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.”

Health alert: UAE issues warning after drug authority withdraws supplements over safety concerns

Published

Spread the love

Residents across the UAE have been urged to immediately stop using several health supplements and a laboratory product after the Emirates Drug Establishment (EDE) ordered their withdrawal from the market.

In four urgent circulars, the regulator announced the recall and ban of three food supplements and one medical product, citing safety concerns including unapproved ingredients, contamination risks and quality defects. The authority warned consumers not to purchase the named products, particularly through online sales platforms.

Businesses have also been instructed not to advertise, distribute, store or sell the affected items in pharmacies, medical warehouses, health shops or via e-commerce channels in the UAE.

Products that residents are advised to avoid

In its first alert, the EDE warned against an unauthorised supplement marketed as “Super Immune+”, stating that it contains unapproved ingredients, including dimethylaminoethanol (DMAE), molybdenum amino acid chelate, and boron citrate. The product was neither registered nor legally imported into the UAE.

A second circular ordered the withdrawal of WoundVite”, sold under the brand ZEN NUTRIENTS, after authorities identified the presence of a novel food ingredient not authorised under European regulations. The supplement had not undergone regulatory assessment in the UAE.

In a third notice, the EDE referenced a safety update issued by the U.S. Food and Drug Administration (FDA), coordinating with disease control authorities, regarding the recall of certain batches of “Rosabella Moringa Capsule” due to potential Salmonella contamination.

Separately, specific batches of the laboratory product “Isotonac-4” were recalled following a reported quality defect. The manufacturer and supplier have been instructed to implement an immediate withdrawal.

Public advisory

The EDE urged residents to verify the registration status of supplements and medical products before purchase and to avoid buying unverified health products from unofficial online sellers.

Consumers who have purchased any of the named items are advised to discontinue use immediately and consult a healthcare professional if they experience any adverse effects.

Authorities continue to monitor the market to ensure consumer safety and prevent the circulation of unauthorised health products.

BCD Global acquires second Dubai South site, targets Dh300mn revenue in H1 2026

International developer BCD Global has acquired a second development plot in Dubai South, accelerating its UAE expansion after its inaugural Dubai project was fully committed within weeks of launch.

The 70-year-old real estate group is targeting approximately Dh300 million ($81.7 million) in UAE revenue during the first half of 2026, marking its first meaningful earnings contribution from the market.

The latest acquisition follows BCD Global’s entry into Dubai last month with a freehold mid-market residential development in Warsan, where construction has already commenced. According to the company, all units were committed shortly after launch amid strong investor demand.

Scalable Platform Strategy

Chairman Dr. Angad Singh Bedi said the rapid absorption of the first project validated the group’s strategy of building a governance-led, scalable development platform rather than pursuing opportunistic transactions.

“The acquisition of a second site in Dubai South reflects our conviction in the long-term fundamentals of this market,” Bedi said. 

“We are building a platform designed for sustained capital deployment and disciplined growth.”

BCD Global has delivered more than 155 million square feet of real estate across over 300 projects spanning residential, mixed-use and large-scale developments in seven countries over seven decades.

Chief Executive Amit Puri described the move as part of a phased expansion strategy focused on structural demand drivers.

“Dubai remains one of the most resilient global property markets, supported by population growth, capital inflows and regulatory stability,” Puri said. 

“Dubai South represents the next phase of urban expansion, with infrastructure growth and demographic momentum supporting long-term housing demand.”

Market Backdrop

Data from the Dubai Land Department show total real estate transactions in Dubai reached Dh917 billion in 2025, up approximately 20% year-on-year. Average residential prices have climbed to around Dh1,597 per square foot, while rental yields in mainstream submarkets range between 6% and 8%, among the highest across major international cities.

Industry analysts project continued residential demand across the UAE, with close to 300,000 units expected to be delivered by 2028 amid sustained population growth and investor migration.

Pipeline and Regional Expansion

The newly secured Dubai South site forms part of BCD Global’s broader UAE pipeline. Another groundbreaking is scheduled next month, with construction on the second project expected to begin in the coming months.

The developer said its strategy centres on mid-market housing targeted at end-users and long-term investors, positioning itself away from short-term speculative segments.

From its Dubai base, BCD Global plans to expand across the Gulf, identifying Saudi Arabia as a priority growth market as it builds a diversified regional portfolio.

  • Dubai
  • Sharjah
  • Al Dhaid
  • Fujairah

Travellers can expect major time savings, including:

  • 57 minutes from Abu Dhabi to Dubai
  • 105 minutes from Abu Dhabi to Fujairah

A separate high-speed rail service is also planned, connecting Abu Dhabi and Dubai in just 30 minutes, with trains reaching speeds of up to 350 km/h.

Designed for families and daily commuters

Etihad Rail says the new passenger experience is built around comfort, reliability and flexibility.

Key features include:

  • Dedicated family seating areas
  • Strong Wi-Fi connectivity for remote work and business travel
