A new study in Robot Learning has introduced a robotic system that combines machine learning with decision-making to analyse water samples. The approach enables robots to detect, classify, and distinguish drinking water on Earth and potentially other planets.
Researchers used a hybrid method that merged the TOPSIS decision-making technique with a Random Forest Classifier trained on the Water Quality and Potability Dataset from Kaggle. By applying data balancing techniques, classification accuracy rose from 69% to 73%.
The robotic prototype includes thrusters, motors, solar power, sensors, and a robotic arm for sample collection. Water samples are tested in real time, with the onboard model classifying them as drinkable.
The system has the potential for rapid crisis response, sustainable water management, and planetary exploration, although challenges remain regarding sensor accuracy, data noise, and scalability. Researchers emphasise that further testing is necessary before real-world deployment.

Coinbase positions stablecoins at the heart of AI-powered apps, bots, and machines. Over a sweltering August weekend in Brooklyn, around 100 developers from across the globe built tools enabling software to send and receive payments using these digital dollars.
Projects included instant-pay publishing platforms, chatbots charging small fees, and group marketplaces operating independently of traditional banks.
The company is promoting x402, an open-source protocol named after the ‘402 Payment Required’ internet error, designed to let apps and software settle payments instantly using stablecoins.
Developers were encouraged to integrate x402 into their projects, offering real-time microtransactions without relying on PayPal, Visa, or banks. Coinbase hopes the protocol becomes the go-to toolkit for app builders, similar to how Amazon Web Services underpins the internet.
Competition intensifies as Stripe, PayPal, Visa, and Mastercard explore stablecoin infrastructure. Recent US legislation regulating stablecoins provides legal clarity, encouraging developers to innovate confidently.
Despite traditional payment systems and slow-changing consumer habits, Coinbase’s hackathon showcased growing ambitions to develop AI financial infrastructure. Stablecoins are being positioned not just as digital assets, but as functional tools for the next generation of software payments.

OpenAI’s rollout of GPT-5 has faced criticism from users attached to older models, who say the new version lacks the character of its predecessors.
GPT-5 was designed as an all-in-one model, featuring a lightweight version for rapid responses and a reasoning version for complex tasks. A routing system determines which option to use, although users can manually select from several alternatives.
Modes include Auto, Fast, Thinking, Thinking mini, and Pro, with the last available to Pro subscribers for $200 monthly. Standard paid users can still access GPT-4o, GPT-4.1, 4o-mini, and even 3o through additional settings.
Chief executive Sam Altman has said the long-term goal is to give users more control over ChatGPT’s personality, making customisation a solution to concerns about style. He promised ample notice before permanently retiring older models.

A new MIT study has found that 95% of corporate AI projects fail to deliver returns, mainly due to difficulties integrating them with existing workflows.
The report, ‘The GenAI Divide: State of AI in Business 2025’, examined 300 deployments and interviewed 350 employees. Only 5% of projects generated value, typically when focused on solving a single, clearly defined problem.
Executives often blamed model performance, but researchers pointed to a workforce ‘learning gap’ as the bigger barrier. Many projects faltered because staff were unprepared to adapt processes effectively.
More than half of GenAI budgets were allocated to sales and marketing, yet the most substantial returns came from automating back-office tasks, such as reducing agency costs and streamlining roles.
The study also found that tools purchased from specialised vendors were nearly twice as successful as in-house systems, with success rates of 67% compared to 33%.

Google Cloud has unveiled a suite of security enhancements at its Security Summit 2025, focusing on protecting AI innovations and empowering cybersecurity teams with AI-driven defence tools.
VP and GM Jon Ramsey highlighted the growing need for specialised safeguards as enterprises deploy AI agents across complex environments.
Central to the announcements is the concept of an ‘agentic security operations centre,’ where AI agents coordinate actions to achieve shared security objectives. It represents a shift from reactive security approaches to proactive, agent-supported strategies.
Google’s platform integrates automated discovery, threat detection, and response mechanisms to streamline security operations and cover gaps in existing infrastructures.
Key innovations include extended protections for AI agents through Model Armour, covering Agentspace prompts and responses to mitigate prompt injection attacks, jailbreaking, and data leakage.
The Alert Investigation agent, available in preview, automates enrichment and analysis of security events while offering actionable recommendations, reducing manual effort and accelerating response times.
Integrating Mandiant threat intelligence feeds and Gemini AI strengthens detection and incident response across agent environments.
Additional tools, such as SecOps Labs and native SOAR dashboards, provide organisations with early access to AI-powered threat detection experiments and comprehensive security visualisation capabilities.

The Commonwealth Bank of Australia has reversed plans to cut 45 customer service roles following union pressure over the use of AI in its call centres.
The Finance Sector Union argued that CBA was not transparent about call volumes, taking the case to the Workplace Relations Tribunal. Staff reported rising workloads despite claims that the bank’s voice bot reduced calls by 2,000 weekly.
CBA admitted its redundancy assessment was flawed, stating that it had not fully considered the business needs. Impacted employees are being offered the option to remain in their current roles, relocate within the firm, or depart.
The Bank of Australia apologised and pledged to review internal processes. Chief executive Matt Comyn has promoted AI adoption, including a new partnership with OpenAI, but the union called the reversal a ‘massive win’ for workers.
