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.”
Dubai’s private education sector has begun a full return to in-person learning, with schools, early childhood centres and universities reopening from April 20.
The phased move comes after strict safety preparations, with more than 200 early childhood centres already welcoming children back in recent days. In total, nearly 600 private institutions are now preparing to resume on-campus learning.
The reopening is being overseen by the Knowledge and Human Development Authority, which has worked closely with schools to ensure all health and safety measures are in place.
Officials say student and staff wellbeing remains the top priority, with extensive readiness checks, staff training and clear communication with parents carried out ahead of reopening.
Schools are also required to meet strict compliance standards, with ongoing inspections to ensure safety protocols are followed.
As students return, many institutions will run orientation and wellbeing sessions during the first week to help ease the transition back to classroom learning.
Families are being offered flexible options, including in-person classes, phased returns or continued distance learning where needed.
Authorities say the goal is to maintain high education standards while ensuring a safe, supportive environment for both students and teachers.
The UAE is already seeing a taste of summer, with temperatures climbing to 40°C in April, well above the usual seasonal range.
Typically, April temperatures hover between 32°C and 36°C, making this early spike unusual. But despite the rising heat, summer hasn’t fully arrived yet.
The country is currently in the Sarrayat season, a transitional period between spring and summer. This phase, which runs until early May, is known for sudden weather changes, including brief rain, strong winds, and dust storms.
Residents across the country can expect partly cloudy to cloudy skies on April 21, with dusty conditions at times, according to the National Centre of Meteorology (NCM).
There is also a chance of light rain over some coastal areas and islands, along with a slight drop in temperatures, especially in western coastal regions.
Winds will be light to moderate, shifting from southeasterly to northwesterly and northeasterly directions. At times, they may strengthen, reaching speeds of up to 40 km/h, causing dust to blow and reducing visibility in some areas.
Sea conditions will be slight to moderate, becoming rough at times in the Arabian Gulf, particularly toward the west, while remaining slight in the Oman Sea.
City temperatures today:
Dubai: High 35°C-Low 26°C
Abu Dhabi: High 36°C-Low 26°C
Sharjah: High 34°C-Low 22°C
Overall, the UAE continues to experience mixed spring weather, with dust, clouds, and occasional rain ahead of the hotter summer months. For now, the country remains in a transition phase, where heat and rain can occur on the same day, before the full intensity of summer sets in.
Dubai continues to attract professionals, families, and digital nomads seeking long-term apartment rentals, thanks to its strong economy, modern lifestyle, and world-class infrastructure.
However, for newcomers, finding the right apartment that fits both budget and lifestyle can feel overwhelming.
Here are some of the top areas in Dubai for long-term rentals, based on tenant preferences, amenities, and rental trends:
Think luxury
Dubai Marina Still one of the most in-demand expat hubs, prices vary a lot by tower, view, and furnishing. Typical rents: Studio: Dh55,000 – 110,000 1BR: Dh75,000 – 135,000 2BR: Dh110,000 – 200,000 3BR: Dh200,000 – 350,000
Market note: Median rent sits around Dh130,000 across unit types Waterfront views and newer towers push prices to the top end.
Palm Jumeirah (Palm Islands) This is a completely different tier—think luxury, beachfront, and limited supply. Typical annual rents: 1BR (apartments): Dh 140,000 – 200,000 2BR: Dh 250,000 – 350,000 3BR apartments: Dh 500,000 – 700,000
Best for families with quality living
Dubai Hills Estate: Green, peaceful, and family-focused. Popular for expat families, with top schools and long-term tenant stability.
Typical rents:
1BR: Dh80,000–120,000
2BR: Dh130,000–190,000
Jumeirah Village Circle (JVC): Affordable, community-driven living with parks and strong rental yields. Ideal for families seeking quiet suburban life.
Typical rents:
Studio: Dh45,000–65,000
1BR: Dh65,000–95,000

1BR: Dh95,000–140,000
Best for affordable rentals and value
A practical choice for professionals working in tech or nearby zones. Known for quieter living and relatively lower rents.
International City Remains one of Dubai’s most budget-friendly areas, popular for first-time expats or singles. Typical rents:
Studio: Dh30,000–45,000
1BR: Dh45,000–65,000
Al Barsha Well-connected (especially via metro) and still offers decent value compared to newer developments. Typical rents:
1BR: Dh70,000–100,000
2BR: Dh100,000–150,000
Discovery Gardens
This is firmly in the ‘affordable but spacious’ category. This neighbourhood is popular with expats who want bigger apartments without Marina-level prices.
Typical annual rents:
Studio: Dh 30,000 – 55,000
1BR: Dh45,000 – 72,000
2BR: Dh65,000 – 110,000
3BR: Dh90,000 – 120,000
Market reality:
Average rents sit around Dh 54,000 – 68,000/year, depending on unit type
Studios start at Dh 47,000, while 2BR units can go up to Dh 110,000
Still one of the best ‘space-for-money’ areas in Dubai, with larger layouts than newer buildings
How it compares
Discovery Gardens: Budget-friendly + bigger units + metro access
Cheaper than JVC and much cheaper than Dubai Marina
Trade-off: Older buildings + less ‘premium’ feel
For expats prioritising affordability, older central neighbourhoods such as Al Karama, Bur Dubai, and Deira continue to offer relatively lower rents compared to newer communities.
On the fringe
Further savings can be found in areas like Al Qusais, Muhaisnah, and outer residential zones, where rents are more accessible, but often at the cost of longer commute times and fewer modern amenities.
Typical budget range (older areas):
Studio: Dh28,000–50,000
1BR: Dh45,000–75,000
Why Dubai is still ideal for long-term rentals
Flexible payment options (1–4 cheques or annual upfront)
High-quality amenities (gyms, pools, parking in most buildings)
Strong, expat-driven rental market
Wide mix of luxury, mid-range, and budget communities
How to choose if you’re new to the city
With rising rents, the decision often comes down to trade-offs:
Want energy and convenience? – Business Bay, Downtown, Marina
Want space and community living? – Dubai Hills, JVC
Want affordability? – Silicon Oasis, International City, Deira
In 2026, several residents are compromising on location to gain space or save 15–25% on rent, especially with hybrid work becoming common.
