Revolutionary Brain Scan Detects Alzheimer's Before Symptoms Appear
Scientists have devised a world-first brain scanning technique that could identify signs of Alzheimer's disease, years before the symptoms appear. Using a technique called cortical disarray measurement (CDM) which analyses MRI scans to pinpoint more subtle signs of neurodegeneration, scientists are hoping to help millions with concerns about dementia. Currently, doctors diagnose diseases like dementia through a combination of questionnaires, which show memory problems and MRI scans. However, this process means people are diagnosed only when the disease has progressed. Through the new "precision diagnostic tool", doctors will be able to spot disruptions in the structure and function of the cortex, particularly those associated with functions such as memory, decision-making and language. "Our sophisticated diffusion analysis is based on a deep understanding of neuropathology, and the correlations between microscopic brain data and MRI analysis," British company Oxford Brain Diagnostics, which developed the novel technique, said in a statement. How does it work? As per the company, CDM is an all-in-one solution that is cloud native, non-invasive and monitors brain changes in patients across the multiple stages of adult life. CDM Insights processes clinical MRI scan data from both 1.5T and 3T scanners It then delivers outputs in the form of images and numerical values, usually presented as percentiles of a normative population distribution The proprietary technology has already been designated by the US Food and Drug Administration for use in the United States as a "breakthrough" device. Dr Steven Chance, former associate professor of neuroscience at Oxford, and Prof Mark Jenkinson, a leading expert in brain imaging, are the brains behind the company with UK investment firm BGF and the Oxford Technology & Innovations Fund providing the funding for the venture. Last month, researchers at Mass General Brigham also came up with an artificial intelligence (AI) tool capable of predicting brain decline in patients, years in advance. The AI tool analyses subtle changes in brain activity during sleep using electroencephalography (EEG) to make the prediction. During one of the studies, it correctly flagged 85 per cent of individuals who eventually experienced cognitive decline, with an overall accuracy of 77 per cent. According to the World Health Organization (WHO), about 55 million people worldwide live with dementia. Multiple studies have suggested that prior to the onset of cognitive impairment, alterations in behaviour and physiological functions may occur. Identifying these signals at the prodromal stages may potentially provide a better window for effective interventions.

NYUAD showcases cutting-edge innovations - all made in the Emirates
23 May 2025 00:45 MAYS IBRAHIM (ABU DHABI)New York University Abu Dhabi (NYUAD) showcased a suite of homegrown innovations at Make it in the Emirates in Abu Dhabi, including brain-controlled prosthetics, one-of-a-kind UAVs (unmanned aerial vehicles), and sustainable building materials. Mind-Controlled Prosthetics for Neurodegenerative ConditionsSpeaking with Aletihad, Abdul Basit, a research engineer at NYUAD, explained how a brain-controlled prosthetic arm developed at the university's eBRAIN Lab works. Using EEG (electroencephalogram) signals collected through electrodes placed on the scalp, the team is developing AI-driven systems that interpret brain activity and translate it into precise movements in a robotic arm. "This technology is primarily aimed at patients suffering from ALS (Amyotrophic Lateral Sclerosis) and MS (Multiple Sclerosis), paralysis or other neurodegenerative conditions for whom traditional EMG-based systems are not viable," Basit said. "We're also integrating gaze-tracking to make the interface more intuitive – allowing users to simply look at an object and think about an action to initiate it."The project is currently in the research and development phase. Basit noted that the team is currently working on optimising signal interpretation, reducing hardware complexity, and enabling real-time performance on edge added that the eBRAIN Lab is also developing AI-based MRI analysis for detecting MS lesions and brain tumours, which leverages multi-modal large language models to assist radiologists with diagnostic recommendations. Omni-Directional Drones and Humanoid Telepresence Robots At the Centre for Artificial Intelligence and Robotics (CAIR), Postdoctoral Associate Mahmoud Hamandi and his team developed the OmniOcta UAV – the world's first fully functional battery-powered omnidirectional drone using only fixed, unidirectional thrusters. Unlike traditional drones that tilt to manoeuvre, the OmniOcta can hover, rotate and fly at extreme angles, such as a 90° roll, thanks to its eight precisely angled thrusters calculated via a custom optimisation algorithm."This makes it ideal for inspection in confined spaces, as well as for physical interaction tasks like pushing objects or even unscrewing a lightbulb," Hamandi explained. "It's also entirely self-contained and robust, requiring no external power or mechanical tilting." Sustainable Construction Material From NYUAD's Advanced Materials and Building Efficiency Research Laboratory (AMBER Lab), research scientist Inderjeet Singh presented two game-changing sustainable construction materials. This includes SaltCrete, a magnesium-based cement developed at the AMBER Lab using reject brine from desalination and calcium carbide slag. This process not only reuses industrial waste but also captures carbon dioxide during curing, making it a potential carbon sink, according to other material is Limestone Calcined Clay Cement (LC3), which combines calcined clay and limestone to reduce emissions by 40% compared to traditional cement. "SaltCrete reduces emissions by around 50% and supports waste valorisation, while LC3 is currently being tested in marine environments to build eco-friendly sea walls that preserve biodiversity," Singh said.

