Everything is contagious, even the way we listen and understand. For humans, consonants usually carry more information than vowels. This pattern appears in many languages: when a sentence is stripped down to its bones, those bones are more recognizable if consonants dominate. That is why Spanish has 23 consonants and five vowels, a ratio that holds in almost every language. It is also why people drop vowels when they want to save characters in a message. Our brains fill in the gaps more effectively.
The label for Humira, once the best-selling drug in the world, lists its risks in plain print. One of them, in the label’s own words, is new “autoimmune” disease.
A drug prescribed for a condition labelled autoimmune carries a warning that it can cause a condition labelled autoimmune. That contradiction sits in every box, on a folded paper almost nobody reads.
My new book starts there.
No Autoimmunity: The Body Doesn’t Attack Itself
For seventy years, “your body is attacking itself, and we don’t know why” has ended the conversation for people diagnosed with multiple sclerosis, lupus, rheumatoid arthritis, Hashimoto’s, Type 1 diabetes, Crohn’s and psoriasis. More than eighty conditions now carry the autoimmune label. The diagnosis comes with a prescription for life. It almost never comes with a question about cause.
This book asks the question and answers it from the framework’s own records: its drug labels, its journals, its regulatory filings, and its own experiments.
What’s inside
Humira: The Cover Story. A drug that once earned more than twenty billion dollars a year, whose own label warns of lymphoma and new conditions labelled autoimmune. Stop taking it and the symptoms usually return, so the prescription never ends.
The Autoimmune Label. In 1956 researchers produced thyroid disease in rabbits by injecting thyroid tissue with a powerful adjuvant. A category defined by “unknown cause” has since grown to more than eighty conditions.
The Three Deceptions. The “immune system” as an army, antibodies as soldiers, autoimmunity as the army turning on itself. Each idea props up the others.
Richet’s Erased Nobel. The 1913 Nobel Prize for showing that injected foreign proteins sensitise the body. Medicine kept the prize and filed the warning under “allergy.”
The Nervous System. The 1976 swine flu campaign and the paralysis cases that followed. Hal Huggins removed mercury fillings from MS patients, documented their improvement, and lost his licence.
The Endocrine System. Fluoride and bromide crowding out iodine, and a lifelong thyroid pill that ensures nobody learns whether the gland could recover.
Connective Tissue. Evelyn Hess’s catalog of more than seventy medications that produce lupus and related disease, which usually clears once the drug is stopped. The book’s central proof, from the framework’s own literature.
The GI Tract. Celiac disease went from one child in five thousand in 1950 to about one person in a hundred today. The chapter covers what changed in the food.
Skin and Blood. Psoriasis appears where skin is injured, and the drugs sold for psoriasis are documented to cause it.
The Documented Reversals. Drugs withdrawn, mercury removed, implants taken out, diets changed. Once the injury is gone, the body mends.
What Made the Reversal Possible. Remove the harm, restore what the body needs, give it time, and protect what still works.
How to Think About the Diagnosis You Were Given. Written directly to the reader holding a diagnosis, with the exposure history to build and the questions to ask.
Where to Go from Here. A reading list and the kinds of practitioners worth finding.
Every chapter closes with How to Explain It to a 6 Year Old, a plain-language section you can read aloud to a child or hand to a relative who will never read a medical paper. The book also includes a glossary, a bibliography of more than 100 sources and a full index.
Who this book is for
If you or someone you love has been handed one of these diagnoses, read this before accepting that the answer is a lifetime prescription. If you’re a practitioner, or someone who simply wants to check the record, the full documentary trail is here, referenced source by source.
