    • AI ‘Chef Aiman’ to create data-driven flavour combinations

    • Aims to reduce food waste and boost sustainability





    DUBAI (Reuters) – In Dubai, your dinner might soon come with a side of source code.

    WOOHOO, a restaurant that bills itself as “dining in the future”, is set to open in September in central Dubai, a stone’s throw from the world’s tallest building, the Burj Khalifa.

    Food at WOOHOO will be assembled by humans, for now, but everything else – from the menu to ambience to service – will be designed by a culinary large-language-model called “Chef Aiman.”

    Aiman – a portmanteau of “AI” and “man” – is trained on decades of food science research, molecular composition data and over a thousand recipes from cooking traditions around the world, said Ahmet Oytun Cakir, one of WOOHOO’s founders.

    While Chef Aiman can’t taste, smell or interact with his dishes like a chef normally would, the model works by breaking cuisine down to its component parts like texture, acidity and umami, and reassembling them into unusual flavour and ingredient combinations, according to Aiman’s developers.

    These prototypes are then refined by human cooks who taste the combinations and provide direction, in an effort led by renowned Dubai-based chef Reif Othman.

    “Their responses to my suggestions help refine my understanding of what works beyond pure data,” Aiman explained, in an interview with the interactive AI model.

    The goal, Aiman’s creators say, is not to supplant the human element of cooking but to complement it.

    “Human cooking will not be replaced, but we believe (Aiman) will elevate the ideas, creativity,” said Oytun Cakir, who is also chief executive of hospitality company Gastronaut.

    Aiman is designed to develop recipes that re-use ingredients often discarded by restaurants, like meat trimmings or fat, he said.

    Longer term, WOOHOO’s founders believe Aiman could be licensed to restaurants across the globe, reducing kitchen waste and improving sustainability.

  • Physicists take step toward a holy grail for electron spins

    Physicists take step toward a holy grail for electron spins

    For decades, ferromagnetic materials have driven technologies like magnetic hard drives, magnetic random access memories and oscillators. But antiferromagnetic materials, if only they could be harnessed, hold out even greater promise: ultra-fast information transfer and communications at much higher frequencies – a “holy grail” for physicists.

    Now, researchers have taken a meaningful step towards utilizing antiferromagnets for new technologies. In “Spin-filter tunneling detection of antiferromagnetic resonance with electrically-tunable damping,” published July 10 in Science, they describe their innovative approach for both detecting and controlling the motion of spins within antiferromagnets using 2D antiferromagnetic materials and tunnel junctions.

    Both types of materials contain atoms that act like tiny individual magnets, each having “spin.” In a ferromagnet, all of these atomic spins are aligned, producing an external magnetic field. In an antiferromagnet, atomic spins cancel when they are added up, so no external magnetic field is produced. That’s why it’s difficult to not only detect the motions of spins within antiferromagnets but also control the motion of their spins.

    Previously, detections of the spin dynamics in antiferromagnets occurred with millimeter or larger samples, “not something that really scales down to any kind of useful device scale,” said co-corresponding author Dan Ralph, F.R. Newman Professor of Physics in the College of Arts and Sciences and a member of the Kavli Institute at Cornell. “What we’ve done is make micrometer-scale devices where we can see strong signals, using tunnel junctions to be able to detect the spin motions electrically – and that’s nearly a factor of 1,000 smaller than what’s been done before.”

    Tunneling is a sort of quantum mechanical leaking of an electron through a barrier that a classical particle wouldn’t be able to get through; it’s not a direct flow of electrons across, but a penetration of an electron wave function as it goes through a barrier, Ralph said. “Electrons can do funny things,” he said, adding that tunneling is a common device used in all kinds of technologies.

    When the spins in the antiferromagnet change their directions inside a tunnel junction, this changes the electrical resistance associated with the tunneling electrons, providing a way to measure the spin dynamics.

    This electrical detection works at very high speeds. Most technologies are not equipped to detect at that frequency.