Time for more home grown tea cultivation?
ROWS of tea plants could become a more familiar sight on the hills of Wales and other parts of the UK in the future. Scientists at Aberystwyth University have been using machine-learning to analyse the chemical make-up of tea grown in non-traditional areas, including Powys in mid Wales and Dartmoor in south west England. They hope their findings will help emerging tea growers in the UK to develop breeding strategies, cultivation practices and processing methods which suit climate conditions in this part of the world. The research team are currently working with Dartmoor Estate Tea in Devon which is known for its unique microclimate and soil diversity. The study is focusing on six varieties of tea which have been selected by the estate for their adaptability to diverse environmental conditions and their potential for chemical diversity. Speaking on International Tea Day 2025, Dr Amanda J Lloyd, a senior researcher in food, diet and health at Aberystwyth University's Department of Life Sciences, said: 'This study is contributing to the growing field of metabolomics by providing a comprehensive chemical profile of tea grown in a non-traditional region. Our findings offer new insights into the adaptability of tea plants and their potential for cultivation in emerging regions, contributing to global food security and agricultural diversification. Further research will now need to be carried out and should include multi-seasonal sampling, comparisons with traditional tea-growing regions, and analysis of processed tea to provide a more comprehensive understanding of tea chemistry.' The study's findings have been shared in an academic paper published in Metabolites, an international, peer-reviewed open access journal. Dr Lloyd and her team have also been working with Buckhall Farm near Knighton in Powys which is pioneering tea cultivation in high-altitude Welsh conditions. The project was part of the first phase of the SBRI Agri-Food Technology Challenge, funded by the Welsh Government. The work builds on an innovative portfolio of research at Aberystwyth University focused on tea's health benefits, sustainable cultivation and consumer behaviour. Among other ongoing studies is the Better Brain project, which is funded by Innovate UK and which is currently recruiting for a trial investigating the effects of a supplement containing green tea extract, ginseng and omega-3s on cognitive function in middle-aged and older adults. The study is led by the Well-being and Health Assessment Research Unit (WARU) at the University, working with colleagues from the Department of Psychology and using advanced electroencephalogram (EEG) technology to assess cognition and wellbeing. Professor Nigel Holt from the Department of Psychology and the University's Associate Pro Vice-Chancellor, International, said: 'Tea is not only comforting but increasingly reveals itself to be a cognitive ally. Our research is helping us understand the deep biochemical relationships between tea's compounds and mental function. Better Brain is particularly exciting because it bridges nutrition, psychology and neurophysiology.' For more information on our tea research or to participate in current studies, take a look at the WARU website.

American woman died of a mad-cow-like disease that lay dormant for 50 years: All you need to know
Image credits: Getty Images Sometimes life feels fine until the tragedy strikes and you realise that it was in the cards. An American woman recently died from an incurable prion disease that she had caught 50 years before. In a paper published on Wednesday in the journal Emerging Infectious Diseases, doctors revealed that the 58-year-old woman had developed a form of Creutzfeldt-Jakob disease (CJD) that she likely contracted through contaminated human growth hormone (HGH) treatments she received as a child. While the globally fatal disease is popular, the death presented the longest latency period ever documented for it. Creutzfeldt-Jakob disease Image credits: Getty Images Creutzfeldt-Jakob disease is a rare, fatal and rapidly progressive neurodegenerative disorder caused by abnormal prion proteins. Prions are proteinaceous infectious particles, a rogue protein that triggers normal proteins to misfold and form a clump and disturb brain function. Over time, the accumulation of bad prions destroys the brain and leads to symptoms such as dementia and death. What's concerning is that they are resistant to most standard methods of sterilisation that are used to kill other infectious agents like bacteria and viruses. How are prions caused? Prions can emerge sporadically with no clear reason. They can be caused by inherited mutations or can be transmitted through close contact with infected bodily fluids or brain matter. In the 1980s, doctors discovered that one could catch CJD through human growth hormone extracted from prion-infected cadavers. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Villas Prices In Dubai Might Be More Affordable Than You Think Villas In Dubai | Search Ads Get Rates Undo A decade later, it was learned that one could catch the disease via tainted beef from cows infected with their own version of the prion disease, which is nicknamed the mad cow disease. What are the symptoms of CJD? Image credits: Getty Images According to the National Institute of Neurological Disorders and Stroke, the main symptoms of CJD include cognitive troubles leading to dementia, involuntary muscle jerks, and lack of coordination of movements. While it can be diagnosed through a neurological exam, EEG, MRI and CSE tests, it has no cure as of now. What happened to the woman? According to the report, the woman initially visited doctors with tremors and trouble balancing. Once the symptoms of the disease started, her condition worsened, she was hospitalised, fell into a coma and died. An autopsy revealed her death's cause as CJD but ruled out genetic causes. Since she had received HGH treatment, it was considered to be the root cause of her illness by doctors. HGH is used to treat severe growth-related conditions in children and has been used for many years. In this case, the woman received her first treatment 51.3 years before her symptoms appeared. Since the US switched the collection of HGH from cadavers in 1977, thus reducing the risk of prion contamination, the timeframe of the woman's infection is around 48.3 years earlier. According to the authors, people who have a history of HGH treatment before 1977 must look out for similar delayed cases. 'Although the US CJD outbreak has slowed substantially, the potential for new cases remains,' they wrote. One step to a healthier you—join Times Health+ Yoga and feel the change
