Why JansBrief exists
Jan Stenbeck was the smartest person I ever met. Not smart in the way academics are smart. Smart in the way that changes the world. He saw what nobody else saw. He understood that mobile telephony would revolutionise countries that hadn't even laid copper wire yet. He broke state socialist monopolies when everyone said it was impossible. He built empires out of ideas.
Every day Jan received a binder. Two people read all the world's important newspapers and magazines for him and pulled out what mattered. The things others missed. The faint signals that foreshadow great change.
I worked with Jan. I learned from him. And I have never forgotten that binder. JansBrief is my tribute to him, a modern version: global, AI-driven, available to everyone with ambition.

Somewhere off the coast of the eastern United States, nineteen sharks are doing science. Fitted with small sensor packages that measure temperature, salinity and depth as the animals dive through the water column, they are generating oceanographic data from places where research vessels rarely go — and the results are striking. When their readings were fed into a leading ocean-climate model, forecast errors dropped by as much as 43 per cent.
The project, reported by Anthropocene Magazine, sits at the intersection of two problems that have quietly vexed climate science for decades. The first is observational: the ocean remains spectacularly under-sampled. The global Argo float network — roughly 4,000 autonomous instruments drifting through the world's seas — is the backbone of modern oceanography, but it leaves enormous gaps, particularly in coastal zones, shallow continental shelves and boundary currents where biological and economic activity is highest. Satellites see the surface. Floats sample the deep mid-ocean. The messy, dynamic margins in between are largely guesswork.
The second problem is computational. Ocean models are only as good as the data that initialises and corrects them. Feed a model sparse observations and it drifts — sometimes dramatically — from reality. Fisheries managers, shipping companies and coastal planners who depend on accurate sea-surface temperature and current forecasts are quietly absorbing the cost of that drift every day.
Enter the sharks. Unlike floats, which move passively with currents, sharks are intentional travellers. They cross temperature fronts, dive through thermoclines and patrol the continental shelf edge — precisely the zones models struggle with most. Their behaviour, it turns out, generates a complementary data set that fills the gaps floats leave behind.
This is not the first time marine animals have been recruited as oceanographers. Elephant seals, sea turtles and even albatrosses have carried sensors. But the shark study is notable for quantifying the model improvement so precisely and for focusing on commercially relevant coastal waters rather than remote polar seas.
The implications ripple outward. Better coastal ocean forecasts mean better predictions of fish stock movements, which matter enormously for the food security of nations from Senegal to the Philippines. They mean earlier warnings of marine heatwaves — the underwater equivalent of droughts — that can devastate coral reefs, kelp forests and aquaculture operations. And they offer a cheaper, scalable way to monitor oceans without deploying expensive new infrastructure.
There is a deeper lesson here too. The most elegant monitoring systems may not be engineered from scratch but grafted onto biological systems that already do what we need — move through the right places, at the right depths, at the right times. The sharks are not instruments. They are platforms.

Short term (now–12 months): Fisheries agencies in the western Atlantic could begin integrating animal-borne sensor data into operational forecasts within a year. The 43 per cent error reduction demonstrated in the study is large enough to change catch allocation models, potentially shifting quotas and seasonal openings for commercially important species. Coastal states along the US Eastern Seaboard, and those in West Africa sharing migratory fish stocks, would benefit first.
Medium term (1–3 years): Insurance and reinsurance companies pricing marine and coastal risk will take notice. As ocean models improve, the uncertainty margin in catastrophe models for coastal flooding, aquaculture loss and port disruption could narrow meaningfully. Expect pilot programmes pairing sensor-tagged apex predators with regional forecast centres in the Indian Ocean and Southeast Asia, where the Argo network is thinnest and economic dependence on fisheries is highest.
Long term (3–10 years): The principle — biology as infrastructure — extends well beyond sharks. If animal-borne sensors prove scalable, they could form a distributed, self-sustaining ocean observation network orders of magnitude denser than anything built from metal and plastic. Combined with AI-driven data assimilation, this biological mesh could transform climate modelling itself, closing the ocean data gap that remains one of the largest sources of uncertainty in global temperature projections.

El Salvador has launched the largest criminal trial in its history, putting 486 alleged leaders of the Mara Salvatrucha-13 gang before a court for ordering more than 29,000 killings between 2012 and 2022. President Nayib Bukele compared the proceedings to the Nuremberg trials. The mass prosecution is the culmination of Bukele's state-of-exception security policy, which has drawn both praise for reducing homicide rates and sharp criticism from human rights organisations over mass detentions and due process concerns.

