Saudi Research Institutes Achieve Record-Breaking Performance in Data Security
A joint team of researchers led by scientists at Saudi Arabia's King Abdullah University of Science and Technology (KAUST) and King Abdulaziz City for Science and Technology (KACST) reported the fastest quantum random number generator (QRNG) to date based on international benchmarks.
The QRNG, which passed the required randomness tests of the National Institute of Standards and Technology, could produce random numbers at a rate nearly a thousand times faster than other QRNG, said KAUST in a statement on Tuesday.
'This is a significant leap for any industry that depends on strong data security,' said KAUST Professor Boon Ooi, who led the study, published in Optics Express.
According to the statement, random number generators are critical for industries that depend on security, such as health, finance, and defense. But the random number generators currently used are vulnerable because of an intrinsic flaw in their design.
'Most random number generators are 'pseudo random number generators.' In other words, they seem random, but in reality, they are complicated algorithms that can be solved. QRNGs do not suffer from this concern,' explained Ooi.
The reason is that QRNG use the principles of quantum mechanics to produce a truly unpredictable random number. The high random number generation rate reported in the new study was the result of innovations made by the scientists in the fabrication and the post-processing algorithms of the device.
The QRNG was constructed using micro-LEDs (light emitting diodes) less than a few micrometers in size, which reduces their energy demands and suggests the QRNG are portable, expanding the types of applications.
'KACST, in its capacity as the national laboratory, is committed to advancing applied research that directly supports the objectives of Saudi Arabia's Vision 2030, particularly in establishing global leadership across strategic sectors, including quantum-enabled innovations,' said study contributor, Microelectronics and Semiconductors Institute researcher, and KACST Center of Excellence for Solid-State Lighting director Dr. Abdullah Almogbel.
'Undertaking such research initiatives is expected to generate substantial value for a wide range of industries and further solidify their global standing,' he added.
The National Institute of Standards and Technology is recognized internationally for providing benchmarks to ascertain the quality of randomness.

What Saudi Arabia's ancient lava fields reveal about its volcanic past — and tourism potential
JEDDAH: Scattered across Saudi Arabia's vast deserts and mountains lie more than 2,500 volcanic craters — relics of a fiery geological past that continues to intrigue scientists and thrill adventurous travellers today. These ancient volcanoes have not erupted in centuries. Their silence, however, belies their significance. 'The Kingdom possesses one of the largest volcanic fields (locally known as Al-Harrat) in the world,' Turki Essam Al-Sehli, senior director of the Geohazard Center at the Saudi Geological Survey, told Arab News. 'These fields cover an area of approximately 90,000 square kilometers — around 4.6 percent of the Kingdom's total area.' The last known eruption was in 1256 AD, when lava from Al-Harrat Rahat flowed within 20 kilometers of Madinah. While dramatic in its time, such activity has long since ceased. 'The Kingdom has experienced relative volcanic stability for centuries,' Al-Sehli said. This dormancy, combined with the dramatic scenery of ancient lava fields, has opened the door to a growing trend: volcano tourism. From stark black cones to craters that plunge deep into the Earth, Saudi Arabia's volcanic landscape offers some of the most breathtaking geological sights in the region. Among the most striking is Al-Wahbah, a vast crater near Taif that is 250 meters deep and more than two kilometers across. In the Asir region, Jabal Farwa — the Kingdom's tallest volcanic peak — rises more than 3,000 m above sea level. Meanwhile, the Khaybar tract is home to Mount Al-Qadar, where lava once flowed for more than 50 km, and the otherworldly Mount Al-Abyad, known for its pale color and unusual formations. 'Fields like Rahat and Khaybar are characterized by hundreds of volcanic cones formed by mild explosive eruptions and vast lava flow areas reaching lava flow length over 50 km on some occasions, which grant them significant geological and scientific importance,' Al-Sehli said. 'Additionally, they are considered the largest in the Arab world and the Middle East.' • The last volcanic eruption in the Hijaz region occurred in 1256 AD, southeast of Madinah. • Its lava flow extended for 23 kilometers, stopping 8.2 km short of the Prophet's Mosque. • Saudi Arabia's volcanic landscape has the potential to become a global tourist destination. While some fields are still classified as 'potentially active,' experts agree there is no cause for alarm. 