    “This is one of our breakthroughs: that we’re using this tunneling behavior, which is this quantum mechanical electron behavior, to really read out these extremely fast oscillations,” said co-corresponding author Kelly Luo, a former Presidential Postdoctoral Fellow and Honorary Kavli Postdoctoral Fellow at Cornell, now an assistant professor at the University of Southern California.

    Their breakthroughs came in part by interweaving two fields: 2D materials and spintronics, also known as spin electronics, said lead author Thow Min Jerald Cham, M.S. ’21, Ph.D. ’24.

    To help control the spins within the 2D antiferromagnet, the researchers used a mechanism known as spin-orbit torque. They passed a charge current through a material to make a spin current that can interact with the magnet, to apply a torque to the magnet and make it move.

    “We were mainly searching for a way to manipulate the spins so that we could detect the 2D layers separately, and we couldn’t really distinguish which layer was doing what. Then we came up with this idea, where we could break the symmetry by twisting the layers,” said Cham, who is now a postdoctoral scholar at California Institute of Technology.

    With this geometry, we can use applied currents with spin-orbit torque to apply a force to just one of the spin layers and not the other, a first step for controlling the spin dynamics,” Ralph said.

    “Our studies shows that antiferromagnetic materials have great potential,” the researchers wrote, “for realizing nano-oscillators for high-frequency applications”— an avenue they continue to explore.

    Other co-authors are Xiaoxi Huang, postdoctoral associate in Ralph’s lab; Daniel G. Chica and Xavier Roy, Columbia University; and Kenji Watanabe and Takashi Taniguchi, National Institute for Materials Science, Japan.

    Support for the research included funding from the National Science Foundation and the U.S. Department of Energy.

  • Online support package empowers parents to improve dental health of young autistic children

    Online support package empowers parents to improve dental health of young autistic children

    A new, free, online support package aims to empower parents of young autistic children to look after their dental health – and reduce levels of tooth decay and surgery. 

    It follows a study led by the University of Leeds, which highlights the oral health challenges faced by autistic children. The research team has collaborated with autistic youngsters, their families, and early-years professionals to co-design the support package, following parents’ calls for autism-specific advice on how to improve oral health habits. The toothPASTE website provides parents with practical, tailored solutions focusing on: toothbrushing, going to the dentist, and eating and drinking. It features videos, downloadable resources, and a forum where parents can share their experiences and advice. 

    Challenges faced by parents with autistic children 

    One in four autistic children have tooth decay by the age of five – similar to the wider childhood population – but they are less likely to visit the dentist and twice as likely to need dental treatment under general anaesthetic. 

    Poor oral health in childhood has lifelong impacts. Establishing optimal oral health habits – brushing twice a day with fluoride toothpaste, limiting sugary foods and drinks, and going to the dentist – are critical. However, for families of autistic children, building and keeping these habits can be more difficult. This is due to additional challenges such as communication difficulties, sensory sensitivities, and restricted or repetitive behaviors. 

    For example, sensory differences can make toothbrushing painful or repulsive. Dental visits can also be overwhelming, with bright lights, unfamiliar smells, strange tastes, and unexpected sounds or touch. Some autistic people experience social communication differences, making it hard for them to express if they are in dental pain. In addition, repetitive behaviours or strong preferences may lead to limited diets, often high in sugar, which can increase the risk of tooth decay. 

    The impact of decay is far-reaching, affecting self-esteem, speech, eating, sleeping, and quality of life. But it can also affect a child’s school attendance, impacting negatively on life outcomes. 

    Tooth decay is a major health problem, but it is preventable. Establishing optimal habits in early life provides the foundations for long term oral health and reduces the impact of tooth decay on autistic children, their families, the NHS and wider society.” 


    Peter Day, Professor of Children’s Oral Health and Consultant in Paediatric Dentistry at Leeds

    He added: “In the long term, we hope to see a reduction in the number of autistic children that need dental care in hospital, and we hope our findings will help early-years professionals and dental teams support parents with their autistic child’s oral health needs.” 

