Wearable device simulating CT scans enables continuous heart, lung monitoring
The belt-like device, attached around a patient's chest, uses ultrasound and works like a CT scanner. Rather than taking an isolated snapshot, it can produce a series of dynamic, high-resolution images of the heart, lungs and internal organs over time, giving doctors deeper insight into a patient's condition.
The breakthrough device has been developed at the University of Bath in collaboration with Polish technology company Netrix and is detailed in a recent publication in IEEE Transactions on Instrumentation and Measurement.
The soft, skin-conforming sensor array is placed directly on a patient's chest and uses sophisticated ultrasound computed tomography (USCT) to generate images of the heart and lungs in real time, tracking changes in organ function and structure continuously over hours or even days.
Currently, patients with conditions such as heart failure, pneumonia, or respiratory distress often require multiple imaging procedures that are intermittent, disruptive, and radiation-intensive. The new device allows for non-invasive, bedside monitoring—minimising the need for transport, improving comfort, and enabling earlier detection of deterioration or recovery.
Crucially, the device is designed with patient comfort in mind. Its soft, flexible materials make it suitable for long-term wear, and its wireless data transmission capabilities allow integration with hospital monitoring systems. Future iterations may even offer AI-assisted analysis for clinicians, identifying warning signs before they're visible to the human eye.
Beyond hospitals, this technology opens the door to remote monitoring in home care settings, particularly for elderly patients or those with chronic cardiopulmonary diseases. It may also reduce the healthcare burden by preventing unnecessary hospital admissions through early intervention.

MagRail Set to Revolutionise Port Freight at Kandla
Arabian Post Staff -Dubai DP World, Deendayal Port Authority and Polish tech firm Nevomo have formalised an agreement to pilot Nevomo's MagRail system—a self-propelled, electric linear‑motor freight train—on a 750‑metre stretch at the port in Kandla. Signed on 15 July 2025 by top executives from each organisation, the deal marks India's first experiment with autonomous magnetic rail freight within an operational port environment. The partnership will pilot MagRail technology on existing railway tracks to autonomously transport containerised and bulk goods. Powered by electric linear motors, MagRail wagons eliminate diesel use, promising reductions in logistics time, operational costs and CO₂ emissions. The trial is designed to enhance port-hinterland connectivity and support India's broader logistics modernisation under the National Logistics Policy and the PM‑Gati Shakti agenda. ADVERTISEMENT DP World, a global supply chain specialist, is leading efforts to integrate this advanced freight solution. The Deendayal Port Authority—a significant multi‑cargo terminal under central government jurisdiction—is hosting the pilot to assess real‑world viability. Nevomo will provide its proprietary MagRailBooster system, designed for seamless integration with existing port rail networks. This three‑way collaboration reflects an alignment of private innovation and public logistics priorities. According to Sushil Kumar Singh, chair of the port authority, the initiative represents 'a strategic advancement in port infrastructure, enhancing capacity and operational efficiency to support growing cargo demands,' signalling strong institutional backing. Sultan Ahmed bin Sulayem, DP World's group chairman and CEO, emphasised that MagRail will 'reduce transit times and optimise infrastructure use,' adding value for customers while promoting sustainability. Nevomo's CEO, Przemek 'Ben' Paczek, said the project would 'showcase MagRail's real‑world potential in boosting freight efficiency,' reflecting confidence in the technology's applicability to closed‑loop logistics systems. Harj Dhaliwal, Nevomo's Chief Business & Capital Programmes Officer, was credited with advancing the partnership. European rail specialists have already acknowledged MagRail's promise in port and metro-campus settings. Industry experts note that MagRail addresses several persistent bottlenecks in freight logistics: it offers rapid container shunting without the need for diesel road vehicles, improves yard cycle times, and integrates with existing rail infrastructure, minimising capital expenditure. The pilot's green credentials also align with global port decarbonisation targets. Situated at Kandla, which recently welcomed a large satellite terminal by DP World with a TEU capacity of 2.19 million, the trial supports the port's expansion strategy. Officials hope that MagRail can help optimise operations across the new and existing facilities. Planning documents suggest a phased implementation: initial tests on a limited 750 m section within the yard, followed by performance metrics on speed, energy use, reliability, and integration before broader deployment. Results from this pilot are expected to influence decisions on port rail automation nationwide. This initiative positions India at the forefront of port logistics innovation within Asia. Similar systems have been deployed or tested in Europe, but this marks India's first on‑site demonstration combining magnetic propulsion and autonomy in a live port. Industry observers see potential for replication at other major ports, boosting capacity and reducing carbon footprints across maritime‑logistics hubs. Adoption of MagRail could revolutionise short‑haul freight by enabling fast, consistent and emissions‑free movement of containers between berths, storage yards, and hinterland connections. For DP World and the port authority, a successful trial could translate into scalable technology upgrades and competitive advantages in trade facilitation.

Everyone was very excited and very proud," Tusk said in another post, which included a photo of him seated next to several children at the science centre.
