Google claims Gemini uses less water and energy per text prompt

Google has published new estimates on the environmental footprint of Gemini, claiming a single text prompt uses about five drops of water and 0.24 watt-hours of electricity. The company says this equates to 0.03 grams of carbon dioxide emissions.

According to Google, efficiencies have reduced Gemini’s energy consumption and carbon footprint per text prompt by factors of 33 and 44 over the past year. Chief technologist Ben Gomes said the model now delivers higher-quality responses with a significantly lower footprint.

The company argued that these figures are significantly lower than those suggested in earlier research. However, Shaolei Ren, the author of one of the cited papers, said Google’s comparisons were misleading and incomplete.

Ren noted that Google compared its latest onsite-only water figures against his study’s highest total figures, creating the impression that Gemini was far more efficient. He also said Google omitted indirect water use, such as electricity-related consumption, from its estimates.

South Korea unveils five-year AI blueprint for ‘super-innovation economy’

South Korea’s new administration has unveiled a five-year economic plan to build what it calls a ‘super-innovation economy’ by integrating AI across all sectors of society.

The strategy, led by President Lee Jae-myung, commits 100 trillion won (approximately US$71.5 billion) to position the country among the world’s top three AI powerhouses. Private firms will drive development, with government support for nationwide adoption.

Plans include a sovereign Korean-language AI model, humanoid robots for logistics and industry, and commercialising autonomous vehicles by 2027. Unmanned ships are targeted for completion by 2030, alongside widespread use of drones in firefighting and aviation.

AI will also be introduced into drug approvals, smart factories, welfare services, and tax administration, with AI-based tax consultations expected by 2026. Education initiatives and a national AI training data cluster will nurture talent and accelerate innovation.

Five domestic firms, including Naver Cloud, SK Telecom, and LG AI Research, will receive state support to build homegrown AI foundation models. Industry reports currently rank South Korea between sixth and 10th in global AI competitiveness.

US and EU strike new trade agreement

The United States and the European Union have concluded a trade agreement that lowers tariffs and removes barriers for industrial, agricultural, and digital sectors. The pact formalises July’s commitments and aims to strengthen transatlantic economic ties.

Under the terms, Washington will reduce tariffs on European automobiles from 27.5% to 15% once Brussels lowers restrictions on US goods. Europe also pledged to buy $750 billion worth of American energy and to lift tariffs on all US industrial products.

Agricultural concessions include greater access for dairy, pork, nuts, and seafood, with an extension of the 2020 lobster deal.

The agreement extends beyond trade in goods. Brussels committed not to introduce digital network fees opposed by Washington and promised adjustments to sustainability regulations that could disadvantage non-EU firms.

Both sides emphasised the deal as the first step towards deeper cooperation in trade and investment.

Ransomware attack at DaVita exposes data of 2.7 million patients in the US

A ransomware attack against dialysis provider DaVita has exposed the personal data of 2.7 million people, according to a notice on the US health department’s website.

The company first disclosed the cyber incident in April, saying it had taken steps to restore operations but could not predict the scale of disruption.

DaVita confirmed that hackers gained unauthorised access to its laboratory database, which contained sensitive information belonging to some current and former patients. The firm said it is now contacting those affected and offering free credit monitoring to help protect against identity theft.

Despite the intrusion, DaVita maintained uninterrupted dialysis services across its network of nearly 3,000 outpatient clinics and home treatment programmes. The company described the cyberattack as a temporary disruption but stressed that patient care was never compromised.

Financial disclosures show the incident led to around $13.5 million in charges during the second quarter of 2025. Most of the costs were linked to system restoration and third-party support, with $1 million attributed to higher patient care expenses.

Meta strikes $10 billion cloud deal with Google

Meta has signed a cloud computing deal with Google worth more than $10 billion, marking one of the most significant agreements in the industry.

The six-year partnership will see Meta use Google Cloud’s servers, storage, networking and other services to power its massive AI projects.

The deal comes as Meta accelerates its AI infrastructure spending, with CEO Mark Zuckerberg pledging hundreds of billions of dollars for new data centres.

Last month, Meta raised its capital expenditure forecast to $72 billion and disclosed plans to offload $2 billion in data centre assets to outside partners.

