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.

A bat disease is repricing municipal debt in the United States — and in doing so, it has accidentally created a new asset class for conservation finance.
White-nose syndrome, caused by the fungus Pseudogymnoascus destructans, has killed an estimated 6.7 million bats across North America since it was first detected in a New York cave in 2006. The disease has now spread to 40 US states and eight Canadian provinces. Bats are not cuddly. They do not feature on donation envelopes. But they are voracious consumers of agricultural pests — a single colony can eat tonnes of insects per season — and their disappearance has measurable economic consequences.
New research published this month quantifies something that ecologists have long suspected but never pinned to a dollar figure: counties that have lost bat populations to white-nose syndrome are paying higher yields on their municipal bonds. The mechanism is straightforward. Fewer bats mean more crop pests. More pests mean higher agricultural costs and lower farm revenues. Lower revenues mean a weaker tax base. A weaker tax base means higher credit risk for the county. And higher credit risk means investors demand a premium.
The yield spread is not trivial. Affected counties are paying measurably more to borrow — a cost that compounds over decades of infrastructure financing. The researchers used the staggered geographic spread of the fungus as a natural experiment, comparing bonds issued by similar counties before and after bat die-offs, controlling for other economic variables. The correlation held.
Here is where the story turns from grim ecology to financial innovation. If bat loss raises borrowing costs, then bat conservation lowers them. That creates a quantifiable return on investment for wildlife protection — not in the fuzzy language of "ecosystem services" but in the hard currency of basis points. Conservation groups and municipal finance specialists are now exploring whether this framework can be used to structure green bonds or conservation credits tied directly to bat habitat restoration. An investor who funds a bat recovery programme could, in theory, capture value from the resulting decline in municipal borrowing costs.
This matters beyond bats. The research establishes a template for linking biodiversity loss to financial risk in a way that bond markets — the most conservative, least sentimental corner of finance — can understand. If a cave fungus can move yields, so can deforestation, pollinator collapse, or wetland destruction. The implication is that nature risk is already priced into debt markets; we just have not been reading the signals.
The bat-bond nexus will not make headlines the way a rate decision does. But it may quietly reshape how governments, insurers, and investors think about the economic value of species that nobody thinks about — until they are gone.

Now — A cave fungus hands municipal treasurers a reason to fund ecology: Environmental advocates have spent decades trying to monetise ecosystem services. Most attempts produce reports that sit on shelves. The bat-bond research is different because it uses a market instrument — municipal debt — that involves real money, real counterparties, and real legal obligations. When a county treasurer sees borrowing costs rise because of a fungus, conservation stops being a line item in a sustainability report and starts being a fiscal risk factor. Expect municipal ratings agencies to begin asking questions about ecological exposure in their assessments.
Soon — Biodiversity-linked financial products emerge: The template is replicable. If bat loss reprices county debt, researchers will race to document parallel effects: pollinator collapse and agricultural bonds, coral reef degradation and coastal property insurance, forest loss and watershed utility bonds. Within two to three years, we are likely to see the first explicitly biodiversity-linked municipal bonds — instruments where proceeds fund habitat restoration and returns are tied to measurable ecological recovery. The sustainable finance world has been waiting for a credible bridge between species data and financial returns. This is it.
Later — Fiduciary duty expands to include ecological exposure: The longer arc points toward mandatory natural-capital accounting. The EU's Corporate Sustainability Reporting Directive already gestures in this direction, but the bat-bond research provides the empirical backbone. If biodiversity loss is a material financial risk — demonstrable in bond spreads — then fiduciary duty requires its disclosure. Within a decade, a company or municipality that fails to account for its dependence on intact ecosystems will be treated the way one that ignores climate risk is treated today: as recklessly under-informed.

