Saudi Arabia’s King Abdullah University of Science and Technology (KAUST) ranked first in the Times Higher Education (THE) Arab University Rankings 2023, a move up from KAUST's ranking as second in the previous year.

"KAUST also scored a perfect 100 for research environment, one of only two universities to do so, in the society pillar (measuring industry income, as well as participation and performance in the impact rankings) and the international outlook pillar (measuring the share of international students, staff and co-authorship, as well as research collaboration within the Arab world),” the university said in a statement on Thursday.

"This is a testament to the world-class research environment we have cultivated here at KAUST. Our new strategy is already delivering, with new key deepening strategic partnerships across China, the US, Europe and locally in Saudi Arabia with the giga-projects,” said KAUST President Tony Chan.

Furthermore, the Top500 Committee has ranked the KAUST supercomputer 'Shaheen III' the most powerful in the Middle East and 20th in the world. Chan believes it will take KAUST further up the global rankings.

"We are super powering our research across all disciplines, which is going to significantly address key global and local issues, such as climate and sustainability, renewable energy, AI and future economy and smart health."

Saudi Arabian and UAE universities dominate the top 10 in the Arab University Rankings 2023. The ascension of KAUST and other Saudi universities in the Rankings reflects the Kingdom's unwavering focus and investment in research, development and innovation, the statement said.

New research suggests that Saturn’s rings may be older than they look — possibly as old as the planet.

Instead of being a youthful 400 million years old as commonly thought, the icy, shimmering rings could be around 4.5 billion years old just like Saturn, a Japanese-led team reported Monday.

The scientists surmise Saturn’s rings may be pristine not because they are young but because they are dirt-resistant.

Saturn's rings are long thought to be between 100 million and 400 million years old based on more than a decade of observations by NASA's Cassini spacecraft before its demise in 2017.

Images by Cassini showed no evidence of any darkening of the rings by impacting micrometeoroids — space rock particles smaller than a grain of sand — prompting scientists to conclude the rings formed long after the planet.

Through computer modeling, the Institute of Science Tokyo's Ryuki Hyodo and his team demonstrated that micrometeoroids vaporize once slamming into the rings, with little if any dark and dirty residue left behind. They found that the resulting charged particles get sucked toward Saturn or out into space, keeping the rings spotless and challenging the baby rings theory. Their results appear in the journal Nature Geoscience.

Hyodo said it's possible Saturn's rings could be somewhere between the two extreme ages — around the halfway mark of 2.25 billion years old. But the solar system was much more chaotic during its formative years with large planetary-type objects migrating and interacting all over the place, just the sort of scenario that would be conducive to producing Saturn's rings.

“Considering the solar system’s evolutionary history, it’s more likely that the rings formed closer to" Saturn's earliest times, he said in an email.