Roughly 315,000 years ago, a group of early humans lived in what is now Morocco. Their remains, unearthed at a site called Jebel Irhoud, are the oldest fossils ever attributed to our species, Homo sapiens. Now, an international team of researchers has digitally reconstructed the face of one of these individuals, building a composite skull […]
Finding fossils usually means months of fieldwork, a hammer, and a lot of patience. In Finnmark, Norway’s northernmost region, it took none of that. According to the University of Cambridge, a cluster of rocks had broken loose from a cliff above a sheep field. When they split open on landing, they exposed a fossil of […]

Quarks, the smallest known building blocks of matter, are never seen alone. They are roughly a billion times smaller than an atom and exist only locked inside larger particles such as protons and neutrons — no one has ever observed one in isolation. That impossibility has a name, confinement, and a strange consequence: try to […]

An international team of astronomers has published a detailed study of VT J1906+0849, a radio source discovered in the VLASS survey (Very Large Array Sky Survey) that doesn’t resemble anything else previously catalogued in the Milky Way. The paper, led by Jessie M. Miller of the California Institute of Technology, combines radio, infrared, optical, and […]
Somewhere between an electron and a human being, the rules of physics change. Quantum mechanics allows an atom to exist in two states simultaneously — spinning left and right at the same time, for instance — which is impossible to picture at human scale.

Earth has never been a perfect sphere. It bulges slightly at the equator and flattens slightly at the poles, a shape geodesists call an oblate spheroid — think of a basketball very gently squeezed from top and bottom. That bulge isn’t fixed, though, and a new study published in the Journal of Geophysical Research: Solid […]
There’s a temperature nothing in the universe has ever touched. It’s called absolute zero, equal to -273.15°C (-459.67°F), the point at which the particles that make up matter would lose all their kinetic energy and simply stop moving. In 1848, the British physicist William Thomson — better known as Lord Kelvin — proposed making that […]
One grape variety still grown in Spanish vineyards, hebén, has never gone out of cultivation for at least the last 1,100 years, according to the new study. That takes its lineage back to roughly the year 929, around when the Caliphate of Córdoba was proclaimed in southern Spain. Eleven centuries of unbroken agriculture, and the […]
In February 2012, after twenty years of nearly uninterrupted work, a Russian drill broke through the last stretch of ice over East Antarctica and reached something no human had ever touched: the surface of a lake sealed shut long before our species existed.

On October 9, 2022, two space telescopes, Swift and Fermi, picked up the brightest gamma-ray burst ever recorded. Researchers nicknamed it BOAT — “brightest of all time” — official designation GRB 221009A. The explosion happened in a galaxy roughly 2 billion light-years away, which means its light set out across space before complex life had […]
For more than four months, Brian, a commercial fisherman in his late 40s, had been waiting for the weather conditions to be right for us to go fishing outside Bagenkop, a small harbor town on the southern tip of the Danish island of Langeland.
“One more problem has come up,” Brian told me over the phone in early May. “I have lost my fishing license." He was no longer allowed to sell fish for a living. Instead of preparing his boat to go out to sea and to show me how fishing in Denmark had changed over his lifetime, Brian was now removing the registration number from its hull.
Across Denmark, coastal fishing communities are shrinking as catches decline. At the same time, warming seas, overfishing and pollution are putting increasing pressure on marine ecosystems.
“Plenty of fish in the sea”? Not anymore, say UN experts, with 35% of the world’s marine fish stocks being fished faster than they can be biologically replaced. Today, more than half of the fish we consume worldwide comes from fish farms.
This summer, sea temperatures along Denmark’s beaches reached 28 degrees Celsius, a record high. On September 2, the UN Environment Program warned that the world is likely to cross 1.5 C of warming above pre-industrial levels within the next few years. As the climate warms, the pressure on marine ecosystems grows.
In August, Iceland voted not to restart accession talks with the European Union, in part because of concern that it would lose sovereign control of its fishing industry. While fishing is not as major a part of Denmark’s GDP as it is Iceland’s, the EU’s impact has meant independent Danish fishermen have struggled to survive in the face of corporate competition.
For Brian, though, it’s about more than regulations. It is about watching the ocean he grew up with slowly disappear.
Nets covered in black slime
His story reflects a larger shift happening along the Danish coastline. Coastal fishermen, once a central part of the country’s history, are a vanishing breed.
