The Lead Swiss startup VunaNexus has developed a technology to recycle urine into a natural fertiliser called Aurin, which is certified for use on all plants by Swiss and French authorities. The Urine Recycling Process The process involves collecting urine from special toilets, treating it, and concentrating its nutrients into a liquid fertiliser. The urine is collected from special toilets that separate the liquid from water, and then it is treated in a small plant in the basement of the building. The treatment process removes micropollutants and concentrates the valuable nutrients such as nitrogen and phosphorus. The Data Analysis The fertiliser, Aurin, is sold to farmers, used in gardens and on house plants, and is being tested by city authorities in Paris, Lausanne, and Zurich. VunaNexus says that if all the urine of people in Europe were recycled, it could cover around 30% of the nitrogen need. The Impact Analysis The fertiliser market has become increasingly vulnerable due to the conflict in Ukraine, which has sent fertiliser prices soaring. The UN has said that 45 million people are at risk of acute hunger because of the conflict in the Middle East as fertiliser prices soar and the supply shock threatens food security in some of the world's poorest countries. The Prediction VunaNexus needs to scale its fertiliser production and get paid for the wastewater treatment service it provides to become competitive on the agricultural market. The company is working on finding ways to deliver improved urban sanitation that can produce fertilisers, and its technology is being rolled out across a newly developed eco neighbourhood in Paris, which will be the biggest project of its kind in Europe.

The LeadRoman Mars, the creator of the popular podcast 99% Invisible, is launching a new podcast called A History of the United States in 100 Objects, a sequel to the series A History of the World in 100 Objects that aired on Radio 4 in 2010. The Event DetailsMars's new series, co-produced by BBC Studios, SiriusXM, and 99% Invisible, comprises 100 episodes airing across two years, each highlighting objects and designs that tell the broader story of the United States. The podcast aims to explore American history through unusual items, such as the screw thread, the Bundy Clock, a gold coin recovered from the SS Central America, and the Billy Possum. The Data AnalysisMars has been researching the series for months, reading multiple books at once and listening to audiobooks at double speed while walking his dog. He believes that the experience has been akin to "putting myself through an American Studies major". The Impact AnalysisThe podcast is timed to coincide with the 250th anniversary of the US Declaration of Independence. Mars hopes to approach American history from a different perspective, using design as a lens to look at certain objects and ask what they say about America. The PredictionMars believes that his broadcasting career would not have taken off without the rise of podcasting. He notes that his voice is not a good fit for traditional radio, which prefers a clear and clipped tone. However, he has found his voice and become very relaxed behind the microphone, and he prefers to be the voice in listeners' heads rather than on video.

The Departure of a Key Tech Voice in GovernmentFormer tech executive and venture capitalist Sriram Krishnan is set to leave his role as senior policy advisor on artificial intelligence at the White House at the end of June. In a post on X, Krishnan expressed gratitude for the opportunity to serve under President Donald Trump, stating, "Without his leadership, we would not be leading in the AI race."The Tech Executive's Government JourneyKrishnan joined the Trump administration as part of a trend of tech industry figures taking roles in the second Trump administration. Prior to his government position, Krishnan led product teams at major tech companies including Microsoft, Twitter, Yahoo, Facebook, and Snap. He was most recently a partner at Andreessen Horowitz, a venture firm whose founders threw their support behind Trump during the 2024 election.AI Policy Accomplishments During TenureDuring his time at the White House, Krishnan highlighted several key accomplishments, most notably the administration's AI Action Plan. This plan prioritized data center construction over regulation and safety measures. Under his influence, President Trump signed several executive orders related to artificial intelligence, including one that seeks to challenge state-level AI regulations and another focused on oversight that was delayed and narrowed after industry pushback.Collaboration with David SacksIn his farewell message, Krishnan specifically mentioned David Sacks, the investor and podcaster who stepped down as AI and crypto czar earlier this year and became co-chair of the President's Council of Advisors on Science and Technology. Krishnan noted that Sacks "continuing advocacy for America winning on AI has been and continues to be crucial" during his time in government.Future Plans in AI Policy InfluenceAccording to The Washington Post, Krishnan is planning to start an outside institution that will still allow him to play a role in influencing Trump's AI policy. In his post, he indicated his next steps would involve "building institutions" that tackle big challenges for "America and its allies." Specifically, he mentioned issues such as energy, data centers, and creating "a clear path for Americans to experience the benefits of AI."