    Anne-Marie Kilgallon, of Mirfield, West Yorkshire, has two autistic sons, both of whom had multiple teeth extracted under general anaesthetic when they were still in primary school. 

    She said: “To be told your children need teeth removing at the ages of eight and 10 is incredibly hard. 

    “Had this kind of support been around back then, I truly believe Tolan and Fredi wouldn’t have had to go through that. We are just one example – there are so many families facing the same challenges. 

    “If we’d had access to the right education and support around oral health, tailored to their additional needs, I honestly believe we could have avoided such a traumatic experience for both of our boys.” 

    Designed with parents, for parents 

    Dr Amrit Chauhan, Lecturer in Qualitative Methodology and Autism-related Oral Health Research within the School of Dentistry and a Chartered Psychologist at Leeds, who co-led the research, said: “We want to help parents feel more confident in caring for their young autistic children’s teeth. That’s why families of autistic children have been involved from the start of the study, and we have very much been led by them on what they want.” 

    “We know that most parents already have a good idea of what they should be doing, like brushing twice a day with fluoride toothpaste – it’s more about finding practical ways to get there. 

    “Every family is at a different point in their journey, and every child’s needs are unique. So, on the website, we break things down into small, manageable steps. We take a gentle, gradual approach, recognising that for some children, making even one small change might take weeks or even months – and that’s okay.” 

    The Leeds team collaborated with researchers from the University of Manchester and University of Sheffield on the project, which was funded by the National Institute for Health and Care Research (NIHR) and West Yorkshire NHS Integrated Care Board. It is hoped the project will help reduce health inequalities. 

    Much-needed support 

    Nikki Pickles, family support manager for AWARE (Airedale and Wharfedale Autism Resource), whose son is autistic, led the project’s Patient and Public Involvement group. She said: “We work with hundreds of families every year and challenges with toothbrushing and oral health are extremely widespread. Parents frequently share their daily struggles and concerns with us. 

    “It can feel like a very lonely battle. They’re desperate for support, so we think this will be an amazing asset. There is no other resource like this. 

    “It is easy to navigate and provides useful strategies, plus advice based on the most up-to date oral health research, all specifically tailored for our cohort of families. We are really excited and super proud to be part of the project.” 

    Underpinned by inclusive research 

    The toothPASTE website was created following in-depth research featuring interviews with minimally-verbal autistic children. They used Talking Mats – visual communication aids – to describe their sensory difficulties, with one child describing toothpaste as an “explosion in the mouth”. 

    The study also involved interviews with families and early-years professionals to explore both the barriers to, and the factors that support, the development of optimal oral health habits. Co-design workshops followed, with parents, early-years professionals and national stakeholders. 

    Dr Shannu Bhatia, President, British Society of Paediatric Dentistry (BSPD), said: “BSPD welcomes the toothPASTE website with tools to help parents and carers of autistic children and young people navigate a journey of good oral health. 

    “The research that has gone into the toothPASTE website has enabled the development of a set of well-targeted tools to support neurodivergent young people and will really help their parents and carers. 

    “We know that supporting neurodivergent children and those with additional sensory requirements can present specific challenges, so guidance to help all children achieve healthy teeth and gums, is something BSPD is keen to support.” 

    The website is accessible to all, which means it can be used by those without a formal autism diagnosis, and it will be continuously refined to ensure its effectiveness. The team will continue working with families, dental professionals, the National Autistic Society, Autistica and Government bodies to share their findings and undertake further research to maximise the site’s effectiveness. 

    Case study

    Anne-Marie Kilgallon’s two autistic sons were just eight and 10 and when they had to have multiple teeth extracted under general anaesthetic. 

    Had the toothPASTE support package been around when they were little, she believes it could have prevented their pain and resulting surgery. 

    The 46-year-old, who co-founded The Whole Autism Family support group with husband Martin in 2015, said: “I wish we’d had that resource when the boys were tiny: it would have made such a huge difference to our lives.” 