For Brian, it was never about the money. Even when he was a teenager and he told his father he wanted to be a fisherman, his father said it was a bad idea. But the pull of the sea was irresistible. His life as a fisherman began as a hobby, accumulating experience and knowledge just by spending as much time as possible on water. He learned how to read the currents, the weather, and fish movements through experience rather than education. In 2019, despite the uncertainty surrounding the industry, he bought a commercial fishing boat. “When I started as a teenager, there were fish everywhere,” he said. But over the years, the numbers have dwindled starkly. Every few years, another Danish harbor became economically unsustainable. First Bogense, then Kerteminde, later Nyborg and Spodsbjerg. Each one of them followed the same pattern: fewer fish, declining landings, and growing questions about whether it was possible for small fisheries to continue their operations.
While working on this story, I spoke to ten small-scale Danish fisheries across the country. Half of them said they do not expect to still be fishing five years from now. In 2019, they said, ten nets could bring in between 150-200 kilos of plaice on a single trip. Two years later, the same nets would return with only two kilos. As the catches became smaller, so did the possibility of keeping a commercial license. Brian no longer caught and sold enough fish to keep his permit.
One day still stands out to him as perhaps the single worst he has experienced at sea. He had three nets in the water. The first one he hauled in looked normal. The second held fewer fish than expected. Then he started pulling in the third — the net was completely empty and covered in thick, black slime.
Marine biologist Stiig Markager told me that what Brian saw was a tell-tale sign of oxygen depletion. In 2025, around 40% of Danish marine areas were affected by low oxygen levels. Oxygen depletion happens when too many nutrients, mainly nitrogen and phosphorus from agriculture and wastewater, enter the sea. These nutrients fuel large algae blooms.
When the algae die and sink to the seabed, bacteria begin decomposing them, consuming enormous amounts of oxygen in the process. Climate change exacerbates the problem. “Warmer water contains less oxygen. At the same time, biological processes speed up when temperatures rise.” In practice that means algae grow faster, oxygen is consumed more quickly, and deep waters struggle to recover. Together, these processes reinforce each other. “When oxygen disappears, it damages the seabed ecosystem,” Markager said.
A new global study argues that aquatic deoxygenation is approaching an “unsafe space” and should be considered a potential tenth planetary boundary. The global ocean has lost around 2% of its oxygen over the past 50 years. The consequences for marine life are catastrophic, forcing either flight or suffocation.
Marine biologists have studied oxygen depletion in the Danish seas for decades. But, Brian says, “fishers are often the first people to see the effects of that depletion, directly in their nets.” It is a first-hand experience, fishers say, that is often discounted or ignored. Many independent coastal fishers say they feel increasingly excluded from political conversations about the ocean, despite spending their working lives at sea.

“It feels like we’re not really welcome anymore,” Brian said. He believes small-scale fisheries like his are being pushed out while decisions about the seas are increasingly made by those on land. “I think they don’t want so many people out there seeing what’s actually happening.”
For years, debates about oxygen depletion in Denmark have become deeply political. Marine scientist Stiig Markager says that the results of environmental research have repeatedly clashed with agricultural and political interests. “There is complete opposition from agriculture and from Venstre (a major center-right political party) to making research publicly available,” he said. “There is a clear political strategy from Venstre that there must be no interference with agriculture.”
According to Markager, tensions between environmental researchers and agricultural interests intensified during the early 2000s, as scientists linked nitrogen runoff from farming to oxygen depletion in Danish waters. Despite decades of plans and political promises, Markager says, the recovery many researchers hoped for never fully arrived.
For this story, I also contacted both the Minister of Environment and the Minister for Food, Agriculture and Fisheries to ask for an interview about the state of Danish waters and the future of small-scale fishing. Neither had time to answer questions.
“When I started as a teenager, there were fish everywhere.” Brian said in BK Kar“Fishers are often the first people to discover oxygen depletion, directly in their nets,” Brian explained."I have lost my fishing license," Brian said on a phone call.
What remains is behind glass
One harbor that has felt the impact of the changing nature of Danish waters is Bønnerup Strand, which has transformed from a fishing town into a tourist destination. The harbor now features an ice cream shop, a hot dog kiosk, a seafood restaurant, and a mini golf course. The iconic blue Danish fishing boats are conspicuous only by their absence. Instead, boats built for leisure, not commercial fishing, are docked at the harbor.
