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.”

Spread the love

The Ministry of Human Resources and Emiratisation (MoHRE) has issued a final reminder to private sector companies with 50 or more employees: meet your mid-year Emiratisation targets by Monday, July 1, 2025, or face monthly fines.

Compliance Checks Begin July 1

Starting July 1, the ministry will begin verifying that:

  • Emirati employees are officially registered with approved pension funds
  • Monthly contributions are being paid in full

Companies failing to comply will be fined Dh9,000 per month for every unfulfilled Emiratisation slot for the first half of the year.

Support and Opportunities for Firms

MoHRE noted that the UAE’s strong economy and job market make it easier than ever to meet hiring goals. Support programmes like Nafis continue to assist companies in attracting qualified Emirati talent.

New Rule for Smaller Firms

The ministry also reminded companies with 20 to 49 employees, especially in 14 key economic sectors, that they are required to hire at least one Emirati by the end of 2025.

These sectors include:

  • Information & communications
  • Finance
  • Healthcare
  • Real estate
  • Manufacturing
  • Transportation & logistics
  • Hospitality
  • Education
    … and more.

More than 12,000 companies are affected by this rule, and electronic notifications have already been sent.

Act Now to Avoid Penalties

MoHRE urges companies to act without delay and ensure full compliance with Emiratisation policies as the government continues to build a more inclusive and diversified national workforce.

How these UAE cities are winning the war on mosquitoes with smart technology

Published

on

Spread the love

Abu Dhabi is taking mosquito control to the next level, using AI-powered smart traps that are transforming how the city monitors and manages mosquito populations, and the results are impressive.

Smarter, Cleaner, More Effective

Unlike traditional mosquito traps, Abu Dhabi’s smart traps don’t rely on chemicals. Instead, they mimic human body emissions, releasing carbon dioxide and a chemical scent similar to human skin, to attract blood-seeking female mosquitoes. Once close, a fan draws the mosquitoes into a net, safely trapping them for analysis.

Each trap is equipped with high-precision sensors and wireless connectivity, allowing it to transmit real-time data, including the number of mosquitoes caught, temperature, humidity, and time, to a central cloud-based system.

AI at Work for Public Health

Using artificial intelligence, the data collected is instantly analysed via smart dashboards. This enables mosquito control teams to identify high-risk areas, peak activity times, and how environmental factors like heat and humidity influence mosquito behaviour, all without the need for on-ground chemical spraying.

Game-Changing Results

Since the smart trap network launched in 2020, Abu Dhabi has seen:

  • 400% increase in mosquito capture efficiency (from 60 mosquitoes per traditional trap to 240 per smart trap),
  • A 42% drop in identified breeding sites,
  • Significant improvement in tracking mosquito populations and seasonal trends.

Dubai has Also Installed Smart Traps to Protect Residents

Dubai had earlier this year rolled out smart traps to protect its residents from insect-borne risks.

237 Smart Traps Installed Across Dubai

Dubai Municipality recently announced the deployment of 237 smart traps in key locations across the emirate, forming part of its proactive efforts to improve public health and enhance pest control systems.

The traps have been strategically positioned in:

  • Residential and commercial neighbourhoods
  • Industrial zones
  • Markets and public parks
  • Areas near water bodies and public facilities

Powered by the Sun, Driven by Data

What makes these traps truly smart? They run on clean solar energy and provide real-time mosquito activity data. By continuously monitoring insect populations, Dubai’s pest control teams can respond more quickly and accurately, especially during the winter season, when mosquito reproduction spikes due to favorable conditions.

A Unified, Tech-Driven Public Health Strategy

Together, Abu Dhabi and Dubai are setting a regional benchmark in sustainable, tech-powered public health protection. While Abu Dhabi’s network has already led to a 400% improvement in mosquito capture efficiency and a 42% drop in breeding sites, Dubai’s new deployment complements the national push toward smarter, cleaner pest control.

By harnessing innovation and sustainability, the UAE is building safer cities, where data, AI, and clean energy play a key role in protecting public health.

Why It Matters

With climate change, urban expansion, and the rise of pesticide-resistant mosquito strains, smarter, sustainable solutions are essential for protecting public health.