    She added: “To be told your children need teeth removing at the ages of eight and 10 is incredibly hard. 

    “Had this kind of support been around back then, I truly believe Tolan and Fredi wouldn’t have had to go through that. We are just one example – there are so many families facing the same challenges. 

    “I know lots of children that have had teeth extracted, and not just one tooth: Tolan had five, Fredi had seven. I know another child that had eight. 

    “But that’s the end result. Had we been educated on how to deal with their specific issues around oral health and had this resource, I honestly believe that we wouldn’t have had to put our children through these traumatic surgeries.” 

    Life-changing for families 

    Anne-Marie, of Mirfield, West Yorkshire, says the website will be life-changing for the hundreds of families she works with, whose children’s dental health is a major problem. 

    She said: “Tooth brushing is probably in the top 10 concerns for parents we support. It’s a battle and one they have to deal with every single day. I’ve had mums in floods of tears, not knowing what to do. 

    “As parents, we’re all trying to do our very best, but I think I think lots of professionals that work with children like Fredi and Tolan could do with more support or more understanding of some of the battles that we face.” 

    Tolan, now 15, is non-speaking and Fredi, now 13, uses echolalia – repeating others’ speech – to communicate, although he doesn’t always fully understand the words he is saying. Both boys have learning disabilities and attend a SEN school in Leeds. 

    When they were younger, the family used a picture system to help with learning and to communicate. They helped the children understand aspects of daily life such as taking off their coats, or how to use cutlery. Both boys had extreme oral sensitives, which resulted in a restricted diet, using food as a reward and an extreme dislike of toothbrushing. 

    They were eventually referred to a dentist who specialised in SEND (special educational needs and disability), who suggested strategies such as changing toothbrushes; oral sensitivity exercises, non-flavoured toothpaste, distractions and brushing at different times of the day. 

    Instant, accessible support 

    Anne-Marie said: “These are all covered on the website, which looks amazing. What that does is it gives everyone immediate access to expert advice and peer support, rather than having to wait for a referral or just suffering in silence. 

    “I love the videos on there. I found them really useful, and I think lots of the families that I support would find them extremely beneficial too. I think there should really be a pack, when you get a diagnosis for a child, and for that to have a sign pointing to the website would be absolutely amazing.”

  • Tiny rice plants could help astronauts grow food in space

    Tiny rice plants could help astronauts grow food in space

    The dream of living beyond Earth demands fresh food far from our planet. The Moon-Rice project is pioneering this vision by experimenting with future-proof crops for space. One day, this initiative could supply nutritious food to astronauts and people living in harsh environments on Earth.

    Today, space missions depend on supplies from Earth. These include ready-to-eat meals that lack fresh ingredients. Such meals often miss essential nutrients that the human body needs, especially during long missions.


    For deep space exploration, we must grow food rich in vitamins and fiber. The Moon-Rice project aims to create such crops. Their goal is to sustain life in deep space missions.

    “Living in space is all about recycling resources and living sustainably,” said Marta Del Bianco, a plant biologist at the Italian Space Agency. “We are trying to solve the same problems that we face here on Earth.”

    Tiny rice is key for space food

    Dr. Del Bianco noted that the main challenge: crop size. Many dwarf rice types are still too large for space farming. “What we need is a super-dwarf, but this comes with its own challenges.”

    “Dwarf varieties often come from the manipulation of a plant hormone called gibberellin, which can reduce the height of the plant, but this also creates problems for seed germination. They’re not an ideal crop, because in space, you just don’t have to be small, you must also be productive.”

    Since space farming demands high-yield crops that are compact, scientists face the tough task of balancing plant size with productivity.

    United efforts for innovation

    In addition to the Italian Space Agency, the research involved the work of experts from three Italian universities.

    The University of Milan has a strong background in rice genetics, the University of Rome ‘Sapienza’ specializes in crop physiology manipulation, and the University of Naples ‘Federico II’ has a rich heritage in space crop production.

