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.”

UAE warns against sharing personal data on social media

The Cybersecurity Council (CSC) has warned the public against publishing or sharing sensitive or personal information on social media platforms, stressing that such practices can expose individuals to fraud and privacy breaches.

The Council said that personal data shared online can be exploited to design targeted scams and may result in violations of privacy in cyberspace. It urged users to exercise caution when posting information, noting that responsible online behaviour plays a critical role in reducing cyberattacks and fraudulent activities targeting individuals, companies and institutions.

According to the CSC, approximately 40 per cent of social media users have experienced privacy violations as a result of oversharing personal details about their lives and families. It cautioned that irresponsible sharing significantly increases the risk of theft, cyber fraud and identity theft.

The Council emphasised that even seemingly minor details shared publicly can be used in fraudulent schemes. Users were advised not to disclose home or workplace addresses, personal phone numbers, travel plans, or private family photographs.

Highlighting the importance of individual responsibility, the CSC stressed the need to safeguard personal data and secure social media accounts and mobile devices used for personal and professional purposes. It urged users to keep software updated, limit access to cameras, microphones and location services, create strong passwords, enable multi-factor authentication and adopt safe online practices.

The Council further advised the public to verify secure methods of sharing information, avoid unsecured platforms, monitor accounts regularly and exercise caution when responding to incoming messages, particularly as fraudsters increasingly employ advanced technologies to obtain financial and personal data.

Concluding its advisory, the CSC said cybersecurity remains a major challenge in the digital landscape and that preventive measures, responsible conduct and ongoing awareness are essential to addressing risks arising from rapid technological advancement.

The warning comes as part of the “Cyber Pulse” awareness campaign, launched by the Council for the second consecutive year on social media platforms. The initiative supports the UAE’s broader efforts to strengthen trust in the national digital ecosystem, promote cybersecurity culture and enhance digital awareness among families and individuals.

Sharjah Police warn motorists: Seconds of inattention can lead to fatal accidents

Sharjah Police have warned that even a few seconds of inattention behind the wheel can turn a routine journey into a tragedy.

The authority said negligence and distracted driving, including mobile phone use and other in-car distractions, remain among the leading causes of serious traffic accidents in the emirate.

According to traffic reports, brief lapses in concentration, particularly on highways and congested roads, significantly increase the risk of collisions that may result in severe injuries or fatalities.

Major Saud Al Shaiba and Captain Humaid Al Hammadi, Director of the Traffic Awareness Branch at Sharjah Police, stressed that distracted driving is not a minor offence.

Under Article 32 of the UAE Traffic Law, distracted driving, whether due to mobile phone use or any other cause, carries a Dh800 fine and four traffic black points.

Sharjah Police continue to urge motorists to comply with traffic regulations, remain fully attentive, and prioritise the safety of themselves and others, particularly during Ramadan.

The warning comes as part of the “Safe Roads during Ramadan” campaign, which highlights the importance of responsible driving during the holy month and reminds motorists that any distraction while driving can have devastating consequences.

Abu Dhabi Police have issued an advisory urging motorists to park only in designated areas near mosques during prayer times, particularly throughout Ramadan.

In a post on X accompanied by an awareness video, the authority stated that random parking near mosques during Taraweeh and other prayers is considered inappropriate behaviour that leads to congestion and disrupts traffic flow. Motorists were reminded to use designated parking facilities to ensure public safety and smooth movement of vehicles.

According to police, the most common violations recorded during peak prayer times include:

  • Double parking that prevents other vehicles from exiting
  • Parking on sidewalks, obstructing pedestrian movement
  • Blocking traffic lanes, especially near intersections and main roads
  • Remaining parked for extended periods after prayers results in congestion and delays

Abu Dhabi Police have called on the public to cooperate by adhering to traffic regulations to avoid fines and ensure safe, orderly access to mosques during Ramadan.