The partnership highlights a growing trend of rival technology giants collaborating on AI infrastructure. Just weeks earlier, OpenAI struck a similar deal to use Google Cloud services despite being a competitor in the AI field.

These agreements have boosted Google Cloud’s performance, which saw a 32% jump in second-quarter revenue in July, surpassing market expectations.

Google pushes agentic AI worldwide with AI Mode rollout

Google has expanded its AI Mode service to 180 additional countries, extending advanced agentic capabilities to a global audience.

Previously available only in markets such as the US, UK and India, the service allows users to search for information and carry out tasks on their behalf. The update reflects Google’s ambition to move from simple answers to action-oriented assistance.

A key rollout feature is the restaurant booking tool for AI Ultra subscribers. Using natural language requests such as ”find a romantic Italian spot for two tonight,” the system can check availability, offer personalised suggestions and confirm reservations directly within search.

The feature relies on real-time data from partners like OpenTable and highlights how Google’s AI can execute tasks instead of simply presenting options.

Further tools are expected soon, including ticketing for events and appointment scheduling. These are powered by the Gemini models, which tailor recommendations based on user behaviour and allow group planning through shared responses.

While the services could reduce reliance on third-party apps in sectors such as travel and hospitality, they also raise concerns over data privacy, inclusivity and cultural differences in an English-only rollout.

The global expansion strengthens Google’s position against rivals like Microsoft and OpenAI, who are also pushing forward in agentic AI. The company sees subscription upgrades to AI Ultra as a way to offset slower advertising growth, while early reports suggest increased user engagement.

However, the long-term impact will depend on balancing innovation with ethical safeguards as Google works to deliver more multilingual and accessible features.

Energy independence enables new models for data centre construction

Many data centre developers face delays due to grid constraints or unreliable utilities. To circumvent these challenges, they are embracing alternative power setups.

Popular options include solar arrays paired with battery storage, microgrid deployments, mobile gas generators, and even hydrogen fuel cells. These systems offer more control, robust uptime and faster deployment than waiting for utility upgrades.

Such energy independence also increases site flexibility. Operators can choose locations without worrying about grid strengthening or local permitting delays, enhancing both scalability and disaster resilience.

As demand for cloud and AI capacity grows, hybrid energy architectures are proving vital. They ensure continuity and avoid overtaxed grid infrastructure.

Microsoft limits certain companies’ access to the SharePoint early warning system

Microsoft has limited certain Chinese companies’ access to its early warning system for cybersecurity vulnerabilities following suspicions about their involvement in recent SharePoint hacking attempts.

The decision restricts the sharing of proof-of-concept code, which mimics genuine malicious software. While valuable for cybersecurity professionals strengthening their systems, the code can also be misused by hackers.

The restrictions follow Microsoft’s observation of exploitation attempts targeting SharePoint servers in July. Concerns arose that a member of the Microsoft Active Protections Program may have repurposed early warnings for offensive activity.

Microsoft maintains that it regularly reviews participants and suspends those violating contracts, including prohibitions on participating in cyber attacks.

Beijing has denied involvement in the hacking, while Microsoft has refrained from disclosing which companies were affected or details of the ongoing investigation.

Analysts note that balancing collaboration with international security partners and preventing information misuse remains a key challenge for global cybersecurity programmes.

New robotic system uses AI to analyse water quality

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.

Fed urges banks to embrace blockchain innovation

Federal Reserve Vice Chair for Supervision Michelle Bowman has warned that banks must embrace blockchain technology or risk fading into irrelevance. At the Wyoming Blockchain Symposium on 19 August, she urged banks and regulators to drop caution and embrace innovation.

Bowman highlighted tokenisation as one of the most immediate applications, enabling assets to be transferred digitally without intermediaries or physical movement.

She explained that tokenised systems could cut operational delays, reduce risks, and expand access across large and smaller banks. Regulatory alignment, she added, could accelerate tokenisation from pilots to mainstream adoption.

Fraud prevention was also a key point of her remarks. Bowman said financial institutions face growing threats from scams and identity theft, but argued blockchain could help reduce fraud.

She called for regulators to ensure frameworks support adoption rather than hinder it, framing the technology as a chance for collaboration between the industry and the Fed.
