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.”

No buses for now as UAE students return to classrooms

The UAE Ministry of Education has announced the temporary postponement of school bus services across the United Arab Emirates as students return to in-person learning.

The decision applies to all public and private nurseries, kindergartens, and schools. Officials said the move is aimed at allowing time to complete operational readiness in coordination with transport authorities and municipalities, ensuring services meet the highest safety standards.

The ministry confirmed that the situation will be reviewed weekly, with updates on the resumption of school transport to be shared through official channels.

The announcement comes shortly after authorities confirmed that in-person classes will resume from April 20, 2026, for students, teachers, and administrative staff across the country. Schools have already completed key preparations, including facility readiness, staff training, and updated safety procedures.

Private schools will also have the option to implement a hybrid learning model if required, depending on their readiness and in line with approved regulations. However, schools must ensure that teachers are not required to handle both in-person and remote classes at the same time, to maintain education quality and manage workloads.

Flexible attendance, transport fees waived

Schools will take a flexible approach to student attendance as transportation challenges continue during the current phase of reopening.

Authorities said schools will assess attendance on a case-by-case basis, considering individual family circumstances while ensuring the smooth functioning of the education system.

In public schools, no transport fees will be charged during this period. For private schools, any arrangements related to school transport fees will be handled by local education authorities in line with approved regulations.

Officials say all measures are aimed at supporting families while maintaining stability in the learning process.

Officials added that schools will remain ready to switch to alternative learning methods if needed, ensuring continuity of education under all circumstances.

Dubai eyes new law targeting kids’ e-scooter misuse

Authorities in Dubai are considering a new law that could hold parents legally responsible if their children misuse electric scooters, as part of efforts to improve road safety.

The proposal, currently being developed by Dubai Police in collaboration with the Roads and Transport Authority (RTA), aims to address growing concerns over unsafe riding and rising accidents involving minors.

Officials say electric scooters are no longer just recreational devices, with some being modified to reach dangerous speeds. Under the proposed law, parents could be held accountable if their children ride in restricted areas, break safety rules, or endanger themselves and others.

Authorities are also planning to introduce mandatory registration and number plates for all electric scooters. The move is expected to improve tracking, prevent misuse, and strengthen enforcement.

The proposal follows a rise in e-scooter-related incidents across the city. Recent figures show hundreds of accidents involving scooters and bicycles, including multiple fatalities and serious injuries, many of them involving children and teenagers.

Dubai Police have already stepped up enforcement, confiscating scooters and taking action against riders performing dangerous stunts in public areas.

Officials say the new measures aim to promote responsible behaviour, enhance accountability, and reduce risks linked to the growing use of micromobility devices.

No more fries and soda: UAE announces new school rules to promote healthy eating

The UAE has introduced a new national guide aimed at improving the quality of food and beverages available in schools.

The National Guide for Food and Beverages in the School Environment is designed to help schools, suppliers, and service providers offer healthier and more nutritious options to students throughout the day.

Officials say the guide focuses on building healthy eating habits among students while ensuring they receive the energy needed for academic performance. It promotes balanced, age-appropriate meals that support physical growth, improve concentration, and boost overall learning outcomes.

The framework also sets clear standards for food safety, preparation, and storage, while defining responsibilities for schools, local authorities, and food suppliers. It applies to all educational institutions, including public and private schools, as well as centres for People of Determination.

Schools to keep watch

Under the new rules, schools must ensure full compliance with nutrition and hygiene standards, while suppliers are required to meet strict guidelines and maintain valid permits. Parents will also have access to canteen menus, and schools must track and address any food-related complaints.

The guide introduces a structured system for monitoring and enforcement, with local authorities responsible for inspections, compliance checks, and reporting.

A list of banned items has also been outlined to encourage healthier choices. These include sugary drinks, fried foods, chocolates, processed meats, and products containing nuts.

Authorities say the initiative marks a major step toward creating a healthier school environment and supporting long-term student well-being across the UAE.
