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: Parents can now attest school certificates in just 3 minutes

The UAE has introduced a major digital upgrade for parents and students, with the Ministry of Foreign Affairs and Sharjah Private Education Authority launching a new system that allows academic certificates to be issued and attested online in just minutes.

    Activated through the Dalil platform, the service combines certificate issuance and attestation into one streamlined digital process, removing the need for families to navigate multiple platforms or complete separate applications.

    Officials said the move is part of the UAE’s wider Zero Government Bureaucracy Programme, designed to simplify services, reduce paperwork and create a better, more user-friendly digital experience.

    Previously, parents often needed to complete up to three separate procedures involving schools, the Ministry of Foreign Affairs and UAE missions abroad. Under the new integrated system, the entire process can now reportedly be completed in around three minutes instead of taking up to six working days.

    The platform allows users to issue academic certificates through SPEA while simultaneously obtaining attestations from MoA and the relevant UAE mission in the destination country through one unified digital window.

    Officials described the initiative as another step towards building a fully connected digital government ecosystem focused on convenience, efficiency, and smarter public services.

    The new service is expected to particularly benefit families applying for university admissions, overseas transfers, and official educational documentation both inside and outside the UAE.

    Why is certificate attestation needed?

    School certificate attestation is the official process of verifying and certifying the authenticity of a student’s educational documents. This ensures that academic records and other important certificates are legally recognised by authorities in the UAE.

    The process is often required for several key purposes, including school admissions, university applications, student visa procedures and confirming the validity of educational qualifications for use inside the country.

    Forgot driving licence at home? UAE says digital copies are enough

    Drivers across the UAE no longer need to carry printed driving licences or vehicle registration cards while on the road, after the Federal Traffic Council confirmed that officially issued digital versions are now recognised as complete legal alternatives.

    According to the Ministry of Interior’s Federal Traffic Council, motorists can use electronic driving licences and vehicle registration cards through official smart applications, including the MOIUAE app and local authority platforms such as TAMM in Abu Dhabi.

    The move is part of the UAE’s wider push towards digital transformation and paperless government services, allowing residents to access official traffic documents instantly through their smartphones.

    Authorities said traffic officers can easily verify licence validity and vehicle ownership details electronically through integrated smart systems, reducing the need for physical document checks.

    The UAE already allows residents to access a wide range of official documents digitally through platforms such as UAE PASS, while many drivers now choose electronic-only delivery for renewed licences and vehicle registrations.

    However, authorities stressed that drivers must still ensure the digital documents are accessible through official government-approved applications when requested during inspections.

    Under current traffic laws, failing to carry a driving licence or vehicle registration card can result in fines of Dh400 for each violation.

    New roads, schools and flood systems coming to Abu Dhabi

    Abu Dhabi Investment Office and Abu Dhabi Projects and Infrastructure Centre have announced a massive new wave of infrastructure projects worth Dh55 billion across Abu Dhabi.

    The projects, scheduled across 2026 and 2027, will introduce new roads, schools, healthcare centres, flood control systems and community facilities as the capital continues its rapid expansion.

    Dh35 billion allocated to roads and transport

    The biggest share of the investment is going into transport infrastructure, with around Dh35 billion earmarked for 11 major road developments.

    Plans include:

    • More than 300km of new roads
    • Upgrades to tunnels and intersections
    • Expanded traffic networks across the emirate
    • Improved connectivity to key residential and commercial areas

    For residents navigating heavy traffic around areas such as Yas Island and central Abu Dhabi, the upgrades are expected to ease congestion and improve travel times.

    New schools, healthcare and sports facilities planned

    The remaining Dh9 billion will focus on social infrastructure projects aimed at improving daily life for residents.

    The plans include:

    • New schools and universities
    • Specialised healthcare centres
    • Sports and recreational facilities
    • Community-focused infrastructure developments

    Officials said several earlier public-private partnership projects in Abu Dhabi, including Zayed City Schools and the emirate’s LED road lighting programme, have already received regional industry recognition.

    Flood control and drainage systems upgrade

    Another Dh11 billion will be invested into water infrastructure projects, including:

    • Stormwater drainage systems
    • Flood prevention networks
    • Water storage facilities
    • New dams and flood control infrastructure

    The move comes after severe weather and flooding events across the UAE over the past year pushed drainage and climate resilience higher up the national agenda.

    The latest announcement signals Abu Dhabi’s continued push to modernise infrastructure, support population growth and strengthen quality of life across the emirate.