China's electric-vehicle charging standard is becoming the global default in markets across Asia, Latin America and parts of Africa, yet it remains banned in the United States. Rest of World reports that the divergence is creating a fractured global infrastructure, forcing automakers to maintain parallel systems and raising costs for consumers in countries caught between the two ecosystems. The split echoes earlier format wars — VHS versus Betamax, GSM versus CDMA — but with far larger industrial consequences. Source: Rest of World · 6 May 2026
Israel allowed displaced Gazans to begin crossing the military zone that bisects the enclave, after a deadlock over hostage releases was broken. The Wall Street Journal reports that thousands of Palestinians walked north through corridors flanked by Israeli armour, carrying what possessions they could. The movement is the largest return since Israel sealed the crossing months ago, but northern Gaza remains largely in ruins, with minimal infrastructure to receive the returnees. The crossing signals a fragile shift in the conflict's dynamics, though it falls far short of a permanent ceasefire. Source: Wall Street Journal · May 2026
Mainstream conservatives in Andalusia fear that coalition deals with the far-right Vox party could force them toward an exclusionary "Spaniards first" policy on public services, housing and employment. Politico Europe reports the dynamic is becoming a template across Spanish regional politics: centre-right parties need Vox's seats to govern but risk alienating centrist voters and immigrant communities essential to the region's agricultural economy. The Andalusia vote is being watched as a bellwether for whether Europe's migration-hardline parties can translate electoral gains into binding policy. Source: Politico Europe · 6 May 2026
China's financial regulator has instructed the country's largest banks to temporarily suspend new lending to five refiners recently sanctioned by Washington over their ties to Iranian oil, Bloomberg reports. The directive marks a rare instance of Beijing appearing to accommodate American secondary sanctions rather than defy them — a calibration that reflects the delicate balancing act China faces between maintaining its energy supply and avoiding broader financial isolation. The move will ripple through Asia's oil-trading networks and could tighten crude supply for independent Chinese refineries that have become major buyers of discounted Iranian barrels.

A South Korean appeals court reduced former prime minister Han Duck-soo's prison sentence from 23 to 15 years for his role in ex-president Yoon Suk-yeol's brief martial law declaration in December 2024. The ruling signals the judiciary is recalibrating punishments as the country's political crisis slowly normalises, though critics say 15 years remains harsh for someone who acted under presidential orders.

One year into Friedrich Merz's chancellorship, Germany's military spending is rising sharply but the chancellor's impolitic leadership style — including a public spat with Donald Trump — is undermining Berlin's ability to translate money into influence. Monocle reports that Merz's tactlessness has alienated allies at a moment when Europe needs German diplomatic weight most. The assessment suggests that Germany's fortunes are unlikely to improve without a shift in tone at the top. Source: Monocle · May 2026
Fernand Kartheiser, a Luxembourgish member of the European Parliament expelled from his political group after visiting Russia, is now actively recruiting other MEPs for a return trip.

Silo, a Finnish startup founded by a quantum physicist, has raised €25 million to build what its backers call "the Palantir of quantum computing" — an operating-system layer that lets enterprises run algorithms across different quantum hardware without being locked into a single provider. Sifted reports the company emerged from Tier 2 European tech hubs, far from the usual London-Paris-Berlin axis.
Jan Stenbeck understood platform plays before most people understood platforms. When he built Millicom, the insight was not that mobile telephony was valuable — everyone knew that — but that owning the connective layer in markets others ignored would generate outsized returns. Silo's bet is structurally similar: quantum hardware is expensive, fragmented and improving fast, which means the real value may sit not in the machines but in the software that makes them interchangeable.
The company's pitch to enterprise customers is simple: don't bet on one quantum computer manufacturer. Write your code once, deploy it on whichever hardware is best for each task, and switch when something better arrives. It is the cloud-computing playbook applied to a technology most enterprises still regard as science fiction.
At €25 million the company is small. But platform layers in nascent industries tend to either die quietly or become indispensable. There is rarely a middle outcome. Jan would have recognised the asymmetry — and probably would have written a cheque.

Vienna's Burgtheater has opened its prized Gustav Klimt ceiling paintings to public tours — not from the auditorium floor but from the restoration scaffolding itself, allowing visitors to stand centimetres from work normally seen only as distant decoration. The paintings, completed in 1888 when Klimt was still a young decorative artist, predate his golden period by more than a decade. The scaffolding tours run during the current restoration and offer an extraordinary intimacy with surfaces no living viewer has seen at this proximity. Source: Artnet News · May 2026
Christophe Leribault, the Louvre's new director, has laid out his plans for the museum's transformation. "The Louvre is entering a period of transformation," he said, signalling changes to visitor flow, gallery rotation and digital access. Leribault takes the helm at a moment when the world's most visited museum is reckoning with both security vulnerabilities exposed by a recent heist and the challenge of making an encyclopaedic collection relevant to a generation raised on screens.