    “We started this four-year project nine months ago, so it’s very much a work in progress, but the preliminary results we have now are really promising,” said Del Bianco.

    Tiny rice plants with more protein

    Scientists at the University of Milan have discovered tiny rice varieties. These grow only 10 centimeters tall.

    “Researchers at the University of Milan are isolating mutant rice varieties that can grow to just 10 cm high, so they’re really tiny and this is a great starting point,” said Del Bianco. “At the same time, Rome has identified genes that can alter the plant architecture to maximize production and growth efficiency.”

    In addition to compactness, the team is enhancing rice protein levels. Meat production will not be practical in space, so protein-rich crops are vital.

    Testing rice plants in fake gravity

    According to Dr. Del Bianco, the team investigated how the rice plants would respond to microgravity. This type of research helps ensure the plants can survive space conditions.

    “We simulate microgravity on Earth by continually rotating the plant so that the plant is pulled equally in all directions by gravity. Each side of the plant gets activated continuously and it doesn’t know where the up and down is,” she said.

    “It’s the best we can do on Earth because, unfortunately, doing experiments in real microgravity conditions – i.e. in space – is complex and expensive.”

    Fresh food helps mental health

    Fresh food does more than nourish the body. It also boosts mental health.

    “Watching and guiding plants to grow is good for humans, and while pre-cooked or mushy food can be fine for a short period of time, it could become a concern for longer-duration missions,” said Del Bianco.

    Astronauts need both physical and psychological support during their missions. Their health directly affects mission success. Mistakes in space can be costly or even deadly.

    “If we can make an environment that physically and mentally nourishes the astronauts, it will reduce stress and lower the chances of people making mistakes. In space, the best case of a mistake is wasted money, and the worst case is the loss of lives,” said Del Bianco.

    Space rice could help farmers

    The Moon-Rice project has benefits beyond space. It could help farmers on Earth too.

    “If you can develop a robust crop for space, then it could be used at the Arctic and Antarctic poles, or in deserts, or places with only a small amount of indoor space available,” said Del Bianco.

    The research will be presented at the Society for Experimental Biology Annual Conference in Antwerp, Belgium, on July 9, 2025.

    Nicholas Hoult Got Asked About Bleaching His Hair Blonde And His 9-Word Response Says It All

    Nicholas Hoult, famously, is a brunette. However, the guy is not afraid to change his hair at all. He shaved his head for one of the best action movies of all time, Mad Max: Fury Road. Then, he did it again to play Lex Luthor in James Gunn’s Superman, which is set to premiere on the 2025 movie schedule on July 11. Now, he’s bleached his hair blonde for a new role, and his nine-word response about it says it all.

    In the midst of promoting the release of Superman, Nicholas Hoult has been talking a lot about his hair, or lack thereof. Part of that is because he shaved it off to play Lex Luthor. However, it’s also a topic of conversation because bleaching it blonde marked another dramatic change in his look. When ET asked him if there was anything he wouldn’t do for a role while referencing his blonde hair, the actor responded with the following nine words:

  • Breakthrough Listen Releases Results for 27 Eclipsing Exoplanets

    Breakthrough Listen Releases Results for 27 Eclipsing Exoplanets

    We live in an exciting time of technological innovation and breakthroughs in astronomy, cosmology, and astrophysics. This is similarly true for the Search for Extraterrestrial Intelligence (SETI), which seeks to leverage advances in instrumentation and computing to find evidence of “technosignatures” in the Universe. While the scope has expanded considerably since Cornell Professor Frank Drake and colleagues conducted the first SETI experiment over sixty years ago (Project Ozma), the vast majority have consisted of listening to space for signs of possible radio transmissions.

    A prime example is Breakthrough Listen (BL), a project launched by Breakthrough Initiatives in 2016 and the largest SETI experiment ever mounted. BI combines radio observations from the Green Bank Observatory and the Parkes Observatory with visible light observations from the Automated Planet Finder. In a recent study, an international team of astronomers examined 27 exoplanets selected from the Transiting Exoplanet Survey Satellite (TESS) archive and examined them for signs of artificial radio signals that went silent as they passed behind their stars.

