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.”

Crackdown on Illegal paying guests: Dubai’s new shared housing law takes effect with fines up to Dh1m
Dubai’s new legislation governing shared accommodation officially came into effect on August 26. Applying across the entire emirate, including free zones and special development zones, the comprehensive framework is designed to eliminate dangerous, overcrowded, and unauthorised partition rentals while establishing formal licensing standards for communal living.
What qualifies as shared housing?
Under the law, shared housing is defined as any residential property where individuals or families occupy private designated living spaces while sharing common facilities like kitchens, bathrooms, and dining areas.
Who is permitted to rent out shared units?
The new framework strictly bans unauthorised subletting by tenants. A primary tenant can no longer rent out individual bedrooms, partitioned spaces, or bed spaces directly to roommates or third parties.
Only the following entities can legally offer shared housing:
- Registered Property Owners: Leasing spaces directly to occupants under formal contracts.
- Licensed Management Companies: Authorised operators contracted by the owner to run and lease the property.
- Licensed Operators Subletting Master Leases: Approved commercial entities leasing an entire property from the owner to sublet authorised units to tenants.
Penalties for violations
Authorities have introduced strict financial and operational consequences for non-compliance:
- Initial Fines: Dh500 up to Dh500,000, depending on the severity of the violation.
- Repeat Violations: Fines double for repeat offences committed within one year, capped at Dh1,000,000.
- Operational Sanctions: Authorities may suspend operations for up to 6 months, revoke commercial licenses, cancel permits, disconnect utilities, seize equipment, or order the direct evacuation of non-compliant properties.
Grace period & tenant protection
- Compliance deadline: Existing shared housing operators and property owners have until August 26, 2027, to obtain permits and bring their properties into full compliance.
- Protection from sudden eviction: If an operator’s permit is suspended or cancelled, authorities can grant occupants an interim stay period to secure alternative accommodation rather than facing immediate eviction.
Approved property/resident categories
The regulation permits shared accommodation across six distinct property types:
- Residential apartments
- Detached/standalone houses
- Residential complexes
- Mixed-use buildings
- Attached / adjoining houses
- Multi-storey buildings
Permitted occupant groups include families, single men, single women, university students, government personnel, and private sector corporate employees. Corporate and student housing provided directly by employers or educational institutions does not require individual tenancy contracts.
Students in UAE public schools, from Kindergarten to Grade 2, will not be given homework in the 2026-27 academic year, under a new Ministry of Education (MoE) policy.
The move aims to improve learning during school hours while creating a better balance between education and family life, the ministry said.
Instead of traditional homework, schools will encourage daily reading at home, with selected students encouraged to read with their parents at least once a day.
The approach is designed to strengthen children’s language and cognitive skills during their early years.
Less screen time for Grade 6
Grade 6 students will also see changes in the classroom. Screen use will be removed from subjects including Maths, Science, English and Arabic, with schools placing greater emphasis on group work and collaborative learning.
The MoE said it will continue assessing the effectiveness of digital tools in education.
Dubai Police ready for back-to-school
Meanwhile, Dubai Police have launched a back-to-school security and traffic plan to improve safety and ease congestion around schools.
The operation includes 253 patrols, 28 drones, mounted and bicycle patrols, and more than 200 student safety ambassadors.
A total of 775 police personnel will also engage directly with students, while awareness campaigns will be held with 16 government and private entities.
Authorities say keeping students safe is a shared responsibility involving police, schools, families and the wider community.