A Der Spiegel investigation reveals how Russian agents are recruiting Kenyan men under false pretences — promising truck-driving jobs or athletic competitions — then forcing them to fight on the front lines in Ukraine. One man believed he was being hired as a driver; another was told he would compete in a running race. Both ended up in combat zones with no way out. The report adds to growing evidence that Russia's manpower shortage is driving predatory recruitment across Africa and South Asia, targeting vulnerable men in countries with high unemployment and weak consular protection. Nairobi has been slow to respond, though pressure is building domestically as families demand answers. Source: Der Spiegel · 21 May 2026
Nicolás Maduro Guerra, son of Venezuela's imprisoned former strongman, has given his first interview to a Western outlet. Speaking to Der Spiegel, he acknowledged his father's "mistakes" and admitted underestimating American power. The interview is remarkable less for its content — the younger Maduro offers few concrete policy positions — than for its existence. That the family is now engaging with Western media suggests a calculation that total isolation is no longer tenable. Venezuela remains in deep crisis, with humanitarian conditions dire and political resolution distant. Source: Der Spiegel · 21 May 2026
Survivors of the catastrophic Sumatra floods are filing a lawsuit against the Indonesian government, alleging inadequate disaster preparation and recovery. The legal action, reported by Al Jazeera, marks a growing trend across Southeast Asia: citizens using courts to hold governments accountable for climate-related disasters. Indonesia's disaster-management agency has faced persistent criticism for underfunding early-warning systems in provinces outside Java. The case could set a precedent for climate litigation in a country that ranks among the world's most disaster-prone. Source: Al Jazeera · 21 May 2026
Brazil's Federal Public Prosecutor's Office has recommended that the country's sole uranium mine — operating since 1999 in Caetité, Bahia — not have its environmental licence renewed until the operator conducts proper community consultation. The move could leave Latin America's largest country without domestic uranium production at a moment when nuclear energy is experiencing a global renaissance. Brazil operates two nuclear reactors and has a third under construction. Dependence on imported uranium would add both cost and geopolitical vulnerability. Source: Mercopress · 21 May 2026
Carbon Brief reports that the number of new coal-fired power plants built globally in 2025 hit its highest level in ten years, driven overwhelmingly by China and, to a lesser extent, India and Indonesia. Yet total coal power output still declined, as retirements in Europe and North America and lower utilisation rates offset the new capacity. The paradox captures the messy reality of the energy transition: the world is simultaneously building more coal plants and using coal less. The risk is that newly built plants, once operational, create political and financial pressure to keep running for decades. Source: Carbon Brief · 20 May 2026
Argentina's President Javier Milei has signed a letter of intent allowing US Southern Command to patrol the South Atlantic alongside Argentine forces for the next five years. The agreement, framed under the Pentagon's Programme 333, represents the deepest military cooperation between Buenos Aires and Washington in decades. It is also a stark departure from Argentina's traditional posture of strategic non-alignment. The move will unsettle Brazil, which views the South Atlantic as its sphere, and comes as Milei seeks every possible lever of US support amid a fragile economic stabilisation.

The US Department of Justice has charged former Cuban leader Raúl Castro and five others with conspiracy to murder US nationals, murder, and destruction of aircraft over the 1996 shoot-down of two civilian planes flown by the Miami-based exile group Brothers to the Rescue. The charges, filed nearly three decades after the incident, are politically charged: they land as Washington tightens its posture toward Havana and as Cuba's economy deteriorates to its worst point since the 1990s Special Period. The indictment has no realistic path to arrest or trial, but it signals that the current US administration intends to keep maximum legal and symbolic pressure on Cuba's ruling establishment.

Reliance Industries' plan to list its digital arm Jio Platforms — potentially India's largest-ever initial public offering — is running into obstacles exacerbated by the war in Iran. Bloomberg reports that the conflict has rattled investor appetite for Indian assets broadly, while rising energy costs threaten Reliance's refining margins. Jio's telecom and digital services business remains strong, but the IPO timing now looks fraught. A delay would disappoint the Indian government, which has been counting on marquee listings to deepen domestic capital markets and project economic confidence. Source: Bloomberg · 21 May 2026 ---
Boston Metal started with an audacious bet: use molten oxide electrolysis — essentially passing electricity through molten rock — to make steel without coal. The Massachusetts-based startup, spun out of MIT, has spent years refining a process that replaces the blast furnace's carbon chemistry with clean electrons. The steel industry accounts for roughly 8 per cent of global greenhouse emissions. Decarbonising it is one of the hardest industrial problems on Earth.
Now comes the pivot that makes the story interesting. Boston Metal has just raised $75 million — not for steel, but for critical metals. The same electrolysis platform that can produce green steel turns out to be exceptionally good at extracting metals like chromium, niobium, and vanadium from complex ores and waste streams that conventional smelters cannot handle economically. These are the metals that underpin everything from jet engines to grid batteries to semiconductor manufacturing — and their supply chains are dominated by a handful of countries, chiefly China.
The elegance is in the dual use. One core technology, developed to solve an environmental problem, now addresses a geopolitical one. Western governments are spending billions trying to build alternative supply chains for critical minerals. Most of that money flows toward mining — digging new holes in new places. Boston Metal's approach is different: it can extract value from mining waste, industrial slag, and low-grade ores that sit in tailings ponds around the world, already dug up and already ignored.
The company is not yet profitable. The technology works at pilot scale but has not been proven at full industrial volume. These are real risks. But the pattern is unmistakable: a small team with a core technical insight found a way around an entrenched industrial structure, then discovered that the same tool opened a second door nobody had planned for. That is how disruption actually works — not through grand strategy but through opportunistic discovery by people who understand their own technology deeply enough to see adjacent possibilities.
In an era when most critical-minerals policy consists of governments writing cheques to established mining companies, a startup that proposes to get the same metals out of waste piles with clean electricity is exactly the kind of asymmetric bet that deserves attention.