'Some volcanic fields are categorized as potentially active due to the geophysical indicators of eruptible magma in the mid-crust, which means there is a possibility — even if slight — of future volcanic activity,' Al-Sehli said. 'Currently, there are no signs of imminent danger.' Indeed, any future eruption, while highly unlikely in the short term, would be closely monitored. The Saudi Geological Survey operates a state-of-the-art seismic and volcanic surveillance network designed to detect even the slightest changes beneath the surface. Should a large eruption take place, however, the environmental impact and the effect on the local climate could be significant. 'In the event of a major volcanic eruption, the emission of fine volcanic ash and gases such as sulfur dioxide, carbon dioxide and other greenhouse gases into the upper layers of the atmosphere could lead to temporary cooling of the local or regional climate, as well as generating acid rainfall,' Al-Sehli said. With little risk posed by these sleeping giants and great natural beauty to explore and enjoy, Saudi Arabia is increasingly investing in geotourism — promoting its volcanic fields not as hazards, but as heritage. 'There is growing interest in developing geological tourism in the Kingdom,' Al-Sehli said. 'The ministry of tourism is collaborating with the Saudi Geological Survey to develop and preserve these geological sites.' The Saudi Geological Survey's role extends far beyond monitoring. It produces maps and reports, conducts scientific research, and works to raise public awareness through exhibitions and outreach programs. It also helps identify and conserve key geological sites, ensuring that Saudi Arabia's volcanic past is protected for future generations. From lava trails to towering cones, the Kingdom's volcanic fields offer a window into Earth's ancient forces — and a unique travel experience for those looking to explore a different side of Saudi Arabia. These volcanoes may be dormant, but their potential — for knowledge, for tourism, and for wonder — is anything but.

Climate innovation can enhance nature-based solutions
Success will depend not only on the number of trees but on how effectively they are planted, maintained, and measured. (SGI photo) As Saudi Arabia commits to planting 10 billion trees and rehabilitating 40 million hectares in the coming decades under the Saudi Green Initiative, success will depend not only on the number of trees but on how effectively they are planted, maintained, and measured. Precision, ecosystem sustainability, and transparent monitoring are essential. Emerging climate technologies using artificial intelligence —such as satellite-based remote sensing and advanced carbon quantification platforms — offer transformative tools to enhance the effectiveness of nature-based solutions. This will enable the Kingdom to deliver measurable results while advancing global climate adaptation aspirations. Nature-based solutions, including afforestation, mangrove rehabilitation, and wetland restoration, can provide up to 37 percent of the cost-effective carbon mitigation required by 2030 to meet the Paris Agreement goals. However, implementing nature-based solutions in Saudi Arabia's hyper-arid environment presents unique challenges. Climate stressors such as extreme heat, saline soils, and water scarcity require data-driven approaches to ensure ecological suitability, long-term survival, and resilience. Technologies such as light detection and ranging, or LIDAR, which use laser pulses to map terrain and vegetation in three dimensions, allow detailed analysis of canopy structure, soil degradation, and vegetation health. When integrated with AI and hyperspectral imaging, these tools can identify optimal restoration sites, track survival rates, and verify carbon uptake in near real time. Institutions such as the National Center for Vegetation Cover could use this technology to improve resource targeting and support digital monitoring, reporting, and verification systems for national and international carbon markets. Globally, countries are successfully leveraging such technologies. Kenya's Regreening Africa initiative employs drone imagery and AI to evaluate large-scale restoration efforts, using geospatial tools to monitor tens of thousands of hectares and significantly improve outcomes. In Peru, satellite-based forest monitoring platforms enhance transparency and help prevent illegal deforestation in Amazonian restoration zones. These examples offer replicable models that Saudi Arabia can adapt and scale. The economic rationale is equally compelling. The