On the Bowery, curator Tony Cox runs Club Rhubarb, a nomadic gallery project that presents a gritty, deliberately uncommercial version of the "old" downtown. Its latest exhibition occupies an unassuming walk-up — no white walls, no press previews, no collector dinners. Wallpaper* calls it New York's most experimental gallery. In an art market increasingly dominated by mega-galleries and fairs, the walk-up model is a quiet act of resistance. Source: Wallpaper · May 2026
The James Beard Foundation has announced its full slate of 2026 award finalists across restaurant, chef and media categories.

New Scientist reports that an analysis of 150 artefacts from a copper-mining site in Wales shows that Bronze Age Britons continued fashioning mining tools from bone even after they had mastered metalworking. The finding complicates the neat narrative of technological replacement and suggests that older materials persisted not out of ignorance but because they worked for specific tasks — a reminder that innovation and tradition coexist more often than textbooks admit.

Monocle highlights three exhibitions in Tokyo that capture the city's cultural range this season: the reopened Edo-Tokyo Museum, which traces the capital's transformation from shogunal seat to modern metropolis; the new Mon Takanawa gallery space; and Nonlecture, an intimate books-and-arts venue. Together they offer a portrait of a city that treats its past not as heritage decoration but as living material — constantly reinterpreted, rearranged and made relevant. For visitors planning a spring trip, the trio represents a quieter, more considered Tokyo than the neon-and-ramen circuit most guidebooks sell. Source: Monocle · May 2026 ---
Malaysia is confronting a new category of financial fraud: AI-powered attacks on its real-time payment infrastructure. Nikkei Asia reports that the country's rapid adoption of instant payment systems has outpaced its security architecture, creating vulnerabilities that sophisticated AI tools — deepfake voice authorisation, synthetic identity generation — are beginning to exploit. The challenge is not unique to Malaysia, but the country's combination of high digital-payment penetration and relatively thin cybersecurity talent makes it an early canary. Regulators across Southeast Asia are watching closely, as similar instant-payment systems in Thailand, India and the Philippines face comparable exposure. Source: Nikkei Asia · May 2026
MIT Technology Review has published a long-form argument that AI could be the most powerful tool for democratic governance since the printing press — if designed deliberately for that purpose. The piece argues that every major shift in information technology has reshaped political systems: the printing press enabled the Reformation and representative government; the telegraph built the bureaucratic state; broadcast media created national audiences. AI, the authors contend, could either concentrate power further or distribute it — depending on whether democratic institutions invest in participatory AI tools or cede the technology to authoritarian and corporate actors. The analysis is less a prediction than a design brief, outlining specific mechanisms by which AI could improve deliberation, representation and accountability.

Two inexpensive, neon-coloured submersibles began descending nearly 6,000 metres into the Pacific last week, in what MIT Technology Review calls a potential turning point for deep-sea access. Unlike traditional deep-ocean vehicles costing tens of millions, these submersibles are designed for affordability and repeatability — hopping across the seafloor on multiple dives rather than making rare, expensive descents. The democratisation of deep-sea access cuts both ways: it could accelerate marine science enormously, but it also lowers the barrier for deep-sea mining operations that environmental groups have fought to constrain.

43
43%
That is the reduction in ocean forecast errors when data from sensors carried by nineteen sharks off America's east coast was incorporated into a leading climate model. The number comes from a study reported by Anthropocene Magazine and it captures something important: the ocean observation network humanity depends on for climate, fisheries and shipping forecasts has enormous blind spots, and biology may be the cheapest way to fill them. The global Argo float network costs roughly $30 million a year to maintain. Tagging a shark costs a few thousand dollars. Nineteen animals delivering a 43 per cent improvement in coastal model accuracy suggests a cost-effectiveness ratio that should make every oceanographic funding agency sit up. If the approach scales — to hundreds of tagged animals across multiple species and ocean basins — it could fundamentally alter how we monitor the two-thirds of the planet covered by water.

8 — Today's Wisdom
Nineteen sharks with sensors on their backs reduced the margin of error in one of the world's leading ocean models by 43 percent. Not by building new infrastructure, not by launching more expensive research vessels, but by leveraging animals that already move through exactly the waters where we need data. It's one of the most beautiful innovations I've seen in a long time, and it says something fundamental about how we should think about problem-solving in general.
We have a reflex in society to meet every challenge with large, centralized systems. More satellites, more sensors, more government agencies, more budget lines. Sometimes that's the right call. But often there are already existing systems, biological or human, moving through the world in precisely the way we need. The trick is to see them and layer on a thin veneer of technology that turns their natural behavior into usable information.
It's the same logic that drives the best platform companies. You don't build everything yourself. You find what already works and make it visible, measurable, scalable. The sharks aren't instruments. They're platforms. And that insight should shape how we think about everything from climate monitoring to healthcare to education. The most elegant solutions rarely start with a blank sheet of paper. They start with seeing what's already there and asking yourself why we're not using it.
