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.”

UAE Ramadan 2026: Residents protected as price hikes are banned on 9 essential foods, Dubai launches inspections

With Ramadan 2026 around the corner, UAE residents are being assured that essential grocery prices will remain protected, as authorities ban unauthorised price increases on nine staple food items and ramp up inspection campaigns across Dubai.

Grocery bills tend to rise during Ramadan as families prepare for Iftar and Suhoor, but officials say strict monitoring is already underway to prevent unfair price hikes and checkout discrepancies.

Which items cannot increase in price?

Retailers are not allowed to raise prices, without prior government approval, on these essential goods:

  • Cooking oil
  • Eggs
  • Dairy products
  • Rice
  • Sugar
  • Poultry
  • Legumes
  • Bread
  • Wheat

Any attempt to increase prices on these items without approval can lead to immediate enforcement action.

What Dubai inspectors are checking

Inspection teams are visiting supermarkets, cooperatives and grocery stores across the emirate to:

  • Ensure shelf prices match what customers pay at checkout
  • Verify that promotions are genuine and clearly explained
  • Monitor stock levels to prevent artificial shortages
  • Stop any unauthorised price increases

Authorities say inspectors often pick random items from shelves and scan them at the counter to confirm prices match exactly.

If there’s a difference, it’s treated as a violation.

What happens if retailers break the rules?

Penalties can range from warnings to fines between Dh500 and Dh100,000. In serious or repeated cases, stores could face temporary closure.

Officials have stressed that protecting consumers during Ramadan is a priority, especially as household spending increases during the Holy Month.

Can prices differ between stores?

Yes — price differences between retailers are legal under UAE market competition rules. However, charging more at checkout than the displayed shelf price is not allowed.

Authorities have also instructed retailers to clearly display terms for loyalty-based promotions to avoid confusion.

Monitoring stock levels

In addition to price checks, regulators are monitoring supply chains to ensure shelves remain stocked and to prevent panic buying or artificial shortages.

Officials say compliance rates across UAE retailers remain high.

As Ramadan approaches, residents are being reminded that protecting the spirit of fairness and transparency in the market is a shared responsibility, and that any pricing concerns can be reported to authorities.

Dubai motorists: New RTA road slashes commute time by 60 per cent

Dubai drivers using Sheikh Mohammed bin Zayed Road and Sheikh Zayed bin Hamdan Al Nahyan Street can now expect significantly shorter journeys, after the Roads and Transport Authority (RTA) completed Al Rowaiyah Street, a new 3.5-km direct link between the two major highways.

For daily commuters, the biggest impact is time. Travel time to Sheikh Mohammed bin Zayed Road has been reduced from around 10 minutes to just four minutes, a 60 per cent drop, easing congestion during peak hours.

Faster access for Silicon Oasis, Academic City

The new corridor improves entry and exit points for several high-density residential and education zones, including Dubai Silicon Oasis, Nadd Hessa, Dubai International Academic City and Warsan 4.

For residents commuting to work across Dubai, the direct connection removes the need for longer internal detours, helping streamline morning and evening traffic flows.

Increased capacity and smoother traffic flow

RTA confirmed that traffic capacity along Sheikh Zayed bin Hamdan Al Nahyan Street has increased by up to 40 per cent following the upgrade.

As part of the project, the former KHDA roundabout has been converted into a signalised intersection, improving safety and reducing bottlenecks at a previously congested junction.

For commuters navigating daily traffic across Dubai, the new Al Rowaiyah Street link is designed to deliver one key outcome faster, safer and more direct journeys between two of the city’s busiest arterial roads.
