KAUST researchers have developed a green synthetic biology approach using engineered algae to replicate the complex fragrances of agarwood, also known as oudh. They catalogued the chemical diversity of sesquiterpenes (STPs) in 58 agarwood samples and reproduced some of the chemical complexity of agarwood STPs in algae using synthetic biology. The team used the green alga Chlamydomonas reinhardtii to produce nine distinct STP chemical products widely found in agarwood, offering a sustainable alternative to harvesting endangered trees. Why it matters: This research provides a sustainable route for producing sought-after fragrances, reducing pressure on endangered agarwood tree populations and promoting green chemistry in the region.
KAUST researchers have developed a new synthetic biology process using metabolically engineered algae to produce fragrant sesquiterpenoids, the core compounds in agarwood and other perfumes. The process, developed by the Lauersen and Szekely groups, achieved yields 25 times higher than previous methods and allows for the synthesis of 103 types of fragrant sesquiterpenoids. It also incorporates an energy-efficient nanofiltration step and operates at room temperature with minimal waste. Why it matters: This sustainable bioprocess offers a green alternative to environmentally damaging harvesting of natural resources for the $44 billion fragrance industry, with potential applications in drug development.
A new study uses the UNet++ deep learning model and Sentinel-2 satellite data to monitor mangrove dynamics in the UAE from 2017 to 2024. The model achieved a mean Intersection over Union (mIoU) of 87.8% on the validation set. Results indicate a significant increase in mangrove area, primarily in Abu Dhabi, contributing to enhanced carbon sequestration across the UAE.
KAUST's coastal wetlands contain 90 hectares of protected mangroves that support over 240 bird species and various marine life. These mangroves, predominantly Avicennia marina, sequester CO2 at a rate 30 times higher than other forests, burying it in sediment. This "blue carbon" storage occurs because the lack of oxygen in mangrove soils prevents the degradation of organic matter. Why it matters: This highlights the critical role of Red Sea mangroves in carbon sequestration and biodiversity, emphasizing their importance for regional climate change mitigation.
A collaborative research team including KAUST scientists has located a major sink for missing ocean plastic in coastal sediments and mangrove forests of the Red Sea and Arabian Gulf. Core samples showed a pattern of plastic sedimentation aligning with the history of global plastic production since the 1950s. Mangroves efficiently lock up microplastics in coastal soil, with plastic burial rates increasing similarly to global production. Why it matters: The findings highlight the critical role of mangroves in trapping plastic pollution and provide evidence that plastic sedimentation marks the start of a new geological epoch, the Anthropocene.
Terraxy, a KAUST startup, is providing solutions to transform Saudi deserts into fertile landscapes using CarboSoil, an advanced biochar product. CarboSoil improves soil fertility, conserves water, and enhances plant growth, and is tailored to counteract the alkaline nature of Saudi sandy soils. Terraxy is working with Saudi Aramco and NEOM to implement its technologies, servicing over 60,000 native plants. Why it matters: This innovation directly supports the Saudi Green Initiative and offers a sustainable approach to combat desertification and promote food production in the region.
Insyab, a startup specializing in collaborative robotics and drone solutions, was founded by KAUST alumnus Dr. Ahmed Bader and KAUST Professor Mohamed-Slim Alouini. Their flagship product, AirFabric™, is a broadband ultra-low-latency wireless connectivity solution enabling teams of unmanned vehicles to collaborate effectively. The technology allows robots to interact in real time and share learning, unlocking a "1+1=3" value proposition. Why it matters: This highlights KAUST's role in fostering deep-tech entrepreneurship and developing innovative solutions for industrial automation in the region.
KAUST and the Saudi Food and Drug Authority (SFDA) have partnered to develop a new method using nuclear magnetic resonance (NMR) to detect adulterants in olive oil. The method aims to identify and quantify vegetable oils mixed with olive oil, addressing concerns about the mislabeling of olive oil in the Saudi market. KAUST's comprehensive suite of NMR machines was critical for the project. Why it matters: This collaboration enhances food safety and quality control in Saudi Arabia, a major olive oil importer, and helps to ensure consumers receive authentic, high-quality products.