social cost of carbon, reflecting the economic damage from each additional tonne of CO2 emitted, can reach as high as $185 per tonne depending on the applied discount rate and modeling assumptions, according to estimates reported in 2022 by Kevin Rennert and fellow researchers in the journal Nature. In contrast, the cost of restoring mangroves to sequester carbon has been estimated to range from $4.50 to $18 per tonne of CO2, depending on site-specific factors and carbon recovery assumptions, while delivering additional benefits such as coastal protection, biodiversity enhancement, and improved fisheries. In a country where approximately one third of the population resides along the coast, restoring mangroves and wetlands becomes a dual-purpose strategy that combines mitigation with adaptation. Technology also reduces the risk of maladaptation, where restoration efforts fail due to poor species selection or lack of climate-fit design. Applying frameworks like dynamic adaptive policy pathways can help Saudi policymakers sequence restoration phases under uncertainty and adjust plans based on feedback and risk thresholds. Even the most advanced tools will fall short without the trust, knowledge, and participation of those most affected by environmental change. Adnan Masoudy & Hassan Alzain Co-developing projects with local communities and scientists ensures financial stability and long-term social resilience. Adaptation finance remains critically underfunded. The Adaptation Gap Report 2024 estimates that the financing needed is between $231 and $416 billion per year, up from previous estimates of $194 to $366 billion, reflecting rising global costs and urgent adaptation needs. To fully realize this potential, Saudi Arabia should prioritize advancing three strategic steps. First, launch a national open-access geospatial dashboard that integrates LIDAR, AI, and remote sensing data to track nature-based solutions progress nationwide. Second, engage more deeply with global platforms such as the UN Decade on Ecosystem Restoration, the Global Mangrove Alliance, and the Forest Carbon Partnership Facility to exchange technical knowledge and obtain access to climate finance. Third, establish a climate and nature tech innovation hub in collaboration with local universities to pilot and localize nature-based solutions, monitoring solutions tailored for drylands, while accelerating the development and deployment of new climate and nature-based startups in the region. As Princess Reema bint Bandar Al-Saud, the Kingdom's ambassador to the US, eloquently stated on SGI Day 2025: 'The future is not something that comes at us; it's something we create ... Climate action is not a dream — it is a reality we are building together.' Her words capture the spirit of SGI as not just a national strategy, but a movement defined by momentum, measurable action, and collective resolve. That momentum is already visible. As of 2024, Saudi Arabia has planted over 115 million trees and restored 118,000 hectares of degraded land — a significant leap from where the journey began just a few years ago. These achievements demonstrate that bold climate pledges are being converted into tangible, large-scale outcomes on the ground. But technology and investment alone are not enough. As explained by Robert Klee, senior lecturer and managing director of clean energy programs at the Yale Center for Business and the Environment: 'Nature-based solutions can be empowered by technology, but must be governed by people — especially those most vulnerable to climate risks. 'It is in aligning science, justice, and local knowledge that real climate progress takes root.' This insight points to a deeper truth: meaningful climate progress depends as much on governance and inclusion as it does on innovation. Even the most advanced tools will fall short without the trust, knowledge, and participation of those most affected by environmental change. Within the SGI framework, embedding local leadership and equity into restoration design can elevate both the impact and legitimacy of nature-based solutions across Saudi Arabia's diverse landscapes. By fusing nature and innovation, and engaging local communities in the development and deployment of nature-based solutions, Saudi Arabia can transform its drylands into living laboratories of climate resilience. The SGI offers more than a greening strategy. With smart climate technologies, it can become a global model for how climate ambition, ecological science, cutting-edge tools, and social support converge to drive meaningful environmental transformation in the decades to come. • Adnan Masoudy is manager of corporate sustainability, environment, and biodiversity at Ma'aden and Hassan Alzain is author of the award-winning book 'Green Gambit.'
