NYU Abu Dhabi researchers find mysterious new set of waves in Sun

Researchers from NYU Abu Dhabi’s (NYUAD) Centre for Space Science have discovered a new set of waves in the Sun that, unexpectedly, appear to travel much faster than predicted by theory.

In the study, ‘Discovery of high-frequency-retrograde vorticity waves in the Sun’, published in the journal Nature Astronomy, the researchers, led by Research Associate Chris S. Hanson, detailed how they analysed 25 years of space and ground-based data to detect these waves. The high-frequency retrograde (HFR) waves, which move in the opposite direction of the Sun’s rotation, appear as a pattern of vortices (swirling motions) on the surface of the Sun and move at three times the speed established by current theory.

The interior of the Sun and stars cannot be imaged by conventional astronomy (e.g. optical, x-ray etc.), and scientists rely on interpreting the surface signatures of a variety of waves to image the interiors. These new HFR waves may yet be an important puzzle piece in our understanding of stars.

Complex interactions between other well known waves and magnetism, gravity or convection could drive the HFR waves at this speed. “If the HFR waves could be attributed to any of these three processes, then the finding would have answered some open questions we still have about the Sun,” said Hanson. “However, these new waves don’t appear to be a result of these processes, and that’s exciting because it leads to a whole new set of questions.”

This research was conducted within NYUAD’s Centre for Space Science in collaboration with the Tata Institute of Fundamental Research (TIFR) and New York University, using NYUAD and TIFR’s computational resources. By studying the Sun’s interior dynamics – through the use of waves – scientists can better appreciate the Sun’s potential impact on the Earth and other planets in our solar system.

“The very existence of HFR modes and their origin is a true mystery and may allude to exciting physics at play,” said Shravan Hanasoge, a co-author of the paper. “It has the potential to shed insight on the otherwise unobservable interior of the Sun.”

Final Rentals taps 13,000-car GCC fleet in new AUTORENT Alliance

British car rental technology platform Final Rentals has announced a strategic partnership with AUTORENT, one of the Gulf region’s largest vehicle rental and leasing operators, as it accelerates expansion across the GCC.

The agreement gives Final Rentals access to AUTORENT’s fleet of more than 13,000 vehicles operating across the UAE, Saudi Arabia, Bahrain and Oman, significantly strengthening the company’s regional presence.

The move marks a homecoming of sorts for Final Rentals, which launched its first operations in the UAE in 2021 before growing into a global platform serving customers in more than 65 countries.

The company’s growth has been rapid. Annual bookings surged from just 1,900 in 2021 to more than 139,000 in 2025. Momentum has continued this year, with 148,065 bookings recorded in the first five months of 2026 alone, already surpassing its full-year 2024 performance.

“The UAE is where Final Rentals started,” said CEO Ammar Akhtar.

“Many of the lessons that shaped our technology and business model were learned here. Expanding our Gulf operations is both a strategic and symbolic step as we return with a much larger international network and greater scale.”

Founded in Wales in 2016, Final Rentals operates a digital marketplace that connects travellers with local vehicle rental providers across Europe, the Middle East, Africa and the Americas.

For AUTORENT, the partnership supports its digital transformation ambitions by enhancing online booking capabilities and improving customer access to its vehicle network across the region.

The announcement comes as economic ties between the UK and Gulf countries continue to strengthen, with discussions ongoing around a proposed UK-GCC free trade agreement aimed at boosting trade and investment.

Industry observers say the Gulf remains an attractive destination for international technology companies due to its rapidly growing digital economy, advanced infrastructure and strategic position linking Europe, Asia and Africa.

What El Nino means for the UAE: Hotter summer, more humidity and rainfall in coming months

The UAE could experience hotter-than-normal and wetter-than-normal weather in the coming months as El Niño conditions strengthen across the tropical Pacific Ocean, according to the National Centre of Meteorology (NCM).

In its latest seasonal outlook, the NCM said there is a 98 per cent probability of El Nino conditions continuing between July and November 2026, with temperatures and rainfall across the UAE expected to range from near-average to above-average levels.

The forecast is based on conditions in the Nino 3.4 region of the tropical Pacific Ocean, a key climate indicator used by meteorologists worldwide. The latest sea surface temperature anomaly in the region is 0.5°C above normal, officially placing it within El Nino territory.

What is El Nino?

El Nino is a natural climate pattern caused by unusually warm ocean temperatures in the central and eastern Pacific. Although it occurs thousands of kilometres away, it can influence weather systems across the globe, including the UAE and other countries in the region.

Historically, El Nino events have been associated with higher temperatures, increased humidity, heavier rainfall in some regions, and more extreme weather patterns worldwide.

What could it mean for the UAE?

While the UAE is not among the regions most severely impacted by El Nino, forecasters say residents could see:

  • Higher-than-normal temperatures
  • Increased humidity levels
  • Greater chances of rainfall compared to seasonal averages
  • More variable weather patterns during the second half of the year

The NCM stressed that climate conditions are continuously monitored and forecasts will be updated monthly based on the latest international weather models and observations.

For now, residents should prepare for a potentially hotter and more humid summer as the climate phenomenon strengthens.

Emirati International Arbiter Abdullah Murad Al Mazmi has been appointed to the officiating panel for the 2026 FIDE World Rapid and Blitz Team Championships, one of the biggest events on the global chess calendar.

The championship will take place in Hong Kong from June 16 to 22 and is expected to feature many of the world’s leading grandmasters, including world number one Magnus Carlsen.

Al Mazmi’s selection highlights the growing international recognition of Emirati chess officials. He currently serves as Chairman of the Arab Chess Federation’s Arbiters Committee and Tournament Director of the prestigious Sharjah Masters International Chess Championship.

Speaking about the appointment, Al Mazmi said he was proud to represent the UAE at one of chess’s most prestigious global events. He described the selection as a reflection of FIDE’s confidence in Emirati arbiters and their ability to officiate at the highest international level.

He added that the role carries significant responsibility and offers a valuable opportunity to exchange expertise with some of the world’s top chess officials while showcasing the progress of UAE chess on the global stage.

The appointment marks another milestone for Emirati representation in international sports administration and reinforces the UAE’s growing presence in the world of chess.
