New AI device brings early skin cancer diagnosis to remote communities

A Scottish research team has developed a pioneering AI-powered tool that could transform how skin cancer is diagnosed in some of the world’s most isolated regions.

The device, created by PhD student Tess Watt at Heriot-Watt University, enables rapid diagnosis without needing internet access or direct contact with a dermatologist.

Patients use a compact camera connected to a Raspberry Pi computer to photograph suspicious skin lesions.

The system then compares the image against thousands of preloaded examples using advanced image recognition and delivers a diagnosis in real time. These results are then shared with local GP services, allowing treatment to begin without delay.

The self-contained diagnostic system is among the first designed specifically for remote medical use. Watt said that home-based healthcare is vital, especially with growing delays in GP appointments.

The device, currently 85 per cent accurate, is expected to improve further with access to more image datasets and machine learning enhancements.

The team plans to trial the tool in real-world settings after securing NHS ethical approval. The initial rollout is aimed at rural Scottish communities, but the technology could benefit global populations with poor access to dermatological care.

Heriot-Watt researchers also believe the device will aid patients who are infirm or housebound, making early diagnosis more accessible than ever.

Perplexity CEO predicts that AI browser could soon replace recruiters and assistants

Perplexity AI CEO Aravind Srinivas believes that the company’s new AI-powered browser, Comet, could soon replace two key white-collar roles in most offices: recruiters and executive assistants.

Speaking on The Verge podcast, Srinivas explained that with the integration of more advanced reasoning models like GPT-5 or Claude 4.5, Comet will be able to handle tasks traditionally assigned to these positions.

He also described how a recruiter’s week-long workload could be reduced to a single AI prompt.

From sourcing candidates to scheduling interviews, tracking responses in Google Sheets, syncing calendars, and even briefing users ahead of meetings, Comet is built to manage the entire process—often without any follow-up input.

The tool remains in an invite-only phase and is currently available to premium users.

Srinivas also framed Comet as the early foundation of a broader AI operating system for knowledge workers, enabling users to issue natural language commands for complex tasks.

He emphasised the importance of adopting AI early, warning that those who fail to keep pace with the technology’s rapid growth—where breakthroughs arrive every few months—risk being left behind in the job market.

In a separate discussion, he urged younger generations to reduce time spent scrolling on Instagram and instead focus on mastering AI tools. According to him, the shift is inevitable, and those who embrace it now will hold a long-term professional advantage.

DuckDuckGo adds new tool to block AI-generated images from search results

Privacy-focused search engine DuckDuckGo has launched a new feature that allows users to filter out AI-generated images from search results.

Although the company admits the tool is not perfect and may miss some content, it claims it will significantly reduce the number of synthetic images users encounter.

The new filter uses open-source blocklists, including a more aggressive ‘nuclear’ option, sourced from tools like uBlock Origin and uBlacklist.

Users can access the setting via the Images tab after performing a search or use a dedicated link — noai.duckduckgo.com — which keeps the filter always on and also disables AI summaries and the browser’s chatbot.

The update responds to growing frustration among internet users. Platforms like X and Reddit have seen complaints about AI content flooding search results.

In one example, users searching for ‘baby peacock’ reported seeing just as many or more AI images than real ones, making it harder to distinguish between fake and authentic content.

DuckDuckGo isn’t alone in trying to tackle unwanted AI material. In 2024, Hiya launched a Chrome extension aimed at spotting deepfake audio across major platforms.

Microsoft’s Bing has also partnered with groups like StopNCII to remove explicit synthetic media from its results, showing that the fight against AI content saturation is becoming a broader industry trend.

Irish hospital turns to AI for appointment management

Beaumont Hospital in Dublin plans to deploy AI to predict patient no-shows and late cancellations, aiming to reduce wasted resources.

Instead of relying solely on reminders, the hospital will pilot AI software costing up to €110,000, using patient data to forecast missed appointments. Currently, no-shows account for 15.5% of its outpatient slots.

The system will integrate with Beaumont’s existing two-way text messaging service. Rather than sending uniform reminders, the AI model will tailor messages based on the likelihood of attendance while providing hospital staff with real-time insights to better manage clinic schedules.

The pilot is expected to begin in late 2025 or early 2026, potentially expanding into a full €1.2 million contract.

The move forms part of Beaumont Hospital’s strategic plan through 2030 to reduce outpatient non-attendance. It follows the broader adoption of AI in Irish healthcare, including Mater Hospital’s recent launch of an AI and Digital Health centre designed to tackle clinical challenges using new technologies.

Instead of viewing AI as a future option, Irish hospitals now increasingly treat it as an immediate solution to operational inefficiencies, hoping it will transform healthcare delivery and improve patient service.

Library cuts across Massachusetts deepen digital divide

Massachusetts libraries face sweeping service reductions as federal funding cuts threaten critical educational and digital access programmes. Local and major libraries are bracing for the loss of key resources including summer reading initiatives, online research tools, and English language classes.

The Massachusetts Board of Library Commissioners (MBLC) said it has already lost access to 30 of 34 databases it once offered. Resources such as newspaper archives, literacy support for the blind and incarcerated, and citizenship classes have also been cancelled due to a $3.6 million shortfall.

