
KAUST scientists have successfully expanded coral spawning through controlled systems, producing approximately two million eggs from six coral species this season to support reef research. Researchers at KAUST's Coastal and Marine Resources (CMR) Core Lab developed facilities that replicate environmental signals to trigger spawning beyond natural seasonal cycles, enabling year-round access to gametes and larvae. This program represents the first successful implementation of shifted phase coral spawning in Saudi Arabia. Why it matters: This breakthrough provides unprecedented opportunities for advancing Red Sea reef restoration and marine science, allowing for continuous study of coral early-life resilience.
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.
KAUST researchers have found that the symbiotic relationship between corals and micro-algae is 100 million years older than previously thought, dating back 160 million years. The study suggests that corals have endured numerous climate change events due to their biological characteristics. Researchers developed an updated naming scheme using genetic techniques to identify different micro-algal symbionts. Why it matters: This discovery offers a glimmer of hope for coral survival in the face of modern global warming and enhances conservation efforts, while also modernizing coral symbiont taxonomy.
