Breaking AI & Tech News Analyzed

The Digital Roundabout: Understanding Phone AddictionWake up, 100 messages from group chat overnight about something – what? another assassination attempt; a village destroyed in Lebanon; the football result in England; the weather in Iran being manipulated; the pesticides causing lung and bowel cancer, so everyone who eats salads is now at risk of cancer; meditate for 20 minutes, then fire up x.com, a place I thought I'd never want to revisit, with its carnival barkers and supplement salesman, and have you seen the Lego thing calling Trump a paedo?, you gotta see the Lego thing, and this is before my first coffee, yet x.com is the coffee and the tea, whatever Elon has done to the For You algorithm is evil genius, it's like the global collective id, nasty and funny and addictive and compelling – like gawking at a car crash, like soaking in a hot bubble bath of anger, and memes, and geopolitical dramas, and Trump, Trump, Trump – soaking in Trump, and then, For Me (just as Elon promised).So begins the circuit around my phone, that goes all day and night, around the tiny screen with its icons (when a born-again Christian once told me he had favourite icons, for a long time I thought he meant apps, not pictures of the Virgin Mary). I started to feel like I was in Canberra, on one of those enormous roundabouts, rotating between the icons – not Joseph, not Jesus, but X and WhatsApp and TikTok and even LinkedIn for Christ sakes – round and round from one app to the next, just checking, checking in case something is happening. I watched tiny videos and maybe, occasionally, got distracted by the novel I am meant to be writing, which is due on 31 July. But the novel is boring, just a static Word doc on a screen, it's not giving; it's taking hard work. So I spend six minutes with my novel, and then it's time to go back to my phone, to circle the roundabout visiting all my icons again, like a demented Stations of the Cross, because I can't focus, I just can't focus on work right now when there is so much good scrolling to do …Clearly, this had to stop or I would become deranged and my novel wouldn't get finished by 31 July.But what could break the hold of a phone that seemed more and more addictive every day?The Physical Solution: Brick and Locked DevicesThen, while listening to a Guardian podcast (on my phone) I came across an author talking about a device that locked her phone and gave her her time and attention span back.I had tried apps to lock my phone before, but somehow having them embedded in the phone itself was like placing a piece of fruit in a box of chocolates. Sure you go in there to retrieve the fruit, but you end up distracted by the chocolates. Before you know it, the chocolates have been eaten! The fruit, of course, remains untouched and rotting.I needed an external device to lock my phone. This author was talking about something called Brick ($59US; £54 or $120 AUD including postage), a small plastic puck that you place on your phone which locks its most appealing apps. Hard!The Brick and its cheaper rival Locked ($39USD; £32; $59AUD) use Near Field Communication (NFC) technology to block whatever apps you nominate. To unblock them, you have to physically return to the puck and tap it against your phone. You can set a timer – I set it for one or two hour blocks when I want to focus on my novel – and if you try to unBrick beforehand, it asks you if you want to have a life, or if you want your phone back. That prompt is enough to make me affirm that, yes, I want a life.The Economics of Digital AttentionWhat Brick understands, and what every app-based screen time limit fails to grasp, is that the problem is not information or intention. I already knew I was using my phone too much. The problem is friction, or rather the total absence of it. Digital guardrails collapse the moment you need them most: one tap and you're back on Instagram. Brick makes that tap a physical hurdle.Using the Brick at night has been transformative. The hours I was losing in the roundabout, I now spend reading, thinking and occasionally just sitting in silence.The novel is moving again and I can focus in longer and longer increments.The algorithm doesn't get me after 8pm any more, and it turns out the algorithm, deprived of its evening session, has less purchase on me during the day too.The Psychology of Digital BoundariesBrick hasn't cured my addiction, but it has restored the thing addiction most destroys, which is the moment of pause between impulse and action.These physical devices represent a growing recognition that our relationship with technology requires more than just self-control – it needs environmental design and intentional friction to counteract the sophisticated algorithms designed to capture our attention.As digital products become increasingly sophisticated at capturing and holding our attention, the market for tools that help us reclaim our time and focus is likely to expand beyond simple app blockers to more comprehensive systems of digital wellbeing.The Future of Digital WellbeingLooking ahead, we can expect to see more innovative solutions that address the fundamental design principles of digital products. The success of devices like Brick suggests that consumers are becoming more aware of how their attention is being monetized and are seeking ways to regain control.As awareness of digital addiction grows, we may see regulatory interventions that require technology companies to build more ethical design principles into their products, potentially creating a market for both wellbeing tools and more responsibly designed digital experiences.Ultimately, the journey toward healthier digital habits will likely involve a combination of personal discipline, technological solutions, and systemic changes in how digital products are designed and monetized.

Scientists at London's Institute of Cancer Research and the RCSI University of Medicine and Health Sciences in Dublin have announced a new AI-driven approach to identify how patients with advanced bowel cancer will respond to bevacizumab, a drug recently introduced by the NHS. The method uses PhenMap, an AI tool that integrates complex data on the genetic makeup of tumors, allowing researchers to track patterns of how different patients react to the drug. This development aims to spare potentially thousands of patients from being given drugs that would be ineffective in fighting their cancers. In the UK alone, nearly 10,000 cases of advanced bowel cancer are identified every year, with young adults seeing a particular rise in diagnoses. Bowel cancer has the second-highest mortality rate of any cancer, behind only lung cancer. While survival rates can be as high as 98% when caught early, the five-year survival rate for advanced bowel cancer can be as low as 10%. The study tracked 117 European bowel cancer patients who had been treated with chemotherapy and bevacizumab. Researchers identified a group of patients who all had the same gene mutation and were at a high risk of having negative reactions. The scientists behind the tests now hope to expand the number of patient samples and see if the results can be used in treatments for other types of cancer. Anguraj Sadanandam, a professor in stratification and precision medicine at the ICR, said: “Once bowel cancer spreads to other parts of the body, there are very few treatment options available for patients. It is therefore positive that patients can now access the targeted drug bevacizumab on the NHS. However, we know that the majority of patients won’t benefit from the drug, meaning thousands of people in England could be facing unpleasant side effects unnecessarily.” Sadanandam added that while the findings were encouraging, the tool would need to be tested on a larger cohort to be validated. “In future, I hope this approach will lead to a test that can be used by clinicians, to ensure patients receive personalised care that has the highest chance of working against their cancer.”