The Bridge Between Art and ScienceWhy do we find things beautiful? More precisely, why do some paintings of coloured dots in rippling patterns inspire in me something like revelation? The idea that beauty is the feeling you get when encountering truth is unfashionable in the arts, but lingers in the sciences. The physicist Paul Dirac once proposed that it is more important that a formula is beautiful than that it can be proven: when a perfectly beautiful theory produces results that cannot be real, he argued, then we should not discard the theory but reconsider what is real.Since the 1970s, Terry Winters has been rebuilding that bridge between art and science. Taking inspiration from disciplines including botany – his early paintings, particularly, evoke sprouting pods and tangled roots – engineering, computer modelling and cybernetics, his paintings might be understood as diagrammatic approximations of the patterns that govern everything from the division of cells to the constellation of stars. If every era has to renew its standards of beauty to reflect new understandings of how the world is constructed, then Winters comes as close to providing that model as any living painter.Mathematical Patterns in Visual ArtThese eight new works take their titles from the language of geometry and mathematics: Area, Array, Field, Locus, Point, Scope, Sequence and Set. Each is composed of overlapping patterns that pull each other out of shape according to invisible laws of attraction and repulsion. Field is indicative: on a sooty pink ground, a dense grid of dusty blue cells bends inwards like a trampoline beneath a bowling ball, while an intersecting arrangement of larger circles swells outwards. The disorienting effect of this push-pull is exaggerated by an optical illusion, created by ragged phosphorescent orange haloes around the blue circles, that makes them appear to be craters sunk into the crust of paint. You have to walk up to the surface to be reassured that it is flat.Point shows a teeming landscape of cells bulging outwards at the centre, as if a scum of frogspawn had been skimmed off a pond and placed under a paperweight microscope. In Sequence, a storm of pink interference skims through a yellow circle split like a brain into hemispheres, while a nebulous weather system sweeps in from the right. In Scope, vaguely symbolic arrangements of freshwater blue and desert orange nodules move across the familiar circle-within-a-square geometry of Leonardo's Vitruvian Man. Where that famous demonstration of sacred geometries exudes stillness and calm, the systems that run through Winters' worlds are wild and strange. Here, as much importance is given to the subjective factors of perception and consciousness as the objective principles of logic and proportion.Optical Illusions and Sensory ExperienceAll of this should not distract from the pure sensory pleasure afforded by these pictures. In Locus, another optical illusion seems to lift the red edge of the painting off the canvas like a clumsy wooden frame, squeezing the pockmarked sphere at its centre so that it balloons outwards, threatening to burst. The same cadmium red, so sandy that the pigment seems barely to have been suspended in oil, turns carmine pockets into rock formations that climb off the surface of Set. These sleights of hand evoke the more secular movement of op art, in which patterns are manipulated to exploit the idiosyncrasies of human perception rather than to uncover deeper truths. Which begs the question: is this all just a conjuring trick?Rediscovering the Renaissance ApproachThere is something magical about these works. Even though Winters is generally credited with having extended the lineage of modernist American painting into the present, his practice is in this sense pre-modern. In its rejection of the idea that art should be separated from science, it resembles the Renaissance attitude according to which painting is no less a tool for understanding the world than mathematics, and magic is just the name for things we don't yet understand. His commitment to synthesising diverse spheres of knowledge, his alchemist's commitment to materials, and his sheer technical ability certainly mark him out in a scene recently overwhelmed by chancers and charlatans, bandwagoners and snake-oil salesmen. That his work is enjoying a revival might be taken as an encouraging sign.Beauty as a Path to TruthDirac, incidentally, was proved right. He formulated a theory that was so beautiful it couldn't possibly be wrong, even though it implied the existence of phenomena that everyone agreed must be impossible. He stood by it, and a few years later, someone else discovered anti-matter. Winters' paintings likewise offer a flash of those secret patterns that underpin the physical world, and which science has yet to illuminate. Which is to say, they're beautiful.Exhibition DetailsTerry Winters: Along the River is at Modern Art, London, until 11 July

