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.”

KHDA releases new 2026 guide to end remote learning stress for Dubai parents

Published

on

Spread the love

In a move to protect family well-being and clarify the boundaries of home-based education, the Knowledge and Human Development Authority (KHDA) has launched a comprehensive new manual: The Parent Guide to Supporting Your Child During Distance Learning.

The core message of the guide is a massive relief for parents: You are not expected to be the teacher.  The Responsibility Split: Who Does What?

The KHDA is drawing a firm line in the sand to prevent parental burnout.

  • The school’s job: Teaching, planning lessons, delivering content, monitoring progress, and providing academic support.
  • The parents’ job: Providing a calm environment, maintaining consistent routines, and keeping the lines of communication open with the school.

Five priorities for success

The guide outlines five key pillars to help caregivers manage learning without feeling overwhelmed. While the full document is on the KHDA website, the strategy focuses on progress over perfection.

Tailored advice by age group

The KHDA recognises that a five-year-old and a 15-year-old have vastly different needs:

Early years and primary students: Younger children require hands-on support. The KHDA recommends focusing on short, simple activities rather than long blocks of screen time. Consistent routines and frequent, reassuring breaks are essential to prevent overstimulation.

Secondary and senior students: While older students are more independent, they are susceptible to “engagement fatigue.” They still require a clear daily structure and regular check-ins from parents to prevent them from feeling overwhelmed or losing focus on advanced coursework.

Students of determination: The guide provides targeted advice for students with additional learning needs, focusing on managing anxiety and behavioural barriers. It emphasises the need for a direct, transparent link between parents and the school’s inclusion team to ensure IEP (Individual Education Plan) goals are met at home.

The wellness check

A significant portion of the 2026 guide is dedicated to mental health. It provides practical steps to identify if a child is struggling with “engagement fatigue” or family pressures, offering a roadmap for parents to seek help from the school early, before the student falls behind.

How parents can access the guide

Dubai parents are encouraged to download the digital handbook directly from the KHDA website (https://web.khda.gov.ae). It serves as a living document that will be updated as distance learning technologies continue to evolve through 2026.

Abu Dhabi schools on notice: ADEK unveils 3-tier penalty system for remote learning failures

Published

on

Spread the love

Private schools in the UAE capital now face a strict new enforcement framework as the Department of Education and Knowledge (ADEK) moves to standardise the quality of remote education. Under a new three-tier classification system, schools failing to meet distance learning standards could face everything from written warnings to high-stakes license reviews.

The move aims to ensure that learning from home is not a second-class experience for students across Abu Dhabi.

The three levels of violations

Level 1: Administrative Lapses (The 48-hour warning) Minor procedural errors fall into this category. These are “behind-the-scenes” issues that don’t immediately harm the student’s day.

  • Examples: Delays in uploading attendance, straying from approved timetables, or late lesson plans.
  • The Penalty: A written notice to the school’s coordinator with a 48-hour deadline to fix the issue. The violation is permanently recorded in the school’s compliance history.

Level 2: Impact on student wellbeing (Fines and meetings)
This level targets schools where the quality of education or student welfare is directly compromised.

  • Examples: Lack of live interaction during lessons, poor monitoring of student welfare, or repeated complaints from parents.
  • The Penalty: Formal warning letters, mandatory hot seat meetings with ADEK leadership, financial penalties, and surprise follow-up inspections.

Level 3: Critical breaches (License at risk)
The most severe tier covers negligence and dishonesty.

  • Examples: Falsifying data, student safety incidents caused by negligence, or failing to deliver live teaching for extended periods without ADEK approval.
  • The Penalty: Maximum financial fines, direct administrative oversight by ADEK, public disclosure of the school’s status, and potential license reviews.

Quick tips for parents

For parents, this framework provides a formal teeth to their feedback. If a school is consistently skipping live sessions or failing to interact with students, ADEK now has a clear legal ladder to climb to force improvements. Here are a few things parents could do:

  • Keep a log: If your child’s school frequently misses live sessions, keep a dated log.
  • Communicate first: ADEK often looks for substantiated complaints, meaning you should try to resolve the issue with the school principal first.
  • Check compliance: Parents can soon expect Public Disclosure of schools that fall into Level 3, allowing for better-informed enrolment decisions for the 2026-2027 academic year.

ADEK stated that the framework is designed to strengthen accountability and ensure that distance learning remains aligned with student welfare.

By establishing clear rules on live teaching and attendance, the department is ensuring that the flexibility of remote learning does not come at the cost of educational excellence.

In a move to further slash waiting times for motorists, Dubai’s Roads and Transport Authority (RTA) has officially inaugurated a state-of-the-art vehicle testing and registration centre in Al Qusais.

Operated by Al Mutakamela, the new facility is designed to provide a “qualitative shift” in how residents and businesses handle their annual vehicle inspections and registrations.

High capacity, modern tech

The centre is built to handle heavy daily volume, featuring:

  • Seven dedicated lanes for light vehicles.
  • One specialised lane for motorcycles.
  • The latest automated inspection technologies to ensure every vehicle meets the UAE’s strict safety standards.

Focus on accessibility

The RTA emphasised that the Al Qusais centre has been specifically designed to be inclusive. Dedicated support staff are on hand to assist People of Determination and senior citizens (both Emiratis and residents), ensuring a seamless experience for those who may require extra help navigating the registration process.

Extended operating hours

One of the biggest advantages of the new Al Mutakamela centre is its extended operating schedule, catering to those who cannot visit during standard office hours.

  • Monday to Thursday & Saturday: 7:30am – 10:30pm
  • Friday: 7am – 12pm (Break for prayers) 3pm – 10:30pm
  • Note: The centre is closed on Sundays.

By adding eight new lanes to the local infrastructure, the RTA is significantly reducing the pressure on existing centres in the area, meaning shorter queues and faster “Pass” certificates for thousands of car owners.

Whether you are an individual car owner or a business managing a commercial fleet, the new Al Mutakamela centre offers a high-tech, high-speed solution to your registration needs.