Sotheby's modern art evening sale in New York totalled $303.4 million — comfortably exceeding its May 2025 result — despite lacking the kind of trophy lots that typically drive auction headlines. The buoyancy came from depth rather than spectacle: strong bidding across mid-market works by established names, with few lots going unsold. The result suggests that the art market's top tier is healthier than the prevailing narrative of contraction implies, at least for blue-chip modern material. Meanwhile, across town at Christie's, works from dealer Marian Goodman's collection — including major Gerhard Richters — brought $162.7 million. Together, the week signals that institutional-quality art continues to find willing buyers even in uncertain economic conditions. Source: Artnet News · 20 May 2026
Kengo Kuma & Associates, in collaboration with Field Operations and Schwartz/Silver Architects, has unveiled designs for an expansion of the Brandywine Conservancy & Museum of Art outside Philadelphia. The project deploys Kuma's signature approach — natural materials, permeable boundaries between inside and outside — in a landscape synonymous with the Wyeth painting dynasty. The vernacular design responds to the rolling Brandywine Valley rather than imposing a Tokyo aesthetic on Pennsylvania farmland. It is Kuma's first museum building in the US, a milestone for a practice that has built over 300 projects worldwide. Source: Dezeen · 20 May 2026
Además Arquitectura has completed Casa Alba II in Buenos Aires's Ezeiza-Canning neighbourhood: a blocky concrete residence wrapped by a curved privacy wall that traces the corner of the lot. The wall creates an "introspective approach" — the house turns inward, generating its own courtyard microclimate in a sprawling suburban grid. At 248 square metres, it is modest by Argentine standards, but the spatial trick of the enclosing wall gives it a generosity that belies its footprint. A reminder that the most effective architecture often subtracts rather than adds. Source: Dezeen · 20 May 2026
In a feature by Eater, a worker-owned sandwich shop operates on a sliding-scale pricing model — customers pay what they can. The shop functions as a cooperative, with decisions made collectively and profits shared. It is not a charity; it is a business model designed to survive in a neighbourhood where a conventional café would either gentrify or die. The piece details the mechanics: how the cooperative sets its price floor, handles freeloaders, and still turns enough surplus to pay living wages. It is an economics lesson disguised as a lunch order. Source: Eater · 20 May 2026
New Scientist reports on a finding that may reshape how clinicians monitor women's health: female body temperature rises gradually and consistently from the late teens through the early forties. The pattern is independent of menstrual cycle fluctuations and appears to reflect deeper metabolic ageing. Researchers suggest the temperature curve could serve as a low-cost biomarker for overall health and ageing trajectories — a simple thermometer reading potentially carrying more information than we realised. The study opens questions about sex-specific baselines in medicine, an area that remains chronically under-researched. Source: New Scientist · 20 May 2026
The Late Show with Stephen Colbert ends its run this week, the latest casualty in the slow erosion of American late-night television as a cultural institution. NRC Handelsblad frames the shutdown within a broader pattern under the Trump era: critical media voices disappearing not through censorship but through commercial attrition and audience fragmentation. Whether you loved or loathed late-night's political turn, the format served as a nightly commons — a shared reference point in a country with fewer and fewer of them. Its absence will be felt less as a loss of comedy than as a loss of ritual. Source: NRC Handelsblad · 21 May 2026 ---
Anthropic has told investors it expects its first profitable quarter, with annualised revenue on track to more than double to around $10.9 billion. The milestone matters less for Anthropic specifically than for what it signals about the AI industry's economics. Until now, the dominant narrative has been that foundation-model companies burn cash indefinitely — that they are research labs, not businesses. Anthropic's path toward profitability, achieved before OpenAI and xAI, challenges that assumption. The key factor appears to be enterprise contracts: businesses paying for reliable, safe AI systems rather than consumers using free chatbots. If the enterprise revenue model works, it validates the approach of building fewer, more carefully aligned models rather than racing to release the flashiest consumer product. It also raises the stakes for OpenAI's planned IPO, now reportedly being prepared for as soon as September with a target valuation of $1 trillion. If Anthropic can be profitable at a fraction of that valuation, investors will ask hard questions about what the premium buys. Source: Financial Times / TechCrunch · 21 May 2026
Nature's latest breakdown of its Nature Index reveals that Chinese institutions now account for nearly half of the world's highest-impact chemistry research — a share that has grown rapidly over the past decade. The dominance is not limited to applied industrial chemistry; it spans organic synthesis, materials science, catalysis, and electrochemistry. The implications ripple far beyond academia. Chemistry is the foundational science for pharmaceuticals, batteries, semiconductors, and advanced materials. A country that leads in chemistry research today leads in industrial innovation tomorrow. For Western policymakers focused on AI and semiconductors, the data is a reminder that competitive advantage in technology begins in the lab, not the fab — and that China's scientific base is now broad enough to sustain industrial leadership across multiple sectors simultaneously.

