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.”

Begging scams and illegal butchers under Dubai Police watch this Eid

Dubai Police has warned residents against dealing with beggars and itinerant butchers during Eid Al Adha, revealing that authorities arrested 50 people linked to begging and illegal slaughter activities during last year’s holiday period.

Police said some individuals attempt to exploit the festive season and people’s generosity through traditional street begging, online scams and unlicensed slaughter services operating in residential areas.

Brigadier Ali Salem Al Shamsi, Director of the Criminal Phenomena Department at Dubai Police, said anti-begging campaigns are being intensified in cooperation with strategic partners to tackle illegal activities that negatively impact public safety and the emirate’s image.

According to police, begging methods now extend beyond mosques and public markets to include electronic begging, fake donation requests and fraudulent humanitarian appeals shared online.

Authorities warned that some beggars use children, elderly individuals, sick people and people of determination to gain sympathy and collect money illegally.

Dubai Police also urged residents to donate only through officially recognised charities and approved humanitarian organisations to ensure funds reach legitimate causes.

Alongside the anti-begging warning, police cautioned the public against hiring itinerant butchers during Eid Al Adha, citing serious hygiene and public health risks.

Officials said illegal butchers often slaughter animals in unsanitary locations using unsterilised equipment, moved from house to house without proper cleaning or health supervision.

Residents have been urged to report beggars or illegal butchers by calling 901 or through the “Police Eye” feature on the Dubai Police smart app. Cases of online begging and fraud can also be reported through the e-Crime platform.

Abu Dhabi Police has announced full security and traffic readiness ahead of the Eid Al Adha holiday, unveiling a comprehensive plan aimed at ensuring public safety, easing congestion and strengthening emergency response across the emirate during one of the busiest periods of the year.

The force said security and traffic patrols will be intensified across major roads, commercial centres, parks, Eid prayer grounds and public gathering areas expected to see heavy footfall during the holiday.

Police presence will also increase in densely populated neighbourhoods and entertainment destinations across Abu Dhabi, Al Ain and Al Dhafra to support smoother traffic movement and maintain public safety throughout the celebrations.

Authorities confirmed that the central operations room will remain operational 24/7 to handle emergency calls and coordinate rapid response efforts in cooperation with strategic partners.

Special traffic management plans and diversion scenarios have also been prepared to minimise congestion during Eid activities and events across the emirate.

Police urged motorists to follow traffic regulations, avoid speeding and reckless driving, and maintain safe road behaviour throughout the holiday period.

The force also warned against dangerous celebratory behaviour, including drifting, illegal street racing and reckless stunts near residential areas.

Families were additionally advised to supervise children closely and avoid the use or trade of fireworks due to the serious safety risks associated with improper handling during Eid celebrations.

Abu Dhabi Police said awareness campaigns and field inspections will continue throughout Eid to strengthen community safety and ensure residents and visitors enjoy a safe and secure holiday across the emirates.

CBSE extends Class 12 answer sheet request deadline again after portal glitches

  1. The Central Board of Secondary Education (CBSE) has once again extended the deadline for Class 12 students to apply for scanned copies of their evaluated answer sheets following ongoing technical issues affecting the online portal.

The board confirmed that the application deadline, originally scheduled to close on May 24, has been extended to midnight on May 25, 2026.

The move comes after several students reported difficulties completing applications after the introduction of a new on-screen marking and post-result processing system. Many candidates said payments were deducted even though their requests were not successfully submitted.

According to CBSE, the extension is intended to give students additional time while technical issues continue to be addressed.

The board also announced that the schedule for re-evaluation requests will be released separately and added that the portal will remain open for at least two days after the final scanned answer sheets become available.

The board said students affected by payment errors will receive refunds directly through their original payment methods. Candidates who paid less than the required amount will be contacted separately regarding balance payments.

CBSE also clarified that scanned copies of evaluated answer sheets will still be issued without students needing to submit fresh applications.

The ministry has also sought a detailed report into the technical failures, including server downtime and operational shortcomings, as scrutiny over the examination process continues.