    The study was led by Rebecca Barrett, a SETI researcher and recent Masters of Science (Astrophysics) graduate from the University of Southern Queensland (UniSQ). She was joined by researchers from the UniSQ Center for Astrophysics, the SETI Institute, the Berkeley SETI Research Center, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Astronomy and Space Science, the Centre for Astrophysics and Supercomputing(CAS) at the Swinburne University of Technology, the International Centre for Radio Astronomy Research (ICRAR), and the Square Kilometer Array Observatory (SKAO).

    The field of SETI has grown considerably in the past six decades, reflecting our expanding knowledge of the cosmos and astrophysical phenomena. Per the NASA Technosignature Report (released in 2018), the list of potential technosignatures includes gravitational waves (GWs), neutrinos, directed energy (optical communications or propulsion), and more. Nevertheless, surveys in the radio spectrum are still at the forefront of SETI investigations because the technology has a proven track record as a cost-effective means of communication. Moreover, radio waves are easily detected since they experience minimal scattering as they pass through planetary atmospheres and the interstellar medium (ISM).

    The field has also been bolstered by the spate of exoplanet discoveries that have taken place in the past twenty years. To date, more than 5,900 exoplanets have been confirmed in over 4,400 planetary systems, with thousands more awaiting confirmation. For their study, the team carefully selected a frequency band of radio data from a large set of observations made by BI from 2018 to 2022. The team ensured that these observations’ field of view (FoV) corresponded to a selection of 27 confirmed and candidate exoplanets detected by NASA’s Transiting Exoplanet Survey Satellite (TESS).

    Specifically, the team looked for indications of potential radio signals that were interrupted as these planets passed behind their respective stars (occulted). As Barrett told Universe Today via email:

    Occultations could provide a unique opportunity to search for and localise technosignatures. Hypothetically, if a transmitting exoplanet were to pass behind its host star, the signal should be interrupted, resuming when it re-emerges. A signal could thus potentially be isolated from the surrounding noise and RFI by subtracting emission received from the system during eclipse from emission during transit. This concept will be explored in future works.

    Using occultations to detect and confirm targets for SETI technosignature searchers has gained popularity in the last decade. However, the focus has been on planet-planet occultation and signal spillover, whereas Barrett and her colleagues explored planet-star occultation. Their work was based on Barrett’s 2023 Master’s thesis, which established the first limits using targets of interest (TOIs) designated by TESS. Unfortunately, all 27 TOIs were attributed to radio frequency interference (RFI), ruling out the possibility of technological activity.

    Murriyang, CSIRO’s Parkes radio telescope at the Parkes Observatory.

    Nevertheless, this study is the first case where planet-star occultations were used for technosignature searches and will serve as a benchmark for similar SETI surveys in the near future. Said Barrett:

    I personally plan to commence a PhD in 2026, where I hope to continue developing tools that will aid in the search for intelligent life. I was very fortunate to work alongside some of the leading experts in the field during this project, and will undoubtedly do so again in the future! I would hope that this work could inspire further SETI investigations toward exoplanets during occultation and help spur the development of an efficient method for isolating unique emissions that could be applied as a background check in mainstream transiting exoplanet surveys.

    The preprint of their paper was published online by the University of Cambridge Press and is being reviewed by the Publications of the Astronomical Society of Australia.

  • Psychological stress drives ovarian tumor metastasis through NR3C1 and NUPR1

    Psychological stress drives ovarian tumor metastasis through NR3C1 and NUPR1

    This new article publication from Acta Pharmaceutica Sinica B, discusses how a psychological stress-activated NR3C1/NUPR1 axis promotes ovarian tumor metastasis.

    Ovarian tumor (OT) is the most lethal form of gynecologic malignancy, with minimal improvements in patient outcomes over the past several decades. Metastasis is the leading cause of ovarian cancer-related deaths, yet the underlying mechanisms remain poorly understood.