The PlayStation Strategic ShiftPlayStation's future has looked a little uncertain these past few years. Although the PS5 has sold well and been very profitable, the brand is far from the runaway market leader it was in the PS2 days. Earlier this week, Game File dug into Sony's most recent earnings reports to illustrate how PlayStation has been selling fewer and fewer of its own flagship games since a peak during the pandemic. About 54.1m copies of games either developed or published by Sony were sold in the 2018 financial year; in 2025, it sold 32.1m.The State of Play Event OverviewSo what is Sony going to do in the next few years, as we enter a later stage of the PS5 lifecycle? Will it play safe, or diversify? Perhaps revive some older games for nostalgic millennials? Thanks to a State of Play live-stream last night, we now have some answers. Here's what's on the slate:Marvel's Wolverine: A Violent DepartureCalifornian developer Insomniac's next Marvel adaptation after the somewhat wholesome Spider-Man adventures is an exceptionally violent Wolverine game. Seriously, we see those claws go through about seven people in the first 30 seconds of the demo, before fellow mutant Jean Grey shows up and starts killing people with telekinesis instead. A motorbike chase follows, and a showdown atop a moving vehicle. Truly all the Hollywood-esque action a player could possibly want, if also rather more blood spatter than some of us can take. There was also less 18-rated Marvel action in the form of comic-book-style fighting game Marvel Tokon: Fighting Souls (coming 6 August).Horror Revival with Silent Hill: TownfallThis Silent Hill spin-off, from the Scottish developer Screen Burn, looks excellent. It's a horror game set in a misty town on the east coast of Scotland. Expect: many disgusting creatures that arise from the depths of its characters' worst imaginings. Many eerily abandoned little seaside homes. Many ominous shots of closed doors at the end of hallways. And much creepy radio static.Classic Franchises ReturnCapcom revives another of its classic PlayStation series in this Japanese-mythology action game, in which you slice up demons with a katana. (It will have to work hard to compete with the Nioh games and FromSoftware's Sekiro, which have filled this niche in the two decades Onimusha has been away.) The demo is available to try now.Although this was announced late last year, we've just got our first good look at it. It's a remake of the very first Tomb Raider, and they really mean it – it looks like a new Uncharted game. It's got all the classics: Egyptian tombs, jungle temples, T-Rexes, and Lara Croft looks badass in a modernised version of her classic outfit.Market Competition ContextSony has put out some great homegrown games since the PS5 was released in 2020, from Astro Bot to Ghost of Yōtei, but it has also had some expensive and very public failures and cancellations; PlayStation boss Jim Ryan, who retired in 2024, placed big bets on live-service games and only a few panned out (hello, Helldivers). Sony also seems to have rolled back on releasing its single-player PS5 games on PC after a polite interval of time, suggesting it wants to preserve what advantage and exclusivity it has.Meanwhile, its longtime console rival Xbox may have faded into the background as a sales competitor – the PS5 has outsold the Xbox Series S/X by approximately three to one – but it has become a strong publishing competitor, having bought up tens of development studios alongside Activision and Bethesda. Then there's Nintendo, whose exclusive games for the Switch and Switch 2 consoles have performed significantly better than Sony's over the last decade. (The top-selling Sony-developed PS4 game was Spider-Man, at 22.68m. The top-selling Nintendo-developed Switch game was Mario Kart 8 Deluxe at … 71m.)Strategic Implications for SonyThe State of Play event reveals Sony's strategic approach to the next phase of the PS5 lifecycle. By reviving classic franchises like Onimusha and Tomb Raider while investing in high-profile exclusives like Marvel's Wolverine and horror properties like Silent Hill, Sony appears to be balancing nostalgia with innovation. The company seems to be acknowledging its need to strengthen exclusive content while also diversifying its portfolio beyond live-service games that haven't always met expectations.Future Outlook for PlayStationWith releases spanning from late 2026 into 2027, Sony appears to be building a substantial pipeline of exclusive content designed to maintain PS5 momentum. The emphasis on both established franchises and new intellectual properties suggests a strategy to appeal to multiple segments of the gaming audience. As the console market matures and competition intensifies, Sony's ability to deliver compelling exclusive experiences will be crucial in maintaining its market position against Microsoft's expanded publishing arm and Nintendo's consistently strong first-party offerings.