Communities unable to replace federal grants with local funds will be disproportionately affected. With over 800 library applications for mobile internet hot spots now frozen, officials warn that students and jobseekers may lose vital lifelines to online learning, healthcare and employment.

The cuts are part of broader efforts by the Trump administration to shrink federal institutions, targeting what it deems anti-American programming. Legislators and library leaders say the result will widen the digital divide and undercut libraries’ role as essential pillars of equitable access

Hackers hide malware using DNS TXT records

Hackers are increasingly exploiting DNS records to deliver malware undetected, according to new research from DomainTools.

Instead of relying on typical delivery methods such as emails or downloads, attackers now hide malicious code within DNS TXT records, part of the Domain Name System, often overlooked by security systems.

The method involves converting malware into hexadecimal code, splitting it into small segments, and storing each chunk in the TXT record of subdomains under domains like whitetreecollective.com.

Once attackers gain limited access to a network, they retrieve these chunks via ordinary-looking DNS queries, reassembling them into functioning malware without triggering antivirus or firewall alerts.

The rising use of encrypted DNS protocols like DNS-over-HTTPS and DNS-over-TLS makes detecting such queries harder, especially without in-house DNS resolvers equipped for deep inspection.

Researchers also noted that attackers are using DNS TXT records for malware and embedding harmful text designed to manipulate AI systems through prompt injection.

Ian Campbell of DomainTools warns that even organisations with strong security measures struggle to detect such DNS-based threats due to the hidden nature of the traffic.

Instead of focusing solely on traditional defences, organisations are advised to monitor DNS traffic closely, log and inspect queries through internal resolvers, and restrict DNS access to trusted sources. Educating teams on these emerging threats remains essential for maintaining robust cybersecurity.

OpenAI releases ChatGPT agent with task automation tools

OpenAI has introduced a general-purpose AI agent within ChatGPT, aiming to move beyond answering questions by completing various computer-based tasks.

Known as ChatGPT agent, the tool allows users to navigate calendars, generate editable presentations, and write code simply by using natural language prompts.

Rather than acting as a standalone product, ChatGPT agent integrates capabilities from OpenAI’s earlier tools, combining website navigation and in-depth research features.

Rolling out to Pro, Plus, and Team subscribers, the ChatGPT agent also connects with external apps like Gmail and GitHub. Instead of being limited to basic queries, it can access a terminal and use APIs, enabling tasks such as analysing competitors or planning shopping lists.

OpenAI claims its underlying model delivers state-of-the-art results, scoring significantly higher than previous versions on academic and maths benchmarks.

While positioning ChatGPT as its most capable AI tool yet, OpenAI has implemented several new safety measures due to the agent’s potential risks. The company acknowledges its model could amplify harm in sensitive areas like biological and chemical threats.

To mitigate such dangers, OpenAI monitors prompts in real time and turns off ChatGPT’s memory feature within the agent to avoid data leaks through malicious attacks.

Despite these precautions, questions remain over whether the ChatGPT agent will consistently perform complex tasks in the real world. Earlier agent technologies from various companies have often failed to meet expectations.

OpenAI, however, insists its new release represents a more robust step towards fulfilling the vision of practical AI agents.

AI brings new life to martial arts cinema legends

China is embarking on a major digital restoration project to preserve its rich martial arts film heritage. Announced at the Shanghai International Film Festival, the government-backed initiative aims to restore 100 classic kung fu movies using AI.

Unlike Hollywood’s trend of digitally recreating actors, this effort focuses on enhancing image and sound quality while preserving the original storytelling and aesthetics. Films like Bruce Lee’s Fist of Fury, Jackie Chan’s Police Story, and Jet Li’s Once Upon a Time in China will receive the high-definition makeover.

The project, supported by the China Film Foundation, is being framed to safeguard cultural treasures for future generations. Officials emphasise that AI will serve only as a preservation tool, not altering the essence of these iconic works.

However, the initiative has sparked debate: some critics fear that overreliance on technology could dilute the human touch in cinema, while supporters believe this will help introduce these classics to younger global audiences who may otherwise overlook them.

In parallel, China is experimenting with a more radical approach through A Better Tomorrow: Cyber Border, a fully AI-animated reboot that reimagines a beloved story rather than simply restoring it. That contrast highlights the country’s growing ambition to blend tradition with cutting-edge technology in the entertainment industry. Whether seen as a bold step toward the future or a controversial new chapter, the legendary kung fu films of the past are poised to shine again in stunning clarity.

Most US teens use AI companion bots despite risks

A new national survey shows that roughly 72% of American teenagers, aged 13 to 17, have tried AI companion apps such as Replika, Character.AI, and Nomi, with over half interacting with them regularly.

Although some teens report benefits like practising conversation skills or emotional self-expression, significant safety concerns have emerged.

Around 34% have been left uncomfortable by the bot’s behaviour, and one-third have turned to AI for advice on serious personal issues. Worryingly, nearly a quarter of users disclosed their real names or locations in chats.

Despite frequent use, most teens still prefer real friendships—two-thirds say AI interactions are less satisfying, and 80% maintain stronger ties to human friends.

Experts warn that teens are especially vulnerable to emotional dependency, manipulative responses, and data privacy violations through these apps.

Youth advocates call for mandatory age verification, better content moderation, and expanded AI literacy education, arguing that minors should not use companionship bots until more regulations are in place and platforms become truly safe for young users.