Along the quay, an outdoor exhibition has been installed behind glass panels. It started last year, created by a local group of volunteers trying to preserve what Bønnerup Strand used to be. The pictures show fishing nets piled high, men in blue overalls, boats unloading their catch, and fish laid out in crates.
Movement. Noise. Purpose. It was a harbor bustling with life. Hans, in his 60s now, was once a fisherman in Bønnerup Strand. He walks past the diorama and tells me that twenty years ago “there were 60 or 70 fishing boats here, now there are two.” Some of the independent fishers chose to leave, their lives no longer making economic sense. Others lost their licenses. The rest have disappeared, not all at once, but gradually. Some left before it was too late, others had their boats seized by the bank when their revenue became too low. “Quite a lot of my colleagues had their boats taken by them," says Hans, referring to banks who repossessed boats because independent fishermen no longer made enough money to pay for them.
You could say that the gradual suffocation of the Danish seas began in 1909 with the invention of the artificial nitrogen fertilizer that transformed global agriculture. Artificial fertilizer rapidly became central to modern-day farming. By 1959, nearly 75% of farms were using fertilizer to increase crop production. At first, the growing amounts of nitrogen entering the sea did not appear harmful. During the 1960s and 70s, the extra nutrients actually increased algae and plankton growth, creating more food for some fish species. “There were actually more fish,” says Markager, the marine scientist, “but by the mid-1980s, the consequences had become impossible to ignore.”

On October 8, 1986, on Danish television fishermen in Gilleleje were seen pulling dead lobsters from the sea. The images became the subject of alarmed national conversation. For the first time, the public saw what oxygen depletion meant for life beneath the surface of the sea.
Hans, the fisherman from Bønnerup Strand, told me he was part of the television coverage himself. “Fishers had talked about pollution long before the dead lobsters,” he said. “But suddenly people started paying attention.” The public outrage pushed Denmark to act. In 1987, the country introduced its first Water Environment Plan, aiming to reduce phosphorus emissions from wastewater by 80% and nitrogen emissions by 50% within five years. For many fishers and marine scientists, it became the first real sign that the environmental crisis in Danish waters was finally being taken seriously. During the 1990s, nitrogen and phosphorus pollution declined significantly. Water in several fjords and coastal areas became clearer, and conditions slowly began improving. For a moment, it appeared the damage could still be reversed.
But by the early 2000s, many coastal fisheries were once again experiencing declining catches and, with it, a growing uncertainty about the future. Hans was one of those affected. Coming from a family that had fished for five generations, the harbor was never a tourist destination for Hans. It was a way of life. But on a sunny Friday in April back 2005, he sailed out to Kattegat for plaice. He knew it was over. “I said to my employee: “this is the last trip. I start working on land from Monday.”” He had made the decision months earlier, as the numbers of fish dwindled and regulations tightened.
It wasn’t an easy choice, but he had four children to think of. Climate change had taken away his livelihood. “You can’t do anything about it,” he said. “If you think too much about it, you go crazy.” Researchers describe this kind of environmental grief as solastalgia, the distress caused by watching a familiar environment change beyond recognition. Unlike homesickness, solastalgia happens while still remaining in the same place. For coastal fishers, the sea remains physically present, but the ecosystem they once knew and depended on, is disappearing.
Adapting has always been part of the job, says Hans. “There has always been a species that disappeared and then another one came.” But eventually, nothing was replacing what was lost anymore.

In 2002, marine scientists Stiig Markager and Peter Bondo Christensen from DMU, the Danish Environmental Research Institute, published research showing that around 75% of Denmark’s nitrogen emissions originated from agriculture through waterways and atmospheric pollution. The findings intensified tensions between marine scientists, politicians, and agricultural organizations about who was responsible for the declining marine environment.
In response to the worsening marine crisis, Denmark established DMU in 1989 to monitor oxygen depletion, nutrient pollution, and ecological changes beneath the surface. But their findings were inconvenient. By 2007, after nearly two decades as an independent institution, DMU was folded into Aarhus University as part of a wider restructuring of Denmark’s research sector. The decision sparked criticism from several environmental researchers and organizations, who feared the changes could weaken the independence of Danish environmental monitoring.