    Psychological stress is known to activate the glucocorticoid receptor (NR3C1), a factor associated with poor prognosis in OT patients. However, the precise mechanisms linking NR3C1 signaling and metastasis have yet to be fully elucidated.

    The authors of this article demonstrate that chronic restraint stress accelerates epithelial-mesenchymal transition (EMT) and metastasis in OT through an NR3C1-dependent mechanism involving nuclear protein 1 (NUPR1). Mechanistically, NR3C1 directly regulates the transcription of NUPR1, which in turn increases the expression of snail family transcriptional repressor 2 (SNAI2), a key driver of EMT. Clinically, elevated NR3C1 positively correlates with NUPR1 expression in OT patients, and both are positively associated with poorer prognosis.

    Overall, this study identified the NR3C1/NUPR1 axis as a critical regulatory pathway in psychological stress-induced OT metastasis, suggesting a potential therapeutic target for intervention in OT metastasis.

    Vitamin A Deficiency: 5 warning symptoms of Vitamin A deficiency |

    Amidst the fad diets, superfoods, and supplements world, some very fundamental yet critical nutrients tend to go unnoticed, and Vitamin A is one of these. While iron, vitamin D, and B12 deficiencies are a constant source of media coverage, Vitamin A deficiency tends to be silently neglected, even though it strikes millions of people, especially in third-world nations.Vitamin A is essential to have good eyesight, a healthy immune system, good skin, and good cell growth. However, most people, particularly pregnant women and children, are prone to its deficiency without even knowing. World Health Organization states that Vitamin A deficiency is the most common cause of preventable blindness in children and raises the risk of disease and death significantly.So why isn’t this talked about more? A part of the issue is the gradual onset of symptoms. They tend to show up as aches and pains or skin problems and not become severe until later. By the time individuals take action, the deficiency may have done permanent damage.Following are 5 important Vitamin A deficiency symptoms that can be dangerous if ignored:

    Night blindness

    Difficulty seeing in dark or low light conditions is one of the earliest and most precise signs of Vitamin A deficiency. Difficulty seeing in dark or low light conditions, or night blindness, occurs because Vitamin A plays an important role in the formation of rhodopsin, a pigment in the eye used to see in low light. If it is not treated, night blindness can lead to total loss of vision.

    Dry eyes and corneal damage

    Vitamin A maintains moist eyes and guards against the surface tissues. When individuals lack sufficient amounts of it, they can suffer from dry, inflamed eyes, and even severe xerophthalmia, a condition that can result in permanent blindness. The cornea could get cloudy or form ulcers, which can hurt and become irreversible if not acted on immediately.

    Frequent infections

    Vitamin A enhances the immune system by keeping mucous membranes intact in the respiratory, digestive, and urinary systems. Individuals with Vitamin A deficiency have an increased vulnerability to infections like pneumonia, measles, and diarrhea. Indeed, research has indicated that VAD elevates mortality from infectious diseases, particularly in children.

    Dry, scaly skin

    Vitamin A is very important in the regeneration of skin. Lack of it can cause rough, dry, or scaly skin on the arms, legs, and face. This sign is confused with eczema or other skin diseases. With time, the skin becomes more susceptible to wounds and takes longer to heal.

    Delayed growth and development

    In children, Vitamin A deficiency can also affect physical and cognitive development. It has an impact on bone growth, immune response, and tissue repair, all of which are important at early childhood. Learning and growth can be stunted in children with chronic Vitamin A deficiency.Vitamin A deficiency is more prevalent and perilous, than most are aware. It lurks in the shadows, usually undiagnosed until serious illness strikes. The good news is that it’s preventable and curable by way of a nutritionally balanced diet packed with leafy greens, carrots, sweet potatoes, eggs, and dairy, or by supplementation as needed.Raising awareness of this quiet deficit may save sight, enhance immunity, and even save lives, particularly among the world’s most at-risk communities.
