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.”

In a major UAE government move, His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE, and Ruler of Dubai, has announced the creation of a new Ministry of Foreign Trade and renamed the Ministry of Economy to the Ministry of Economy and Tourism.

Taking to the social media platform X, Sheikh Mohammed said the decisions were made in consultation with His Highness Sheikh Mohamed bin Zayed Al Nahyan, President of the UAE.

“Brothers and sisters, after consultation with my brother, the President of the State, may God protect him, and with his approval, we announce today several changes in the UAE government as follows: The Ministry of Foreign Trade was established in the UAE government and the name of the Ministry of Economy is changed to Ministry of Economy and Tourism,” the Dubai Ruler wrote in his post.

Key announcements include:

The establishment of a new Ministry of Foreign Trade, with Dr. Thani Al Zeyoudi appointed as the minister.
The Ministry of Economy is now renamed the Ministry of Economy and Tourism, to reflect its broader scope. Abdullah Bin Touq Al Marri will continue to lead it.
The National Artificial Intelligence System will become an advisory member of the Cabinet, starting January 2026. It will also join the Ministerial Council for Development and the boards of all federal entities and government-owned companies.

The integration of AI into key decision-making bodies aims to enhance policy efficiency, provide real-time technical advice, and support future-focused governance across sectors.

Sheikh Mohammed emphasised that the move aligns with the UAE’s ongoing commitment to innovation, agility, and strategic leadership at all levels of government.

Dubai-India Travel: Several flights cancelled as Air India cuts services amid safety concerns

Planning to fly from Dubai to India soon? Check your flight status before heading to the airport.

Air India has advised travellers to confirm in advance following the cancellation of several flights, including those from Dubai.

The move is part of a broader cutback in international operations, as the airline conducts safety inspections across its Boeing 787 Dreamliner fleet. The inspections follow a recent tragic crash involving one of the aircraft.

Among the cancelled international routes are:

AI906 (Dubai–Chennai)
AI2204 (Dubai–Hyderabad)

Passengers flying on other airlines and looking to connect to their hometowns via Air India should be aware of the suspension of domestic and other international routes, such as:

AI308 (Delhi–Melbourne)
AI874 (Pune–Delhi)
AI456 (Ahmedabad–Delhi)
AI2872 (Hyderabad–Mumbai)
AI571 (Chennai–Mumbai)

The cancellations come after Air India announced a 15 per cent cut to international flights operated by its widebody aircraft, effective until at least mid-July. The airline said this temporary reduction is necessary due to ongoing safety inspections following the tragic crash of flight AI171 last week.

Flight AI171, a Boeing 787 Dreamliner heading from Ahmedabad to London Gatwick, crashed shortly after takeoff, killing 241 people on board and approximately 30 people on the ground. Only one person on the aircraft survived. Authorities continue to investigate the incident.

In a statement, Tata Group-owned Air India said that 26 of its 33 Boeing 787-8 and 787-9 aircraft have passed inspections and have returned to service. The airline said the cuts are meant to ensure stable operations, improve efficiency, and minimise passenger inconvenience.

UFC CEO Dana White has confirmed the first six explosive matchups, including a can’t-miss main event featuring former middleweight champion Robert Whittaker taking on Reinier de Ridder, the surging Dutch fighter making waves across the division.

The co-main event sees rising star Aaron Pico make his highly anticipated UFC debut in a five-round featherweight showdown against the undefeated Movsar Evloev.
