M42 announces breakthrough results for its AI-powered tuberculosis screening
Conducted in collaboration with Capital Health Screening Centre (CHSC) in Abu Dhabi, part of the M42 group, the study is among the largest real-world clinical validations of an AI-driven healthcare solution to date, analyzing over one million chest X-rays (CXRs) to evaluate the efficacy and scalability of AI in TB screening.
The study assessed AI Radiology in Screening TB (AIRIS-TB), M42's cutting-edge AI model engineered to streamline routine tuberculosis screenings, allowing radiologists to focus on more complex or urgent cases. AIRIS-TB demonstrated exceptional performance, achieving an Area Under the Receiver Operating Characteristic Curve (AUROC) of 98.5% - a clear indicator of its high efficiency in triaging CXRs for TB.
With an estimated 10.8 million people falling ill from TB and a total of 1.25 million people dying from it in 2023, according to the World Health Organisation (WHO), and recent reports of TB returning to being the world's leading cause of death from a single infectious agent, M42's AIRIS-TB demonstrates the potential of AI solutions delivering real-world impact. AIRIS-TB reported an unprecedented 0% false-negative rate for tuberculosis-specific cases across the full dataset – an achievement that reinforces its safety and reliability as a workflow automation tool. In practical application, the model has the potential to safely automate up to 80% of routine CXR assessments, directly alleviating radiologist workload pressures, minimising the risk of human error, and delivering significant cost efficiencies in high-throughput low-prevalence settings. Presently, CXR review remains labor-intensive and prone to oversight and error, potentially leading to missed or delayed diagnoses, with a prior study stating a 26.6% increase in missed findings when radiologists double their annotation speed, and a rise in errors after 9 hours into their shift.
Importantly, AIRIS-TB delivered consistently strong performance across a wide range of demographic groups, including variations in gender, age, HIV status, income levels, and a diverse population covering six WHO regions, highlighting the model's robustness, fairness and generalisability across diverse global populations. These results underscore AIRIS-TB's potential to significantly enhance clinical workflows and drive earlier, more equitable screening of TB in high-volume programmes worldwide.
Dimitris Moulavasilis, Group CEO of M42, said, "This landmark study marks a pivotal moment in the potential power of AI in the global fight against tuberculosis. Our AIRIS-TB model stands as a compelling testament to the unmatched accuracy, safety and scalability that AI can deliver, particularly in resource-limited settings where there is a shortage of radiologists and the need to tackle TB is greatest. In regions with a high prevalence of TB, we now have a scalable technological solution that can bridge the divide, expand radiologist capacity and help save lives. These results signal the transformative role AI can play in reshaping global public health and redefining how healthcare is diagnosed, delivered and experienced worldwide.'
Dr. Laila Abdel Wareth, CEO of Capital Health Screening Centre, added, "The outcomes of this study reaffirm that AI models like AIRIS-TB can not only match – but safely surpass – human-level accuracy and efficiency in clinical practice. By automating high-volume, routine screenings with precision, we are equipping radiologists to concentrate on complex and high-risk cases, unlocking greater diagnostic capacity. This shift holds immense potential to elevate patient outcomes, streamline healthcare delivery and bolster public health infrastructure on a global scale."
The study underwent rigorous peer review and ethical oversight by the Department of Health – Abu Dhabi, ensuring transparency, accountability, and the highest standards of clinical integrity. Its publication in a leading scientific journal reinforces M42's position as a global pioneer in AI-led health solutions and solidifies the UAE's growing prominence as a global, data-driven hub for cutting-edge medical innovation and technology.

Google commits $1 billion for AI training at US universities
6 Aug 2025 23:13 SAN FRANCISCO (REUTERS) Alphabet's Google on Wednesday announced a three-year, $1 billion commitment to provide artificial intelligence training and tools to US higher education institutions and than 100 universities have signed on to the initiative so far, including some of the nation's largest public university systems such as Texas A&M and the University of North schools may receive cash funding and resources, such as cloud computing credits towards AI training for students as well as research on AI-related topics. The billion-dollar figure also includes the value of paid AI tools, such as an advanced version of the Gemini chatbot, which Google will give to college students for hopes to expand the programme to every accredited nonprofit college in the US, and is discussing similar plans in other countries, Senior Vice President James Manyika said in an declined to specify how much Google is earmarking in direct funds to external institutions relative to footing its own cloud and subscription announcement comes as rivals like OpenAI, Anthropic and Amazon have made similar pushes around AI in education as the technology pervades in July pledged $4 billion to bolster AI in education evangelising their products to students, tech firms further stand to win business deals once those users enter the workforce.A growing body of research has mapped concerns around AI's role in education, from enabling cheating to eroding critical thinking, prompting some schools to consider bans. Manyika said Google had not faced resistance from administrators since it began to plot its education initiative earlier this year, but "many more questions" about AI-related concerns remain. "We're hoping to learn together with these institutions about how best to use these tools," he said, adding that the insights could help shape future product decisions.

OpenAI to provide ChatGPT Enterprise 'essentially at no cost' for US federal workforce
OpenAI chief executive Sam Altman said his company was partnering with the US government to make the ChatGPT Enterprise version available to the federal workforce 'at essentially no cost'. The company said the partnership was in line with President Donald Trump's recently announced AI Action Plan, which seeks to bolster the US lead in the global race for artificial intelligence dominance. Federal agencies that decide to participate in the partnership will be able to use ChatGPT Enterprise 'for the nominal cost of $1 per agency for the next year'. OpenAI describes ChatGPT Enterprise as containing some of the company's 'best AI models and capabilities', and says that it is used by more than three million people. Target, Lowes, JetBlue, Bain & Company, T-Mobile and Amgen are listed as ChatGPT Enterprise clients. 'By giving government employees access to powerful, secure AI tools, we can help them solve problems for more people, faster,' a statement from the San Francisco-based company read. The partnership with the US government is the latest move among technology companies seeking to gain an upper hand in the competitive US AI landscape. Although research on AI began in the 1960s, recent advancements in computer processing power, coupled with iterations of AI solutions such as ChatGPT in 2022, led to an explosion of interest, investments and start-ups in the tech ecosystem. Companies like Alphabet, Anthropic, DeepSeek and Claude, among others, are all vying for industry dominance. As to government partnerships, OpenAI is pursuing similar deals around the world. In May, brief negotiations took place between the UAE and OpenAI that might eventually lead to the company's ChatGPT Plus AI chatbot being available to all residents free of charge, though a final deal has not been reached.
