The Metropolitan Transportation Authority (MTA) in New York City has partnered with Google Public Sector on a pilot program designed to detect track defects before they cause significant disruptions. Using Google Pixel smartphones retrofitted onto subway cars, the system captured millions of sensor readings, GPS locations, and hours of audio to identify potential problems. The project aimed to improve the efficiency of the MTA’s response to track issues, potentially saving time and money while reducing delays for passengers.
The AI-powered program, called TrackInspect, analyses the sounds and vibrations from the subway to pinpoint areas that could signal defects, such as loose rails or worn joints. Data collected during the pilot, which ran from September 2024 to January 2025, showed that the AI system successfully identified 92% of defect locations found by human inspectors. The system was trained using feedback from MTA inspectors, helping refine its ability to predict track issues.
While the pilot was considered a success, the future of the program remains uncertain due to financial concerns at the MTA. Despite this, the success of the project has sparked interest from other transit systems looking to adopt similar AI-driven technologies to improve infrastructure maintenance and reduce delays. The MTA is now exploring other technological partnerships to enhance its track monitoring and maintenance efforts.

Nagasaki University in southwestern Japan, in collaboration with a local systems development company, has unveiled a new AI program aimed at enhancing medical student training.
The innovative program allows students to practice interviews with virtual patients on a screen, addressing the growing difficulty of securing simulated patients for training, especially in regional areas facing population declines.
In a demonstration earlier this month, an AI-powered virtual patient exhibited symptoms such as fever and cough, responding appropriately to questions from a medical student.
Scheduled for introduction by March 2026, the technology will allow students to interact with virtual patients of different ages, genders, and symptoms, enhancing their learning experience.
The university plans to enhance the program with scoring and feedback functions to make the training more efficient and improve the quality of learning.
Shinya Kawashiri, an associate professor at the university’s School of Medicine, expressed hope that the system would lead to more effective study methods.
Toru Kobayashi, a professor at the university’s School of Information and Data Sciences, highlighted the program as a groundbreaking initiative in Japan’s medical education landscape.

NHS is investigating allegations that a software flaw at private medical services company Medefer left patient data vulnerable to hacking.
The flaw, discovered in November, affected Medefer’s internal patient record system in the UK, which handles 1,500 NHS referrals monthly.
A software engineer who found the issue believes the vulnerability may have existed for six years, but Medefer denies this claim, stating no data has been compromised.
The engineer discovered that unprotected application programming interfaces (APIs) could have allowed outsiders to access sensitive patient information.
While Medefer has insisted that there is no evidence of any breach, they have commissioned an external security agency to review their systems. The agency confirmed that no breach was found, and the company asserts that the flaw was fixed within 48 hours of being discovered.
Cybersecurity experts have raised concerns about the potential risks posed by the flaw, emphasising that a proper investigation should have been conducted immediately.
Medefer reported the issue to the Information Commissioner’s Office (ICO) and the Care Quality Commission (CQC), both of which found no further action necessary. However, experts suggest that a more thorough response could have been beneficial given the sensitive nature of the data involved.

Taco Bell is ramping up its use of AI as part of a broader $1 billion investment by parent company Yum Brands in digital and technology.
At a recent investor event in New York, executives showcased the company’s ‘Byte by Yum’ AI tools, which aim to improve labour management and inventory tracking. Taco Bell’s Chief Digital and Technology Officer, Dane Mathews, said AI is already being used to streamline operations without reducing labour costs.
Around 500 Taco Bell locations in the United States now use AI-driven voice technology to handle drive-through orders, a significant increase from 100 locations in mid-2024.
During the investor event, executives presented a video skit demonstrating how AI could assist managers by suggesting staffing adjustments and optimising inventory. Analysts found the presentation both innovative and slightly unsettling, with Yum suggesting AI would help free up employees for other tasks rather than replace them.
Fast food chains are increasingly adopting AI to modernise operations, with companies like McDonald’s and Chipotle also investing in automation and digital tools. While Yum’s AI technology is currently used in nearly 25,000 of its 61,000 global restaurants, executives acknowledged there is still a long road ahead.
Analysts believe Yum may eventually commercialise its AI software beyond its own restaurant network. Taco Bell’s AI-driven strategy comes as the chain projects an 8% rise in same-store sales for the current quarter.

The US Federal Communications Commission (FCC) is set to vote next month on exploring alternatives to GPS due to growing national security concerns.
FCC Chair Brendan Carr warned that relying on a single system for navigation and timing leaves the United States vulnerable to disruptions. Reports of increased GPS interference, particularly spoofing attacks since 2023, have raised fears of accidents if aircraft are misdirected.
Concerns over GPS security have been discussed for years, with President Donald Trump and bipartisan lawmakers calling for action.
The FCC’s March 27 vote will launch an inquiry into alternative Positioning, Navigation, and Timing (PNT) systems that could complement or replace GPS. The aim is to encourage innovation in navigation technology and strengthen resilience against disruptions.
GPS plays a crucial role in aviation, replacing traditional ground-based navigation systems. However, its reliance on satellite signals makes it susceptible to interference.
The Federal Aviation Administration is already working on global authentication measures to counter spoofing threats and improve the security of satellite-based navigation.