“Agriculture succeeded in closing DMU,” former researcher Bo Normander told the media. “Nature has lost.” In 2015, the Danish government introduced the controversial Landbrugspakke, easing environmental regulations on fertilizer use in an effort to increase agricultural production.
Critics warned that the policy could worsen nitrogen pollution in Danish waters at a time when oxygen depletion remained a recurring problem. In the years that followed, researchers from Aarhus University reported rising nitrogen emissions instead of the reductions politicians had promised. Markager argues that despite decades of environmental warnings, nitrogen pollution reductions largely stalled. While nitrogen pollution in Danish waters declined significantly after the first Danish Water Environment Plans in the 1980s and 1990s, researchers say the reductions have largely stagnated over the last 20-25 years.
Now, Denmark is trying to reverse that trend. In the first week of September, the country passed a historic new law changing how agricultural nitrogen is regulated. The law will take effect in 2027 and represents a significant tightening of the rules introduced in 2015.
Under the system introduced in 2015, farmers were allowed to fertilize closer to what was considered the agronomic optimum for their crops, while still operating within nationally defined nitrogen quotas and other rules. The new system moves in the opposite direction. Instead of relying primarily on broad national rules, nitrogen regulation will increasingly take the environmental sensitivity of individual areas into account.
Where a farm is located will thus matter much more. The requirements will vary depending on factors such as whether fields drain towards vulnerable rivers or coastal waters, and whether they lie above areas important for groundwater and drinking-water protection. For farmers, this means that the amount of nitrogen they can use will become more restricted in areas where the surrounding environment is particularly vulnerable.
For fishermen like Brian and Hans, the law represents a change they have long been asking for: an attempt to redress the damage done to Danish seas.
“I don’t think we’ll have fish out here ever again.” said Hans Fisker, owner Møllefisk at Bønnerup Strand“Quite a lot of my colleagues had their boats taken by them." Boat on land, Bønnerup Strand.
But understanding how the water became polluted is more complicated than it first appears. Much of the pollution data commonly referred to in public debates focuses on point-source pollution, which emanates from identifiable sources like wastewater treatment plants, industrial discharge, and fish farms, and is generally easier to measure. But most nitrogen pollution in Danish waters actually comes from diffuse sources, mainly agricultural runoff carried from fields through rainwater, rivers, groundwater, and the atmosphere. Unlike point sources, diffuse pollution is far harder to measure directly and comes with greater uncertainty in the data. As a result, wastewater pollution can often appear to be the biggest issue, even though agriculture remains the dominant source of nitrogen input into Danish waters.
For Hans, the consequences appear almost irreversible. These days, the fish often do not return. “There are still plaice here, but they’re too thin. They don’t gain weight.” Scientists point to several overlapping causes, and the suggested solutions are just as diverse. Activists call for stricter rules, fishers say there are already too many. Farmers reject blame, and governments insist wastewater is already being purified. Plenty of fingers are being pointed, but the problem remains.
Hans doesn’t expect it to change. “I don’t think we’ll have fish out here ever again.” These days, he’s on the other side of the industry, buying catch from fisheries and selling it to customers. “People have to get used to the fact that we don’t always have everything available on demand. With a changing climate, fish shops may no longer offer cod, salmon, or plaice like we’ve been used to.” Instead, he says, squid is becoming the new normal.
Still, while independent fisheries disappear, the demand for fish continues to grow. Instead of restoring the ocean, parts of the fishing industry are increasingly moving onto land.
In northern Denmark, companies like Skagen Salmon are now raising fish entirely inside closed artificial systems, where the water, oxygen, and temperature are carefully controlled. Outside, Skagen Salmon looks like a factory. No windows, just a large grey box near the coastline.
If the building had windows, the fish inside could look out at the sea. But these fish will never see, taste, or feel those waters. Instead, they are raised in artificial tanks until they reach market size. They are then slaughtered and sold to supermarkets and fish shops across the country.
