Saudi science university makes world's top 100
DHAHRAN: King Fahd University of Petroleum and Minerals has achieved a milestone by entering the list of the world's top 100 establishments, ranking 67th in the 2025 QS World University Rankings after being 101st last year. The transformation has taken place across academic, research, and administrative domains. Nearly 100 new programs have been launched, including innovative undergraduate and graduate offerings. The university has also introduced the region's first entrepreneurship program, granting students and researchers full ownership of their startups in a move that reflects a modern, innovation-driven academic culture focused on economic empowerment. In addition, the university has adopted the FAST transformation model and the AI+X initiative, which integrates artificial intelligence as an integral knowledge component across all disciplines, making it a core academic requirement for all students. The university has also achieved the highest female enrollment rate in engineering programs globally, and attracted students from more than 75 countries, according to the Saudi Press Agency.

Scientists spot a mysterious 'ghost plume' in Oman – and it suggests Earth's core could be LEAKING
A mysterious 'ghost plume' has been spotted beneath eastern Oman. Emanating from the Earth's core, this hot pillar of soft rock is pushing upwards from 410 miles (660km) beneath the planet's surface. Until now, the ghost plume was hidden because it hadn't broken through the surface to form volcanoes. But, in a new study, researchers have proved the 'ghost plume' exists by looking at how it slows down passing earthquake waves. Since waves move slower through hot, soft rock, this is a key sign that there is a plume hidden beneath the surface. Having shown that one ghost pillar exists, the researchers say there might be many more waiting to be found around the world. Worryingly , that might mean the Earth's core is leaking heat faster than scientists previously thought. Lead author Dr Simone Pilia, of the King Fahd University of Petroleum, Engineering and Geosciences, told MailOnline: 'It's a reminder that surface silence doesn't mean the mantle is quiet.' Ghost plumes are a type of mantle plume, pillars of hot rock which form when heat wells up from the boundary of the Earth's outer core, some 1,800 miles (2,890 km) beneath the surface. These are usually easy to find because they produce lots of volcanic activity at the surface as the molten rock is forced upwards. Dr Pilia says: 'A ghost plume is a mantle plume that doesn't produce observable surface volcanism, making it essentially "invisible" to traditional geological observation.' Although there are no volcanoes in Oman, Dr Pilia noticed that seismic waves from earthquakes slow down as they travel through this area. By analysing the way these waves were warped, Dr Pilia, who named the feature 'Dani' after his son, realised that there might be a cylinder of hot rock hidden beneath the ground. Dr Pilia and his co-authors used geological evidence and computer simulation to show how the presence of a mantle plume fits with what geologists already know about the area. Together, this evidence created a strong case that there is an elusive ghost plume lurking underground. Dr Pilia says: 'Despite lacking surface volcanic activity, all the deep-Earth signals of the plume are there.' Normally, mantle plumes would emerge at the surface as volcanoes. But Oman is above a layer of thick rock which keeps the plume well below the surface which it can't melt through Five layers of Earth Crust: To a depth of up to 43 miles (70km), this is the outermost layer of the Earth, covering both ocean and land areas. Mantle: Going down to 1,795 miles (2,890km) with the lower mantle, this is the planet's thickest layer and made of silicate rocks richer in iron and magnesium than the crust overhead. Outer core: Running to a depth of 3,200 miles (5,150km), this region is made of liquid iron and nickel with trace lighter elements. Inner core: Going down to a depth of 3,958 miles (6,370km) at the very centre of Earth, this region is thought to be made of solid iron and nickel. Innermost core: Within the inner core, this region is solid iron in a different, but unknown structure to the inner core. Based on this evidence, the plume is likely to be a cylinder around 125 to 185 miles in diameter (200-300km) and extends at least 410 miles (660km) deep. The rocks within the plume are up to 300°C (540°F) hotter than the surrounding mantle. Although these rocks are extremely hot, the researchers say the plume isn't producing volcanic activity due to a 'lid' of rock near the surface. Unlike above many other plumes, this 60-mile-thick (100km) layer of rock prevents the plume from melting its way to the surface. Dr Pilia says: 'Even if the plume is hot - and our data suggest it is - the pressure at those depths makes it very hard for melt to form and reach the surface. So, the plume exists, but it's essentially trapped.' Luckily for the people of Oman, Dr Pilia says this means the plume is 'very unlikely' to produce any volcanic activity in the foreseeable future. According to the modelling, the plume has been there for at least 40 million years, during which time it affected the drift of the Indian continental plate. The plume may also explain why parts of Oman continue to rise even after tectonic compression, a process which squeezes the Earth's crust together, has stopped. The researchers' modelling (pictured) suggests that the plume is a cylinder around 125 to 185 miles in diameter (200-300km) extending at least 410 miles (660km) beneath the surface Most importantly, this discovery also suggests that there may be many other ghost plumes out there waiting to be discovered, especially under areas with thick rock caps. That would mean more heat is leaking from the Earth's core than researchers previously thought, which could have big implications for the study of Earth's inner layers. Mantle plumes are a key part of how the Earth distributes heat and pressure deep beneath the surface. Studies have shown that they are closely linked to plate tectonics, the planet's magnetic field, and even the evolution of life on Earth. Dr Pilia says there are 'likely' many more ghost plumes around the world but these may be small and hard to spot without special networks of seismic detectors. 'What makes the Dani plume stand out is that we had just the right data, in just the right place, to finally see it. 'It's a reminder that surface silence doesn't mean the mantle is quiet.' The Earth is moving under our feet: Tectonic plates move through the mantle and produce Earthquakes as they scrape against each other Tectonic plates are composed of Earth's crust and the uppermost portion of the mantle. Below is the asthenosphere: the warm, viscous conveyor belt of rock on which tectonic plates ride. Earthquakes typically occur at the boundaries of tectonic plates, where one plate dips below another, thrusts another upward, or where plate edges scrape alongside each other. Earthquakes rarely occur in the middle of plates, but they can happen when ancient faults or rifts far below the surface reactivate.

Olympiad delegates explore Saudi heritage, hospitality
Dhahran: International delegations taking part in the Asian Physics Olympiad, hosted by Saudi Arabia in Dhahran from May 4 to 12, enjoyed a dynamic schedule of scientific competitions, cultural activities, educational events and entertainment. The enriching experience brought together 240 students from 30 countries and 110 international physics specialists, the Saudi Press Agency reported. Beyond the competitions, the program included educational and cultural visits highlighting Saudi Arabia's rich heritage and scientific progress, while promoting global youth engagement and cultural exchange. Wearing traditional Saudi attire as a sign of respect, participants experienced the Kingdom's hospitality, sampled Saudi cuisine and took part in interactive events that fostered cultural connection. This year's Olympiad holds special significance as it marks the 25th anniversary of the competition. For more than two decades, it has united talented youth from across the globe, encouraging scientific excellence and cross-cultural understanding. The final results — organized by the Ministry of Education, the King Abdulaziz and His Companions Foundation for Giftedness and Creativity, and King Fahd University of Petroleum and Minerals — will be announced during the closing ceremony on May 11 at King Fahd University in Dhahran.