The Future of Warfare: AI-Powered Drones Should the AI-powered drones of the future have a licence to kill? The question is becoming ever more pressing as governments and the defence industry acknowledge that drone systems will play an increasingly crucial role in future warfare. The Moral Dilemma of Autonomous Weapons With drones being deployed in huge numbers in the Ukraine war and AI being used to assist bombing missions in the Iran conflict, there is an expectation among some observers that weapons will have to operate with increased operational autonomy, which means they will need something approximating a moral framework. Expert Opinions on AI and Morality Last year Mustafa Suleyman, chief executive of Microsoft’s AI arm and a co-founder of the UK-based DeepMind, was unequivocal about the issue of machines making moral decisions. He said: “AIs cannot be people – or moral beings.” David Omand, the former head of the UK spy agency, GCHQ, believes AI can create a “moral” configuration for unmanned weapons. The UK armed forces minister, Al Carns, told the Financial Times recently there must be an option to “take the human out of the loop” in decision-making. The Challenges of Programming Morality Zee Talat, an academic specialising in machine learning at the University of Edinburgh’s school of informatics, argues that large language models – the technology that underpins modern generative AI systems such as chatbots – are fundamentally incapable of moral decision-making. “If you have a machine that’s probabilistic by nature it will veer towards the most likely answer in a situation. Do we think that morality follows probabilistic notions?” The Debate on Autonomous Weapons Governance Jessica Dorsey, an assistant professor of international law at Utrecht University in the Netherlands, raises concerns about determining whose morality the drone is following, given the United Nations is still trying to achieve a global consensus on autonomous weapons governance. “War is filled with so many variables and it is a given that things will go wrong. And when that happens at AI-like speed, it is difficult to unravel.” The Future of AI-Powered Drones Some experts argue that giving drones greater autonomy, and programming rules of engagement and morality into them, will be a necessity if other nation states continue to develop and deploy similar technology at pace. Nicholas Wright, a neuroscientist and author of Warhead, a book on the human brain and war, says: “For any military to compete effectively against other high-end militaries it is going to need a large amount of systems that will be required to take decisions on their own.” Olaf Hichwa, the co-founder of Neros, a US drone startup, believes that drones will not replace human decision-makers, but enhance the abilities of their human pilots.

For Google, the contract provides a scalable, next‑generation AI infrastructure pipeline, positioning it against rivals like Microsoft and Amazon in the race for AI compute dominance.

Breakthrough: Baking Sourdough with 5,000‑Year‑Old YeastScientists have successfully baked a sourdough loaf using yeast strains isolated from the 5,000‑year‑old Alpine mummy known as Ötzi the Iceman. The experiment demonstrates that ancient microorganisms can still perform modern fermentation processes.How the Ancient Yeast Was Extracted and TestedResearchers from Eurac Research's Institute for Mummy Studies carefully sampled the microbial layer on Ötzi’s skin and clothing, then cultured the yeast under cold‑room conditions before introducing it into a standard sourdough starter.Source: Ötzi’s preserved remains, discovered 1991 near the Italy‑Austria border.Age of yeast: ~5,000 years.Lead microbiologist: Mohamed Sarhan.Fermentation time: dough rose in 24 hours, comparable to modern baker’s yeast.Scientific Metrics: Fermentation Times and ViabilityThe ancient yeast produced a normal rise within 24 hours, indicating viable metabolic activity despite millennia of dormancy. No quantitative yield data were released, but the rapid leavening suggests comparable enzymatic efficiency to contemporary strains.Implications for Food Science and ArchaeologyThis result bridges paleomicrobiology and culinary science, offering a tangible link to prehistoric food practices. It also opens avenues for studying ancient microbial genetics, which could reveal lost fermentation traits.Next Steps: Brewing Beer and Expanding Ancient Microbe ResearchThe team plans to collaborate with German brewer Weihenstephan to test the yeast’s suitability for beer production. Further investigations will assess the genetic profile of the strain and explore other potential applications in food and biotechnology.