Tesla has activated its Full Self-Driving (Supervised) system in China, one week after Elon Musk visited the country alongside President Trump. The rollout arrives in a market where Level 3 autonomous driving is already legal and domestic competitors — Huawei, Xpeng, BYD — have been shipping advanced driver-assistance systems for months. The competitive dynamics are inverted from the US: in China, Tesla is the latecomer. The launch will test whether FSD's data advantages from American roads translate to Chinese driving conditions — a fundamentally different environment of dense urban traffic, electric scooter swarms, and road-marking conventions that American training data may not capture. For Tesla, it is less a victory lap than an entrance exam. Source: South China Morning Post · 21 May 2026 ---

That is the share of the world's highest-impact chemistry research now produced by Chinese institutions, according to the latest Nature Index. A decade ago, the figure was closer to 15 per cent. The acceleration reflects a deliberate national strategy: massive investment in university labs, aggressive recruitment of overseas Chinese scientists, and a funding model that rewards publication volume in top-tier journals.
But the number also connects to today's Signal in a less obvious way. If biodiversity loss is becoming a financial variable — as the bat-bond research suggests — then the science needed to understand, monitor, and reverse that loss is itself a strategic resource. Ecological chemistry, environmental genomics, biosensor development: these are fields where China's research dominance means it will increasingly set the terms of global environmental science. The countries that understand molecular ecology best will be the ones that build the most credible biodiversity-finance instruments. A cave fungus reprices bonds in Ohio. The lab that sequences that fungus fastest may be in Hefei.

Boston Metal started out making steel without carbon. Now it turns out the same technology can extract critical metals from mining waste that nobody wanted to touch. This isn't a pivot in the usual sense of the word. It's what happens when engineers understand their own technology so deeply that they see doors no one else knows exist.
I've built three companies that reached billion-dollar valuations, and I recognize the pattern. The truly interesting discovery almost never comes out of a strategic plan. It comes from someone with their hands deep in the technology who suddenly realizes the tool they built solves a problem they hadn't thought of. Not because they were smart enough to plan for it, but because they were close enough to see it.
The entire Western world's minerals policy right now is about opening new mines, writing big checks to established companies, and hoping China doesn't get there first. That's the slow road. The interesting road is a small team in Massachusetts proposing that we can recover the same metals from waste piles that already exist, using clean electricity, without digging a single new hole.
There's a lesson here that extends far beyond metallurgy. The best climate policy, the best security policy, the best industrial policy isn't built by bureaucrats allocating money. It's built by people who understand their technology well enough to follow it wherever it leads.
