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.”

Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, has issued Law No. (4) of 2026 to regulate the management and occupancy of shared housing in Dubai.

The new law applies across Dubai’s private development zones and free zones and sets clear rules for property owners, authorised operators, and tenants involved in shared housing arrangements.

What the law aims to do

The legislation is designed to organise shared housing in the emirate and address issues such as overcrowding and informal accommodation. The law aims to:

  • Protect the rights of property owners and residents
  • Ensure safe and healthy living conditions
  • Prevent overcrowding and illegal housing practices
  • Address building and land-use violations
  • Promote fair rental practices
  • Support the stability and appearance of Dubai’s real estate market

Permit required for shared housing

Under the law, no individual or entity may allocate a property unit for shared housing without obtaining an official permit.

Permits will be issued and renewed according to rules set by Dubai Municipality, in coordination with Dubai Land Department and other authorities.

Properties must meet specific technical and safety requirements, including:

  • Maximum occupancy limits
  • Minimum space per resident
  • Adequate shared facilities
  • Compliance with building, health, fire, sanitation, security, and electrical standards

Permit validity and renewal

  • Permits are valid for one year and may be renewed for similar periods.
  • At the owner’s request, a two-year permit may be issued.
  • Renewal applications must be submitted at least 30 days before expiry.

Leasing rules

The law states that only the property owner or an authorised establishment can lease a shared housing unit.

Tenants or other parties are not allowed to sublease any part of the unit, ensuring better oversight and compliance with regulations.

Heavy fines for violations

Violating the law can result in fines ranging from Dh500 to Dh500,000.

If the same violation is repeated within one year, the penalty will be doubled, up to a maximum of AED1 million.

Authorities may also impose additional measures, including:

  • Suspension of activity for up to six months
  • Cancellation of the permit
  • Revocation of the commercial licence
  • Disconnection of public utilities
  • Eviction orders for non-compliant units

Oversight and implementation

Dubai Municipality will set detailed conditions for shared housing, including maximum occupancy levels, required space per resident, and necessary facilities. The authority will also determine which areas in Dubai are permitted for shared housing, based on urban planning, population density, infrastructure capacity, and neighbourhood characteristics.

The law applies to companies licensed to manage or lease properties on behalf of owners, including those operating in special development zones and free zones. However, collective labour accommodation is excluded from its scope.

When the law takes effect

The law will come into force 180 days after its publication in the Official Gazette, and any conflicting provisions in other legislation will be annulled.

Abu Dhabi Customs has issued a warning to the public about fraudulent SMS and iMessage messages circulating that impersonate the authority and well-known shipping companies in an attempt to steal personal information.

According to the authority, scammers are sending messages that appear legitimate, often claiming there is a shipment issue, customs fee, or a request to update delivery details. These messages usually include malicious links designed to trick recipients into providing sensitive information such as personal data, banking details, or login credentials.

Abu Dhabi Customs urged the public not to interact with these messages or open any links, stressing that fraudsters sometimes use phone numbers or names that falsely suggest they are associated with official entities to gain people’s trust.

The authority advised customers to avoid sharing personal information with unknown parties and to rely only on official channels to access services, track shipments, or obtain customs-related information.

Abu Dhabi Customs also reaffirmed its commitment to maintaining high cybersecurity standards and protecting customer data, noting that it works with relevant authorities to monitor and address digital fraud attempts.

Members of the public are encouraged to report any suspicious messages impersonating Abu Dhabi Customs through official channels, helping authorities raise community awareness and reduce phishing attempts.
